Photovoltaic and wind power box transformer intelligent temperature and humidity controller WSK-GF transformer temperature control oil temperature monitoring high precision temperature controller
summary:
Photovoltaic and wind power box transformer dedicated temperature controllers can measure the temperature of the transformer and the environmental temperature and humidity inside the box transformer. The digital display shows the temperature of the transformer and the environmental temperature and humidity inside the box transformer. This controller is specially designed and manufactured according to the JB/T7631-94 standard 'Resistance Thermometer for Transformers' to ensure the safe operation of the transformer as a new type of intelligent controller.
When the controller detects that the oil temperature is too high, it automatically starts the fan, triggers an alarm, and trips the circuit breaker. When the environmental temperature or humidity inside the transformer box is too high or when the environment is close to dew point, it automatically starts the environmental temperature and humidity control. The photovoltaic and wind power transformer box dedicated temperature controller uses NTC thermistors to measure the transformer's temperature and smart temperature and humidity sensors to measure the environmental temperature and humidity inside the transformer box. During the operation of the transformer, changes in oil temperature and environmental temperature and humidity are processed by the internal CPU and displayed simultaneously on the screen, showing the oil temperature of the transformer and the environmental temperature and humidity. At the same time, it completes various ventilation cooling, alarms, tripping, and environmental temperature and humidity control outputs.
The controller can simultaneously transmit temperature and humidity data, parameters, and various control alarm statuses to a remote computer via communication methods, forming a Distributed Control System (DCS). The controller can also be equipped with a 4-20mA transmitter output.
The main features are as follows:
1. Compact structure, aesthetically pleasing appearance, and easy installation.
2. Simultaneous display of transformer oil temperature and environmental humidity, allowing users to monitor temperature rise at any time and take appropriate measures.
3. Automatic fan start-up and manual fan start-stop functions.
4. Black box function, recording the temperature when the transformer loses power and the historical temperature during operation (optional).
5. Option for RS485 communication or transmitter output, enabling convenient remote signaling, remote measurement, and remote control functions (optional).
6. Comprehensive application of single-chip microcomputer technology, effectively identifying sensor open circuit and other fault signals, ensuring that the controller does not issue false over-temperature alarms or over-temperature tripping signals during power on/off.
7. New anti-interference design, with strong suppression capabilities for common mode and differential mode interference, meeting national standards for electromagnetic compatibility indicators.
