Scope

GB/T 37008-2018 is the English-translated version of 柔性直流输电用电抗器技术规范.

GB/T 37008-2018 is the technical specification for the reactors used in flexible DC (VSC-HVDC) transmission. It covers dry-type air-core bridge arm reactors connected to modular multilevel voltage source converters, in both symmetrical monopole and bipolar systems.

The document sets out terms, symbols and the product model designation, the conditions of use, and the technical requirements, including the temperature rise limits for the windings, metal structures and terminals.

It then lists the routine, type and special tests with their test methods, and closes with the nameplate and with lifting, marking, packaging, transport and storage.

It builds on the GB/T 1094 series for power transformers and reactors and on GB/T 25092-2010. It was issued on 28 December 2018 and has applied since 1 July 2019.

GB/T 1094.6, GB/T 1094.11, GB/T 25092-2010 and GB/T 37011 as defined in the following terms and definitions Applicable to this document.

3.1 Bridge arm reactor

A reactor connected in series on the bridge of the voltage source converter.

Note 1. The current flowing under normal conditions consists of DC bias current, power frequency current and superimposed harmonic current, which mainly suppresses the circulation and suppression between the bridge arms. The effect of the bridge arm fault current rising too fast during a short circuit.

Note 2. In actual engineering projects, the bridge arm reactor may be arranged on the AC side of the inverter or on the DC side of the inverter.

3.2 Rated inductance
