Abstract

The invention discloses a disconnecting switch and a disassembling method of the contact fingers of the disconnecting switch. The fixed contact of the disconnecting switch includes a contact bracket as well as an upper contact finger and a lower contact finger which are arranged on the contact bracket; the contact bracket is a U-shaped plate; the contact bracket comprises an upper transverse plate, a lower transverse plate and a vertical plate which is connected with the same side edge of the upper transverse plate and the lower transverse plate; each contact finger comprises a main body plate; one end of the main body plate is bent; the other end of the main body plate is flatly straight; the flatly straight end of the main body plate is provided with two second limiting grooves; the front side and the back side of the main body plate are respectively provided with a first limiting groove; the flatly straight ends of the upper contact finger and the lower contact finger are inserted in the U-shaped cavity of the contact bracket; and the bent ends of the upper contact finger and the lower contact finger extend towards opposite directions. The disassembling method of the invention is used for disassembling the contact fingers of the disconnecting switch. According to the disconnecting switch and the disassembling method of the invention, the contact fingers are clamped to the contact bracket, namely, reliable connection of the contact fingers and the contact bracket can be ensured, and when the contact fingers are disassembled, the springs of the contact fingers are not needed to be bent down, and therefore, the springs can be prevented from being ejected out, and disassembly is convenient.

Description

technical field [0001] The invention relates to a dismantling method of an isolating switch and its contact fingers. Background technique [0002] Due to the frequent opening and closing of the existing isolating switch, the moving contact will wear on the static contact, especially the contact fingers on the static contact will be greatly worn. When the wear is serious, it will affect the suction of the moving contact and the static contact. Compatibility, affecting the safety of line operation. Therefore, the isolating switch needs to be overhauled to the isolating switch at regular intervals, especially the contact fingers, which need to be removed from the isolating switch for maintenance. The contact fingers of the existing isolating switch are not easy to disassemble. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide an isolating switch whose contact fingers are easy to disassemble, and to provide a meth...
