A method to improve the safety of outdoor power distribution

Abstract

The invention relates to a method for improving the security of outdoor power distribution, and relates to the field of power distribution cabinets. The method comprises the following steps that S1) asolar cell panel is installed in the top of a high-voltage power distribution cabinet, and charges a storage battery; S2) the storage battery is electrically connected with a controller, a fan is installed in the lateral side of the high voltage power distribution cabinet, and electrically connected with the controller, and a temperature sensor is installed outside the high voltage power distribution cabinet, and used to monitor the temperature of the high voltage power distribution cabinet; and S3) an automatic dry powder fire extinguisher is installed in the lateral side of the high voltagepower distribution cabinet and electrically connected with the controller, when the temperature detected by the temperature sensor in S2 of the high voltage power distribution cabinet reaches a ratedtemperature, the controller controls the automatic fire extinguisher to carry out fire extinguishing on the high voltage power distribution cabinet. Thus, the high voltage power distribution cabinetitself is improved via external equipment protection, the rate of fire hazards of the high voltage power distribution cabinet is reduced greatly, and the using effect is better.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, in particular to a method for improving the safety of outdoor power distribution. Background technique [0002] With the rapid development of the power industry, distribution cabinets for installing electrical instruments are essential. As the name implies, high-voltage distribution cabinets are power distribution equipment used for power distribution, control, measurement and cable connection in power supply systems. General power supply bureaus , Substations use high-voltage switchgear, and then the low-voltage side of the transformer is stepped down to lead to the low-voltage distribution cabinet. The low-voltage distribution cabinet is connected to each power distribution panel, control box, and switch box. Inside, some switches, Circuit breakers, fuses, buttons, indicators, meters, wires and other protective devices are assembled into a power distribution device that meets the desi...

Problems solved by technology

[0003] However, the traditional high-voltage power distribution cabinet has poor heat dissipation performance during use. When the electrical equipment is damaged, it is inconvenient to repair the internal electrical components. The sealing performance of the cabinet body is poor, which is not conducive to outdoor use.

[0004] At the same time, when the outdoor temperature is high, the temperature inside the high-voltage power distribution cabinet also rises correspondingly, which may easily cause fires in the internal circuits of the high-voltage power distribution cabinet, thereby posing certain safety hazards. The solutions adopted in the prior art Generally, ventilation holes are added to the high-voltage power distribution cabinet, and fireproof materials are used at the same time, which avoids the possibility of fire in the high-voltage power distribution cabinet to a certain extent, but there are still certain potential safety hazards. When the high-voltage power distribution cabinet fires, People can only watch the fire and do nothing
