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
1 Scope
This standard specifies the terms and definitions HVDC switch, the use of ambient conditions, ratings, technical requirements, type testing, routine
Tests, special tests, field trials and the like.
This standard applies to ± 800kV and below voltage DC transmission system with DC switch, including Metal Return open
Off the earth loop switch, switch neutral bus and neutral bus grounding switch.
This standard also applies to the transfer switch actuator and its auxiliary equipment.
