Terminals serve as secondary equipment protection

Wiring terminals play those roles in power applications. For the analysis of Xiaobian, the power system is a power production and consumption system consisting of power plants, transmission and distribution lines, power supply and distribution stations, and electricity. Its function is to convert natural primary energy into electricity by means of power generation, and then supply electricity to various users through transmission, transformation and distribution. In order to achieve this function, the power system also has corresponding information and control systems at various links and at different levels to measure, regulate, control, protect, communicate and dispatch the production process of electric energy to ensure users obtain safe and high-quality electric energy. The equipment division of the power system is divided into primary equipment and secondary equipment.
Primary equipment refers to electrical equipment that is directly used to produce, transform, transport, channel, distribute, and use electrical energy, and control loops (secondary equipment). The main components are: generator (motor), transformer, circuit breaker, disconnector, automatic switch, contactor, knife switch, bus, transmission line, power cable, reactor and so on.
An electrical main circuit that is connected to each other by a primary device to form a power generation, transmission, distribution, or direct use for production is called a primary circuit or a primary wiring system.
Primary device primary function:
1. Equipment for producing and converting electrical energy. For example, a generator that converts mechanical energy into electrical energy, a transformer that converts voltage, transmits electrical energy, a motor that converts electrical energy into mechanical energy, and the like.
2. Switch on and off the circuit's switching device. Such as high and low voltage circuit breakers, load switches, fuses, isolation switches, contactors, magnetic starters, etc.
3. Protect the electrical. Such as a reactor that limits the short-circuit current, and a lightning arrester that protects against overvoltage.
4. Current carrying conductor. Such as soft and hard conductors and cables that transmit electrical energy.
5. Grounding device.
“One time” mainly refers to the “main road” in power production, and “secondary” is mainly used to control “one time”. The device is modified "once", mainly to reflect that the voltage level of the device belonging to the main circuit or device is higher than the voltage level of the secondary device.
