YB Overview
Intelligent box substation of series YB, adopts environments protection and new material, new technology and
advanced components as wel as high-low voltage automation technology, and among them, the high voltage side(12KV)
can meet the demanding of power department for power distribution automation, and the lower 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 auotmatic location ,fault clearance, load shifting and network
recofiguration at the fault section,
so that the recovery of power transmission is guranteed in one minute.This series of intellient box substation is one optimized combination
of complete intelligent power supply and distribution integrated device consisting of high voltage unit,power transformer, low voltage unit,
metering unit and intelligent system etc. It has the characteristics of multi-functions, wide application.
Substation series
Safe and reliable operation, beautiful out lines, as well as convenient installation, little land occupation, little maintenance, low cost,
quick effect and long service lift.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.
