Abstract
The utility model discloses an anti-theft electric transformer. The anti-theft electric transformer is applied to an electric power system and comprises a mutual inductor and a low-voltage guide rod, wherein the mutual inductor is arranged at the low-voltage side of the transformer, and the lower-voltage guide rod is led out of a mutual inductor core and used for being connected with a power transmission line. The mutual inductor and the lower-voltage guide rod are fixed through an anti-theft electric nut. The anti-theft electric nut is composed of an internal conductive layer and an external insulating layer. Two side wing plates are arranged on the two sides of the insulating layer. Wire sealing holes for sealing wires to penetrate through are formed in the side wing plates. The sealing wires wind the mutual inductor and then penetrate through the two wire sealing holes of the anti-theft electric nut one after another, and are sealed by lead seals. By the adoption of the anti-theft electric transformer, electricity stealing difficulties of criminals are increased, electricity can be effectively prevented from being stolen, the criminals must break the sealing wires or the lead seals to steal electricity, characteristics are obvious, and therefore a basis is provided for inspectors to find electricity stealing behaviors in time and obtain evidence.
Description
Technical field
The utility model relates to the potential device using in a kind of electric power system, specifically a kind of anti-theft electric transformer.
Background technology
Increase along with socioeconomic development and power consumption, in society, steal electric problem and become more and more outstanding, according to conservative estimation, the whole nation is every year because the stolen loss of electric energy is up to 20,000,000,000 yuan, this not only encroaches on power supply enterprise and the user's that abides by the law rights and interests, the development of puzzlement power supply enterprise, has also had a strong impact on national economic construction and social stability.At present, the current transformer of transformer is guide-bar penetrating, there is a voltage extracting sheet at the center of current transformer, this voltage extracting sheet is directly installed on the low pressure guide rod of transformer, the low pressure guide rod of transformer and outside instrument transformer are fixed by plain nut, the shortcoming of this structure is that nut is easily opened by people, thereby cause guide rod to rotate, cause inner lead short circuit or open circuit, also the technological means stealings such as instrument transformer that gone between wiring privately or changed little no-load voltage ratio by dismounting for lawless person on the other hand provide opportunity, even if there is stealing, inspector is also difficult to find, cause electric power system line loss serious.
Utility model content
The utility model technical issues that need to address are to provide a kind of anti-theft electric transformer, and it can prevent from stealing electricity effectively, and find in time to steal electric behavior and evidence obtaining provides foundation for inspector.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of anti-theft electric transformer, the instrument transformer that comprises step down side with in instrument transformer core, draw for being connected the low pressure guide rod of power transmission line, instrument transformer and low pressure guide rod are fixed by preventing fraudulent use of electricity nut, preventing fraudulent use of electricity nut consists of inner conductive layer and outside insulating barrier, in the endoporus of conductive layer, be provided with the screw thread mating with low pressure guide rod, conductive layer and insulating barrier are closely as one, on the outer surface of insulating barrier, be provided with two side wings, on side wing, be provided with the sealing hole for cross-under sealing wire, sealing wire is successively passed two sealing holes of preventing fraudulent use of electricity nut after being wound around instrument transformer, and with lead sealing, sealing wire is sealed.
Further improvement of the utility model is: described insulating barrier is hexagonal column, side wing be arranged in hexagon prism to angular direction.
Further improvement of the utility model is: the connected mode of described sealing wire is to penetrate in the sealing hole of a side wing of preventing fraudulent use of electricity nut, after winding instrument transformer, through after the sealing hole of same another side wing of preventing fraudulent use of electricity nut, two terminations of sealing wire is sealed with lead sealing.
Further improvement of the utility model is: the connected mode of described sealing wire is to penetrate a sealing hole that enters again another preventing fraudulent use of electricity nut above instrument transformer in a sealing hole of preventing fraudulent use of electricity nut above instrument transformer from first, finally gets back to after another sealing hole of first instrument transformer with lead sealing two terminations sealings of sealing wire.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model provides a kind of anti-theft electric transformer, and it can prevent from stealing electricity effectively, and finds in time to steal electric behavior and evidence obtaining provides foundation for inspector.After preventing fraudulent use of electricity nut screwing clamping is on low pressure guide rod, sealing wire is walked around to instrument transformer, and through the sealing hole of preventing fraudulent use of electricity nut, install again lead sealing additional, undesirable must destroy sealing wire and lead sealing before implementing to steal electricity, increased robber's electricity difficulty of undesirable, and feature is obvious, once there be the electrical phenomena of robber to be easy to inspected personnel, finds.
The outer surface of insulating barrier is hexagonal column, side wing be arranged in hexagon prism to angular direction, only having could smooth opening with special-purpose spanner, further increases and steals electric difficulty.
The utility model can seal single instrument transformer by sealing wire, also several instrument transformers can be sealed by a sealing wire.When any instrument transformer is disassembled, all can destroy lead sealing.
