Current and voltage boosting test system for EHV (extra-high voltage) DC ice-melting device

Abstract

The invention discloses a flow-boosting test system for an UHV DC ice-melting device, which includes an overload protection period, the output end of the overload protector is connected to the input end of a multi-phase voltage regulator, and the output end of the multi-phase voltage regulator Connected to the input end of the first converter, the output end of the first converter is connected to the input end of the boost selector and the boost selector, and the output end of the boost selector is connected to the first booster and the boost selector. The input terminal of the second up-flow converter. In the present invention, the system can adjust the current and voltage input to the experimental output box through the boost regulator and the boost regulator; When damaged, the selector can be used to select a spare device to replace it. When repairing the equipment in the system, the entire system will not be paralyzed and cannot be used; the system is equipped with a heat dissipation device to increase its heat dissipation performance and slow down the aging of electrical appliances due to high temperature. speed.

Description

technical field [0001] The invention relates to the technical field of flow boosting test system, in particular to a flow boosting test system for an UHV DC ice-melting device. Background technique [0002] The UHV DC ice-melting device provides an effective ice-melting means for UHV transmission lines to deal with ice disasters. However, due to the actual operation of the UHV DC ice-melting device with the line, the power supply capacity is large, and the UHV transmission line is an important transmission channel. After the UHV DC deicing device is built, it is difficult to use the actual UHV line to carry out commissioning tests, so the design of the UHV DC deicing device test system is an important part of the development of the UHV DC deicing device. Therefore, it is of great theoretical and technical value to carry out research on the flow and boost test system of the UHV DC ice-melting device. [0003] A few universities and scientific research institutes at home and ...

Problems solved by technology

[0003] A few universities and scientific research institutes at home and abroad have conducted research on the current and boost test system of the DC deicing device for transmission lines. The internal booster will generate a large amount of electricity when it is working. If it is not dissipated in time, the components may be damaged, but the whole system cannot be used. For this reason, we have designed a UHV DC ice-melting device to boost the current. Experimental system to solve the above problems
