摘　　要：温升试验是保证变压器安全运行极为重要的试验方法之一,而温升试验的相互负载法是被试品以与实际运行工况相同的额定满功率的试验状态的试验方法,能获得准确可靠的试验数据。本文介绍了影响干式变压器温升试验结果的因素,分析了温升试验的相互负载法,并给出了应用实例。Temperature rise test is one of the most important test methods to ensure the safe operation of transformer,and the mutual load method of temperature rise test is the same test method as the actual operation condition with rated full power,which can obtain accurate and reliable test data.This paper introduces the factors affecting the temperature rise test results of dry-type transformer,analyses the mutual load method of temperature rise test,and gives an application example.
