JLS-6,10-phase oil-immersed outdoor high-voltage power metering box (hereinafter referred to as metering box) applies to the rated voltage of 10kV, rated frequency of 50-60Hz for power measurement with the three-phase AC network, by a combination of transformers and the meter box of two parts. JLS-6,10-type metering box is suitable for rural irrigation and drainage stations, township enterprises in a variety of enterprises, processing plants, small and medium factories, mines, transportation, public institutions as well as forestry, infrastructure, temporarily located on site high-voltage power transmission line power station metering. Small plant generates electricity metering or measurement network to send each runtime small power plant grid and countries. JLS-10 high-pressure metering box use of environmental conditions 1, altitude less than 1000m; 2, ambient temperature: up to + 40 ℃; daily average of less than 30 ℃; minimum -25 ℃; 3, the system grounding: neutral non-effectively grounded systems; 4, Air conditions: No heavy pollution. JLS-10 high-pressure metering box product main structure 1, the product of a combination consisting of transformers and the metering device box, combined transformer consists of two voltage transformers and two current transformers are assembled together. Metering box with D86 series three-phase meter and safety device, with a one-way metering Power Meter and a reactive power meter, two-way metering with two blocks and two Reactive Power Meter meter. 2, voltage transformer iron outer core type, with high-quality cold-rolled oriented silicon steel piled up in the columns of the multi-step shape, in a column equipped with primary and secondary coils. 3, the current transformer core is iron style, with high-quality cold-rolled oriented silicon steel is piled up in the legs of containing primary and secondary coils. 4, through the porcelain jacket conducting rod for the primary extraction voltage and current transformers for wiring. Voltage and current transformers are fixed on the pallet, the pallet by lifting the support bar on the cover, and immersed in transformer oil.
