In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technical scheme: the rotary-type four break vacuum arc control device of this disc type, comprise vacuum interrupter and be arranged on the fixed contact of vacuum extinction chamber interior, moving contact, the insulation outer wall, be characterized in the disc type rotary-type four break vacuum arc control device of described vacuum interrupter for linking to each other with the insulation axle, one end of this insulation axle links to each other with external drive motors or rotating machinery, the other end of this insulation axle puts in the rotary-type four break vacuum arc control device of disc type and is connected with the insulating disc of two ends band conductor connecting rod, described moving contact is arranged on the end face of insulating disc two ends conductor connecting rod, described fixed contact is arranged on the insulation outer wall of the rotary-type four break vacuum arc control device of disc type, the moving contact and the corresponding fixed contact that are arranged on the conductor connecting rod end face of insulating disc two ends have formed two groups of four fracture textures altogether respectively, every group has two fracture textures and is installed in the synchronous disjunction of realization on the insulating disc jointly, adopt insulating disc to realize electric insulation between two fracture textures of every group, the moving contact that described insulation axle drives on insulating disc and the conductor connecting rod thereof rotates, and makes the moving contact on the insulation wall circumference that is positioned at the rotary-type four break vacuum arc control device of disc type realize separating effectively finishing cut-offfing of circuit with fixed contact.
In order better to realize the purpose of this utility model, described two fixed contact A and A ' are communicated with outside realization of insulation wall, during the two ends of line attachment, power source drives the positive and negative rotation of moving contact, realizes branch, the combined floodgate of four fractures respectively for two fixed contact B of lower end and B '.
In order better to realize the purpose of this utility model, described fixed contact A and B insert a circuit, and when A ' and B ' inserted another circuit, power source drove the positive and negative rotation of moving contact, two groups of same time-divisions of double break mouth structure, combined floodgate.
After electric pressure improves, can be by improving moving contact and fixed contact disjunction distance, and increase disk diameter enough insulation distances are provided, the distance of dynamic/static contact adjusted from the axle center, promptly increase the moving contact linear velocity that is positioned on the circumference, guarantee the requirement of breaking speed.
Compared with prior art, the beneficial effects of the utility model: owing in vacuum circuit-breaker, installed rotary-type moving contact of disc type and four fracture coeneciums, the moving component of equipment is greatly reduced, the spatial placement compactness, device structure more becomes to oversimplifying, user's operation and repair and maintenance had both been made things convenient for, make that the equipment work process has embodied that security performance is good, operational reliability is high, function conversion variation etc., also greatly reduce the making production cost simultaneously, improved the stability and the useful life of whole vacuum circuit-breaker system works.
