Description
Technical field
The utility model relates to the improvement technology of the power switchgear of realizing that in distribution system the synchronous interaction of three-phase power circuit is cut-off.
Background technology
For can cut-off distribution line, closure artificially controls effectively, connection is provided with multiple high voltage switchgear in the distribution system, as circuit breaker, isolating switch, on-load switch etc.Particularly in order to realize the synchronization of three-phase power line switching operation, all be provided with the three-phase link gear on its switch knife plate, its three-phase link gear includes the insulated tension pole hinged with knife plate, insulated tension pole is fixedly mounted on the metal universal driving shaft, is driven the switch gearing operation that realizes the three-phase power circuit by mechanical transmission mechanism.Total assembling structure that this realization three links is very complicated, component parts is many, the action accumulated error is big, cause the synchronism of its operational motion to reduce, the insulation high voltage performance is lower, poor safety performance, and have certain switch motion operation dead angle, make it possess separating brake, two kinds of operate condition forms of combined floodgate, can't satisfy the user and should have combined floodgate, separating brake one ground connection, three kinds of operating states of separating brake demand of selection flexibly, thereby bring many inconvenience for manipulating of user product.
The utility model content
Synchronism for its three-phase combined operation of switchgear of improving the connexon distribution line, and simplify total assembling structure of its three-phase link gear as much as possible, the utility model provides a whole set of three technical scheme that links AC high-voltage switchgear, the major technique content of this technical scheme is: this three insulated tension pole mechanism that AC high-voltage switchgear includes the switching device that is connected in respectively on each distribution line of three-phase and realize switching manipulation that links, the fixedly connected installation of insulation supporting seat that each switching device sets up by support, between the threephase switch device, the hinge axes that is positioned at knife plate is provided with knife plate insulation universal driving shaft, and the cutter plate axis of threephase switch device is fixed on this insulation universal driving shaft.
In technique scheme, its insulated tension pole mechanism is: an insulated tension pole, its top and the knife plate formation that is articulated and connected.Another of this insulated tension pole mechanism implemented structure: axle is fixed in insulation universal driving shaft one end and is provided with an auxiliary connecting rod, the outer end of auxiliary connecting rod and the insulated tension pole formation that is articulated and connected.
The three ac high-voltage switching devices that link that the utility model provides, the direct interlock of the action knife plate of switching device on the three-phase distribution circuit is fixed on the same insulation universal driving shaft, and the synchro switch that drives the switch knife plate of realizing three-phase line by this insulation universal driving shaft moves.Thereby the technical program has been simplified the interlock controlling organization of threephase switch equipment greatly, make this switching device structural integrity stronger, product shape is elegant in appearance, the more important thing is the action dead angle of having eliminated the switch knife plate, so can select to finish combined floodgate, separating brake one ground connection, three kinds of functions of separating brake easily, satisfy the multifunctional operating demand of user to product.In addition, the technical program is that direct manipulation insulation universal driving shaft drives the knife plate switching manipulation synchronously, thereby has the good performance same period, has avoided misoperation, has guaranteed the security reliability of switching manipulation.
Describe technology contents of the present utility model in detail below in conjunction with the specific embodiment structure of being given, present embodiment and its explanation mainly is to be typical case with ac high-voltage isolating switch product, to reach the purpose of drawing inferences about other cases from one instance.
