Installation of 6500MVAshort-circuitgenerator
Two units of 3200MVA short-circuit generators and 220kV power grid are used as the testpower supply of the project (phase one equipped with one unit), Main test capacity as follows:
1.Short-circuitOn-Off type 1 – type 5 test andcapacitive conjunction test of disconnector 6.9-40.5kV
2.Capacitive current On-Off test
3.Rack breaking capacity test inside switch cubicle 40.5kV and below grade, and internal fault test;
4.Short-circuit On-Off testof fuse 40.5kV and below grade. Max. 40.5kV/16kA; 24kV/25kA; 12kV/63kA;
5.General load switch and load switch – fuse combined On-Off and breaking test: rated current 5-2000A, voltage 6.9-40.5kV;
6.Thermal stability test
7.Short-circuit test of transformer:
8.Insulating capability test
