Opti-G Fuse Flipper

Opti_G.jpg

Years of research have gone into the development of Cooper Power Systems Opti-G (Optimal Geometry) fuse flippers. Analysis of the flipper's motion and functional requirements has allowed for the optimization of their geometry and mechanical characteristics. The resulting design provides superior orchestration with the remainder of the expulsion fusing system.

Benefits

Elimination of leader whipping:
This phenomena is manifested by the operation of multiple fuses when only one fuse was required to operate. Ranging from a nuisance to a major operating concern, leader whipping can cause banks to trip off line without the benefit of alarm relay operation. In some cases, leader whipping has been responsible for sympathetic capacitor unit failures, tank ruptures, arcing between buswork, and high overvoltage generation.

Improved low-current clearing:
The positive ejection of the operated fuse link allows rapid dielectric strength buildup within the fuse tube, ensuring proper clearing even under low-current! low-energy conditions.

Elimination of Permanent Deformation:
Some conventional flipper spring designs, after having been left in a cocked position for many years, may permanently take up this shape and lose their flipper action. This can result in disastrous fuse restriking and improper clearing of faulted capacitor units.

Opti-G flippers are available in a number of styles for various mounting configurations. Supplied as standard equipment with Cooper Power Systems substation banks, these advanced technology flippers are ideal for PCB replacement/retrofit applications.
