Abstract
The invention relates to the field of intelligent control, and discloses a substation outdoor terminal box heating system. The system comprises a system power supply, a microcontroller, a temperature and humidity sensor, a temperature and humidity display, a drive circuit, a multi-way switch, and a heater. The system power supply provides power for the whole system. The temperature and humidity sensor transmits a temperature signal and a relative humidity signal to the microcontroller. The microcontroller produces a drive signal and transmits the drive signal to the drive circuit. The drive circuit is connected with the multi-way switch and the heater. The multi-way switch controls on-off of the heater. The temperature and humidity display is used to display the temperature and relative humidity of an outdoor terminal box. The substation outdoor terminal box heating system of the invention has the actual effects of convenient switching-on/off, precise control, temperature and humidity display, and the like.
Description
Technical field
The present invention relates to field of intelligent control, particularly relate to a kind of outdoor terminal box of transformer substation heating system.
Background technology
When air humidity is larger, outdoor terminal box of transformer substation surface and inside have condensation to produce, the electrical equipment of condensation to outdoor terminal box inside has serious harm, produce to prevent condensation, outdoor terminal box has installed well heater, but the control of present transformer station to outdoor terminal box well heater is relatively backward, some well heaters perform practically no function.
Outdoor terminal box of transformer substation is without ventilation equipment and be in wind, drench with rain, in the rugged surroundings such as to be exposed to the sun, if now ambient humidity is larger, temperature is lower just there will be dew condensation phenomenon, condensation can make the terminal block of terminal box corrode, even there is short circuit, have great harm to the reliability service of substation equipment.
In order to prevent condensation to the harm of terminal box, the measure that transformer station generally adopts has following several: one is place hygroscopic agent bottom terminal box, and two is mounting heaters on the basis of placing hygroscopic agent.The control of well heater is divided into two classes: a class is the direct control heater of little air switch, and two classes install temperature-humidity controller on the basis of a class, but this two type systematic is all undesirable through practice examining effect.Under the pattern of present O&M integration, the workload at O&M station is very large, and well heater is moved back in throwing needs in order terminal box throwing one by one to move back, and adds the workload of operation maintenance personnel.The defect of one type systematic is when humidity is lower, and well heater continuous firing can make terminal box temperature too high, the electrical equipment aging speed in terminal box can be made to accelerate, even occur the situation of insulation damages when temperature is too high.Although two type systematics have temperature-humidity controller, field control effect is undesirable, and frequent temperature-humidity controller is inoperative, has become again a type systematic.On-the-spot temperature-humidity controller often needs to change, and wastes human and material resources and financial resources.For appeal situation, need to improve outdoor terminal box of transformer substation heating system.
