YB Intelligent prefabricated substation
Overview
Intelligent box substation of series YB, the newest product developed independently by ZHIDUOXIN Company integrates the advantagesof American box substation, European box substation and home box substation which adopts environment protection and new material, new technology and advanced components as well as high-low voltage automation technology, and among them, the high voltage side (12KV) can meet the demand of power department for power distribution automation, and the low voltage side (0.4KV) can meet the demand of intelligent community property management, and the upper monitor which is located in the central station or the property management department can be used for four-remote (remote measurement, remote communication remote adjustment, remote control) system management. When several intelligent box substations connect into “hand-in-hand” ring network and supply power, they, combined with autonomous software, can accomplish the functions of automatic location, fault clearance, load shifting and network reconfiguration at the fault section, so that the recovery of power transmission is guaranteed in one minute. This series of intelligent box substation is one optimized combination of complete intelligent power supply and distribution integrated device consisting ofhigh voltage unit, power transformer, low voltage unit, metering unit and intelligent system etc. It has the characteristics of multi-functions, wide application, safe and reliable operation, beautiful out line,as well as convenient installation, little land occupation, little maintenance, low cost, quick effect and long service life. It can be used as power transformation and distribution equipment in the following departments and places, such as urban architecture, residential areas, municipal facilities, factories, mines, roads, wharves and oil fields, as well as construction in need of temporary power supply.
