ABSTRACT:
The high voltage transformer for the ignition system of an oil burner and the control system for the oil burner are packaged together in a single housing. The duty cycle of the transformer is discontinuous. The transformer core is of symmetric U-I configuration but the coil arrangement is asymmetric with a single primary coil being provided. The transformer is not potted, the core ends are free of coils, and one core end overlaps a circuit board for the control system to thereby foreshorten the overall package. Although the transformer is not potted, tight constraints against shorting of the high voltage secondary leads are maintained by provision of an insulator bushing means which is positioned in apposition to the transformer secondary coils by means of a bracket which also provides a mounting for the transformer core, the high voltage leads being drawn through the insulator bushing means and secured at terminal contacts at the lower ends of the bushing means. The entire package is hinged for movement into and out of working association with the ignition leads of an oil burner.
