Explosion pressure relay series

Pressure /explosion pressure relay series

Its explosion pressure controlling sensitivity should be set lower than 25KPa±20%. That is, when the pressure inside transformer rises in gradient way, the product of response time of explosion pressure relay and pressure gradient should be lower than 25KPa.

When pressure-increasing speed is lower than 2±2KPa/sec, no-response of explosion pressure relay should go in line with relay's property. Pressure relay may be used to replace electric warming device used for low pressure increasing speed monitoring which causes little losses to avoid unnecessary economic losses happened under extra pressure increasing speed.
