침수방지 및 절연형 지중전선 배전함{Prevention of Underwater and Insulated Type of Underground Cable Distribution Box}Flood control and insulated underground cable distribution box {Prevention of Underwater and Insulated Type of Underground Cable Distribution Box}

본 발명은 지중전선 배전함에 관한 것으로서, 특히, 침수 전에 지중전선 배전함이 승강되는 침수방지 및 절연형 지중전선 배전함에 관한 것이다.The present invention relates to underground cable distribution boxes, and more particularly, to an immersion prevention and insulated underground cable distribution box in which an underground cable distribution box is elevated before flooding.

원격지의 발전소로부터 송전된 전력은 도시의 미관 및 유지보수의 편의성 등의 다양한 장점을 가진 지중전선을 매개로 소비자에게 공급된다. Electric power transmitted from remote power plants is supplied to consumers through underground cables that have various advantages such as urban aesthetics and ease of maintenance.

일반적으로, 지중전선 배전함은, 전력의 배전 및 관리를 용이하게 하기 위해 지중전선으로부터 송전되는 전력을 배분하고 관리하는 배전반과 함체로 이루어져 배전반을 보호하는 하우징으로 이루어진다.In general, the underground cable distribution box is composed of a housing to protect the distribution panel and the distribution panel and the enclosure to distribute and manage the power transmitted from the underground cable to facilitate the distribution and management of power.

이러한 지중전선 배전함은, 관리상의 편의를 위해 지상에 배치되는 것이 일반적인데, 배전함이 전신주에 위치하는 가공전선 구조와는 달리 지중전선은 사람이 통행하는 지상에 지중전선 배전함이 배치되면서, 가공전선보다 지중전선 배전함을 통한 감전사고의 발생가능성을 높이는 문제를 발생시켰다.Such underground cable distribution box is generally disposed on the ground for the convenience of management. Unlike the overhead cable structure in which the distribution box is located on the telephone pole, underground cable distribution box is placed on the ground where people pass, It caused a problem of increasing the possibility of electric shock accident through underground distribution box.

한편, 본 발명에 따른 배전반(D)은 승하강되도록 설치되므로, 이에 따라 베이스(100) 상부에 노출되는 지중전선(W)은 배전반(D)이 승강되어도, 배전반(D)과의 접속이 해제되지 않도록 충분한 여유를 가지고 설치된다.On the other hand, since the switchboard (D) according to the present invention is installed to move up and down, accordingly, even if the switchboard (D) is lifted, the underground wire (W) exposed on the base 100, the connection with the switchboard (D) is released It should be installed with sufficient margin so as not to.

이와 같이 구성된 지중전선 배전함의 작동을 도 2 및 도 3을 참조하여 자세 히 설명하면 다음과 같다.The operation of the underground cable distribution box configured as described above will be described in detail with reference to FIGS. 2 and 3.

우수가 유입되지 않는 평상시에는, 도 2에 도시된 바와 같이, 베이스(100)에 승강플랜지(410)가 밀착배치되는 한편, 우수유입센서(300)는 일정시간마다 우수유입상태를 감지한다. When rainwater is not normally introduced, as shown in FIG. 2, the lifting flange 410 is closely arranged on the base 100, while the rainwater inflow sensor 300 detects the rainwater inflow state every predetermined time.

그런데, 폭우 등으로 인해 우수가 유입되면, 상기 우수유입센서(300)로부터 이상신호가 제어부(400)로 입력된다. 상기 제어부(400)는, 이상신호가 기준횟수 이상, 연속적으로 입력되면 구동모터(210)를 정방향으로 일정시간 동안 작동시킨다. 이때, 상기 구동모터(210)의 작동시간은, 스크류(220)의 높이 및 연장바(520)의 길이에 따라 정해지며, 최고 높이로 승강되어도 스크류(220)가 지지판(530)에 닿지 않도록 설정된다. 따라서, 우수가 유입되어 상기 구동모터(210)가 작동되면, 배전반(D)은 승강되어 침수되지 않는다(도 3).However, when rainwater flows due to heavy rain or the like, an abnormal signal is input from the rainwater inflow sensor 300 to the controller 400. The controller 400 operates the driving motor 210 in a forward direction for a predetermined time when an abnormal signal is continuously input for more than a reference number of times. At this time, the operating time of the drive motor 210 is determined according to the height of the screw 220 and the length of the extension bar 520, and set so that the screw 220 does not touch the support plate 530 even when the lift to the highest height. do. Therefore, when rainwater flows in and the driving motor 210 is operated, the switchboard D is lifted and not flooded (FIG. 3).

그리고, 시간이 흘러 유입된 우수가 완전히 유출되어, 상기 우수감지센서(300)로부터 일정시간 동안 이상신호가 감지되지 않으면, 제어부(400)에서 이를 판단하여 구동모터(210)를 역방향으로 일정시간 동안 회전시켜 지지대(500)를 하강시키면 배전반(D)이 원위치 된다(도 2).In addition, when the rainwater flowing out completely flows out and the abnormal signal is not detected from the rainwater detection sensor 300 for a predetermined time, the control unit 400 determines this and then reverses the driving motor 210 for a predetermined time. Rotating down the support 500, the switchboard (D) is returned to its original position (Fig. 2).

본 발명에 따른 지중전선 배전함은, 상기 우수유입센서로부터 우수유입이 감지되면 구동모터(210)가 작동되어, 배전반(D)을 일정 높이로 승강시키게 되므로, 배전반(D)이 침수되지 않으며, 이로 인해 누전 등이 발생되지 않는 효과가 있다.Underground line distribution box according to the present invention, when rainwater inflow is detected from the rainwater inlet sensor, the driving motor 210 is operated, so as to elevate the switchboard (D) to a certain height, the switchboard (D) is not flooded, so Due to the effect that no short circuit occurs.

또한, 본 발명에 따른 지중전선 배전함은, 유입된 우수가 유출되면, 일정 시 간 후 배전반(D)이 원위치 되므로, 승강기구(200)의 내구성이 좋아져 수명이 증가되는 효과도 예상된다. In addition, the underground cable distribution box according to the present invention, when the rainwater flows out, the switchboard (D) is in place after a certain time, the durability of the elevating mechanism 200 is expected to increase the life is also expected.
