QYW Series Multi-function Protector
The QYW series multi-function protector is a dedicated protective relay for fully sealed transformers, which can provide functions such as light gas protection, low oil level protection, heavy gas protection (pressure over limit protection), oil level display (oil level gauge), oil injection, oil replenishment, pressure release, remote temperature display and protection for transformers. It can greatly facilitate the power supply department to monitor the operation of fully sealed transformers and diagnose transformer faults. It is suitable for electrical equipment such as oil immersed transformers, oil immersed reactors, and power capacitors, especially for fully sealed transformers and box type substations.
