Abstract
A permanent-magnet operating mechanism for breaker is composed of casing, top cover, base, electromagnetic coil and guide rod connected to movable iron core. The utility model can ensure that the structure is not changed under the repeated impact action of the movable iron core, ensure the operation of the operating mechanism to be accurate, work is very reliable and the service life is long; the structure is reasonable, the assembly process is simpler, the appearance is attractive and elegant, and the circuit breaker can be applied to switch equipment of various circuit breakers, and the application range is wide. The novel combined type hydraulic cylinder has the advantages of simple and reasonable structure, reliable work, simple assembly process, convenience in maintenance, long service life and the like, has great popularization value, and can generate great economic benefits after popularization and application.
Description
Technical field
The utility model relates to the improvement of operating mechanism in the switchgear, is a kind of breaker permanent-magnet operating mechanism specifically, belongs to operating mechanism technical field in the switchgear.
Background technology
Breaker permanent-magnet operating mechanism in the existing switchgear has different version.Breaker permanent-magnet operating mechanism for example shown in Figure 1 is made of shell 01, loam cake 02, base 03, solenoid 04, moving iron core 05, guide rod 06, static iron core 08, power assistant spring 09 etc., is provided with permanent magnet 010 between static iron core and shell.But the permanent magnet of this breaker permanent-magnet operating mechanism mostly is to adopt adhesive 07 to be bonded between static iron core and the shell, unreasonable structure, after operating mechanism work a period of time, adhesive often produces cracking, causes defectives such as the operating mechanism fault is many, the life-span is short.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, provides that a kind of rational in infrastructure, assembly technology is simple, the breaker permanent-magnet operating mechanism of reliable operation, long service life.
The technical scheme that realizes the utility model purpose is:
This breaker permanent-magnet operating mechanism, constitute by shell, loam cake, base, solenoid, the guide rod of fixedlying connected with moving iron core, be characterized in being provided with in the enclosure the ring-type installation base, the ring-type of static iron core install protruding eaves fall to being contained in installation base above, in the gap between static iron core and installation base permanent magnet is housed, below installation base and static iron core, is fixedly connected with pressing plate.
In order to make transmission and mechanical structure more reasonable, on loam cake, be fixedly connected with the assembling cavity, the assembling cavity in guide rod around power assistant spring is housed, gland is equipped with in the termination of guide rod; Cap outside loam cake and assembling are equipped with above the cavity; Between pressing plate and static iron core, be screwed connection.
The utility model can be selected existing electrical material and technology processing and fabricating for use, implements easily.Columniform moving iron core adopts pure iron to make and fixedlys connected the frictional resistance when reducing action with the guide rod screw thread of the white steel of non-magnetic conduction; Shell, loam cake, base etc. adopt carbon steel to make, and make magnetic circuit that higher permeability and lower eddy current loss be arranged; Permanent magnet is selected high-coercive force rare earth permanent magnetism Nd-Fe-B for use.
The utility model since the ring-type of static iron core install protruding eaves fall to being contained in the ring-type installation base above, in the gap between static iron core and installation base permanent magnet is housed, below installation base and static iron core, be fixedly connected with pressing plate.Therefore, can guarantee that structure does not change under the repeated stock action of moving iron core, guarantee the operating mechanism operation accurately, very reliable, the long service life of working; Simultaneously, power assistant spring is moved to the top of loam cake and is added with outer cap, make structure more reasonable, assembly technology is simple, easy to maintenance, good looking appearance is generous.
The utility model can be applicable in the switchgear of various circuit breakers with after auxiliary body is connected, and range of application is very extensive.Have advantages such as simple and reasonable, reliable operation, assembly technology are simple, easy to maintenance, long service life, have great promotional value, will produce than the large economy benefit after applying.
