Problems solved by technology

[0004] The present invention provides a contact seat to solve the problem that the electric field distribution at the hand hole will be uneven if the hand hole is set on the outer peripheral surface of the fixed part of the contact seat in the prior art, and it is easy to cause the electric field strength here to be too high and be hit. wear problem
The present invention also provides a GIS using a contact seat to solve the problem that in the prior art, setting a hand hole on the outer peripheral surface of the fixed part of the contact seat will lead to uneven distribution of the electric field at the hand hole, which will easily cause the field strength here to be too high And the problem of being broken down

Embodiment 1

[0046] Such as Figure 2-5 As shown, it includes a GIS cylinder 9, and a contact base 1 fixed on the GIS cylinder through a basin insulator 6. The GIS cylinder 9 also has a conductive contact rod in conductive contact with the conductive connection part 12 of the contact base 1. 10.

[0047] Here, the contact holder 1 specifically includes a cylindrical fixing part 11 and a conductive connecting part 12 electrically connected to the corresponding conductor. There is a closed part 111 on the end of the cylindrical fixed part 11 away from the conductive connecting part. On the closed part 111 There are four contact seat fixing holes 5 evenly distributed around the circumference, and the contact seat 1 and the pot insulator 6 in the GIS can be fixedly assembled by setting threaded fasteners in the contact seat fixing holes 5 . In the cylindrical fixing part 11 of the contact base 1, there is an operation cavity for installing threaded fasteners in the fixing hole of the contact ...

Abstract

The invention relates to a contact pedestal and a GIS using the contact pedestal. A circular arc sealing cover for sealing a hand hole is detachably and fixedly assembled at the hand hole; the outer peripheral surface of the circular arc sealing cover is fit with the outer cylinder wall surface of a fixing part; after an operator completes mounting and fixing of the contact pedestal in an operation cavity through the hand hole opened in the cylinder wall of the fixing part of the contact pedestal, the circular arc sealing cover is adopted to seal the hand hole, and thus, after sealing, the outer peripheral surface of the circular arc sealing cover is fit with the outer peripheral surface of the fixing part, the circular arc sealing cover fills the hand hole in the outer peripheral surfaceof the fixing part, the outer peripheral surface of the whole fixing part of the contact pedestal forms a complete circular arc surface, and thus, the problem of over high field intensity to result inbreakdown at the place due to uneven electric field distribution at the hand hole can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of electrical switchgear, and in particular relates to a contact seat and a GIS using the contact seat. Background technique [0002] In the field of electrical equipment, gas-insulated metal-enclosed switchgear (GIS for short) is one of the most important power transmission and distribution equipment, and its operating voltage can reach up to 1100kV. GIS has high requirements for insulation performance. Electric field requirements and disassembly requirements, usually the contact seats in GIS are mostly detachable contact seats. [0003] In the prior art, such as the bus connection device disclosed by the Chinese utility model patent whose authorization announcement number is CN205944753U, such as figure 1 As shown, the busbar connection device includes a first busbar housing 10 and a second busbar housing 30, the first busbar housing 10 and the second busbar housing 30 are respectively provided with a fir...
