2015
The invention discloses a double-power-supply control box with an anti-misoperation function. The control box comprises a box body, wherein a first input/output power supply wiring terminal, a second input/output power supply wiring terminal, a quadrupolar double-throw power supply switch, a third input/output power supply wiring terminal and a leakage protection circuit are arranged in the box body, wherein a standby power supply supplies power through the second input/output power supply wiring terminal and is electrically connected with an input end of the quadrupolar double-throw power supply switch; an outlet end of the quadrupolar double-throw power supply switch is electrically connected with the third input/output power supply wiring terminal through the leakage protection circuit and connected with power supply equipment through the third input/output power supply wiring terminal. Compared with the prior art, the double-power-supply control box with the anti-misoperation function has the advantages as follows: the control box is simple in structure, high in reliability and high in site durability, has a load switch-out protection function and can prevent potential risks caused by misoperation.
