近日，由特变电工沈阳变压器集团有限公司制造的徐大堡核电厂3号机组首台（A相）主变压器抵达徐大堡核电现场。

主变压器是将发电机发出的低电压大电流电能转换成高电压小电流送入电网的关键设备，同时也承担着在发电机停运期间将电网外部电源转化为厂房内设施主供电电源的功能。主变压器的到场是项目二级里程碑节点之一，为徐大堡核电项目3号机组按期实现投运发电奠定了良好的基础。

辽宁核电设备采购处将继续在公司党委、总经理部的坚强领导下，强化“整体·协同”，与设备厂家加强沟通协作，积极协调资源，有序推进设备制造、验收及发运工作，为机组安装调试工作提供有力保障。

Recently, the first (Phase A) main transformer of Unit 3 of Xudabu Nuclear Power Plant, manufactured by TBEA Shenyang Transformer Group Co., Ltd. arrived at the site of Xudabu Nuclear Power Plant.

The main transformer is the key equipment that converts the low-voltage and high-current electric energy from the generator into high-voltage and small-current and sends it to the power grid. At the same time, it also takes on the function of converting the external power supply of the power grid into the donor power supply in the plant during the outage of the generator. The arrival of the main transformer is one of the second-level milestone nodes of the project, which lays a good foundation for Unit 3 of the Xudapu nuclear power Project to realize the commissioning of power generation on schedule.

Liaoning Nuclear Power Equipment Procurement Department will continue to strengthen the "overall cooperation" under the strong leadership of the company's Party committee and general manager Department, strengthen communication and cooperation with equipment manufacturers, actively coordinate resources, orderly promote equipment manufacturing, acceptance and shipping, and provide a strong guarantee for the installation and commissioning of units.
