Description
Technical Field
The invention belongs to the technical field of partial discharge detection, and particularly relates to a partial discharge detection system based on multiple sensors.
Background
The switch cabinet is used as an internal main device of a power distribution system, and the feasibility of the whole system is influenced by the internal organization structure and the working condition of the switch cabinet. Once a switch cabinet is in fault or deviation, irreversible results can be brought, the most direct influence is that lines and devices protected by an electrical system are damaged, so that large-scale electric quantity is lost, and indirect influence can cause local area power failure, so that basic power supply cannot be guaranteed. The switch cabinet in the power distribution system has insulation property, however, the insulation function is seriously affected by deterioration due to the influence of high temperature, high voltage, high-wave-rate vibration and weather moisture for a long time. Most of the causes of switchgear failure are due to the breakdown of its insulating properties, while local transmission line leakage is usually the main cause of the breakdown of the switchgear insulation. Therefore, effective identification of the partial discharge condition of the switch cabinet is one of effective measures for maintaining the normal operation of the switch cabinet.
