雙金屬熱保護器

在電子設備和電器領域, 溫度控制對於確保設備正常運行和避免可能嘅損壞至關重要. 雙金屬熱保護器和熱熔斷器係兩種常見嘅溫度保護裝置，保護電子設備方面起著重要作用緊. 雖然佢哋嘅目標好相似, 它們的工作方式和使用地點存在一些關鍵差異.

Thermal protectors are a more complex device, usually made from a bimetallic sheet with a positive temperature coefficient (PTC). This means that as the temperature increases, its resistance also increases. When the temperature in the circuit exceeds the preset safe value, the resistance of the thermal protector will increase rapidly, causing the current to decrease, thereby reducing the temperature of the circuit. This self-regulating property allows thermal protectors to effectively prevent equipment from overheating and automatically shut down the circuit in the event of overheating. 因此, thermal protectors are widely used in various electronic equipment and appliances, such as motors, batteries, 變形金剛, 等.
