　　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.

Precautions for using fuses and fuses.charger fuse box diagram

　　　　Precautions for using fuses:　　1. The protective characteristics of the fuse should be adapted to the overload characteristics of the protected object. Considering the possible short-circuit current, a fuse with corresponding breaking capacity should be selected;　　2. The rated voltage of the fuse should adapt to the line voltage level, and the rated current of the fuse should be greater than or equal to the rated current of the melt;　　3. The rated current of each level of fuse melt in the circuit should be matched accordingly, and the rated current of the previous level of melt must be greater than the rated current of the next level of melt;　　4. The melt of the fuse should be matched according to the requirements, and it is not allowed to arbitrarily increase the melt or use other conductors to replace the melt.　　Inspection of fuses:　　1. Check whether the rated values of fuses and melts match the protected equipment;　　2. Check the appearance of the fuse for damage or deformation, a

Setting of fuse position.motorcycle blown fuse symptoms

　　　　To fully utilize the protective effect of a fuse in a circuit, the position of the fuse in the circuit should be considered when designing the circuit.　　The fuse can be blown in a timely manner to protect the circuit and switch;　　And the fuse cannot be blown in a timely manner, unable to protect the front-end circuit and switch. If a short circuit occurs at B, the fuse can only be blown in a timely manner, which can protect the circuit;　　As shown in the circuit diagram, when a short circuit occurs at point A, the switch will still burn out, while the fuse will not blow, meaning that the fuse in this circuit cannot protect the circuit and electrical components. So the circuit diagram is the most reasonable one for designing the position of the fuse in the circuit.　　Note: For the case where relays and fuses are integrated in the same electrical box, the fuse connection is not closely related (as the possibility of a short circuit occurring within the same electrical box is not high),

　　　　Why sometimes patch type fuses become highly resistant and we know that the operating principle of tubular fuses is: overcurrent causes the thermal balance on the melt to be disrupted, and when the melt temperature 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 drops downwards, The flashover caused by voltage causes the melt temperature to continue to rise, further flashover and further widening the distance until the circuit is completely cut off. For patch type 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 matrix. Even the melted metal cannot contract towards both ends and can only rely on diffusion, infiltration, or absorption towards the

　　　　1. The rated voltage of the selected fuse should be greater than the input voltage of the protected circuit.　　2. The rated current of UL specification fuses is determined under laboratory conditions and should be less than 75% of the nominal value during actual use.　　3. The rated current of IEC standard fuse tubes can be used at 90% or 100% of the nominal value in actual use.　　4. The working life of fuses varies under different operating temperatures. The higher the temperature, the shorter the working life of the fuse; When selecting fuses in practice, it is necessary to refer to the working environment temperature for selection　　5. The breaking capacity of a fuse tube is directly proportional to its volume and inversely proportional to the rated voltage.　　6. Under more than 100000 pulse impacts, the pulse I2T of the protection circuit should be less than 20% of the rated I2T of the fuse tube.

Characteristics of fuses and fuses.resettable pptc fuse

　　　　For the melt, its operating current and operating time characteristics are the ampere second characteristics of the fuse, also known as the inverse time delay characteristics, that is, when the overload current is small, the fusing time is long; When the overload current is high, the fuse time is short.　　Our understanding of the ampere second characteristic can be seen from Joule's law that Q=I2 * R * T. In a series circuit, the R value of the fuse remains basically unchanged, and the heat generated is proportional to the square of the current I and the heating time T. This means that when the current is high, the time required for the melt to fuse is shorter. When the current is low, the melting time required for the melt to melt is longer, and even if the rate of heat accumulation is less than the rate of heat diffusion, the temperature of the fuse will not rise to the melting point, and the fuse will not even blow. So, within a certain overload current range, when the current re
