Magnetic force operating mechanism used for three-station isolation grounding switch

Abstract

The invention relates to a magnetic force operating mechanism used for a three-station isolation grounding switch, and aims to solve the problem that the magnetic force operating mechanism cannot satisfy the three-station operation requirement in the prior art. The magnetic force operating mechanism used for the three-station isolation grounding switch comprises a mechanism framework and a power output end assembled on the mechanism framework in a guiding and moving manner to be in transmission connection with a body moving end; fixed permanent magnets for forming magnetic field gaps, which extend in the moving direction of the power output end, are arranged in the mechanism framework; electromagnetic coils capable of moving in a reciprocating manner in the extension directions of the magnetic field gaps and connected with the power output end are arranged in the magnetic field gaps; each electromagnetic coil has a first extreme limit position and a second extreme limit position positioned at the two ends in the reciprocating moving travel, and also has a middle position positioned between the first extreme limit position and the second extreme limit position; and the magnetic force operating mechanism also comprises an elastic part for applying acting force to the electromagnetic coils and remaining the electromagnetic coils in the middle positions at the telescopic set length.

Description

technical field [0001] The invention relates to a magnetic force operating mechanism for a three-position isolating grounding switch. Background technique [0002] The operating mechanisms used in the current three-position isolation and grounding switches are mostly traditional operating mechanisms such as electric mechanisms, electric spring mechanisms, and hydraulic mechanisms. In a specific historical period, limited by the level of technological development, the traditional operating mechanisms have its technological advancement. However, with the advancement of science and technology, the disadvantages of traditional mechanisms are gradually revealed. Traditional mechanisms have defects such as complex structures, many types of parts, difficult installation and maintenance, high operating noise, and oil leakage. The value of intelligent transformation. [0003] An invention patent application with application publication date of July 7, 2017 and application publicati...
