Thermal management for a meter collar adapter
A meter collar adapter may include an upper assembly having a housing to protect inner electrical components from adverse environmental conditions and a lower assembly to house electrical components, one or more conductors that pass through at least the lower assembly. Each conductor includes a first end to electrically interface with a meter socket and a second end to electrically interface with an electrical meter. The meter collar adapter further includes thermally conductive heat sinks to transfer heat from the lower assembly.
1 . A meter collar adapter, comprising:
an upper assembly that includes an outer housing; a lower assembly to house electrical components;
one or more conductors that pass through at least the lower assembly, each of the one or more conductors comprising:
a first end to electrically interface with a meter socket, and
a second end to electrically interface with an electrical meter; and
one or more thermally conductive heat sinks to transfer heat out of the lower assembly, the one or more thermally conductive heat sinks in thermal contact with at least one of the one or more conductors.
2 . The meter collar adapter of claim 1 , wherein the upper assembly includes a thermally conductive outer surface to dissipate heat from the interior of the meter collar adapter.
3 . The meter collar adapter of claim 1 , further comprising a non-electrically conducting thermal interface material disposed between the one or more heat sinks and portions of the one or more conductors passing through the lower assembly.
4 . The meter collar adapter of claim 3 , wherein the thermal interface material is compressed between the respective one or more conductors and the one or more heat sinks to transfer heat from the one or more conductors passing through the lower assembly to respective ones of the heat sinks.
5 . The meter collar adapter of claim 3 , wherein the thermal interface material electrically isolates the one or more conductors passing through the lower assembly from the heat sinks.
6 . The meter collar adapter of claim 1 , wherein the first end of the one or more conductors has dimensions in accordance with ANSI Cl2.10.
7 . The meter collar adapter of claim 1 , wherein the second end of the one or more conductors has dimensions in accordance with ANSI Cl2.7.
8 . The meter collar adapter of claim 1 , wherein the one or more conductors comprise laterally facing clamps to secure a corresponding conductor of the electrical meter therebetween.
9 . The meter collar adapter of claim 8 , wherein the laterally facing clamps increase current-carrying surface area of the conductor.
10 . The meter collar adapter of claim 8 , further comprising a spring disposed between upper portions of the laterally facing clamps to provide consistent tension between the clamps towards the second end of the corresponding conductor therebetween.
11 . The meter collar adapter of claim 1 , wherein the one or more conductors are comprised of a copper bus bar.
12 . The meter collar adapter of claim 8 , wherein the clamps are comprised of copper.
13 . The meter collar adapter of claim 8 , wherein the clamps are fastened together with the second end therebetween.
14 . The meter collar of claim 8 , wherein the clamps are riveted together with the second end of the conductor therebetween.
15 . A meter collar adapter, comprising:
an upper assembly comprising an outer housing;
a lower assembly to house electrical components; and
one or more conductors that pass through at least the lower assembly, each of the one or more conductors comprising:
a first end to electrically interface with a meter socket, and
a second end to electrically interface with an electrical meter, the second end comprising laterally facing clamps to secure the second end to the electrical meter.
16 . The meter collar adapter of claim 15 , further comprising a spring disposed between upper portions of the laterally facing clamps to provide consistent tension between the clamps towards a corresponding conductor of the electrical meter therebetween.
