GGD1\/GGD2\/GGD3 AC Low-Voltage Power Distribution Cabinet (Metering Cabinet)<\/h1>\n\n\n\n

1. Product Overview<\/h2>\n\n\n\n

GGD series metering cabinet is a fixed-type low-voltage metering special switchgear, applicable to AC 50\/60Hz, rated voltage 400V three-phase four-wire power distribution systems. It is matched with dry-type transformers, main incoming cabinets, bus coupler cabinets and feeder cabinets to realize accurate power measurement, electricity statistics and power parameter monitoring for the whole low-voltage power distribution system.<\/p>\n\n\n\n

This cabinet complies with IEC 60439-1 and GB 7251.1 international standards, adopting 8MF cold-bent steel frame with IP30 protection level. It is independently configured for power supply bureau metering acceptance, widely used in industrial plants, commercial buildings, residential districts, photovoltaic substations and various overseas power engineering projects. GGD1, GGD2 and GGD3 differ in short-circuit withstand capacity and busbar carrying current, which can meet the metering demands of small, medium and large power loads respectively.<\/p>\n\n\n\n

2. Standard Internal Configuration of Metering Cabinet<\/h2>\n\n\n\n
    \n
  1. Current Transformer (CT) High-precision measuring CT is installed on the main busbar, converting high primary current into standard secondary current signal for electric energy metering.<\/li>\n\n\n\n
  2. Multi-function Energy Meter Official certified bidirectional electric energy meter, capable of measuring active power, reactive power, voltage, current, power factor and cumulative electricity consumption.<\/li>\n\n\n\n
  3. Metering Terminal Block Special sealed secondary metering terminal row, convenient for wiring inspection and power bureau lead sealing to prevent illegal electricity stealing.<\/li>\n\n\n\n
  4. Isolating Switch Provide visible isolation fracture for safe maintenance of metering components and busbar.<\/li>\n\n\n\n
  5. Main Copper Busbar System Top-through L1\/L2\/L3 phase copper busbar, independent N neutral busbar and PE grounding busbar; all bus joints are tinned to reduce contact resistance.<\/li>\n\n\n\n
  6. Surge Protection Device (SPD) Suppress instantaneous overvoltage caused by lightning and grid switching to protect precision metering instruments.<\/li>\n\n\n\n
  7. Instrument Window & Lead Sealing Structure Transparent observation window on cabinet door to check meter data without opening the door; reserved lead sealing hole for power department anti-theft management.<\/li>\n<\/ol>\n\n\n\n

    4. Working Principle<\/h2>\n\n\n\n

    The 400V low-voltage power transmitted from the main incoming cabinet enters the metering cabinet through the top copper busbar. The three-phase current passes through the high-precision CT, and the CT converts large load current into small secondary current signal and transmits it to the multi-function energy meter.<\/p>\n\n\n\n

      \n
    • Real-time metering: The meter synchronously collects voltage and current signals to calculate active and reactive power consumption, realizing accurate electricity measurement for settlement.<\/li>\n\n\n\n
    • Isolation maintenance: When overhauling metering equipment, the isolating switch can be opened to form an obvious breaking point to ensure maintenance safety.<\/li>\n\n\n\n
    • Anti-theft power design: The closed metering terminal block and cabinet door lead sealing structure avoid unauthorized wiring modification, which meets the unified acceptance standard of power grid departments at home and abroad.<\/li>\n\n\n\n
    • Overvoltage protection: SPD absorbs lightning surge to avoid damage to high-precision metering instruments.<\/li>\n<\/ul>\n\n\n\n
