Selection of fuse type.motorcycle fuse box waterproof

　　　　Select the type of fuse based on the electrical load characteristics in the circuit (slow melting or fast melting fuse). Fuses can be divided into slow fuse and fast fuse according to their different fusing characteristics. Fast melting fuses are commonly used in resistive circuits to protect components that are particularly sensitive to current fluctuations; Slow melting fuses are commonly used to quickly disconnect circuits when there is a fault with a large surge current when the circuit status changes.　　Finally, according to the sensitivity/capacitance circuit (such as the fan motor circuit), it can withstand the impact of surge pulses when switching on and off the machine, and the appropriate fuse type of structure is selected for the actual assembly position where the fuse wire appears. Priority should be given to fuses that occupy little space after installation.

　　　　The rated current of the melt is not equal to the rated current of the fuse. The rated current of the melt is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the melt and determined in conjunction with the main electrical appliance.　　The fuse is mainly composed of three parts: the melt, the shell, and the support, among which the melt is a key component that controls the fusing characteristics. The material, size, and shape of the melt determine the fusing characteristics. Melt materials are divided into two categories: low melting point and high melting point. Low melting point materials such as lead and lead alloys have a low melting point and are prone to melting. Due to their high electrical resistivity, the cross-sectional size of the melt produced is larger, and the metal vapor generated during melting is more. They are only suitable for fuses with low breaking capacity. High melting poin

　　　　Easy to install:　　The WH self resetting overcurrent protector has no polarity and can be connected in series to the circuit that needs protection. It is not only widely used, but also safe and reliable.　　Reuse:　　After cutting off the power and troubleshooting, it automatically returns to normal state without the need for manual replacement and can be reused.　　Improving quality:　　It can improve the quality of customer products, greatly reduce the natural damage rate of finished products, and greatly extend the service life of products.　　No reconnection:　　Under fault conditions, the faulty circuit will not be reconnected (other protective circuits, bimetallic plates, etc. will be repeatedly reconnected to expand the fault range).　　Add highlights:　　Due to the addition of high-tech elements, it can add new shining points to customer products, making vulnerable circuits no longer fragile.　　Reduce costs:　　Reduce the number of components, PCB area, and damage during operation compared to

How to judge the quality of ceramic tube fuses?

　　　　1. Introduce the function and classification of ceramic tube fuses, and emphasize the importance of judging their quality.　　Ceramic tube fuse is a common electronic component mainly used to protect circuits from damage caused by overload or short circuit faults. According to different rated currents and voltages, ceramic tube fuses can be divided into various models of different specifications. It is very important to judge the quality of ceramic tube fuses in use, which can ensure the normal operation and safe use of the circuit.　　2. Introduce how to judge the quality of ceramic tube fuses through visual inspection.　　Visual inspection is one of the most basic methods to determine the quality of ceramic tube fuses. Firstly, the fuse housing should be checked for any obvious damage or deformation. Secondly, it is necessary to check whether the contact between the two ends of the fuse is tight and whether there is oxidation or corrosion. Finally, the surface of the fuse should be che

very fast acting fuse.Why do fuses have high resistivity

　　　　Fuses, also known as current fuses, are defined as "fuse links" in the IEC127 standard. It mainly serves as overload protection. If the fuse is correctly placed in the circuit, the Shenzhen fuse will fuse and cut off the current when the current abnormally rises to a certain height and heat, protecting the safe operation of the circuit.　　More than a hundred years ago, the fuse invented by Edison was used to protect expensive incandescent lamps at that time. With the development of the times, the fuse protected electrical equipment from overheating and prevented serious damage caused by internal faults in electronic equipment.
