Description
Technical field
The utility model relates to electric machinery field more particularly to a kind of low power consuming shunt release knots for breaker
Structure.
Background technique
Universal shunt release completes the auxiliary element remotely controlled as electrical switchgears such as breakers, is a kind of
Use voltage source as the movement executive device of excitation.However, existing all kinds of intelligent electrical apparatus releases be not able to satisfy sometimes it is different specified
The Matching and selection of current capacity specification when buckle releaser cooperates engineer application Model Selection Scheme, often encounters because of built-in buckle releaser
The problems such as installation space does not adapt to, and buckle releaser output driving kinetic energy is unable to satisfy mating breaker demand, so as to cause can not
Matching and selection is completed according to Practical Project.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of low consumption for breaker is provided
Energy shunt release structure, which is designed by energy-storaging spring structure, not only small in size, but also it is low to consume energy, to solve de-
Detain the not applicable problem of device.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: low power consuming shunt opening for breaker
Tripper structure, it is characterised in that: include end cap, fixed core, electromagnetic coil, dynamic iron core, permanent magnet, gasket, spring, card
Catching groove；The end cap is disc-shaped structure, which is welded with fixed core on one side；The fixed core is hollow cylindrical structure, should
It is divided into inner cavity and exocoel two parts inside fixed core, another side corresponding with inner cavity is provided with umbo outside hollow circuit cylinder
Structure, the evagination diameter of movement is smaller than inner cavity, and is connected between inner cavity；Outer in the fixed core intracavitary is equipped with electromagnetic wire
Circle；The fixed core it is interior it is intracavitary dynamic iron core is installed, which is divided into two parts, is stuck in fixed core inner cavity respectively
Frustum cone structure and the transmission rod extended out by male structure outside fixed core；It is bonded and mats formation at the corresponding dynamic iron core bottom surface of the end cap
There is permanent magnet, which is equipped with gasket, is equipped with the spring connecting with dynamic iron core on gasket；The fixed core
The buckle slot of a circle indent is provided on outer male structure outer wall.
Preferably, spring cavity is provided in the middle part of the dynamic iron core, and the frustum cone structure of dynamic iron core is magnetizer, and power transmission
Bar is non-magnetizer.
The beneficial effects of the utility model are: the structure is designed by energy-storaging spring structure, it is not only small in size, but also consume energy
It is low, to solve the problems, such as that buckle releaser is not applicable.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is tripper structure schematic diagram, and Fig. 2 is dynamic iron core sectional view
Wherein: 1 is end cap, and 2 be fixed core, and 3 be electromagnetic coil, and 4 be dynamic iron core, and 5 be permanent magnet, and 6 be gasket, and 7 are
Spring, 8 be buckle slot, and 4-1 is spring cavity, 4-2 magnetizer, 4-3 non-magnetizer.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of low power consuming shunt release structure for breaker, it is characterised in that: include end cap
1, fixed core 2, electromagnetic coil 3, dynamic iron core 4, permanent magnet 5, gasket 6, spring 7, buckle slot 8；The end cap 1 is disc knot
Structure, the end cap 1 are welded with fixed core 2 on one side；The fixed core 2 is hollow cylindrical structure, is divided into inside the fixed core 2 interior
Chamber and exocoel two parts, another side corresponding with inner cavity are provided with male structure outside hollow circuit cylinder, in the evagination diameter of movement ratio
Chamber is small, and is connected between inner cavity；Outer in the fixed core 2 intracavitary is equipped with electromagnetic coil 3；The fixed core 2 it is interior
Intracavitary to be equipped with dynamic iron core 4, which divides for two parts, is the frustum cone structure being stuck in 2 inner cavity of fixed core respectively and passes through
The transmission rod that the outer male structure of fixed core 2 extends out；Fitting, which is mated formation, at corresponding dynamic 4 bottom surface of iron core of the end cap 1 permanent magnet
5, which is equipped with gasket 6, is equipped with the spring 7 connecting with dynamic iron core 4 on gasket 6；Outside the fixed core 2
The buckle slot 8 of a circle indent is provided on male structure outer wall.
When it is implemented, being provided with spring cavity 4-1 in the middle part of the dynamic iron core 4, and the frustum cone structure of dynamic iron core 4 is magnetizer
4-2, and transmission rod is non-magnetizer 4-3.
When practical operation, under external force, the energy storage trip spring 6 for being built in dynamic 4 spring cavity 4-1 of iron core is compressed
Afterwards, the part magnetizer 4-2 of dynamic iron core 4 will be sucked after being sufficiently close together magnetic yoke by permanent magnet 5, and permanent magnet 5 can provide one
A constant magnetic flux.4 stress of dynamic iron core after dynamic iron core 4 is sucked by permanent magnet 5, before maintaining spring 7 to discharge by permanent magnetic
In balanced steady state.Then make to be offset by moving the permanent-magnetic field in iron core 4 by electromagnetic field components by means of electromagnetic forces,
To make iron core 4 lose the balance between attraction of permanent magnet and the compression release elastic force of energy-stored spring 7, compressed spring is then completed
7 autonomous release and the output of 4 mechanical kinetic energy of dynamic iron core.
