Model BWY—804 Transformer Thermoregulator is a new generation product derived from Model BWY—802/803 one in compliance with JB/T 6302-92 Standard of Pressare-type Thermoregulator For Transformer issued by The National Machinery Ministry.It is suitable for taking measurement and control of oil temperature in a medium-sized or Large-sized transformer.
The BWY—804 features following new points:
1.1 Wide scope of application
To meet the need of intelligentized control in an unattended transformer house, the BWS—804 can output following controlling signals
1.1.1 Pt100 platinum resistance signal；
1.1.2 4-20mA direct current signal；
1.1.3 RS232/RS485 communication interface。
1.2 Four sets of switch, which can be set within a whole span, are employed to respectively control over the transformer cooling system, overheating alarming and tripping, etc.
1.3 To satisfy different enquirements of customers, two selections of mounting dimension of the BWY—804 are offered when installation.
1.3.1 Mounting Dimension I：
It is the same mounting dimension as that of BWY—802/803, which is specified by JB/T 6302-92 standard.It is our recommendation that you adopt this one
1.3.2 Mounting DimensionⅡ：
It is the same mounting dimension as that of some imported meters.It is convenient for some customers who originally installed imported meters to replace with ours now.
