Abstract

A circuit interrupting device including a loop split interrupter for interrupting a loop split circuit with a high current and a low voltage and a quick whip interrupter for interrupting a charging circuit with a low current and a high voltage.

First claim

What is claimed is:

1. A circuit interrupting device comprising:
a loop split interrupter for interrupting a loop split circuit in a primary circuit with a high current and a low voltage; and
a quick whip interrupter for interrupting a charging circuit in the primary circuit with a low current and a high voltage.

2. The circuit interrupting device recited in claim 1 , further comprising:
a blade carrying a primary current for the primary circuit; and
a pickup assembly bridging the current from said blade to one or more of said loop split interrupter and said quick whip interrupter.

3. The circuit interrupting device recited in claim 2 , wherein the loop split interrupter includes two or more spark gap rods, wherein a spark gap is disposed between the two or more spark gap rods.

4. The circuit interrupting device recited in claim 1 , wherein said loop split interrupter includes a single bottle interrupter.

5. The circuit interrupting device recited in claim 2 , wherein the blade is rotatable between a first position and a second position, wherein, in a first position, the blade conducts the primary current for the primary circuit and, in a second position, the blade does not conduct current for the primary circuit.

6. The circuit interrupting device recited in claim 1 , wherein the quick whip interrupter includes a mechanical energy storage mechanism.

7. The circuit interrupting device recited in claim 6 , wherein the mechanical energy storage mechanism comprises a torsion spring.

8. An electrical switch, comprising:
an electrical terminal including a terminal contact;
a loop split interrupter;
a quick whip interrupter; and,
a blade rotatable from an open blade position to a closed blade position;
wherein the blade engages the terminal contact in the closed contact position and wherein the electrical terminal, the loop split interrupter, and the quick whip interrupter are electrically coupled to each other via a primary circuit.

9. The electrical switch of claim 8 , further comprising a pickup assembly bridging the current from the blade to one or more of the loop split interrupter and the quick whip interrupter.

10. The electrical switch of claim 8 , further comprising two or more spark gap rods, wherein a spark gap is disposed between the two or more spark gap rods.

11. The electrical switch of claim 8 , wherein the loop split interrupter includes a single bottle interrupter.

12. The electrical switch of claim 8 , wherein the blade conducts a current in the closed blade position and does not conduct a current in the open blade position.

13. The electrical switch of claim 8 , wherein the quick whip interrupter includes a mechanical energy storage mechanism.

14. The electrical switch of claim 13 , wherein the mechanical energy storage mechanism comprises a torsion spring.
