The general classification and zoning of fuses are generally based on eight levels: protection method, application scope, volume size, rated current, final breaking capacity, external characteristics, melting rate, and standard. 1. Classification by protection method There are two types of fuse protection: overcurrent protection and overtemperature protection; The fuse used for overcurrent protection is the overcurrent protection fuse, and the fuse used for over temperature protection is the temperature fuse. Temperature fuses are also divided into low melting point alloy shapes, temperature sensor open shapes, memory alloy shapes, etc. Temperature fuses are used to protect appliances that are hot or prone to overheating. They respond to the rise in temperature of electrical appliances and do not easily pay attention to the size of electrical flow in the operation of power circuits. Their principle is different from the "overcurrent protection fuse". 2. Classification by applica
1. Unauthorized modification of vehicle lights Many car enthusiasts are fond of modifying high-power headlights or xenon lamps. However, if the vehicle's headlights exceed the original overall planned output power or have a large load, it is inevitable that the fuse will melt. Suggest that if there is insufficient technical expertise or no need to tamper with the modification of cars. 2. Modify a high-power speaker Some buyers want to have the actual effect of Auditory system, which may be modified. But when the output power and disorder of the speaker exceed the original overall plan, the fuse will also melt. 3. Rinse the engine hood with tap water Many people wash their cars in the wrong way. For example, in the summer, many people require a water gun to wash the engine hood when washing their cars, and using a high-pressure water gun with such a high pressure to clean the engine hood can also easily cause short circuit faults in the power circuit.
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
The raw materials of self restoring fuses are not prone to aging themselves. The aging condition of the self-healing fuse device is due to the close connection between the metal electrodes on both sides of the device and the raw materials of the self-healing fuse. By multiple actions, the resistance of the self restoring fuse will be higher than the original resistor. When the resistance value exceeds the main parameter R1max of the resistor after a large action, the fault indicates that the manufacturer cannot ensure that the machine equipment does not operate while maintaining the current IH. The raw materials of self restoring fuses are not prone to aging themselves. The aging condition of the self-healing fuse device is due to the close connection between the metal electrodes on both sides of the device and the raw materials of the self-healing fuse. The self recovery fuse has strict requirements for rolling process operation, ensuring that the performance of the self recovery
In this link, the components that can block the oscillating current are usually fuses, but the general fuses are only disposable. If self recovery fuses are used, then the instruments in this type of circuit can be used for Test effort. And this type of function can be guaranteed not only by self recovery fuses, but also by some temperature sensors. However, these electronic components are far from fast in terms of reflection time compared to self recovery fuses. Therefore, for circuits with high-precision instruments, if some temperature sensors are applied, the oscillating current can burn out the instrument before the resistor blocks the power circuit. The function of a self restoring fuse is to provide overcurrent protection in the power circuit. A circuit with a high-precision instrument must have a fuse to maintain the safety of the high-precision instrument. However, if human factors are often used to remove and replace fuses during frequent use, it is not specific, which i
With the continuous upgrading and upgrading of many products, the current electronic products have increasingly high requirements for fuses. In order to protect the circuit safety of various products, fuses also need to be continuously improved. There are many types of fuses now, such as disposable fuses. Self restoring fuses, patches, inserts, and other fuses in different packaging can be applied to high-voltage and low-voltage working environments according to different types of fuses. Nowadays, fuses are becoming increasingly important in many electronic circuits. Insert fuses are common components in circuits, with a wide variety of unique functions, and are an important component of the normal operation of daily circuits. Insert fuses are also commonly used in automotive fuses, and automotive insert fuses are generally used for the following purposes. At various key points (or parts) of the car line, there are generally plug-in or tubular fuses, such as ceramic and special j
