The anti-theft transformer

The anti-theft transformer is a guide rod penetrating type current transformer, which is characterized in that: the two secondary winding shell 1, with an iron core 2, voltage extraction piece 3, base 4 and the output terminals S1, S2, U, among them 1, housing a racket shape, the center has a through hole 5, hole 5 is arranged around the supporting tube 6, voltage extracting sheet 3 is placed on the support tube 6: two winding with a core of 2 circular, placed in the shell body 1, and the 7 sealed with insulating material, base 4 and a housing 1 buckle, the output terminals S1, S2, U are fixed on the base below 4. The output terminals S1, S2 are respectively connected with the two ends of the coil winding, the output terminal U and voltage extracting sheet 3 connection. The guide rod penetrating type current transformer is an ideal product for preventing electricity metering device of low pressure.

Characteristic
1 transformer and transformer directly installed on the guide rod, transformer center is filled with transformer guide rod, there couldn't be a wire through transformer center punch, eradicate theft.
The 2 voltage extracting sheet is provided with the locking structure (patents), screwed to the transformer on the guide rod, sparking discharge accident completely eliminate voltage extracting sheet between the transformer of the guide rod.
3 according to user needs, can be made into a three-phase four wire, three-phase three line one, one per phase separated forms.
