Abstract

The invention discloses a simulation test device of a mixed on-load tap-changer thyristor module. The simulation test device comprises a hysteresis control current source module, a control module, a data acquisition module, and a test object module. Under the control of the control module, the hysteresis control current source module is used to apply test current to the test object module. The data acquisition module is used to acquire signals output by the hysteresis control current source module and the test object module, and the signals are transmitted to the control module. The control module is used to control a single phase inversion H bridge in the hysteresis control current module according to the signals transmitted by the data acquisition module. The simulation test device is advantageous in that required equipment is less, and functions can be added automatically according to demands, and stronger adaptability is provided.

Description

technical field [0001] The invention relates to a simulation test device, in particular to a simulation test device for a thyristor module of a hybrid on-load tap changer. Background technique [0002] The thyristor-assisted arc-extinguishing hybrid transformer on-load tap-changer adds a thyristor module on the basis of an ordinary oil-immersed on-load tap-changer. When switching, the thyristor module replaces the freewheeling of the mechanical contact, which has the function of reducing contact ablation. and transformer oil contamination advantages. In the hybrid on-load tap-changer, the thyristor module is the core component, and it is very meaningful to develop its testing and selection methods. [0003] The thyristor module turns on and off the current like a switch, and shuts off the water flow like a gate. Its core function is a word "gate"; so the thyristor has two states, one is the on state, and the other is the off state; how to change the state of the thyristor ...
