People are concurrently developing related power electronic devices and switching frequency conversion technology in the switching power supply domain, with both promoting each other to drive the annual growth rate of switching power supplies to exceed double-digit percentages, moving towards lightweight, compact, thin, low-noise, high-reliability, and anti-interference directions. Switching power supplies can be divided into two major categories: AC/DC and DC/DC. To quantitatively understand the operating conditions of electrical equipment, various measuring instruments are required, which measure various parameters of the circuit, such as voltage, current, frequency, and power levels.

The sequence of operations is shown from left to right or top to bottom in the diagram, with an effort to minimize lines and avoid intersections. 7. The connection points of crossover wires with direct electrical contact (i.e., the crossover points of the wires) should be indicated by black dots. For crossover wires without direct electrical contact, no black dots should be drawn at the crossover points. 8. Divide the diagram into several sections above the schematic, and label the purpose and function of the circuit in each section; below the relay and contactor coils, list the contact table to explain the relationship between the coils and contacts.

The basic circuit of the commonly used control lines in the system composition consists of the following parts: 1. Power supply circuit: The power supply sources for the power supply circuit include AC380V and 220V, etc.; 2. Protection circuit: The working power sources for the protection (auxiliary) circuit include single-phase 220V, 36V, or DC 220V, 24V, etc., which provide various protections such as short-circuit, overloading, and voltage drop for electrical equipment and circuits, composed of components like fuses, thermal relays, voltage drop coils, rectifier modules, and voltage stabilizer modules; 3. Signal circuit: A circuit that can promptly reflect or display information about the normal and abnormal operating status of equipment and circuits, such as signal lights of different colors and audio equipment with different sounds; 4. Automatic and manual circuits: To improve work efficiency, electrical equipment generally has an automatic section. However, during installation, debugging, and emergency accident handling, manual sections are also needed in the control circuit, which can be achieved through combination switches or changeover switches to switch between automatic and manual modes.

Dense insulated busbar trunking (CMC). Its moisture-proof and heat dissipation effects are poor. In terms of moisture-proof, the busbars are prone to dampness and seepage during construction, leading to a decrease in inter-phase insulation resistance. The heat dissipation of the busbars mainly relies on the housing, as the compact arrangement of the wires results in slow heat dissipation of phases L2 and L3, causing an elevated temperature rise in the busbar trunking. Dense insulated busbar trunking, limited by the housing material, can only produce horizontal sections not exceeding 3 meters. Due to the small air gap between busbars, when passing through large currents, a strong electromagnetic force is generated, causing the magnetic oscillation frequency to form an overlapping state, resulting in excessive noise. shxjhs88shhc99
