Abstract
Electric leakage self -checking cable support, mainly by the base, stand and a plurality of horizontal support are constituteed, the stand sets up in the middle of the base, horizontal support symmetry is fixed in the stand both sides, the stand is U shaped steel stand, set up the voltage detector that is qualified for the next round of competitions on the U shaped steel stand, controller and wifi send the ware, set up the zero sequence current detector on every horizontal support respectively, the zero sequence current detector links to each other with the controller, it is continuous with power operating personnel's smart machine that the controller sends the ware through wifi, the voltage detector that is qualified for the next round of competitions includes optoelectronic isolation ware and digital analog converter, the voltage detector that is qualified for the next round of competitions links to each other with the controller. The utility model discloses set up on the cable support by zero sequence current detector and the leakage detection mechanism that the voltage detector that is qualified for the next round of competitions constitutes, realized that electric cable frame to cable leakage detection and warning, has simple structure, convenient to use and safe and reliable's advantage.
Description
Technical field
This utility model is related to a kind of cable bearer and in particular to a kind of electric leakage self-inspection cable bearer.
Background technology
Cable bearer typically angle bar section bar is welded or securing member connection splicing dress forms, cable bearer is widely used in the engineerings such as various projects of transmitting and converting electricity, transformer station, subway tunnel, cable is in use once drain conditions, it will bring great potential safety hazard to neighbouring personnel.
Utility model content
This utility model provides a kind of electric leakage self-inspection cable bearer, cable leakage cannot be detected with the cable bearer solving the problems, such as prior art presence.
This utility model is mainly by base, column and some horizontal supports composition, column is arranged in the middle of base, horizontal support is symmetrically fixed on column both sides, solving the employed technical scheme comprise that column of its technical problem is u-shaped steel column, line voltage detector is arranged on u-shaped steel column, controller and wifi transmitter, zero-sequence current detector is respectively provided with each horizontal support, zero-sequence current detector is connected with controller, controller is connected with the smart machine of work about electric power personnel by wifi transmitter, line voltage detector includes photoisolator and digital to analog converter, line voltage detector is connected with controller.
Operation principle of the present utility model is: the zero-sequence current value of the cable on zero-sequence current detector horizontal support is converted to digital signal, it is input in controller, when discovery zero-sequence current value transfinites, meanwhile detect whether line voltage has magnitude of voltage by line voltage detector, by digital to analog converter and photoisolator, line voltage is detected, when voltage has been detected, controller passes through wifi transmitter and sends warning signal to related personnel.
This utility model arranges the detection of electrical leakage mechanism being made up of zero-sequence current detector and line voltage detector on cable bearer it is achieved that cable trough to cable leakage detection and is reported to the police, and has the advantages that structure is simple, easy to use and safe and reliable.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure 1 base, 2u shaped steel column, 3 horizontal supports, 4 line voltage detectors, 5 zero-sequence current detectors, 6 controllers, 7wifi transmitter.
Specific embodiment
As shown in the figure, a kind of electric leakage self-inspection cable bearer, mainly by base 1, column and some horizontal supports 3 form, column is arranged in the middle of base 1, horizontal support 3 is symmetrically fixed on column both sides, column is u-shaped steel column, line voltage detector 4 is arranged on u-shaped steel column 2, controller 6 and wifi transmitter 7, it is respectively provided with zero-sequence current detector 5 on each horizontal support 3, zero-sequence current detector 5 is connected with controller 6, controller 6 is connected with the smart machine of work about electric power personnel by wifi transmitter 7, line voltage detector includes photoisolator and digital to analog converter, line voltage detector 4 is connected with controller 6.
Operation principle of the present utility model is: the zero-sequence current value of the cable on zero-sequence current detector horizontal support is converted to digital signal, it is input in controller, when discovery zero-sequence current value transfinites, meanwhile detect whether line voltage has magnitude of voltage by line voltage detector, by digital to analog converter and photoisolator, line voltage is detected, when voltage has been detected, controller passes through wifi transmitter and sends warning signal to related personnel.
