Özel Dahili Termal Sigorta bağlantısı ve kablosu

The Built thermal fuse is a thermal protector. Temperature Fuse link cable are mainly composed of melts and tubes, artı harici dolgu maddeleri. Kullanırken, connect the thermal fuse link cable in series with the protected circuit. Korunan devrenin akımı belirtilen değeri aştığında, ve belli bir süre sonra, eriyiğin kendisi tarafından üretilen eriyik eriyiği birleştirir, devreyi kırmak, böylece devreyi korur. Bir devreyi kırmak için metal iletkeni eriyik olarak kullanan elektrikli cihazlar devreye seri olarak bağlanır.. When an overload or short-circuit current passes through the melt, the melt itself will heat up and melt. Öyleyse, it has played a certain role in protecting the power system, various electrical equipment and household appliances. With anti-delay characteristic, when the overload current is small, the fusing time is long; When the overload current is large, the fusing time is short. Öyleyse, within a certain range of overload current until the current returns to normal, the thermal fuse Wire harness will not blow and can continue to be used. The Temperature Fuse link is mainly composed of a melt, a housing and a support. Among them, hot melt is the key element to control the fusing characteristics.

In the import and export tariffs, they are classified as 8535 veya 8536.

çalışma prensibi
A metal conductor is used as a melt in series in the circuit. When an overload or short-circuit current flows through the melt, it is fused because of its own heat, thereby breaking the circuit. Temperature Fuse link are simple in structure and easy to use. They are widely used as protection devices in power systems, various electrical equipment and household appliances.

Özellikler
The rated fuse current is not equal to the rated current of the fuse. The rated current of the melt is selected according to the load current of the protected equipment. The rated current of the fuse shall be greater than the rated current of the fuse, and shall be determined in cooperation with the main electrical appliance.

The Built Temperature Fuse link cable is mainly composed of a melt, a housing and a support. Among them, the melt is the key component to control the fusing characteristics. The material, size and shape of the melt determine the fusing characteristics. Melt materials are divided into two types, low melting points and high melting points. Low-melting materials such as lead and lead alloys have low melting points and are easy to melt. Because of its large resistivity, the cross-sectional size of the melt is large, and more metal vapor is generated during melting. Only for fuses with low breaking capacity. High melting point materials such as copper and silver have high melting points and are not easy to melt. Fakat, due to its low resistivity, it can be made smaller in cross-section size than a low melting point melt, and less metal vapor is generated during melting. Suitable for fuses with high breaking capacity. The shape of the melt is divided into two types: filament and ribbon. Changing the shape of the variable cross section can significantly change the fuse characteristics of the fuse.

Thermal fuses have anti-delay characteristics, that is, when the overload current is small, the fuse time is long; When the overload current is large, the fusing time is short. Öyleyse, within a certain overload current range, when the current returns to normal, the thermal fuse link cable will not blow and can continue to be used. Thermal fuse link cable have various different fuse characteristic curves, which can be adapted to the needs of different types of protection objects.

effect
Electrical components installed in a circuit to ensure safe operation of the circuit. When the circuit is faulty or abnormal, the current is constantly increasing, and the increased current may damage some important or valuable components in the circuit, or it may burn the circuit or even cause a fire. If the thermal fuse link cable is correctly installed in the circuit, the thermal fuse link will fuse itself to cut off the current when the current abnormally rises to a certain height and a certain time. So as to protect the safe operation of the circuit. Thermal cutoff cuts off the current, thereby protecting the safe operation of the circuit.

Inter-level cooperation
In order to prevent over-level fusing and expand the scope of the accident, there should be good coordination between the thermal fuse link of the upper and lower levels (ie, power supply trunks and branch lines). When selecting, the fuse rated current of the upper stage (power supply main line) thermal fuse link cable should be 1 to 2 stages larger than that of the lower stage (power supply branch line). Commonly used thermal fuses are tubular thermal fuses R1 series, Spiral thermal fuse RLl series, Packed closed thermal fuse link RT0 series and fast thermal fuse RSO, RS3 series, vesaire.
