Embodiment 1

[0023] The following is an example of the application of the vertical buffer type gas insulated circuit breaker of the present invention. Figure 1 to Figure 6 Let me explain. figure 1 In the shown buffer type gas insulated circuit breaker, a circuit breaker 20 is arranged in a metal cylindrical container 10 filled with an insulating gas.

[0024] The circuit breaker 20 is composed of fixed and movable main adapters 21, 22 through which electric current flows, fixed side and movable side arc adapters 23, 24 that generate arcs during the breaking operation, and an insulating nozzle provided with 27 buffer cylinder 25 and piston 26 constitute the buffer device, etc., provided in the fixed side and the movable side cylindrical conductors 28, 29 facing each other and the inside of the insulating tube 30 interposed therebetween.

[0025] The buffer cylinder 25 of the buffer device is connected with the operator (not shown) through an insulating rod 31 and a lever 32 . When the op...

Abstract

The present invention provides an economic buffering gas insulation circuit breaker with small volume and height using a manipulator with small operation force. A container (10) filled with insulation gas is at least equipped with fixed and movable main adapters (21, 22), fixed side and movable side electric arc adapters (23, 24), a buffering device having a cushion cylinder (25) and a piston (26), and a circuit breaker part (20) having an insulation nozzle (27) for spraying the insulation gas compressed by the buffering device to the electric arc between the electric arc adapters when the current is break; the front end of the insulation nozzle (27) is provided with an e-shaped press part (27A) that is capable of moving in the inner side of the insulation nozzle, and a hollow cylinder part (33) configured with the fixed side electric arc adapter (23) with one heart, the hollow cylinder part (33) is provided with a press plate (34) for forming a gas exhaust opening (35) on the opposite side of the insulation nozzle, the high-temperature and high pressure insulation gas is held between the e-shaped press part (27A) and the press plate (34) of the hollow cylinder part (33) for some time, and applies pressure to the e-shaped press part (27A).

Description

technical field [0001] The present invention relates to a buffer type gas insulated circuit breaker, in particular to a buffer type gas insulated circuit breaker capable of reducing the operating force of an operator driving a circuit breaker when a current is interrupted. Background technique [0002] Generally, a buffer type gas insulated circuit breaker is installed in a metal container, and is equipped with a circuit breaker composed of a fixed and movable main adapter and other parts. At the same time, the container is filled with SF with good insulating arc suppression 6 and other insulating gases. [0003] As we all know, the composition of the breaking part includes: fixed and movable main adapters connected to the energized conductors, arc adapters on the fixed side and movable sides, buffer cylinders that form buffer devices for compressing insulating gas during breaking operations, and The piston, and the insulating nozzle that sprays the compressed insulating ga...
