Method for disassembling and assembling plum blossom contact of circuit breaker of centrally installed switchgear

The invention relates to the technical field of plum blossom contact disassembly and assembly, in particular to a centrally installed switchgear circuit breaker plum blossom contact disassembly and assembly method, which comprises the following steps of: operating a manual hydraulic cylinder to repeatedly pressurize, moving an output rod outwards, pushing a push head outwards to move along a conical slide way in an expansion operating piece, and expanding each expansion head outwards; therefore, the topmost part of the expansion operation part expands the tulip contact outwards. And when the contact finger sheets of the tulip contact are separated from the conductive copper pipe grooves of the circuit breaker, the whole tulip contact can be taken down. The tool is time-saving, labor-saving, light, flexible and easy to operate, can effectively solve the problem that no special dismounting tool exists in the tulip contact overhauling or replacing process, avoids violent dismounting in field operation, timely re
