Abstract
The utility model relates to a mutual inductance three-phase four-wire electric energy meter, which consists of an electric energy meter body and a connection box inside which wire inlet and outlet terminals are arranged, wherein, the wire inlet and outlet terminals are electric conduction inserted pins that stretch below the connection box; the sections of the electric conduction inserted pins are rectangular, which are correspondingly arranged in a plat plane and arranged in a line at the same interval; the connection box is positioned at the bottom of the electric energy meter. Since the wire inlet and outlet terminals of the utility model are the electric conduction inserted pins, the electric energy meter is only needed to be inserted in a matched bayonet socket when connecting inlet and outlet circuits, thereby not only reducing time that manual connection takes, but also lowering probability of wrong connection caused by carelessness and avoiding exposure of lead wires to cause thieves not to be capable of juggling with the circuits.
Description
Technical field
The utility model relates to a kind of electric energy meter (or claiming watt-hour meter), is specifically related to a kind of mutual inductance type three-phase and four-line electric energy meter.
Background technology
Electric energy meter (or claiming watt-hour meter) is a kind of electric energy metrical that is mainly used in various buildings places such as industrial and mining enterprises device, can independently install, and also can be installed in the low-voltage complete power distribution equipment and use as the electric energy metrical cabinet.
Existing electric energy meter, no matter be machinery or electronic electric energy meter, the input terminal of its electric energy meter and outlet terminal are manual binding post, i.e. all must adopt traditional manual mode of connection during wiring.Just there are following two aspect deficiencies in this: 1, expose the electric energy meter end of incoming cables, and electricity filching person often can cause immeasurable loss to department of State Grid from the terminals direct power taking of juggling things; 2, when wiring, need the installation personnel manual wiring of terminal one by one, spend a large amount of time, labor intensive.
Summary of the invention
The utility model provides a kind of mutual inductance type three-phase and four-line electric energy meter, and the utility model cooperates with plug-in type electric energy meter socket and can solve problem and the conventional connection terminal that artificial wiring wastes time and energy lead is exposed by the problem of people's stealing.
For achieving the above object, the technical solution adopted in the utility model is: a kind of mutual inductance type three-phase and four-line electric energy meter, constitute by electric energy meter main body and terminal box, and be provided with the turnover line terminals in the terminal box, described turnover line terminals is to stretch out the conduction latch of terminal box.
Related content in the technique scheme is explained as follows:
1, in the technique scheme, described conduction latch is a straight line and arranges;
2, in the technique scheme, the xsect of described conduction latch is a rectangle;
3, in the technique scheme, described conduction latch is oppositely arranged with flat horizontal surface and with identical spacing arrangement;
4, in the technique scheme, described terminal box is positioned at the bottom of electric energy meter, and the conduction latch is stretched out downwards by terminal box.
The utility model design concept is: the turnover line terminals of electric energy meter is designed to conduct electricity bolt-type, directly it is plugged in during use to connect on the electric energy meter plug socket that matches and reaches the socket connection structure with this, electricity filching person can not be juggled things in the end of incoming cables of electric energy meter, improve anti-electricity-theft performance, on the other hand, wiring is also more convenient like this, saves labor.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the turnover line terminals of the utility model inlet wire is the conduction latch, thus when electric energy meter with avoided exposing of lead after the plug socket that matches is connected, electricity filching person can't be juggled things on the line.
2, because the turnover line terminals of the utility model inlet wire is the conduction latch, when connecting the turnover circuit, need only electric energy meter is plugged corresponding electric energy meter socket, so reduced the time that artificial wiring will spend, having reduced may be owing to the probability of the careless false wiring that takes place.
