<p>PURPOSE:To enhance iron resonance suppressing effect and to remove an excess space by mounting a saturable reactor as an iron resonance suppressor on a low voltage lead bushing seat, and connecting a low voltage coil with the lead bushing of the coil. CONSTITUTION:A saturable reactor is mounted to surround a low voltage lead bushing seat inside a tank of the low voltage lead bushing seat. Insulating plates 16 having a plenty of electric insulation are disposed at both ends of a saturable reactor 15 inside a tank 8 of the low voltage lead bushing seat 14, a plurality of clamping parts 18 are disposed on the outer periphery of a metal retainer 17 and the reactor 15, and mounted on the seat 14. Thus, the lead of the reactor 15 can be extremely shortened as compared with the conventional one. Therefore, the resistance value of the reactor 15 including the leads decreases to increase the resistance loss when the reactor 15 operates as an iron resonance suppressor increases, thereby enhancing the suppressing effect.</p> |
