METAL-ENCLOSED PRESSURIZED GAS-INSULATED HIGH-VOLTAGE POWER STATION

摘要

20365-2927 In metal-enclosed pressurized gas-insulated high-voltage power stations housings having longitudinal axes at an angle to each other must often be connected to one another via an adapter. Two rings abutting one another at end faces serve as the adapter, these rings each having bores on an inner and an outer reference circle and each connected to flanges of the housings on the inner reference circle and to one another on the outer reference circle. The hole spacings .beta.i, .beta.a of the bores on the two reference circles vary such that they can be added up to 90.degree. or 60.degree.. On one of the rings the bores on the outer reference circle are designed as elongated holes, their length resulting from an angle .gamma. = or All angles ?.alpha. between the longitudinal axes which lie in the range of ? 90.degree. or ? 60.degree. can be set by means of the adapter.
