Description

Underground power distribution line fixing device for fast fire check {UNDERGROUND LINE FIXING DEVICE TO DETECT OF FAST FIRE}

The present invention relates to a underground distribution line fixing device capable of rapid fire confirmation.

In general, China's overhead distribution line was started by relocating the main street along the main street to the back alley and supplying nearby customers from the columnar transformer using low voltage cables.

Subsequently, most power ports passing through the city underground are connected to power lines and communication lines. In particular, underground cables that are connected through underground power outlets are connected at regular distances.

However, the risk of fire is considerably high in these connectors, and in fact, many fires have occurred, causing enormous damage. The existing installed linear detectors, smoke, and flame detectors are alerted only after a certain time after the fire occurs. This is impossible and poses a great threat to fire safety.

15 is a view illustrating a short circuit check of the underground distribution line fixing apparatus capable of confirming a rapid fire according to the present invention.

When a short circuit occurs due to a cover damage of the underground distribution line L or a crack of the outer body 110, the ground fault detecting sensor 60 detects the ground fault signal and outputs a ground fault detection signal to the controller 70. Receives a ground fault detection signal to the ground fault detection sensor 60 to control the light unit 90, the light unit 90 is controlled by the control unit 70 so that the operator can intuitively recognize the current situation. It emits yellow light.

According to the present embodiment, when a fire or a short circuit occurs in the power outlet 10, the fire sensor 50 or the ground fault sensor 60 immediately detects the fire and extinguishes the fire as well as the worker's current situation. By emitting a specific color of light, the operator is able to pinpoint the current situation, so that the next follow-up can be proceeded quickly, thus preventing further damage.

In addition, in the present invention, the height (length) of the coupling groove 115 of the connector 100 is equal to the height of the coupling protrusion 42a of the adapter 40, but the width (width) of the coupling groove 115 is Since the connector 100 is formed to be relatively longer than the width of the coupling protrusion 42a, the connector 100 can be slid along the longitudinal direction of the underground distribution line L even when the connector 100 is fixed to the adapter 40. Accordingly, the underground distribution line Even though the tensile force is applied to (L), the connector 100 slides to accommodate the same, so that the underground distribution line L is prevented from being separated from the connector 100.

In addition, the present invention by electrically pressing the pusher button 130 by elastically converting the plate spring 140 by electrically connecting and fixing the connection terminal 120 introduced into the interior through both ends of the outer body 110, On the contrary, since the electrical connection state and the fixed state can be released, there is an advantage that anyone can easily and conveniently work.

In addition, the present invention has a relatively simple structure has the advantage of easy manufacturing.

The detailed description of the present invention described above has been described with reference to the preferred embodiments of the present invention, so those skilled in the art or those skilled in the art will have the idea of the present invention described in the claims to be described later. And it will be understood that various modifications and changes of the present invention can be made without departing from the scope of the art.
