Abstract
The utility model relates to an electrical device, concretely, a permanent magnetic operation mechanism of single phase vacuum circuit breaker. The technical plan of this utility model is that the model comprises three-phase arc-removing rooms, and three dependent permanent magnet operation mechanisms. The movable contact of every room of three-phase arc-removing room is connected to one of the permanent magnet operation mechanisms respectively. The benefit effect is that a direct connection way of the movable contacts between the permanent magnet operation mechanisms and the arc-removing rooms is adopted to greatly simplified the transmission mechanism between the permanent magnet operation mechanisms and the arc-removing rooms, and no rotating movement happens during the running operation. In addition, the control to permanent magnet operation mechanisms is flexible, and separated control to the on-off of the three-phase arc-removing rooms of the vacuum circuit breaker can be achieved according to the running condition of circuits.
Description
Technical field
The utility model relates to power equipment, more particularly, relates to Single-phase vacuum circuit breaker permanent-magnet operation mechanism.
Background technology
Existing permanent-magnet manipulating mechanism all is to be connected with the actuating bar by three linkages, with branch, the feed motion of permanent-magnet manipulating mechanism actuating simultaneously three-phase arc control device, makes three-phase branch, feed motion interlock.The transmission mechanism that this permanent-magnet manipulating mechanism contains is more, and the loss that this can increase on the one hand energy makes mechanism's volume bigger on the other hand, thereby disagrees with the little development trend of the operation energy consumption of operating mechanism, and the reliable shape of actuating of mechanism is reduced.In addition, the interlock of the moving contact of three-phase arc control device under special circumstances, can not be distinguished actuating as required.
Summary of the invention
The purpose of this utility model is to design that a kind of energy loss is few, volume is little, can show the Single-phase vacuum circuit breaker permanent-magnet operation mechanism that vacuum circuit-breaker ruuning situation is controlled respectively, realizes by following technical solution:
It comprises independently permanent-magnet operating mechanism of the three-phase arc control device of vacuum circuit-breaker and three, and the moving contact of each phase arc control device of described three-phase arc control device connects a described permanent-magnet operating mechanism respectively.
Described permanent-magnet operating mechanism is made up of static iron core, moving iron core, coil, permanent magnet and connecting rod, and described coil, permanent magnet place the outside of the moving iron core in inboard of static iron core, and connecting rod is connected with moving iron core is coaxial, and its end connects a pairing phase arc control device moving contact.
The beneficial effects of the utility model are: permanent-magnet manipulating mechanism of the present utility model is directly to link to each other with the moving contact of arc control device, improved between existing vacuum circuit-breaker permanent-magnet manipulating mechanism and the arc control device moving contact connected mode by linkage, simplified transmission mechanism like this, in the process of permanent-magnet manipulating mechanism drive arc control device moving contact motion, there is not rotational motion simultaneously, make permanent-magnet manipulating mechanism lower to the requirement of DC power supply, greatly reduce the power consumption of permanent-magnet manipulating mechanism motion process, lower DC power supply voltage can make permanent-magnet manipulating mechanism drive arc control device and finish branch, closing operation.Record according to test, closed procedure wasted work of the permanent-magnet manipulating mechanism of the utility model structure is about 50 joules, compares for 150 joules with a closed procedure merit of existing permanent-magnet manipulating mechanism, almost is reduced to original 1/3.The permanent-magnet manipulating mechanism operation energy consumption of the utility model structure has only about 130J, compares with the 200J of existing permanent-magnet manipulating mechanism operation energy consumption, reduced about 70J, and the parameters of vacuum circuit-breaker also can both meet the demands.In addition, flexible to the control of permanent-magnet manipulating mechanism, visual circuit ruuning situation is controlled respectively branch, the combined floodgate of vacuum circuit-breaker three-phase arc control device respectively.
