Abstract

The methodology of the Murman-2018 experiment is considered. The technique of the study is based on the distance principle of deep sounding combined with frequency and audio magnetotelluric soundings. Two mutually orthogonal grounded transmitting lines, 1.6 km and 1.9 km in length, were powered by an Energiya-4 generator, which was used as a controllable electromagnetic field source . The main focus of the paper is the description of the self-powered 29 kW Energiya-4 generator with an output voltage up to 1200 V, developed at NERC KSC RAS. The paper discusses experience of using the generator to solve of fundamental problem of studying the nature of the deep geophysical boundaries in the Archean crust of the Murmansk block in the Murman-2018 experiment. A block diagram of the Energiya-4 generator is presented and its operating principle briefly described.

Murman-2018实验的方法论

摘要

考虑了Murman-2018实验的方法。这项研究的技术基于深度探测的距离原理，并结合了频率和音频大地电磁测深。两条互相正交的接地传输线（长度分别为1.6 km和1.9 km）由Energiya-4发电机提供动力，该发电机被用作可控电磁场源。本文的主要重点是对由NERC KSC RAS开发的，输出电压高达1200 V的自供电29 kW Energiya-4发电机的描述。本文讨论了使用生成器解决在Murman-2018实验中研究摩尔曼斯克区块太古宙地壳深部地球物理边界性质的基本问题的经验。
