Abstract
The utility model relates to an encapsulated pole indoor high voltage permanent magnetic vacuum circuit breaker with synchronous phase control. Three sets of permanent magnetic mechanisms and an encapsulated pole vacuum arc extinguish chamber are respectively mounted on the bracket from top to bottom, the moving iron cores of the permanent magnetic mechanisms are connected on the moving contacts of the encapsulated pole vacuum arc extinguish chamber by hinges to drive the action of the encapsulated pole vacuum arc extinguish chamber. The utility model is suitable for indoor control and protection of three-phase AC capacitive load and inductive load (50 Hz and 12 KV rated voltage) in industrial and mining enterprises, power plant and transformer substation, particularly suitable for occasions with frequent switch-on and switch-off of capacitor bank, furnace transformer, high-voltage motor, etc.
Description
(1), technical field
The utility model patent relates to the phased synchronized vacuum breaker of a kind of fixed sealing type indoor high-voltage permanent magnetism; be applicable to the indoor do control of industrial and mining enterprises, power plant and electric substation and the capacitive load of protection three-phase alternating current 50Hz rated voltage 12kV and the usefulness of inductive load, be particularly useful for suiting the occasion of frequent operation 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 fixed sealing type indoor high-voltage permanent magnetism phased synchronized vacuum 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: fix three cover permanent magnet mechanism and solid-sealing vacuum arc control device on the support respectively from bottom to up, the moving iron core of permanent magnet mechanism is hinged on the movable feeler lever of solid-sealing vacuum arc control device, to drive the action of solid-sealing vacuum arc control device.
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 cover permanent magnet mechanism 2 and solid-sealing vacuum arc control device 4 on the support 1 respectively from bottom to up, moving unshakable in one's determination 3 of permanent magnet mechanism 2 is hinged on the movable feeler lever of solid-sealing vacuum arc control device 4, to drive 4 actions of solid-sealing vacuum arc control device.
Claims (1)
1, the phased synchronized vacuum breaker of a kind of fixed sealing type indoor high-voltage permanent magnetism, it is characterized in that: fix three cover permanent magnet mechanism (2) and solid-sealing vacuum arc control device (4) on the support (1) respectively from bottom to up, the moving iron core (3) of permanent magnet mechanism (2) is hinged on the movable feeler lever of solid-sealing vacuum arc control device (4), drives solid-sealing vacuum arc control device (4) action.
