GIS equipment and transformer direct connecting device and transformer station using same

Abstract

The invention relates to a GIS equipment and transformer direct connecting device and a transformer station using same; the GIS equipment and transformer direct connecting device comprises an outer cylinder extending in an up-down direction; a connecting conductor conductively connecting a static contact on a transformer sleeve with a bus of the GIS equipment is arranged in the outer cylinder; the outer cylinder comprises an upper cylinder arranged outside the connecting conductor, and a lower cylinder fixedly assembled with the transformer sleeve and arranged outside the transformer sleeve; the upper and lower cylinders are mutually insulated and tightly assembled in one piece; the upper and lower cylinder can ensure the direct connecting device to normally work, thus providing corresponding insulation protection; the upper and lower cylinders are mutually insulated, thus effectively preventing induction currents and hot currents on the GIS equipment from being transferred to the transformer, and causing accident interferences.

Description

technical field [0001] The invention relates to a device for directly connecting GIS equipment with a transformer and a substation using the device. Background technique [0002] With the rapid development of GIS technology, the application of gas insulated substation is becoming more and more extensive. Gas-insulated substations include gas-insulated metal-enclosed switches (GIS) and corresponding power substations. Overhead wires are set between the corresponding bus bars of the GIS and the corresponding terminals of the oil and gas bushings of the substation to realize the corresponding connection between the bus bar and the transformer. However, in areas with high voltage, severe pollution, and high altitude, the connection method of the casing overhead pipeline is greatly affected by external factors, which is not conducive to the normal operation of the substation. [0003] In order to solve the above problems, the direct connection device between GIS and transformer ...

AI Technical Summary

Problems solved by technology

[0004] For direct-connection devices, the integral metal casing of the transformer and GIS switchgear can be in accordance with the corresponding national standards. However, for the 800kV class GIS, there is no corresponding standard, and corresponding product technical parameters and engineering needs need to be corresponded.
