Problems solved by technology

[0003] However, the existing isolating switches still have deficiencies in use. Most of them use gate control in the way of opening and closing the contacts, that is, the height of the upper contact is controlled by the gate to realize the distance between the upper contact and the lower contact. However, after using this method for a period of time, the position of the upper contact will shift due to frequent opening and closing, which will cause adverse effects such as poor contact

Abstract

The invention discloses a guide moving type disconnecting switch. The guide moving type disconnecting switch comprises a top plate and a bottom plate, wherein upper contacts are uniformly fixed at equal intervals to the bottom part of the top plate in a clamping manner; the bottom plate is positioned under the top plate, and lower contacts are uniformly connected at equal intervals to the upper surface of the bottom plate through connecting rods; a transverse guide rail is arranged between the top plate and the bottom plate; an intermediate plate is fixed into the transverse guide rail in a clamping manner; longitudinal guide rails are uniformly arranged at equal intervals on the intermediate plate, and mounting plates are fixed into the longitudinal guide rails by clamping. According to the disconnecting switch, all contacts can be separated and combined, and single contact can also be separated and combined; a plurality of mounting plates are mounted on the intermediate plate which controls the overall separating and combining through the longitudinal guide rails and correspond to the contacts; the positions, on the longitudinal guide plates, of the mounting plates can be adjusted to control the separating and combining of the contacts at secondary positions.

Description

technical field [0001] The invention relates to the technical field of switchgear, in particular to a guided mobile isolating switch. Background technique [0002] The isolating switch is a switching device that is mainly used to "isolate power supply, switch operation, connect and cut off small current circuits", and has no arc extinguishing function. When the isolating 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 device. It is generally used as a high-voltage disconnector, that is, a disconnector 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, establishment and maintenance of substations and power plants. The impact on safe operation is greater. The main feature of the isolating swit...
