A battery cabinet of a substation and distribution station using a constant temperature and temperature adjustment device

Abstract

The invention relates to a storage battery cabinet with a constant-temperature adjusting device for a power transformer and distribution station, belonging to the field of direct-current power supplies of power transformer and distribution stations, wherein a cabinet type air conditioning device is arranged outside the upper part of a front opening door or a rear opening door of the cabinet body; an air inlet and an air outlet of the cabinet type air conditioning device are arranged to pass through the front opening door or the rear opening door towards the interior of the cabinet body of the storage battery cabinet; an electric heating gas atomization device is arranged outside the lower part of the front opening door or the rear opening door; a condensate water discharging pipe of the cabinet type air conditioning device is connected with the electric heating gas atomization device; an air exchange fan is arranged on the top of the cabinet body; a turnover electric air exchange valve is arranged at the air inlet end of the air exchange fan; and the air inlet end of the air exchange fan is communicated with the interior of the cabinet body of the storage battery cabinet through the turnover electric air exchange valve. According to the invention, constant temperature and ventilation of the storage battery cabinet can be kept; the problem that condensate water generated by the constant-temperature storage battery cabinet in the operation process cannot be discharged can also be solved; the operation service life of a storage battery can be greatly prolonged; simultaneously, the capacity of the storage battery can also be ensured; and operation safety and reliability of a power grid can be easily ensured.

Description

technical field [0001] The invention belongs to the field of direct current power supplies of substations and distribution stations, in particular to a storage battery cabinet used for the direct current system of substations and distribution stations. Background technique [0002] The DC system that provides power for the operation and control system of the substation or switch station (hereinafter collectively referred to as the substation) is the heart of the substation, and the power to keep the heart beating is the battery. Once the battery fails , which directly affects the safe operation of the power grid. [0003] Once a substation is put into operation, the DC system in the station starts working at the same time. Currently commonly used valve-regulated battery, although it saves special maintenance work, it has very high temperature requirements. Especially in the high temperature environment, the capacity of the valve-regulated battery is difficult to be suffici...

AI Technical Summary

Problems solved by technology

[0016] The technical problem to be solved by the present invention is to provide a battery cabinet of a substation and distribution station using a constant temperature and temperature adjustment device. On the basis of not affecting the original basic structure of the existing battery cabinet, a special cabinet is set on the door of the battery cabinet Air conditioner, install a flame-retardant insulation material layer inside the battery constant temperature cabinet, install a micro fan and a replica electric ventilator on the top to keep the constant temperature and ventilation of the battery cabinet, so as to ensure that the operating environment temperature of the battery is not higher than 30 At the same time, an electric heating gas atomization device is used to solve the problem that the condensed water generated by the constant temperature battery cabinet cannot be discharged during operation, which can greatly prolong the service life of the battery, and at the same time ensure that the air humidity in the cabinet will not Too high; while prolonging the service life, it can also ensure the capacity of the battery, which helps to ensure the safe and reliable operation of the power grid
