Between limiting section 21, to make coil 3 be firmly placed on bobbin 2.
Static iron core 5 is fixedly connected on bobbin 2.Oil cylinder 11 is movably connected in the inside of bobbin 2.Specifically, coil
There is frame 2 through-hole 22, static iron core 5 to be fixedly connected on one end of through-hole 22.
The opening of oil cylinder 11 is towards static iron core 5.First dynamic iron core 8 is fixedly connected on the opening of oil cylinder 11, the second dynamic iron
Core 10 is movably connected in the inside of oil cylinder 11.Oil cylinder 11 and the second dynamic iron core 10 are barrel-like structure.Hydraulic oil 9 is filled in oil cylinder
11 inside.
Catch bar 4 runs through static iron core 5, and catch bar 4 can be slided with respect to static iron core 5, and catch bar 4 and the first dynamic iron core 8 are fixed
Connection.First elastic component 6 is arranged between static iron core 5 and the first dynamic iron core 8.The setting of second elastic component 7 the first dynamic iron core 8 with
Between second dynamic iron core 10.
Preferably, the first elastic component 6 and the second elastic component 7 are resetting spring.First elastic component 6 is set in catch bar 4
On.The first groove 51 is offered on static iron core 5, the first elastic component 6 is inserted into the first groove 51.
First dynamic iron core 8 includes connection main body 81 and 82 He of the first connecting pin for being connected to 81 both sides of connection main body
Second connection end 83, connection main body 81 are fixedly connected on the opening of oil cylinder 11, and the first connecting pin 82 is located at outside oil cylinder 11, simultaneously
It is connect with catch bar 4, second connection end 83 is located inside oil cylinder 11.One end of second elastic component 7 is set in second connection end 83
On.The second groove 101 is offered in second dynamic iron core 10, the other end of the second elastic component 7 is arranged in the second groove 101.
The course of work of hydraulic pressure dynamic iron core electromagnet 1 provided in this embodiment:
1. coil 3 is not powered on stream, as shown in Fig. 2, under the elastic force effect of the first elastic component 6, oil cylinder 11 is supported on
In bobbin 2.Under the elastic force effect of the second elastic component 7, the second dynamic iron core 10 is supported on the bottom of oil cylinder 11.
2. coil 3 is passed through electric current less than or equal to rated value, have one between the first dynamic iron core 8 and the second dynamic iron core 10
Fixed attraction, but attraction is not enough to overcome the elastic force of the second elastic component 7 and make the first dynamic iron core 8 and the second dynamic iron at this time
Core 10 is attracted, so, the second dynamic iron core 10 moves a certain distance rear, holding balance to the first dynamic iron core 8.
Equally, the attraction between static iron core 5 and the first dynamic iron core 8 is not enough to overcome the elastic force of the first elastic component 6, therefore
It does not move.Second dynamic iron core 10 and the second static iron core 8 under the action of magnetic adhesion, the second dynamic iron core 10 in oil cylinder 11 slowly
After moving to reach certain distance, keep balance.Certainly since the suction-combining force is too small, the first dynamic iron core 8 may also be with respect to static iron core 5 not
It is mobile.That is, catch bar 4 does not move or moves small distance relative to static iron core 5.
3. coil 3 is passed through electric current more than rated value, as shown in figure 4, having between the first dynamic iron core 8 and the second dynamic iron core 10
There are enough attractions, the first dynamic iron core 8 and the second dynamic iron core 10 is made to be attracted, enhances static iron core 5 to the first dynamic iron core 8 and the
The suction-combining force of two dynamic iron cores 10 makes the first dynamic iron core 8 and the second dynamic iron core 10 that oil cylinder 11 be driven to be quickly moving toward static iron core 5, drives
Catch bar 4 is quickly displaced outwardly.
4. after coil 3 powers off, under the elastic force effect of the first elastic component 6, oil cylinder 11 is gradually to the direction far from static iron core 5
It is mobile.Meanwhile under the effect of the elastic force of the second elastic component 7, the first dynamic iron core 8 is drifted apart from the second dynamic iron core 10, makes second
Dynamic iron core 10 shifts to the bottom of oil cylinder 11.Hydraulic oil 9 to the second dynamic iron core 10 have certain resistance, make the second dynamic iron core 10 to
The direction movement of 11 bottom of oil cylinder is slower, and the second elastic component 7 is made to improve the elastic force of the first dynamic iron core 8.But the second elastic component
The elastic force of 7 pair of first dynamic iron core 8 is less than elastic force of first elastic component 6 to the first dynamic iron core 8, so, the first dynamic iron core 8 drives oil
Cylinder 11 is slowly to moving inside bobbin 2.
The present embodiment also provides a kind of breaker, and breaker includes tripping mechanism and above-mentioned hydraulic pressure dynamic iron core electromagnet 1, liquid
Iron core electromagnet 1 is pressed for pushing tripping mechanism with disconnecting circuit.
Specifically, the coil 3 in hydraulic pressure dynamic iron core electromagnet 1 is passed through electric current more than after rated value, catch bar 4 is from static iron core
It is stretched out in 5 and hits tripping mechanism, so that tripping mechanism is detached from circuit, play the effect of disconnecting circuit.In hydraulic pressure dynamic iron core electromagnet 1
Coil 3 be passed through electric current less than electric current is not passed through after rated value or, catch bar 4 is motionless in bobbin 2.
In other implementations, it is not passed through when the coil 3 in hydraulic pressure dynamic iron core electromagnet 1 is passed through electric current less than rated value or
When electric current, catch bar 4 is not protruding, and tripping mechanism is made to keep original state, and the coil 3 in hydraulic pressure dynamic iron core electromagnet 1 is logical
Enter electric current and hit tripping mechanism more than after rated value, catch bar 4 is stretched out from static iron core 5, makes tripping mechanism disconnecting circuit.This reality
Advantageous effect with the hydraulic pressure dynamic iron core electromagnet 1 of novel offer and breaker is:
1. the movement of catch bar 4 is by static iron core 5 to the magnetic force, the first elastic component 6 and the second elastic component 7 of the first dynamic iron core 8
Elastic force and hydraulic oil 9 acted synergistically to the resistance of the second dynamic iron core 10 to realize, the movement of catch bar 4 is hardly by temperature
It influences, by the current control in coil 3, you can be accurately controlled the movement of catch bar 4.
2. in 10 attracting process of the first dynamic iron core 8 and the second dynamic iron core, hydraulic oil 9, which can play, hinders the second dynamic iron core 10
The effect of movement makes the second dynamic iron core 10 be delayed under the action of magnetic field force is attracted and reaches the first dynamic iron core 8, it is dynamic to complete long delay
The effect of work.The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
