Abstract
The utility model relates to an electricity stealing preventive device. The technical scheme includes that the electricity stealing preventive device comprises a transformer and a mutual inductor, and the mutual inductor is directly sleeved on a transformer porcelain bushing and covers the same. The electricity stealing preventive device has the advantages that current output by the transformer directly enters the mutual inductor after the mutual inductor is directly sleeved on the transformer porcelain bushing, so that the electricity stealing preventive device can prevent electricity stealing people from stealing electricity.
Description
Technical field
The utility model relates to a kind of senser element, relates in particular to a kind of anti-electricity-theft device.
Background technology
Still have many lawless person's stealings now, its means mainly are in the wiring privately of instrument transformer front, and privately in the instrument transformer front connection, institute's power consumption just can not be measured, thereby reaches the stealing purpose.Therefore, a kind of device that can prevent effectively that the lawless person from carrying out wiring before instrument transformer of research is the effective way that prevents that effectively the stealing incident from taking place.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and a kind of technical scheme of anti-electricity-theft device is provided, and adopts this scheme can effectively prevent stealing, and it is simple in structure, the processing and manufacturing cost is low.
The utility model is realized by following technical measures: a kind of anti-electricity-theft device, and it comprises transformer and instrument transformer, described instrument transformer directly is sleeved on the porcelain shell for transformer and covers porcelain shell for transformer.The electric current that instrument transformer directly is enclosed within transformer output in back on the porcelain shell for transformer directly enters instrument transformer, makes electricity filching person not have opportunity here.
Concrete characteristics of the present utility model also have, and above-mentioned instrument transformer inside is directly guided on instrument transformer voltage terminal from copper pad.Electricity filching person can't be by implementing to destroy the purpose that power taking presses signal to carry out stealing like this.
The inner secondary lead of above-mentioned instrument transformer directly is connected with cable, and connector lug is positioned at instrument transformer inside.So do not establish electric current, voltage terminal and directly link to each other with cable and the inner secondary lead of instrument transformer, connector lug is in instrument transformer inside, and the cable ammeter that goes directly reaches anti-electricity-theft purpose;
Above-mentioned instrument transformer is provided with the protection box, and the secondary current terminal of instrument transformer and voltage terminal are positioned at protection box inside, and current terminal is connected with cable with voltage terminal, and the other end of cable passes the protection box and draws.By adopting the protection box, preventive means such as lead sealing can be locked or stamp to the protection box.
Above-mentioned transformer is provided with four instrument transformers, in the instrument transformer on A, B, the C three-phase high permeability magnetic core is arranged, the interior mutually no magnetic core of O, and signal is pressed in a power taking, not power taking stream signal.
Single, the processing and manufacturing cost is low, the construction is also simple, it can effectively prevent stealing.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1, transformer, 2, instrument transformer, 3, porcelain shell for transformer, 4, cable, 5, the protection box.
Embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by an embodiment.
A kind of anti-electricity-theft device, it comprises transformer 1 and instrument transformer 2, instrument transformer 2 directly is sleeved on the porcelain shell for transformer 3 and covers porcelain shell for transformer 3.Instrument transformer 2 inside are directly guided on instrument transformer voltage terminal from copper pad.
Two kinds of methods are adopted in the electric current of instrument transformer output, voltage terminal protection: one, the inner secondary lead of instrument transformer directly is connected with cable 4, and connector lug is positioned at instrument transformer inside.Two, instrument transformer is provided with the protection box, and the secondary current terminal of instrument transformer and voltage terminal are positioned at protection box inside, and current terminal is connected with cable 4 with voltage terminal, and the other end of cable 4 passes protection box 5 and draws.
Above-mentioned transformer is provided with four instrument transformers, in the instrument transformer on A, B, the C three-phase high permeability magnetic core is arranged, the interior mutually no magnetic core of O, and signal is pressed in a power taking, not power taking stream signal.
The utility model can pass through existing techniques in realizing without the technical characterictic of describing, and does not repeat them here.Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection range of the present utility model.
