An anti-theft alarm device for power cables to be cast

Abstract

The invention discloses an anti-theft alarm device for a power cable to be put into operation, and relates to the technical field of cable alarm devices. Including power supply module, MCU signal processing module, signal output module, signal receiving module, system self-test and indication module, parameter setting and fault judgment module, fault indication and output module and alarm device; the rectangular square wave sent by MCU signal processing module is After the signal output module, the cable and the signal receiving module, send back to the MCU signal processing module; the MCU signal processing module judges whether there is a broken cable according to this signal, and if there is a broken cable, the stored critical capacitance value is retrieved from the parameter setting unit and Compare and judge the number of the box transformer adjacent to the fault point, and send the judgment result to the fault indication and output module for display, and send an alarm through the alarm device. The invention can carry out anti-theft monitoring on power cables to be put into operation, and has strong versatility, simple structure, low cost and reliable operation.

Description

technical field [0001] The invention relates to the technical field of power cables. Background technique [0002] With the increase of the urban population, most of the new residential quarters are located in the suburbs of the city. During the process of laying cables in the new residential quarters, due to the poor public security environment in the suburbs, the security forces in the quarters are weak, and the power cable equipment needs a certain amount of time from laying to putting into operation. time, resulting in long-term uncharged idle cable equipment. The existing anti-theft devices for cables are all aimed at the anti-theft monitoring of live cable equipment, so that the power cables to be put into operation cannot be monitored, and then the power cables to be put into operation in the newly built community are stolen.

[0002] With the increase of the urban population, most of the new residential quarters are located in the suburbs of the city. During the process of laying cables in the new residential quarters, due to the poor public security environment in the suburbs, the security forces in the quarters are weak, and the power cable equipment needs a certain amount of time from laying to putting into operation. time, resulting in long-term uncharged idle time of cable equipment

However, the existing cable anti-theft devices are all aimed at the anti-theft monitoring of live cable equipment, so that the power cables to be put into operation cannot be monitored, and then the power cables to be put into operation in the newly built residential area are stolen.

It caused great economic losses and seriously affected the progress of cable laying and project acceptance.

Therefore, the anti-theft alarm of the power cables to be put into operation in the newly built residential quarters has become an increasingly serious problem.
