Introduction

DC switch is HVDC transmission system, an important device. In China, the HVDC technology is developing rapidly, and that the existing national Home standards, international standards, were not involved in the content of high voltage DC switch for the high pressure and UHV DC transmission system with open-DC converter Off the design, manufacture, testing has followed an urgent need to develop national standards for high-voltage DC switch. Technical conditions and testing requirements of this standard DC switch is proposed based on the relevant ± 800kV voltage DC transmission system DC converter and with reference to scientific conclusions switch abroad HVDC DC switch design, operation and system test experience Given. HVDC switch
