JLS-10 inspection before acceptance and use of high-pressure metering box 1, visual inspection: the product well sealed, no broken porcelain pieces, factory documents (certificates of compliance, instructions) are complete. 2, with a 2500-volt megger to ground insulation resistance, its value is not less than 1000MΩ. (Air humidity less than 75%) Short-term frequency voltage test, the test voltage is 80% of factory test values. Products by long-term placement, prior to use, subject to 5.1,5.2,5.3 bar examination. 3, the installation should be checked and computational load match, the installation should be marked in line with the load value. When JLS-10 high-pressure metering box using methods and precautions 1, the product such as for electricity metering branch lines or for line loss assessment can be mounted on poles measuring box bracket. When used to measure the high side of the power transformer, the transformer can be installed on the same platform or on a pole. 2, the operation of the newly installed metering box discovery phase sequence is reversed, there will still forward watt-hour meter, reactive power meter reversal, the result of measurement error meter should measure any two high side box Root for change position, metering boxes to positive phase sequence, in order to ensure accurate measurement measuring box. 3. This product is used for two-phase power line to measure a power level, they should be engaged in the metering box B phase, and the remaining two phases in positive phase sequence of connections, preventing additional measurement error generated. You must use hanging climb on the tank when product lifting. 4, grounding screw terminals secondary transformer combination and b point on the tank should be grounded, so as to avoid accidents. JLS-10 high-pressure metering box maintenance and custody of running metering box should be checked regularly, if found signs of deterioration in oil or oil should be immediately replaced or supplemented with new oil filter. Metering tank before use properly kept in the warehouse, storage temperature of -25 ℃ to + 40 ℃, relative humidity less than 85%, ventilated, non-corrosive gases. To vigorously promote the 3C green grid construction, guide grid development to a more intelligent, efficient, reliable and green direction of change, September 4, Guangxi Power Grid's first 3C green substation - Nanning 110 kV substation is the completion and acceptance of Yuexiu, the upcoming "two sessions a "before it is put to use. According to reports, the so-called 3C green substation, is to use aspects of computer technology, communication technology, control technology, to reflect 3C function, its greatest feature is fully enclosed building, and the surrounding environment, "in harmony" with land, energy, materials , water-saving and environmental protection features. At the same time, the use of "3C" the technical upgrading of existing grids, which can effectively improve security, economy and energy saving level of the grid.
