Description

technical field

[0001] The invention relates to the on-line monitoring technology of nuclear power plant electric equipment, and more specifically relates to an inverter trigger card testing system and method. Background technique

[0002] Now Daya Bay, Ling Ao Phase I, and Ling Ao Phase II nuclear power plants generally use uninterruptible power supplies to ensure the safe and stable operation of the power plants. The inverter card is a very important part of the uninterruptible power supply. An important card for the normal operation of the system. Different types of inverter cards can be used for different power supply systems.

[0003] Inverter systems such as LNH, LNP, and LNG are commonly used equipment in Daya Bay and Ling'ao nuclear power plants. The main function of the inverter trigger card is to generate pulse signals through the excitation of external power signals to ensure that the thyristors of the inverter are normally turned on. The core card that successfu...
