SYJ Series  Quick-Acting Oil Pressure Relay

Quick-acting oil pressure relay is a kind of pressure protection relay which
uses the speed of pressure change inside the oil tank as the measurement
signal. It can monitor the pressure inside the oil tank in real time and is used to protect the operation safety of electric power equipment. It is mainly used in oil- immersed power transformers, reactors and power capacitors and other power equipment. When the internal pressure of the tank is greater than 3±1kPa/s,
the quick-acting oil pressure relay can be operated, and the time of its action
response is shortened with the increase of the pressure gradient. The action
characteristics of this product can make the transformer and other power
equipment send electrical signal in time and cut off power supply when they
are in sudden malignant accident and the internal pressure of the tank is still in low pressure level, thus greatly reducing the failure losses of the transformer
and other power equipment.
