Product DescriptionSudden oil pressure relaySPR Transformers suddenly pressure relay is a type of protective relay that uses the rate of change of internal pressure in the oil tank as an electrical signal. It is used to safeguard the oil tank of equipment such as transformers, power capacitors, reactors, etc.SpecificationSPR Transformers suddenly pressure relay 1. High Sensitivity with Selective Activation: Remains inactive in low-pressure gradient zones within the tank while responding sensitively in high-pressure gradient areas to ensure tank safety. Sensitivity can be customized per user requirements.2. Wide Measuring Range: Can be installed at a vertical distance of 0–6 meters below the maximum oil level.3. Dual-Channel Quick-Action Output: Provides two independent rapid pressure signal outputs.4. Static Pressure Alarm (?80 mm Model): Equipped with a static pressure alarm function for enhanced monitoring.5. Robust and Compact Housing: Machined from high-strength aluminum alloy, ensuring leak resistance, structural integrity, small size, and an aesthetically refined appearance.6. On-Site Testing Enabled: Includes a user-friendly testing device for convenient field inspection.7. Superior Environmental Resistance: Excellent anti-corrosion, waterproof, and dustproof propertiesSPR Transformers Suddenly Pressure Relay Outline DFlange Dimension DrawingEnvironmental Conditions and Main ParametersParameterSpecificationAmbient Temperature-45°C to 70°CRelative Humidity≤95% (at 20℃)Contact CapacityAC220V 3A; DC220V 0.3AProtection LevelIP55ApplicationThe user types for the company's component product applications are:State Grid Southern Power Grid provincial companies, five major and six small power generation groups, industrial manufacturing and chemical enterprises and other special industries use electricity, as well as various power generation companies and new energy markets such as photovoltaic and wind power.
