Product Description

  • 产品描述
  • The p primary and secondary fusion ring cage is an intelligent equipment set designed to meet the State Grid Corporation of China's latest Technical Standard for Primary and Secondary Power Distribution Equipment.It incorporates advanced technologies including electromagnetic voltage and current transformers,energy metering modules,and high-speed fault transientfitering.Comprising loop inlet and outlet units,feder units,and busbar equipment(PT)units,along with centralized DTUs and connecting cables,this system can collect data on active and reactive power,power factor. frequency,zero-sequence curent,and voltage.It ofers line loss and energy metering capabiities,along with line voltage identification,alerts for voltage and load imit violations,short-circuit fault detection and resolution,and single-phase grounding fault detection and handling,facilitating the transmission of short circuit/grounding fault events to fulfill the needs of distribution network automation.

    Main Features

    Adopt voltage-time based electromagnetic mechanisms or conventional spring operating mechanisms.

    1.Feature conventional protection,voltage and current types,and distributed intelligent FA functions.

    2."Centralized and decentralized control terminal is intuitive and easy to use.

    3.Employ CVT electronic voltage sensing technology.

    4.The isolation knife is integrated with the vacuum arc extinguishing chamber.

    5.A supercapacitor backup power supply that is maintenance-free throughout its entire lifecycle.

    6.Circuit breakers and load switches can be flexibly and conveniently grouped in any cabinet.
