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 fully enclosed transformer box specially designed to save equipment space and greatly reduce the workload of on-site installation. The new type of high voltage permanent magnet switch has the characteristics of small volume, high spirit sensitivity, reliable operation and long service life.


JLSZF-12-630 Outdoor integrated HV intelligent prepaid meter box

Jlszf-12-630 vacuum integrated high and low pressure prepaid control system is a new type of environmental protection and energy saving product independently developed and manufactured by our company. It is an integrated intelligent product suitable for metering and control switches for users of 50HZ frequency, 10KV lines or oil and gas fields, airports, railway lines, ports, electric power, factories and mines. The internal structure is composed of voltage and current, mutual inductor and zWJ-12 high-voltage vacuum permanent magnet switch independently developed by the company. It has anti-theft, anti-freezing and anti-high temperature properties. The voltage transformer USES V/V wiring and sets special winding to provide power for the closing and opening of high-voltage permanent magnet switch. Two current transformers are connected in series to phase A and Phase C respectively, and special windings are set for overcurrent protection at the same time. The product is light in weight, compact in structure, easy to install, simple in structure design and convenient in construction. The machine can be operated by remote control. The ZWJ high voltage permanent magnet switch has been appraised by The National high voltage testing Station (Shanghai Electric Transmission and Distribution Experimental Center Co., LTD.) to ensure qualified product quality.
