BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switchboard, and more particularly, to an switchboard used for controlling a power source.

Generally, electricity generated by the power plant at a voltage of about 20,000V is boosted to ultra high voltage suitable for transmission and transmitted to the primary substation. In the primary substation, the supplied power is reduced to 22.9 kV and supplied to the secondary substation or each customer.

The electricity supplied from the primary substation is supplied to the reception facilities of each customer through the distribution system consisting of the processing distribution line and the underground distribution line, and is supplied to the low-pressure customer through the special-purpose customer, the high-pressure customer and various outdoor installation transformers.

The switchboard distributes the power to the devices used in urban and residential complexes. In the event of a surge or an accident occurring in the power system, the breaker is quickly opened and closed for safety after operating the breaker to isolate the fault section, To shorten the blackout time.

An internal space may be formed in the main body 110. Various units necessary for operation of the switchboard 100 may be installed in the internal space of the main body 110. A gas discharge unit 113 may be installed on the upper side of the main body 110. The gas discharge unit 113 can detect a fire in the space inside the main body 110 and discharge it to the outside.

The gas discharge unit 113 for this purpose may include a fire detection sensor 113b and an opening and closing member 113a. The fire detection sensor 113b may be installed in the internal space of the main body 110. [ The fire detection sensor 113b may be a sensor for detecting a high temperature or soot generated in a fire. The opening and closing member 113a may be installed on one side of the main body 110 and may be opened or closed depending on whether or not there is a fire. For example, the opening and closing member 113a may be installed on the upper side of the main body 110. [ When the fire detection sensor 113b senses a fire, the opening and closing member 113a receives the operation signal from the fire detection sensor 113b and opens the smoke detection sensor 113b to lower the temperature inside the main body 110 while discharging the smoke to the outside .

Meanwhile, the transmissive portion 112 may be formed on one side of the main body 110. The transmissive portion 112 is formed on at least a portion of one side of the main body 110, and may be made of a transparent material. The transmissive portion 112 may be, for example, transparent plastic. Accordingly, even if the user does not open the main body 110, the state of the internal space of the main body 110 can be visually confirmed quickly through the transmission portion 112.

Meanwhile, the photographing member 114 may be installed in the inner space of the main body 110.

The photographing member 114 can photograph the internal space of the main body 110. The photographing member 114 may be, for example, a camera. The photographing member 114 may be electrically connected to a separate monitor (not shown) from the switchboard 100. Even if the user does not open the main body 110, the user can quickly check the internal space of the main body 110 through the monitor in real time.

The power transmitting member 120 may be installed in an inner space of the main body 110 to distribute the power supplied to the main body 110 to various units installed in the inner space of the main body 110. The power transmitting member 120 may be one or more. In general, the switchboard 100 can be designed to supply electricity to other places in various ways, such as a three-phase three-wire system or a three-phase four-wire system.

Here, the three-phase four-wire type includes four wires, and the name of each wire can be generally defined as R, S, T, N or A, B, C and N, do. The user can manipulate such electric wires to connect various electric wires to each other to supply power to various devices.

Such a plurality of power transmission units may be coupled so as to cross each other when viewed in a plan view. The power transmitting member 120 may be, for example, a bus bar installed inside a general switchboard 100, and thus a detailed description thereof will be omitted.

The insulating member 130 may be disposed on one side of the power transmitting member 120. The shape of the insulating member 130 may be, for example, a columnar shape. A plurality of power transmitting members 120 may be installed in the inner space of the main body 110. Some of the plurality of power transmitting members 120 may be vertically spaced and crossed with each other.

The insulating member 130 may be interposed between the two power transmission members 120 intersected. The insulating member 130 may prevent the adjacent power supply transmitting members 120 from being electrically connected to each other and may support the power supply transmitting members 120 so that the power supply transmitting members 120 may be spaced apart from each other. The insulating member 130 may be a columnar member, and may be made of an epoxy material to facilitate insulation.

The anti-vibration member 140 may be interposed between the insulating member 130 and the power transmitting member 120. The anti-vibration member 140 can absorb vibration applied from the outside.

The anti-vibration member 140 may be a plate-like member. The material of the anti-vibration member 140 may be, for example, any one selected from rubber, sponge, and plastic. However, the material of the anti-vibration member 140 is not limited to such a material, and any material capable of absorbing vibration may be used. When an earthquake occurs, the anti-vibration member 140 absorbs vibration, so that the coupling state of the insulating member 130 and the power-transmitting member 120 can be stably maintained.

The first energization notification unit 161 may be formed on one side of the anti-vibration member 140. The first energization informing unit 161 may be turned on when the power transmitting member 120 in contact with the anti-vibration member 140 is energized.

The first energizing informing unit 161 is a light emitting diode (LED) that is coupled to the circumferential surface of the dustproof member 140 and emits light when power is supplied to the power transmitting member 120 . The light emitting device may be turned on by a power source passing through the power transmitting member 120, or may be turned on by a separate power source.

When the user confirms by opening the inside of the main body 110 of the switchboard 100 for maintenance, it is confirmed that the first energization informing unit 161 is in the lighted state and the power supply transmitting member 120 is in the energized state Without the need for equipment. Accordingly, it is possible to prevent an electric shock accident that may occur to the user in advance.

The second energization informing unit 162 may be formed on the outer surface of the main body 110. The second energization informing unit 162 may be turned on when power is supplied to the main body 110. The second energization informing unit 162 may be turned on by a power source applied to the main body 110 or by being supplied with a separate power source.

The second energization notification unit 162 may be, for example, a light emitting element sticker detachable from the main body 110. If the life of the light emitting element sticker is shortened and the light emitting element sticker is not lit even when the power is applied, the user can easily remove the light emitting element sticker from the body 110 and quickly replace it. That is, maintenance of the second energization informing unit 162 can be performed quickly.

Such a second energization informing unit 162 promptly informs the user that power is supplied to the main body 110, thereby preventing the user from being electrocuted. That is, the safety of the switchboard 100 according to an embodiment of the present invention can be further improved.

The switchboard 100 according to an embodiment of the present invention may further include a third energization notification unit 163. [ Here, the power transmitting member 120 may be a plurality of power transmitting members.

The third energization informing unit 163 may be provided on the outer surface of each of the plurality of power transmitting members 120 and may be turned on when energized. 4, when the user opens the door 115 of the main body 110 to perform maintenance, the third power supply notification unit 163 is turned on. When the power supply transmitting member 120 It is possible to quickly confirm that the power is on. As described above, the third energization notification unit 163 can promptly inform the user that the power transmitting member 120 is energized even if the user does not use any other equipment. Therefore, occurrence of an electric shock accident can be prevented in advance.

Referring to FIG. 5, the switchgear 100 according to the embodiment of the present invention may further include a fourth energization notification unit 170.

The fourth energization notification unit 170 may apply power to at least a part of the handle member 117 when power is supplied to the main body 110. The pull tab 117 may be formed on the door 115 that opens the main body 110.

When the user grasps the handle member 117 on the main body 110 in order to open the door 115 in a state where power is supplied to the main body 110, the user receives the electric stimulus and immediately hands off the handle member 117 Move.

The fourth energizing notification unit 170 may include a human body sensor 171, a conductive member 172, and a power supply unit 173.

The human body detection sensor 171 may be installed outside the body 110 to detect that the human body is close to the body 110. The human body detection sensor 171 may be a sensor that can be used to detect the proximity of the human body, and may be, for example, an ultrasonic sensor or an infrared sensor. Alternatively, the human body detection sensor 171 may include at least one photo interrupter capable of detecting a state of passage of a certain section, as another example.

The conductive member 172 may be formed of a conductive material and may be formed on a part of the outer surface of the handle member 117. It may be preferable that the conductive member 172 is not electrically connected to the knob member 117. [ This is to prevent electric power applied to the conductive member 172 from flowing to the main body 110. For this purpose, the handle member 117 may be made of a non-conductive material such as plastic. The conductive member 172 may be formed over part or all of the surface that is seen from the outside in the pull member 117.

The power supply unit 173 can supply human stimulation power to the conductive member 172 when the body detection sensor 171 senses a human body while power is supplied to the body 110. [ Here, the current value of the human stimulation power source is included in the range of 5 mA to 30 mA, for example, and the voltage value may be included in the range of 1 V to 100 V.

Such a human stimulation power supply is not limited thereto, and any value can be freely set so that the user feels stiff and harms the human body. That is, when the user holds the pull-tab 117, the conductive member 172 and the part of the human body are in contact with each other, so that an electric stimulus can be applied to the user. The user can receive the electric stimulation and can quickly release the hand from the pull-tab 117 by the reflex nerve.

Accordingly, it is possible to prevent the user from opening the main body 110 in a state where power is applied to the main body 110. That is, even if the user inadvertently grasps the handle member 117 without observing the lighting state of the second energization notification unit 162, the user can be informed of the fact that the main body 110 It can be confirmed that it is in the energized state.

As described above, the switchgear 100 according to the embodiment of the present invention includes the first energization notification unit 161, the second energization notification unit 162, and the fourth energization notification unit 170, It can be prevented more stably.

On the other hand, the fourth energization notification unit 170 may further include a locking portion 174. The lock portion 174 may be installed at a portion of the main body 110 adjacent to the door 115. When the human body detection sensor 171 senses the user while power is applied to the main body 110, the lock portion 174 maintains the locked state of the door 115 or if the locked state is released, . Accordingly, when power is applied to the main body 110, the user can not open the main body 110, thereby preventing an electric shock.

Referring to FIG. 6, the switchgear 100 according to an embodiment of the present invention may further include a dustproof pad 111.

The vibration isolating pad 111 may be interposed between the power transmitting member 120 and the main body 110. Here, the power-transmitting member 120 may be coupled to a separate frame 110a installed inside the main body 110. [ At this time, the vibration-proof pad 111 may be interposed between the frame 110a and the power-transmitting member 120.

The vibration pad 111 absorbs vibrations applied from the outside, so that the coupling between the power transmitting member 120 and the main body 110 can be more stably maintained. The material of the vibration-proof pad 111 can be any material capable of absorbing vibration, and thus is not limited to a specific material.

Referring to FIG. 7, the switchgear 100 according to an embodiment of the present invention may further include a shock absorption unit 190.

The shock absorbing unit 190 is coupled to the power transmitting member 120 so that when the vibration is applied to the body 110 from the outside, the power transmitting member 120 can be moved according to the vibration. The shock absorbing unit 190 for this purpose includes a pillar member 191, a housing member 192, a locking member 193, a driving member 194, a vibration sensing member 195 and an elastic member 196 .

The pillar member 191 may be fixedly coupled to one side of the power transmitting member 120. The columnar member 191 may be, for example, a columnar shape, but is not limited thereto and may have a polygonal columnar shape. The column member 191 may be vertically disposed at both ends of the power transmitting member 120 disposed in the left and right direction in the inner space of the main body 110, for example. That is, the pillar member 191 can be coupled to the power-transmitting member 120 at right angles.

The housing member 192 may be installed inside the main body 110. More specifically, the housing member 192 may be installed on the inner wall surface of the main body 110. [ A receiving space may be formed in the receiving member 192. The receiving space can receive the pillar member 191 and move in one direction. The accommodation space may be formed to open upwardly or downwardly from the housing member 192.

The locking member 193 can be installed on one side of the receiving member 192. The locking member 193 allows the column member 191 to be retained in the receiving member 192. [ To this end, the end of the locking member 193 may be inserted into the pillar member 191. When the locking member 193 is separated from the pillar member 191, the pillar member 191 can be relatively movable with respect to the receiving member 192. [

The driving member 194 can move the locking member 193 such that the locking member 193 is inserted into the pillar member 191 or released from the inserted state. The driving member 194 can be applied to any of the solenoids, the linear motor, the inflow cylinder, and the pneumatic cylinder so that the locking member 193 can be reciprocated.

The driving member 194 and the locking member 193 may be installed to penetrate one side of the housing member 192 in a state where they are coupled to each other. The locking member 193 can be inserted into the pillar member 191 or can be separated from the pillar member 191 by the power generated by the driving member 194. [

The vibration sensing member 195 may be electrically connected to the driving member 194. The vibration sensing member 195 may be installed inside the body 110 to sense vibration.

When the vibration sensing member 195 senses the vibration, the driving member 194 can be operated to release the state in which a part of the locking member 193 is inserted into the pillar member 191. [ More preferably, when the vibration sensing member 195 senses vibration, it can generate an electric signal that allows the driving member 194 to operate.

The elastic member 196 may be located in the receiving space of the receiving member 192. The elastic member 196 can elastically support one end of the pillar member 191. The elastic member 196 may be, for example, a compression spring.

Both ends of the compression spring can be coupled to the bottom surface of the receiving member 192 and the pillar member 191, respectively. Accordingly, it is possible to prevent the columnar member 191 from being detached from the receiving member 192 due to excessive vibration. In addition, the elastic member 196 may absorb the vibration transmitted to the shock absorbing unit 190.

When the vibration sensing member 195 senses vibration at the time of occurrence of an earthquake, the driving member 194 is operated and the locking member 193 can be separated from the pillar member 191. That is, the pillar member 191 can freely move with respect to the receiving member 192 in response to the vibration while the lock member 193 is released from the state of being inserted into the pillar member 191. [

In addition, since the vibration of the elastic member 196 can be reduced, it is possible to reduce the stress generated in the joint portion of the power-transmitting member 120, which may be relatively weak in connection with other portions. Accordingly, it is possible to further improve the earthquake resistance of the switchgear 100 according to an embodiment of the present invention.

Referring to FIG. 8, the switchgear 100 according to an embodiment of the present invention may further include an elastic deformable member 150.

The elastic deformable member 150 is made of an elastically deformable material, and a part of the elastic deformable member 150 may be bent. For example, the resiliently deformable member 150 may have a portion of a plate-like member made of metal, for example, in the shape of the letter "U".

The elastic deformable member 150 may connect the two power transmission members 120 adjacent to each other in the plurality of power transmission members 120. That is, the power transmitting member 120 may be connected to both ends of the elastic deformable member 150, respectively. The method of joining the elastic deformable member 150 and the power-transmitting member 120 may be, for example, fastened with rivets or bolts, but is not limited thereto.

As described above, the power transmitting member 120 may be plural. The plurality of power transmitting members 120 may be connected to each other in various forms to transmit power to each unshown unit included in the switchboard 100.

When the vibration is transmitted to the main body 110 due to an external earthquake, the resiliently deformable member 150 not only absorbs vibrations generated from the power transmitting member 120 connected to both ends, 120 may be slightly moved relative to each other.

Accordingly, it is possible to reduce the stress generated at the portions where the power transmitting members 120 are connected to each other by the vibration. Therefore, it is possible to further improve the earthquake resistance of the power distribution board 100 according to an embodiment of the present invention by preventing the power transmission member 120 from being damaged by vibration.

Referring to FIG. 9, the switchboard 100 according to an embodiment of the present invention may further include a power cutoff unit 180.

The power cut-off unit 180 is installed inside the main body 110 and can cut off the supply of power to the power-transmitting member 120 when a part thereof contacts the power-transmitting member 120 due to external force. The power cutoff unit 180 for this purpose may include a base member 181, an operating member 182, a moving member 183, a position restoring member 185, and a clip member 184, for example.

The base member 181 may be positioned adjacent to the power transmitting member 120. [ The base member 181 may be fixed to a frame 110a (not shown) constituting the main body 110.

The operating member 182 may be positioned adjacent to the base member 181. [ The operating member 182 can control the power supply to the power-transmitting member 120 as it is operated by an external force. That is, when the operating member 182 is pressed once, the supply of power to the power-transmitting member 120 can be cut off, and power supply to the power-transmitting member 120 can be allowed if the operating member 182 is pressed again.

The movable member 183 may be coupled to the base member 181 so as to be relatively movable in one direction. To this end, the shifting member 183 may be slidably engaged with one side of the base member 181. When the movable member 183 is positioned adjacent to the base member 181 by an external force, a part of the movable member 183 may be in contact with the power transmitting member 120 to operate the operating member 182.

The position restoring member 185 may be interposed between the base member 181 and the moving member 183. [ The position restoring member 185 may generate an elastic force so that the moving member 183 can be moved in a direction away from the base member 181.
