What is a fuse clip? After reading it, I understand.blade fuse colours

　　　　1. What is a fuse clip?　　Fuse clips refer to clips for installing fuses, which can be divided into two types: current fuse clips and automotive fuse clips. The clips for car fuses are usually installed on the panel PCB board and can be directly inserted into the circuit board for welding. They are located among various components of the car. Due to the small overall volume of the car and the complex internal mechanical structure, we place the fuse in the clip, which can facilitate maintenance personnel to immediately find and quickly troubleshoot the fault situation. At the same time, the role of clips is mainly reflected in safety aspects.　　2. Why use a fuse clip?　　For those familiar with industrial production, friends are familiar with the function of fuse clips because fuses are very small electronic devices, and most people tend to overlook them during use. Especially in large equipment, the installation and maintenance of safety components such as fuses are relatively difficul

　　　　The fuses used in power circuits and high-power equipment not only have the three parts of a general fuse, but also have arc extinguishing devices. This type of fuse not only protects the circuit with a high working current, but also has a high voltage at both ends when the melt melts. Often, the melt has melted (melted) or even vaporized, but the current is not cut off, The reason is that at the moment of fusing, under the action of voltage and current, an arc pulling phenomenon occurs between the two electrodes of the fuse. This arc extinguishing device must have strong insulation and good thermal conductivity, and be negatively charged. Quartz sand is a commonly used arc extinguishing material.　　Fusing device　　In addition, some fuses have a blown indicator device, which is used to indicate that when the fuse is activated (blown), its appearance changes to a certain extent, making it easy for maintenance personnel to detect, such as emitting light, discoloring, and popping up sol

What is the principle and material of a fuse.mini blade fuse box

　　　　When current passes through a conductor, contact occurs and the conductor may generate heat because it has a certain resistance. And the calorific value is calculated according to this formula: Q=0.24I2RT.　　2. Among them, Q is a calorific value and 0.24 is a parameter. I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time flowing through the conductor. By using this formula, you can easily discover the simple principle of fuses.　　When the raw materials and appearance of the fuse manufacturing are clear, its resistance R is relatively clear (if its resistance temperature coefficient is not considered). When an electric current flows through it, it becomes hot, and over time, its calorific value also increases.　　4. The height of current and resistance determines the speed of thermal energy, while the structure and assembly of the fuse determine the speed of thermal energy loss. If the speed of thermal energy is lower than the speed of

Don't confuse these two important concepts when choosing a fuse.automotive fuse box

　　　　Is the melting value of a fuse important? In short, this is important.　　This melting value is to ensure that the heat generated through the fuse during a surge does not have enough time to transfer heat from the fuse to the external circuit. Once the current I and time t are measured, the hot melt value I2t can be easily calculated. After the fuse is blown, it will generate an arc before opening.　　For fuses, they can have the same rated voltage and current, as well as the same rated breaking capacity, in the same response time category (slow, medium, and fast). However, there are many options for hot melt values.　　Basically, the higher the hot melt value, the longer the fuse will blow, or the greater the surge that the fuse will withstand before it blows. This is different from the breaking capacity of a fuse, which refers to the greater current that the fuse can withstand at a specified voltage before breaking the circuit or generating an arc. If the glass tube of the fuse breaks,
