Cable Fault Simulation System

Abstract

The invention discloses a cable fault simulation system, which relates to the technical field of devices used for teaching or training in electric power systems. Including the cable, the test end of the cable is divided into two circuits, the first circuit of the cable test terminal is connected to the first main terminal of the single-pole three-throw switch K1, and the main terminal of the single-pole three-throw switch K1 is divided into three circuits, of which the first circuit Grounded after the high-resistance fault setting component, the second road is grounded after the flashover fault setting switch, and the third road is grounded after the low-impedance fault setting switch; the second road of the cable test end is connected to the main terminal of the single-pole double-throw switch K2 , The main terminal of the single-pole double-throw switch K2 is divided into two circuits, the first circuit is grounded after the disconnection fault setting switch, and the second circuit is connected to the end of the cable. The system can simulate various cable faults, reduces the training time of practitioners, and improves work efficiency. In addition, the system has the characteristics of simple structure, convenient use and low 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...

[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.
