　　 How to choose fuses for new energy products

　　Rated current: Firstly, it is very important to understand the rated current required for the product. The rated current should match the design and circuit requirements of the product itself. The rated current of the fuse should be slightly higher than the maximum operating current of the product to ensure the effectiveness of overload protection.

　　Freeze voltage: Determine the voltage range used by the product, and consider its freeze voltage when selecting fuses. The freeze voltage of the fuse should be able to adapt to the highest voltage used by the product to prevent the fuse from breaking down when the voltage is too high.

　　Melting characteristic: The melting characteristic of a fuse refers to its response speed in the event of overload or short circuit. Different application scenarios may require different types of fuse speeds. Some applications may require fast melting fuses to ensure timely circuit disconnection, while others may require fuses with delayed or slow melting characteristics.

　　Temperature coefficient: Considering the temperature range and changes in the application environment, choose fuses with appropriate temperature coefficients. The temperature coefficient determines the variation of the resistance value of the fuse during temperature changes, ensuring the reliable performance of the fuse at different temperatures.

　　Meaning and Interpretation of Current Fuse Markings　　The markings on a current fuse carry important information that is crucial for proper selection, installation, and use in electrical circuits. Understanding these markings is essential for ensuring the safe and efficient operation of the fuse and the overall electrical system.　　Voltage Rating:　　One of the common markings on a current fuse is the voltage rating. This indicates the maximum voltage that the fuse can safely handle in a circuit. For example, a fuse marked with a voltage rating of 250V means that it should not be used in a circuit where the voltage exceeds this value. If a fuse is subjected to a voltage higher than its rating, it may break down or fail to operate properly, potentially leading to a short circuit or other electrical hazards. The voltage rating is based on the insulation and structural characteristics of the fuse. It ensures that the fuse can withstand the electrical stress imposed by the applied voltage wi

　　　　A general fuse consists of three parts: one is the melt part, which is the core of the fuse and plays a role in cutting off the current when blown. Fuses of the same type and specification should have the same material, geometric size, and resistance value as small and consistent as possible. It is important to have consistent fusing characteristics, and household fuses are commonly made of lead antimony alloy; The second is the electrode part, which usually has two important components that connect the melt to the circuit. It must have good conductivity and should not generate obvious installation contact resistance; The third part is the support part. The melt of the fuse is generally thin and soft. The function of the support is to fix the melt and make the three parts a rigid whole for easy installation and use. It must have good mechanical strength, insulation, heat resistance, and flame retardancy, and should not produce phenomena such as breakage, deformation, combustion, an

　　The development of fuses　　The development of fuses can be traced back to the late 19th century, and the earliest fuses were made of simple metal wires. With the advancement of electrical technology, the design and materials of fuses are constantly improving. The following are some important stages in the development of fuses:　　1. Early development: Early fuses were mainly made of lead antimony alloy, which had a low melting point and good conductivity. But due to the toxicity of lead, this type of fuse is gradually being phased out.　　2. Modern fuses: Modern fuses are mainly made of silver copper alloy, which not only has good conductivity and melting characteristics, but also is more environmentally friendly. In addition, the structure of fuses has become more complex and diverse to meet the needs of different application scenarios.　　3. Intelligent trend: With the development of electronic technology, intelligent fuses have begun to appear. This type of fuse can not only achieve over

　　Tubular fuse　　Tubular fuse is a common and important circuit protection component, which plays a crucial role in various electronic devices and circuit systems with its unique structure and reliable performance. It is like a loyal guardian, always guarding the safety of the circuit.　　The main component of a tubular fuse is a fuse, which is encapsulated in a glass or ceramic tube. Fuses are usually made of low melting point metal alloys such as lead, tin, antimony, etc. When the current in the circuit exceeds the rated current of the fuse, the fuse will melt due to overheating, thereby cutting off the circuit and preventing damage to the circuit and equipment caused by excessive current.　　Tubular fuses have multiple advantages. Firstly, it has a simple structure, low cost, and is easy to install and replace. Secondly, its melting characteristic is stable and reliable, which can quickly melt when the current is overloaded, protecting the safety of the circuit. In addition, the rated cu

　　What is the significance of the breaking ability of patch fuses in practical applications?　　The breaking ability of patch fuses is a safety indicator that is not related to their electrical performance, so it is often overlooked by manufacturers or users, and some people even do not know the technical indicators of fuses having breaking ability.　　As a safety component, a fuse is required to ensure the safety of the circuit and other components at all times. Therefore, the first step is to ensure that it is sufficiently safe in any situation, especially when there are no unsafe factors during the operation of the fuse, including continuous arcing, re conduction, combustion, splashing, and explosion. Breaking ability is an indicator that reflects the guarantee ability of a fuse.　　The parameter unit of breaking capacity is ampere, which means that the fuse can safely break the maximum current of the circuit. That is, as long as the overcurrent in the circuit does not exceed the breaking
