PROCESS OF MANUFACTURE OF ARC EXTINCTION MODULE OF VACUUM SWITCH Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: arc chute is placed into insulating body of module, is fixed and module is sealed by tightening of sealing units. Then space between arc chute and insulating body in lower part of module is filled with solidifying polymer. Space up to upper sealing unit left after solidification is filled with insulation fluid of high viscosity heated to temperature exceeding its maximum temperature during switch operation. After this space above upper sealing unit is filled with solidifying polymer. EFFECT: improved safety of switch. 2 cl, 1 dwg
