Problems solved by technology
Damage to any part of the air compressor system can cause the air compressor system to fail to provide normal working pressure for the circuit breaker, resulting in low air pressure alarm of the circuit breaker, zero pressure lockout, and even fault leapfrogging, expanding the fault range of the power grid, and economic losses are difficult. estimate

Embodiment Construction
[0013] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0014] An emergency device for a circuit breaker air compressor system with a pneumatic mechanism, which is composed of a trolley 4, a control cabinet 1, a jack 2 and a hook 3. The control cabinet is fixedly placed on the upper part of the trolley, and an air compressor system is installed inside the control cabinet. Jacks are provided at the front and rear of the trolley, and hooks are provided at the front and rear of the trolley. The rollers at the bottom of the trolley have brakes. The jack is used to lift the trolley for easy hoisting. The hook is used for carrying the device.
[0015] The air compressor system is mainly composed of air filter 5, compressor 6, motor 7 and air pipeline. The outlet of...

The invention relates to an emergency device for an air compressor system of a pneumatic-mechanism circuit breaker. The emergency device is characterized by consisting of a trolley, a control cabinet, lifting jacks and lifting hooks, wherein the control cabinet is fixedly arranged on the top of the trolley; the air compressor system is arranged in the control cabinet; and the front and the back of the trolley are provided with the lifting jacks and the lifting hooks. The emergency device for the air compressor system of the pneumatic-mechanism circuit breaker can timely provide operating energy for the circuit breaker when the air compressor of the circuit breaker fails, so that an operating mechanism of the air compressor is restored to be in the normal working pressure state; and therefore, the unplanned stop of the circuit breaker can be avoided to improve the reliability, and fault overriding can be avoided to ensure the safe and stable operation of a major network.
Description
technical field [0001] The invention belongs to an electric power maintenance device, in particular to an emergency device for a circuit breaker air compressor system of a pneumatic mechanism. Background technique [0002] At present, a large number of pneumatic mechanism circuit breakers are being transported in the power main network, classified according to the voltage level, involving 550kV, 220kV, and 110kV; classified according to the type of circuit breaker, involving GIS, tank circuit breaker, and porcelain column circuit breaker; , involving ZF6, LW13, LW14, LW15, etc. The motor, air pump, air filter and pipeline of the circuit breaker together constitute the air compressor system, which provides operating energy for the circuit breaker. Damage to any part of the air compressor system can cause the air compressor system to fail to provide normal working pressure for the circuit breaker, resulting in low air pressure alarm of the circuit breaker, zero pressure locko...
