节电型自适应10～20kV系统的高压带电显示器的研制

从解决配网10kV升级至20kV时相应配套高压带电显示器的使用角度出发,经过对原有10kV系统中使用的电显原理及实物进行论证分析,利用计算机仿真并结合实际制作验证,研制设计出了一种节电型、长寿命LED发光的高压带电显示器。在不更换器件的前提下成功解决了输配电网升压后高压带电显示器应用的实际问题,具有一定的实用和推广价值。

High-Voltage Presence Indicating Systems Development for Power-Saving Self-Adaptive from 10 kV to 20 kV System

From the corresponding point view of the use of high-voltage presence indicating systems (VPIS) when the distribution net-work upgrades from 10 kV to 20 kV, and after theoretical analysis of VPIS principle and the circuit structure used in the previous 10 kV system, the computer simulation was adopted and the practical way of producing test was confirmed. A power-saving long-life LED-displaying VPIS was designed. On the premise of non-changing device, the actual problems of VPIS application were solved succ...
