易熔芯

易熔芯是一种精密设计的温度释放元件，用于工业机械和电气系统中。它由具有精确校准熔点的金属合金芯组成，封装在保护外壳内。当环境温度或运行温度超过预定阈值时，芯体熔化，触发机械或电气断开，以停止设备运行，从而防止热损坏、火灾隐患或系统故障。该组件在需要故障安全热保护的应用中至关重要。

易熔芯的工作原理是在特定温度下发生相变。在正常操作条件下，它保持固态并维持电路连通。当温度升高到其设计熔点（例如，由于过载、短路或环境因素）时，芯材发生固-液相变。这种熔化动作要么直接断开电气连接，要么激活二次机构（如弹簧释放）来断开电路，中断电力流动并停止机器以防止过热。

The fusible core operates on the principle of phase change at a specific temperature. Under normal operating conditions, it remains solid and maintains circuit continuity. When temperature rises to its designed melting point (e.g., due to overload, short circuit, or environmental factors), the core material undergoes a solid-to-liquid phase transition. This melting action either breaks an electrical connection directly or activates a secondary mechanism (like a spring release) to open the circuit, interrupting power flow and stopping the machine to prevent overheating.
