Power cable fault simulation test simulation system

Abstract

The invention relates to a fault simulation and test simulation system for power cables. The fault simulation and test simulation system for the power cables is characterized by comprising a wireless router which can communicate with a host, a cable fault simulation cabinet and a cable fault simulation range finder; the cable fault simulation cabinet includes a cable test terminal cabinet, a cable fault setting cabinet and a cable terminal cabinet; and the cable fault setting cabinet includes a central control unit connected with an A-phase position detection and fault simulation module, a B-phase position detection and fault simulation module and a C-phase position detection and fault simulation module, and the central control unit is connected with a wireless module to facilitate communication of the cable fault simulation cabinet and the wireless router. The system is easy to operate, cable fault types and fault distances can be set at will through software, and common cable faults can be reproduced in a comparatively real way.

Description

technical field [0001] The invention relates to a power cable fault simulation test simulation system. Background technique [0002] With the rapid development of urbanization in the country, underground power cables have been widely used in cities, and there are more and more cable faults. However, the power cable fault testing instrument has relatively high professional requirements for the users. The tester's proficiency in the operation of the power cable fault testing instrument and the identification technology of the fault location waveform have a great influence on whether the cable fault can be detected quickly and accurately. Impact. In order to avoid wasting a lot of manpower and material resources in the process of cable fault detection and reduce the economic loss caused by cable faults, it is very necessary to strengthen the training and assessment of testers and make them proficient in the use of power cable fault testing instruments. [0003] In the past, t...

AI Technical Summary

Problems solved by technology

[0003] In the past, the training of operators of power cable fault testing instruments was to set several fault points of different natures on a real cable, or to use the power cable main insulation fault simulation device (T-GMZ100) produced by Shandong Kehui Power Automation Co., Ltd. and single-core cable sheath fault simulation device (T-GMH100), and then judge the fault type and distance through the connection with the fault test instrument. These methods or equipment have fault points and fault types are fixed, and the number is small, resulting in The knowledge of the trainees is narrow, and the failure testing methods they have mastered are not comprehensive enough; it is easy for the trainees to remember the types and distances of these fault points during the training, and it is impossible to really test the knowledge of the trainees during the training assessment or skill competition
