Description

Switch automatic opening and shutting device {APPARATUS OPERATING ON / OFF SWITCH}

The present invention relates to a switch automatic switchgear, and more particularly to a switch automatic switchgear that can automatically and quickly perform the arc generated in the process of supplying / blocking the power of the wall switch.

In general, electric arcs generated from various devices for selectively supplying or shutting off power can raise temperatures above the ignition point of most combustible materials, which can cause serious fires.

For example, old wires in your home can cause arcing that can cause fire. Here, arcs are inherently unstable and usually do not last long enough to cause a fire.

However, under certain conditions that reflect the characteristics of electrical disturbances, the sustainability of the arc and the likelihood of a fire are much higher.

In particular, two types of arcs can be generated at home: That is, a contact arc is generated in addition to the arc caused by the defect of the wire as described above.

The contact arc arises from a high resistance in series with the load. This can be caused by loose contact, oxidation (corrosion), or removal of non-conductive foreign material in the conductive path.

In other words, poor operating environment and moisture, small metal manipulation, contamination, etc., form an electrically conductive path in the insulator between the faulty charged conductor and the system having a different potential.

The conductive path thus formed has a high resistance without immediately generating a complete short circuit between different potentials in the system.

Therefore, the fault current until forming a complete short circuit is often limited and is not detected by the wiring breaker to be connected to the upper part from the location of the fault. These failures cause catastrophic physical and human damage, as they do not flow enough current to be detected and maintain an arc that can create a fire hazard.

A system capable of preventing such damage is necessarily required, and in particular, an arc breaker for blocking the arc is essential. At this time, in order to test the malfunction of the arc breaker, an arc breaker is installed in the actual site, and the malfunction is determined by evaluating the arc detection performance and the arc breaking operation performance with respect to the arc generated in various ways for each load.

However, since various arcs generated in the actual field are the average current flowing through the contact arc only current due to the load itself, in order to confirm the arc detection malfunction, each corresponding arc breaker is installed in the actual field and manually operated. Since it is necessary to monitor the operating situation one by one, it is very troublesome, and has the problem of time and human loss.

Therefore, the present invention was created to solve the problems as described above, an object of the present invention is to automatically open and close the switch to automatically detect the arc generated when the operation of the ON / OFF switch mounted on the wall It is to provide a device.

As shown, the automatic switch opening and closing device according to an embodiment of the present invention includes a rotary shaft 10, the operating rod 20 and the operation unit 30.

The rotary shaft 10 is to be formed below the support plate (P) provided separately. Here, the support plate P is disposed to be spaced apart from the ground by a member such as a vertical plate (not shown) or a support leg (not shown) so as to be supported with respect to the ground.

That is, the rotation shaft 10 is supported by the support plate (P) and is arranged to be rotatable in one direction, such a rotation shaft 10 to be rotated by a drive means (not shown), such as a separate motor. Can be.

In addition, the rotary disk 11 is formed on the same shaft to be integrally rotated with the rotary shaft 10. At this time, the rotary disk 11 may be formed in a disk shape having a diameter larger than the rotary shaft (10).

Here, the slot 12 which is cut outward in the radial direction from the center of the rotary disk 11 is formed. The slot 12 is formed in the form of a long hole having a predetermined distance. These slots 12 are connected to one end of the operation rod 20 to be described later to allow the eccentric rotation.

Therefore, the operation rod 20 serves to convert the rotational movement of the rotary shaft 10 into a linear movement. That is, one end of the operation rod 20 is coupled through a coupling member such as a bolt (not shown), a washer (not shown) so as to be rotatable with respect to the slot 12 of the rotary disk 11, such a coupling member It will rotate about (21, 22).
