Abstract

The invention provides the combined structure of vacuum circuit interrupter apparatus and current transformer switching apparatus. A coil, associated with the vacuum circuit interrupter apparatus for extinguishing the arc formed when two contact rods are separated to interrupt an electrical circuit, is also utilized as a primary winding of at least one current transformer, which provides a switching function unrelated to the enhancement of the arc extinguishing characteristics produced by the magnetic field generated by the coil. In an embodiment of the combined apparatus, the vacuum circuit structure, including the coil, is embedded in a synthetic resin body which also includes plug terminals connected to one of the contact rods and the end of the coil in order to provide a switching signal output. Additionally, the synthetic resin body includes two inverted U-shaped extensions having an aperture on each side of the vacuum circuit interrupter housing. The windings of the coil are embedded in the U-shaped extensions and a ring core and secondary winding, forming part of the current transformers, are mounted within each of the apertures.
