On the basis of the analysis of the flow mechanism of throttle tubes, the pressure drop model of the single-phase flow through the throttle tube is derived from the mass, momentum and energy conservation equations. Good agreement is found between the pressure drop model and the experimental results. The accuracy of the model gained in the experiment is highly satisfactory. Furthermore, it is pointed out that the main resistance loss of the single-phase flow through the throttle tube is that of the abrupt-enlargement,...

On the basis of the analysis of the flow mechanism of throttle tubes, the pressure drop model of the single-phase flow through the throttle tube is derived from the mass, momentum and energy conservation equations. Good agreement is found between the pressure drop model and the experimental results. The accuracy of the model gained in the experiment is highly satisfactory. Furthermore, it is pointed out that the main resistance loss of the single-phase flow through the throttle tube is that of the abrupt-enlargement, and the inlet abrupt-contraction resistance should not be neglected at all. Besides, the frictional resistance must be taken into account for the longer throttle tubes.

The contact resistance between contacts is composed of contraction resistance and velamen resistance.The contraction resistance is one o the very import ant pants and effects electricd life of apparatus directly.The traditional measuring method is that passing a large current through contacts so that velamen resistance is eliminated,then contact resistance is nothing but contraction resistance.But the apparatus will be impaired.The paper gives no damnification meterage way of contraction resistance based on the voltage across contacts.When the AC.current moves through contacts,the voltage across contacts includes fundamental voltage and third harmonic voltage.Because the third harmonic voltage depends on contact resistance,the value of the contact resistance can be obtained through measuring the third harmonic voltage and Using FFT(Fast Fourier Transform)method.

电器触点间的接触电阻包括收缩电阻和薄膜电阻。其中收缩电阻值取决于触点的接触情况 ,它是影响电器电寿命的重要因素之一。传统的检测方法是让触点接通一个较大的电流 ,以消除薄膜电阻 ,此时触点的接触电阻即为收缩电阻。该种检测方法对电器触点有一定的损失。当交流电流流过闭合触点时 ,触点间电压降包含三次谐波成分。而三次谐波的大小依赖于收缩电阻的大小。根据这个特点 ,本文阐述采用计算机技术以及快速傅里叶变换 (FFT)的信号处理技术 ,解决三次谐波电压的检测问题 ,从而实现对电器触点无伤害的收缩电阻检测方法
