Abstract

The invention discloses a voltage buffer power supply based on surge protection. The characteristics lie in that the voltage buffer power supply is mainly composed of a control chip U2, a transformerT1, a transformer T2, a diode rectifier U1, an amplifier P, a triode VT1, a triode VT2, a triode VT3, a capacitor C3 and the like, wherein a positive electrode of the capacitor C3 is connected with anegative electrode output end of the diode rectifier U1, and a negative electrode of the capacitor C3 is connected with a positive electrode output end of the diode rectifier U1. 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.

Description

technical field [0001] The invention relates to a power supply, in particular to a voltage buffer power supply based on surge protection. 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 due to impact, and to provide a voltage buffer power supply based on surge protection. [0004] The purpose of the present invention is achieved through the following technic...
