The invention discloses a high-voltage discharge test control system with a secondary control protection function and particularly relates to the field of high-voltage discharge tests. The system comprises a control module, wherein a display module is arranged at the output end of the control module, and an overvoltage protection module, a short-circuit protection module, an overcurrent protectionmodule, a breakdown flashover protection module, a startup zero protection module and a frequency converter overload protection module are arranged at the connection end of the control module. According to the system, through the overvoltage protection module, the short-circuit protection module, the overcurrent protection module, the breakdown flashover protection module, the startup zero protection module, the frequency converter overload protection module, a power-down protection module, a mistuning protection module, a bridge arm voltage protection module, an effect protection module, a cooling fan linkage protection module, an output voltage limiting function protection module, a phase absence protection module, a control box and an optical fiber fault protection module, a device, atest piece and a worker are effectively protected, and the safety is higher compared with the prior art.
Description
technical field [0001] The invention relates to the technical field of high-voltage discharge tests, and more specifically, the invention relates to a high-voltage discharge test control system with secondary control and protection functions. Background technique [0002] Partial discharge detection is an important measure to reflect the insulation status of equipment. Transformer partial discharge tests have been carried out extensively and the technology is very mature. Partial discharge tests of 750kV shunt reactors require a large power supply capacity. Partial discharge tests on site have been used in the past It is very difficult to do. Now, due to the wide application of frequency conversion series resonance technology and the successful development of low partial amplification power frequency conversion power supply, the field partial discharge test of 750kV shunt reactor can be carried out completely. [0003] The control system of the discharge test in the prior ar...
