Summary
        JLSZV(W) - 6, 10, 35 series three-phase three wire outdoor dry type high-voltage combined transformer (with meter called power metering box) is applicable to 50Hz or 60Hz three-phase alternating current, 6kV, 10kV and 35kV Power Grid respectively, and is installed on the high-voltage side of the power transformer. The instrument box is equipped with three-phase three wire active, active and reactive meters, which are used to directly measure high-voltage lines Metering equipment for active and reactive electric energy. It plays an important role in preventing power stealing, saving energy and strengthening power supply management.
        JLSZV (W) - 6, 10, 35 series three-phase three wire outdoor, dry type, wide load combined transformer (with meter called metering phase), the product adopts imported outdoor epoxy resin casting insulation, full closed structure makes the product have anti violet line, anti-aging, rain proof, JLSZV-6, 10 series as one-piece structure, JLSZW-6, 10 series and JLSZWV-35 series as one-piece structure. The product can be used for single and double current ratio, and the high precision of 0.2S level ensures the accurate measurement under wide load. The double current ratio adopts the secondary tap structure.
        The product is composed of two parts: combined transformer and instrument box. The three-phase three wire combined transformer (two elements) consists of two single-phase voltage transformers (PT) and two current transformers (CT). Both Pt and CT are electromagnetic. Two Pt windings are connected with V / V to form three-phase measuring device. The primary windings of two cts are connected in series with phase A and phase C of power grid < br / >
