Embodiment Construction

[0028] The main circuit and control circuit parts of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation is given, but the protection scope of the present invention is not limited to the following embodiments.

[0029] 1. Main circuit

[0030] The main circuit part is mainly composed of voltage regulators AX, BX, CX, transformers C1, C2, C3, and switches KM1~KM5. The switches KM1~KM5 here can be relays or contactors, such as figure 1 shown. Among them, KM1~KM3 are switches for energy saving and bypass switching in the main circuit, and KM4 is the output side of the voltage regulator, that is, the input control switch on the primary side of the transformer. When the voltage regulator fails, the switch KM4 is energized, and the normally open contact is closed, so that the transformer is disconnected fro...

Abstract

The invention discloses a seamless switching circuit for a three-phase full-automatic alternating-current electricity-saving device. The circuit comprises a main circuit and a control circuit; functions of the three-phase full-automatic alternating-current electricity-saving device, such as energy saving, voltage stabilizing and high power supply quality, are realized by adopting technological means, such as seamless switching, three-phase balance, intelligent voltage adjustment and automatic capacity adjustment; the main circuit is mainly composed of a voltage adjustor, a transformer and a switch; seamless switching of an electricity-saving device bypass and an energy-saving state is realized by reasonably controlling closing and disconnection sequences of the switch in the main circuit; the control circuit is composed of a switching circuit, a clock signal generation circuit and a switch driving circuit; a drive signal is output to drive the switch of the control circuit; and ordered closing and disconnection of the switch of the main circuit are controlled through the switch of the control circuit. The seamless switching circuit disclosed by the invention can be automatically switched to commercial power supply under conditions that load electricity consumption is influenced or the device is further destroyed due to the fact that the electricity-saving device is failed; therefore, energy-saving and non-energy-saving automatic seamless switching can be realized; and thus, the power supply safety and stability are ensured.

Description

technical field [0001] The invention relates to the technical field of bypass conversion of power-saving devices, in particular to a seamless switching circuit of a three-phase fully automatic AC power-saving device. Background technique [0002] The three-phase fully automatic AC power-saving device realizes functions such as energy saving, voltage stabilization, power supply quality optimization, and equipment service life extension through technologies such as intelligent voltage regulation, automatic capacity regulation, three-phase balance, and energy efficiency optimization. Business operating costs. However, when the power-saving device operates abnormally and will cause damage to itself or the load, in order to ensure the safety of power consumption and the normal and stable operation of power-consuming equipment, it is necessary to seamlessly switch the power-saving mode to the bypass mains power supply mode in time. [0003] The present invention is invented to so...
