Abstract

The invention discloses an electric control box for switching power supply of main and auxiliary power sources, comprising: a first power supply circuit, a second power supply circuit, a first control loop, a second control loop and a switching module, the first control loop, the second The control circuit and the switching module are used to switch the first power supply circuit to the second power supply circuit, or to switch the second power supply circuit to the first power supply circuit; the switching module includes a three-position switching knob, and the three-position switching knob switches to the first power supply circuit position, the first power supply circuit is the main power supply circuit, and the second power supply circuit is the auxiliary power supply circuit. After the first power supply circuit fails and the power is cut off, the second power supply circuit is controlled to supply power; when the three-position switching knob is switched to the third position, the second power supply circuit The second power supply circuit is the main power supply circuit, the first power supply circuit is the auxiliary power supply circuit, and the first power supply circuit is controlled to supply power after the second power supply circuit fails and is powered off. The electrical control box disclosed by the invention is used for switching main and auxiliary power supply circuits, and has low cost and reliability.

Description

technical field [0001] The invention relates to an electrical control box used for switching power supply between main and auxiliary power sources. Background technique [0002] The existing main and auxiliary power switching devices are expensive, bulky, and inconvenient to install, and there is room for improvement.
