The primary and secondary ring network cabinet set is mainly composed of primary loop equipment, high precision voltage and current zero sequence mutual inductor, secondary power distribution terminal equipment, the primary loop of the primary and secondary ring network cabinet set transmits, transforms and distributes electric energy, the primary loop is to protect, measure, control and calculate the primary loop equipment, the secondary loop adopts standard navigation interface or rectangular connector for easy interchangeability. The primary and secondary loops are customized, and the terminals and navigation plugs are defined to increase the interchangeability and versatility of the equipment.
The primary and secondary ring network cabinet set functions with single-phase ground fault, short circuit fault detection and excision; realized high-precision three - remote function, achieved telemetry accuracy is phase voltage 0.5 level, phase current 0.5s level; functions with preventing inrush current and load fluctuation;
According to the special inspection requirements of the State Grid Corporation for the integration of the primary and secondary ring network cabinet set, we corporate with Shijiazhuang Colin, DEFEILE Technology and other distribution terminal manufacturers, completed SF6, solid insulation and environmental gas the primary and secondary fusion test and have been obtained qualified reports.
