Abstract
The utility model relates to a user outdoor electricity-stealing-prevention current transformer device for an operated transformer. The user outdoor electricity-stealing-prevention current transformer device for the operated transformer can effectively solve the problems that during long-time operation of electric power, accidents of loss of voltage and even burning losses caused by poor contact of compression joint exist, and power metering and safety operation are severely affected. According to the technical scheme, the user outdoor electricity-stealing-prevention current transformer device for the operated transformer comprises a mutual inductor and a concentrator. Concentric threaded connection pieces are arranged on a shell of the mutual inductor, and the mutual inductor is connected with the concentrator through a cable. A fixed body cable joint is arranged on the concentrator, and a meter is connected with the outer end of the cable connector. The end, arranged in the concentrator, of the cable connector is connected with a cable of the transformer. The concentrator is fixed on a shell of the transformer through a fixed body. The mutual inductor is arranged on a conducting rod of the transformer through the threaded connection pieces. The user outdoor electricity-stealing-prevention current transformer device for the operated transformer is simple in structure, novel, unique, convenient to install and use, capable of greatly improving power supply reliability and capable of reducing cable damage caused by electricity stealing.
Description
Technical field
The utility model relates to electrical equipment, particularly a kind of outdoor Anti-fraudulent use of electricity current transformer device for change.
Background technology
Development along with electric power, supply of electric power has related to huge numbers of families, become in people's life requisite, but the following stolen phenomenon of electricity consumption also happens occasionally, in order better to prevent the on-the-spot stealing of user, the numerous and confused the old and new's transformer device structure released according to different model of instrument transformer producer, develop all-insulated outdoor anti-stealing electric-combination current transformer.Transformer casing adopts outdoor advanced composite material (ACM) manufacture, and unique anti-electricity-theft structure can effectively prevent around more metering device stealing, is applicable to S series oil immersion power station area and becomes and the special-purpose metering become.This product has generally adopted middle compression joint type electricity-fetching method, and the problem of existence is in the product During Process of Long-term Operation, and the decompression that exists the crimping loose contact to cause, burning damage accident even, have a strong impact on electric-power metering and safe operation.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of the utility model just is to provide outdoor Anti-fraudulent use of electricity current transformer device for a kind of change, can effectively solve in the electric power During Process of Long-term Operation, the decompression that exists the crimping loose contact to cause, burning damage accident even, have a strong impact on electric-power metering and safe operation problem.
The technical solution of the utility model is, comprise instrument transformer and cable concentrator, the concentric sheet that is threaded is arranged on the housing of instrument transformer, instrument transformer is connected with cable concentrator through cable, the fixed body cable joint is arranged on cable concentrator, and cable joint outer termination gauge table, be placed in the cable of the termination transformer in cable concentrator, cable concentrator is fixed on transformer case through fixed body, and instrument transformer is contained on the conducting rod of transformer through the sheet that is threaded.
The utility model is simple in structure, novel unique, easy to install, greatly improves power supply reliability, reduces the line loss that stealing causes.
The accompanying drawing explanation
Fig. 1 is structural front view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
By Fig. 1, provided, the utility model comprises instrument transformer and cable concentrator, the concentric sheet 4 that is threaded is arranged on the housing of instrument transformer 3, instrument transformer 3 is connected with cable concentrator 7 through cable 6, fixed body cable joint 8 is arranged on cable concentrator, and cable joint outer termination gauge table, be placed in the cable of the termination transformer 1 in cable concentrator, cable concentrator is fixed on transformer case through fixed body 9, and instrument transformer is contained on the conducting rod 5 of transformer through the sheet that is threaded.
In order to guarantee result of use, described conducting rod comprises A phase conducting rod, B phase conducting rod, C phase conducting rod and zero phase conducting rod, the sheet 4 that is threaded has 3, be contained in respectively on the A phase conducting rod, B phase conducting rod, C phase conducting rod of transformer, cable concentrator 7 is connected with the zero phase conducting rod 2 of transformer through wire; Described cable concentrator is square or circular; Described transformer shell is together with the sheet lead sealing that is threaded.
By said structure, can be found out, the utility model is to adopt instrument transformer to be threaded connection sheet to be connected on the transformer guide rod, avoided traditional crimping power taking to cause decompression or loose contact to cause the heating accident, adopt concentrator box structure, installation dimension is not limited to the transformer model, be applicable to the various model transformers of different phase spacing M0, the housing of instrument transformer and the sheet lead-sealable actuation that is threaded are locked, after locked, instrument transformer 3 will be fixed on transformer and can not arbitrarily dismantle, can effectively prevent on-the-spot dismounting stealing, unified the causing in cable concentrator 7 of the every secondary armoured cable line of going up mutually 6 of transformer, neatly, use safety, be drawn out to external measurement meter by cable joint 8.
In a word, the utility model adopts the case type structure, and the power taking screw thread is arranged on housing, by special screw thread formula brace, inside and outside power taking screw thread and the transformer conducting bar of connecting, way to take power, avoided traditional crimping power taking to cause decompression or loose contact to cause the heating accident like this; Greatly improve power supply reliability, and reduce the line loss loss that stealing causes, good economic and social benefit is arranged.
