SET Square TCO熱熔斷器使用扁鐵
一根易熔合金絲連接在熱熔斷器的兩個引腳之間, 被特殊的透明樹脂方形外殼覆蓋. 電流可以從一個引腳流向另一個引腳. 當熱熔斷器周圍的溫度升至其設定的工作溫度時, 其易熔合金絲熔化並收縮成球形, 並藉助表面張力和特殊樹脂附著在兩個銷釘的末端. 這樣, 電路被永久切斷.
Square shell type thermal fuse:
A fusible alloy wire is connected between the two pins of the thermal fuse, and the fusible alloy wire is coated with a special resin, so that the current can flow from one pin to another. When the temperature around the thermal fuse rises to its operating temperature, its fusible alloy melts and shrinks into a ball attached to the ends of the two pins under the action of surface tension and the help of special resin. 這樣, 電路被永久切斷.
The following items must be followed to ensure the normal operation of the thermal fuse:
我) Each thermal fuse has a rated current and voltage, a fusing temperature (轉鐵率), a use temperature (釷), and a maximum temperature (Tm值) and must be used within the specified parameters.
ii) When selecting the installation position of the fuse, be careful not to transfer stress to the fuse due to vibration in the finished product and displacement of other accessories.
iii) It should be installed in a place where the temperature will not rise above the maximum use temperature after the thermal fuse is blown.
iv) It cannot be used in machines where liquids or humidity are maintained above 95%.
v) The thermal fuse should be installed in a place that can only sense the heat source of the thermal fuse. When it is unavoidable to install a thermal barrier, 例如, when installing it on a heater, be careful not to connect it directly to prevent the hot wire from heating the temperature fuse.
vi) If the temperature fuse is connected in parallel to increase the current or if overcurrent or overvoltage is continuously passed, the internal contacts of the temperature fuse will be damaged, which will affect its normal operation. 所以, it cannot be used under the above conditions.
Although the temperature fuse is designed to be highly reliable, the abnormal situations that a single temperature fuse can cope with are limited after all. 另外, if the temperature fuse is damaged and cannot function normally due to human or unpredictable force majeure, the circuit will not be cut off in time when the machine is abnormal. 所以, when the machine is overheated, when the erroneous action directly affects the human body, when there is no circuit cutting device other than the fuse, and when high safety is required, use more than two temperature fuses with different fusing temperatures.
特徵: Radial and square thermal fuse, thermal cut-off (transparent shell)

筆記: The thermal fuse with an operating temperature Tf of 169℃ does not meet environmental protection requirements. If the customer needs, please contact the company’s sales department, thank you!
