Abstract
The utility model relates to a pipe-through cable capable of monitoring sinking. The pipe-through cable comprises a pipe-through cable body (1) and a conjunction box connected with the pipe-through cable body (1); and is characterized in that a micro stroke switch is mounted outside the conjunction box, the trigger end (3) of the micro stroke switch is connected with a standby core (2) in the pipe-through cable body (1), and the signal output end of the micro stroke switch is connected in series between a dc power supply and a voice alarm module, so that the micro stroke switch can emit voice prompt when being triggered. It is provided that sinking of the pipe-through cable can be effectively monitored, and damage on external insulation or loosening of the binding posts due to sinking can be timely discovered at an early stage, thereby improving operational reliability of equipment, and avoiding misoperation of a power system protector caused by sinking of the pipe-through cable.
Description
Technical field
The utility model relates to a kind of poling cable with sinking monitoring function.
Background technology
In power transmission and transformation field, outdoor place has been widely used poling cable at present; but at the scene in application process find be subject to land subsidence sink etc. external force affect; poling cable ubiquity sinkage; easily cause cable external insulation to damage or the stressed loosening and then initiation equipment protection misoperation of connection terminal, cause serious economic loss.
Effectively monitoring poling cable sinking means but there is no at present, is mainly because poling cable is hidden facility, is difficult to observe, and not causing before serious consequence, relies on artificial judgement to find in time.
Utility model content
The purpose of this utility model is to provide a kind of poling cable with sinking monitoring function, can realize poling cable is sunk to carrying out real-time monitoring warning.
A kind of poling cable with sinking monitoring function, comprise the poling cable body and the terminal box that are connected, its special feature is: in described terminal box, micro limit switch is installed outward, the trigger end of this micro limit switch is connected with the core for subsequent use in described poling cable body, and the signal output part of this micro limit switch is connected between direct supply and audio alert module, thereby can in the time that being triggered, send micro limit switch voice message.
Wherein also comprise alarm lamp, this alarm lamp is in parallel with described audio alert module, and this alarm lamp is arranged on terminal box outside surface; Described audio alert module is also arranged on terminal box outside surface in addition.
Wherein direct supply adopts battery.
Wherein the signal output part of micro limit switch is also connected with remote server by telecommunication cable.
Wherein audio alert module adopts speech IC.
Wherein the trigger end of micro limit switch is connected with core for subsequent use by connecting line.
Through probationary certificate; after adopting the utility model, can realize effective monitoring that poling cable is sunk; be conducive to early stage find in time because of poling cable sink to causing cable external insulation to damage or connection terminal stressed loosening; thereby improve equipment operational reliability, avoid the electric system protection device misoperation of sinking to causing because of poling cable.
Brief description of the drawings
Accompanying drawing 1 is principle of work schematic diagram of the present utility model;
Accompanying drawing 2 is logic theory block diagram of the present utility model.
Embodiment
As shown in Figure 1, 2, the utility model is a kind of poling cable with sinking monitoring function, comprise the poling cable body 1 and the terminal box that are connected, in described terminal box, micro limit switch is installed outward, the trigger end 3 of this micro limit switch is connected with the core for subsequent use 2 in described poling cable body 1, and the signal output part of this micro limit switch is connected between direct supply and audio alert module, thereby can in the time that being triggered, send micro limit switch voice message.
Wherein also comprise alarm lamp, specifically can adopt red LED, this alarm lamp is in parallel with described audio alert module, and this alarm lamp is arranged on terminal box outside surface; Described audio alert module is also arranged on terminal box outside surface in addition, and direct supply adopts battery.Audio alert module adopts speech IC.The trigger end of micro limit switch can be connected with core for subsequent use by connecting line, the length that so only need to adjust connecting line is adjustable trigger sensitivity, the common work librarian use that is particularly suitable for not understanding micro limit switch control method, also makes adjustment process more simply more directly perceived.
Wherein the signal output part of micro limit switch is also connected with remote server by telecommunication cable, thereby can make remote server carry out telemonitoring from strange land.
Principle of work of the present utility model is:
First the core for subsequent use of the poling cable body 1 under normal condition 2 places are connected with the trigger end 3 of micro limit switch, and micro limit switch is fixed in the terminal box being connected with poling cable body 1, in the time there is relative displacement between poling cable body 1 and terminal box and exceed the action threshold value of micro limit switch setting, trigger end 3 closures, speech IC and red LED respectively the electric sound that gives the alarm, light, thereby prompting staff cable sinks.Remote server also can carry out from strange land telemonitoring.
