Description

[0001] Switchboards for stable power arrangement of apartment houses [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric power distribution board for stable power supply arrangement of a residential house, and more particularly, One side is bent and deformed due to the external impact caused by the wire being pulled in and out through the cable guide that is connected. It is possible to guide the wire more safely while preventing damage due to the restoration function. The present invention relates to a switchboard for stable power supply arrangement of a multi-family house that completely prevents the risk of a safety accident that may occur while children play hide-and-seek while playing.

In general, apartment houses are equipped with a power distributor that distributes and supplies the power supplied to various loads, and detects the state of the voltage supplied to the load to promptly shut off the electricity in the event of an abnormal state such as a short circuit. And a power meter for measuring the total amount of electric power used for a certain period of time, and the like are installed in the switchboard.

The switchboard is usually installed on the wall when the building is installed, and some of the switchboards are installed so as to be exposed to the outside, so that the selective supply of electricity can be controlled as needed, and the management and maintenance are made convenient.

Usually, four to six wires are branched from one high-voltage power source in the switchboard, and a plurality of power distribution boards are usually arranged at regular intervals inside the switchboard.

Meanwhile, a plurality of electric wires drawn into and out of the concrete wall of the building, particularly, a plurality of electric wires to be distributed are divided into a certain position inside the switchboard and then drawn out into the concrete wall. In this case, the gap between the switchboard and the concrete wall is finished, A connector is used to guide the user.

Such a connector is hollow pipe type, one end is buried in the concrete wall, and the other end is guided to the branching wire in the switchboard. Therefore, it is inevitably vulnerable to external earthquake and deformation of the building due to aging. There is a danger that the wire may be distorted and the sheath of the wire may be peeled off or worn to be exposed to various safety accidents such as short-circuit.

Therefore, the patent registration No. 1219138 (December 31, 2012) has already been proposed in order to detect the presence or absence of the connection state with the concrete wall and to cope with a safety accident.

In the above-mentioned prior art patents, it is possible to check from outside whether a connection member is deformed or broken by electronic sensing and control from a hollow connecting member installed to be embedded in a concrete wall, so that repair and replacement can be performed in a timely manner Respectively.

However, the prior art patent is extremely complicated in the construction of the connecting body, and it is a very uneconomical disadvantage in terms of maintenance since it is required to electronically detect when the connecting body is deformed or broken by the external pressure to repair or replace have.

Especially, the damage of the connector due to the deformation of the building is not often occurred. However, the monitoring and management system of the connector for this is not only inefficient, but also has the problem that the operability of the sensor is inaccurate.

However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 1, the switchboard for stable power supply arrangement of the apartment house according to the present invention includes a base panel 11 of an insulating material fixedly installed in the cabinet 10, And a switch 13 provided at a middle portion of the branch circuit 12 for connecting or disconnecting the branch circuit 12.

At this time, the base panel 11 of the branching circuit 12 forms an output terminal 15 together with the input terminal 14, and the input line 16 and the input line 16 are connected to the input terminal 14 and the output terminal 15, respectively. Lead wires 17 are respectively connected.

Accordingly, the electricity supplied through the lead line 16 is branched and output through the lead line 17. The lead line 16 is provided as a high-voltage single line, while the lead line 17 is formed as low-voltage cables.

The power distribution box 10 is generally provided so as to be partially embedded in the concrete wall of the building and a cable guide 20 is provided at a boundary portion between the power distribution box 10 and the concrete wall so as to guide and guide the electric wires branched for power distribution. do.

2 to 4, the cable guide 20 includes an outer guide 21, an inner guide 22, a tension spring 23, an outer cover 24, and an inner cover 25 ) Are combined with each other.

Particularly, the outer guide 21 and the inner guide 22 each have a tubular configuration that allows the center to pass through in the longitudinal direction so as to allow the wire to pass therethrough, And the inner guide 22 is provided so as to protrude into the interior of the cabin 10.

The cross section of the outer guide 21 and the inner guide 22, which are in contact with each other, is curved in one guide direction so that the other guide is recessed in the same manner as the curved surface,

That is, the mutual contact surfaces are formed to have a constant curvature.

The opposite ends of the outer guide 21 and the inner guide 22 are horizontally bent outward to form flange surfaces 210 and 220 having a predetermined diameter. The flange surfaces 210 and 220 are formed with the same The inner end portions of the euthanasia holes 211 and 221 are formed to have a larger diameter while the fitting holes 211 and 221 are formed so as to penetrate the plate surface with a constant width by a predetermined length to the outer side of the guides 21 and 22 on the vertical line, So that a plurality of images are formed at equal intervals along the paper surfaces 210 and 220.

In addition, it is preferable that threads 212 and 222 are formed on the outer peripheral surface of the flange surfaces 210 and 220, respectively.

The tension spring 23 of the cable guide 20 has a structure in which both end portions of the coil spring are extended by a predetermined length so that the locking ring 230 is formed at the extending end, 21 and the inner guide 22 through the fitting holes 211 and 221 between the flanges 210 and 220 facing each other so that the respective hooks 230 can be inserted into the corresponding flanges 210 and 220 So that the outer guide 21 and the inner guide 22 are pressed against each other at a constant elastic force.

That is, the length of the tension spring 23 is shorter than the distance between the flange surfaces 210 and 220 of the outer guide 21 and the inner guide 22, so that the tension springs 23 The contact strength between the contact surfaces of the outer guide 21 and the inner guide 22 becomes stronger due to the pulling force of the tension spring 23 when the respective hooks 230 of the inner guide 22 are hooked.

The outer cover 24 and the inner cover 25 are screwed to the respective flange surfaces 210 and 220 of the outer guide 21 and the inner guide 22 and the outer cover 24 and the inner cover 25 Are brought into surface-contact with mutually corresponding surfaces of the flange surfaces 210 and 220, respectively.

When the outer cover 24 and the inner cover 25 are screwed together so as to cover the outer circumferential surfaces of the flange surfaces 210 and 220 so that the end portions of the fitting holes 211 and 221 formed on the flange surfaces 210 and 220 are closed, The tension springs 23 connected to the flange surfaces 210 and 220 are prevented from being separated from each other and the tension springs 23 are isolated from the outside while being protected from external impact or impact.

It is most preferable that the outer cover 24 and the inner cover 25 are spaced apart from each other by a predetermined distance.

As described above, the operation of the switchboard for stable power supply arrangement of the apartment house according to the embodiment of the present invention will be described in more detail as follows.

FIG. 5 is a coupled state view showing a structure in which electric wires are routed through a cable guide of a distribution board for stable power distribution of a apartment house according to the present invention.

As shown in the figure, the switchboard for stable power supply arrangement of the apartment house according to the present invention is embedded in the concrete wall body 100 while the lead wire 16 is drawn from the outside into the inside of the distribution box 10 from the outside, And the outgoing line 17 drawn out from the output terminal 15 is led out to the outside of the distribution box 10 on the other side.

In this way, the cable guide 20 is provided at the boundary portion drawn into the interior of the cabinet 10 and at the boundary portion drawn out to the outside of the cabinet 10 so that the cables can pass through stably.

At this time, the cable guide 20 is fixed firmly while the outer cover 24 is embedded in the concrete wall 100, and the inner cover 24 is installed to protrude into the cabin 10.

When the electric wire is drawn or drawn through a hole penetrating the center of the cable guide 20, the electric wire can be safely drawn out between the concrete wall 100 and the distribution box 10.

On the other hand, if an external force is applied to the concrete wall 100 of a building such as an earthquake or an inside of a building, an impact will naturally be transmitted to the cable guide 20.

In this case, even if the cable guide 20 is directly impacted, the cable guide 20 of the present invention has a plurality of tension springs 23 disposed inside the concrete wall 100 and on the side of the cabin 10, So that when an external force is applied to one side, it is bent at a certain angle as shown in FIG. 6 and is restored to its original shape by the tension spring 23 again.

If the outer guide 21 of the cable guide 20 and the inner guide 22 are sufficiently separated from each other, the concrete wall 100 to which the power distributing box 10 of the present invention is fixed may be severely damaged. So that the cable guide 20 is hardly deformed or damaged in the case of an impact of a considerable degree, and therefore, the cables guided by the cable guide 20 can be more safely guided and guided .

In addition, in the present invention, as in the example of FIGS. 7 and 8, the double-time gun unit 300 is further provided on the upper frame FRM on which the power distribution door DR of the distribution cabinet 10 is installed.

The dual seal gun unit 300 can not only rotate the upper end of the power distributing door DR but also rotate the double door lock unit DR in addition to the basic locking function of the key holder HOL and the key KEY installed on the power distributing door DR, Lt; / RTI >

This can lead to safety accidents such as the children entering the open cabinets 10 while they are playing hide-and-seek, etc., because the worker often leaves the cabinet 10 without accidentally locking the key (KEY) Therefore, even if the key KEY is not locked, the dual-purpose gun unit 300 is always locked so that such a safety accident can be blocked from the beginning.

An ID card reader 400 is installed in the door frame DRF on which the power distribution door DR is installed and a unit controller 310 is embedded on the upper side of the door frame DRF.

At this time, the unit controller 310 has a built-in memory, and is configured to register an ID card for registration of an admission-authorized person, which is a known technology, and thus a description thereof will be omitted.

The ID card reader 400 is electrically connected to the unit controller 310 to immediately compare the ID information read by the ID card reader 400 with the unit controller 310 and determine whether the ID information is the permitter .

Since the power distribution door DR can be closed and locked while the worker enters the inside of the distribution cabinet 10, the ID card reader 10 is also installed inside the cabinet 10 so that the power distribution door DR can be opened inside the cabinet 10. [ (400) is particularly preferable.

In addition, when the power distribution door DR is to be opened quickly due to an emergency such as a fire, the emergency switch 500 is operated so that the power supplied to the double signal unit 300 can be disconnected and manually opened and closed For this purpose, the emergency switch 500 is installed on the upper frame FRM, which is the upper end of the front surface of the cabinet 10, which is not reachable by a child.

Meanwhile, the double hand gun unit 300 includes a key board 320, as shown in FIG.

At this time, the locking plate 320 is opened and closed according to a control signal of the unit controller 310 as a blocking plate for preventing door opening.

One end of the timing plate 320 is integrally fixed to an outer circumferential surface of the bushing 330. A rotary shaft 340 is inserted into the bushing 330 and the rotary shaft 340 is inserted into the bushing 330, And is rotatably fixed to the rotation guide ring 352 of the fixed block 350 fixed to both sides of the front side of the upper frame FRM.

A driven gear 360 is fixed to one end of the rotary shaft 340 and a driving gear 370 is coupled to the driven gear 360. The driving gear 370 is driven by a driving motor 380 Respectively.

In addition, it is preferable that the double-handed gun unit 300 is covered so that the external appearance is not exposed through a separate cover.

5% by weight of 1-chloro-2,3-epoxypropane, 5% by weight of methyltrimethoxysilane, 10% by weight of polyvinyl alcohol, and silicone resin 10% by weight, triethanolamine 2.5% by weight, petrolatum 1.5% by weight, and the rest of the polycarbonate resin.

Here, 1-chloro-2,3-epoxypropane is added as a chlorine-based material having a high reactivity for stabilizing the reaction of the composition, and methyltrimethoxysilane is improved in durability by strengthening the bonding force between emulsified materials by hydrophobicity .

In addition, polyvinyl alcohol is added to enhance the acid resistance and chemical resistance, so as to increase the bonding force between components. The silicone resin is a polymer mainly composed of silicon and oxygen bonds, and enhances the bonding force to strengthen the binding force between the constituents. And triethanolamine is a weakly alkaline buffer added to control acidity. Petrolatum is an ointment-like material composed mainly of amorphous solid hydrocarbons and is waterproof and added to enhance the formation, and polycarbonate The resin is a base resin.

9, when the power distributing door DR is closed, the unit controller 310 recognizes the closing of the power distributing door DR so that the power distributing door DR is seated in the door frame DRF so that the unit controller 310 can close and fix the locking plate 320. [ A limit switch (LMT) can be further provided on the surface.

The limit switch LMT is electrically connected to the unit controller 310 and transmits a detection signal. The unit controller 310 that receives the detection signal drives the driving motor 380 to close the condition board 320 So that the power distribution door DR is automatically locked so as not to be opened.

At this time, when the limit switch LMT, to which the drive motor 380 is locked, transmits a detection signal, the unit controller 310 operates the solenoid-type locker LOC to rotate the drive gear 370, When the open signal is received, the solenoid-type locker (LOC) is operated in the opposite direction to release the lock state so that the drive gear 370 is in a rotatable state.

To this end, a solenoid-type locker (LOC) is further installed in the upper frame FRM, and is electrically connected to the unit controller 310 to be controlled.

Particularly, an insertion groove (GOV) is formed on one side of the driving gear 370 so that the solenoid type locker (LOC) can be inserted and removed. At least one stopper (STP) is formed around the inner diameter of the insertion groove (GOV) So that the solenoid-type locker (LOC) can be caught and fixed when the solenoid-type locker (LOC) is inserted.

As described above, in the double seal key unit 300 according to the present invention, the authorized worker first opens the keyhole (HOL) with the key KEY to release the primary lock, and then transmits the ID card held by the authorized user to the ID card reader 400 Lt; / RTI >

Then, the unit controller 310 recognizes this and rotates the driving motor 380 in the counterclockwise direction by rotating the locking plate 320 in the counterclockwise direction to create an unlocking state in which the power distribution door DR can be opened.

Accordingly, the operator opens the power distribution door DR and enters the inside to perform the necessary work.

When the power distribution door DR is closed after the completion of the operation, the unit controller 310 closes the cushion plate 320 in the opposite direction of the above-described opening operation according to the detection signal of the limit switch LMT, Since the safety lock is performed even if the key is not locked with the key, the child can not open the power distribution door (DR), thereby preventing a safety accident.
