The invention discloses an auto-putting-in and auto-recovering power supply system. The auto-putting-in and auto-recovering power supply system comprises a main branch with the electricity supplied by electric supply and an auxiliary branch with the electricity supplied by an engine. The wire outlet side of the main branch and the wire outlet side of the auxiliary branch are connected with the same lower end load, an A-phase wire, a B-phase wire and a C-phase wire of the main branch are provided with a first breaker, and an A-phase wire, a B-phase wire and a C-phase wire of the auxiliary branch are provided with a second breaker. The first breaker is provided with a first closing loop controlling the closing of the first breaker and a first opening loop controlling the opening of the first breaker. The second breaker is provided with a second closing loop controlling the closing of the second breaker and a second opening loop controlling the opening of the second breaker. The first closing loop and the second closing loop are electrically interlocked so that the second opening loop can be started when the first closing loop works, the first opening loop and the second opening loop are electrically interlocked so that the second closing loop can be started when the first opening loop works, and the auto-putting-in and auto-recovering purposes of the two paths of power supply of the electric supply and the electricity generating are achieved.
Description
technical field [0001] The invention relates to a power supply system, in particular to a self-switching and self-resetting power supply system. Background technique [0002] The lower-end load of the 380V system powered by mains and power generation is generally an important load, which has high requirements on the reliability of power supply, and requires the system to provide uninterrupted power supply. This type of system is generally equipped with two incoming circuit breakers, one is the mains incoming circuit breaker, whose incoming power is taken from the mains; the other is the generation incoming circuit breaker, whose incoming power is taken from the generator. Under normal conditions, mains power is used for power supply. Once the mains power fails, the system is required to immediately switch to the emergency mode, that is, the generator power supply mode. Since the power distribution room is often unattended, in order to ensure uninterrupted power supply to the...
