根据有关技术文件的规定:内燃机车蓄电池组对地绝缘电阻的阻值,架修时不低于17000欧;定修时不低于8000欧;定修不互换蓄电池组时不低于3000欧。每次检修时都必须使用内阻为30000欧的直流电压表,分别测量U、U_1、U_2(见电阻表下面的公式)的三项电压值,然后代入其计算公式,求出R_φ值。在检修过程中既要维修保养,又要计算阻值,工作比较麻烦。我们从长期工作实践中,摸索出一种办法,把三项电压的变量值合并为U和(U_1+U_2)两项,从公式中我们知道R_x的值是U和(U_1+U_2)的函数,这样便可以编制出一
According to the provisions of the relevant technical documents: Diesel locomotive battery insulation resistance to the resistance, shelf repair time of not less than 17000 Europe; repair time not less than 8000 Europe; repair not interchangeable battery pack when not less than 3000 Europe . Each maintenance must use the internal resistance of 30000 ohms of the DC voltage meter, respectively, measuring U, U_1, U_2 (see resistance formula below) the three voltage values, and then into its calculation formula, find R_φ value. In the maintenance process, it is necessary to maintain, but also calculate the resistance, work is too much trouble. From the long-term working practice, we explore a way to combine the three voltage variables into U and U_1 + U_2. From the formula, we know that the value of R_x is a function of U and (U_1 + U_2) , So that we can prepare a
