Description

Distribution board preparing fire and vibration {Distribution board preparing fire and vibration}

The present invention relates to a switchboard that minimizes fatal accidents such as power outages due to fire and vibration, and more particularly, to a switchboard that detects power outages caused by vibration as well as fire at an early stage and minimizes damage.

A switchboard is a device that constantly inserts and manages switches, instruments, and relays (relays) for the operation or control of power plants and substations, and the operation of motors.

This switchboard is an essential device installed in any facility that uses electricity and is usually protected by a cabinet.

However, since the switchboard is an essential device for supplying electricity and is closely related to social infrastructure, if electricity supply is interrupted even for a moment, it can lead to a series of major accidents. Therefore, the role of the switchboard and accident prevention are very important.

In general, a switchboard is installed in a cabinet and has a fan to cool the heat or a firefighting equipment nearby to extinguish a fire, but there is no other safety device. In addition, the electrical safety manager directly checks and manages whether the switchboard is overheated with a heat detector such as an infrared detector from time to time.

Recently, earthquakes have occurred all over the world due to climate change, and Korea is no exception. These natural disasters damage switchboards and switchboards, causing not only power outages but also human casualties. However, a device or method capable of promptly detecting and responding to earthquake and fire damage at the same time is insufficient.

1 and 2, the center pin 110 protrudes at the uppermost end of the arcuate weight 100, and an arcuate inner groove 111 is formed inside, and a plurality of contact protrusions 120 are constant on the edge of the lower surface. formed at intervals. Here, the arcuate weight 100 is a conductor.

The arcuate weight 100 is thicker toward the lower end, so it is preferable that the center of gravity exists at the lower end.

And the tip of the core pin 200 is located at the top of the inner groove 111.

Since the center of gravity of the arcuate weight 100 is at the lower end, even if the arcuate weight 100 is shaken by an external force, it is possible to stand upright around the core pin 200 in the end.

In addition, a screw groove 320 is formed on one side of the horizontal support 300, the lower end of the core pin 200 is installed on the upper surface, and the contact protrusion 120 electrically contacts the ring-shaped electrode pattern on the bottom surface. 310 is formed and leads to the screw groove 320.

That is, a case may occur when the contact protrusion 120 touches the electrode pattern 310 while the arch-shaped weight 100 is shaken by vibration or other external force. In this case, it can be determined that an event of vibration or fire has occurred.

A groove 457 is formed on the lower inner surface of the battery groove 440, and an intermediate electrode 480 is formed to electrically conduct from the spitter groove to the screw hole 470.

That is, the top electrode 420, the side electrode 430, the speaker 490, and the intermediate electrode 480 of the vertical support 400 are electrically connected via a coin battery.

In addition, the graphene bridge 500 is inserted into the copper piece 510 formed at both ends of the electrode pin 410 and the center pin 110, and the copper pieces 510 at both ends are connected by a graphene thin film 520 It is good.

3 is a diagram showing steps of manufacturing the graphene bridge 500 of the detection device 10 for detecting fire and vibration included in the switchboard 20 in preparation for fire and vibration of the present invention.

As shown in FIG. 5 , when vibration occurs and the horizontal support 300 is shaken, the arcuate weight 100 is also shaken, and then the contact protrusion 120 may come into contact with the electrode pattern 310 . Therefore, the contact protrusion 120, the arcuate weight 100, the graphene bridge 500, the top electrode 420, the coin battery 450, the side electrode 430, the speaker 490, the middle electrode 480, the adjustment The screw 600 and the electrode pattern 310 constitute a closed circuit, and when current flows, the speaker 490 operates and sounds.

In addition, the graphene thin film 520 has a negative expansion rate that contracts at high temperatures and expands at low temperatures. In other words, it expands and contracts freely depending on the temperature.

Therefore, the graphene bridge 500 of the present invention contracts at a high temperature, so that the contact protrusion 120 contacts the electrode pattern 310 by inclining the weight 100 as shown in FIG. 5 due to the contraction force. This makes it possible to detect temperature changes.

Meanwhile, even in a non-accident situation, the graphene bridge 500 may be contracted in a high-temperature climate like summer. Therefore, it is good to readjust the separation distance between the horizontal support 300 and the vertical support 400 through the adjusting screw 600 so that the contact protrusion 120 is separated from the electrode pattern 310 in normal times, not in an accident.

In this case, a determination unit 700 capable of determining which of the eight electrodes a current flows may be further provided on the horizontal support 300, and the determination unit 700 selects an electrode through which current is conducted. It is also desirable to perform the role of transmitting it to the outside after classification.

That is, according to the direction in which the vibration occurs, only a specific electrode among the eight electrodes makes electrical contact and distinguishes them, thereby detecting which direction the vibration is. The determination unit 700 may perform a transmission function capable of transmitting such information to the outside as well as a logic circuit capable of determining this.
