Truck-mounted breakers intended for high-voltage lines and a method in connection to such lines

摘要

A truck mounted breaker for high voltage lines. The breaker is a kind in which a linear displaceable contact device, including a plurality of units, coacts with a stationary countercontact device which includes a corresponding number of countercontact units. The breaker is intended for high voltage lines. All countercontact units are supported by a stand common to the units. The stand also supports the linear displaceable contact device. This arrangement ensures correct alignment of all pairs of contact and countercontact units.
