Background technology
Current transformer and electric energy meter are the indispensable instruments that matches each other in the electric-power metering, and the induction current that current transformer provides secondary to use in power supply directly enters electronic counter by induction line.The lawless person is often taken place and is used illegal utensil and means in various places in recent years, on the secondary line of current transformer and voltameter scale, make an issue of, to reach the purpose of power stealing, cause metering inaccurate, the electricity charge are risen at double, and it not only makes the electricity charge of country run off in a large number, cause the power supply department heavy losses, also increase electrician and user's the electricity charge burden of abiding by the law simultaneously, and the energy saving policy of country can't be implemented, cause the waste of electric power energy.
Summary of the invention
To be that design is a kind of can restrain the lawless person and use illegal utensil and means to steal the multi-functional single-phase electronic electric energy meter of mutual inductor input type of electric power energy on secondary mutual inductance metering circuit the purpose of this utility model.
The utility model is realized as follows: the multi-functional single-phase electronic electric energy meter of described mutual inductor input type, comprise housing, the integrated controlled plate of electronics, the electronic counter summation current transformer, the integrated controlled plate of described electronics, the electronic counter summation current transformer all is packaged in the front in the housing, and be connected to each other by lead, it is characterized in that: in housing, be provided with the induction by current coil, the induction by current coil is a torus, on the induction by current coil, be provided with the circular metal plate that central authorities have aperture, two joints of induction by current coil link to each other with current transformer, housing is provided with outside line firewire binding post and outside line zero line binding post, also be provided with user's firewire binding post and user's zero line binding post, one lead passes the induction by current coil and links to each other with user's firewire binding post with the outside line firewire binding post respectively with aperture on the sheet metal, and another lead does not pass the induction by current coil and directly links to each other with user's earth terminal with the outside line earth terminal respectively.
Described induction by current coil is around in annular core by three insulated wire spiral shells arranged side by side and forms, and annular core is made by Sz type high permeability material.
Good effect of the present utility model is:
One, internal wiring is reasonable in design, adopts current electrons control, does not have the machinery wearing and tearing, and own loss is low, meets energy-conservation requirement.
Two, accurate measurement, reduction line loss can alleviate the demand charge burden, the conservation of power energy.
Three, unit architecture is simple, and use cost is lower.
Four, easy for installation, long service life.
Five, in the normal power supply time, illegal molecule can't also can't be stolen electric power energy advancing on the phase current metering circuit to steal electricity on the secondary measurement circuit.
