Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly, in particular to a plum blossom contact disassembly and assembly device. Background Art

[0002] Circuit breakers are the main power control equipment in power plants and substations. They have arc extinguishing characteristics. When the system is operating normally, they can cut off and connect the no-load and load currents of the lines and various electrical equipment; when a system fault occurs, it cooperates with the relay protection to quickly cut off the fault current to prevent the scope of the accident from expanding. Therefore, the performance of the circuit breaker directly affects the safe operation of the power system. No matter what state the power line is in, such as no-load, load or short-circuit fault, when the circuit breaker is required to operate, it can reliably operate and close or cut off the circuit. The circuit breaker can open, close and open the specified abnormal current, such as overload current and short-circuit current. Circuit breakers play three roles in the power grid: first, according to the needs of the power grid operation, the circuit breaker has a control function, and the circuit breaker puts some power equipment or lines into or out of operation; second, when a power line or equipment fails, the circuit breaker quickly cuts off the faulty part from the power grid to ensure the normal operation of the fault-free part of the power grid, which has a protective effect; third, the circuit breaker can isolate the maintenance equipment or installation equipment from the high-voltage power supply, which has a safety isolation function and ensures the safety of the maintenance and installation personnel and equipment.

[0003] Because circuit breakers play such an important role in the power system, and the excessive power load of the power grid may cause the plum blossom contacts of the circuit breaker to heat up due to poor contact. If not handled in time, the clamping force of the plum blossom contact spring of the circuit breaker will continue to decrease, which will cause the contact resistance of the moving and static contacts on the circuit breaker to continue to increase, further causing the plum blossom contacts of the circuit breaker to heat up and burn, and even explode. Therefore, timely inspection and replacement of the plum blossom contacts of the circuit breaker is an important guarantee to ensure the safe operation of the power system.

[0004] However, when repairing or replacing the plum blossom contacts of the circuit breaker, a plum blossom contact disassembly and assembly device is usually used to disassemble and assemble the plum blossom contacts. However, the range of the existing plum blossom contact disassembly and assembly device is within a certain fixed range, which makes it difficult to disassemble and assemble plum blossom contacts of various sizes, which has limitations. Therefore, a plum blossom contact disassembly and assembly device is invented. Utility Model Content
