Abstract

The invention discloses an electron beam bombarding furnace power supply. The power supply comprises a control cabinet A. The control cabinet A is successively connected to at least three power supplycabinets. Each power supply cabinet is individually connected to the control cabinet A. In the power supply cabinets which are successively connected, the power supply cabinet located at a head end and the power supply cabinet located at a tail end are connected to a voltage hall sensor B. The voltage hall sensor B is connected to a total voltage feedback DSP plate. The total voltage feedback DSPplate is connected to the control cabinet A. The invention also discloses a voltage-stabilization voltage balancing control method based on the electron beam bombarding furnace power supply. In the invention, problems that the reliability of a current high voltage power supply cabinet is low, cost is high and the voltage withstanding performance of a device is high are solved.

Description

technical field [0001] The invention belongs to the technical field of high-power high-voltage direct current power supply, and relates to a power supply for an electron beam bombardment furnace, and also relates to a voltage equalization control method for the above-mentioned power supply. Background technique [0002] In recent years, with the rapid development of economy and technology, the application of high-power DC power supply in the industrial field has become increasingly widespread, especially in the fields of refractory metal smelting, environmental dust removal in thermal power plants, and industrial waste gas treatment. Single-module DC power supplies or Multi-module decentralized DC power supply to achieve the purpose of high voltage output. However, the reliability of the current single-module high-voltage DC power supply is low, and the device has a high withstand voltage. Aluminum wires transmit signals, but copper-aluminum wires are susceptible to electro...
