Isolation baffle mechanism of bypass switch

Abstract

The invention relates to an isolating baffle mechanism for a bypass switch. The isolating baffle mechanism is of a symmetrical frame structure, and mainly comprises a base plate, a bracket, a crank, a lever, a joint lever, a tension spring 1, an oscillating bar 1, a hinged shaft 1, a tension spring 2, an oscillating bar 2, a hinged shaft 2, a hinged shaft 3, an oscillating bar 3, a tension spring 3, a mounting plate, a hinged shaft 4, a hinged shaft 5, a pushing plate, a connecting rod, a hinged shaft 6, a baffle 1, a baffle 2 and a baffle 3; when a main body switch is pushed in, the pushing plate at the bottom of the main body switch touches the upward front end of the lever firstly, along with the forward moving of the pushing plate, the front end of the lever oscillates downwards under the action of a downward pressing force, the other end of the lever oscillates upwards so as to push the joint lever to move upwards, along with the upward moving of the joint lever, two oscillating bars below the joint lever oscillate upwards, and the upmost oscillating bar moves downwards. Because a force exerted on the lever is far greater than a tensile force of the spring, the baffles move to corresponding directions under the driving of the oscillating bars. The baffle mechanism disclosed by the invention runs smoothly, and the reliability of the baffle mechanism is also greatly improved.

Description

Technical field [0001] The invention belongs to the field of electromechanical manufacturing, and particularly relates to an isolation baffle mechanism of a bypass switch. Background technique [0002] A draw-out type power transfer switch with bypass is mainly composed of a main switch and a bypass switch. The main switch can be drawn and inserted into the box of the bypass switch. The isolation baffle mainly protects the bypass switch: one is to protect personal safety and avoid casualties; the other is to prevent foreign objects from entering and avoid current short-circuits. Damage, fire and other accidents. [0003] When the main switch is inserted, the isolation baffle needs to be opened automatically so that the main switch contact is inserted into the bypass switch contact, the main switch and the bypass switch are connected, and the isolation baffle has no protective effect. When the main switch is pulled out, the isolation baffle closes automatically, the bypass switch ...
