Fuse classification.fast blow or slow blow fuse for multimeter

　　　　According to the protection form, it can be divided into overcurrent protection and overheating protection. The fuse used for overcurrent protection is commonly referred to as a fuse (also known as a current limiting fuse). The fuse used for overheat protection is generally called "Thermal cutoff". Thermal cutoff can also be divided into low melting point alloy, temperature sensing trigger and memory alloy (Thermal cutoff is used to protect heating appliances or easily heating appliances from high temperature, such as hair dryer, electric iron, rice cooker, electric stove, transformer, motor, etc.; it responds to the rise in temperature of electrical appliances and does not care about the working current of the circuit. Its working principle is different from "current limiting fuse").　　According to the scope of use, it can be divided into: power fuse, machine tool fuse, electrical instrument fuse (electronic fuse), and automotive fuse.　　According to body integration, it can be divi

The fuse industry is poised for growth.automotive blade fuse manufacturers

　　　　With the continuous expansion of innovative models, the LED industry and market in Guangdong Province have entered a virtuous cycle. In the past two years, the price of LED street light products has decreased by 40%, gradually approaching traditional lighting fixtures.　　After customers apply LED lighting products, they can significantly save energy and recover the renovation cost as soon as 3 years. Through a series of demonstration projects, the various advantages of applying LED lighting products have become widely recognized by society, and the enthusiasm for their promotion has greatly increased in many places.　　The widespread use of LED lights makes the night scenery in Guangdong particularly beautiful, especially in the Guangzhou area. As is well known, the night scenery in Guangzhou is very beautiful. The application of LED lights in Guangdong ranges from the remote Deqing mountainous area to developed areas such as Shenzhen and Dongguan. 800000 LED street lights illuminate

plastic fuse board under stairs.Why does the resistance of patch fuses become large and constant?

　　　　The operating principle of a fuse is that an overcurrent causes the thermal balance on the melt to be disrupted. When the temperature of the melt rises to the melting point of the metal material, the middle part of the melt changes from solid to liquid. Due to the surface tension and gravity of the metal material suspended in the tube, the liquid part of the melt pulls away from both ends and sags downwards. The voltage caused arcing causes the melt temperature to continue to rise, further arcing and further distance pulling apart, Until the circuit is completely cut off. For SMD fuses, their operating principle is the same. However, due to different structural states, the surrounding of the metal melt is tightly surrounded by the polymer or ceramic materials of its substrate. Even the melted metal cannot contract towards both ends and can only rely on diffusion, infiltration, or absorption towards the surrounding materials. If the overcurrent disappears during this process (such a

What is the reason why the fuse keeps burning out?

　　　　1. Exceeding rated power: Fuses have a certain rated power, and when the power of electrical equipment exceeds the rated power of the fuse, it will burn out. The function of a fuse is to protect the circuit and prevent overload.　　2. When the current resistance value of the fuse exceeds the rated current value and burns out: When there is a short circuit or poor contact in the circuit, excessive current will be generated, causing the fuse to burn out. At this point, it is necessary to check whether the circuit is normal and whether the current withstand value of the fuse exceeds the rated current value.　　3. Use environment of fuses: The service life of fuses is affected by the ambient temperature. If the ambient temperature is too high, the service life of fuses will be shortened and they are prone to burning out.　　4. Material of fuses: Fuses made of different materials have different high temperature resistance performance. If the material of the fuse is not suitable, it is also ea

motor thermostat vs thermistor.Knowledge of overcurrent and overvoltage protectors

　　　　With the development of electronic technology and the upgrading of electronic products, the requirements for reliability and safety of power electronic products are increasing day by day. How many users are troubled by issues such as electrical leakage, burning of computer hosts, and explosion of mobile phones, and how many products have been delayed from being launched due to failure to pass safety testing. The diversification and complexity of problems have led to the rapid development of circuit protection components, and today's protection devices have developed into a diverse emerging field of electronic components.　　Faced with such a complex and diverse field, we have many questions. What is the development trend of protective devices? What parameters should application engineers choose appropriate protective devices based on?　　What factors should be considered in circuit design? How to handle failure analysis when encountering a faulty machine? In response to these issues, W
