Operation principle:
Press the SB2 that releases the button, SB2 is closed, and KA coil obtains electric, the closed self-locking of its normally opened contact KA-1, even if unclamp SB2, KA coil is still in obtaining electricity condition; Simultaneously, normally opened contact KA-2 is closed, starting 220V AC power is load supplying, 220V AC power is exported DC power supply after transformer pressure-reducing, single phase bridge type rectifier circu UR rectification, described DC power supply is through D2 step-down, shaping, after C1, C2 filtering, through 7805 voltage stabilizings outputs, then after C3 filtering for load provides galvanic current source.
KA coil obtains electric, and its normally-closed contact KA-3 disconnects, and storage battery is cut, is not load supplying.Realization exchanges, direct current is selected an output.
When alternating current normal power supply, fuse FU fault-free, the pressure drop at fuse FU two ends is very little, and electric current flows through from fuse FU, and VL1 does not work; When fuse FU fuses, alternating current, after D1 rectification, flows through VL1, R1; VL1 is bright, and indicating fuse FU breaks down.
When alternating current power-off or fuse FU break down, KA coil losing electricity, its normally-closed contact KA-3 recovers closure state, storage battery by the switching without the time difference most load working power is provided, indicator light VL3 is bright simultaneously.
Because of KA coil losing electricity, its normally opened contact KA-1 and KA-2 recover off-state.
If 220V AC power is recovered incoming call, but can not be switched to the operating state into load supplying, because of now, SB2 and KA-1 in parallel disconnect, and KA coil must not be electric, and therefore, the former limit of transformer T is open-circuit condition.
When through after a period of time, it is believed that fault keeped in repair, during stable alternating-current power, manually press SB2, switch to AC-powered mode.
