Abstract

The invention discloses an intelligent fuse. The intelligent fuse comprises a shell, lower three-phase line terminals, upper three-phase line terminals, a power switch, a display screen, an alarm light, a relay alarm speaker, and a control module, the lower three-phase line terminals are arranged at the lower part of the shell, the upper three-phase line terminals are arranged at the upper part of the shell, the power switch, the display screen, and the alarm light are arranged on the front surface of the shell, the power switch is arranged on the middle position of the shell, the relay alarm speaker is arranged at the right side of the shell, a control unit is fixedly arranged in the shell, and the lower three-phase line terminals of the fuse are connected with the intelligent control module. According to the intelligent fuse, the structure is simple, the usage is convenient, the intervention with a communication unit is prevented, the fuse and a power supply can be automatically separated, and the intelligent fuse can be widely applicable to various fusing circuits.

Description

technical field [0001] The invention belongs to the technical field of fuses and relates to an intelligent fuse. Background technique [0002] Fuses are a simple but effective way to protect electrical appliances. It mainly plays the role of short circuit protection in the circuit. The fuse is mainly composed of a melt and an insulating tube (insulation seat) for installing the melt. When in use, the principle of the fuse is to use the current to flow through the conductor to cause the conductor to heat up. After reaching the melting point of the conductor, the conductor melts, so the circuit is disconnected to protect the electrical appliances and the circuit from being burned out. It is an accumulation of heat, so overload protection can also be achieved, and the melt must be replaced once the melt burns out. However, there is no external display and alarm for the blown condition of the fuse in the current fuse. The communication unit circuit and the sub-communication ...
