Where are power facility accessories used

       Power facility accessories are an important component of the normal operation, maintenance, and expansion of the power system, widely used in various aspects such as power generation, transmission, transformation, distribution, and consumption. The following are its main application scenarios and specific explanations:

1、 Power generation process

       The power generation process is the starting point of the power system, requiring various accessories to ensure the stable operation of the generator set and auxiliary equipment.

       Thermal power generation: Boiler pipeline connectors (such as flanges and elbows), turbine seals, generator wiring terminals, cooling system valves, etc., used for transmitting media, sealing equipment, connecting circuits, and controlling the flow of cooling water.

       Hydroelectric power generation: The bearings and blade fasteners of the water turbine, the electric brushes of the generator, and the cable protection pipes between the dam and the generator set ensure lubrication of mechanical components, stable output of electrical energy, and cable safety.

       New energy generation (photovoltaic, wind power): bracket connectors (bolts, buckles) for photovoltaic panels, heat sinks for inverters, flanges for wind power towers, fixing bolts for wind turbine blades, etc., used to fix equipment, dissipate heat, and connect tower sections.

2、 Transmission process

       The transmission link is responsible for long-distance transmission of the electricity generated by the power plant, and the accessories need to adapt to harsh environments such as high voltage and outdoor conditions.

       Overhead transmission lines: Insulators (ceramic, composite insulators) are used to isolate conductors from towers and prevent leakage; Wire connectors (crimping tubes, tension clamps) are used to connect wires and withstand tension; The anchor bolts and cross arm fasteners of the tower ensure the stability of the tower structure.

       Cable transmission lines: Cable intermediate joints and terminal heads are used for sealing and insulating cable connections; Cable protection pipes (MPP pipes, fiberglass pipes) protect underground cables from external damage; Cable supports are used to support the laying of cables in tunnels or cable trays.

3、 Substation process

      Substation is the core of power conversion, which converts high voltage electricity into medium and low voltage through transformers, and its accessories need to meet high-precision and high insulation requirements.

      Transformer related: The tap changer (regulating output voltage), cooling fan, oil tank seal (preventing oil leakage), bushing (insulating and leading out wires), etc. of the transformer ensure voltage regulation, heat dissipation, and insulation safety.

      Switchgear: operating mechanism of circuit breaker (driving switch on/off), contacts of isolation switch (realizing circuit on/off), door lock and observation window of switchgear, used to control circuit on/off and ensure the safety of operators.

      Reactive power compensation equipment: Fuses for capacitor banks, wiring terminals for discharge coils, used to protect capacitors and achieve discharge function, maintaining stable power factor of the power grid.

4、 Distribution process

      The distribution process distributes electricity to users, and accessories need to adapt to the needs of multiple scenarios and loads.

      Distribution transformer: Similar to substation transformers, but with a smaller capacity, its terminals, temperature controllers, and other accessories are used to connect user lines and monitor equipment temperature.

      Distribution box/cabinet: internal air switches, leakage protectors, busbars, and terminal blocks used for distributing electrical energy, protecting circuits, and connecting user lines.

      Outdoor power distribution facilities: porcelain bottles (insulated wires) on utility poles, drop out fuses (protective branch lines), locks and terminal heads for metering boxes, used for power distribution and metering in rural or outdoor areas.

5、 Electricity consumption process

      The electricity consumption process is directly aimed at industrial, commercial, and residential users, and accessories need to pay attention to safety and convenience.

      Industrial users: Bus duct connectors in factory workshops, junction boxes for motors, fixing bolts for explosion-proof lighting fixtures, suitable for power transmission and explosion-proof environmental requirements of high-power equipment.

      Commercial and civil buildings: Circuit breakers in floor distribution boxes, wiring terminals for socket panels, ballast brackets for lighting fixtures, used for indoor power distribution, connection of electrical equipment, and stable operation of lighting systems.

       Public facilities: Lamp pole flanges for streetlights, cable connectors for traffic signal lights, charging interface accessories for charging stations, ensuring power supply and equipment connection in public areas.

6、 Power operation and repair

      In the daily maintenance and emergency repair of power facilities, accessories are equally indispensable.

      Operation and maintenance tool accessories: connecting wires for insulated gloves, probes for voltage testers, and wire clamps for grounding wires, used to ensure the safe operation of operation and maintenance personnel.

      Repair replacement parts: quick connectors for temporary cables, door locks for emergency switchgear, spare parts for damaged insulators, used for quick restoration of power supply.
