Problems solved by technology

However, usually high-amplitude shock generators are bulky and cannot be moved, making it impossible to conduct field tests on electrical equipment. This problem can be solved by using a portable compact field shock test generator
At the same time, when using the portable compact field impact test generator for field tests, the interface of the portable compact field shock test generator does not match the GIS interface.

Abstract

The invention discloses an adapter substitute device of a portable on-site gas insulated substation (GIS) impulse test generator. The device comprises a bolt (3), a blind flange (4), an impulse voltage generator input electrically connecting bayonet (5), a basin type insulator (6) with air holes, a case (7), a hollow cylinder aluminum high voltage conductor (8), a 110kVGIS output electrically connecting bayonet (9), a 110kV conductor telescopic arm (10), a 220kV conductor telescopic arm (11), a 220kVGIS output electrically connecting bayonet (12), a spherical connecting body (13), a 500kV conductor telescopic arm (14) and a 500kVGIS output electrically connecting bayonet (15). The device has the remarkable advantages that on-site butt joint of the portable compact type on-site impulse generator is convenient to achieve, the structure is compact, the size is small, the different voltage grades can be switched, and the like.

Description

technical field [0001] The invention belongs to the field of on-site impact test of GIS equipment, in particular, it is suitable for a portable compact on-site impact test generator to be applied in the field of on-site impact test. Background technique [0002] On-site impact tests (including lightning impact, operation impact and fast transient overvoltage) of power equipment such as GIS (Gas Insulated Switchgear) can timely and accurately detect equipment insulation problems and carry out maintenance, which is the key to preventing major power equipment accidents. One of the effective means of accidents. However, usually high-amplitude shock generators are bulky and cannot be moved, making it impossible to conduct field tests on electrical equipment. Using a portable compact field shock test generator can solve this problem. At the same time, when the portable compact field impact test generator is used for field tests, the interface of the portable compact field impact ...
