摘　　要：ZPW-2000A轨道电路调谐设备的参数主要由极阻抗和零阻抗组成,极阻抗和零阻抗的实部在十几毫欧到几十毫欧范围内,虚部在十几毫欧到几百毫欧范围内,调谐设备内某个器件参数的微小偏差,会使设备的阻抗数值产生数毫欧的变化。每台调谐设备在生产过程中,需将极阻抗和零阻抗参数控制在指标范围内,逐台生产、逐台调试的方法已不满足高效率生产的要求。找到正确的选配方法,对实现调谐设备批量调试、生产尤为重要。The parameters of ZPW-2000A track circuit tuning equipment are mainly composed of polar impedance and zero impedance.The real part of the polar impedance and zero impedance ranges between ten milliohms and dozens of milliohms,while the imaginary part ranges between ten milliohms and hundreds of milliohms.The small deviation of a device parameter in the tuning equipment will cause a change of several milliohms in the impedance value of the equipment.In the production process of each tuning equipment,the parameters of polar impedance and zero impedance need to be controlled within the specifi ed range.The method of one-by-one production and commissioning no longer meets the requirements of efficient production.Finding the correct selection and matching method is particularly important for realizing batch debugging and production of tuning equipment.
