Description
Technical field
The present invention relates to a kind of ring main unit, specifically a kind of modularization solid insulation ring main unit.
Background technology
Often need that Switch main body and cable and bus are carried out grafting in insulation ring main unit to realize electrically connecting, traditionally, due to cable connection module, bus link block directly adopts common inserting mode to connect, therefore in conducting process, joint area divides uneven due to link and conductor coupling portion, electric field is easily caused to suddenly change, produce the problems such as partial discharge, two station disconnecting switchs simultaneously in existing switchgear, on-load switch and earthed switch are independent separately, install respectively, it is bulky, manufacturing cost is high, mounting and adjusting is extremely inconvenient, make its work on the spot amount very large thus, separate set-up mode makes its insulating properties and the non-constant of dependability simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of simple and compact for structure, good insulating, connection are reliable, mounting and adjusting modularization solid insulation ring main unit easily.
In order to solve the problems of the technologies described above, modularization solid insulation ring main unit of the present invention, comprise the Switch main body of integral type, the both sides up and down of Switch main body front end are embedded with input adapter and out splice going splice respectively, input adapter has an input cavity communicated with isolating switch room, also comprise the bus link block that can be connected with input adapter, bus link block comprises an input insulation crust, bus-bars conductor is provided with in input insulation crust, there is in out splice going splice one and breaker chamber, the conductor connection chamber that earthing switch room communicates, bonding conductor is mounted with in conductor connection chamber, also comprise the cable connection module that can be connected with out splice going splice, cable connection module comprises an output insulation crust, cable conductor is provided with in output insulation crust, isolating switch room is formed from top to bottom in Switch main body, breaker chamber, earthing switch room, isolating switch room, breaker chamber, the front portion of earthing switch room is separated and rear portion opened mutually,
Described input adapter is provided with input adapter flange, described input insulation crust has the bus flange of one, described out splice going splice is provided with out splice going splice flange, and described output insulation crust has the cable flange of one.
After adopting above-mentioned structure, the cable connection module that the bus link block connected due to input adapter place and out splice going splice place connect, the special construction that bus link block and cable connection module are arranged, its vibrational power flow is reasonable, connect reliable, protective is good, effectively decrease partial discharge, the reliability connected also improves greatly, this switchgear is arranged according to upper, middle and lower simultaneously, isolating switch room, breaker chamber, the front portion of earthing switch room is separated and rear portion opened mutually, the integral structure formed thus, compact conformation, good insulating, and can directly install, integrally-regulated easy for installation, connection reliability improves further, greatly reduce on-the-spot workload.
