Description

Distribution board with disaster prevention function

[0001] The present invention relates to a distribution board with a disaster prevention function, and more specifically, to a distribution board with a disaster prevention function that provides a vibration-proof function against external shocks applied in various directions due to ground movement when an earthquake occurs, thereby preventing damage and malfunction due to the shock, and furthermore, to enable rapid follow-up measures to protect the distribution board from earthquake phenomena by detecting and monitoring in real time whether an earthquake has occurred, the occurrence cycle, the magnitude of the shock, etc., and further, to enable the detected information to be utilized as information data for establishing measures to prevent damage to the distribution board due to an earthquake, and to prevent damage to high-voltage power equipment and large-scale disasters in distribution equipment that may occur due to a fire accident caused by an unforeseen cause.

[0002] In general, most of the electricity produced domestically is transported to each region along high-voltage power lines in a complex way along the power grid, and in order to minimize the losses that occur during this process, high-voltage power is being promoted to supply it to each household.

[0003] High-voltage power supplied in this manner is divided into several power demand areas through distribution panels (hereinafter referred to as distribution panels), and therefore, these distribution panels are recognized as important devices that electrically connect power supply means and electrical / electronic components and create power branch points.

[0004] Industrial facilities such as factories use three-phase AC power, so high power is required. The AC voltage of tens of thousands of volts supplied from the power plant through the transmission line is reduced to an AC voltage of several thousand volts through a transformer, and the distribution board supplies this reduced AC voltage to each facility in the factory. In each distribution board, in order to supply high voltage and high current to the facilities within each factory, each facility and the distribution board are usually connected with a busbar. In the distribution board that performs this distribution, when connecting several electric panels, the electrical connection between adjacent electric panels is connected using the busbar.

[0005] Meanwhile, since the components inside the distribution board handle large currents, heat generation is inevitable. In particular, as the busbars exposed to heat contract and relax, the fixing bolts that hold the busbars in place naturally loosen. In this area, electrical contact resistance increases, increasing the possibility of ignition due to heat or sparks. Therefore, distribution boards are essential to be equipped with fire prevention equipment.

[0006] In addition, although switchboards are equipped with seismic structures to protect internal equipment from natural disasters such as earthquakes, most are equipped with equipment that can only respond to either fire or earthquakes, making it difficult to proactively respond when a fire occurs due to poor connection between internal components caused by an earthquake.

[0007] In addition, the vibration control structure of the distribution board is mainly implemented by installing a damper on the lower leg that supports the distribution board to cushion vibrations and minimize damage to the distribution board. However, this structure had a problem in that it could not accurately detect earthquakes when an actual earthquake occurred or when the ground tilted due to vibration.

[0033] To fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same parts are sometimes depicted with the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the gist of the present invention are omitted.

[0034] A distribution panel (hereinafter referred to as a distribution panel) having a fire prevention function according to the present invention can be broadly defined as including a main body (10), a damper (100), and a fire extinguishing unit (200).

[0035] First, the main body (10) is formed in the form of a box that forms the exterior of the distribution panel, and basic distribution devices such as circuit breakers, lightning arresters, fuses, and switches can be installed inside, and the main body (10) can protect these distribution devices by wrapping them from the outside.

[0036] Since the main body (10) can adopt the structure of a distribution box in a normal distribution panel, a detailed description thereof is omitted below.

[0037] Next, the damper (100) is installed at the lower part of the main body (10) and serves to support the main body (10) away from the installation surface, and in particular, in addition to the function of preventing external shock due to ground movement when an earthquake occurs, it detects in real time whether an earthquake has occurred, the occurrence cycle, the magnitude of the shock, etc., so that a quick follow-up response can be made, and also the detected information can be used as information data for establishing measures to prevent damage to the distribution board due to an earthquake.

[0038] A damper (100) for this purpose can be broadly exemplified as including a housing (110), a lower bushing (120), an upper bushing (130), a connecting anchor (140), a contact pin (150), a buffer portion (160), and a vibration detection portion (170).

[0039] The housing (110) constitutes the overall appearance of the damper (100) and has a tubular shape with an open upper portion, a lower portion supported on an installation surface, and an upper portion arranged at a certain distance from the lower surface of the main body (10).

[0040] Although not shown, a flange that is in contact with the installation surface can be extended and installed at the bottom of the housing (110), and anchors can be cross-connected to this flange in the direction of the installation surface to stably position and fix the damper (100) on the installation surface.

[0041] Meanwhile, the installation surface referred to in this description may refer to the ground on which the distribution panel is installed or may refer to the base panel.

[0042] Again, in a predetermined space provided inside the housing (110), a lower bushing (120), an upper bushing (130), a contact pin (150), and a vibration detection unit (170) are arranged and configured in appropriate locations, and a connection anchor (140) is formed to extend to the open upper portion of the housing (110) so as to be connected to the lower surface of the main body (10).

[0043] The lower bushing (120) and the upper bushing (130) are configured to absorb, disperse, and buffer lateral vibrations due to horizontal ground motion, respectively, and have the same specific structure, but differ only in their placement positions.

[0044] For example, the lower bushing (120) can be installed on the inner lower part of the housing (110), and at this time, since the buffer part (160), the vibration detection part (170), the upper bushing (130), etc. are installed in a vertically connected manner on the lower bushing (120), it is preferable that the lower bushing (120) be fixedly installed at the exact center of the inner bottom surface of the housing (110) so as to have a fixed structure that does not move inside the housing (110).

[0045] The lower bushing (120) can be made entirely of elastic material such as rubber or silicone, and has a specific structure in which a plurality of first buffer rings (122) in a circular ring shape are formed concentrically and offset by a certain distance below a first support pad (121) of a certain area.

[0046] That is, when a transverse vibration is applied to the lower bushing (120), each of the first buffer rings (122) arranged concentrically is induced to elastically deform appropriately in the space between them spaced apart from each other by the transverse vibration, thereby gradually offsetting the external impact. In addition, each of the first buffer rings (122) has a structure that can easily absorb and process longitudinal vibration to a certain extent due to its structure that is easy to compressively deform and restore due to compressive force.

[0047] A first spring support member (123) of a certain height may be formed to extend upward on the upper surface of the lower bushing (120), preferably at the center of the first support pad (121), and the first spring support member (123) is inserted into the lower spring (161) of the buffer member (160) to be described later to prevent the lower spring (161) from being dislocated at the end.

[0048] Next, the upper bushing (130) is identical in all structures to the aforementioned lower bushing (120), and differs only in that it is not fixed to the housing (110) side but is fixed to the main body (10) side and is positioned on the inner upper part of the housing (110).

[0049] For example, the upper bushing (130) may be made entirely of elastic material such as rubber or silicone, and has a specific structure in which a plurality of second buffer rings (132) in a circular ring shape are formed concentrically and offset by a certain distance on a second support pad (131) of a certain area.

[0050] That is, when transverse vibration is applied to the upper bushing (130), each of the second buffer rings (132) arranged concentrically is induced to elastically deform appropriately in the space between them spaced apart from each other by the transverse vibration, thereby gradually offsetting the external impact. In addition, each of the second buffer rings (132) has a structure that can easily absorb and process longitudinal vibration to a certain extent due to its structure that is easy to deform and restore due to compression force.

[0051] A second spring support member (133) of a certain height may be formed to extend downwardly on the lower surface of the upper bushing (130), preferably at the center of the second support pad (131), and the second spring support member (133) is inserted into the upper spring (162) of the buffer member (160) to be described later to prevent the upper spring (162) from being dislocated at the end.

[0052] The connecting anchor (140) is configured to connect the center of the upper bushing (130) and the lower surface of the main body (10). The lower surface is connected to the exact center of the upper bushing (130), and the upper surface penetrates the lower surface of the main body (10). In addition, a nut is fastened around the upper surface that penetrates the lower surface of the main body (10) so that the position can be fixed on the main body (10).

[0053] Next, the contact pin (150) may be formed protrudingly on the inner surface of the housing (110) and may be made of a conductor capable of conducting electricity so that an electrical contact can be formed when the vibration detection unit (170) comes into contact with the vibration detection unit (170) according to the eccentric movement of the vibration detection unit (170) described later.

[0054] The contact pins (150) can be arranged in a plurality of equal intervals along the inner circumference of the housing (110) so that even if the vibration detection unit (170) moves eccentrically in an irregular direction within the housing (110), it can induce contact with the contact pins (150) over a wider range.

[0055] Next, the vibration detection unit (170) is installed between the lower bushing (120) and the upper bushing (130) through the buffer unit (160) and is arranged to be able to move eccentrically inside the housing (110) when vibration due to an earthquake is applied.

[0056] When the vibration detection unit (170) that has moved eccentrically toward the inner surface of the housing (110) due to vibration comes into contact with the contact pin (150) and a contact is generated, the vibration detection unit (170) can detect this and generate an earthquake detection signal.

[0057] Before a specific description of the vibration detection unit (170), the buffer unit (160) is configured to induce eccentric movement by linking the vibration detection unit (170) placed between the lower bushing (120) and the upper bushing (130) to the vibration transmitted by an earthquake, while absorbing, dispersing, and buffering longitudinal vibration caused by vertical ground motion, and may include a lower spring (161) installed between the lower bushing (120) and the vibration detection unit (170) and an upper spring (162) installed between the upper bushing (130) and the vibration detection unit (170).

[0058] That is, the buffer unit (160) can be largely composed of a lower spring (161) and an upper spring (162), and the lower spring (161) and the upper spring (162) can have a structure in which they are not integrally configured but are segmented from each other at the point of the vibration detection unit (170), and the upper end of the lower spring (161) is fixed to the vibration detection unit (170), and the lower end of the upper spring (162) is fixed to the vibration detection unit (170).

[0059] Accordingly, the vibration detection unit (170) can be made to react more intuitively to vibration. However, if the lower spring (161) and the upper spring (162) are configured as a single integral body and the vibration detection unit (170) is installed at the midpoint thereof, the vibration detection unit (170) requires bending deformation of the middle part of the integral spring in order for the vibration detection unit (170) to move eccentrically and come into contact with the contact pin (150). On the other hand, if this integral buffer unit (160) is made of a conventional coil spring, it becomes a structure that is somewhat disadvantageous in inducing eccentric movement of the vibration detection unit (170).

[0060] The lower spring (161) and the upper spring (162) are formed with a conventional coil spring structure, but are arranged in the same vertical line with a vibration detection unit (170) interposed between each connecting point, so that they can perform the function of buffering lateral vibration.

[0061] Next, the vibration detection unit (170) is positioned at the exact center of the housing (110) and is spaced apart from the inner surface of the housing (110). When vibration due to an earthquake is applied, it moves eccentrically toward the inner surface of the housing (110) between the lower spring (161) and the upper spring (162) and comes into contact with the contact pin (150), thereby generating an earthquake detection signal.

[0062] That is, the vibration detection unit (170) is basically a means to monitor in real time whether an earthquake occurs around the area where the distribution panel is installed so that follow-up measures can be taken quickly in response to the earthquake.

[0063] More specifically, the vibration detection unit (170) can be broadly exemplified as including a support ring (171), an external electrode (172), and an internal electrode (173).

[0064] First, the support ring (171) is formed in a ring shape and is configured to connect the upper part of the lower spring (161) and the lower part of the upper spring (162), respectively.

[0065] The upper end of the lower spring (161) and the lower end of the upper spring (162) are each formed as free ends, but can be connected and fixed by welding to the inner surface of the support ring (171) or by using a separate fixing bracket.

[0066] The support ring (171) constitutes the overall skeleton of the vibration detection unit (170), and an external electrode (172) can be attached and installed to the outside of the support ring (171) and an internal electrode (173) can be attached and installed to the inside, while the support ring (171) can be formed entirely or partially as a non-conductor for the purpose of preventing short circuits and insulating the external electrode (172) and the internal electrode (173), and can support the external electrode (172) and the internal electrode (173) while being spaced apart from each other.

[0067] As an example, the support ring (171) may be exemplified by including a core ring (171a) that wraps the connection point between the upper end of the lower spring (161) and the upper spring (162) to the outside, and an attachment ring (171b) that is formed to extend to the upper and lower ends of the core ring (171a) with a thickness thinner than the thickness of the core ring (171a).

[0068] The coring (171a) is a configuration that provides the overall rigidity of the support ring (171), and the attachment ring (171b) provides an attachment point for the external electrode (172) and the internal electrode (173), but in some cases, it can be configured to be relatively thinner than the coring (171a) so that it can be easily penetrated by the contact pin (150).

[0069] For example, the core ring (171a) and the attachment ring (171b) can be combined and configured using different materials. The core ring (171a) can be made of a metal material, and the attachment ring (171b) can be made of a synthetic resin material that has an insulating function and is easy to arbitrarily punch.

[0070] The core ring (171a) and the attachment ring (171b) may have predetermined steps formed in the outer and inner surfaces of the attachment ring (171b) due to the difference in thickness, and the outer electrode (172) and the inner electrode (173) may be respectively fixedly connected to these steps.

[0071] The external electrode (172) and the internal electrode (173) are configured to operate by detecting a change in electrostatic capacitance that occurs when a specific object comes into contact, and are each electrically connected to a control unit (not shown) to receive a microcurrent and are in a standby state, and when in contact with a contact pin (150), the output value can be output as an earthquake detection signal.

[0072] The external electrode (172) is installed in a ring shape that follows the outer surface of the support ring (171), more specifically, on the outer side of the attachment ring (171b), and can generate a first earthquake detection signal when it comes into contact with the contact pin (150).

[0073] The inner electrode (173) is installed in a ring shape that follows the inner surface of the support ring (171), preferably attached to the inner surface of the support ring (171), and preferably to the inner side of the attachment ring (171b), and can generate a second earthquake detection signal separate from the first earthquake detection signal when in contact with the contact pin (150).

[0074] The external electrode (172) and the internal electrode (173) are formed by rolling a metal sheet in a circular shape in the shape of a belt. In particular, in the case of the external electrode (172), when the contact pin (150) is strongly impacted, the contact pin (150) can penetrate the external electrode (172).

[0075] The external electrode (172) is arranged on the outer surface of the support ring (171) so that it can relatively easily contact the contact pin (150) when the vibration detection unit (170) moves eccentrically, and the internal electrode (173) is arranged on the same horizontal plane as the external electrode (172), but can be arranged at a point where any contact with the contact pin (150) is limited in a line where the contact pin (150) does not simultaneously penetrate the external electrode (172) and the attachment ring (171b).

[0076] In other words, the structure is such that the external electrode (172), the attachment ring (171b), and the internal electrode (173) are arranged in a row from the outside to the inside, and when a relatively weak vibration due to an earthquake is transmitted to the damper (100), the vibration detection unit (170) moves eccentrically toward the contact pin (150) so that only the external electrode (172), which is the outermost component, can lightly contact it, and thus the first earthquake detection signal can be detected.

[0077] Conversely, when a strong vibration due to a relatively strong earthquake is transmitted to the damper (100), the vibration detection unit (170) moves eccentrically with a strong force toward the contact pin (150) to apply an impact, and at this time, the contact pin (150) can continuously penetrate the external electrode (172) and the attachment ring (171b) arranged in a row from the outside to the inside to form a contact point with the internal electrode (173). Accordingly, a second earthquake detection signal can be detected at the internal electrode (173).

[0078] At this time, it is preferable that the contact pin (150) be formed into a sharp cone structure so that it can simultaneously penetrate the external electrode (172) and the attachment ring (171b) of the support ring (171) to form a contact point with the internal electrode (173), and accordingly, a structure is provided in which the contact pin (150) can more easily form a contact point with the internal electrode (173) by penetrating the continuous external electrode (172) and attachment ring (171b) when a strong earthquake occurs.

[0079] The external electrode (172) and internal electrode (173) described above are the concept of a conventional electrostatic capacitance touch sensor that detects surface electromotive force when an object is touched through charging / discharging of a capacitor, and thus a detailed description thereof is omitted as it follows the known content.

[0080] Meanwhile, when each earthquake detection signal is detected from the external electrode (172) and the internal electrode (173), the control unit notifies the relevant organizations, such as the fire department and facility manager, of the current situation in real time based on the earthquake detection signal so that follow-up measures for the safety of the distribution panel can be quickly taken, and further, the control unit suppresses the occurrence of a fire inside the main body (10) due to damage to the distribution device caused by the earthquake shock, thereby preventing a large-scale disaster caused by damage to high-voltage power equipment and damage to people and property in the distribution station.

[0081] In addition, the control unit can analyze the intensity of the earthquake based on the first earthquake detection signal and the second earthquake detection signal. For example, if only the first earthquake detection signal is output, it can be determined as a relatively weak earthquake, and if the second earthquake detection signal is output, it can be determined as a relatively strong earthquake, allowing the safety measures of the distribution panel to be raised.

[0082] Additionally, the control unit can count the number of times an earthquake detection signal is detected and, based on this, can provide information for analyzing the earthquake occurrence cycle and pattern.

[0083] In particular, since permanent damage to the internal electrode (173) occurs when a strong earthquake occurs, it is possible to forcibly replace the detailed parts of the damper (100) with new parts, thereby providing the advantage of improving the operational reliability of the damper (100).

[0084] Meanwhile, in the event of a fire occurring in various cases, such as a fire caused by a chain reaction of the aforementioned earthquake, a fire caused by a defect in a power distribution device, or a fire caused by a natural disaster such as a forest fire, a fire extinguishing unit (200) that sprays a fire extinguishing agent inside the main body (10) may be installed inside the main body (10) to extinguish the fire.

[0085] The fire extinguishing unit (200) is configured to prevent the spread of fire by spraying a fire extinguishing agent over a uniform range when a fire occurs inside the main body (10), and can be broadly exemplified as including a profile (210), a first fire extinguishing means (220), a first support member (230), a second fire extinguishing means (240), and a second support member (250).

[0086] First, the profile (210) constitutes the overall skeleton of the digestive unit (200) and accommodates the first digestive means (220), the first support member (230), the second digestive means (240), and the second support member (250) inside, and forms a passage for the digestive agent to move when the digestive agent is activated.

[0087] The profile (210) is composed of a plurality of vertical tubular members (211) spaced apart in the front, back, left, and right directions to form a square frame structure corresponding to the corner points inside the main body (10) and a plurality of horizontal tubular members (212) connecting the top and bottom of the plurality of vertical tubular members (211), so that it can have a structure shape corresponding to the corners of a hexahedron.

[0088] A distribution device can be placed at the exact center of the profile (210) prepared in this manner.

[0089] Each vertical tubular member (211) and horizontal tubular member (212) may have a plurality of injection holes (213) formed along the longitudinal direction, and the fire extinguishing agent may be sprayed to the outside, preferably to the internal space of the main body (10), through the injection holes (213).

[0090] The first fire extinguishing means (220) is configured to provide a fire extinguishing agent and can be placed on the inner upper portion of at least one vertical tubular member (211) among a plurality of vertical tubular members (211).

[0091] At this time, the first support member (230) can support the first fire extinguishing means (220) at a certain height inside the vertical tubular member (211).

[0092] The first fire extinguishing means (220) may be a throwable fire extinguisher with a fire extinguishing agent loaded inside a case made of a material that can be arbitrarily broken by a falling impact.

[0093] When the first fire extinguishing means (220) is damaged by free fall within the vertical tubular member (211), the fire extinguishing agent loaded in the first fire extinguishing means (220) spreads within the vertical tubular member (211) and horizontal tubular member (212) that are connected to each other, becomes activated throughout the entire inner portion of the profile (210), and then flows out through each injection hole (213) to extinguish the fire.

[0094] The first support member (230) may use a shape memory alloy that is deformed into a form that allows the first fire extinguishing means (220) to fall freely when heat is transferred due to a fire.

[0095] That is, when a fire occurs, the first support member (230) can be deformed into a predetermined shape and cause the first fire extinguishing means (220) that it was supporting to fall freely.

[0096] One end of the first support member (230) is fixed to the inner surface of the vertical tubular member (211), and the other end is formed in the form of a free end, and is structured to be able to support the first fire extinguishing means (220) thereon. As the other end, which is the free end, bends downwards according to heat transfer, the first fire extinguishing means (220) that was being supported can fall freely downwards.

[0097] In addition, a damage-inducing projection (214) is provided at the bottom of the vertical tubular member (211) to induce arbitrary damage of the first fire extinguishing means (220) implemented as a dropped throwable fire extinguisher, so that the first fire extinguishing means (220) can be more easily induced to be damaged.

[0098] The second fire extinguishing means (240) may be implemented as a throwable fire extinguisher identical to the first fire extinguishing means (220) described above, or may be implemented in a different manner, for example, using a conventional pressurized fire extinguisher.

[0099] As in the description of the first fire extinguishing means (220) and the first support member (230) described above, the second fire extinguishing means (240) can be arranged on the inner upper part of a vertical tubular member (211) in which the first fire extinguishing means (220) is not built among the plurality of vertical tubular members (211), and the second support member (250) can use a shape memory alloy that supports the second fire extinguishing means (240) at a certain height within the vertical tubular member (211), but is deformed to allow the supported second fire extinguishing means (240) to fall freely when heat is transferred due to a fire.

[0100] At this time, the second fire extinguishing means (240) of the pressurized fire extinguisher structure can be arranged in a direction in which the lever faces downward, and in the case of a safety pin, it is fixed to the inner wall surface of the vertical tubular member (211) so that when the second fire extinguishing means (240) falls freely due to deformation of the second support member (250), it can be naturally removed from the lever.

[0101] When the second support member (250) is deformed and the second fire extinguishing means (240) is allowed to fall freely, the lever of the second fire extinguishing means (240) is pressed against the lower surface of the vertical tubular member (211), and the fire extinguishing agent compressed and stored in the bomb is sprayed with strong pressure to fill the inside of the profile (210). At the same time, the fire extinguishing agent spread with such strong pressure spreads relatively quickly compared to the aforementioned throwable fire extinguisher, and can be uniformly sprayed to the outside through the spray hole (213).

[0102] At the location where the aforementioned damage-inducing protrusion (214) is formed, a pressing plate (214) may be provided so that the lever of the second fire extinguishing means (240) can be easily pressed.

[0103] The second support member (250) may have the same structure as the first support member (230) described above, and the first support member (230) and the second support member (250) may use easily melted lead in some cases.

[0104] As another embodiment using the second fire extinguishing means (240) of the pressurized fire extinguisher structure, as shown in FIGS. 14 and 15, a pair of spring hinges (260) are installed facing each other symmetrically on the pipe of the vertical tubular member (211).

[0105] A pair of spring hinges (260) are rotatably connected at one end to the inner wall of a vertical tubular member (211) and at the other end are free ends. When the ends are arranged to face each other, they are arranged so as to roughly close the pipe of the vertical tubular member (211).

[0106] At this time, a coil spring (262) is coupled to a rotary pin (261) of each spring hinge (260) so that the other end of each spring hinge (260) can be elastically pulled in a direction facing each other, and a stopper can be provided on the upper part of the spring hinge (260) to prevent excessive rotation of the spring hinge (260).

[0107] Accordingly, each spring hinge (260) is arranged parallel to each other on the same line so as to roughly close the vertical tubular member (211) pipe, and when the second fire extinguishing means (240) falls freely and passes the point of the spring hinge (260), each spring hinge (260) operates to open the pipe by rotating to allow the second fire extinguishing means (240) to pass through.

[0108] At the bottom of the vertical tubular member (211), a cup (263) in the shape of a container with an open top to accommodate the bottom of the second fire extinguishing means (240) is provided, and when the lever of the second fire extinguishing means (240) passing through the spring hinge (260) is pressed within the cup (263), the fire extinguishing agent compressed and stored in the bomb is sprayed with strong pressure, so that the fire extinguishing agent can be sprayed into the inside of the profile (210) along the distribution pipe (264) extended from the cup (263).

[0109] In addition, a hook (241) is formed protrudingly on the upper end of the second fire extinguishing means (240) so that the other end of the spring hinge (260) is hooked and supported, and the other end of each spring hinge (260) is hooked and supported by the hook (241) of the second fire extinguishing means (240), thereby restricting rotation and suppressing the upper movement of the second fire extinguishing means (240), so that the extinguishing agent can be intuitively sprayed when the lever is pressed with stronger pressure.

[0110] Meanwhile, the distribution board according to the present invention may further include a sensor unit (20) attached and installed inside the main body (10) to detect fire, and the sensor unit (20) includes sensors such as a heat detection sensor, a gas detection sensor, and a flame detection sensor.

[0111] A heat sensor can detect fire by measuring heat rays emitted from a flame. Generally, heat sensors are classified as temperature sensors, and are divided into contact types that detect temperature through direct contact and non-contact types that measure emitted heat rays. Here, temperature sensors can use thermistors, thermosensitive resistors, thermocouples, crystal oscillators, pyroelectric infrared sensors, IC temperature sensors, transistors, phototubes, diodes, photodiodes, phototransistors, shape memory alloys (SMA), thermosensitive ferrites, mercury thermometers, quantum infrared sensors, etc.

[0112] A gas detection sensor measures the components of gas and detects fire based on the amount of a specific gas component. In this embodiment, it is assumed that it measures carbon monoxide, carbon dioxide, etc., but it is not limited thereto, and any one of the harmful gases generated during the combustion process when a fire occurs can be detected.

[0113] Here, gas detection sensors vary in type and concentration depending on the gas type and concentration. Generally, they are composed of contact combustion sensors, semiconductor sensors, ceramic gas sensors, etc., and electrochemical methods (solution conduction method, potentiostatic electrolysis method, diaphragm approach), optical methods (infrared absorption method, visible absorption method, optical interference method), electrical methods (hydrogen ionization method, thermal conductivity method, contact combustion method, semiconductor method), gas chromatography method, etc. can be used.

[0114] Flame detection sensors generally use optical sensors, and generate detection signals by measuring the amount of light emitted by a flame, the shape or state of the flame, the movement of the flame, or the movement of smoke. Flame detection sensors can convert light itself or information contained in light into electrical signals by using photoelectric conversion principles such as the photoelectric effect, photoconductive effect, photoelectromotive effect, and pyroelectric effect, and photoconductive cells, photodiodes, phototransistors, LASCRs, CCD image sensors, MOS image sensors, photothyristors, photoelectric multipliers, phototubes, photocouplers, color sensors, PSDs, fiber sensors, infrared sensors, and ultraviolet sensors can be used.

[0115] The detection results of the sensor unit (20) can be transmitted to the control unit, and the control unit notifies the relevant organization so that a response to the fire can be made quickly.

[0116] In summary, the distribution board according to the present invention provides a vibration-proof function for external shocks applied in various directions due to ground movement when an earthquake occurs, thereby preventing damage and malfunction due to the shock, and furthermore, by detecting and monitoring in real time whether an earthquake has occurred, the occurrence cycle, the magnitude of the shock, etc., it enables rapid follow-up measures to be taken to protect the distribution board from an earthquake phenomenon, and furthermore, it enables the detected information to be utilized as information data for establishing measures to prevent damage to the distribution board due to an earthquake, and it provides the advantageous effect of preventing damage to high-voltage power equipment and large-scale disasters in distribution equipment that may occur due to a fire accident caused by an unforeseen reason.

[0117] The embodiments of the present invention described above are merely exemplary, and those skilled in the art will readily appreciate that various modifications and equivalent other embodiments are possible. Therefore, it will be readily understood that the present invention is not limited to the forms mentioned in the detailed description above. Accordingly, the true technical protection scope of the present invention should be defined by the technical spirit of the appended claims. Furthermore, the present invention should be understood to include all modifications, equivalents, and alternatives within the spirit and scope of the present invention as defined by the appended claims.
