　　　　Fuse, alias current fuse, is defined as "fuse link" in IEC127 standard and is a thermal Response element. The fuse is installed in a fuse box (fuse) or knife switch and connected in series in the circuit. The fuse invented by Edison over a hundred years ago was used to protect expensive incandescent lamps at that time.　　The fuse is mainly composed of three parts: the melt part, the electrode part, and the bracket part. Fuses are generally made of fusible metals such as lead, tin, lead-tin alloy, or zinc, with a very low melting point (approximately 200-300 ℃). Under normal circumstances, fuses can maintain reliable operation of the power grid, but in the event of overload or short circuit conditions, fuses with lower melting points are heated to the melting temperature by current and continue to be heated, causing some fuses to melt and vaporize, thereby cutting off the protected circuit and ensuring the safety of electrical appliances and connecting wires. Fuses are composed of po

Power System Fuses

　　　　Power systems are the backbone of modern society, supplying electricity to homes, businesses, and industries. Power system fuses play a fundamental role in maintaining the integrity and safety of these systems.　　Power system fuses are designed to protect the power grid at various levels. At the transmission level, where high - voltage electricity is carried over long distances, these fuses need to be able to handle extremely large currents. They are often installed in substations and are part of the protection scheme for transformers, transmission lines, and other key components. For example, a large - scale power transmission line may carry currents in the tens of thousands of amperes. The fuses in such a system must be able to detect and interrupt overcurrents quickly to prevent damage to the transmission infrastructure.　　In the distribution system, which delivers electricity to end - users, power system fuses also have a crucial role. They protect against faults in the distribut

Thermal cutoff NEC.best hair thermal protector

　　　　Although Thermal cutoff has high reliability in design, there are limits to the abnormal conditions that a single Thermal cutoff can cope with. In addition, due to man-made or unpredictable force majeure, the Thermal cutoff is damaged and cannot function normally, so the circuit cannot be cut off in time when the machine is abnormal. Therefore, when the machine is overheated, when the wrong action has a direct impact on the human body, when there is no circuit cut-off equipment except the fuse, and when high safety is required, more than two Thermal cutoff with different fusing temperatures should be used.　　The thin Thermal cutoff is specially developed for the over temperature protection of lithium ion batteries. Its working principle is the same as that of the second Thermal cutoff mentioned above. The circuit is connected with low melting point alloy, which is wrapped with flux resin, connected with metal guide plate and sealed with plastic material. When there is a short circui

Fuse appearance.resettable surface mount fuse

　　　　1. Filamentous. Early primitive fuses were directly locked with screws and used for various sizes of old-fashioned switches and sockets.　　2. Flaky (bare flake). More convenient to use than traditional filiform.　　3. Glass tube shaped. There are several different sizes, commonly found in electronic products.　　6.3 x 32 mm (diameter x length)　　5 x 20 mm　　4. Ceramic tubular. There are several different shapes and sizes to avoid glass bursting.　　5. Plastic sheet with metal sheet connector: automotive fuse.　　6. Surface mounted component (SMD) type.　　7. Cylindrical, plug-in type: directly soldered onto the circuit board, used internally in the product.

motorcycle blown fuse symptoms.The Price Trend and Future of Fuses

　　　　We know that in recent years, especially since 2016, domestic factories have increased their machinery and equipment on a large scale, especially the increase in square and SMD fuse automata, which has led to a continuous decline in these products in China. Especially, the price of square fuses has become transparent to the point where customers do not want to negotiate. There are actually several reasons for this situation:　　1: It is the continuous decline of the Chinese yuan, the constant hovering of the US dollar exchange rate, and the depreciation of the Chinese yuan　　2: There are too many homogeneous products, and in order to win more orders, we can only continuously compress profit margins, which is a common problem in the domestic manufacturing industry　　3: After the tax increase in the United States, many orders have been sharply reduced, especially the significant impact of large customer revenue, further forcing fuse factories to compress profit margins and dilute operati
