  • Patent number: 5269055
    Abstract: In the course of the assembly of a circuit-breaker pole, the individual parts of a housing are stacked loosely one on top of the other and fixedly positioned. This fixing can be accomplished by applying subatmospheric pressure or a partial vacuum within the housing and/or by means of a holding device. Spaces open in the upward direction and located between a fitting and a support insulator as well as between a fitting and a quenching-chamber insulator are then filled with casting material. After this casting material has at least partially hardened, the circuit-breaker pole is turned upside down by rotating the holding device about a horizontal axis, whereupon spaces now open in the upward direction and located between a fitting and the quenching-chamber insulator as well as between a fitting and the support insulator are filled with casting material.

  • Patent number: 4808910
    Abstract: The current converter or transformer component of a high voltage measurement transformer comprises a primary lead or conductor which is surrounded by secondary windings or optical conducting elements. The primary and secondary components of the current converter or transformer component are housed in a casing having an integrally formed entry duct for the secondary leads. The secondary components of the current converter or transformer component are surrounded by plastic or synthetic insulation material. This insulation material or insulation also surrounds a channel for the secondary leads extending completely through the entry duct. The primary lead or conductor is provided with connecting flanges at both ends for mechanically or electrically connecting the high voltage measurement transformer to a high voltage or high power circuit breaker or similar device.
