High-voltage switching spark-proof circuit breaker

Abstract

The invention discloses a high-voltage switching sparkproof circuit breaker and belongs to the technical field of circuit breaker equipment. The high-voltage switching sparkproof circuit breaker comprises a circuit breaker body, a protective cover, a box body, a pole and a switching handle. The protective cover covers the circuit breaker, so that the circuit breaker can be isolated from the external environment, dust prevention, wind prevention, heat preservation and drying prevention treatment is achieved, it can be effectively guaranteed that a heat absorption plate can rapidly receive solarradiation energy, the interiors of a first oil storage cavity, a second oil storage cavity and a water storage cavity are heated, and heat preservation treatment on the device is achieved; lifting adjustment of a first sealing gasket and a second sealing gasket can be achieved, intermittent liquid spraying lubrication treatment of the circuit breaker is achieved, the circuit breaker can be effectively prevented from generating electric sparks, normal work of the circuit breaker is guaranteed; the rotating power and stability of first fan blades can be effectively enhanced, and heat generatedby the heat absorption plate is subjected to quintuple diffusion treatment along a groove, and therefore, the heat transfer effect is better, the heat absorption effect is better, and the heat preservation effect can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of circuit breaker equipment, in particular to a high-voltage switching spark-proof circuit breaker. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Switching refers to the closing and opening of the circuit breaker. A high-voltage circuit breaker (or high-voltage switch) can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload current and short-circuit current through the function o...

Problems solved by technology

[0003] When the existing high-voltage throw-off circuit breaker is used on the plateau, due to the cold, dry and windy environment, the surface of the circuit breaker is always in a dry state, and it is easy to cause friction and sparks under the blowing of the strong wind, which affects the normal operation of the circuit breaker. use
