Summary
        ZW (JLS) - 12 series pre paid combined transformer is composed of integral cast dry high-pressure measuring box and zw43f intelligent dividing switch, which is suitable for rated frequency 50Hz and rated voltage 10kV And below outdoor power system is used for power metering, which can provide users with 0.2S level products with various changes and double changes. The transformer is completely sealed by epoxy resin vacuum casting, so the aging problem is eliminated. The vacuum switch with zero sequence and protective current transformer is used in the dividing switch part, and the zero sequence, overcurrent and quick break protection are realized with the intelligent controller, which can automatically cut off the single-phase ground fault and automatically isolate the phase to phase short circuit fault. Ensure the power safety of non fault users. This product has FTU function to realize remote switch on and off: GPRS Remote control function (for details, please refer to "intelligent controller description" below).

Flexible and convenient operation of circuit breaker
Electric automatic energy storage, remote opening and closing. At the same time, it has the function of manual energy storage and manual opening and closing, which can be directly connected to the rated voltage output of the voltage transformer by the overhead line, transferred through the terminal box on the side of the circuit breaker, introduced to the controller by the connecting cable, and operated by the remote control of the controller. The operating mechanism adopts miniaturized spring operating mechanism, with low energy consumption of opening and closing: the mechanism adopts direct transmission mode, with few opening and closing components and high reliability. The operating mechanism is placed in the sealed circuit breaker mechanism box, which solves the problem of mechanism Corrosion and improves the reliability of the mechanism.

Performance overview of metering tank
This type of metering box is improved on the basis of similar products. It is suitable for measuring active and reactive electric energy in outdoor AC power system with rated frequency of 50Hz and rated voltage of 10kV. It is an ideal replacement of old oil immersed products.
The voltage transformer of this model is made of special outdoor epoxy resin vacuum casting with resistance to current and aging. Its appearance adopts umbrella skirt. Its surface has a large creepage distance. It is an ideal replacement product for the transformation of urban and rural power grids with rain, dust and corrosion resistance.
