Abstract

The invention relates to the technical field of high-voltage electric appliance maintenance, and provides a GIS equipment-based non-power-cut maintenance method, which comprises the following steps of: powering off a first bus, carrying out voltage reduction processing on GIS bus coupler interval equipment to be maintained, and keeping a second bus to operate; respectively disconnecting the first disconnecting link air chamber from the first CT air chamber and the first bus air chamber; the first bus air chamber is inflated to rated pressure, and operation of the first bus is recovered; the second bus is powered off, and GIS equipment is overhauled; in the whole process, at least one bus is always kept in a running state, and after maintenance is carried out, the first bus can keep working, so that reliable power supply of a power station is ensured when GIS equipment is maintained.

Description

technical field [0001] The invention relates to the technical field of overhaul of high-voltage electrical appliances, in particular to an uninterrupted overhaul method based on GIS equipment. Background technique [0002] GIS equipment is widely used in substations because of its compact structure, small footprint, high reliability, and low maintenance. [0003] At present, the technology of GIS equipment used in the plant is outdated, and the GIS insulation basin has not been fully hydraulically tested before leaving the factory. It is uncertain whether it can withstand the pressure difference between the rated pressure and vacuum. When the circuit breaker is replaced or overhauled, both sides of the circuit breaker need to be depressurized, so that both busbars connected to the GIS equipment need to be powered off. [0004] The above-mentioned plan that both busbars need to be powered off during the maintenance was designed when the early GIS equipment left the factory, ...
