Abstract
A rupture reduction system for fluid-immersed electrical equipment includes a turret for mounting of a bushing. The turret is expandable in volume in response to a surge in pressure of the fluid in the turret. The expansion volume can be provided by an expandable section of the turret, which may include a bellows.
Claims24
An apparatus, comprising:
- a turret mountable to a tank for electrical equipment, and further being mountable to at least one bushing for insulating at least one conductor connected to the electrical equipment, a volume between first and second ends of the turret for containing a fluid, and at least one section between the first and second ends of the turret that expands in volume in response to a pressure surge in the fluid within the turret to reduce occurrences of ruptures of the turret.
A transformer system, comprising:
- a tank including an internal space for housing one or more electrical components;
- a turret mounted to the tank;
- at least one bushing mounted to the turret to insulate one or more conductors that receive electrical current from the one or more electrical components;
- and
- a fluid in the tank and the turret, wherein the turret is expandable in volume in response to a pressure surge in the fluid in the turret.
2 more elements
The system of claim 21, wherein the at least one guide rod is fixed to a second flange connected to the bellows.
