Problems solved by technology
For high-voltage switchgear with a rated voltage of 4000A, the total cross-sectional area of the large-section test output wires connected to each phase busbar during the test reaches 3000mm 2 Above, the length exceeds 2 meters, the weight of these wires plus the weight and leverage of the test busbar, the gravity acting on the insulating sleeve on the side of the switchgear reaches hundreds of kilograms, and the insulating sleeve is of certain hardness and brittleness. Composite materials, during the hours-long test process, are easily damaged by stress, and then destroy their insulation performance, causing accidents after the equipment is put into operation

The invention discloses a busbar support for a 4000 A high-voltage switch cabinet temperature rise test. The busbar support comprises a tested 4000A high-voltage switch cabinet. A plurality of insulating sleeves are fixedly installed on one side of the tested 4000A high-voltage switch cabinet, a test wiring busbar is fixedly installed on one side of each insulating sleeve, a large-current output wire is fixedly installed on one side of each test wiring busbar, and a support is supported at the bottom end of each test wiring busbar. The invention provides a busbar supporting structure for carrying out a 4000A high-voltage switch cabinet temperature rise test in the power industry and preventing sleeve stress damage, a busbar for the test can be stably and effectively supported, and equipment operation accidents caused by stress damage of the busbar connected with a large-current output wire in a hanging manner to an insulating sleeve are prevented. The supporting structure is simple inform, convenient to process, low in cost, convenient to use, small in occupied area, capable of effectively shortening the length of the busbar for the test while ensuring that the test is smoothly carried out, and worthy of popularization and application in similar test occasions.
Description
technical field [0001] The invention relates to the field of high-voltage testing of power grid equipment, in particular to a busbar bracket for temperature rise testing of a 4000A high-voltage switch cabinet. Background technique [0002] Due to the important influence of the power industry on the national economy and society, the reliability of its system operation has strict requirements, and a key link in the reliable operation of the power system is the quality and reliability of power equipment. Before the power project is put into operation and during its operation, various tests must be carried out on its key equipment to verify its reliability. High-voltage switchgear is a kind of power equipment widely used at present. It is a switchgear that undertakes the distribution and control functions of electric energy in the distribution network. It is mainly used for 3-35kV voltage level. Usually, metal cabinets are used to package high-voltage circuit breakers, isolatin...
