Product Functions
◆Voltage Transformation: Steps down high primary system voltage to standardized, safe secondary levels for metering and protection equipment.
◆System Monitoring: Provides precise voltage signals for system monitoring, energy metering, and data acquisition.
◆Resonance Suppression: Its specific winding design prevents damaging ferromagnetic resonance, which can occur during system disturbances like single-pole switching.
◆Insulation & Grounding: The anti-resonance winding provides a dedicated path for zero-sequence currents, enhancing system stability during unbalanced conditions.
Applicable Environment
◇Location: Designed for installation in outdoor substations, switchyards, or along power distribution lines.
◇Climate: Built to withstand harsh environmental conditions, including rain, humidity, UV exposure, and wide temperature fluctuations.
◇Electrical System: Rated for use in 6kV or 10kV, 50/60Hz three-phase AC power distribution networks.
Product Highlights
◆Advanced Anti-Resonance Design: Unique three-phase, five-column core and specialized winding structure guarantee protection against system ferromagnetic resonance.
◆Robust Outdoor Construction: Vacuum-cast epoxy resin provides exceptional dielectric strength and mechanical protection for the coils, while silicone sealing ensures long-term waterproof and dustproof integrity.
◆High Reliability: The solid insulation system and durable materials offer a maintenance-free design with a long operational lifespan under outdoor conditions.
◆Accurate Performance: Delivers high-precision voltage transformation for reliable measurement and control signals.
◆Customizable: The JSZFW model can be tailored to specific technical parameters based on project requirements.
Installation Instructions
◇Safety First: Ensure the primary high-voltage circuit is de-energized, isolated, and grounded according to all local safety regulations before beginning installation.
◇Foundation & Mounting: Securely mount the transformer on a stable, level base or structure suitable for its weight and dimensions, as per the dimensional drawing.
◇Electrical Connections: Connect the primary terminals to overhead lines or busbars. Terminate secondary windings to measurement, protection, and metering panels, ensuring correct phase sequence and anti-resonance winding grounding.
◇Grounding: Establish a reliable and low-resistance connection from the transformer's designated grounding point to the station's main grounding grid.
◇Pre-commissioning Check: Before energization, perform a visual inspection, verify all electrical connections and grounding, and conduct recommended insulation resistance tests.
