Multi-current-channel single-phase electronic electric energy meter seat structure

Abstract

The invention discloses a multi-current-channel single-phase electronic electric energy meter seat structure which comprises a bottom housing (1), more than two relays (5) and a mutual inductor. The multi-current-channel single-phase electronic electric energy meter seat structure is characterized in that the bottom housing (1) is provided with a front terminal seat (2), a back terminal seat (6) and a bearing area; the relay (5) and the mutual inductor are arranged in the bearing area; and furthermore the front terminal seat (2), the mutual inductor, the relay (5) and the back terminal seat (6) are arranged in one-to-one correspondence and are successively connected. According to the structure, through staggered arrangement of two adjacent mutual inductors, space is sufficiently saved, sothat on the condition that the volumes of traditional single-phase electronic electric energy meters are approximately same, a plurality of mutually independent metering channels are designed, therebylogically dividing one single-phase electronic electric energy meter to multiple sets, settling defects of large mounting requirement space and high application cost in existing technological conditions. The mutual inductor with a double-housing structure can greatly improve insulation capability and voltage resistance of the component, thereby realizing high safety and high reliability.

Description

technical field [0001] The invention relates to a component structure of an electric energy meter, in particular to a structural layout design of the internal current components of the electric energy meter. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. The traditional single-phase electronic energy meter has only one measurement channel, but for multiple measurement channels, the volume of the energy meter can only be enlarged to increase the measurement channel, so its installation requires a large space and the application cost is high. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a multi-current channel single-phase electronic electric energy meter base with small installation space and low a...
