And it still works safely when the pit is immersed or the transformer is submerged. It can resist flood water disaster for effectively improving the reliability of power-supply system.
(3) Low voltage switchgear uses patent outdoor light box-type protective casing. Both sides of the casing can install all-day poster board. It uses small volume, green economic LED light-emitting component
- Q: I just recently moved into a new house and the main room is laid out weird and the only place for the TV is above the fireplace. There is a small room in the corner that the previous owners used as a small office and I would like to stick all of my equipment (AV receiver, dvd player, cable box, etc.) in there so they will be out of view. Is there a way I could do this and still use the remote from the couch and not have to do everything manually?
- there are kits in the market today that can convert infrared signals into electrical signals then back to infrared where the av equipment is. this can be done wirelessly (RF) or wired. the kits are called infrared repeaters. they have many components. a sensor reads signal. a main control unit distributes signals(wirelessly to another control unit or wired to the flashers), then infrared flashers or emitters shoot the infrared beam at each component. click on the site below for more details. an alternative is to get a universal RF remote which doesnt require a line of sight to work. the remote sends signals to a contol unit where the signals are distributed to infrared flashers on the components to be controlled. this way, no wiring through the walls needs to be done. that can also be possible by using RF to transport signals from sensor to flasher (mentioned in above paragraph) if u prefer a cheaper infrared remote.
- Q: I need definitions of ship EquipmentMain switchboard:Distribution bus bars:Ship service generators:Main Engines:Prime mover:propulsion generators:propulsion motors:
- Main switchboard: Is the circuit panel board that controls both 110v and 12/24 volt lighting and accessories. Much like your panel box at home. Distribution bus bars: When adding anything electrical to a boat, you use a distribution bar located centrally instead of running wires to the batteries or panel box. There is a positive bar and a negative bar. One wire will run from the bar to the battery, and that is how the bar gets power. Most bars contain 6 or 12 screws, and you attach your addition's wires to the bar. Bars can be made to handle both 110v and 12v. Ship service generators: are usually diesel or gasoline powered motors made to produce electricy. Larger boats and ships use generators to power 110v items such as air conditioning, refrigeration, etc when away from the dock. When at the dock, a large power cord is used to feed 110v to the boat, from a dockside power pedestal. Main Engines: Are the engines used to power the boat's forward and reverse movement through the water. Prime mover: is something used within the propulsion system of a ship. It efficiently transfers power from the engine to the drive shaft.similar to a transmission in a carI think, I am not 100% sure on this one. propulsion generators: are geberators that run off the main engine. On a car we use an alternator to produce 12v for lights, etc.but to power 110v items you need a generator. propulsion motors: These could be the same as the Main Engines, or it can mean the motors that power a ship's bow and/or stern thruster, which moves the boat in a sideways direction. Used mainly for docking.
- Q: i want to make a bulb on and off at intervals of say half an hour. readymade timers available in shops(india) costs much and does not support shorter intervals like half an hour. any cheaper electronic circuit which can do this control? from where can i get the circuit or its diagram?
- Depending on your skills, a CMOS 555 timer chip could probably drive a solid state switch (triac) for this interval although a more reliable timing, especially if you want exactly a 50% duty cycle, by feeding the timer output into a counter, so that the 555 cycles say 32 times (once a minute about) for each change of state of the selected output. Smaller cycle times are more stable.
- Q: I'm about to take an automotive electronics class at college but I'm just curious, what are the basics? Say I want to wire a police scanner or some type of lightbar into my car's electrical system. What would this entail? I'd have to pull away body panels, run wire, and hook it into the battery? What about fuses, safeties, etc And also how could I hook my police scanner into my speaker's system?
- Fuse blocks in cars often have SPARE (usually disused in some particular model) positions with wires already attached and within the wiring loom, with nothing connected to the end. Knowing what the intended accessory was, might allow you to connect something to its unconnected end, and always, the negative return is the car's frame. The circuit must be capable of carrying the current required. Some of these spares may be connected via the ignition switch, some may not. The next alternative is to run a new wire with a fuse inline, at the supply end at least. It is good practice to fuse the supply end, then have a further fuse at the accessory end (most accessories will already have this). The wire can often be run along and fixed to the existing car looms, passing through the firewall where the loom passes through. Again, negative is anywhere convenient on the car's metal frame. A quick and simple connection is the cigarette lighter, if fitted. Just procure a plug to replace the lighter. It can supply a fair current. So far as connecting a scanner to the existing speakers, I suggest you don't try to, unless the audio/ radio system has an accessory input. Maybe a bluetooth connection might be used, but really, the scanner's own speaker should supply the scanner sound. You can also connect accessories by splicing into existing car circuits, but I would suggest you do your college course first! You really need to understand current and wire sizes and fusing (not to mention basic circuitry!), before splicing into existing wires.
- Q: I am currently studying electrical engineering in college but Im considering maybe teaching math for a while. But I wanted to ask what the daily routine is like for an electrical engineer at workThank you
- There are different types of Electrical Engineering jobs. Could be with:- Civil engineering projects Mechanical engineering projects . Electronic engineering projects Might be an idea to enter industry and perhaps enter teaching at a later date. Not an uncommon route.
- Q: I am a commercial real estate appraiser and I oftentimes need to be specific about the electrical service available within a building. I can read the service panel(s) and total the various amps volts, but I don't know what is relevant to report. For example, I recently inspected a very large industrial building and all of the service panels combined had a total of 30,000 amp, and I also noted that it had a 3-phase unit. Is that relevant to report that is was 30,000 amp, 3-phase service? Should I also report the voltage? Should it read: 30,000 amp/### volt 3-phase service. In the future, can I just read the service panel(s) and total the numbers? Just because a panel says 4000 amps, does that mean it actually has 4000, or that it can handle that many amps?I know that's allot of questions, but any help that I can get would be helpful. Thanks!
- I believe that the sum of the individual service panels can exceed the service capacity of the building just as the sum of the individual circuit breakers in a panel can exceed the capacity of the panel. It is allowable to assume that not every load will be using power at the same time. Near the meter, there should be a master circuit breaker or set of fuses that determine the ampere rating of the service to the building. In a large industrial facility, that location may accessible only to qualified personnel, and you may need to ask a qualified person to give you a description. You should state the voltage, number of phases and current or KVA available at the meter location. For a large facility, you may want to itemize the ratings of panels serving major spaces and/or verify that all major spaces have the same voltage and number of phases available. For large industrial facilities, you should also determine if the utility or the customer owns major outdoor electrical equipment that is on the property.
- Q: Hi I'm doing a music project at the moment, writing songs, music, etc.my genre would probably be considered alternative/electronic rockMy current vision for my set up is an electric guitar and my macbook.I create most of the music via macbook (drum parts, synth parts, basically all the programing)Playing live i suppose i'd play these songs on my laptop. While i do this, i sing, and play rhythm guitar along with the samples and instrumentals on the macbook.My question is, how do I connect all this stuff on stage? Could anyone out there recommend anything that I could use to connect my macbook to speakers for performing live.p.s I know nothing of playing with electrical equipment (been doing acoustic for a very long time) all I know about live equipment is connecting a guitar to a guitar amp.so is there like a way to connect a macbook to an amp? or speaker of some sort?Thanks in advance.
- In order to get the most from your Mac as sound generator use a reasonably good audio interface (like the E-mu 0404 usb or something from M-audio). This should be connected to a mixer and this one to the PA system. You also should connect your microphone and guitars to the mixer too, so you can control the volume of each instrument, including the Mac. Although you can connect the mac directly to an Amp I won't do that in order to get control of volume and have better sound. Computers generally don't like live performing. Electric voltage can be unstable (heavy power consumption and lights on-off pattern). Use the appropriate electric equipment to make sure the computer always receive the correct amount of voltage. If not, it can fail and ruin your performance. Make a test where possible.
- Q: I don't want to light a bulb with the battery as almost everyone is doing that.So please help me an suggest any good things and tell me how to make it.I have the idea of making a small plastic fan spin but i don'nt know how to do it.
- If you have a small plastic fan with some wires that come from the motor then you're set. You just put one wire on the positve end of the battery and one end on the negative. Voila, electrical current.
- Q: i dont understand this, every surge protector claims to protect phone lines from surges but why?
- Two weeks ago we had a heavy duty thunder storm. it went through the Phone Line this is what got fried, Telephone, DSL modem. Router, Ethernet card in desktop computer, PS3 So I guess it went through phone then modem then Ethernet card, to router that was wired to the PS3. This is why you want to protect your phone lines if you have DSL. I learned a very expensive lesson. I now have my phone/DSL line surge protected.
- Q: For example, a typical multimeter measuring just 25 ohms in a closed circuit will not show continuity by beeping.
- The definition of electrical continuity is that the current will be closed by electrons and molecules. The ohms, is the resistance to the circut being closed completely, usually determined by a nominal factor in communication and audio equipment. 25 ohms is a high resistance. In other words, 4 ohm speakers will be almost twice as loud with the same applied volume than 8 ohm speakers. So your 25 ohm measurement is taking out most of the current. You are creating the resistance to the 100% continuity by 25 ohms. Ted Taff money911.ws
