Bwy Series Oil Temperature Indicator for Oil-Immersed Transforer

General:

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 Dimension: 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.

Specifications:

Weatherproof case to IP55 

Temperature range: 0~150 degree 

Indicating precision: 2.0 

Ambient temperature: -40 ~ +55 degree

Transformer winding temperature controller, continuously indicating temperature of transformer windings.

 

The complete indicator is comprised of two sections: 

1) BWR-04 temperature controller with one set-in electrical heating element and BL type current adapter. 

2) A digital displaying meter for remote control XMT (or XST)

 

Please tell us your detailed requirement and we will suggest suitable instrument.
