　　Chip low-voltage fuse is a type of fuse, abbreviated as chip low-voltage fuse. The function of a low-voltage fuse is to provide short circuit protection in the circuit. Its advantages include high breaking capacity, strong reliability, small installation area, convenient maintenance, and low price. The disadvantage is that there are few protection methods and the recovery time of power supply is long. Baodian Tong's main chip fuse

　　How to Select Low Voltage Fuses with Chip Mounts

　　Commonly used low-voltage fuses include various types such as porcelain plug type, sealed tube type, spiral type, filler type, and so on. The ceramic plug type has poor arc extinguishing ability and is only suitable for use at the end of lines with small fault currents. Other types of fuses have arc extinguishing measures, with strong current breaking ability. The closed tube structure is simple, and the spiral type is safer when replacing the fuse tube. The filling material type has stronger current breaking ability.

　　Low voltage fuses are divided into plug-in, spiral, unfilled, and filled types according to their structural forms. According to the range of breaking current, it can be divided into: full range segmented capacity and partial range breaking capacity. According to the category of use, it can be divided into: general purpose and protection of electric motors.

　　When selecting patch low-voltage fuses, we need to determine the type of fuse based on the usage conditions. When selecting fuse specifications, we should first select the specification of the melt, then select the specification of the fuse based on the melt, and then have a good coordination between the protection characteristics of the fuse and the overload characteristics of the protected object.

The Protection Application of Self Recovery Fuses in Electric Toys.fast acting fuse bussmann

　　　　With the development of technology and social progress, people are paying more and more attention to the intellectual development of infants and young children. Various educational toys are springing up one after another, including electric and non electric ones, with thousands of types and varying quality requirements.　　When people purchase toys, they often pay more attention to their playable functions and neglect their safety. Many toy quality issues are only taken seriously when accidents occur, but it is too late and have already caused harm to people, some of which may last for a lifetime.　　In foreign countries and particularly developed countries, the safety of electronic toys is the most important. Regardless of certification, testing, research and development design, customer requirements, etc., the first consideration is safety, followed by the functions of toys, especially electric toys. Therefore, the safety protection of toys is the primary issue. In clause 3.6.2 of th

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,

what does a tv fuse look like.Factors affecting the lifespan of fuses and their evaluation

　　　　1. Factors that affect the lifespan of fuses:　　Working environment temperature:　　Excessive ambient temperature can damage the lifespan of the fuse. Delay type (slow melting type) fuses, such as tin ball type, begin to diffuse towards the metal wire when the temperature is about (150-170 ℃); The temperature at which the fusible metal wire of a quick fuse begins to undergo severe oxidation is approximately (175-225 ℃).　　Therefore, it is recommended that the delay type fuse fuse should not work above 150 ℃ for a long time, and the fast melting type fuse should not work above 175~225 ℃ for a long time.　　Pulse current:　　Continuous pulse impact can generate thermal cycling, leading to diffusion, oxidation, thermal stress, and even acceleration of the fuse. The fuse will gradually age with increasing pulse energy and frequency. Normally, it should be less than 20% to ensure that the fuse can withstand more than 100000 impacts.　　Other:　　For example, the length and cross-sectional area of t
