Сучасні методи та засоби моніторингу та діагностики кабельних ліній напругою 6-35 кВ

Abstract

In this diploma work investigational methods and facilities of places of damages of cable busses. The methods of distance-finding from the place of measuring (to beginning of cable) to the site of damage are named relative methods. Relative methods do not guarantee high exactness of location damage, but specify an area which a damage is in, and enable to utillize absolute methods in this area, that methods by which directly can be defined site of damage. A laboratory is investigational electrical engineering movable combined ЭТЛ-35К. Feed ЭТЛ-35К made from the industrial monophase network of 220v, 50 Hertzs. A feed is assumed ЭТЛ-35К from the autonomous generator of elektropostachannya of the proper power. Apparatus and devices ЭТЛ-35К counted on exploitation in districts with a temperate climate. And also comparison of lopustimikh values is executed and instrumentation on the rizkhnikh segments of cable bus this laboratory.
