Description

Cable through pipe with subsidence monitoring function

technical field

The utility model relates to a pipe-through cable with sinking monitoring function.

Background technique

At present, pipe-through cables are widely used in outdoor fields in the field of power transmission and transformation. However, in the field application process, it is found that under the influence of external forces such as ground subsidence, pipe-through cables generally have sinking phenomena, which may easily cause damage to the outer insulation of the cables or damage to the terminals. If the power is loose, it will cause equipment protection malfunction and cause serious economic losses.

But at present, there is no effective means of monitoring the sinking of the cable through the pipe, mainly because the cable through the pipe is a hidden facility, which is difficult to observe, and it cannot be detected in time by relying on human judgment before serious consequences are caused.

Utility model content

The purpose of the utility model is to provide a pipe-through cable with a subsidence monitoring function, which can realize real-time monitoring and alarm of the subsidence of the pipe-through cable.

A pipe-through cable with a subsidence monitoring function, including a connected pipe-through cable body and a junction box. Its special feature is that a micro travel switch is installed outside the junction box. The end is connected with the spare core in the body of the pipe-through cable, and the signal output end of the micro travel switch is connected in series between the DC power supply and the voice alarm module, so that a voice prompt can be issued when the micro travel switch is triggered.

It also includes a warning light, which is connected in parallel with the voice alarm module, and the warning light is installed on the outer surface of the junction box; in addition, the voice alarm module is also installed on the outer surface of the junction box.

Wherein the direct current power supply adopts the battery.

Wherein the signal output end of the micro travel switch is also connected with the remote server through the communication cable.

Among them, the voice alarm module adopts a voice integrated circuit.

Wherein the trigger end of the micro travel switch is connected with the spare core through the connecting wire.

The trial proves that the utility model can realize the effective monitoring of the sinking of the cable through the pipe, which is conducive to early and timely detection of the damage of the outer insulation of the cable or the loosening of the terminal due to the sinking of the cable through the pipe, thereby improving the reliability of the operation of the equipment , to avoid the misoperation of the power system protection device caused by the sinking of the cable through the pipe.

Detailed ways

As shown in Figures 1 and 2, the utility model is a pipe-through cable with sinking monitoring function, which includes a pipe-through cable body 1 connected with a junction box, and a micro travel switch is installed outside the junction box. The trigger end 3 of the micro travel switch is connected to the spare core 2 in the pipe-through cable body 1, and the signal output end of the micro travel switch is connected in series between the DC power supply and the voice alarm module, so that the micro travel A voice prompt will be issued when the limit switch is triggered.

It also includes a warning light, specifically a red LED can be used, the warning light is connected in parallel with the voice alarm module, and the warning light is installed on the outer surface of the junction box; in addition, the voice alarm module is also installed on the outer surface of the junction box , while the DC power supply uses batteries. Voice alarm module adopts voice integrated circuit. The trigger end of the micro travel switch can be connected to the spare core through the connection line, so that the trigger sensitivity can be adjusted only by adjusting the length of the connection line, which is especially suitable for ordinary workers who do not understand the adjustment method of the micro travel switch Simpler and more intuitive.

Wherein the signal output end of the micro travel switch is also connected with the remote server through the communication cable, so that the remote server can perform remote monitoring from different places.

The working principle of the utility model is:

First of all, the trigger end 3 of the micro travel switch is connected to the spare core 2 of the cable body 1 in the normal state, and the micro travel switch is fixed on the junction box connected with the cable body 1, when the cable body is When the relative displacement between 1 and the junction box exceeds the action threshold set by the micro travel switch, the trigger terminal 3 is closed, and the voice integrated circuit and the red LED are respectively energized to send out an alarm sound and light up, thus prompting the staff to sink the cable . The remote server can also be remotely monitored from different places.
