Embodiment Construction
[0032] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0033] Specific embodiment 1 of the cable terminal connection device for GIS of the present invention, as Figure 4 to Figure 10 As shown, the cable terminal connection device for GIS includes a cable terminal 1 and a GIS connection conductor 3 conductively connected to the cable terminal 1. The outer sides of the cable terminal 1 and the GIS connection conductor 3 are wrapped by a connecting cylinder. It is troublesome to repeatedly disassemble and assemble during the withstand voltage test. The GIS cylinder body 2 is a split structure, including the GIS cylinder body 2 for assembling the GIS connecting conductor 3 and the cable terminal cylinder 4 for assembling the cable terminal 1. This implementation In the example, the GIS cylinder 2 and the cable terminal cylinder 4 are arranged up and down, and the GIS cylinder 2 and the cable terminal cylinder 4...

The invention provides GIS equipment, a cable terminal connecting device for GIS, and a withstand voltage test method for the GIS equipment. The withstand voltage test method comprises the steps: disassembling a GIS cylinder and a cable terminal cylinder, and carrying out the withstand voltage test of GIS switching equipment through the connection of the GIS cylinder with withstand voltage test equipment. During the withstand voltage test of the GIS switching equipment, a GIS connecting conductor does not need to be disassembled, and only the GIS cylinder and the cable terminal cylinder need to be disassembled and the GIS connecting conductor is disconnected with a cable terminal, and then the withstand voltage test equipment is connected with a GIS withstand voltage test port of the GIS cylinder, and a voltage testing end of the withstand voltage test equipment is connected with the GIS connecting conductor so as to achieve the withstand voltage test of the GIS switching equipment. Moreover, during the withstand voltage test of the GIS switching equipment, only the GIS cylinder needs to be filled with SF6 gas, thereby saving the SF6 gas, and solving a problem of the waste of SF6 gas caused during the withstand voltage test of the GIS equipment in the prior art.
Description
technical field [0001] The invention relates to GIS equipment, a cable terminal connection device for GIS and a withstand voltage test method thereof. Background technique [0002] The cable terminal connection device for GIS is a necessary device for connecting power cables and GIS equipment. Since the on-site withstand voltage test parameters of GIS equipment and power cables are inconsistent, it is necessary to conduct withstand voltage tests on both. The existing connecting barrel for GIS is a whole, and the common pressure test methods are as follows: Figure 1 to Figure 3 shown. When carrying out the withstand voltage test on the cable terminal, the GIS connecting conductor 3 needs to be removed, so that the connecting conductor of the pressure-resistant sleeve 6 and the cable terminal 1 passes through the installation area where the GIS connecting conductor 3 is originally installed and is connected to the cable terminal so as to connect the cable terminal 1 Conduct ...
