Product Description
The Spring-Loaded Transformer Pressure Relief Valve is a key safety protection device for oil-immersed transformers. It adopts a spring-loaded structure to achieve stable pressure control, rapid pressure relief and reliable sealing, effectively preventing damage to the transformer tank caused by abnormal internal overpressure and ensuring safe and stable operation of power equipment.
(Keywords: Spring-Loaded Transformer Pressure Relief Valve, stable pressure control, rapid pressure relief)
Product Details
This spring-loaded pressure relief valve is mainly installed on the oil tank of oil-immersed transformers and reactors. When internal pressure rises to the set value due to short circuit or fault, the valve opens quickly to release pressure. After the pressure returns to normal, the spring structure drives the valve to reset automatically and maintain tight sealing. It can effectively avoid oil leakage and external moisture intrusion, and meets the safety standards of power transmission and distribution projects.
Product Features
1. Spring-loaded stable structure: Ensures accurate opening and closing pressure with high operational stability.
2. Fast pressure relief response: Instantly relieves abnormal overpressure to protect transformer tank safety.
3. Automatic reset & sealing: Automatically closes after pressure relief with reliable sealing performance.
4. Long service life: Corrosion-resistant and aging-resistant materials, suitable for long-term outdoor operation.
5. Flexible configuration: Supports alarm contact customization to realize remote monitoring and alarm.
