f certain technical means can be adopted during the installation of the combined transformer to prevent electric theft, it can reach the insulation technical indexes when the voltage and current transformer are poured together. The specific measures are as follows:
1. Considering the protection against power theft, the measurement unit adopts the method of one-time pouring, so that the secondary wiring of the transformer is not exposed to the outside, and the primary wiring is connected with insulated wires and insulated the primary terminal posts. The secondary connection between the metering box and the meter box is connected by cable with armor.
2. PT core, a combination transformer for preventing electric theft, adopts type C and is covered with secondary winding and primary winding on the core column. The secondary winding is uniformly wound on the insulation tube, and the outermost layer of the first and last two segments of the primary winding is provided with an electrostatic screen. The two windings are of multi-layer cylinder type. The primary windings are covered in the outside of the secondary windings, and there is insulation between the windings.
3. The primary coil and secondary coil of ct are of chain structure. The iron core is made of ultra-fine crystal alloy. The primary coil is made of high quality soft copper tape or glass silk enameled wire.
4. The pouring body is fixed on the base bracket with bolts. There are four screw holes on the bracket for users to install and use.
5, considering the field installation, adopt the split-type design, that is, according to the measurement method can be freely combined. The installation condition is simple, only need to install the lower pole, do not need double pole or pull wire;
The pouring body of the composite transformer for preventing electric theft is fixed on the base bracket with bolts. There are four screw holes on the bracket for users to install and use, and there are special grounding bolts on the bracket.
