What Thermal Challenges Do Dry-Type Transformers and MV Switchgear Face?

Dry-type transformers and medium-voltage switchgear operate under high electrical, ความร้อน, และความเครียดทางกล. Increasing power density, compact insulation structures, and continuous load variation make localized overheating a common risk. Winding hot-spots in dry-type transformers and contact or busbar heating in MV switchgear are often the primary causes of insulation aging, unexpected alarms, and forced shutdowns.

Why Is Accurate Hot-Spot Temperature Measurement Critical?

Temperature values measured away from the actual hot-spot do not represent the true thermal condition of power equipment. ในหม้อแปลงชนิดแห้ง, indirect measurement can mask winding temperature rise.
In MV switchgear, electromagnetic interference and limited installation space further reduce measurement reliability.Direct hot-spot temperature monitoring is essential for effective thermal protection and operational stability.

คืออะไร การตรวจสอบอุณหภูมิไฟเบอร์ออปติก?

Fiber optic temperature monitoring uses non-metallic sensors based on fluorescence decay technology to measure temperature directly at critical points. The sensing element is completely immune to electromagnetic interference and does not conduct electricity. This allows safe and stable temperature measurement inside high-voltage and high-current environments such as transformer windings and switchgear compartments.

Why Choose Fluorescent Fiber Optic Sensors?

Fluorescent fiber optic sensors provide absolute temperature measurement without electrical drift.Unlike electrical sensors, they are not affected by voltage stress, การปลดปล่อยบางส่วน, or electromagnetic fields.
Their long-term stability makes them suitable for continuous monitoring throughout the service life of the equipment.
