Abstract
The invention relates to a brake separating and tripping structure for the operation mechanism of a circuit breaker, which comprises a swinging plate and a brake separating fan-shaped plate arranged under the swinging plate, and has the innovation point that one end of the brake separating plate is connected with a fixed shaft, and an electromagnetic coil is also connected onto the fixed shaft through a connecting rod. The brake separating fan-shaped plate directly locks and unlocks the swinging plate through being driven by the electromagnetic coil, the secondary tripping is realized without using an electromagnet for driving a half axle to rotate, the half axle damage problem does not exist, and the reliability of the brake separation work is improved.
Description
Technical field
The present invention relates to a kind of breaker operation mechanism, particularly a kind of separating brake releasing structure of breaker operation mechanism.
Background technology
Primary cut-out is the main electric control appliance of power plant, electric substation, has arc quenching characteristic, and when system normally moved, it can cut off and connect the zero load and the load current of circuit and various electric equipments; When system broke down, it and relaying protection cooperated, and energy is the disengagement failure electric current rapidly, to prevent expansion accident scope.
The operating mechanism of primary cut-out is a kind of annex of far distance automatic separating brake and combined floodgate circuit breaker, its separating brake tripping mechanism mainly comprises the oscillating deck that is connected with the arc-extinguishing chamber of circuit breaker pull bar by connecting rod, be located at the separating brake fanning strip of oscillating deck below, one end of separating brake fanning strip is fixed on the mounting panel by axle, the other end is provided with claw, claw one side is provided with semiaxis, and semiaxis is rotated by solenoid actuated.During to the tripping spring accumulation of energy, utilize claw to fasten semiaxis and realize accumulation of energy, when needing separating brake, rotated to an angle by the solenoid actuated semiaxis, claw is threaded off, and tripping spring drives the separating brake fanning strip and rotates the realization separating brake.The shortcoming of this kind structure is: semiaxis is very easily machined away one jiao by claw and causes damage, and the reliable operation performance reduces.
Summary of the invention
The technical problem to be solved in the present invention provides the separating brake releasing structure of the high breaker operation mechanism of a kind of functional reliability.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of separating brake releasing structure of breaker operation mechanism, comprise oscillating deck, be located at the separating brake fanning strip of oscillating deck below, its innovative point is: an end of described separating brake fanning strip is connected with fixed axis, also is connected with solenoid by connecting rod on the described fixed axis.
The invention has the advantages that: the separating brake fanning strip is directly driven by solenoid and pins and throw off oscillating deck, need not to use the solenoid actuated semiaxis to rotate to realize secondary to thread off, and does not exist semiaxis to damage problem, has improved the reliability of separating brake work.
Description of drawings
Accompanying drawing is the separating brake releasing structure schematic diagram of breaker operation mechanism of the present invention.
Embodiment
As shown in drawings, the present invention relates to the separating brake releasing structure of the high breaker operation mechanism of a kind of functional reliability, comprise oscillating deck 1, be located at the separating brake fanning strip 2 of oscillating deck 1 below, end at separating brake fanning strip 2 is connected with fixed axis 3, also is connected with solenoid 5 by connecting rod 4 on the fixed axis 3.Separating brake fanning strip 2 is directly pinned by solenoid 5 drivings and throws off oscillating deck 1, need not to use the solenoid actuated semiaxis to rotate and realizes the secondary dropout, has improved the reliability of separating brake work.
Claims (1)
1. the separating brake releasing structure of a breaker operation mechanism comprises oscillating deck, is located at the separating brake fanning strip of oscillating deck below, and it is characterized in that: an end of described separating brake fanning strip is connected with fixed axis, also is connected with solenoid by connecting rod on the described fixed axis.
