Abstract

The invention provides an electric effect enhancing device, which is applied to a power grid. The electric effect enhancing device comprises a common-mode restraining unit, a difference-mode restraining unit and a harmonic absorbing unit, wherein the common-mode restraining unit is used for restraining a common-mode interference signal in a power grid input circuit; the difference-mode restrainingunit is used for performing difference-mode interference signal restraining on a signal undergoing a common-mode interference signal restraining implemented by the common-mode restraining unit; and the harmonic absorbing unit is used for performing harmonic absorption on a signal undergoing difference-mode interference signal restraining. Through adoption of the technical scheme, the aim of increasing the electric effect is realized; transient voltage can be absorbed at a high speed; a certain lightning protection effect is achieved; and the requirement on power energy control of an enterprise can be met.

Description

technical field [0001] The invention mainly relates to the field of electric power technology, and in particular to an electric efficiency enhancing device. Background technique [0002] Electric energy is the most important form of energy supply for the national economy, and there is a huge energy-saving potential in terminal electricity consumption. Thousands of power consumption units in the terminal grid are constantly changing, interfering with each other, and interacting with each other, forming a complex power energy system. [0003] When the power supply is supplying power to the load equipment, there will be transient overvoltages that enter the line, causing the voltage in the line to exceed the voltage range that the load equipment can withstand, thus causing damage to the load equipment. [0004] Therefore, it is an urgent technical problem to provide an electric efficiency enhancing device. Contents of the invention [0005] The main purpose of the present in...
