Description
본 고안은 화재감지용 전선구조에 관한 것으로, 단위길이당 일정한 저항을 갖는 도체 2가닥을 각각 일정온도(열)에서 녹는 수지로 1차 절연피복하고 이를 꼬아서 2차 절연피복한 화재감지용 전선구조에 관한 것이다.The present invention relates to a wire structure for fire detection, wherein the conductors having a constant resistance per unit length are first insulated with a resin that melts at a predetermined temperature (heat) and twisted so that the second insulated coated wire for fire detection It's about structure.
일반적으로 대도시의 전력선, 통신선 등은 지하 공동구(Underground calvert)를 통해 집중적으로 설치되고 있어 만일의 경우, 전선의 용량초과로 인해 화재가 발생될 시에는 무수히 많은 선로의 전력공급 및 통신선로망이 마비되어 산업체의 생산설비가 가동이 중단된다거나, 통신망(전화, 증권망)두절 및 경보체제마비, 수도공급중단 등 재해발생에 따른 사회적 혼란이 야기될 수 있다.In general, power lines and communication lines of large cities are concentrated through underground calverts. In case of fire, power supply and communication line networks of numerous lines are paralyzed when fire occurs due to excess capacity of the wires. Social disruption may occur due to the disruption of the production facilities of the industry, disruption of communication networks (telephones, securities networks), paralysis of alarm systems, and interruption of water supply.
본 고안은 전술한 바와 같은 전선의 용량초과로 인한 화재 및 재해발생에 따른 사회적 혼란을 예방하기 위해 화재발생시 긴급한 복구대처가 용이하도록 전선의 용량초과로 인해 발생한 단락(shot)위치를 정확히 감지할 수 있는 화재감지용 전선구조를 제공함에 그 목적이 있다.The present invention can accurately detect the short-circuit (shot) caused by the excess capacity of the wire to facilitate the emergency recovery measures in the event of a fire in order to prevent social confusion caused by the fire and disaster caused by the excess capacity of the wire as described above. The purpose is to provide a fire detection wire structure.

이하, 본 고안의 실시예를 첨부도면에 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안에 따른 화재감지용 전선구조의 예시도로서, 도시된 바와 같이 단위길이당 일정한 저항을 갖는 도체(1) 2가닥을 각각 일정온도(열)에서 녹는 수지로 1차 절연피복(2)하여 이를 꼬아서 2차 절연피복(2)한 구조로 되어 있다.1 is an exemplary diagram of a wire structure for fire detection according to the present invention, as shown in FIG. 1, two strands of a conductor (1) having a constant resistance per unit length are each melted at a predetermined temperature (heat) with a primary insulating coating ( 2) by twisting it and having a secondary insulation coating (2).
상기 본 고안의 화재감지용 전선구조는 화재의 우려가 있는 선로에 설치하여 직류전원을 인가하되, 단말측이 서로 붙지 않도록 이격시킨 상태에서 서로 전류가 흐르지 않게 하고 화재발생시 선로의 온도(열)가 증가함에 따라 수지(P.P)재로 된 1차 절연피복(3) 및 2차 절연피복(2)이 녹으면서 서로 꼬아져 있는 도체(1)의 탄성력에 의해 도체(1)가 접속되어 회로를 구성함에 따라 전류가 흐르게 되며 이러한, 도체(1)의 단락(shot)에 의해 발생한 단위저항의 양을 통해 화재발생위치를 감지할 수 있도록 한 것이다.The fire detection wire structure of the present invention is installed on a line that may cause a fire, but applies DC power, but does not allow currents to flow in a state in which the terminals are separated from each other so that the current does not flow and the temperature (heat) of the line in the event of fire occurs. As the primary insulation coating (3) and the secondary insulation coating (2) made of resin (PP) melt together, the conductors 1 are connected by the elastic force of the conductors 1 twisted with each other to form a circuit. According to the current flows, it is possible to detect the location of the fire through the amount of unit resistance caused by the short (shot) of the conductor (1).
즉, 단위길이당 도체의 저항이 일정하므로 설치시점으로부터 화재감지위치가 가까우면 회로저항이 작아 많은 량의 전류가 흐를것이며, 화재감지위치가 멀수록 회로저항이 커서 전류량이 적어지는 원리에 따라 알 수 있는 것이다.That is, since the resistance of the conductor per unit length is constant, if the fire detection position is close from the installation point, the circuit resistance is small and a large amount of current will flow. It can be.
예를 들어 100m의 지점에서 숏트발생시 저항은 200Ω가 되므로 화재발생위치를 감지할 수 있는 것이다.For example, when the short occurs at the point of 100m, the resistance becomes 200Ω, so the location of the fire can be detected.
이상 설명한 바와 같이, 본 고안의 화재감지용 전선구조는 화재발생시 선로의 온도가 증가함에 따라 각 절연피복이 녹으면서 서로 꼬아져 있는 도체의 탄성력에 의해 도체가 접속되어 회로를 구성함에 따라 전류가 흐르게 되며, 단위길이당 도체의 저항이 일정하므로 설치시점으로부터 화재감지위치가 가까우면 회로저항이 작아 많은 량의 전류가 흐를것이며, 화재감지위치가 멀수록 회로저항이 커서 전류량이 적어지는 원리에 따라 도체의 단락(shot)에 의해 발생한 단위저항의 양을 통해 화재발생위치를 감지할 수 있는 효과가 있어 전력공급 및 통신망구축을 위한 통신산업상 매우 유용한 고안인 것이다.As described above, the wire structure for fire detection according to the present invention has a current that flows as the conductors are connected by the elastic force of the conductors twisted with each other as the insulation coating melts as the temperature of the line increases in the event of a fire. Since the resistance of the conductor per unit length is constant, if the fire detection position is close from the installation point, the circuit resistance is small and a large amount of current will flow. The farther the fire detection position, the greater the circuit resistance. It is very useful design in the telecommunication industry for power supply and communication network construction because it has the effect of detecting the location of fire through the amount of unit resistance generated by the shot.
