Abstract

The invention discloses an unattended substation accumulator room fire-proof and explosion-proof device which comprises a gas detector, a gas detection controller, a trigger module, an alternating current contactor, a time switch, a fire disaster sensor, an and gate circuit, a fire extinguishing controller and an alternating current (AC) power supply. According to the device, a substation accumulator room can realize periodical exhaust with fixed time and fixed location and can realize automatic exhaust in time when encountering an explosive gas mixture, and automatic fire extinguishment can be timely realized when a fire breaks out in the accumulator room.

Description

technical field [0001] The invention relates to the technical field of fire-proof and explosion-proof electronics for power systems, in particular to a fire-proof and explosion-proof device for battery rooms in unattended substations. Background technique [0002] The normal and stable operation of the communication battery in the power system is an essential part of the safe and stable operation of the system. At present, the switching power supply used in the power communication room is automatically equalized and floated for the communication battery on a regular basis when there is no one. Charging, hydrogen gas with considerable energy will be released during charging or discharging, and a certain amount of heat will be generated at the same time; in addition, in hot summer, if the temperature rises and no air conditioner is installed, the mixture of hydrogen and air will easily form an explosive gas mixture. Moreover, the upper and lower limits of the explosion are rel...
