ANSI electrical modular meter for electricity meters
An electricity meter assembly includes a meter and a module assembly. The meter includes a meter cavity, at least one electrical component within the meter cavity, and a module compartment having a module cavity. The module compartment is within the meter cavity and the meter cavity is isolated from the module cavity. The module assembly includes at least one supplemental board configured to supplement the at least one electrical component. The module assembly is removably positioned within the module cavity such that the module assembly is field-removable, and wherein the module assembly is hot pluggable with the meter.
1. An electricity meter assembly comprising:
a meter comprising:
a housing comprising a side wall defining a perimeter of the housing, wherein the side wall at least partially defines a meter cavity of the housing and wherein the side wall defines a base slot;
at least one electrical component within the meter cavity; and
a module compartment secured and contained within the meter cavity, wherein the module compartment defines a module cavity comprising a module cavity opening, wherein the module compartment is contained within the housing such that:
the module compartment is within the meter cavity; and
the module cavity opening is aligned with the base slot such that the base slot provides access to the module cavity through the side wall; and
a module assembly comprising at least one supplemental board configured to supplement the at least one electrical component, wherein the module assembly is removably positioned within the module cavity such that the module assembly is at least partially positionable within the housing and is field-removable, and wherein the module assembly is hot pluggable with the meter.
2. The electricity meter assembly of claim 1 , wherein the meter is an ANSI meter.
3. The electricity meter assembly of claim 1 , wherein the at least one electrical component comprises at least one of a power supply board, a processing board, a communication board, a base metrology board, or a modular modem.
4. The electricity meter assembly of claim 1 , wherein the meter comprises a base assembly comprising the housing.
5. The electricity meter assembly of claim 4 , wherein the at least one electrical component comprises a plurality of electrical components within the meter cavity.
6. The electricity meter assembly of claim 4 , wherein the meter further comprises a cover assembly comprising a housing, and wherein the housing of the cover assembly forms a seal with the housing of the base assembly such that the meter cavity is sealed.
7. The electricity meter assembly of claim 6 , wherein the cover assembly comprises a gasket between the housing of the cover assembly and the housing of the base assembly such that the meter cavity is sealed.
8. The electricity meter assembly of claim 6 , wherein the housing of the cover assembly further comprises a cover slot aligned with the base slot and providing access through the housing of the cover assembly to the base slot.
9. The electricity meter assembly of claim 8 , wherein the module assembly comprises a module case defining a module case cavity, wherein the at least one supplemental board is removably positioned within the module case cavity, wherein the module case further comprises a case flange, and wherein the case flange is configured to abut portions of the housing of the cover assembly surrounding the cover slot such that the cover slot is sealed.
10. The electricity meter assembly of claim 1 , wherein the module compartment comprises a hot pluggable connector in the module compartment, and wherein the module assembly is configured to removably couple to the hot pluggable connector such that the module assembly is communicatively coupled with the meter.
11. The electricity meter assembly of claim 1 , wherein the supplemental board comprises a processor board.
12. The electricity meter assembly of claim 11 , wherein the processor board comprises at least one of a base metrology board or an advanced metrology board.
13. The electricity meter assembly of claim 1 , wherein the supplemental board comprises a power board.
14. The electricity meter assembly of claim 13 , wherein the power board comprises a DC power supply.
15. The electricity meter assembly of claim 1 , wherein the supplemental board comprises a communications board.
16. The electricity meter assembly of claim 1 , wherein the at least one supplemental board comprises a plurality of supplemental boards.
17. The electricity meter assembly of claim 1 , wherein the module assembly further comprises a module cover and a module case defining a module case cavity, wherein the supplemental board is within the module case cavity, and wherein the module cover is connected to the module case such that the supplemental board is sealed within the module case cavity.
18. The electricity meter assembly of claim 1 , wherein the meter cavity is physically isolated from the module cavity.
19. An electricity meter assembly comprising:
a meter comprising:
a housing defining a meter cavity;
at least one electrical component within the meter cavity; and
a module compartment secured within the meter cavity, wherein the module compartment defines a module cavity, and wherein the module compartment is secured within the meter cavity such that the module compartment is contained within the housing and the meter cavity is physically isolated from the module cavity; and
a module assembly comprising at least one supplemental board configured to supplement the at least one electrical component, wherein the module assembly is removably positioned within the module cavity such that the module assembly is at least partially positionable within the housing and is field-removable, and wherein the module assembly is hot pluggable with the meter.
