Abstract

The invention provides a discharging assembly which comprises two contact electrodes and a discharging and electricity testing device, and one ends of the two contact electrodes are used for making contact with two electrodes of a to-be-discharged body respectively; the electricity discharging and testing device comprises a discharging resistor R1 and an electricity testing loop, and the two ends of the discharging resistor R1 are electrically connected with the other ends of the two contact electrodes respectively; and the electricity testing loop and the discharge resistor R1 are arranged in parallel, and the electricity testing loop is used for detecting whether the discharge of the to-be-discharged body is completed or not. The problem that in the prior art, workers cannot accurately judge whether discharging of the voltage in the flexible direct current converter valve is completed or not, and safe work of the workers is not facilitated is solved.

Description

technical field [0001] The present invention relates to the technical field of discharge equipment, in particular to a discharge assembly. Background technique [0002] As the world's resources become increasingly tense, new energy power generation is widely used, and flexible DC technology has emerged. Among them, flexible DC converter valves are widely used in flexible DC converter stations, because there are hundreds of capacitors inside, even if the flexible DC The external power supply of the DC converter valve is disconnected, and the internal resistance is used for discharge. There is still a large internal voltage within a short period of time, which makes it impossible for the staff to accurately judge whether the voltage inside the flexible DC converter valve has been discharged, which is not conducive to the safety of the staff. commence to work. Contents of the invention [0003] The main purpose of the present invention is to provide a discharge assembly to s...
