The invention discloses an automatic replacement device for a sealed type fuse of a distribution box, which comprises a distribution box body, the upper surface of the distribution box body is fixedly connected with a drive box, and the upper surface of the drive box is embedded with a Control panel, the back of the distribution box is provided with a discharge port, the back of the distribution box is fixedly connected with a receiving box, and the left and right sides of the distribution box are respectively provided with through holes. The automatic replacement device for the sealed fuse of the distribution box can control the lowering of the electric telescopic rod by setting the control panel. The damaged fuse inside the fuse mounting seat is moved from the discharge port to the inside of the receiving box, and a new fuse is installed inside the fuse mounting seat, so that the device can quickly replace the fuse without opening the sealed box. Avoid manual operation and improve safety.
Description
technical field [0001] The invention relates to the technical field of fuse replacement, in particular to an automatic replacement device for sealed fuses of distribution boxes. Background technique [0002] A fuse is an electrical appliance that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made by using this principle. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment. As short circuit and overcurrent protectors, fuses are one of the most commonly used protection devices. [0003] When the existing sealed fuse is damaged, it needs to be replaced manually. Often, the fault needs to be checked manually before it can be deter...
