Plug-in energy meter

Abstract

The invention discloses a plug-in electric energy meter, which comprises the electric energy meter. The bottom of the electric energy meter has several connecting holes, and also includes a connecting seat, several metal sleeves and metal sockets. The metal sleeve includes a tube located in the lower half The seat and the cannula composed of several metal flaps located in the upper half, the cannula is provided with several wire passages in parallel along its axial direction, so as to form several spaced apart metal plates on the circumference of the end surface of the tube seat. The petal, at least one of the several wire slots is a through slot that runs through the socket and the intubation tube. The intubation tube of the tube is inserted into the connection hole of the electric energy meter, and the ratio of the diameter of the intubation tube to the diameter of the connection hole in the rebound state is 1.02~1.08:1. The invention greatly reduces the temperature rise, improves the stability and reliability of the electric energy meter, and increases the carrying current, which not only ensures the safety, but also expands the scope of application.

Description

technical field [0001] The invention relates to a plug-in electric energy meter, belonging to the technical field of electric power metering. Background technique [0002] In the prior art, most of the electric energy meters adopt the wiring mode, 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 install the electric energy me...

AI Technical Summary

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
