Abstract
The utility model relates to an outside high-voltage permanent magnetic synchronous vacuum circuit breaker in which an insulative frame housing is fixed on a frame, a permanent magnetic mechanism is fixed at a lower end of the insulative frame housing, an end of a drive output axes of a iron core of the permanent magnetic mechanism is connected with an high-intensity insulative pull rod, an other end of the high-intensity insulative pull rod is articulated on a movable contact rod of a vacuum interrupter and is fixed on a down-output line bus via a soft-connected down-output line terminal, the vacuum interrupter is fixed in the insulative frame housing, an immovable contact rod of the vacuum interrupter is fixed and electrically connected with an upper-input line terminal. The utility model is suitable for being used for controlling and protecting a three-phase AC 50Hz, a rated voltage 12kV, a capacitor load and an inductor load inside a mine enterprise, a power generation factory and a substation, especially suitable for being used for frequently turning on/off a capacitor group, an electric cooker transformer, a high voltage motor, etc.
Description
(1), technical field
The utility model relates to a kind of indoor high-voltage permanent-magnet synchronous vacuum circuit-breaker; be applicable to indoor do control of industrial and mining enterprises, power plant and transformer station and protection; the usefulness of three-phase alternating current 50Hz, rated voltage 12kV, capacitive load and inductive load is particularly useful for suiting frequent occasion of operating such as capacitor group, furnace transformer, high-tension motor.
(2), background technology
A major issue of primary cut-out is exactly when cut-offfing inductive and capacity load; transient overvoltage can occur and shove more greatly; this is not only unfavorable to the insulation system of power equipment, can cause that also protective device produces misoperation, influences the stability of electric power system.The primary cut-out volume that uses is big at present, installation and transportation are inconvenient, the price height.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of indoor high-voltage permanent-magnet synchronous vacuum circuit-breaker, and not only volume is little, in light weight for it, installation and transportation convenient, and reliable, and price is low.
The technical scheme in the invention for solving the technical problem is: fixed insulation bracket shell on the support, the lower end of insulating support housing is permanent magnet mechanism fixedly, one end of the power output shaft of the moving iron core of permanent magnet mechanism connects the high strength insulated tension pole, the other end of high strength insulated tension pole is hinged on the movable feeler lever of vacuum interrupter, and formula lower wire end is fixed on down on the outlet bus by being flexible coupling, described vacuum interrupter is fixed in the insulating support housing, and the stationary contact bar of vacuum interrupter is fixed and is electrically connected with last input terminal.
Totally three groups on structure between described insulating support housing, permanent magnet mechanism, high strength insulated tension pole, vacuum interrupter, lower wire end, the last input terminal can be controlled three-phase circuit.
The utility model not only compact conformation, volume is little, in light weight, easy for installation, reliable, and can be by control mutually, and simultaneous operation can avoid producing switching overvoltage, shortens the electric power system transient process, improves the quality of power supply and stability of power system.Price is low.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model schematic front view;
Fig. 2 is the utility model signal left view.
(5), embodiment
As shown in drawings, fix three insulating support housings 4 on the support 1, insulating support housing 4 lower ends are fixed a cover permanent magnet mechanism 3 respectively, one end of the line shaft of the moving iron core 2 of permanent magnet mechanism 3 connects high strength insulated tension pole 5 respectively, the other end of high strength insulated tension pole 5 is hinged on respectively on the power feeler lever of vacuum interrupter 7, and fixedly is electrically connected to down on the outlet bus respectively by formula lower wire end 6 that is flexible coupling.Described vacuum interrupter 7 is fixed in the insulating support housing 4, and the stationary contact bar of vacuum interrupter 7 is fixed and is electrically connected with last input terminal 8.Described insulating support housing 4 materials are the high-strength insulation resin, and lower wire end 6, last input terminal 8 are that copper is silver-plated.
