Abstract

The invention relates to a high-voltage power device for an electrostatic precipitator, in particular to a high-voltage power device capable of industrial frequency power supply. The high-voltage power device adopts the industrial frequency alternating current power supply to supply power to a boosting transformer, wherein the secondary side of the boosting transformer is provided with a rectification circuit which generates direct current high voltage after rectification and supplies the direct current high voltage to a dust collector body with a first dust chamber and a second dust chamber for collecting dust. The high-voltage power device is characterized in that the rectification circuit comprises a positive half-wave high-voltage silicon pile rectifier and a negative half-wave high-voltage silicon pile rectifier, wherein the positive half-wave high-voltage silicon pile rectifier is arranged between the secondary side of the boosting transformer and the first dust chamber and supplies power to the first dust chamber in the positive half wave; and the negative half-wave high-voltage silicon pile rectifier is arranged between the secondary side of the boosting transformer and the second dust chamber and supplies power to the second dust chamber in the negative half wave. The high-voltage power device solves the problem that the transformer with which the high-voltage power supply capable of industrial frequency power supply is equipped has large equipment volume and higher cost.

Description

technical field [0001] The invention relates to a high-voltage power supply device for industrial frequency power supply. Background technique [0002] Domestic electrostatic precipitator power supply equipment basically uses the high-voltage power supply technology of industrial frequency power supply, and a small amount of high-voltage power supply of high-frequency power supply. The rectifier circuit on the side adopts the circuit structure of full-wave bridge rectification. After the full-wave bridge rectification, DC high voltage is generated and supplied to the dust collector body for dust collection. For the high-voltage power supply of conventional industrial frequency power supply, although the technology is mature, reliable, and can meet the large-capacity requirements, such as 2A / 72KV, but for the same dust collector load requirements, the transformer equipment equipped with it is large in size, low in efficiency, and low in cost. higher. For the high-voltage po...

Problems solved by technology

For the high-voltage power supply with high-frequency power supply, it has the advantages of small size (about 1 / 3 less than the high-voltage power supply with industrial frequency power supply) and high efficiency, but the current technology is not mature enough, reliable, and has high requirements for the use environment , For example, the reliability is not high in places with high humidity along the coast. At the same time, the current domestic maximum capacity can only achieve 0.8A / 72KV, and the price is about 3 times that of high-voltage power supplies powered by industrial frequency.
