Vacuum contactor operation with parallel connection of independent consumers

The design, operation and use are characterized for high voltage vacuum contactors in underground coal mines endangered by methane and coal dust explosions. Design of a vacuum contactor is shown in a scheme. Vacuum contactors are superior to electromagnetic contactors. The drivers of the high voltage vacuum contactormarket are influenced by the trends in the process industries, manufacturing industries, commercial and large residential sectors that use HVAC systems.This market study covers medium voltage vacuum contactors of various voltage ratings, applications, and end-users for arriving at the global market size from 2013 to 2020. In terms of voltage rating, the vacuum contactor market is segmented into four divisions: less than 5kV, 5-10 kV, 10-15 kV and more than 15kV.In terms of region, the single phase vacuum contactor is segmented on the basis of its market presence in the following regions namely North America, South America, Europe, Asia-Pacific and Middle East & Africa. These regions are further classified on the basis of top countries and their end user analyses have been made. Few countries in Europe are shifting towards renewable sources for power generation that has boosted the low voltage vacuum contactor market in the region. Vacuum contactor finds vast application in industrial and commercial sectors as well.
