Separable loadbreak design with enhanced ratings
A new and improved separable loadbreak connector system capable of providing higher switching and fault close ratings by various means of dividing the arc energy within the connector system.
1. A loadbreak connector assembly for use with a moveable probe having a probe-conducting portion, comprising:
a first contact zone;
a second contact zone that is spaced apart from the first contact zone, each of the first and second contact zones including electrically conductive material, the second contact zone being in a fixed position relative to the first contact zone;
an insulated zone located between the first contact zone and the second contact zone; and
wherein, in response to the probe being moved relative to the second contact zone, electrical contact is made between (i) the probe conducting portion and the second contact zone and between (ii) the first contact zone and the second contact zone.
2. The loadbreak connector assembly of claim 1 , further including a floating contact moveable relative to the first and second contact zones, the floating contact provides the electrical contact between the first contact zone and the second contact zone in response to the probe being moved.
3. The loadbreak connector assembly of claim 2 , wherein the probe directly engages and moves the floating contact as the probe advances from a first position to a second position within the second contact zone.
4. The loadbreak connector assembly of claim 1 , wherein the probe includes an arc-quenching portion that engages the floating contact, the arc-quenching portion separating the floating contact from the probe conducting portion.
5. The loadbreak connector assembly of claim 1 , wherein the second contact zone has two female contact regions, one female contact region for engaging the floating contact and the other female contact region for engaging the probe conducting portion.
6. The loadbreak connector assembly of claim 1 , wherein the probe is configured in accordance with ANSI/IEEE 386.
7. The loadbreak connector assembly of claim 2 , further include a spring system coupled to the floating contact for urging the floating contact back to an initial position for the floating contact when the probe moves back to its original position.
8. The loadbreak connector assembly of claim 2 , wherein the floating contact further includes an arc-quenching portion.
9. The loadbreak connector assembly of claim 1 , further including an arc-quenching portion located within the insulated zone when the probe is in its original position.
10. The loadbreak connector assembly of claim 1 , wherein an arc density when making or breaking an electrical connection within the connector assembly is divided between (i) the electrical contact at the probe conducting portion and the second contact zone, and (ii) the electrical contact at the first contact zone and the second contact zone.
11. The loadbreak connector assembly of claim 1 , wherein the probe is a multi-piece probe having a proximal conductive portion, a distal conductive portion, and an arc-quenching portion located between the proximal conductive portion and the distal conductive portion.
12. The loadbreak connector assembly of claim 11 , wherein the multi-piece probe further comprises a proximal arc-quenching portion proximal of the proximal conductive portion.
13. The loadbreak connector assembly of claim 11 , wherein, in response to the probe being advanced from a first position to a second position, the proximal conductive portion makes the electrical contact between (ii) the first contact zone and the second contact zone.
14. The loadbreak connector assembly of claim 13 , wherein the distal conductive portion is the probe conducting portion making the electrical contact with the second contact zone in response to the probe being advanced to the second position.
15. A loadbreak connector assembly, comprising:
a first contact zone;
a second contact zone that is spaced apart from the first contact zone, each of the first and second contact zones including electrically conductive material, the second contact zone being in a fixed position relative to the first contact zone, the second contact zone is capable of receiving a moveable conductor;
an insulated zone located between the first contact zone and the second contact zone; and
wherein, in response to the conductor moving relative to the second contact zone, electrical contact is made between (i) the conductor and the second contact zone and between (ii) the first contact zone and the second contact zone.
16. The loadbreak connector assembly of claim 15 , further including a floating contact moveable relative to the first and second contact zones.
17. The loadbreak connector assembly of claim 16 , wherein the electrical contact between the first contact zone and the second contact zone is caused by a moving the floating conductive contact that directly contacts the first and second contact zones.
18. The loadbreak connector assembly of claim 16 , wherein the moving of the floating conductive contact is caused by moving of the conductor in the connector assembly.
