The fusing current of the fuse should be between the rated current of the teaching equipment and the high current, so as to ensure that the enterprise equipment can be managed and operated normally. Turn off when the power approaches high current in a timely manner. Rated current refers to the current that an electrical appliance operates at rated voltage, which refers to the large current that students are allowed to pass through for a long time under the development conditions of rated voltage management work under different temperatures of the reference environment, and the heating temperature does not exceed the allowable temperature for long-term heating of the enterprise. High current refers to a limit of current that can be sustained without affecting equipment safety. It is generally only allowed to occur for a short period of time, otherwise it may cause equipment damage.
The operating current of the motor can operate for a long time, usually at most about times the rated current. This is usually due to the calculation of the power generated by improper motor selection, which is a small design. However, the motor can continue to operate at a higher operating current than the rated power at this time.
Fuses are considered commonly used in their current fuse protection, such as a 30 ampere fuse where the fused current lead 30 is safe, meaning that when the current in the circuit can reach 30 amperes, the fuse will burn out. However, currently with the increase of load power. Therefore, it also indirectly affects the data reflecting the power and varying degrees of the enterprise. According to the 380V voltage squirrel cage motor, students can estimate that the rated working current of a 50KW motor is about 50A, and the rated control startup information system design current is 50 × 6=300A, the calculation capability model formula for selecting problem analysis fuses is Inf=Ie/(~)=300/2=150A.
