Intelligent PLC TransformerFan Control Box
Intelligent PLC Control Box forTransformer Fan is a new type intelligent transformer temperature controldevice equipped with Siemens S7200 PLC as the control center, has powerfulcontrol function, clear and concise wirings inside, and easy to operate andmaintain.
Traditional control box for transformer fans adopts time relay, motorprotector and etc to form required input and output signals, and achieves thecontrol function of fans by a combination of time relay and open-close contactpoint. This traditional control method is limited by the scope of timeadjustment, has lower accuracy of time adjusting, inflexible control logic, andcomplex electrical logic circuit, it is difficult to change and maintain infuture.
After using PLC as the control center, the simulating volume collectsthe temperature values from the temperature sensor of transformer, the fan canbe controlled to switch on/off by the output points of switching volume of PLCprogram control in accordance with the temperature range in PLC, the originalmechanical type time relay has replaced by the Timer in the PLC; the alarmcontact points of fan protector is also connected to the input port of PLCswitching quantities and is directly monitored by the PLC to protect all fans.
Even more importantly, PLC control system can control the fan oftransformer to rotate at regular time in accordance with the internal tuningtime, which not only meet air-cooling, but also effectively extend the fan’sservice life, and significantly reduce the operation failure rate of the fan.
PLC free port is made into 485 port, which follows the normal MODBUS agreementand can be used as RTU (Remote Transmission Unit) for the power system"four remote" control.
Structure
The product is composed of Siemens S7200 PLC (CPU+ module of simulatingvolume), intermediate relay, motor protector, temperature sensor, temperaturedisplay meter with signal output, housing and etc.
Characteristic
▲ PLC modularizationconfiguration is flexible, which can be made upon request.
▲ The internal programdesign of PLC is flexible and powerful, it completely replaces the originalmechanical time relay, the operation is more credibility.
▲ The control time isflexible and adjustable to meet the special requirement of the users.
▲ Wring is simple and clear and easy to install, debug and maintain.
▲Medium load fan rotation can be realized, which can extend the service life offan and reduce the fault rate of fan.
▲Provide standard 485 interface and communication agreement to meet therequirement of power automatic in future.
Application
The product is suitable for multi fan control system for four pathways andabove, especially for the situation with digital communication.
- 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:I am living in a state where there is lots of Electricity cut off in other words the Loadshedding.When I listen to radio on short wave and medium wave during no electricity ON in our town, it plays well and clear. But when electricity comes its totally inaudible because of too much noise like srrrrrrr, shrrrrrrr,trrrrrrrr. Means I have to turn my radio off. My question is what thing does this cause??
- It is interference produced by electrical equipment such as motors, TVs, transformers, computers and fluorescent lamps. I guess your radio is battery operated. If you take it a mile or so outside the town, you will find you get good reception with no noises. I get this at home too. I find if I want to listen to short wave, I need to turn everything off, including fridge, TV and computer. You could try turning everything off in your house and see if it helps.
- Q:a small fire that is at the outlet
- Turn off the power if possible. Electrical fires can be put out with water, if you do not have a dry chemical to use to smother the flame. Electrical equipment will eventually deenergize itself when the conduction material burns through to the point of non-conductivity. The problem with electrical fires is that they spread to the surrounding materials. When those surrounding materials are flammable, that is the real concern.
- Q:a. nuderwriters laboratories b. national fire protection association c. national eletrical contractors association d. institute of electrical and electronics engineers
- a. underwriters laboratories
- Q:I know that means i'll choose my job at basic but does it mean that I could get a job I don't want? I really want to do Biomedical Equipment Tech.
- absolutely you can be given a job you don't want. if Biomedical Equipment Tech is considered part of the Health care field, you won't be offered that job.
- Q:I was thinking of making a video game collection, I allready have a big one but only containing systems and games with CDs. But no collection is complete without the retro NES or SNES or the old school consoles with cartridges. My question is where would be a good place to store them? Because god knows how difficult it is to find a complete set with the box and Manuel and everything so I'll have to deal with just buying the cartridge. If you could help out I greatly appreciate it!
- you always wanna store any kind of electrical equipment in a cool dry place. when it comes to Nes stuff same thing, if you really wanna make sure they will be good to go use a tote container or plastic cooler. something with a sealable possibly water proof lids. i have all my nintendo stuff sitting in a red igloo cooler in my storage unit. it has been there for over three years now and nothing wrong. just make sure you use a qtip and some alcohol to clean the pins up nice before placing in any system. you dont wan any dust that might have collected to go inside your machines.
- Q:i pods,cameras,nentendos, ect
- right here's a itemizing of prohibited and authorized products from the Transportation protection administration. Airline policies could be extra strict than TSA policies, yet for many visitors - those no longer carrying radioactive isotopes or something like that - the TSA regulations are the proper regulations.
- Q:A question for electriciansi am getting a bachelors degree in entertainment technology. The apprenticeship program is closed but i would like to get a head start for the next go around. Should i go to school and get a masters in electrical engineering or should i become a grunt and get the experience? orwhat do you guys think? I know local 3 is hard to get intovery hard???
- If I have been hiring an electrician, i'd sidestep every person with a posh enterprise call, and that i'd probable leaf by using telephone e book in alphabetical order, so i'd propose something like Abbey electric powered centers (except you're blessed with a time-honored or surname that comes early interior the alphabet).
- Q:If this is maintained, but voltage changed from 480V to 240V, by what ratio will supply line losses change?
- Power voltage x current Therefore current power/voltage. Thus, if power is constant at 2000kW current at 480 volts will be: I 2000,000/480 4166.67amps At 240 volts: I 2000,000/240 8333.33 amps However, line losses are current (squared) x resistance Thus the ratio will be 4166.67 (squared) / 8333.33 (squared), resistance remaining constant of course. I make that 0.25 (or 4, if you are thinking that way up!) That help?
- Q:If i were to give a hybrid vehicle to a teenager, and they decided to add a bunch of high powered electrical equipment:1. Does this utilize the same battery that the car motors use to propel the car.2. Do gas-electric hybrids have alternators capable of generating electricity while the car is running?3. What are the limitations of adding additional electrical accessories to the car? ie. DVD players, video screens, amplifiers, extra power outlets for laptops
- 1 Yes there is a seperate battery for auxillaries and a seperate battery that runs the electric motor/charger. 2 the alternator that runs the auxillaries is a normal 60 to 90 watt unit. It cannot charge the batteries that drive the car. 3 no differant than addind to a regular car.
