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.

- Q:1 explain the difference btween a conductor and an insulator in terms of the transfer of electrons. Why are problems with static electricity common in winter than at other times of the year? How could any of these problems be reduced?Why is cleaning dusting more difficult in winter?List at least 2 reason why you think plastic materials are used to cover the copper wires in electrical equipment.
- 1. In a conductor, electrons transfer easily from atom to atom. In an insulator, it is extremely hard to cause electrons to shift atom to atom. (edit) This means an electrical current cannot flow in an insulator, as electrons must move in a conductor. (end edit). 2. In winter, the air contains less moisture. Therefore static charges will not dissipate as quickly as they will in moist air, and are more easily generated. 3. For the above reason, moving dust particals can easily induce a charge in them, which will be of opposite polarity to the surface. They can be attracted back to the surface. Using a slightly moist cloth can help when dusting in winter. 4. Plastics etc. are electrical insulators. Plastic insulation is very easy to apply to a conductor by extrusion around the conductor, in a plastic extrusion machine. The material is heated to a suitable plastic constituency. Plastic insulations are NOT used in extreme heat or cold situations for conductors. If you live in the US, you will see lots of rubber insulated power leads, as plastics can get more brittle and fracture in cold conditions. Plasticity is the state between solid and liquid, which is where all plastics are worked. In fact, many materials other than plastics can be worked in a plastic state, even metals!
- Q:I want to know if it would be feasible to make exercise equipment (like a bike, treatmill, stair stepper, etc.) that would produce a small amount of electricity when used. Could this type of equipment be modified to produce enough electrical energy to make a noticeable difference in a monthly power bill? If it was feasible, think about the benefits! Not only would we have a new (albeit small) source of energy, but we might be motivated to get off our butts and exercise more. Okay, its a wacky thought, but I just wondered. What do you think?
- hi , this is absolutely possible, if a mobile requires only around 5 volts output adapter for charging, this means we in turn loose energy by steping the 240 v to 5 volts, so by using an instrument causing electromagnetic flux of 7.6 volts, which will give net output of 5 volts ( with ac derater ) , we can easily save th energy at least required for mobile charging, many more apllications can be done, a simple very simple apllication would be moving vheicles, like , dyanamos, charge the batteries fitted in side the vheicle it self and in the same manner we can have two batteris, and one will be a overflow battery, the cars, truks, and other large vheicles, daily moving at least hundreds of kilometers can produce, and store lot of energy, and save in national wealth,
- Q:1 artificial permanent 2 electromagnetic3 natural
- I suppose they all do; Electromagnets are probably the most useful as they can be switched on and off instantaneously. They are used in motors, loudspeakers, relays, televisions etc. artificial permanent magnets can also be found in electric motors, loudspeakers, reed switches etc. As far as i can think natural magnets don't have many applications. but they could be used to make loudspeakers, motors and to operate reed switches for sure. So in short, they all have several applications in electrical equipment. Sorry not to be of more help.
- Q:i am going to ship my furniture including my electronics( refrigerator, recorder, laptop, dishwasher, drier, etc) i want to now if the voltage in USA is 240v as in Dubai or 110v and i case of difference i want your advice i`ll ship them or not
- You shouldn't ship them, better to sell them and buy new ones, in the US they use 110, not like Dubai and some appliances like the fridge will not function well since its manufactured for Dubai were its hot and humid, as for your lap top no harm taking it, you can get an adapter for it.
- Q:I don't know a lot about electricity, but I know that on earth we ground our outlets, computers, etc. Do they have a means of grounding electricity in space? Are electrical systems more dangerous on spacecraft?
- We do not ground all electrical equipment. Much of it is double insulated. Grounding simply connects the chassis to Earth, so that if there is an electrical fault that makes the chassis live this is short to Earth and a person, who we might expect to be standing on Earth and not hovering, will hence be at the same potential as the chassis. The actual circuit is not grounded - its return path conencts to neutral. Precisely the same principle can be used in space, but in light of the fact that people in space may actually be floating, double insulation is safer.
- Q:i have to identify whether it is civil or criminal or both and which specific area of law involved adn discuss the key issues which are likely to be raised in court - Amanda had bought and renovated a large house which was converted into student flats, because she was running short of money during the conversion, Amanda decided to buy some second-hand gas heaters which she serviced and installed herself, despite not being qualified to do so. unfortunately, one of the heaters malfunctioned, allowing poisonous fumes into on of the flats.One of the students, Boyd was killed.His girlfriend, Celia was made seriously ill and had to spend weeks in hospital.
- Please tell me you're not a law student and this is something from the 8th grade. No college student that has your writing skills should be studying law.
- Q:I bought a used printer but it did not have the power cable with it, but I have an old power cable from another printer. The only visble difference in the cables is that the colorful end that goes into the printer has a plastic notch on it that is in a different spot. My old one has the notch in the middle where is I need it off to the left. Can't I just shave the notch off and have it fit?
- It's hard to say. Electrical equipment and parts are made for a specific reasons. Now, if you modify the power cable, it's possible that it may work. But, then again, there is also the possibility that it could do more damage than good. It will totally be your call.
- Q:examples of electrical equipment in which insulators and conductors are used.and give reasons for their usethxthe one that answers will get 10 points
- insulators are used on wires and places you don't want electricity to flow conductors are used in circuit boards and almost every electrical component. conductors are used to carry the flow of electricity.
- Q:At hwy 5 and 380 there is a bunch of large trailers,cars, and production equipment. What is being filmed there?
- I am so glad someone was able to get the info. Well I guess no Bill Smith's in the morning. Thanks for the info.
- Q:Hi. I have bought a kiln from Germany which is compatible with our electrical currents here in the UK - that much I know. It is a small kiln and can be used with just ordinary household electric. However, the electric lead is much thicker than the ordinary leads on my other electrical equipment. Is this just for added safety or what? I want to cut off the German plug and put on an English plug so I need to be sure this is ok. Help from a qualified electrician would be preferable if possible please. Thanks so much.
- The heavier wire is to prevent overheating. Cut off plug and wire as normal. Live to the right, Neutral to the left and Earth to the front pin. Luck.
