Abstract

Provided in the invention is a charging protection device comprising a rectifying and filtering module (1), an overload signal collecting and converting circuit (5), an energy acquisition circuit (6),a determination circuit (4), and a main charging loop (2). The output terminal of the rectifying and filtering module (1) is connected with the main charging loop (2). The overload signal collectingand converting circuit (5) is used for collecting an overload signal, carrying out pulse conversion processing on the overload signal, and outputting an overload control signal. The energy acquisitioncircuit (6) is configured to receive the overload control signal, carry out electric energy collection on the output terminal of the rectifying and filtering module (1), store the energy, and outputa voltage control signal. The determination circuit (4) is used for receiving the voltage control signal, carrying out voltage reversal processing, and outputting an overload control signal. The maincharging loop (2) is used for receiving the overload control signal and performing charging starting or closing. According to the invention, overload protection of the main charging loop is realized and the overload signal collecting and converting circuit is integrated into a chip U357, so that the stability is improved.

Description

technical field [0001] The invention relates to the technical field of charging equipment, in particular to a charging protection device. Background technique [0002] High-speed railways, referred to as high-speed railways, refer to railways with high infrastructure design speed standards that allow trains to run safely and at high speeds on the tracks. The operating speed of trains is above 200km / h. [0003] High-speed rail has different regulations in different countries, different times, and different scientific research and academic fields. The National Railway Administration of China defines China's high-speed railways as passenger train-dedicated railways with a design speed of more than 250 kilometers per hour (including reservations) and an initial operating speed of more than 200 kilometers per hour, and issued the corresponding "High-speed Railway Design Specifications" document. The National Development and Reform Commission of China defines China’s high-speed r...
