Abstract

504,195. Transformers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 23, 1937, No. 29025. Convention date, Oct. 36,1936. [Class 38 (ii)] A welding transformer which is operated intermittently and at a loading much in excess of its normal continuous loading rate, has a contactmaking thermometer 13, placed adjacent one of the windings, which completes a circuit to give an optical or acoustic indication when the temperature exceeds a given amount. In the form shown, a lamp 12 is provided and is supplied from an auxiliary winding. The transformer core is provided with magnetic shunts to give high leakage reactance and the primary may be tapped to enable the voltage to be regulated. A press-button switch is provided to enable the lamp to be tested.
