The invention provides a cable terminal testing device, comprising an insulated elastic tester main body. The elastic tester main body is provided with an inner cavity. The inner cavity comprises an insertion cavity suitable for a to-be-tested cable terminal to be inserted in and closely clinging to the to-be-tested cable terminal as well as a through hole communicated with the insertion cavity and suitable for the outgoing and incoming of wires of the to-be-tested cable terminal. When a voltage standing test needs to be done to the to-be-tested cable terminal, the to-be-tested cable terminal is inserted into the inner cavity of the elastic tester main body so that the to-be-tested cable terminal clings to the inner cavity closely and through the wires, the to-be-tested cable terminal is connected with a voltage exerting device so as to perform the voltage standing test. The cable terminal testing device is small in size, convenient to carry and easy to operate.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a cable terminal testing device. Background technique [0002] According to national standards, electrical performance tests must be done when the cable accessories leave the factory, including power frequency withstand voltage and partial discharge tests, to ensure that the electrical performance meets the standard requirements. GIS is a gas-insulated terminal, installed inside the gas-insulated switchgear (GIS), and the cable terminal of the gas-insulated part with sulfur hexafluoride gas as the external insulation. It is also necessary to simulate the internal operating structure of the GIS equipment during the factory test. The terminal is tested for power frequency withstand voltage and partial discharge. [0003] Chinese patent document CN204188754U discloses a 110kV GIS terminal stress cone test device, which can be used for withstand voltage testing of cable term...
