Regarding the issue of the transformer oil sump

2020-11-23View Original

Thread Content

Dear experts, which standard specifies the oil storage tank for transformer accidents? Is it necessary to install an accident oil storage tank for an outdoor oil-immersed transformer of 800KW?

You can take a look at GB 50053 and GB 50060

It seems to be related to the amount of oil in the transformer

I have never seen a transformer this small; even the 2000-type oil transformers used 20 years ago didn’t have an oil tank, and the 35 kV 31500-type transformers also lacked one. Only 140 kV transformers come standard with an oil tank.

It’s generally not used; it’s too small.
