Abstract
The utility model discloses a permanent magnet operating mechanism which is configured for high and lower voltage switch in a power system. The utility model comprises a T-shaped moving armature; and a closed synchronous incongruous biabsorption and bistable permanent magnet electromagnetic integrated structure composed of a close and open gate loop that are arranged separately inside the upper and lower cavity of the inner magnet yoke, an outer magnet yoke and a permanent magnet.
Description
The utility model relates to a kind of permanent-magnet manipulating mechanism for the configuration of electric power system high and low pressure switch.
In another part of the applicant Chinese patent ZL00205787.5, a kind of permanent-magnet manipulating mechanism that is called the permanent magnetism retainer was described once, it has the T shape moving armature of two fitting surfaces when adopting a "on" position, and close, sub-coil places epicoele, magnetic shunt hand sub-unit places cavity of resorption, and formation is closed, the synchronous dystopy doublebeat of combined floodgate of sub-coil asymmetric arrangement form closes bistable permanent-magnetism electromagnetic integral structure.
The purpose of this utility model is to provide another kind of movement parts to be similarly T shape moving armature, but close, sub-coil is the permanent-magnet manipulating mechanism of symmetric arrangement version.
The utility model includes outer yoke, inner yoke, permanent magnet, closing coil, switching winding, T shape moving armature, it is characterized in that T shape moving armature and be placed in inner yoke upper and lower cavity interior closing coil, switching winding, permanent magnet are fixed on the synchronous dystopy doublebeat of forming in the middle of outer yoke and the inner yoke of combined floodgate and close bistable permanent-magnetism electromagnetic integral structure.
Cross-section structure schematic diagram when Fig. 1 is the utility model permanent-magnet manipulating mechanism "on" position.
Permanent magnet 3 shown in Figure 1 is fixed in the middle of outer yoke 1 and the inner yoke 3, closing coil 4 and switching winding 5 be placed in formation between outer yoke 1 and the T shape moving armature 6 and be divided into by inner yoke 3 about two chambeies in.
The course of work of the utility model embodiment is: during electronic separating brake, impose on 5 one of switching windings and produce the direction of magnetization transient current consistent with the permanent magnetic field direction, T shape moving armature 6 overcomes combined floodgate permanent magnetism confining force, and its pair fitting surface disconnects simultaneously and threads off to move downward and arrives the separating brake terminal location and rely on permanent magnetism power snap close holding position constant.During electric switch-on, impose on 4 one of closing coils and produce the direction of magnetization transient current consistent with the permanent magnetic field direction, T shape moving armature 6 overcomes separating brake permanent magnetism confining force, and the two fitting surfaces of arrival combined floodgate terminal location that move upward are clapped simultaneously and closed, and rely on permanent magnetism to try hard to keep and hold invariant position.So far, finish a work period.
