Cable fault analogue simulation system

Abstract

The invention discloses a cable fault analogue simulation system, and relates to the technical field of devices for teaching or training in an electric power system. The system includes a cable, a test end of the cable includes two paths, the first path of the cable test end is connected with a first main terminal of a single-pole three-throw switch K1, the main terminal of the single-pole three-throw switch includes three paths, the first path is connected to the ground after passing through a high-resistance fault setting module, the second path is connected to the ground after passing through a flashover fault setting switch, and the third path is connected to the ground after passing through a low-resistance fault setting switch; the second path of the cable test end is connected with a main terminal of a single-pole double-throw switch K2, the main terminal of the single-pole double-throw switch K2 includes two paths, the first path is connected to the ground after passing through a disconnection fault setting switch, and the second path is connected with the tail end of the cable. The system can simulate various cable faults, thereby reducing training time of employees, improving work efficiency, and the system has the characteristics of being simple in structure, being convenient to use and being low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of teaching or training devices in electric power systems, in particular to a cable fault simulation system. Background technique [0002] The power cable fault simulation system can simulate a variety of power cable faults, and it is a special equipment for teaching and training test personnel. It can cooperate with power cable fault test equipment to simulate on-site and demonstrate the detailed test process of various cable faults, which is convenient for testers to master cable fault test technology, shorten repair time, and reduce power failure losses. [0003] At present, there are some cable simulation devices in cable testing, but most of the simulation devices have a single function, and can only simulate simple fault types (short-circuit fault or disconnection fault) on a single device, and generally cannot for high-resistance faults. In the actual test process, most of the cable faults encountere...

Problems solved by technology

[0003] At present, there are already some cable simulation devices in cable testing, but most of the simulation devices have single functions, and can only simulate simple fault types (short-circuit fault or disconnection fault) on a single device, and generally cannot for high-resistance faults. In the actual test process, most of the cable faults encountered are high-resistance faults. In order to improve the test level of cable testers, in some electric industry departments or training centers, in order to simulate cable faults, a huge investment is required.
