Research on Detection Method for Grid Power Transformers of Carbon Ion Therapy System

网电源变压器是碳离子治疗系统内的主要安全器件,也是电气安全检测中的关键项目,对碳离子治疗系统整体安全有效影响重大。本文结合检测经验并以GB 4793.1-2007《测量、控制、和实验室用电气设备的安全要求第1部分:通用要求》中4.4.2.6为依据,对网电压变压器主要检测项目(短路、过载、绕组温升)的试验准备、试验要求、检测方法进行了梳理和论述,提出了过载试验负载的解决方案,以期为碳离子治疗系统注册检测工作准备和实施提供参考。

The grid power transformer is the main safety device of carbon ion therapy system, and also the key item of electrical safety inspection, which has a great influence on the overall safety and effectiveness of carbon ion therapy system. Based on the testing experience and clause 4.4.2.6 of GB 4793.1-2007 Safety requirements for electrical equipment for measurement, control, and laboratory use-Part 1: General Requirements, the paper discusses the test preparations, requirements and methods of the main testing items(short-circuit, overload, winding temperature rise) of the grid voltage transformers and proposes solutions for overload test loads in order to provide reference for the preparation and implementation of carbon ion therapy system registration and detection work.
