Classification of fuses and fuses.where is the air conditioner fuse located

　　　　Fuses can be divided into high-voltage fuses and low-voltage fuses based on the voltage used. According to the protection objects, it can be divided into fuses for protecting transformers and general electrical equipment, fuses for protecting Voltage transformer, fuses for protecting power capacitors, fuses for protecting semiconductor elements, fuses for protecting motors and fuses for protecting household appliances. According to the structure, it can be divided into open type, semi closed type, tube type, and jet type fuses.　　The open type fuse has a simple structure, and the melt is completely exposed to the air. It is supported by porcelain columns and has no support, making it suitable for low-voltage outdoor use. When breaking the current, a large amount of sound and light is generated in the atmosphere.　　The melt of the semi enclosed fuse is installed on a porcelain frame and inserted into a porcelain box with metal sockets at both ends, suitable for low-voltage indoor use.

How to Design Chip Fuses.normally open vs normally closed

　　　　In electronic products, chip fuses have two functions: to protect users from harm and to protect circuits from damage. These functions benefit both device users and manufacturers. Over the past decade, the demand for electronic devices serving information technology, mobile, and consumer applications has sharply increased in the market. With this rapidly growing demand, the risk of unexpected situations in electronic devices has also increased, requiring the use of overcurrent protection devices such as chip fuses to avoid risks such as electrical overload.　　Before analyzing the electrical characteristics of various chip fuses in the market, it is first necessary to understand the basic design principles behind each technology.　　Standard fuses may be based on metal wires placed inside sealed ceramic or glass tubes filled with air or sand, but chip fuses are based on completely different principles. Most chip fuses appear to be standard chip devices and are made of single or multi-l

Plug type fuse.motor blows fuse on startup

　　　　1. When operating at a normal operating current of 25 ℃, the current rating of the fuse should usually be reduced by 25% to avoid harmful blowing. Most traditional fuses use materials with lower melting temperatures. Therefore, this type of fuse is relatively sensitive to changes in ambient temperature. For example, a fuse with a current rating of 10A is usually not recommended to operate at an ambient temperature of 25 ℃ and a current greater than 7-5A.　　2. The voltage rating of the fuse must be equal to or greater than the effective circuit voltage. The general standard voltage rating series are 32V, 125V, 250V, and 600V.　　3. The resistance of a resistor fuse is not important in the entire circuit. Since the resistance of a fuse with an amperage less than 1 is only a few ohms, this problem should be considered when using a fuse in a low-voltage circuit. Most fuses are made of materials with a positive temperature coefficient, so there are two types of resistors: cold resistance a

air conditioner fuse replacement.Guidelines for selecting self restoring fuses and disposable fuses

　　　　How to choose between traditional disposable fuses and self restoring fuses, as there are significant differences between these two components? Next, we will provide a detailed introduction to the advantages of these two types of fuses, making it easier for everyone to better understand these two products and choose the fuse they need.　　Many designs such as computers, peripheral devices, and portable devices (such as smartphones, tablets, etc.) require the use of self recovery fuses because the self recovery function provided by self recovery fuses is more suitable for use. If ordinary disposable fuses are used, they need to be replaced every time the circuit is abnormal or overloaded, and replacing fuses for these products is very troublesome. Therefore, using self restoring fuses on these products can not only protect the product's service life, but also improve usage efficiency.　　The principle of self restoring fuses is to limit potentially harmful overload currents within a saf
