Introduction

A transformer temperature controller is a vital device that ensures the optimal operation of a transformer by continuously monitoring and regulating its temperature. The controller helps maintain the longevity and efficiency of transformers in electricity distribution networks, industrial facilities, and substations.

Role of Transformer Temperature Controller

The primary function of a transformer temperature controller is to prevent overheating, which can cause the degradation of transformer insulation and lead to failures. By keeping temperatures within a safe range, these devices enhance the reliability and safety of the power supply systems.

Operational Principles

Transformer temperature controllers utilize sensors such as Resistance Temperature Detectors (RTDs) and thermocouples to measure the temperature of the transformer oil and winding. This data is processed to determine if cooling systems, such as fans or pumps, should be activated.

Specific Parameters

The effectiveness of a transformer temperature controller can be assessed by parameters including:

• Accuracy: Temperature controllers typically boast a measurement accuracy within ±1°C.
• Response Time: Controllers are designed to respond within 5 seconds to changes in temperature.
• Temperature Range: Common operational ranges are between -40°C to 200°C.
• Power Handling: Able to manage systems up to several hundred kilowatts.
• Alarm Systems: Includes audible and visual alarms when temperatures exceed preset thresholds.
