摘要

本文分析了电容式电子技术存储器(CES)的充电过程,该存储器可以是现代高压设备(特别是电力电缆)的电气绝缘,在对绝缘施加高压时,通过漏电流值对其技术状态进行电流监测。共振型无变压器电子技术系统 (ETS) 用于产生这种电压,在该系统中,具有高 Q 因子的共振电感电容电路 (ICС) 可使交流电压成倍增加。对这种 CES 上的稳态电压和 ETS 电路中的瞬态电流进行了分析。使用 LTSpice 软件包对 CES 充电期间 ETS 电路中的瞬态过程进行了仿真建模。结果表明,ETS 输出电压和电流对时间的依赖性与模拟仿真的结果基本吻合。研究了负载电容与谐振电路电容之比对相对负载充电时间的影响,以及相应地对 ETS 功率的影响。研究发现,为了提高特定谐振类型的高压无变压器 ETS 功率,有必要提高 CES 容量与 ETS 谐振电路 ICС 容量之比。当使用带有谐振 ICC 的 ETS 来创建强大的放电装置(EDI)时,可以使用这种方法来实现获得具有独特工作特性的电火花微粉和纳米粉体的技术。在制造强力放电装置时,建议使用至少 10 的上述比率值。参考文献 31,图 5。

THE INFLUENCE OF THE CAPACITANCE OF THE SERIES RESONANT CIRCUIT ON THE POWER OF RESONANT-TYPE ELECTRICAL SYSTEMS FOR MONITORING THE INSULATION OF HIGH-VOLTAGE EQUIPMENT
It were analyzed the processes of charging the capacitive electro-technical storage (CES), which can be the electrical insulation of modern high -voltage equipment (in particular power cables) during the current monitoring of its techni-cal condition by the value of leakage currents when applying high voltage to insulation. The transformerless electro-technical system (ETS) of a resonance type, in which resonant inductive-capacitive circuit (ICС) with a high Q -factor carried out a multiple increase in AC voltage, was used to generate such voltage. Analytical expressions were obtained for the steady-state voltage on such CES and transient currents in the ETS circuit its charging. Simulation modeling of transient processes in the circuits of such ETS during CES charging was performed using the LTSpice software pack-age. It is shown that the dependences of the output voltage and current of the ETS on time, obtained by analytical ex-pressions, practically coincide with the results of simulation simulations. The influence of the ratio of the load capaci-tance and the resonant circuit capacitance on the relative load charging time and, accordingly, on the ETS power was studied. It was found that in order to increase the power of high -voltage transformerless ETS of the specified reso-nance type, it is necessary to increase the ratio of the CES capacity to the ICС capacity of the resonant circuit of the ETS. This approach can be used when using ETS with resonant ICCs to create powerful electric discharge installations (EDIs) for the implementation of technologies for obtaining electro-spark micro- and nanopowders with unique opera-tional properties. When creating powerful EDIs, it is suggested to use the value of the above-mentioned ratio at least 10. References 31, figures 5.
