变压器温控器接点误差校验的相关问题探讨

Related Issue Discussion of Contact Errors Checking for Transformers Thermometers

在进行变压器温控器检定时,不仅要保证温度指示值的准确性,还必须认真考察温控器内部的接点动作及返回的准确性和可靠性。通过分析国标检定规程、行业制造规程以及实际试验数据,提出了符合电力变压器运行要求的温控器接点检定方法,并且针对现场检定提出了满足规程要求的接点快速检测方法。

When calibrating thermometers for transformers,we should guarantee not only the precision of the indication,but also the the precision and reliability of the contact.By analysing the national standard calibration regulation,the industry manufacturing standard and the practice tests data,we propose the contacts calibrating methods specific to thermometers for transformers.A fast test method for locale contacts calibration is also put forward.
