FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to switching equipment. Device can be used in closed electrical substations of voltage 35 kV and higher, for which there is dependence of cost of structure on area and volume of structure. Electric substations also use a switch with built-in current transformer, used in measurement circuits or in relay devices. Invention also simultaneously uses a switch without built-in current transformers, in this case additional equipment is installed – current transformer, as well as overvoltage limiters.
EFFECT: technical result is reduction of production area for installation of support elements of switch, circuit breaker and associated other equipment due to compactness thereof.
