ABSTRACT:
A metal-encapsulated, gas-insulated switching installation is provided with at least one busbar system, the busbar system having an axis separation, and a circuit breaker, the circuit breaker being in the form of a pole and having a pole axis, the circuit breaker including at least one quenching chamber installed in a pole enclosure and at least one connection for the associated busbar system. The pole axis is arranged at a right angle to a surface of a foundation. The circuit breaker of the switching installation includes a modular circuit breaker pole. The modular circuit breaker pole includes an enclosure lower part having a first end and a second end, and at least one opening for connecting an isolator for a busbar system between the first end and the second end of the enclosure lower part, an enclosure upper part having a first end and a second end, at least one of the first end and the second end of the enclosure upper part being attachable to each of the first end and the second end of the enclosure lower part, and an enclosure cover attachable to at least one of the second end and the first end of the enclosure upper part. The enclosure lower part, the enclosure upper part, and the enclosure cover define at least part of a circuit breaker pole enclosure having a pole axis.
