Which manufacturer is good for the temperature controller of dry-type transformers

Transformer temperature controller, as the name suggests, refers to the equipment and instruments used to measure the temperature of transformers. Whether it is a dry-type transformer or an oil immersed transformer, a temperature controller is required. The winding temperature of the transformer needs to be measured, which is a very important thing for the operation of the transformer.

The safe operation and service life of power transformers largely depend on the safety and reliability of the transformer windings. The temperature of the winding exceeding the insulation tolerance temperature causes insulation damage, which is one of the important reasons for the inability of the transformer to function properly.

Supply IB-S201 series new dry temperature controller, multifunctional temperature controller, communication function temperature controller, commonly used function temperature controller. This temperature controller adopts microcontroller technology and uses three platinum thermistors embedded in the three-phase winding of a dry-type transformer to detect and display the temperature rise of the transformer winding. It can automatically start and stop the cooling fan to force air cooling on the winding, avoiding or reducing faults caused by high temperature in the transformer. It can also control over temperature alarms and over temperature trip outputs to ensure that the transformer operates in a safe state, thereby extending the service life of the transformer.

Multifunctional Temperature Controller Communication Function Temperature Controller Common Function Temperature Controller

1. The instrument panel is mainly in white and black, with a simple and elegant appearance. The concise black display box highlights the temperature, making the temperature value clear at a glance, reflecting the bold innovation and meticulous design philosophy of Inno Corporation.

2. The innovative flip design adds basic functional codes and operating steps inside, making it easy for on-site personnel to perform basic instrument operations and settings without a user manual.

3. A user-friendly human-computer interaction interface, with the instrument power switch and fuse box designed at the front end of the instrument, facilitates user operation and maintenance. Adding flip design not only looks beautiful, but also prevents accidental operation of buttons.

4. The instrument wiring terminals are abundant and can meet the special requirements of most users. Common terminal definitions are standardized and clear.

5. Universal terminals are also part of the industry. Users can define universal terminals as their desired functional outputs according to their own needs, greatly facilitating on-site changes in requirements.

6. Our company's CPU modular design concept for temperature controllers is industry-specific. The power supply circuit of the CPU module adopts an independent 3.3V power supply system, which is independent of other control and power circuits, reducing the interference of other circuits on the CPU and greatly enhancing the anti-interference ability of the CPU module.
