Description

Technical Field

[0001] The present invention relates to the technical field of casing installation, and specifically to an auxiliary connection device for high-voltage power casings. Background Art

[0002] High-voltage casings are mainly used for the ground insulation of the incoming and outgoing lines of power equipment such as transformers, reactors, and circuit breakers, and for high-voltage circuits passing through walls. Their diameters are generally between 50 mm and 300 mm, and their lengths are between 500 mm and 2000 mm. Such products have the defects of high assembly difficulty and high labor intensity during assembly. To solve the above problems, technicians in this field have developed a variety of assembly auxiliary devices. For example, the invention patent technology with the publication number CN109176403A and the name of an in-line device for casing assembly authorized and announced by the China Patent Office on January 11, 2019, is placed inside a hollow composite insulator and includes a first plate body and a second plate body that are parallel to each other and can be disassembled and connected. A first through hole is provided on the first plate body, and a second through hole is provided on the second plate body. The first through hole and the second through hole are coaxially arranged. A plurality of abutting parts are respectively formed on the peripheries of the first plate body and the second plate body.
