GB/T 22382-2008 Direct connection between power transformers and gas-insulated metal-enclosed switchgear for rated voltages of 72.5kV and above (English Version)
This standard specifies the service conditions, ratings, design and structure, test, information provided with inquiries, tenders and orders, transportation, storage, installation, and operation of direct connection devices between gas-insulated metal-enclosed switchgear and power transformers. and maintenance rules, supplier boundaries, etc. This standard applies to the gas-insulated metal-enclosed switchgear that meets the requirements of GB 7674 with a rated voltage of 72.5kV and above and the power transformer that meets the requirements of GB 1094. It is equipped with a transformer that meets the requirements of GB/T 4109, and one end of it is immersed in transformer oil. , the other end of which is a single-phase connection device of a fully immersed bushing in the insulating gas of the switchgear. The purpose of this standard is to establish electrical and mechanical interchangeability with respect to the interface structure of these connection devices and to define supplier boundaries.
