China NY6-12 Integrated Ring Main Switchgear Suppliers - Advanced Power Distribution Factory Equipment
Overview
With the continuous development and progress of society, my country's urban power grid has undergone tremendous changes. Most cities have formed or are forming power load-intensive areas. The previous power supply from the substation 12/24kV line (or branch line) to the direct user end can no longer meet the requirements of urban development, so a new power supply method through switching has emerged.
NY6-12 (V, C, PT) /630-25, BD-163 integrated primary and secondary ring network switchgear and station terminals are intelligent complete sets of equipment launched in response to the requirements of the State Grid Standard "Technical Standards for Primary and Secondary Equipment of Power Distribution". They are complete sets of equipment that integrate electromagnetic voltage and current transformers, electric energy metering modules, high-speed fault transient waveforms and other advanced technologies.
It consists of a ring inlet and outlet unit, a feeder unit, a busbar equipment (PT) unit, a centralized DTU and connecting cables. It can collect active power, reactive power, power factor, frequency, zero-sequence current and zero-sequence voltage, and has line loss metering, electric energy metering, line voltage identification, voltage over-limit, load over-limit and other alarm sending, short-circuit fault detection and processing, single-phase grounding fault detection and processing functions, and supports the sending of short-circuit/grounding fault events to meet the needs of distribution network automation.
Key Features
Based on the traditional DTU function, the metering-level distribution line loss collection function is added, the judgment and positioning function of small current grounding fault is optimized, the sampling frequency is increased, and the fault recording is more accurate. The waveform is closer to the real waveform.
