Problems solved by technology

The limitations of this technical solution are: 1. Using an optical sensor to sense the position will increase the cost of equipment; 2. The life of the optical sensor is short, which can easily lead to induction failure; 3. The optical sensor can only achieve point positioning, and there is a position deviation , cannot locate the complete face of the switch

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

[0013] As shown in the figure, a disconnector with fracture monitoring includes a switch cabinet 1 , a switch cabinet door 2 , a disconnector 3 , a light source 4 and a rectangular hole 5 . The isolating switch 3 is installed in the switch cabinet 1, and the rotation plane of the isolating switch 3 is parallel to the switch cabinet door 2 when it is opened and closed. The door of the switch cabinet directly in front of the rotating plane is provided with a rectangular hole 5 that coincides with the projection of the isolating switch when it is in the opening and closing positions. Between the position holes 51, there is no bright light at the closing position hole 51; when the isolating switch 3 is opened in place, the isolating switch 3 is completely blocked between the light source 4 and the opening position hole 52, and there is no light ...

Abstract

The invention relates to a disconnecting switch with the gap monitoring function. The disconnecting switch is installed in a switch cabinet. The rotation planes of the disconnecting switch in the switching off and switching on processes are parallel with a door of the switch cabinet. A light source is arranged behind the rotation planes of the disconnecting switch. The door of the switch cabinet in front of the rotation planes of the disconnecting switch is provided with rectangular holes coinciding with the projections, at the switching off and switching on positions, of the disconnecting switch. A monitoring device is simple in structure, convenient to install and maintain and capable of reflecting the state of the disconnecting switch clearly.

Description

technical field [0001] The invention relates to the field of high-voltage isolation, and specifically relates to an isolation switch with fracture monitoring. Background technique [0002] High-voltage isolating switches cannot be operated under load, and are usually used in conjunction with circuit breakers. The mechanism for operating the isolating switch is CS6, JS operating mechanism, etc. Because the mechanism does not directly act on the main shaft of the isolating switch, but the connecting rod is operated indirectly. If the adjustment is not good, the opening or closing of the isolating knife switch will not be in place, which will cause heat or arcing and damage the isolating switch. The closing and opening of the isolating switch are mainly known through the transparent observation window on the door or through the opening and closing instructions. Such observation methods usually have deviations. Patent 200780047764 discloses a method for identifying the switch ...
