Bus duct two sides, and screw is tightened, play on-off protective effect.Therefore, the safety of jack box and sensitivity are most important
's.
The safety of jack box, which is divided into, uses safe and operational safety.In use, due to jack box internal current
And the characteristics of use environment, shell are easy to produce electrification phenomenon；Operational safety then focuses mainly on internal structure operation, most important
The operation for being powered off switch, the stability of cut-off switch is to be directly related to its using effect.
Existing jack switch case is mainly automatically powered off using the realization of common air switch, but this power-off effect
There are certain failure rates, and are affected by a natural, and utility model CN201956637U is arranged for busway inserting case
The electromagnetic lock of electrification accidentally pulling device, using the electric current of air switch as switching, electromagnetic lock remains turned-off in the case of electrification is mentioned
The safety of high jack box.The electromagnetic structure element extremely low as highly-safe, failure rate, there has been no automatically power off in jack box
The application of aspect.
Electromagnetic switch structure is usually applied to the elements such as socket, insert row, relay, but using less in jack box.This
There is gap in the field and jack box field of a little elements, and jack box belongs to emerging element, and structure is larger, is in bus duct and ammeter
The important critical point of case, different from directly using for said elements, present invention conversion spans the obstacle that uses of different field, significantly
Improve the safety and stability in jack box field.
Therefore, the present invention provides one kind and efficiently automatically powers off jack box.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of auto-cut-off type jack boxes.
The present invention is achieved by the following technical programs.
The purpose of the present invention is to provide the present invention to provide a kind of efficient auto-cut-off type jack box, and the jack box includes

Cooling fin on the side plate is set, and the cooling fin extends outwardly perpendicular to the side plate, and the jack box further includes preventing
The intelligent switch unit of plug operation is only carried out when its short circuit, the switch unit connects conducting wire, and switch unit includes certainly
Lock-switch, the button for controlling self-lock switch and the breaking units for the button press in short circuit, button are set to chamber door
On, breaking units include permanent magnet, electromagnet, guide rod and the first spring, electromagnet be fixed on shell 1 and with conducting wire string
It connects, guide groove is provided on electromagnet, guide rod sliding is arranged on guide groove, and permanent magnet is fixed on one end of guide rod and connects with button
It connects, the first spring is set on guide rod, and one end of the first spring is connect with electromagnet, and the other end is connect with permanent magnet, is pulled forever
Magnet and electromagnet make electromagnet and permanent magnet when the electric current in conducting wire is lower than preset value, and conductor wire is worked as in holding position
When the electric current of road is more than preset value, electromagnet pushes permanent magnet to stir button, disconnects self-lock switch.
Bus duct connects grafting tank inlet, and connection power meter in jack box outlet powers on, when short circuit occurs for circuit,
Electric current in circuit increases, and improves the magnetic field force of electromagnet, and electromagnet pushes permanent magnet mobile towards conducting wire, drives button court
Conducting wire is mobile, disconnection self-lock switch, disconnecting circuit, does not have electric current to flow through in circuit, and the magnetic field force of electromagnet disappears, and first
Spring drives permanent magnet return.
The beneficial effects of the present invention are:
The present invention realizes the function of short circuit power-off by the structure of button, electromagnet, permanent magnet and self-lock switch, and structure is more
Add simple, compact, diminution overall volume, efficient and sensible.Needing to disconnect or when connection circuit, user can also by press by
Button 5 drives self-lock switch opening and closing, so that it is switched on or switched off circuit, it is easy to operate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of jack box；
Fig. 2 is the structural schematic diagram of intelligent switch unit.
Specific embodiment
Technical solution of the present invention is described further below, but claimed range is not limited to.
As shown in Figure 1 and Figure 2, jack box shown in the present invention includes cabinet, and cabinet includes chamber door 1, bottom 2 and chamber door
And the both side plate 11 that is respectively connected with of bottom and two sealing plates 12 and the cooling fin 13 being arranged on the side plate, cooling fin is vertical
Extend outwardly in the side plate, which is characterized in that the jack box further includes the intelligence for preventing from carrying out plug operation when its short circuit
Switch unit 4, the switch unit connect conducting wire, switch unit include self-lock switch, for control self-lock switch by
Button 5 and breaking units for the button press 5 in short circuit, button 5 are set on chamber door, and breaking units include permanent magnet 6, electricity
