Description

Technical field [0001] The invention relates to a test device for a thyristor phase selection device, which belongs to the technical field of electrical inspection. Background technique [0002] The thyristor phase selection switch test device controls the closing angle by controlling the phase of the trigger pulse of the thyristor, so as to meet the requirements of current and voltage waveforms required by the detection equipment. [0003] At present, the technology mainly adopted by the detection equipment is realized by manual operation through mechanical switches. The traditional mechanical switch cannot achieve arbitrary opening angle and output waveform control. For example, it is used in the thyristor phase selection switch device of the Shanghai Equipment Inspection Center under the Shanghai Electrical Equipment Research Institute (Group) Co., Ltd. [0004] With the advancement of technology, traditional testing equipment will be operated less and less manually, and will ...
