Description
Technical field
The present invention relates to electric energy meter technical field, be especially a kind of electric energy meter structure.
Background technology
Electric energy meter is a kind of instrument measuring electric energy.There is high-voltage circuit and low-voltage lines, it is therefore necessary to will on electric energy meter
High-voltage circuit and low-voltage lines are separated, to ensure that electric energy meter passes through electric voltage-withstand test.And by high-voltage circuit and low electricity
Line ball road separately can increase the volume of electric energy meter undoubtedly, and along with the development of technology, the miniaturization of electric energy meter is also trend of the times,
But the existence of high-voltage circuit and low-voltage lines will necessarily take bigger space, so that the scope of application of electric energy meter
More and more narrow.Therefore, for these reasons, it would be highly desirable to need one ensureing that electric energy meter volume can guarantee that again high electricity while little
Line ball road and the separate electric energy meter structure of low-voltage lines, to solve the problems referred to above.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and is ensureing that electric energy meter volume can guarantee that again high voltage transmission line while little
Road and the separate electric energy meter structure of low-voltage lines.
The technical scheme is that, it is provided that a kind of electric energy meter structure, including drain pan, terminal box, wiring board and case,
Described wiring board is provided with multiple electronic device；Described case is arranged on drain pan；Described terminal box is arranged on drain pan
Interior bottom；Described terminal box electrically connects with wiring board；Described wiring board is arranged between drain pan and case；Described
Case and wiring board are provided with one for by separate to high-voltage circuit and low-voltage lines electric pressure-resistance structure.
Described electric pressure-resistance structure includes that through hole and baffle plate, described baffle plate are inserted in through hole；Described through hole is arranged on
On wiring board, described baffle plate is arranged on case or drain pan.
Described through hole is elongated hole；It is provided with space between inward flange and the outward flange of baffle plate of described elongated hole.
Described baffle plate is embedded with sheet metal.
The interior bottom of described case is additionally provided with multiple housing for covering electronic device.
The inward flange of described housing and the outward flange of electronic device are provided with gap.
After using above structure, the present invention compared with prior art, has the advantage that
The case of electric energy meter structure of the present invention and wiring board are provided with one for by separate to high-voltage circuit and low-voltage lines
Electrically pressure-resistance structure, high-voltage circuit and low-voltage lines can be separated by this electric pressure-resistance structure so that thus high voltage transmission line
Road reduces with the distance of low-voltage lines, which reduces the volume of electric energy meter, to adapt to the trend toward miniaturization of electric energy meter, from
And make the scope of application of electric energy meter more and more wider.
As improvement, described through hole is elongated hole；It is provided with space between inward flange and the outward flange of baffle plate of described elongated hole.
The setting in this space effectively can must increase the most pressure performance, thus reduces high-voltage circuit and low-voltage lines further
Distance.
As improvement, described baffle plate is embedded with sheet metal.The setting of this sheet metal effectively can must increase the most pressure property
Can, thus reduce the distance of high-voltage circuit and low-voltage lines further.
