Embodiment Construction
[0027] Throttle valve 1 is used with unpressurized windings and cores to improve the ability to impregnate them with liquid heat carrier 5 . After dipping, the leakage current through the insulator is reduced, the electrical breakdown resistance is increased, and the heat transfer from the heating element to the heat carrier 5 is maximized. Capacitor 10 may be located outside or inside tank 2 . In the second case, the heat from the capacitor is also transferred to the heat carrier 5 . As the heat carrier 5, any liquid substance such as transformer oil, glycerin, paraffin (liquid), etc. that does not damage the insulation of parts and materials located inside the storage tank 2 can be used. The spacer 4 is intended to dampen the effects of vibrations produced by the core of the throttle valve 1 .
[0028] When the switch 13 is closed, the electrical part of the heater 15 immediately goes into ferroresonant mode. It provides all circuit details and correct selection of AC pow...
