Description
Technical field
The utility model is related to field of circuit breakers, more particularly to a kind of Ferrous Metallurgy miniature circuit breaker.
Background technology
Miniature circuit breaker, abbreviation MCB is most popular a kind of terminal protection electrical equipment in electric terminal power distribution equipment,
Short circuit, overload, overvoltage of single-phase and three-phase for below 125A etc. are protected, including monopole 1P, two pole 2P, three pole 3P, quadrupole
Four kinds of 4P etc..
Electic protection is equally vital, it is necessary to which breaker is protected by, but is due to during Ferrous Metallurgy
The operating mode of metallurgical process is poor, and when in use, turnover rate is higher for existing breaker, causes the increase of production cost, it is impossible to transport
Use in Ferrous Metallurgy production.
Utility model content
The utility model is simple in construction in view of the shortcomings of the prior art there is provided a kind of Ferrous Metallurgy miniature circuit breaker, into
This is low, is adapted to the application of iron and steel metallurgical industry.
The utility model is achieved by the following technical solution there is provided a kind of Ferrous Metallurgy miniature circuit breaker, including
Insulation shell, the operation handle being connected by torsion spring with the insulation shell, and the input contact being fixedly arranged in insulation shell
With output contact, one end that the operation handle extends inside insulation shell is conductor contact, and the conductor contact passes through wire
With it is described input contact be electrically connected with, and the torsion spring in the raw when, with it is described output contact it is in electrical contact;Institute
State conductor contact and be provided with socket on the iron block affixed with the insulation shell, the iron block with exporting the side that contact mutually deviates from
There is magnet coil, the wire two ends of the magnet coil are electrically connected with the input contact.
This programme on iron block by being socketed magnet coil so that powerful suction is produced in the case of current overload,
When suction is enough to overcome torsion spring torsion, conductor contact is separated with output contact, power-off purpose, protection machine and electricity is reached
Road, simple in construction, use time is long, and cost is relatively low.
As optimization, the input contact and output contact are extended on the outside of insulation shell, and are stretched out on the outside of insulation shell
One end be equipped with the binding post being connected through a screw thread with insulation shell.The binding post facilitates staff to carry out patching operations.
As optimization, in addition to the arc-control device being fixed in the insulation shell, the input of the arc-control device with
The input contact is electrically connected with, and output end is electrically connected with output contact.Electric arc is avoided to the wound of human body by arc-control device
Evil.
As optimization, the iron block is cylinder, and is fixed on by support inside insulation shell.Iron block is set to cylinder
Shape, Distribution of Magnetic Field evenly, and support then facilitate install.
As optimization, the insulation shell both sides external is installed with installing plate, the installing plate and offers mounting hole,
In order to be fixedly mounted.

Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, this programme is illustrated.
A kind of Ferrous Metallurgy miniature circuit breaker as shown in Figure 1, including insulation shell 1, pass through torsion spring 3 and insulation shell 1
The operation handle 4 of connection, and the input contact 14 being fixedly arranged in insulation shell 1 and output contact 5.Opened up on insulation shell 1
Hole, the big I of the hole meets swinging up and down for operation handle 4, and one end of operation handle 4 extends insulation shell 1
It is outside.
One end that operation handle 4 extends inside insulation shell 1 is conductor contact 10, and conductor contact 10 passes through wire and input
Contact 14 is electrically connected with, and torsion spring 3 in the raw when, conductor contact 10 and output contact 5 it is in electrical contact.
Conductor contact 10 and the side that mutually deviates from of output contact 5 are provided with affixed and be the iron of cylinder with insulation shell 1
Block 2, for convenience of installing, iron block 2 is fixed in insulation shell 1 by support 12, and magnet coil 13, electromagnetism are socketed with iron block 2
The two ends of wire 15 of coil 13 are electrically connected with input contact 14.
For convenience of installation and wiring, input contact 14 and output contact 5 in the present embodiment are extended outside insulation shell 1
One end on the outside of side, and stretching insulation shell 1 is equipped with outside the binding post 6 being connected through a screw thread with insulation shell 1, insulation shell
The fixed plate 7 being connected through a screw thread with binding post 6 is installed with side.
To prevent electric arc from being damaged to human body, the present embodiment also includes the arc-control device 9 being fixed in insulation shell 1,
The input 11 of arc-control device 9 is electrically connected with input contact 14, and output end 8 is electrically connected with output contact 5.
Both sides outside insulation shell 1, which are installed with installing plate, installing plate, offers mounting hole 16, facilitates this open circuit
The fixed installation of device.
In use, this breaker is series in circuit, conductor contact 10 is touched in the presence of torsion spring 3 with output when initial
Piece 5 is in electrical contact, and circuit is in "on" position;During overload, due to electromagnetic induction principle, overload current causes iron block is produced powerful
