Abstract

The hydraulic pressure exhaust device of breaker comprises the hydraulic bunker. The exhaust mechanism and fire prevention chamber are set above the hydraulic bunker; the exhaust mechanism comprises the valve body, the piston channel and exhaust channel are set inside the valve body, the piston rod is set inside the piston channel and the piston rod has piston installed at the lower end and primary thrust spring set at the upper end; the exhaust chamber is set in the middle of exhaust channel and the columnar vertical bar is set inside the exhaust chamber to seal the exhaust channel; the traverse connection channel is set between the exhaust chamber and piston channel in which the motion bar is set.One end of motion bar connects the vertical bar and arc portion is set at the other end. The arc groove corresponding to arc portion is provided on the piston bar; the traverse secondary thrust spring is set between the vertical bar and exhaust chamber; the connection pipe is set at the upper end outlet of exhaust channel and inlet of fire prevention chamber, the fire prevention chamber is filled with water, and the lower end of connection pipe stretches into the water below. The device can realize the automatic exhaust for oil gas accumulated inside the hydraulic bunker with simple structure and excellent safety performance.

Description

technical field [0001] The invention relates to an automatic exhaust device, which belongs to the field of power systems, in particular to a hydraulic exhaust device for a circuit breaker. Background technique [0002] The high-voltage circuit breaker is also called a high-voltage switch, which plays a control role in the high-voltage circuit. It cuts off or closes the no-load current and load current in the high-voltage circuit during normal operation, and quickly disconnects the circuit under the action of the relay protection device in case of a fault. . The working state of the circuit breaker, that is, its opening or closing action is controlled by its action mechanism. Therefore, from the medium used by the action mechanism, it can be divided into: oil circuit breaker, sulfur hexafluoride circuit breaker, compressed air circuit breaker devices, vacuum circuit breakers, etc. Most of the existing oil circuit breakers use hydraulic oil. During the operation, with the wo...
