Problems solved by technology

[0004] The existing technology also has a similar transformation technology. For example, the Chinese patent document CN 102957104A records a transformation method for the flexible connection structure of the transformer and the GIS power distribution device, which overcomes the difficulty of construction, long period, high cost and large economic loss of the above-mentioned existing technology. To provide a soft connection structure and transformation method for transformers and GIS power distribution devices, but it mainly solves the transformation technology brought about by foundation settlement, and has limitations for the transformation of GIS equipment that is already in operation

Embodiment Construction

[0043] The construction method for technical transformation of GIS ontology equipment includes the following steps:

[0044] Such as figure 1 and 5 As shown, the equipment hanger is fixed: the components on the upper part of the current transformer CT9 at both ends of the circuit breaker 10 are connected and fixed as a whole to form a rigid overall frame structure to prevent the displacement of the upper equipment after the flange equipment is disassembled;

[0045] Such as figure 1 As shown, lifting and fixing: connect the connected overall frame structure with the main girder of the bridge crane above the GIS room, and the bridge crane main girder bears the weight of the rigid overall frame structure;

[0046] Such as figure 2 As shown, the circuit breaker 10 is initially disassembled: disassemble the circuit breaker transmission mechanism box 11 and the circuit breaker operating mechanism 12 and remove them from the equipment. After preliminary disassembly, the lower part...

Abstract

The construction method of technical transformation of GIS body equipment can reduce the scope of technical transformation power outages, shorten the power outage time and construction period, reduce the amount of equipment disassembly and assembly and the difficulty of construction operations, and reduce the risk of operation safety and quality. Using this construction method can be based on each series of GIS body The components that need to be replaced on the equipment are constructed in different positions, which increases the flexibility and convenience of the GIS transformation work.

Description

technical field [0001] The invention relates to the field of power system power transmission and transformation engineering transformation, in particular to a construction method for technical transformation of GIS body equipment. Background technique [0002] GIS (Gas Insulated Metal Enclosed Switchgear) is an important device for controlling power transmission in power systems. The safe and stable operation of GIS equipment is directly related to the operation safety and income of power plants, substations and even power grids. With the overall development of society, the demand for electricity in various regions is increasing day by day, and the requirements for increasing the transmission capacity of power grid lines are also coming. The power transmission capacity of GIS equipment in switch stations and substations also puts forward higher requirements. In recent years, due to the increase of the power transmission capacity of GIS main equipment, large-scale technical ...
