Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as Figure 2-5 As shown, the vacuum interrupter dynamic and static contact surface purification system includes a DC arc welding machine that provides two-pole purification power supply, a programmable logic controller, a relay, and a contact surface purification system. Both the programmable controller and the relay are connected with the contact surface purification system, and the mechanism action of the contact surface purification system is completed by the program drive of the programmable controller and the relay. The mechanical parts of the entire contact surface cleaning system are supported by the skeleton table 1 . The contact surface purification system includes a skeleton table panel 1 supporting the entire contact surface purification system, a stretching cylinder 3, a stretching cylinder rod 21, a moving co...

Abstract

The invention discloses a surface decontamination system for moving and static contacts of a vacuum arc extinguish chamber, comprising a stretching cylinder, a stretching cylinder rod, a moving conducting rod, a lift cylinder, a lift cylinder rod, a fixed contact rod electrode sleeve, a first electrode terminal and a second electrode terminal, wherein the stretching cylinder is connected with the stretching cylinder rod, the stretching cylinder is operated to drive the stretching cylinder rod to vertically lift, the upper end of the stretching cylinder rod is connected with the moving conducting rod; the lift cylinder is connected with the lower end of the lift cylinder rod and drives the lift cylinder rod to vertically lift, the lift cylinder rod is connected with the fixed contact rod electrode sleeve and drives the fixed contact rod electrode sleeve to move up and down; and one pole of a direct current arc welder power supply is connected with the first electrode terminal, the other pole is connected with the second electrode terminal, the first electrode terminal is connected with the moving conducting rod, and the second electrode terminal is connected with the fixed contact rod electrode sleeve. The invention realizes the advantages of high decontamination efficiency, uniform decontamination of surface ablation of the moving and static contacts of a vacuum switching tube and good consistency.

Description

technical field [0001] The invention relates to a purification system, in particular to a surface purification system of a dynamic and static contact of a vacuum interrupter. Background technique [0002] At present, the vacuum switching tube is purified by using the manual operation method of separating and closing the dynamic and static contacts by using the principle of leverage. Such as figure 1 as shown, figure 1 It is a schematic diagram of the moving and static contacts of the switching tube after being pulled apart. The switching tube shown in the figure includes the static contact and the moving contact set on the switching tube, and the end faces are the surface of the static end contact and the moving end contact respectively. Surface, the surface of the static end contact and the surface of the moving end contact are in contact at ordinary times. There is also a shielding tube on the periphery of the static contact and the moving contact. There is also a bello...
