BWDK-S201D

Dry-type transformers need to be installed BWDKS201 thermostat, mainly because the thermostat has high-precision temperature monitoring capability and comprehensive protection functions, can provide reliable protection for the safe and stable operation of dry-type transformers, as follows:
  • Highly accurate temperature measurementBWDK-S201 thermostat usually adopts Pt100 platinum RTD as the temperature sensor, its measurement range can reach - 30℃-240℃, resolution can reach 0.1℃, accuracy ±1%, can real-time and accurately collect the temperature signal of the three-phase winding of the dry-type transformer, to provide reliable data support for the transformer temperature control and risk prediction.
  • Automatic thermal controlThis thermostat can be used to automatically adjust the temperature according to a set temperature threshold.Cooling FansStart-stop control. When the temperature of the winding is monitored to rise to a specific value, such as for dry-type transformers with class F insulation to reach 100 ℃, the thermostat will start the fan to strengthen the heat dissipation by itself, and after the temperature is lowered to the lower limit, the fan can be automatically shut down to ensure that the transformer is always in a reasonable temperature range.
  • Multi-fault protectionBWDK-S201 is equipped with a variety of protection mechanisms, it is generally preset with two temperature thresholds, for example, when the temperature reaches 130 ℃ will trigger the over-temperature alarm to prompt the operation and maintenance personnel to deal with, if the temperature continues to rise to 150 ℃ will trigger a tripping protection, to avoid the equipment due to the high temperature was destroyed, in addition, some models also have a phase protection to prevent the transformer from being damaged due to power failures.
  • Fault self-diagnosisThe thermostat supports the detection of sensor operation status, when there is a sensor disconnection, short-circuit and other abnormalities, it can issue a fault alarm, and with the help of the LED screen to display the fault code, so that the staff can quickly know where the problem is, and then quickly troubleshoot and solve the problem.
  • Compliance with industry standardsBWDK-S201 thermostat meets the requirements of JB/T7631-2005 and other relevant industry standards, the quality and performance of the product have been verified by the specification, and its installation on dry-type transformers can meet the regulatory requirements and technical specifications for the safety and reliability of electric power equipment during operation.
  • Intelligent Communication FunctionPart BWDK-S201 thermostat supports remote communication interface such as RS485 or Modbus, which can realize integration with SCADA system, DCS and so on, and it is convenient for users to monitor and manage the transformer remotely, and it meets the needs of industrial Internet of Things and smart grid development.
  • The price of installing a thermostat on a dry-type transformer consists mainly of the cost of the thermostat equipment and the cost of installation, as follows:

     

    • Cost of thermostat equipmentThe model and function of the thermostat will affect its price. Take the common BWDK-S201 thermostat as an example, according to the data of e-commerce platform, the BWDK-S201D thermostat of InnoTech is quoted by some merchants at RMB xxxx yuan.The BWDK-S201F thermostat is quoted at RMB xxxx yuan, while the BWDK-S201EFGI model is priced at about RMB xxxx yuan due to more complicated functions.
    • Installation costs: Installation costs cover expenses such as labor and auxiliary materials. For a simple replacement installation job where the thermostat itself is installed without complex debugging and wiring modifications, the labor cost may be around $xxxx in some parts of the country.
