Description

Technical Field

[0001] The utility model belongs to the field of electric power meters, and in particular relates to a network multi-user electric meter. Background Art

[0002] The common specifications of the existing centralized network multi-user three-phase four-wire meters include B12 loop, C18 loop, D24, E36 loop, G42 loop, and each specification of the meter needs to have an independent shell frame and PCB board. The disadvantage is that it is very inflexible to use. If the customer needs to choose the 13-loop specification, only the 18-loop size frame can be provided instead. If the customer needs the 19-loop specification, only the D24-loop size frame can be provided instead, resulting in the vacancy of some outlet terminals and PCB boards, which in turn causes a waste of resources.
