It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent all of the technical idea of the present invention, various equivalents that may be substituted for them at the time of the present application It should be understood that there may be water and variations.

Before describing the present invention with reference to the drawings, it is not shown or specifically described for the matters that are not necessary to reveal the gist of the present invention, that is, those skilled in the art can obviously add. Make a note.

First, the accident recovery distribution boxes 100 and 100 'are used for bidirectional lines, and in the case of FIG. 2A, the one-way wiring connection structure is used as an example. Let's find out.

The accident recovery distribution boxes 100 and 100 'include two

breakers

110a and 120b and 110b and 120a, respectively.

Here, only four circuit breakers are taken as an example, and as described above, the circuit breakers may be added or subtracted according to design conditions such as construction area and load characteristics.

The power lines of each of the two rows are connected to the breakers facing each other (110a and 110b, 120a and 120b), the breakers (110a, 120a) of one side is connected to the load to supply power and the opposite breakers (110b, 120b) are the load It is configured to be not connected to.

Here, the state that is not connected to the load includes various cases, for example, a case in which the line is first maintained in the distribution box 100 while not physically contacting the breaker.

Second, there is a case in which the breaker is already in contact with the breaker through a switching module using a power switching element.

In the circuit breakers facing each other (110a and 110b, 120a and 120b), the load is selectively disposed, in the example of Figure 2a load (111, 112, 113, 114, 115, 116) between the breakers (110a and 110b) The

circuit breaker

120a and 120b has a

load

121, 122, 123, 124, 125, and 126 disposed therein.

FIG. 2B is a diagram illustrating an example when a line break accident occurs in FIG. 2A, and FIG. 2C is a view illustrating that the line break accident of FIG. 2B is restored.

If a line break occurs between the load 124 and the load 115, power is not supplied to the

loads

121, 122, 123, 124, 115, and 116.

In this case, when the

breakers

110b and 120b that are in the standby state without being connected to the load are connected to the load, it can be seen that the accident is quickly recovered as shown in FIG. 2C.

In other words, when the track is kept in the inlet state and physically does not come into contact with the breaker at all, the worker processes the connection quickly.

In addition, if the breaker is already in contact with the breaker through the power switching module, but is still in the OFF state, the related control configuration is promptly turned on.

Therefore, it can be seen that the accident is recovered by quickly supplying power without requiring any road excavation or wiring and plumbing replacement work.

Here, the present embodiment may be applied to the case of a line disconnection accident as well as a short circuit accident.

First, the accident recovery distribution box 100 is used for a bidirectional line, but in the case of FIG. 3A, the case employed in the loop wiring connection structure is exemplified. .

In addition, the distribution box for accident recovery 100 according to the embodiment of the present invention is used in the bidirectional line, using a plurality of two-row power line, it turns out that the load can be selectively used in each of the two-row power line. .

In addition, the accident recovery distribution box 100 according to the embodiment of the present invention is found to include two breakers facing each other in the power line of each of two rows.

FIG. 3A illustrates an accident recovery distribution box 100 used in a loop wiring connection structure, and the distribution box 100 includes four

breakers

110a, 110b, 120a, and 120b.

The power lines of each of the two rows are connected using

breaker pairs

110a and 110b, 120a and 120b which are opposed to each other, but

breakers

110a and 120b on one side are connected to a load to supply and oppose the breakers 110b and 120a. ) Is configured to be disconnected from the load.

The breaker pairs 110a and 110b and 120a and 120b facing each other are selectively disposed. In the example of FIG. 3A, the

loads

111, 112, 113, 114, 115 and 116 are applied to the first breaker pairs 110a and 110b. Is disposed, and the

loads

121, 122, 123, 124, 125, and 126 are shown in the

second breaker pair

120a and 120b.

3B is a diagram illustrating an example when a line break accident occurs in FIG. 3A, and FIG. 3C is a diagram illustrating that the line break accident of FIG. 3B is restored.

If a line break occurs between the load 121 and the load 112, power is not supplied to all the loads except the

loads

111 and 121.

In this case, when the

breakers

110b and 120a, which are not connected to the load and are connected to the load, are connected to the load, it can be seen that the accident is quickly recovered as shown in FIG. 3C.

In FIG. 3A, an example in which the breaker 120b is constructed to provide power in opposing

breaker pairs

120a and 120b is illustrated. In FIG. 4A, an example in which the breaker 120a is constructed to provide power first is shown.

Depending on the design conditions, a circuit breaker that provides power first among opposing

breaker pairs

110a and 110b and 120a and 120b may be selectively installed, and may vary depending on the construction area and load characteristics.

4B is a diagram illustrating an example when a line break accident occurs in FIG. 4A, and FIG. 4C is a diagram illustrating that the line break accident of FIG. 4B is restored.

If a line break occurs between the load 121 and the load 112, it can be seen that power is alternately supplied to the loads arranged.

That is, the structure of FIG. 4A is that the load can be actively employed in an area such as a security light or a light, and has an advantage in that an additional disconnection zone is prevented even if a line break accident occurs, thereby preventing additional accidents until just before recovery. I will.

When an accident occurs as shown in FIG. 4B, when the

breakers

110b and 120b which are not connected to the load but are in a standby state are connected to the load, the accident can be quickly recovered as shown in FIG. 4C.

FIG. 5A is a diagram illustrating an accident recovery distribution box according to a fourth exemplary embodiment of the present invention in a loop wiring connection structure, and FIG. 5B is a diagram illustrating an example when a line break accident occurs in FIG. 5A. to be.

The distribution box 100 includes breaker pairs 110a and 120a, and it can be seen that a closed loop is formed at two (+) and (-) terminals of each breaker.

As shown in FIG. 5B, even when a disconnection accident occurs between the load 121 and the load 112, the power can be supplied to the entire load without the load being turned off, and it can be seen that the accident can be automatically recovered. Can be.

If a one-line ground fault occurs as shown in FIG. 6A, the failure point can be measured as shown in FIG. 6B.

That is, if the guideline of the galvanometer (G) is zero, R1 / R2 = R3 / R4 is established by the equilibrium principle of the bridge circuit, and the cable conductivity ρ, cable cross-sectional area A, cable length L, and the point of failure If the length is l, then R3 = ρ (2L-1) / A and R4 = ρl / A.

Therefore, R1 / R2 = (2L-1) / l, and the distance l from the measuring point to the failure point is 2R2L / (R1 + R2).

However, if a two-wire ground fault occurs, the auxiliary line must be newly installed to use the Murray loop method as described above, because a loop structure must be made.

The accident recovery distribution box 100 according to the fifth embodiment of the present invention includes a Murray loop measurement module.

The Murray loop measurement module may be utilized when a distribution box is used in a loop wiring connection structure, and when a 2-wire ground fault occurs, the failure point may be measured using the measurement module.

In other words, if applied to the loop wiring connection structure, the length to the point of failure can be measured without the need for a new auxiliary line, and the accident point can be found quickly by using it.

In addition, the distribution box 100 for accident recovery according to the fifth embodiment of the present invention includes a plurality of breakers, each breaker is configured to further include a switching module and a USN (Ubiquitous Sensor Network) communication module.

In addition, the control system of the distribution box for accident recovery includes the distribution box 100 and the control terminal 200.

The switching module is a component that performs a function of turning on / off a power supply to a load by using a power switching element, and is configured to operate under the control of the control terminal 200.

The USN communication module functions to operate each breaker as an identifiable sensor node and is designed to operate in an operating system designed for the sensor network.

That is, each breaker has an identifiable node ID and is configured to perform wireless communication with the control terminal 200.

For example, an operating system such as TinyOS, MANTIS, PEEROS, or T-Engine may be applied, and the wireless network may adopt a Zigbee communication technology, which is a short range wireless communication technology.

For example, if TinyOS is adopted as the operating system of the sensor network, the message transmitted by the USN communication module may follow the TOS_Msg rule. In this case, the node ID is inserted into the payload and transmitted.

Depending on the design conditions, it can of course be configured to follow other operating system and message rules for the purposes of the present invention.

The control terminal 200 is configured to include an operation interface, a control module and a USN communication module.

The operation interface is designed to include an interface such as a display window and various operation buttons formed on the surface of the control terminal 200, and is configured to interwork with a control module and a USN communication module inside the control terminal 200.

The control module performs a function of processing an ON / OFF control command of the switching module included in each breaker processed through a button of the control terminal 200.

The USN communication module performs a function of processing a control command by communicating with the USN communication module of each breaker identified by the sensor node ID in association with the control module.

Therefore, according to the distribution box control system according to an embodiment of the present invention, when a short circuit or a line disconnection accident occurs, the operator carries the control terminal 200 and come to the site to turn on / off (ON / OFF) of each breaker only by button operation By processing the control, it can be seen that the accident can be recovered quickly.

Preferably, the system according to the embodiment of the present invention can be designed to operate in conjunction with other power control system, of course.

Depending on the design conditions, some modules included in the control terminal 200 may be configured in advance to be configured to be included separately in the distribution box 100.

1 to 7 described above, only the main matters of the present invention have been described, and as long as various designs can be made within the technical scope of the present invention, the present invention may be applied to the configurations and functions of FIGS. 1 to 7. It is obvious that it is not limited.
