Embodiment Construction

[0007] An overcurrent protection system of the present invention includes a current detection module, a current display control module and an intelligent start-stop module, the current detection module is installed on the electrical equipment, and the current display control module is respectively connected with the current detection module and the intelligent start-stop module, The intelligent start-stop module is installed on the switch of the electrical equipment. The current display control module includes a current display unit and a current control unit. The current control unit controls the maximum current of the system. When the current displayed by the current display unit is higher than the maximum current, the current control unit controls the start-stop module to turn off the device switch.

[0008] Finally, it should be noted that: obviously, the above-mentioned embodiments are only examples for clearly illustrating the present application, rather than limiting the...

Abstract

The application discloses an overcurrent protection system, which includes a current detection module, a current display control module and an intelligent start-stop module. The current detection module is installed on the electrical equipment, and the current display control module is connected with the current detection module and The intelligent start-stop module is connected, and the intelligent start-stop module is installed on the electrical equipment switch. The invention can monitor the current of the equipment in real time, disconnect in time when the current is overcurrent, and prevent damage to the equipment.

Description

technical field [0001] The invention relates to a protection system, in particular to an overcurrent protection system. Background technique [0002] Overcurrent is the current exceeding the rated current. A loop current greater than the rated current carrying capacity of the loop conductor is an overcurrent. It includes overload current and short circuit current. Overload current: The electrical circuit is overloaded due to too many electrical equipment connected or overloaded equipment supplied (for example, the mechanical load of the connected motor is too large). Its current value is only a few times of the current carrying capacity of the circuit. The consequence is that the working temperature exceeds the allowable value, which accelerates the deterioration of the insulation and shortens the life. It does not directly cause disasters. Short-circuit current: When the circuit insulation is damaged due to various reasons (including overload), conductors with unequal po...
