When breaker chamber had an accident, pressure was washed plastic fastening open, and pressure relief plate is opened at weak spot place bending pressure relief opening, discharged internal pressure from trend cabinet rear portion, simultaneously internal fault was limited in this compartment; The safety of operating personnel and switch cubicle in the time of can guaranteeing internal fault takes place.
Described pressure relief plate is installed in behind the cabinet on the cover plate apart from ground＞the 1800mm place.
Be provided with pressure relief device at bus-bar room; Described pressure relief device is arranged at the switch cubicle top; Top blind flange lamina tecti and pressure relief plate by switch cubicle are formed, and on lamina tecti, offer through hole, and pressure relief plate is installed in the through hole of lamina tecti; Pressure relief plate is provided with weak spot; Weak spot on the pressure relief plate is set for the eccentric, and connects with metal connecting piece on the lamina tecti of switch cubicle top at that side pressure relief plate near weak spot, then connects with plastic fastening on the lamina tecti of switch cubicle top at that side pressure relief plate relative with weak spot.
When bus-bar room had an accident, pressure was washed the plastics screw open, and pressure relief plate is opened at weak spot place bending pressure relief opening, discharged internal pressure from trend cabinet top, and internal fault is limited in this compartment; The safety of operating personnel and switch cubicle in the time of can guaranteeing internal fault takes place.
In sum, the present invention compares the following advantage of prior art:
The present invention is provided with the explosion-proof relief device of the degree of protection identical with housing in bus-bar room, breaker chamber, the cable vault of switch cubicle; Personal safety can be guaranteed in the position of its pressure release outlet; Close under the explosion-proof relief device pressure relief opening normal condition; Pressure relief opening is opened under accident conditions, discharges internal pressure automatically, simultaneously internal fault is limited in this compartment.
