The device consists of a combined transformer, a high voltage switch (permanent magnet structure), a measuring unit, an electrical energy acquisition terminal and a system management software.

The combined transformer unit consists of two current transformers and two voltage transformers to form the V/V-12 connection metering mode, which provides the ~220V power supply needed by the metering signal and the control unit.(The three components are connected by Y/Yn method, which is mainly suitable for three-phase unbalanced lines) The transformer body is made of outdoor epoxy resin in one time casting, which has good rainproof, ventilation and moisture-proof functions, and features of maintenance-free and high dynamic and thermal stability. The transformer combination and high voltage switch are installed together in a specially designed fully enclosed stainless steel box, which saves equipment space and greatly reduces the workload of on-site installation. The new type of high voltage permanent magnet switch has the characteristics of small size, high sensitivity, reliable operation and long service life.

The control unit (acquisition terminal) and the metering unit (electricity meter) are installed in the same control box, and the control box has an open-door monitoring system. The system management software is installed in the power management department. The acquisition terminal is directly connected with the permanent magnet switch by the anti-theft cable, which provides the on-off and on-off signal for the permanent magnet switch, and transmits the electrical energy and related information transmitted from the electricity meter to the system management software through GPRS/GSM channel, and responds to the system management software at the same time. The system management software not only has powerful information management functions, but also has the function of docking with the state grid 186 system. It is a necessary software for power system automation.

The device integrates acquisition, control, management and integration, and is an essential high-end technology product for the current power consumption management department to realize power consumption automation.


10KV outdoor inverted combination metering box

Jlszw2-10 inverted high-voltage meter box is suitable for active and reactive power measurement and prepaid control in lines with rated voltage of 10kV and rated frequency of 50Hz.

The current coil of the product combination transformer is placed on the top of the insulation pillar of 1000 sheets, which increases the creepage distance of the coil and improves the insulation strength of the product. The current transformer is poured externally with epoxy resin and placed upside down on the top of the stainless steel housing with the voltage transformer. The voltage transformer is placed inside the box under the current transformer. The box body is made of thickened stainless steel. The appearance is exquisite, the secondary output line is directly drawn from the inside of the box body, with anti-theft function.Suitable for urban and rural power grid transformation, residential communities, industrial and mining areas of the ideal replacement products.
