Summary of the invention: the purpose of this utility model is: provide a kind of explosion insulation performance, structure to meet national standard fully; compact conformation; be convenient to make, the wiring of connection platform is simple and reliable; volume is little, floor space is little, can make full use of the space; observe easy to operate; have intelligent comprehensive protection controlled function, cut-off the non-maintaining intelligent high pressure vacuum power distribution cabinet of mine explosion-suppression in big, the dynamo-electric life-span length of capacity, the use.Thoroughly eliminate the design hidden danger of Coal Production mesohigh controller switching equipment, improve the power supply quality of high tension distribution system under the coal mine, reduce electric energy loss, round Realization colliery down-hole switch does not have oiling, intellectuality.For realizing that the colliery power distribution automation provides equipment to guarantee.
The purpose of this utility model is achieved in that the utility model is formed by square chest type compartment flame proof cabinet, cabinet cover plate, DMC insulation compacting power transmission conductor, isolation switch, Totally enclosed vacuum circuit breaker, intelligent comprehensive controller, motor energy-stored spring operating mechanism, voltage transformer, current transformer, zero sequence current mutual inductor, piezo-resistance, High-Voltage Insulation cable, press disc type cable entry and press disc type cable connection table apparatus etc. zero, component-assembled.
The utility model has the advantages that:
1, have intelligent protection function to distribution system short circuit, overcurrent, decompression, unidirectional ground connection (electric leakage), cable insulation, to operation of equipment and control loop on-line monitoring and fault self-diagnosis function, with higher level's computer management system communication function, manual, electronic or remote control branch, closing operation function and feed-out cable discharge operation function over the ground;
2, explosion insulation performance, structure meet every regulation of GB3836 fully; Electrical insulation properties is good, humidity, anti-condensation.
3, cut-offfing big, the dynamo-electric life-span of capacity grows, need not safeguard substantially in the rated life time number of times;
4, make full use of the space, compact conformation, volume be little, take up an area of less, in light weight, cost is low;
5, be convenient to observe and operate.Integral installation, connection platform, cable are introduced, feed out simple and convenient.
