Three-phase plug-in type electric energy meter mounting seat and use method

Abstract

The invention relates to a three-phase plug-in type electric energy meter mounting seat and a use method. According to the technical schemes of the invention, the three-phase plug-in type electric energy meter mounting seat comprises a box body, a box cover and binding posts; the box body and the box cover are matched with each other; the two ends of the box body are respectively provided with bottom incoming line wiring ends and top outgoing line wiring ends; the bottom incoming line wiring ends are communicated with the top outgoing line wiring ends; and three-phase power source incoming line holes, zero-line incoming line holes and electric energy meter auxiliary power source wiring holes are arranged between the bottom incoming line wiring ends and the top outgoing line wiring ends in a communicated manner. The three-phase plug-in type electric energy meter mounting seat of the invention has the advantages of simple structure, convenient use, flexible plugging and wide application range. With the three-phase plug-in type electric energy meter mounting seat adopted, electric energy meter mounting and replacement time can be effectively shortened with the reliability of measurement ensured, and wrong wiring which is caused by the loss of terminal number tubes or inexistence of terminal number tubes can be avoided; and no wires exposed at the electric energy meter wiring ends, and therefore, low current conduction rate and serious heating phenomenon which are caused by the deformation of conductors after the screwing of screws can be avoided effectively.

Description

technical field [0001] The invention relates to an electric energy meter installation device, in particular to a three-phase plug-in type electric energy meter installation seat and a usage method. Background technique [0002] The electric energy meter is the "one stalk" of electric energy measurement. It undertakes the important task of power enterprise trade settlement and enterprise internal economic and technical index assessment. Residential users, enterprises, all intervals of substations and the high, medium and low voltage sides of the main transformer need to be installed. Meter. With the increase of electricity load every year, the number of electric energy meters increases year by year, which brings great pressure on the installation and rotation of electric energy meters. [0003] The traditional electric energy meter rotation adopts the manual wiring method, which requires metering personnel to fix the incoming and outgoing wires one by one in the wiring h...

Problems solved by technology

[0003] The traditional electric energy meter rotation adopts the manual wiring method, and the metering personnel need to fix the incoming and outgoing wires one by one in the wiring hole at the end of the electric energy meter with screws

This connection method has the following unreasonable aspects: (1) The exposed part of the wire is inserted into the wiring hole at the end of the meter and fixed with the screw at the end of the meter. The conductor will be deformed after the screw is tightened. It is difficult to ensure the contact area between the conductor and the wiring hole and the current conduction (2) During the rotation process of the electric energy meter, it is necessary to check the line terminal numbers one by one, and the terminal number tube may be lost or there is no terminal number tube, which greatly increases the probability of wrong wiring by the staff and consumes a lot of labor. , especially when the current wires of the electric energy meter are reversely connected, the circuit can operate correctly and the transformer circuit is normal, and the metering personnel cannot directly judge the wiring error problem, but it will lead to measurement errors; In this case, it is necessary to remove the incoming and outgoing wires of the electric energy meter before the rotation can be carried out, especially the three-phase electric energy meter has many incoming and outgoing wires, so the rotation and maintenance of the electric energy meter take a long time, and the disassembly and assembly are not flexible and convenient.

There are deficiencies in the traditional electric energy meter wiring method, which makes it difficult to ensure the contact area between the conductor and the wiring hole, the current conduction rate is low, and the contact is prone to heat, the rotation and maintenance time is long, the disassembly and assembly are not flexible and convenient, and it is easy to cause measurement errors
