Low profile mounting assembly and cabinet enclosures for rack relay mounted rectifiers

Claim 1

An enclosure for a single phase rectifier having an input transformer, a saturable reactor, at least one capacitor, input diodes, and other circuit components; wherein all of said transformer, reactor, at least one capacitor, diodes, and other circuit components, are physically mounted in said enclosure for electrical connection; and wherein said enclosure comprises: a chassis having a horizontal base and a vertical rear wall secured to each other so as to form a rigid two-sided frame, a door panel hingedly secured to the front edge of said horizontal base, and removable cabinet side walls and cabinet top cover arranged to be placed with said chassis and door panel so as to close said enclosure; wherein said input transformer is securely mounted to said vertical rear wall horizontally above said horizontal base, and is formed with a UI-shaped core having two legs projecting forwardly from said rear wall with a transformer coil mounted on each leg, and an air space between said transformer coils; wherein said saturable reactor is securely mounted horizontally to said vertical rear wall, and is formed with an EI-shaped core having three legs projecting forwardly from said rear wall with a reactor coil mounted on each leg, and an air space between adjacent reactor coils; wherein said at least one capacitor is mounted on said horizontal base; wherein all said other circuit components are secured to said chassis or to said transformer or said saturable reactor in such a manner that all electrical connections between all components of the single phase rectifier, and the input and output electrical connections to the single phase rectifier, are made at the front of said enclosure; and wherein cooling slots are provided in said horizontal base, said vertical rear wall, and at least one of said cabinet side walls and said cabinet top cover.
