Fuses are the simplest protective devices used to protect electrical equipment from overload and short-circuit currents; Choose different types of high-voltage fuses according to installation conditions and purposes, such as outdoor drop type and indoor type. For some special equipment high-voltage fuses, special series should be selected; The fuse we often refer to is a fuse type. Nowadays, the Energy crisis and environmental pollution problems are increasing day by day, and the haze weather in a large area of the country has sounded an alarm bell for people. In terms of environmental pollution, the impact of cars cannot be ignored. Developing efficient, energy-saving, and zero emission clean electric vehicles has become an inevitable trend in the development of the automotive industry both domestically and internationally. In order to improve the power performance and range of electric vehicles, the voltage of the power battery pack of electric vehicles is increasing, reaching several hundred volts, and the energy can reach tens or even hundreds of kilowatt hours. Once the power battery pack experiences a short circuit, it will instantly generate huge energy, posing a risk of explosion and fire, seriously endangering the safety of vehicles and passengers. To ensure the safety of on-board electrical appliances and passengers, and to prevent short circuits and overloads, fuses are generally used for protection.
