Problems solved by technology

[0002] There are the following deficiencies in the conduction test of the converter valve in the ice-melting system of the converter station: 1. Due to the design of the manufacturer, the current wiring needs to be manually wired with a clamp, and the test voltage is 220V. 2. The yellow-green grounding wire is currently used for the test wiring, which does not meet the test wiring requirements and the wiring is not beautiful, which may easily cause the test line to break and wind.

Abstract

The invention discloses a convertor station ice melting system converter valve low-voltage trigger test instrument which comprises an oscilloscope with an isolation power module, a resistor with the omega being 500W, a circuit breaker with the alternating current being 220V and 10A or above and two clamps for experiments. When the instrument is in use, a power plug is connected, designed special test handle valve each-stage power-up is adopted, and lamp and oscilloscope waveforms of an observation protection cabinet can be observed. A special tool is used for performing converter valve connection testing work, personal safety can be ensured, the valve working state can be efficiently judged, it is ensured that the site is standard and orderly, and rapid, efficient and standard converter valve connection testing operation is achieved.

Description

technical field [0001] The invention relates to the technical field of converter stations, in particular to a low-voltage trigger tester for converter valves of the deicing system of the converter station. Background technique [0002] There are the following deficiencies in the conduction test of the converter valve in the ice-melting system of the converter station: 1. Due to the design of the manufacturer, the current wiring needs to be manually wired with a clamp, and the test voltage is 220V. 2. The yellow-green grounding wire is currently used for the test wiring, which does not meet the test wiring requirements and the wiring is not beautiful, which may easily cause the test line to break and wind. Contents of the invention [0003] In view of the defects in the prior art, the present invention is dedicated to providing a low-pressure trigger tester for converter valves in the deicing system of converter stations, so as to reduce the dependence on labor and increase...
