说明及应用 Instructions and applications

BH-系列热保护器，广泛用于1.5马力以下的各类马达电机、照明灯具、逆变电焊机、开关电源、电热器具等电器设备，防止因过热过流而产生的非正常工作提供有效可靠的安全保护、报警装置。加强型外壳适用于塑封电机内置式安装，可承受3.5MPa的塑料成型工艺压力。

BH-B-K series thermal protectors ,effective reliable security protector and alarm devices,are widely used in various types 1.5 horsepower motors, lighting device,inverter welding machine,switch power,electric appliances and other electric equipment to prevent from over-current & over-heating caused by abnormal work status. Enforced types that can withstand pressure of 3.5MPa are fit for build-in-installation of plastic coated motor.

原理及结构 Principle and structure

BH系列热保护器是一种温度自动回复装置。当电流通过有阻抗的双金属元件，无需任何辅助机构，仅靠双金属片自身感温和电流效应，使双金属片发生状态中的快速变化，从而断开电路或接通电路，达到过流过热双重保护功能，解决了电流突然增大时，温度感应滞后的问题，该产品内阻小，无噪声，密封牢固，具有比通常保护器，更安全可靠的特点。

BH series that can protecte against over-current and over-temperature are sealed firmly,small internal resistance,no noise and reset automatically. When current through bimetal that are sensitive to temperature and current, the status of the bimetal will be changed by over-temperature or over-current to cut off circuit or switch on circuit. BH series are safer than normal protectors,as there is no temperature effect lag under condition of sudden big current.
