Abstract
The invention relates to a novel intelligent electric energy meter box. The novel intelligent electric energy meter box comprises a box body, wherein the box body is internally provided with at least two electric energy meters, and the box body is respectively provided with a line inlet (5) and a line outlet (1); and the novel intelligent electric energy meter box is characterized in that the box body is respectively provided with a phase line common terminal (3) and a neutral line common terminal (2), phase line connecting ends of all the electric energy meters are electrically connected with the phase line common terminal (3) through guide lines, and neutral line connecting ends of all the electric energy meters are electrically connected with the phase line common terminal (2) through guide lines. The novel intelligent electric energy meter box disclosed by the invention has the beneficial effects that 1, the wiring accident repairing amount of the intelligent electric energy meter box can be reduced, and the wiring technology of the intelligent electric energy meter box can be regulated; 2, the phenomena of error and leakage in the intelligent electric energy meter box are beneficial to be checked by a worker, and thus the low-voltage line loss rate can be reduced; and 3, the unified use of the intelligent electric energy meter box and the reasonable current distribution of a client load can be realized.
Description
Technical field
The present invention relates to a kind of novel intelligent electric energy metering box.
Background technology
According to related specifications, at present for a single-phase intelligent electric energy meter, the correct wiring method is that (1,3 advances one-in-and-one-out; 2,4 go out).But when in an Intelligent electric energy meter box, many single-phase intelligent electric energy meters being installed, usually adopt the mode of connection of many intelligent electric energy meter series connections.Be the input terminal that total input-wire (power lead) is connected to first intelligent electric energy meter, then successively from the inlet wire of last intelligent electric energy meter and connect power lead to next intelligent electric energy meter.As shown in Figure 1, comprise 6 client's tables, namely client's table 1 is to client's table 6, and total current (I is total)=node 1 electric current=minute electric current I 1+ minute electric current I 2+ minute electric current I 3+ minute electric current I 4+ minute electric current I 5+ divides electric current I 6.
Find through actual the use, be easy to like this cause the wiring of front end intelligent electric energy meter to burn.Because the input terminal of last intelligent electric energy meter is the electric current summation by each intelligent electric energy meter, thus cause easily foremost intelligent electric energy meter tail connection terminal to damage even burn, thus user and power supply enterprise are all caused damage.
Summary of the invention
The purpose of this invention is to provide a kind of novel intelligent electric energy metering box, can realize intelligent low-pressure electric energy meter current reasonable distribution, solve user's low-voltage intelligent electric energy meter and frequently burn and wiring technical barrier lack of standardization.
A kind of novel intelligent electric energy metering box, comprise casing, at least two electric energy meters are installed in casing, and be respectively equipped with incoming line and line outlet at casing, its special feature is: wherein be separately installed with a public connection terminal of phase line and the public connection terminal of the neutral line at casing, the phase terminal of described all electric energy meters all is electrically connected by wire with the public connection terminal of this phase line, and the neutral line terminals of all electric energy meters also all are electrically connected by wire with the public connection terminal of this neutral line.
Wherein the public connection terminal of phase line and the public connection terminal of the neutral line are copper bar or aluminum strip.
Wherein on the public connection terminal of phase line and the public connection terminal of the neutral line, all have threaded hole, connection bolt is installed in threaded hole.
The invention has the beneficial effects as follows: the one, can reduce Intelligent electric energy meter box wiring construction amount, standard Intelligent electric energy meter box wiring technique; The 2nd, be conducive to the staff and in Intelligent electric energy meter box, find wrong, leak phenomenon, thereby reduce low voltage line loss rate; The 3rd, realized that the Intelligent electric energy meter box unification is used and the electric current reasonable distribution of client's load; The 4th, avoided the intelligent electric energy meter overload operation, prolonged wire and intelligent electric energy meter life-span.
Description of drawings
Accompanying drawing 1 is the structural representation of background technology of the present invention;
Accompanying drawing 2 is structural representation of the present invention.
Embodiment
As shown in Figure 1:
Total current (I is total)=node 1 electric current=minute electric current I 1+ minute electric current I 2+ minute electric current I 3+ minute electric current I 4+ minute electric current I 5+ divides electric current I 6;
Node 6 electric currents=minute electric current I 6.
Clearly, node 1 electric current is maximum, burns easily corresponding electric energy meter, and the present invention has then overcome this defective by public connection terminal.
As shown in Figure 2, the present invention is a kind of novel intelligent electric energy metering box, comprise casing, in casing, be equipped with to 6 electric energy meters, it is client's table 1, client's table 2, client's table 3, client's table 4, client's table 5 and client's table 6, and be respectively equipped with 1 incoming line 5 and 2 line outlets 1 at casing, and be separately installed with a public connection terminal 3 of phase line and the public connection terminal 2 of the neutral line at casing, the phase terminal of all electric energy meters all is electrically connected by wire with the public connection terminal of this phase line 3, and the neutral line terminals of all electric energy meters also all are electrically connected by wire with the public connection terminal of this neutral line 2.
As shown in Figure 2, the public connection terminal 3 of phase line and the public connection terminal 2 of the neutral line are banded copper bar or aluminum strip, clearly, the sectional area of two connection terminals should mate with the total current of passing through, and on the public connection terminal 3 of phase line and the public connection terminal 2 of the neutral line, all have threaded hole, connection bolt 4 is installed in threaded hole, thereby is convenient to wiring.
Claims (3)
