Abstract

The invention discloses a voltage buffer power supply based on harmonic isolation. The characteristics lie in that the voltage buffer power supply is mainly composed of a control chip U2, a transformer T1, a transformer T2, a diode rectifier U1, an amplifier P, a triode VT1, a triode VT2, a triode VT3 and the like. The voltage buffer power supply has a great bandwidth, the dynamic response speed of the voltage buffer power supply can be improved, and the starting speed of an electrostatic dust collector is enabled to be higher. The voltage buffer power supply can improve the power factor, so that the efficiency of the voltage buffer power supply is improved. The voltage buffer power supply can also perform isolation on harmonic interference signals, so that a step-up transformer is avoidedfrom being polluted by harmonic waves, and the stability of the voltage buffer power supply is improved.

Description

technical field [0001] The invention relates to a power supply, in particular to a voltage buffering source based on harmonic isolation. Background technique [0002] Due to its high dust removal efficiency and low operating cost, electrostatic precipitator plays a very important role in reducing harmful dust discharged into the atmosphere. It is currently a widely used environmental protection equipment. It has been widely used in in people's lives. However, the power supply used by the existing electrostatic precipitator is easily damaged by impact, and in serious cases, the electrostatic precipitator will be damaged. Contents of the invention [0003] The purpose of the present invention is to solve the defect that the power supply used in the current electrostatic precipitator is easily damaged by impact, and provides a voltage buffering source based on harmonic isolation. [0004] The object of the present invention is realized by following technical scheme: a kind ...
