Knife switch wire changing device for pressure controller

Abstract

The invention provides a knife switch wire changing device for a pressure controller. The knife switch wire changing device comprises a base, a dustproof mechanism, a fixing mechanism, an energizing mechanism, a clamping mechanism and a safety piece, wherein the dustproof mechanism is clamped and connected with the base; the fixing mechanism is fixedly connected with the base; the energizing mechanism is rotatably connected with the fixing mechanism; the clamping mechanism comprises a bolt, and the bolt is slidably connected with the base; and the safety piece is clamped and connected with thebolt. According to the knife switch wire changing device for the pressure controller provided by the invention, the safety piece is in the shape of a two-end wrench, the two ends of the safety pieceare clamped and connected with the bolt on the fixed base and a bolt on an outgoing line base separately, thus the safety piece is conveniently installed inside a knife switch, and the fixation of a fuse is facilitated by fastening the bolt, thereby preventing the fuse from sliding off; and the knife switch wire changing device for the pressure controller has the advantages of convenient operationand flexible use, and can replace the safety piece quickly.

Description

technical field [0001] The invention relates to the technical field of switch blade wire changing for a pressure controller, in particular to a switch blade wire changing device for a pressure controller. Background technique [0002] Knife switch is a switching device that is mainly used for "isolation of power supply, switching operation, connection and interruption of small current circuits", and has no arc extinguishing function. When the knife switch is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; current switching devices. It is generally used as a high-voltage knife switch, that is, a knife switch with a rated voltage above 1kV. Its working principle and structure are relatively simple, but due to the large amount of use and high requirements for working reliability, it is very important for the design of substations and power plants. Both establishment and safe ope...
