There will always be owners of cars confused about why the fuse always burns though they usually pay attention to the car. Don't worry, first find the real reasons and then resolve accordingly. Determining several conditions of fuse burnout 1. Confirm the battery has electricity but the vehicle cannot start; the fuse of the motor starting the car is very likely to burn out. It is necessary to note that when the vehicle is found to be unable to start, keep in mind not to fire continuously, the continuous spark will cause the battery to continue to discharge up to the embarrassing situation of no electricity. 2. While driving, the vehicle's tachometer displays normally but the speedometer shows zero, and the ABS alarm light turns on, which shows that the fuse corresponding to the ABS burnt out. Some irregular business transport vehicles will unplug the fuse managing the ABS, the purpose is to not increase the mileage, but this brings the very big hidden danger, the loss of ABS will make vehicles very dangerous under an emergency situation. Attentions in change of fuse 1. Replace the fuse with the same specification If with small current, the fuse will soon burn, if with large current, then the fuse is not easy to burn in the case of short-circuit, thus it is very easy to cause fire. You should look at the mark of Amp at the top of the fuse when disassembling. If the fuse is burnt out so much so that the ampere value is unrecognizable, we can also use its color to judge, international standards: 2A Gray, 3A Purple, 4A Pink, 5A Orange, 7.5A Brown, 10A Red, 15A Blue, 20A Yellow, 25A Colorless transparent, 30A Green, 40A Deep orange color. 2. Take the right seats There are a lot of fuses in the fuse box. The car has a lot of circuits available for the selectable equipments, so there are many empty positions in the fuse box accordingly, if the fuse is inserted in the vacancy, it will not play a role. You should carefully check the appliances marked in English on the fuse box before the installation. Thus the fuse can play the best and most critical role.

The LED is driven by constant current, with a forward voltage ranging from less than 2V to 4.5V, and is related to color and current. The old design relied on simple resistors to limit the LED drive current, but the LED circuit was designed to cause overheating of the LED drive based on the typical forward voltage drop specified by the manufacturer. This may occur when the forward voltage drop through the LED drops far below a typical stated value. In such events, an increase in voltage through the LED drive device may cause higher dissipation of the total power from the drive package, thereby adversely affecting performance or life. At present, most LED applications use power conversion and controller components to connect various power sources, such as AC wires, solar panels or batteries, to control the power dissipation of the LED drive. These interfaces are protected against any damage from over current and over temperature, and often adopt polymer positive temperature coefficients (self resettable fuse PPTC) devices with a resettable capability. It can be prevented from any damage due to electrical short circuit, circuit overload or user misoperation. The self resettable fuse PPTC can also be placed after the MOV. Many equipment manufacturers preferred a combination of protection circuits and self resettable fuse PPTC devices with upstream fault protection.

At 19:41 on April 20, 2017, Tianzhou - 1 Cargo Spaceship was launched successfully in Wenchang, China, and entered the pre-selected orbit. At 12:23 on April 22nd, Tianzhou - 1 Cargo Spaceship and Tiangong - 2 space laboratory completed automatic rendezvous and docking successfully. After the completion of the Shenzhou ten missions, China's manned space engineering entered the development stage of space laboratory. In the space laboratory stage, we will break through and verify the key technologies such as propellant filling technology and regenerative loop control technology, which will lay the foundation for the construction of the space station. On September 15, 2016, Tiangong - 2 space laboratory was launched successfully, and it would be used to further verify the space rendezvous and docking technology and a series of tests, which indicates that China entered the implementation stage of task of space laboratory. In order to support the astronaut long-term residence and space science experiments in the future space station, it is necessary to supply the goods by the cargo spaceship. All space fuses used in the above-mentioned spacecrafts are manufactured by Shanghai Songshan Electronics Co., Ltd., which is the only designated supplier of Chinese aerospace grade fuse, and actually supplied the fuses to Chinese aerospace and military industry for over half a century.
