DRY TYPE ECONOMIZER

摘要

A dry type economizer includes an economizing unit formed of a plurality of bodies, each body including a silicon-steel layer, an insulating layer surrounding the silicon-steel layer, a plurality of windings surrounding the insulating layer, and reactance elements and reactance filter converters respectively electrically connected to the windings, each winding being formed of a wire material having an increased wire diameter larger than a standard wire diameter of 3.5 mm. Thus, each body eliminates the use of any insulating oil, and has an increased volume to provide a large surface area in contact with the atmosphere for quick dissipation of heat during operation of the reactance elements.

主权项

1. A dry type economizer comprising at least one economizing unit, each said economizing unit comprising:
a plurality of bodies, each body of said plurality of bodies comprising a silicon-steel layer, an insulating layer surrounding said silicon-steel layer, and a plurality of windings surrounding said insulating layer and adapted for energizing reactance elements and reactance filter converters, each said winding being formed of a wire material having an increased wire diameter larger than a standard wire diameter of 3.5 mm; two silicon-steel beams respectively mounted at opposing top and bottom sides of said bodies and connected with opposing top and bottom ends of the silicon-steel layers of said bodies; and a plurality of elongated flanges, one elongated flange of said plurality of elongated flanges being located on one side of a periphery of each body of said plurality of bodies, a plurality of reactance element input/output casings mounted in and equally spaced along a length of each said elongated flange of the plurality of elongated flanges, and a plurality of filter converter devices mounted in each said elongated flange of the plurality of elongated flanges, an uppermost filter converter device of said plurality of filter converter devices is located between an uppermost pair of reactance element input/output casings of said plurality of reactance element input/output casings and a lowermost filter converter device of said plurality of filter converter devices is located between a lowermost pair of reactance element input/output casings of said plurality of reactance element input/output casings for use as reactance filter converters.
