Abstract
A double-coil permanent magnet and electric magnet integrated steady state mechanism comprises an external magnetic cylinder, a permanent magnet, an interior magnetic ring, a closing and tripping coil, a cylindrical iron core and a guide shaft, and is characterized in that a spare tripping coil is arranged at the lower part of the closing and tripping coil. Compared with the prior art, the utility model has the advantages of simple and compact structure, low product cost, stable operation, safety and reliability. When the closing and tripping coil is burned down and the spare tripping coil can be started to instantly realize power tripping of a circuit breaker in a tripping state via the forward current of a DC screen power supply, thereby reducing danger caused by manual tripping and enhancing safety and reliability of the mechanism.
Description
Technical field
The present invention relates to electric power system for the distribution field, relate in particular to a kind of a kind ofization of twin coil permanent-magnetism electromagnetic steady state mechanism of high-voltage switch gear.
Background technology
The permanent magnet mechanism of the used for high-voltage switch of Chu Xianing in recent years, it is simple in structure, and parts are few, and the reliability advantages of higher successfully is applied in the electric power system high-voltage switch gear.At present, the version of permanent magnet mechanism just develops towards diversified direction, and numerous patented technologies has promoted the permanent magnet mechanism technical merit to improve constantly, as Chinese patent; Dozens of patents such as ZL20042008409X, ZL00205785.5, ZL01222529.0.But, still exist not enoughly in the prior art, when move as unicoil mechanism, in case coil burnout just can't the electric power separating brake, if employing manual emergency separating brake, operator and equipment all have certain danger; Two coils are controlled respectively and are closed a floodgate and separating brake, and are in the upper and lower side of mechanism, are unfavorable for the compressing mechanism system, and the excessive copper cash consumption of coil is many, causes cost high.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of twin coil permanent-magnetism electromagnetic integrated steady state mechanism, have simple and compact for structure, advantage such as product cost is low.
The technical solution of the utility model is: the integrated steady state mechanism of a kind of twin coil permanent-magnetism electromagnetic, comprise outer magnetic cylinder, permanent magnet, lining magnet ring, on/off switch coil, cylinder iron core and the axis of guide, it is characterized in that: the below that is positioned at the on/off switch coil is provided with standby switching winding.
The utility model compared with prior art, have simple and compact for structure, product cost is low, stable, safe and reliable, when the on/off switch coil burnout, can start standby switching winding, be in the electronic separating brake of circuit breaker under the "on" position by the instantaneous handle of direct current cabinet power supply forward current,, strengthened advantages such as security reliability to reduce the danger that the mechanism manual separating brake may cause.
Description of drawings
Accompanying drawing is the utility model structural representation; Among the figure
Magnet ring 4-cylinder iron core in the outer magnetic cylinder 2-permanent magnet 3-of 1-
The standby switching winding of 5-axis of guide 6-on/off switch coil 7-
S, N-permanent magnet pole.
Embodiment
Now, the utility model is further described as follows by accompanying drawing and in conjunction with embodiment:
Embodiment
From accompanying drawing as seen, the integrated steady state mechanism of a kind of twin coil permanent-magnetism electromagnetic of the utility model, comprise outer magnetic cylinder 1, permanent magnet 2, lining magnet ring 3, on/off switch coil 6, cylinder iron core 4 and the axis of guide 5, it is characterized in that: the below that is positioned at on/off switch coil 6 is provided with standby switching winding 7.
Accompanying drawing is the integrated steady state mechanism structural representation of the utility model twin coil permanent-magnetism electromagnetic, and represents the operation principle of its on/off switch state.From this figure as seen, in magnet ring 3 and outer magnetic cylinder 1 compulsory linking together, permanent magnet 2 is arranged and is fixed between outer magnetic cylinder 1 and the lining magnet ring 3 by N, the S utmost point successively, is on/off switch coil 6 below permanent magnet 2, lining magnet ring 3, is newly-installed standby switching winding 7 below on/off switch coil 6; Cylinder iron core 4 is connected as a single entity with the axis of guide 5, and parallel motion up and down under the guiding of the axis of guide 5.The integrated steady state mechanism of a kind of twin coil permanent-magnetism electromagnetic of the utility model, when being in course of normal operation, electronic separating brake is applied to switching winding 6 and the instantaneous back electric current of serial connection current-limiting resistance is untied combined floodgate magnetic force, makes switch arrival separating brake position and is in stable state under extraneous power (as spring force) effect; During electric switch-on, directly impose on closing coil 6 instantaneous forward currents when overcoming extraneous power, the combined floodgate in-position also is in stable state, thereby finishes an electronic divide-shut brake cycle.When the switching winding that breaks down is burnt, start standby switching winding 7 this moment, make standby switching winding 7 be in the electronic separating brake of circuit breaker under the "on" position by the logical instantaneous handle of forward current of direct current cabinet power supply, can reduce the mechanism manual separating brake like this, thus the danger of avoiding mechanism's separating brake to cause.Then change the on/off switch coil that is burnt, to realize safe operation.
