Abstract
A device for degassing and brazing preassembled vacuum interrupters in only one brazing operation includes a base plate having at least one brazing site which features an opening of the base plate for connecting a suction pump and a bell which covers the opening and can be put on the base plate and lifted off. The bell is surrounded on the outside by an excitation coil to which medium- or high-frequency energy can be applied. The device includes a medium- or high-frequency generator for the excitation coil and with a cylindrical tubular susceptor arranged inside the bell for receiving at least one preassembled vacuum interrupter.
Claims20
A device for degassing and brazing at least one preassembled vacuum interrupter in one brazing operation, the device comprising:
- a plurality of brazing sites, each brazing site including:
- an opening defined by a base plate for connecting a suction pump;
- a bell removably disposed on the baseplate for covering the opening;
- and
- an annular susceptor disposed inside the bell capable of receiving the at least one preassembled vacuum interrupter;
- an excitation coil capable of circumscribing each bell and capable of receiving medium- or high-frequency energy, the excitation coil being movable to each of the brazing sites in succession and/or at random;
- and
- a medium- or high-frequency generator for the excitation coil.
