Digital Temperature Controller, Enclosure Type , Accessories For Dry Type Transformer

 

1 Type and Classification of Function

TypeFunction

Type D
(Ordinary type)

Three-phase circular measurement; Three-phase circular display/maximum value display and mutual switching between two functions; Input disconnection and trouble self-check display and output; Auto start and stop of cooling fan and output; Over-temperature alarm display and output; Over-temperature tripping display and output; Display of manual/auto modes of fan, output and mutual switching; Digital compensation for value displayed in each channel; Function of "black box"; Timed start, stop and control function of fan; Detection of output status.
Type EThe same as Type D, with addition of 4~20mA analogue current output.
Type FThe same as Type D, with addition of RS485 serial communications function.
Type GThe same as Type D, with addition of one-way transformer room temperature measurement and control.
Type IThe same as Type D, with addition of one-way transformer core temperature measurement and alarm.
Type LThe same as Type D, with addition of protection and alarm function for lack of phase and failure of fan.
Type C

The same as Type D, with addition of interlock control of Pt100
and PTC on over-temp alarm and over-temp trip signal.

 
Note: Other special requirements for the temperature controller should be indicated when placing orders.

3 Parameter setting function
 
Prompting characters for parameters have the following implications:
Ob: target value for start/stop of fan
dF: backlash of target value for start/stop of fan
AH: target value for over-temperature tripping
AL: target value for over-temperature alarm
ObJ: target value for start/stop of transformer room fan
dFJ: backlash of target value for start/stop of fan in transformer room
AHJ: target value for over-temperature tripping in transformer room
ALJ: target value for transformer core over-temperature alarm
Hb: target value for start/stop of dehumidification heater
HdF: backlash of target value for start/stop of dehumidification heater
Starting temperature of fan > Ob+dF
Stopping temperature of fan < Ob-dF
Starting temperature of fan in transformer room> ObJ+dFJ
Stopping temperature of fan in transformer room < ObJ-dFJ
Starting temperature of dehumidification heater > Hb+HdF
Stopping temperature of dehumidification heater < Hb-HdF
 
Note:
① The backlash of other target values than those for cooling fan, transformer room fan and dehumidification heater is all approved to be 0.3℃ tacitly.
② The parameters shown above are all for reference and specific set value shall be subject to the delivery label.
