Abstract
The utility model discloses an alternating current-direct current comprehensive load box, which is composed of a direct-current contact interlocking circuit, a single-phase alternating-current contact interlocking circuit, a three-phase alternating-current contact interlocking circuit and a load regulating circuit, wherein the load regulating circuit is switched among three output loads by the three contact interlocking circuits, and the sizes of loads on the load regulating circuit can be regulated. When one contact interlocking circuit is in working, other two contact interlocking circuits are latched up. The load output ends of the direct-current contact interlocking circuit, the single-phase alternating-current contact interlocking circuit and the three-phase alternating-current contact interlocking circuit are respectively provided with a circuit breaker, and three circuit breakers and the regulating switch of the load regulating circuit are arranged on a load box panel. The alternating current-direct current comprehensive load box has the advantages that the load box has three load output modes and convenient operation; when one circuit is in load output, other two circuits are not accessed by the contacts of contactors, so the safety of equipment operation is increased.
