Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and can being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed
Describe in detail bright as after.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
See Fig. 1, a kind of intelligent breaker described in this utility model one preferred embodiment, including housing 10, be arranged on
Operating mechanism in housing 10, conductor structure, arc-control device, trip gear, wherein
-trip gear includes the magnet exciting coil 52 that circuit module 51 electrically connects, horizontally disposed spring with circuit module 51
53 and the fork 54 that is rotationally connected with housing 10, one end of magnet exciting coil 52 is electrically connected with circuit module 51, the other end with
One end of spring 53 connects, and is connected with the end of fork 54 by the other end of spring 53；
-conductor structure include two can in fork 54 swing process respectively with the contact chip 31 of 54 liang of end in contact of fork,
Two contact chips 31 are connected to the conductor 32 electrically connected with external circuit, and wherein a conductor 32 is provided with moving contact 33 and stationary contact
34；
-operating mechanism includes the current limiter 21 that one end is connected, the other end is connected with circuit module 51 with external circuit；
-arc-control device is the two insulation oil tanks 41 being arranged near moving contact 33 and static contact 34, fills out in insulation oil tank 41
It is filled with insulating oil.
This utility model judges the electric current in external circuit, when in external circuit by operating mechanism i.e. current limiter 21
Electric current exceedes the electric current that current limiter 21 allows to pass through, then stop the circuit of external circuit to flow into so that circuit module 51 is supplied to
The electric current of magnet exciting coil 52 diminishes, and the magnetic force of magnet exciting coil 52 weakens, and no longer holds spring 53, and spring 53 resets, pushing outward
Bar 54, fork 54 swings so that fork 54 does not contacts with two contact chips 31, so that circuit breaker internal loop disconnects, no longer
Transmission electric current.When the moment that circuit breaker internal loop disconnects, the when that moving contact 33 and static contact 34 being disconnected from each other, produce electric arc,
High arc temperature makes the insulating oil evaporation gasification in the insulation oil tank 41 that it is neighbouring and thermally decomposes, and forms arc extinguishing very capable
Gas (mainly hydrogen) and the higher bubble of pressure, make electric arc quickly extinguish.Certainly, when the electric current in external circuit is in current limliting
In the range of device 21 can carry, circuit module 51 is supplied to the normal electric current of magnet exciting coil 52, makes magnet exciting coil 52 possess relatively
Strong magnetic force, it is possible to steadily held by spring 53, when spring 53 is held, inwardly draws fork 54, makes the two ends of fork 54 divide
Do not contact with two contact chips 31, so that it is guaranteed that the home loop connection of chopper, it is allowed to the electric current of external circuit passes through chopper.
For guaranteeing that the two ends of fork 54 can contact with two contact chips 31 respectively efficiently, this utility model is at fork 54
The end of two ends and two contact chips 31 is equipped with inclined-plane 60, and the inclined-plane 60 making fork 54 two ends can be in fork 54 swing process
Fit in inclined-plane 60 with two contact chip 31 ends respectively.Utilize inclined-plane 60 to contact, considerably increase contact area, thus avoid
The situation of loose contact occurs.
Concrete, for making fork 54 can swing under the effect of spring 53, this utility model runs through in housing 10 to be had
Rotating shaft 11, through the middle part of fork 54 and can make fork 54 rotate to it rotating shaft 11.
For improving the safety of chopper further, the operating mechanism in this utility model also includes arranging through housing 10
Hand switch 22 on circuit module 51.When current limiter 21 breaks down, make circuit module by stirring hand switch 22
51 are switched on or switched off magnet exciting coil, thus are switched on or switched off external circuit.
Operation principle of the present utility model is as follows:
During use, one end of current limiter 21 is connected with the live wire of external circuit, is provided with moving contact 33 and static contact 34
The two ends of conductor are all connected with zero line, and another conductor is connected with live wire, to be connected with the home loop of chopper external circuit.
When breaking down in external circuit, such as short circuit or overload, electric current exceedes the current limit of current limiter, then stops the circuit of external circuit
Flow into so that circuit module is supplied to the electric current of magnet exciting coil and diminishes, and the magnetic force of magnet exciting coil weakens, and no longer holds spring, bullet
Spring resets, pushing bar outward, and fork swings so that fork does not contacts with two contact chips, so that break in circuit breaker internal loop
Open, no longer transmit electric current.When the moment that circuit breaker internal loop disconnects, the when that moving contact and static contact being disconnected from each other, produce electricity
Arc, high arc temperature makes the insulating oil evaporation gasification in the insulation oil tank that it is neighbouring and thermally decomposes, forming arc extinguishing very capable
Gas (mainly hydrogen) and the higher bubble of pressure, make electric arc quickly extinguish.
The above is only preferred implementation of the present utility model, is not limited to this utility model, it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, it is also possible to do
Going out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
