Power operation test device suitable for flexible direct current transmission converter valve submodule

Abstract

The invention discloses a power operation test device suitable for a flexible DC power transmission converter valve submodule, and the device comprises a test equipment body, the two sides of the test equipment body are provided with heat dissipation holes, and the interior of the test equipment body is provided with a rotary opening and closing heat dissipation mechanism.The invention relates to the technical field of DC. By arranging the rotary opening and closing heat dissipation mechanism, when a rotary plate rotates to keep a vertical state, sealed air at the top of the test equipment body is opened, so that the test equipment body can be communicated with air outside the test equipment body through the top, and heat exchange and heat dissipation are carried out on the interior of the test equipment body; and the heat dissipation channel at the top of the test equipment body is automatically opened for heat dissipation when the temperature in the test equipment body rises, and the heat dissipation channel at the top of the test equipment body is not opened at the normal heat dissipation temperature, so that the dustproof effect in the test equipment body is kept.

Description

technical field [0001] The invention relates to the field of direct current technology, in particular to a power operation test device suitable for a sub-module of a flexible direct current transmission converter valve. Background technique [0002] "Direct current", also known as "constant current", constant current is a kind of direct current, which is a direct current with constant magnitude and direction. Direct current is the one-way flow or movement of charges, usually electrons. The current density varies with time, but generally the direction of movement is the same at all times. As an adjective, DC can be used for a reference voltage (which never changes polarity). At present, the equipment suitable for the power operation test of the flexible DC power transmission and the converter valve sub-module has a high heat generation, and requires manual real-time monitoring under high-load work, and it is impossible to intelligently and automatically perform targeted heat...

AI Technical Summary

Problems solved by technology

At present, the equipment suitable for flexible direct current transmission and the power operation test of the converter valve sub-module has a high calorific value. It needs manual real-time monitoring under high load work, and it is impossible to intelligently and automatically adjust the heat dissipation in a targeted manner.
