Description

Technical Field

[0001] The invention relates to the field of power supply boxes, in particular to a mobile power supply box. Background Art

[0002] The power supply box mainly provides operating power for vacuum circuit breakers and other high-voltage switches. The power supply box uses an input voltage of 220V or 380V, which is rectified by a thyristor voltage regulator to output DC. It has the characteristics of outputting DC voltage with multiple gears and large current or AC voltage, and can perform single-open and single-close operations. The DC power supply (DC power) has two electrodes, positive and negative. The positive electrode has a high potential and the negative electrode has a low potential. When the two electrodes are connected to the circuit, a constant potential difference can be maintained between the two ends of the circuit, thereby forming a current from the positive electrode to the negative electrode in the external circuit. "Forecast of the Development Prospects of China's Module Power Supply Industry and Investment Strategy Planning Analysis Report Prospects" points out that the difference in water level alone cannot maintain a steady water flow, but by using a water pump to continuously send water from a low place to a high place, a certain water level difference can be maintained to form a steady water flow.
