Technical Field

[0001] The utility model relates to the field of line testing equipment, in particular to an ultra-high voltage two-wire testing machine. Background Art

[0002] The ultra-high voltage two-wire tester is a device used to test high-voltage lines. It can measure the voltage, current, resistance and other parameters in the two wires of the high-voltage line. The ultra-high voltage two-wire tester consists of two main test components: one is the current sensor and the voltage sensor, and the other is the resistance tester. The current sensor and the voltage sensor are usually installed at both ends of the tested wire, and the parameters are measured by sensing the fluctuations of current and voltage. The core of the current sensor is a highly sensitive current transformer that can detect tiny current fluctuations in the wire; the voltage sensor is a high-precision voltmeter that can measure the voltage fluctuations on the wire.

[0003] When testing an ultra-high voltage line, it is necessary to connect the output end and the plug of the ultra-high voltage line to the test socket to test the high voltage line. However, when the plug is inserted into the test socket and the test is being carried out, if the high voltage line is pulled by the outside world, the plug and the test socket may become loose, resulting in inaccurate test data. The plug may also detach from the test socket, affecting the test operation.

[0004] Therefore, it is necessary to provide a new ultra-high voltage two-wire tester to solve the above technical problems. Utility Model Content
