  • 概述

First, an overview

介质损耗和介电常数是各种电瓷、装置瓷、电容器等陶瓷,还有复合材料等的一项重要的物理性质,通过测定介质损耗角正切tanδ及介电常数(ε),可进一步了解影响介质损耗和介电常数的各种因素,为提高材料的性能提供依据;仪器的基本原理是采用高频谐振法,并提供了,通用、多用途、多量程的阻抗测试。它以单片计算机作为仪器的控制,测量核心采用了频率数字锁定,标准频率测试点自动设定,谐振点自动搜索,Q值量程自动转换,数值显示等新技术,改进了调谐回路,使得调谐测试回路的残余电感减至zui低,并保留了原Q表中自动稳幅等技术,使得新仪器在使用时更为方便,测量值更为精确。仪器能在较高的测试频率条件下,测量高频电感或谐振回路的Q值,电感器的电感量和分布电容量,电容器的电容量和损耗角正切值,电工材料的高频介质损耗,高频回路有效并联及串联电阻,传输线的特性阻抗等。

Dielectric loss and dielectric constant is a variety of porcelain, porcelain device, capacitor, etc. ceramic and composite materials, such as an important physical properties, by measuring the dielectric loss angle tan delta and dielectric permittivity (epsilon), further understanding of the factors in the influence of dielectric loss and dielectric constant, in order to improve the properties of materials provides the basis; equipment and the basic principle is using high frequency resonance method, and provides, GM, multi-purpose, multi range impedance test. It to single chip computer as the instrument control, core measurements using digital frequency locking, frequency standard test point automatic setting, resonant point automatic search, Q value range automatic conversion, numerical display and other new technologies, improved the tuning circuit, so as to reduce to a minimum the tuning circuit for testing residual inductance and retains the original Q table in the automatic amplitude stabilizer technology, makes the new instrument in use is more convenient and the measured values are accurate. The instrument can under high frequency test conditions, measurement of high frequency inductive or resonant loop of the Q value, inductance and distributed capacitance of inductor, capacitor of capacitance and loss angle tangent value, electrical materials, dielectric loss in high frequency and high frequency circuit in parallel and series resistance, transmission line characteristic impedance.
