Fault detector for communication engineering overhead cable

Abstract

The invention discloses a fault detector for a communication engineering overhead cable. The fault detector comprises an insulating housing. A touch screen and a key control panel are inlaid in the upper and lower parts of the front surface of the insulating housing respectively. The inner top of the insulating housing is fixedly connected with a GPS positioner. A current transformer is fixedly connected to the central position of the inner bottom of the insulating housing and comprises a first winding, a second winding and an iron core. Coils are wound around the surfaces of the first windingand the second winding. The number of turns of the coil wound around the first winding is less than the number of turns of the coil wound around the second winding. Both the left and right sides of the current transformer are equipped with a surge protector. A digital-to-analog converter is arranged on a middle position over the surge protectors. A PLC is inlaid over the digital-to-analog converter. The fault detector has the advantages of safety protection, convenient detection and high detection and maintenance efficiency by means of the current transformer, the GPS positioner, the surge protectors, the insulating housing and the PLC.

Description

technical field [0001] The technical field of communication engineering of the present invention is specifically a fault detection device for communication engineering overhead cables. Background technique [0002] Communication engineering (also known as: information engineering, telecommunications engineering. Formerly known as: long-distance communication engineering, weak current engineering) communication engineering is an important branch of electronic engineering and one of the basic disciplines. This discipline focuses on information transmission in the communication process The principle and application of signal processing, the research of communication engineering is to transmit information from the sending end (source) to one or more receiving ends (sink) in the form of electromagnetic waves, sound waves or light waves through electrical pulses, and the receiving end can Whether the information can be correctly identified depends on the loss in transmission.
