Abstract

The invention discloses a circuit-breaker automatic air exhaust alarm device, and the device comprises a hydraulic oil warehouse. An air exhaust mechanism, a flame-retardant chamber and an alarm unit are disposed above the hydraulic oil warehouse. The air exhaust mechanism comprises a valve body, and the interior of the valve body is provided with a vertical piston channel and an air exhaust channel. The interior of the piston channel is provided with a piston rod and a piston, and the upper end of the piston rod is provided with a first push force spring. The central part of the air exhaust channel is provided with an air exhaust chamber, and the interior of the air exhaust chamber is provided with a cylindrical rod, wherein the vertical rod can block the air exhaust channel. A lateral connection channel is disposed between the air exhaust chamber and the piston channel, and the interior of the connection channel is provided with a movable rod. One end of the movable rod is connected with the vertical rod, and the other end of the piston rod is provided with an arc-shaped part. The piston rod is provided with an arc-shaped groove cooperating with the arc-shaped part. A lateral second push force spring is disposed between the vertical rod and the air exhaust chamber. The device can achieve the automatic air exhaust of the hydraulic oil warehouse, also can be manually controlled to be started through the alarm unit according to the needs or the condition of oil gas pressure, is simple in structure, and is good in safety.

Description

Technical field [0001] The invention relates to an automatic exhaust device, belonging to the field of electric power systems, in particular to an automatic exhaust alarm device for a circuit breaker. Background technique [0002] High-voltage circuit breakers are also called high-voltage switches. They play a control role in high-voltage circuits. They cut off or close the no-load current and load current in the high-voltage circuit during normal operation, and quickly open the circuit under the action of the relay protection device in the event 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 Device, vacuum circuit breaker, etc. Most of the existing oil circuit breakers use hydraulic oil. As the pump body works during operati...
