【摘要】 作为实物计量器具的标准电容器,环境温度的变化是引起其容量变化的主要因素。依据JJG183-1992《标准电容器检定规程》,对标准电容器进行了温度系数试验,验证了不同介质材料制造的标准电容器的温度特性,为标准电容器的检定校准工作提供了试验依据。更多还原

【Abstract】 Standard capacitor is a kind of material metrology instrument,the change of environmental temperature is the main factor of capacitance variation.According to JJG183-1992 Verification Regulation of Standard Capacitors,we performed the test on temperature coefficient of standard capacitors.The test verifies the temperature characteristic of the capacitors which are made of different dielectric materials.更多还原
