Abstract

The invention discloses a current and voltage rise testing system for an ultra-high voltage direct-current deicing device. The current and voltage rise testing system comprises an over-current and over-voltage protector, a multi-phase voltage regulator, a current and voltage rise switcher, a pulse current rise transformer, a pulse voltage rise transformer, a current rise test pressure-equalizing device, a voltage rise test pressure-equalizing device and a test voltage output branch box which are organically connected with one another. According to the current and voltage rise testing system, the requirements that the current and voltage rise testing system for the ultra-high voltage direct-current deicing device is high in capacity and is fixedly arranged on a transformer can be met; the test requirements of heavy current and high voltage in debugging of the ultra-high voltage direct-current deicing device can be effectively met; and the reliable, economic and effective current and voltage rise testing system can be provided for the debugging after building of the ultra-high voltage direct-current deicing device.

Description

technical field [0001] The invention relates to a flow-boosting test system for a 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. A few universities and scientific research institutes at home and abroad have conducted research on the current and boost test system of the DC...
