Abstract

The invention provides a circuit breaking apparatus. The circuit breaking apparatus comprises a solid insulating part, a transmission part and an annular dynamic sealing part; a first cavity is formed in the interior of the first end of the solid insulating part; the first cavity is communicated with the end plane of the first end of the solid insulating part to form an avoidance opening; at least a second cavity is formed in the interior of the second end of the solid insulating part; a creepage-proof structure is arranged on the inner surface, facing to the first cavity, of the solid insulating part; at least a part of the transmission part extends from the cavity to the outside through the avoidance opening; the transmission part can move under the drive of a driving mechanism; the annular dynamic sealing part is arranged on the end plane of the first end of the solid insulating part; the outer circumferential edge of the annular dynamic sealing part is connected with the end plane of the first end of the solid insulating part; and the inner circumferential edge of the annular dynamic sealing part is fixedly connected with the transmission part. The problem of poor insulating performance and poor sealing performance of the circuit breaking apparatus in the prior is solved by the circuit breaking apparatus provided by the invention.

Description

technical field [0001] The invention relates to the field of high-voltage electrical equipment, in particular to a circuit breaker. Background technique [0002] The circuit breaking device is used to cut off or close the no-load current and load current in the circuit, or protect the circuit by cutting off the load current and the breaking current when the system fails. [0003] The existing 35kV circuit breaker is mainly based on gas insulation. The circuit breaker has a large volume, high processing costs, complex processing procedures and maintenance and testing procedures, and the exposed live structure of the circuit breaker is easily corroded and causes insulation failure. , when the staff accidentally touches the surface of the circuit breaker, it is easy to cause electric shock and casualties; not only that, the use of gas-insulated circuit breakers also requires high sealing performance of the circuit breaker, because the gas-insulated circuit breaker is Afterward...
