바이메탈 열 보호기

전자 장비 및 가전 제품 분야, 온도 제어는 장비의 올바른 작동을 보장하고 손상 가능성을 방지하는 데 중요합니다.. 바이메탈 열 보호 장치와 열 퓨즈는 전자 장비를 보호하는 데 중요한 역할을 하는 두 가지 일반적인 온도 보호 장치입니다.. 목표가 비슷하더라도, 작동 방식과 사용 위치에 몇 가지 주요 차이점이 있습니다..

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. 그러므로, thermal protectors are widely used in various electronic equipment and appliances, such as motors, batteries, 변압기, 등.
