摘要:
A heating element formed from at least two wires twisted together. The twisted wires are preferably shaped in a helical configuration and mounted within a quartz tube.
摘要:
A resistor and a manufacturing method thereof are disclosed. Since a ceramic tube formed of a ceramic material is used and the ceramic tube is joined to sealing electrodes by use of brazing rings, joining strength and durability of the resistor are considerably improved. The resistor may be stably used at a high voltage due to excellent heat dissipation characteristics thereof.
摘要:
A device for the protection of electric power resistances assembled in a battery using rods, insulating guns and isolators all housed within a dust tight and water jet tight parallelepipedic metallic housing, containing only air for cooling the resistances; fixing screws are provided for assembling and holding the various panels together and seals with a cut-out are provided in all assembly areas between the panels so that electrical continuity between two adjacent parts of the panels is achieved through despite any possible loosening; a compression element is interleaved between two adjacent parts of the panels to be assembled, at right angles to passages for the fixing screws, and the compression element is interleaved between the two adjacent parts for producing on opposite faces of the parts a force greater than the rigidity of the parts and housed in the thickness of the cut-out in the seals providing for contact tightness of the parts of the panels without limiting efficiency.
