Abstract

The invention relates to a cable fault simulating and positioning system. The cable fault simulating and positioning system comprises a cable fault simulation box, an electrode installing plate, three wire inlet electrodes and three wire outlet electrodes, wherein the electrode installing plate is installed in the cable fault simulation box. The three wire inlet electrodes are connected with three-phase cable cores in a wire inlet cable respectively, and the three wire outlet electrodes are connected with three-phase cable cores in a first wire outlet cable respectively. The cable fault simulation box is internally provided with a resistance box for simulating the break line, low resistance, high resistance and flashover fault between the wire inlet electrodes and the wire outlet electrodes, and the tail end of a second wire outlet cable connected with the wire outlet electrodes is provided with a high-voltage cable terminal. The high-voltage cable terminal is used for connecting a cable fault positioning detecting instrument. The cable fault positioning detecting instrument comprises a central control unit, an impulse transmission circuit, a reflecting receiving circuit and a high speed data collecting circuit, wherein the impulse transmission circuit is used for sending a pulse signal to a tested cable, the reflecting receiving circuit is used for receiving a reflecting signal of the tested signal, and the output end of the reflecting receiving circuit is connected with the input end of the high speed data collecting circuit.

Description

[0001] The application number is: 200910309789.8, and the invention created the name "Cable Fault Simulation and Fault Positioning System". The application date is: the application for the invention patent application on November 16, 2009. Technical field [0002] The invention involves the technical field of personnel training cable failure simulation equipment, which is specifically a kind of personnel training cable failure simulation and fault positioning system. Background technique [0003] Electric power cables (hereinafter referred to as cables) are mostly buried underground. Once a failure occurs, it is very difficult to find. It often takes several hours, or even a few days, which not only wastes a lot of manpower and material resources, but also causes a lot of power loss andSocial impact.How to accurately, quickly, and economically searching for cable failure has become an increasingly concerned issue of the power supply department.The cable failure and the buried envi...
