Abstract

The invention belongs to an intelligent three-phase electricity-saving protection controller which comprises a three-phase firewire, a zero line input terminal and an earth wire input terminal, wherein the three-phase firewire and the earth wire input terminal are connected with an input end of a transient surge suppression unit; an output end of the transient surge suppression unit and the zero line input terminal are connected with an input end of a voltage adjusting three-phase balancing unit, an output end of the voltage adjusting three-phase balancing unit is connected with an input end of a harmonic compensation unit, and an output end of the harmonic compensation unit is connected with a load. The intelligent three-phase electricity-saving protection controller integrates the advantages of a system type, a filtering compensation type, a voltage adjusting type and an electromagnetic type electricity-saving protection devices, so as to have good comprehensive treatment effect, reduce the electricity-saving cost, avoid installation and debugging for a plurality of electricity-saving devices in the installing process, save manpower, physical resources, financial resources and time consumption, and be suitable for a power system and electric equipment with multiple voltage classes.

Description

technical field [0001] The invention belongs to the field of power-saving protection equipment, in particular to an intelligent three-phase power-saving protection controller. Background technique [0002] There are problems of power waste and excess energy consumption in the existing power consumption system, which not only causes the waste of power resources, but even leads to the damage of power consumption equipment. The power waste in the power system mainly includes transients, surges, harmonics, etc. These power wastes will seriously reduce the power efficiency of the power system and cause serious impact damage to power equipment; excess energy consumption mainly reflects The power supply voltage in the power consumption system is higher than the rated voltage of the power consumption equipment. On the one hand, it causes a waste of power resources, and on the other hand, it has a negative impact on the power consumption equipment and reduces the service life of the ...
