A high-voltage cable outer sheath fault finding simulation teaching device

Abstract

A high voltage cable outer sheath troubleshooting simulation teaching device comprises a platform (19). The platform (19) is divided into four areas which are a crossover interconnection box and direct grounding box simulation area (I), an A phase line area (II), a B phase line area (III) and a C phase line area (IV). An epoxy resin film is pasted on a steel sheet so as to construct the platform possessing relative hardness and simultaneously enough insulating performance is guaranteed. According to a distribution condition of parts, a port is arranged on the platform so that the platform is detachable, is convenient to carry and is easy to put away and store. A semi-conductive tape and an insulated rubber tape are used to wind an electric wire according to a certain rule, an insulating layer of a real cable and a semiconductor layer structure are simulated, and an opening is arranged at a correlation position so as to manufacture grounding simulation and a grounding fault.

Description

technical field [0001] The invention belongs to the electric power industry and belongs to the technical field of high-voltage cable outer sheath fault finding simulation teaching technology, and in particular relates to a high-voltage cable outer sheath fault finding simulation teaching device. Background technique [0002] With the development of urbanization, it is becoming a new trend for the electric power industry to adapt to urban development for high-voltage overhead lines to be used as cables. With the lengthening of the cable operation and maintenance line distance and the expansion of the scope, the failure of the outer sheath of the high-voltage cable is becoming more and more frequent, which is no different from the fault finding technology for the cable operation and maintenance personnel and the training and construction of the cable operation and maintenance backup team New requirements were put forward. [0003] In the process of finding faults in the outer...

Problems solved by technology

[0003] In the process of finding faults in the outer sheath of high-voltage cables, various instruments such as high-voltage bridges, cable fault location power supplies, and step voltage indicators are involved. At the same time, the bridge method, voltage drop method, step voltage method, and potential Various methods such as the comparison method are a test for the learning and mastering ability of the operation and maintenance personnel, and there is a lack of a unified and comprehensive teaching opportunity in the daily training, which makes the staff's skills in the troubleshooting of the outer sheath vary. It is difficult to effectively cultivate mature technical personnel in fault finding. At the same time, the real-time fault teaching is faced with the uncertainty of fault occurrence. It is difficult to carry out the training of personnel regularly, which makes the rare accumulated skills become rusty.

[0004] In the face of the above problems, in traditional teaching, the unified teaching of personnel is often achieved by building real-world sites and restoring fault scenarios. However, the huge land lease costs and fault scene restoration costs make it difficult for small and medium-sized cable operation and maintenance companies to afford. It is difficult to popularize. In the face of the increasingly frequent failures of the outer sheath of high-voltage cables, real-life teaching is faced with the dilemma of heavy burden and difficult promotion. For this, we urgently need an efficient, comprehensive, concise and practical teaching device
