　　1. When the melt melts, it is necessary to carefully analyze the reasons for the melting, which may include:

　　(1) Normal fusing due to short circuit fault or overload operation;

　　(2) If the melt is used for too long, it may break due to oxidation or high temperature during operation, resulting in changes in the characteristics of the melt;

　　(3) There is mechanical damage during the installation of the melt, which reduces its cross-sectional area and causes accidental disconnection during operation.

　　2. When replacing the melt, it is required to:

　　(1) Before installing a new melt, it is necessary to identify the cause of melt melting. If the cause of melting is not determined, do not replace the melt for trial delivery;

　　(2) When replacing a new melt, check whether the rated value of the melt matches the protected equipment;

　　(3) When replacing a new melt, it is necessary to check the internal burn condition of the fuse tube. If there are severe burns, the fuse tube should be replaced at the same time. When the porcelain fusion tube is damaged, it is not allowed to replace it with another material tube. When replacing the melt of a filler type fuse, attention should be paid to filling the filler.

Principles of explosion-proof fuses.radial circuit fuse

　　　　A general fuse is composed of three parts: an electrode, a support body, and a melt, while an explosion-proof fuse also has an arc extinguishing device. This type of fuse not only protects the circuit with a high fault 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 for this is that at the moment of melting, under the action of voltage and current, Arc pulling occurs between the two electrodes of the fuse. This arc extinguishing device must have strong insulation and good heat absorption, and be negatively charged. The arc extinguishing equipment has a unique arc extinguishing ability. The most important arc extinguishing agent among them includes a composition composed of SiO2 and chloride salts.　　Because when using fuses, especially miniature fuses, when the fault current is too high or the short circuit is disconnected, a powerful arc will be generated on them

Why are domestic fuses cheap?pptc resettable fuse datasheet

　　　　When choosing fuses, although they are of the same type, there are still differences. For example, the prices, quality, and parameters of fuses produced by domestic, foreign, and different fuse manufacturers may vary. Especially in terms of price, domestic fuses are cheaper than foreign ones. Why is this? There are also reasons from the fuse manufacturer　　Answer: At the beginning of design, foreign products have strict regulations from research and development, production, to delivery, basically taking into account many external factors. From the selection of raw materials, manufacturing processes, certification applications, and product pricing, customers have a clear understanding. After the product is completed, it can be tested and sold without any problems, and it will quickly gain customer recognition and trust, resulting in a naturally stable price.　　Domestic fuses are cheap　　The positioning of domestic products is to first imitate foreign products and produce them, first re

Description of Metal Materials for Self Recovering Fuses

　　　　Everyone knows about fuses, but the self recovering fuse (PPTC) in fuses may not be well understood.　　In fact, PPTC self-healing fuses, like the fuses we all know, play a role in limiting current and achieving circuit protection. Simply put, once the current in the circuit exceeds the specified current, it will cut off the current.　　In daily life, the application of fuses can be seen everywhere, such as in household appliances. But do you know what material it is made of?　　Self recovery fuse is an innovative type of fuse with more technical content and wider application range than ordinary fuses. It has the characteristic of being recoverable, so it must use easily melted metal materials to cut off the current in case of overcurrent and achieve protective effect. And this easily melted metal material is usually lead antimony alloy wire.　　Mainly using aluminum alloys with Mg as the main element (Mg based aluminum alloys have good corrosion resistance, strong thermal conductivity, an

Development Trend of PTC Chip Fuse Products.ceramic fuse color code

　　　　With the continuous development of the domestic economy and the rapid rise of the domestic electronics industry, the demand for PTC chip fuse products has increased from small to large, which has greatly promoted the development of PTC chip fuses. What are the trends in the development of PTC chip fuses in terms of quality, environment, labor costs, industry, etc?　　For the application of PTC patch fuse protection in circuits, using PTC has taken the lead and is in line with the trend. The statement that it will develop and grow is currently correct. In order to adapt to modern automatic production, the demand for SMD devices is increasing, and plug-in PTCs will be limited to the application of high voltage and high current products, so SMD devices are the development trend. The current specifications are developing towards both ends of the size range and towards smaller sizes. Continuously innovate by improving voltage levels.　　Without PTC, it violates the trend and will decline. D

Use and maintenance of fuses.solar panel fuse diagram

　　　　In low-voltage distribution systems, fuses are a type of electrical appliance that plays a safety protection role. Fuses are widely used for power grid protection and electrical equipment protection. When a short circuit fault or overload occurs in the power grid or electrical equipment, they can automatically cut off the circuit to avoid damage to electrical equipment and prevent accidents from spreading.　　A fuse is composed of an insulation base (or support component), contacts, melt, etc. The melt is the main working part of the fuse. The melt is equivalent to a special section of wire connected in series in a circuit. When a short circuit or overload occurs in the circuit, the current is too high, and the melt melts due to overheating, thereby cutting off the circuit. Melts are often made into filaments, grids, or sheets. Melt materials have the characteristics of relatively low melting point, stable characteristics, and easy melting. Generally, lead-tin alloy, silver plated co
