Title:
CIRCUIT USING ALTERNATING CURRENT PANEL SWITCH TO IMPLEMENT DIRECT CURRENT SHUTDOWN
Document Type and Number:
WIPO Patent Application WO/2020/258690
Kind Code:
A1
Abstract:
Disclosed in the present invention is a circuit using an alternating current panel switch to implement direct current shutdown, comprising a switch power source, a direct current contactor, a panel switch, and a load, the direct current contactor comprising a contactor coil and a corresponding normally-open contactor switch; the switch power source comprises a direct current power source, a positive electrode terminal connected to a positive electrode of the direct current power source, a negative electrode terminal connected to a negative electrode of the direct current power source, a live wire terminal connected to a positive electrode of an external alternating current power source, and a neutral wire terminal connected to a negative electrode of the external alternating current power source; the contactor coil and the panel switch are connected in series to form a first branch, one end of the first branch being connected to the positive electrode terminal, and the other end of the first branch being connected to the negative electrode terminal; and the normally-open contactor switch and the load are connected in series to form a second branch, one end of the second branch being connected to the positive electrode of the external alternating current power source, and the other end of the second branch being connected to the negative electrode of the external alternating current power source. The present invention controls the closing and disconnection of the contactor switch in the alternating current circuit by means of the panel switch in the direct current circuit, and thereby implements control of the load.
