Embodiment Construction

[0033] Through the use of this system, trainees can greatly improve the training effect of partial discharge live detection in an absolutely safe learning environment, improve and assess the technical and skill level of trainees engaged in live detection operations, and effectively improve the overall operation and maintenance personnel of power supply and consumption Skill levels.

[0034] The system has:

[0035] 1. There are real high-voltage equipment but the equipment is not loaded with high voltage, real scene scene and real operation process;

[0036] 2. Since the simulated partial discharge signal has no audible noise, the signal maintains a high degree of stability during the training process and is basically not affected by environmental factors, which is a standardized assessment link in the training process;

[0037] 3. Only weak signals far below the safe voltage are loaded on the training equipment, and no high voltage is applied to the training equipment, so th...

Abstract

The invention relates to a partial discharge detection simulation training system, which comprises multiple groups of distribution network equipment, a simulation control unit and simulation terminals, and is characterized in that multiple groups of simulation terminals are distributed and installed in each group of distribution equipment; the simulation control unit sends control signals and on-off signals with specified intensity to one or more groups of simulation terminals of the distribution equipment; and the simulation terminals realize startup or shutdown according to the on-off signals sent by the simulation main control unit, and output high voltage loading free partial discharge signals with predetermined amplitude according to the control signals sent by the simulation main control unit. The partial discharge detection simulation training system overcomes problems and defects of lack of real scenes, lack of assessment links, existence of potential safety hazards and inability of performing united training for various partial discharge states of existing partial discharge training equipment.

Description

technical field [0001] The invention relates to the field of state maintenance and on-line monitoring of power equipment, in particular to a simulation training system for partial discharge electrification detection of distribution network equipment without high voltage loading. Background technique [0002] Power distribution equipment such as high-voltage switchgear and ring main unit are the largest power assets of State Grid Corporation of China. The implementation of condition-based maintenance for high-voltage switchgear has become an important challenge for grid companies to improve operation and maintenance levels and power supply reliability. During the Beijing Olympic Games, Shanghai World Expo and Guangzhou Asian Games, transient ground voltage and ultrasonic partial discharge live detection technology were widely used in the political power supply tasks of the above-mentioned international activities, and helped power supply companies discover and deal with many p...
