Anhui Mingge Electric Co., Ltd.

Low-voltage switchgear is a key device in power systems used for distributing, controlling, and protecting low-voltage circuits. Its core components include the following:
1. Low-voltage switchgear and distribution boxes: Used to control and protect low-voltage circuits, providing disconnection, isolation, protection, and measurement functions, distributing electrical energy to electrical equipment or the power grid. Common types include fixed and drawer-type switchgear, internally equipped with circuit breakers, disconnect switches, fuses, and other components.

2. Electricity metering equipment: Bidirectional electricity meters are used to record the electrical energy supplied to the grid by the photovoltaic system and the electricity consumed from the grid, supporting accurate metering of bidirectional power flow.
3. Grid-connected inverter: Converts the DC power generated by the photovoltaic modules into AC power, and has functions such as high-power point tracking, anti-islanding protection, and voltage regulation to ensure that the electrical energy meets grid requirements.
4. Cables and connecting components:
DC cables: Connect the photovoltaic modules and the inverter; the wire diameter must be selected according to the current. 5. AC Cable: Connects the inverter to the power distribution system, typically using a three-wire system (L/N/PE).
6. Protection and Grounding System: Includes overcurrent protection, leakage current protection, lightning protection devices, and a grounding system to ensure equipment safety and personal safety.
7. Auxiliary Equipment: Such as ventilation and heat dissipation devices, fire-fighting equipment (fire extinguishers), monitoring systems, etc., to ensure stable equipment operation.
