Abstract
The utility model relates to a junction box for verifying a checking device of an electric energy meter, and the box comprises a rectangular shell, and a terminal group which is installed at the lower end part of the front of the rectangular shell and formed by ten wiring terminals, wherein the ten wiring terminals has the same structures and are arranged horizontally and uniformly. The box also comprises ten cylinder-shaped plugs with the same structures, wherein the ten plugs are installed on the bottom surface of the rectangular shell and respectively in one-to-one connection with the ten wiring terminals via wires. When the junction box provided by the utility model verifies the checking device of the electric energy meter, a reference electric energy meter is fixed with an electric current wire and a voltage wire which are used for the terminal group of the junction box, and the cylinder-shaped plugs at the bottom of the junction box are directly plugged into a wiring base of a tested electric energy meter of the checking device, and then verification work can be directly carried out. In this way, work efficiency is greatly reduced, and work time is saved, and potential safety hazards are eliminated.
Description
Technical field
The utility model belongs to the calibrator for watt-hour meter technical field, particularly a kind of calibrating calibrator for watt-hour meter special junction box.
Background technology
When using at present classic method calibrating calibrator for watt-hour meter, the not equal reason in calibrator for watt-hour meter connection terminal specification, position due to different model, cause standard electric energy meter and verifying attachment wiring process very complicated, affect work efficiency, and have certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of calibrating calibrator for watt-hour meter special junction box is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of calibrating calibrator for watt-hour meter special junction box, comprise the rectangle housing, be arranged on rectangle housing positive bottom by ten same structure levels all the terminal group that consists of of the connection terminal of arrangement processed and be arranged on rectangle housing bottom surface respectively with ten connection terminals cylindric plug of ten same structures being connected of corresponding lead one by one.
And described ten the same structure levels all spacing of the connection terminal of arrangement processed are identical with the spacing of existing connection box of electric energy meter terminal, and structure is identical with the structure of existing connection box of electric energy meter terminal.
And the jack of distance, length and the diameter between the cylindric plug of described ten same structures and the tested connection box of electric energy meter pedestal of existing calibrator for watt-hour meter is complementary.
Advantage of the present utility model and good effect are
When carrying out the calibrating of calibrator for watt-hour meter, standard electric energy meter and junction box streamline, pressure-wire are fixed, the terminal box bottom adapter directly inserts the tested connection box of electric energy meter pedestal of calibrator for watt-hour meter, just can directly carry out calibration operation.Greatly improved work efficiency, saved working time, eliminated safe hidden trouble.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of calibrating calibrator for watt-hour meter special junction box, as shown in Fig. 1 or 2, comprise rectangle housing 1, be arranged on rectangle housing positive bottom by ten same structure levels all the terminal group 2 that consists of of the connection terminal of arrangement processed and be arranged on rectangle housing bottom surface respectively with ten connection terminals cylindric plug 3 of ten same structures being connected of corresponding lead one by one.
In concrete enforcement of the present utility model, described ten the same structure levels all spacing of the connection terminal of arrangement processed are identical with the spacing of existing connection box of electric energy meter terminal, structure is identical with the structure of existing connection box of electric energy meter terminal, and described ten connection terminals are respectively used to connect Ia+, Ua, Ia-, Ib+, Ub, Ib-, Ic+, Uc, Ic-and the Un terminal of electric energy meter from left to right.
In concrete enforcement of the present utility model, the jack of distance, length and the diameter between the cylindric plug of described ten same structures and the tested connection box of electric energy meter pedestal of existing calibrator for watt-hour meter is complementary.
Principle of work
Ia+, Ua, Ia-, Ib+, Ub, Ib-, Ic+, Uc, Ic-and the Un terminal of standard electric energy meter Ia+, Ua, Ia-, Ib+, Ub, Ib-, Ic+, Uc, Ic-and Un terminal and the utility model terminal box are connected and fixed, form an integral body.When examining and determine, directly the bottom of the utility model terminal box is inserted the tested connection box of electric energy meter pedestal of calibrator for watt-hour meter and can examine and determine.
