Abstract

The invention discloses an intelligent phase and electricity output and exchange device, and a control method thereof, which relate to the technical field of the phase and electricity selection of a three-phase and four-wire power supply outlet. The load interface power supply phase of the three-phase and four-wire power supply can be easy to change, and the automatic exchange of the load interface power supply phase can be realized based on the unbalance of the three-phase upper power factor. The intelligent phase and electricity output and exchange device comprises A phase, B phase, C phase,a zero line N, three load interfaces, a controller, and a plurality of nodes. The intelligent phase and electricity output and exchange device also comprises a three-phase power factor monitoring device, an interface power factor monitoring device, two phase voltage sampling circuits, two single-phase inversion power supply, two filters, two isolation transformers, two load interface voltage sampling circuits and a plurality of switches, which are respectively connected to the controller. The change of input phase and electricity among each load interface can be controlled through the controller.

Description

technical field [0001] The invention relates to the technical field of phase power selection of a three-phase four-wire power output port, in particular to an intelligent phase power output switching device and a control method thereof. Background technique [0002] With the development of economy and society, there are more and more types of electrical equipment. Since the current power supply system is generally a three-phase power supply system, in the three-phase power supply system, if the power factor on the three phases is relatively asymmetric, the unbalanced operation of the power grid will occur, and the power grid will jitter. [0003] When the power grid is running in an unbalanced state, the transformer in the power grid is in an asymmetric running state. A transformer in an asymmetric running state will cause the zero-sequence current of the transformer to be too large, and the excessive zero-sequence current will cause the local parts of the transformer to ove...
