Title: GAS-INSULATED MEDIUM VOLTAGE SWITCHGEAR WITH A CIRCUIT BREAKER POLE PART ARRANGEMENT
Abstract:
The invention relates to a gas-insulated medium voltage switchgear with a circuit breaker pole part arrangement in a gastight compartment of the switchgear, and with a drive arrangement for switching actuation of the circuit breaker, wherein the drive as well as the pole part arrangement is fixed on a common plate or frame, which is provided with a gastight sealing, and is closing the aforesaid compartment gastightly in such, that in the completely mounted position of the plate or frame, the pole parts are positioned inside, and the drive is positioned outside the aforesaid gastight compartment, according to the preamble of claim 1. In order to overcome constructural disadvantages, which may coincidently lead to further advantages in a method of assembling such a medium voltage vacuum circuit breaker for gas-insulated switchgear, the in invention is, that a standarized circuit breaker drive (8) is adaptable to switchgear arrangements with different pole distances (x, y), and that the plate or frame (2) is provided with holes, in which gastight mechanical feedtroughs (3) are arranged in, through which the drive (8) is coupled with each of the vacuum interrupters in the pole parts (1), and that by predefinable positioning of the holes, the plate or frame (2) can easily be adapted to the pole distance (x, y) in the gastight compartment.
