Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB /Z 24844-2009 "Technical Specifications for Oil-immersed Shunt Reactors for 1000kV AC Systems", and Compared with GB /Z 24844-2009, the main technical changes are as follows. --- Updated normative references, deleted expired and unquoted standards (see Chapter 2,.2009, 2nd) chapter); --- Added basic parameters of 160Mvar/1000kV and 280Mvar/1000kV shunt reactors (see 5.1); --- Supplemented the relevant parameters of the neutral point insulation level of 1000kV shunt reactor (see 5.2); --- Removed the pressure release value of the 1000kV shunt reactor pressure release device (see 6.6.2 of the.2009 edition); --- Modified 1000kV shunt reactor test project. type test added "end lightning interception impact test"; radio dry The disturbance test is listed as a special test item; the "1.1 times overcurrent test" is changed to "1.05 times overcurrent test; the neutral point is deleted." "Discharge measurement", the "end external pressure test" is modified to "end external pressure test (with partial discharge monitoring)", the neutral point Partial discharge measurements are combined with neutral point external pressure test (see Chapter 7, Chapter 7 of the.2009 edition); --- Revised the requirement for dry gas before oil tanking, and the dew point was changed from "not higher than -40 °C" to "not higher than -50 ° C" (see 8.2.1, 8.2.2 of the.2009 edition); --- Removed the requirement for gas purity of gas-filled transport (see 8.2.2 of.2009 edition). --- Supplemented the insulation level at the head end of the neutral grounding reactor (see A.2.2); --- Revised the rated thermal short-circuit current of the neutral grounding reactor (see A.2.3,.2009 edition of A.2.4); --- Increased the requirements for the rated mechanical short-circuit current of the neutral grounding reactor (see A.2.4); --- Added pilot project for neutral grounding reactor (see A.3).
