Description
Technical field
The utility model relates to a kind of current transformer, is specifically related to a kind of Anti-fraudulent use of electricity current transformer.
Background technology
In current low-voltage network at home, in order to prevent electricity filching behavior to take many Measures, installing low-voltage electricity larceny prevention complete at feeder ear transformer output is one of them.Existing Anti-fraudulent use of electricity current transformer comprises three current transformers, zero phase and a terminal box, this Anti-fraudulent use of electricity current transformer when mounted, as long as three of transformer low pressure guide rods are entangled by three current transformers respectively, although the Anti-fraudulent use of electricity current transformer of this structure has install advantage easily, but transformer is of a great variety on the market, between the low pressure guide rod of these transformers, spacing is different, thus the Anti-fraudulent use of electricity current transformer of this vibrational power flow exists the not strong defect of suitability.Although, market occurs the Anti-fraudulent use of electricity current transformer of spacing between some adjustable three current transformers, but its complex structure is comparatively complicated, and when regulating the spacing of current transformer, it is convenient not to operate, and have impact on the installation effectiveness of this Anti-fraudulent use of electricity current transformer.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides that a kind of structure is simple, suitability is strong, install Anti-fraudulent use of electricity current transformer easily.
For achieving the above object, the utility model adopts a kind of Anti-fraudulent use of electricity current transformer, comprise three current transformers and zero phase, three described current transformers are with a zero mutually transversely arranged setting and be connected by expansion corrugated pipe between any two, the side of zero described phase is provided with the cable outlet hole connected with expansion corrugated pipe, this cable outlet hole is provided with cable insertion, three described current transformers include instrument transformer housing and are arranged on the current coil in instrument transformer housing, three described current transformers and the bottom of zero phase are provided with cover plate, described each cover plate is fixedly connected on the lower surface of each instrument transformer housing and zero phase respectively by lead sealing screw.
The beneficial effects of the utility model are: this Anti-fraudulent use of electricity current transformer adopts expansion corrugated pipe to be chained together mutually with 1 by three current transformers, when installing this Anti-fraudulent use of electricity current transformer, as long as regulate the length of expansion corrugated pipe, get final product the spacing between three current transformers on this Anti-fraudulent use of electricity current transformer of quick adjustment, thus this Anti-fraudulent use of electricity current transformer has the advantage of adaptive various transformer, and this expansion corrugated pipe has good seal performance, the advantage that corrosion resistance is strong, and the cover plate of three current transformers and zero phase is provided with lead sealing screw, anti-electricity-theft effect can be played.
