Monitoring device for unmanned substation terminal box

Abstract

The invention discloses a monitoring device for unmanned substation terminal box, and the monitoring device for unmanned substation terminal box comprises a box body, provided with a temperature controlling device at the rear side plate, the special point is that each side plate in the box body is embedded with an insulation board and a phase-change material plate, the phase-change material plate is naked in the box body and arranged around the main part arranged in the box body, an automatic fire extinguisher and a smoke transducer are arranged in the box body at the upper part, the smoke transducer is connected with a controller in the temperature controlling device, the output end of the controller is connected to the automatic fire extinguisher. The overlarge temperature fluctuation in the box body caused by the rapid change of the outside air temperature can be reduced for maintaining suitable temperature running range for the box body, reducing the opening times and running time of the temperature controlling device and prolonging the service life of the temperature controlling device; the condensation or damp phenomenon caused by season alternant, larger temperature difference between day and night can be avoided, the device is prevented from corrosion, the devices in the box body can be guaranteed for working safely and stably and the unmanned unattended remote monitoring can be realized.

Description

technical field [0001] The invention relates to a monitoring device for a terminal box of an unmanned substation. Background technique [0002] The temperature control equipment is installed in the terminal box of the unmanned substation to keep the box in a suitable temperature operating range. If the external temperature changes rapidly and the temperature fluctuation in the box is too large, the temperature control equipment is frequently turned on, the operating time is long, and the service life is short. In addition, the existing unmanned substation terminal box cannot detect and judge the overheating defects of the box equipment in the early stage, and cannot detect the fire in the cabinet as early as possible, and cannot carry out fire fighting, which will cause the situation to expand. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method that can reduce the problem of excessive temperature fluctuatio...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a method that can reduce the problem of excessive temperature fluctuations caused by the impact of sharp changes in external air temperature on the box, maintain the box in a suitable temperature operating range, and reduce the number of openings and opening times of temperature control equipment. Run time, prolong the service life of temperature control equipment; avoid condensation or moisture caused by seasonal alternation and large temperature difference between morning and evening, prevent equipment from rusting, ensure safe and stable operation of equipment in the box all year round, and realize unattended remote monitoring
