Or the difference according to cabinet body structure, open type switchgear, metal closed switch cabinet and metal enclosed armoured switch cabinet can be divided into
Deng.
Switchgear generates a large amount of heat at work, so that internal temperature is got higher, heat, which dissipates, does not go out to influence switchgear
The service life of interior equipment.A radiator or fan usually are filled in switchgear bottom in the prior art, distributes heat in switchgear, but
It is that extraneous dust and worm fly easily pass through inside radiator fan access switch cabinet, the inside that not only will affect switchgear in this way is clear
It is clean, and even will affect the normal operation of switchgear sometimes.
Existing underground coal mine substation is more and more designed as unattended operation transformer station, however traditional substation
Monitoring system only monitors the measuring and controlling equipment of each line segregation, relay protection and other automation equipments in real time and is uploaded to ground
City's scheduling and provincial scheduling can not carry out control to the run-time environment of each cabinet body in standing, cause due to switchgear inner ring
Caused by border tripping and fire incident happen occasionally, and existing dispatching rule also mostly not to all data in switchgear into
The requirement of row acquisition and feedback control is to be monitored in real time by photographed images or sensor at most, sends in time when there is exception
Maintenance personnel's defect elimination of showing up however, such case can not usually eliminate defect in time leads to serious consequence.
And for the electric substation under mine, high temperature and environment dusty make items of equipment be at the severe fortune of comparison
Under row environment, the timeliness of the discovery and processing for failure accident has more been tested.
Summary of the invention
The purpose of the present invention is to provide a kind of high and low voltage switchgears of radiating dustproof, are used for unattended coal mine
Lower electric substation solves extraneous dust and worm by ventilation duct, inclination wind deflector, the design for tilting wind deflector and heat-conducting plate
