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

Main parameters of Thermal cutoff.thermal controller hardware

　　　　Thermal cutoff, also known as thermal fuse, is a new type of electrical overheating protection element. This component is usually installed in easily heated electrical appliances. In case of electrical failure and heating, when the temperature exceeds the abnormal temperature, the Thermal cutoff will automatically cut off the power supply to prevent electrical fire. In recent years, most of China's household electrical appliances with the main function of heating, such as Rice cooker, electric buckets, electric furnaces, etc., have been installed with Thermal cutoff. However, in case of internal failure of parts, Thermal cutoff can cut off the power supply in time to prevent further damage to the appliances and end the fire caused by this. Like the familiar fuse, the Thermal cutoff is usually only used as the power channel on the circuit. If it does not exceed the rated value, it will not open circuit and will not have any impact on the circuit. The circuit will only open when an e

The Importance of Fuses in Safe Sockets.battery terminal fuse replacement

　　　　A safety socket generally refers to a socket with a fuse and a power on indicator light. Usually, it has the characteristics of preventing leakage, overcurrent, high temperature, and lightning strikes, so safe sockets are also very popular in daily life. Today, I will tell you the importance of fuses in safe sockets　　In recent years, with the rapid development of science and technology and the widespread application of safety sockets, safety issues have also risen to a new level. In safety sockets, it is worth noting that when a fuse is blown, do not connect a wire to save time, as this will not function as a safety measure. It's best to go to a hardware store to purchase fuses or have a professional electrician repair them~!　　At the same time, the socket hole of the safety socket is covered by a layer of baffle, and you must use a pin to pass through the socket, which cannot be touched by hand.

Starting protection time of self recovery fuse.charger fuse in car

　　　　The starting time of protection has regularity, firstly, it is inversely proportional to the size of the components; Compared to the size of electronic devices, i.e. in the same series, such as the software fuse of the 250V series product, the smaller the current, the smaller the electronic device, which is twice the normal current. Due to its small size, fast heating, and faster startup protection time. Compared to the size of the fault current, it is easy to understand that the larger the fault current, the faster the component heats up and the faster the protection.　　When selecting a self recovery fuse, we all want to know whether the startup protection rate of the self recovery fuse is sufficient and immediate when a fault current occurs in the power circuit to protect the power circuit machine equipment.　　There are many models of self recovery fuses, and the starting protection rate varies among different models. And the time period required for starting protection under diffe

Classification of fuses

　　　　Fuse is a key component used for circuit protection, mainly to cut off the current when the circuit is overloaded or short circuited, in order to protect the safety of electrical equipment. According to different applications and characteristics, fuses can be divided into the following three categories:　　1. Plug in fuse: This type of fuse is usually used in cars and some household appliances. Its characteristics are easy installation and easy replacement. The plug-in fuse has a rated current value, and the selection needs to be matched according to the operating current of the circuit.　　2. Spiral fuse: This type of fuse is commonly found in old-fashioned electrical equipment, characterized by the fuse being wrapped around a ceramic core and then wrapped in a layer of glass or plastic shell. The replacement of spiral fuses is relatively complex, but they have strong resistance to high voltage and high current.　　3. Surface mount fuses: With the development of electronic technology, s
