Problems solved by technology

When testing the isolating switch, it is necessary to test all the products after assembly one by one. Since the test static contact 102 is a fixed part and there are no moving parts in the middle, only the main switch blade part 103 is tested. , but when hoisting the main switch knife part 103, its center of gravity needs to be placed just below the test static contact 102, and the steel wire rope 104 of the crane interferes with the twisted wire ring of the static contact rod 122, resulting in the bending of the crane steel wire rope 104 over time , torsion, deformation, broken strands and other situations, burying a huge safety hazard
In addition, when installing and disassembling the product, multiple workers must cooperate with each other to push the product to the correct installation position, which also wastes a lot of manpower and material resources

Embodiment Construction

[0031] The embodiment of isolating switch test stand among the present invention: as Figure 1 to Figure 14 As shown, the test stand is an anti-twist test stand suitable for the factory inspection of GW16-126, 252, 363, and 550 high-voltage AC isolating switches. It is mainly composed of a test platform and a test static contact above it.

[0032] The test platform 19 is the same as the traditional test frame, and every three test platforms 19 form a group for testing the three-phase isolating switch. The test platform 19 includes a test underframe fixed on the ground foundation. The top of the test underframe is provided with a base mounting position for fixing the base of the main switch blade part 22, and the test underframe is directly below the test static contact.

[0033] The test static contact is mainly composed of a fixed frame 6, a vertical wire 4, a ring wire 11 and a static contact rod 13. The fixed frame 6 is made up of fixed rods and fixed plates 8 which are do...

Abstract

The invention discloses an isolating switch test rack and a test static contact thereof. The test static contact comprises a rack and a static contact rod which are parallel up and down and set at intervals, wherein the static contact rod is located under the rack; two ends of the static contact rod are respectively in connection with corresponding ends of the rack through leads; at least one lead at two ends of the static contact rod is a vertical lead extending along a vertical direction. Accordingly, when lifting a main switch portion, two sets of wire ropes for lifting the main switch portion can pass by two sides of the vertical lead, so as to lift the main switch portion to the position directly under the test static contact, i.e., a lead is vertically arranged so as to avoid the wire ropes, thereby avoiding interference with the wire ropes used for lifting the main switch portion.

Description

technical field [0001] The invention relates to a test frame of a disconnector and a test static contact thereof. Background technique [0002] According to the relevant national regulations, the main switch knife of each high-voltage disconnector product must undergo a factory test. In the past, in order to simulate the status of the power station, the test racks were arranged according to the actual situation of the power station. Traditional test racks such as Figures 1 to 3 As shown, it is mainly composed of a test platform 101 and a test static contact 102. The test platform 101 is provided with a clamping position for the base of the main knife part 103 to be installed. The test static contact 102 is directly above the test platform 101. The test static contact 102 is an ordinary static contact, including a fixed frame 121 and a static contact rod 122 arranged in parallel and spaced up and down. The static contact rod 122 is located below the fixed frame 121. The rin...
