Intelligent LV reactive compensation box
1. Purposes and characteristics
LV intelligent reactive compensation box of XBZW type can be installed with the transformer on the same pole or the linepole or the wall, etc. It keeps the priority of power factor on on-load feedpoint by selecting suitable capacity,
LV intelligent reactive compensation box ofXBZW adopts distribution intelligent monitor terminal as the control core, the intelligent monitor terminal adopts full digitized design，AC sampling, man Machine Interface of a large screen LCD of 128*64 lattices, and full metal enclosure design to improve efficiently the index of electromagnetism compatibility.
The installation of it is in accordance with the DIN standard, with the installation of an embedded/wall mounted series, the main board adopts AMT SMT (surface mount technology) equipment with power distribution monitor,reactive power compensation, harmonic analysis, incident record, electrical energy measuring, I/0 interface, and temperature sensor interface. The device provides serial port 1 of RS232/485 and serial port 2 of RS—485, the serial port 2 is a data transmission serial port to mainly support the multi-function electronhour meter. The communication method of serial port 1 supports twisted-pair, coaxialline, data radio and CPRS, which also can be commutated with the cooperation of light MODEM and optical fiber.

3. Function description
This equipment can record once after every 15minute interval, and can save 90 days history records. The record density can be chosen by 15 minute, 30 minute, 45 minute, and 60 minute. For the operation of this equipment, please see the communication rule as a reference.
4. Guide line for switch control
The controller complies with the control ruleof the shape of” # “, the users can reset the upper or lower limit for eachphase and reactive power.
1) The controller is in the state of auto switch when the voltage is between UL and UH. (UL is under voltage threshold for the users, UH is over voltage threshold for the users)
2) It can be blocked when the voltage is lower than UL. It can not be put into use when the lack of reactive power, and the parts that have been put into operation should be cut off, it can be unblockedand returned to the state of auto switch when the voltage is higher than UL.
3) It can be blocked when the voltage is higher than UH. It can not be put into use when the lack of reactive power, and the parts that have been put into operation should be cut off, it can beunblocked and returned to the state of auto switch when the voltage falls backto UH-6.
4) In the state of auto switch, the controller measures on-load reactive power, if the value of on-load inductive reactive power is larger than the set value of switch on, then the capacitor switches in, the capacitor will switch out if the capacitive reactive power is more than the set value of switch off.
- Q: If it is, why?
- A house is usually grounded through its piping systems that have generous contact with the damp earth, resulting in negligible resistance. An AC circuit alternately pushes electrons into the earth and draws them back out (60 times a second) for each separate phase similar to the power generation station. Electrons need not travel from power station to house and back full cycle. A separate ground wire (cable) would be required if the earth's resistance resulted in appreciable power losses.
- Q: For example a computer or a TV.
- Yes!
- Q: I have heard, (I can't recall where), that the Earth's natural magnetic field is slowly declining. I have also heard that solar flares can disrupt the operation of electrical/electronic equipment. Would either of these natural phenomena affect the operation of electronic/electrical equipment? Please answer each query briefly, and provide links if possible.
- The magnetic field of the Earth is only an issue with things that measure or otherwise require the presence of the field, specifically compasses, only at that, only magnetic compasses. Most modern navigational equipment use gyrocompasses, which measure the rotation axis of the Earth and therefore, do not care whether a magnetic field exists. If the magnetic field were to disappear tomorrow, only magnetic compasses and certain geologists would be affected.
- Q: for my hair dryer and other electrical equipment
- Its a 3 pin plug herenot to worryjust get your stuffyou can buy a converter herealso electricity is 110V. so be mindful of that as well.cheers
- Q: I just heard tapping noises coming from the back door. The back door leads to the laundry room and multiple storage rooms. There is also all the heating and electrical equipment down there. The leak is coming from a pipe at the ceiling in a storage one, the room beside all the electrical equipment. The floor is soaked and the water is leaking a lot. Am I in danger?
- Are you in danger only if the water comes in contact with electrical wires yes have the pipe repaired call a plumber don't wait til Monday when it will be cheaper because it won't when the ceiling collapses some one may get hit with plaster board and the. You wind up with an even bigger hole . The longer you wait the more it will cost. Especially if a fire were to start remember water and electricity don't play well together some one can be electricuted
- Q: I'm currently doing a 3 year advanced diploma for electronics engineering program. However, I don't feel it could really lead to much possibilities. What do people think?Are there any electronics engineers here in the room?? If so, what challenges do you face??
- It's pretty booming right now, and probably will be for the next couple of decades at least. As far as possibilities go, what are you looking for? Some EE's start their own companies and make millions. It's as much as what you make of things as it is about hopping on the right train to take you where you want to go. The downside of engineering has to be the pressure and the deadlines. Marketing and money drive engineering. And the market doesn't want to wait forever for the next gismo. Your design has to be finished by a certain time or else the whole bridge project gets held up, etc.
- Q: charges, what other taxes, charges etc am i obliged to pay to stay within the law??
- Thats a reflect of the IO interface. Same with me too
- Q: I seem to have an adverse affect on computers and electrical equipment. My sheer presence seems to upset them.I'm not a stranger to technology, so it's not me being dim, but more and more often I've crashed supermarket checkouts, I was even sent to the other side of a store by my husband because the computer our details were being loaded on crashed time after time. I walked away and all was well in the world (well the store anyway). My laptop (even with the latest updates) has a mind of it's own sometimes. Coincidence or am I electrically overcharged?
- its not only you, it happens to me too, i guess it is something to do with electron
- Q: Hi, i have one question i'm would like to sell my computer (tower) on OKorder but i don't know the value of my system, it was a gift from my sister about a year ago. Here is my system specs:Black gaming case with red neon light insideAmd x2 3800+ 2.0ghz.2GB of Ram ddr2 667mhz.Asus m2n-e motherboard.Visiontek Hd 2600 pro 512MB ddr2 supports direct x10.Western Digital 160 GB sata hard drive with Vista ultimate.Pci firewire card 2 ports.Any Help will be appreciatedthanks.
- Yeah, I would be surprised to see it sell for more than 400 on OKorder.
- Q: Context:Unrated electrical equipment in the dust handling equipment and area could act as an ignition source, which would result in a fire or an explosion for the dust handling equipment or rooms.
- It refers to both the equipment and the area.
