Abstract

The invention discloses a circuit breaker plum blossom contact detaching device which comprises a transverse pressing rod. The left end of the transverse pressing rod is provided with a force application hole in a diameter direction. A force application rod is movably arranged in the force application hole. The right end of the transverse pressing rod is provided with a tapered rod. The transverse pressing rod is in threaded connection with a supporting base. The external surface of the supporting base is provided with a holding rod. A spacing member is arranged at the right end of the transverse pressing rod at a position which is next to the tapered rod. The spacing member is arranged at the right side of the supporting base. The right end of the supporting base is connected with an expanding member through a connecting rod. The circuit breaker plum blossom contact detaching device has advantages of simple and compact structure, high convenience and labor saving in operation, and high applicability. The circuit breaker plum blossom contact detaching device can be operated by one person in a narrow space. Maintenance efficiency and replacing efficiency of the circuit breaker plum blossom contact can be greatly improved. Operation safety of an electric power system is improved, and furthermore maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit breaker maintenance, in particular to a circuit breaker tulip contact disassembly device. Background technique [0002] The circuit breaker is the main power control equipment in power plants and substations. It has arc extinguishing characteristics. When the system is operating normally, it can cut off and connect the lines and the no-load and load currents of various electrical equipment; when the system fails , it cooperates with the relay protection to cut off the fault current quickly to prevent the expansion of the scope of the accident. Therefore, the quality of the circuit breaker directly affects the safe operation of the power system. Regardless of the state of the power line, such as no-load, load or short-circuit fault, when the circuit breaker is required to act, it can reliably act, close or cut off the circuit. Circuit breakers are capable of breaking, closing and breaking specifi...
