Abstract

The invention discloses an accident emergency handling method for a switch cabinet. The method comprises the following steps of judging the condition of an emergency maintenance site, wherein the special steps comprises: performing electrical and relay protection tests on isolated equipment, selectively maintaining or replacing the equipment after the electrical relay protection test, performing the electrical and relay protection tests on the replaced equipment, judging whether the equipment is qualified or not, waiting for a command after the equipment is determined to be qualified, and transmitting electric power to the equipment to finish the handling of an failure accident; isolating failing equipment under the condition of an equipment failure accident; seeking reasons for error signal reporting under the condition of error signal reporting, wherein the second step further comprises the following steps of. According to the method, the accident handling reliability can be ensured, and the electric power can be conveniently and quickly recovered.

Description

technical field [0001] The invention relates to a method for emergency treatment of electric power accidents, in particular to a method for emergency treatment of switch cabinet accidents. Background technique [0002] In the prior art, power system accident handling is based on the text of regulations and abstract dispatching experience, which is time-consuming and laborious, and the results are not accurate enough. After an accident, the on-duty personnel dispatched by the substation or the lower level will report the protection action and switch tripping by telephone, and go to the tripping device to manually check the equipment failure. When dealing with accidents, it is also based on the operation mode of the power grid after the accident, the topological structure of the power grid, and the accident handling procedures, etc., manually design a feasible fault recovery plan, and complete the switching operation of the accident handling through remote control or telephone...
