- Functional Features
- Temperature monitoring and displayThe temperature of the transformer winding can be monitored in real time, and the three-phase circuit display and the maximum value can be displayed, so that the operator clearly understands the temperature condition of the transformer winding in each phase.
- Fan controlAutomatic/manual start/stop function of the fan, automatic control according to the temperature of the winding.Cooling FansIt can also be manually operated to start and stop the fan, which is convenient for debugging and maintenance.
- Alarm and Trip Function: When the transformer temperature exceeds the set alarm threshold, an over-temperature alarm signal will be issued; when the temperature continues to rise above the trip threshold, an over-temperature trip can be realized to protect the transformer from high temperature damage.
- malfunction alarm: It can automatically detect the faults of itself and its sensors and other components, and send out an alarm signal as soon as a fault is found, so as to facilitate timely investigation and repair of the fault.
- Data logging and storageSome models have the "black box" function, which can record the transformer temperature and other related data, so that it is easy to query the historical data and analyze the transformer operation condition.
- Other Functions: such as fan timing excitation function, analog test function, digital compensation function, cabinet door opening alarm function, etc., which enhances the practicality and reliability of the thermostat.
- Model Classification
- IB-S201DThe basic model is equipped with three-phase circuit display/maximum value display, automatic/manual start/stop of fan, over-temperature alarm, over-temperature trip, fault alarm, "black box" function, fan timing excitation function, analog test function, digital compensation function, and cabinet door opening alarm function.
- IB-S201ED: On the basis of D type, three or four independent 4-20mA analog current outputs are added, which can be easily integrated with other systems to realize remote monitoring and data acquisition.
- IB-S201F: Based on the D model, RS485/232 serial communication function is added to transmit temperature and other data to a remote monitoring center for centralized management and monitoring.
- IB-S201G: On the basis of D-type, add a way to measure and control the ambient temperature of the machine room, and adjust the operation status of the transformer according to the ambient temperature of the machine room.
- IB-S201I: On the basis of the D-type, a transformer core temperature measurement and alarm is added, which can monitor the operating temperature of the transformer more comprehensively.
- Working Principle: The IB-S201 thermostat utilizes microcontroller technology to detect temperature changes in the transformer windings by means of a platinum RTD sensor embedded in the dry-type transformer windings. The sensor converts the temperature signal into an electrical signal and transmits it to the microcontroller of the temperature controller. The microcontroller processes, analyzes and judges the signals, and then controls the starting and stopping of the cooling fan, sends out alarm signals, and realizes trip protection and other functions according to preset parameters and logic to ensure that the transformer operates within a safe temperature range.
