High Voltage Complete Switchgear Cabinet
Product Title
Product Details
The GAOSUOJL-12 high-voltage metering cabinet (box) (hereinafter referred to as the "floor-standing metering box") is suitable for electric energy metering of high-voltage cable incoming users in AC three-phase 50Hz, rated voltage 10kV power systems. It can be installed on roadside lawns in parks, residential communities, and industrial and mining areas. The meter reading and breaker opening/closing operations can be conveniently performed by directly opening the door.
The floor-standing metering box mainly consists of a vacuum circuit breaker, cast-type combined instrument transformer, arrester, live display device, and intelligent control device. Its metering methods include three-phase three-wire and three-phase four-wire systems. A zero-sequence current transformer can be configured for grounding protection. The floor-standing metering box complies with technical standards such as GB/T 1984-2014 "High-voltage AC Circuit Breakers", DL/T 402-2016 "High-voltage AC Circuit Breakers", DL/T 403-2000 "Technical Conditions for Ordering 12kV~40.5kV High-voltage Vacuum Circuit Breakers", GB/T 17201-2007 "Combined Instrument Transformers", and DL/T 721-2013 "Remote Terminal Units for Distribution Automation Systems".
