The principle and control technology of low-voltage complete equipment?

low-voltage complete set of equipment ‌ is responsible for the control, protection, measurement, conversion and distribution of electric energy in the low-voltage power supply system. Because the low-voltage complete sets of equipment have penetrated into the production site, public places, residential and other places, it can be said that any place that uses electrical equipment should be equipped with the equipment. About 80% of China's electric energy is provided by low-voltage complete sets of equipment, so the development of low-voltage complete sets of equipment is rooted in the material industry, low-voltage electrical appliances, processing technology and equipment, from one side reflects a country's economic strength and science and technology, living standards ‌

principle
The working principle of low-voltage complete equipment mainly includes the following aspects:
main circuit ‌ : responsible for the transmission and distribution of electric energy, usually including the incoming line, outgoing line and bus and other parts.
auxiliary loop ‌ : used for the control and monitoring of equipment, including various sensors, controllers and actuators.
control technology ‌ : including fieldbus networking technology, PLC measurement and control programming technology and power monitoring technology, used to realize the remote monitoring and intelligent control of equipment ‌

Control technology
The control technology of low-voltage complete equipment mainly includes the following aspects:
fieldbus networking technology ‌ : the device is connected to the control center through the fieldbus to realize centralized monitoring and management of the device.
‌PLC measurement and control programming technology ‌ : The use of programmable logic controller (PLC) for automatic control and monitoring of equipment.
‌power monitoring technology ‌ : Through the power monitoring system to monitor and manage the electric energy usage of the equipment in real time, to ensure the normal operation of the equipment and energy efficiency optimization ‌

Application scenarios and maintenance
Low-voltage complete sets of equipment are widely used in various electrical systems, including industrial production, commercial buildings, residential and so on. Its maintenance includes regularly checking the parameters of the equipment, such as voltage, current, temperature, etc., to ensure that the equipment is in good working condition. In addition, you need to regularly clean the inside of the device to prevent dust accumulation from affecting the device performance ‌
