Pluggable electric energy measurement device

Abstract

The invention discloses a pluggable electric energy measurement device. The pluggable electric energy measurement device comprises an electric energy meter with the bottom provided with a plurality of connecting holes. The pluggable electric energy measurement device further comprises a connecting base, a plurality of metal sleeves and a metal socket. Each metal sleeve comprises a tube base on the lower half portion and an inserting tube which is located on the upper half portion and composed of a plurality of metal disc sheets, each inserting tube is provided with a plurality of wire through grooves in a parallel mode in the axial direction of each inserting tube so that the metal disc sheets which are arranged at intervals can be formed on the circumferential direction of the end face of each tube base, at least one of the metal disc sheets is a communicated wire groove capable of penetrating through each tube base and each inserting tube, and the end face of each inserting tube is a spherical crown surface. The center of the metal socket is provided with a wiring through hole into which an amphenol connector can be embedded, the inserting tubes of the metal sleeves are inserted into the connecting holes of the electric energy meter, and the ratio of the diameter of the inserting tubes under the bounce state to the diameter of the connecting holes ranges from 1.02 to 1.08:1. Temperature rise is greatly reduced, the stability and reliability of the electric energy meter are improved, the bearing current is improved, the safety is guaranteed, and the application range is expanded.

Description

technical field [0001] The invention relates to a plug-in electric energy metering device, which belongs to the technical field of electric power metering. Background technique [0002] In the prior art, most of the electric energy metering devices adopt the wiring method, and it is usually necessary to manually connect the incoming and outgoing lines to the terminals of the electric energy meter one by one. This method has the following disadvantages: (1) The temperature at the terminal connection rises, and there are problems of poor stability and reliability; (2) The terminal is difficult to withstand large currents, which limits its application range; (3) Even if the electric energy The meter is protected by a joint junction box, a terminal box and a seal, but it is still inevitable that some electrical connection lines are exposed, which not only poses a safety hazard, but also provides opportunities for electricity theft; (4) It is very inconvenient to install and inst...

Problems solved by technology

This method has the following disadvantages: (1) The temperature at the terminal connection rises, and there are problems of poor stability and reliability; (2) The terminal is difficult to withstand large currents, which limits its application range; (3) Even if the electric energy The meter is protected by a joint junction box, a terminal box and a seal, but it is still inevitable that some electrical connection lines are exposed, which not only poses a safety hazard, but also provides opportunities for electricity theft; (4) It is very inconvenient to install and install the electric energy meter on site. Checking the line connections one by one not only requires huge labor, but also easily leads to wrong wiring; (5) When a problem occurs and needs to be repaired, it is necessary to remove the incoming and outgoing lines before replacing the electric energy meter, thus causing the installation of electric energy meters. And the repair and replacement time is longer
