Abstract

The invention discloses a rectification power supply control device for a combined arc heater. The method includes a control module, a rectification module and a heating module. The control module includes a power supply host computer, a heating host computer and a PLC master station. The rectification module includes a rectification power supply PLC slave station, a rectification power supply thyristor pulse controller, a rectification power supply relay unit and a rectification power supply. The heating module is a combined arc heater, including two high-power heaters. The invention realizes the remote operation, synchronous control and synchronous output of two rectifier power supplies to meet the simultaneous power supply conditions for high-power combined DC heaters. Uploading fault information is easy to find and analyze. This method is extended to more control fields and can realize the operation of DC heaters with higher power.

Description

technical field [0001] The invention relates to the technical field of industrial automation control, in particular to a rectified power supply control device for a combined arc heater. Background technique [0002] With the continuous development of my country's space technology, research on spacecraft materials has become one of the key technologies. During the process of the spacecraft passing through the atmosphere, the high-speed friction will make its surface materials withstand the external environment such as high temperature and high pressure. In order to prevent aerodynamic heating from damaging or even destroying the spacecraft and causing serious accidents, the heat-resistant material of the heat-resistant system needs to be tested on the ground to evaluate its heat-resistant performance. It uses the high temperature of the arc to heat the gas, which can provide screening, ablation and ablation shape change experiments for spacecraft heat-resistant materials, th...
