The Transformer Digital Top-Oil Temperature Controller is an advanced device primarily made up of a mechanical part and a digital sensing unit. This innovative system features a sealed assembly consisting of elastic elements, sensing conduits, and temperature sensing components, all filled with a specialized temperature sensing medium. As the temperature changes, the volume of this medium adjusts accordingly. This change is transmitted via the sensing conduit to the elastic element, creating a corresponding displacement. The mechanism amplifies this displacement, allowing it to accurately indicate the measured temperature and drive a micro-switch that outputs a control signal to regulate the cooling system, effectively managing transformer temperatures.

This Transformer Digital Top-Oil Temperature Controller utilizes composite sensing technology to convert the Pt100 platinum resistance signal found within the temperature pack into an RS485 digital signal, which is then sent to the control room terminal. With the capacity to store up to 10,000 monitoring data points and operational status information, this controller also allows for data export. Its capabilities include remote data transmission, alarm outputs, control signals, and local indication functionalities for communication abnormalities and self-checking faults. It can simultaneously display and regulate the top oil temperature or winding temperature of the transformer.

Manufactured in China, this top-quality controller is a reliable solution offered by trusted suppliers and factories. Its advantages include electrical isolation for communication, easy installation, robust anti-interference capabilities, and remote configuration. These features enable effective remote online monitoring of power transformer oil temperatures, making it an essential tool for managing transformer operations efficiently.
