High voltage switches are indispensable in power system which will control and protect the high voltage lines. According to the research of high voltage switch equipment accident rate in the international conference on power grid for according, the high voltage switch equipment mechanical failure accidents accounted for more than 70%. Thus, it is meaningful to research the switch monitoring technology and develop an integration device with easy installation and reliable data transmission. In this paper, a new type of non-contact current sensor is used to develop the online monitoring system for the mechanical characteristics of HV switches, which will monitor and analyze the action characteristics of the opening coil, closing coil and energy storage motor.

In order to detect switch contact temperature of high voltage switch cabinet in the operation of the cabinet, this paper puts forward a wireless measurement way to solve the measuring temperature problem of high voltage switch of the switch contact using magnetic field coupling idea. The temperature danger can be achieved in time to reduce switch burn injury. The device is mainly composed of temperature acquisition part and temperature display part. The two parts are connected by wireless data transmission. By test determination, the method is accurate and convenient to measure the temperature of the switch contact and then completely eliminate major accidents caused by switch temperature rise.

ABSTRACTMotivated by the benefits of optical data transmission, materials for the electromagnetic spectral window from approximately 0.6 to 4.0 microns are being explored by many investigators. I will review materials for the spectral regions surrounding this window. In these spectra regions a primary interest is optical power transmission. Optical power transmission in the UVand far IR has significant application for materials and device fabrication and characterization. Sources such as eximer and CO2 lasers provide potential sources of very high power.Based on bonding and atomic mass considerations, materials for transmission in these windows can be approximated. Methods for taking advantage of the properties of materials such as reflectivity have the potential for interesting lightguiding structures such as hollow core lightguides. Materials currently contemplated for use in these wavelength regions and properties of potential materials will be discussed.

Direct light triggering of 4H-SiC thyristors with a 365 nm UV LED was demonstrated. Two different structures with etched and non etched gate were successfully tested. The current rise time was less than 100 ns and the delay time as short as 1.5 μs. The optical energy density necessary to switch-on a thyristor has been studied for different optical power densities and bus voltages. This work shows that the UV LED technology is becoming sufficiently powerful to switch-on SiC thyristors. Thus, an alternative, less expensive and more compact gate light source than UV laser is now possible. This can be of particular interest for very high voltage and pulse power electronic applications.

<span lang="EN-US">A concept of data transmission within downhole telemetry systems in oilfield industry through power lines is presented. Based on this concept, MATLAB/Simulink models simulating communication lines in downhole telemetry systems are built, which can be used as prototypes for development of real systems. The most appropriate signal modulation methods for data transmission in downhole telemetry systems are suggested and discussed. The influence of high-voltage interference on signal transmission through power line from downhole unit to ground based unit is simulated. Usage of error-correcting coding methods for data transmission such as Hamming code, Reed-Solomon code, BCH code is suggested, and its efficiency is demonstrated.</span>
