Intelligent short-circuit protection device for electrical distribution box and use method of intelligent short-circuit protection device

Abstract

The invention relates to the technical field of electrical equipment, and discloses an electrical distribution box intelligent short circuit protection device, which comprises an inner rotating block and fuse wires, the outer part of the inner rotating block is fixedly connected with an adjusting gear ring, and the inner part of the inner rotating block is provided with six groups of inner channels for installing the fuse wires. The exterior of one end of the inner rotating block is fixedly connected with six groups of joint seats, and the interiors of the six groups of joint seats are movably connected with movable electrode bars; an adjusting motor is controlled to start through a microcontroller, the adjusting motor drives an inner rotating block to rotate by one sixth circle through an adjusting worm and an adjusting gear, different groups of movable electrode bars and positioning electrode bars can be conveniently switched to be connected into a circuit, the replacement frequency of a fusing protection part can be reduced, the frequency of circuit contact can be reduced, and the safety of the fuse protection part is improved. And when the whole fuse needs to be replaced and fused, the fuse wire is replaced outside by disassembling the inner rotating block, so that the fuse wire is prevented from being directly replaced in a circuit, and the use safety of the device is further ensured.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an intelligent short-circuit protection device for an electrical distribution box and a method for using the same. Background technique [0002] The electrical distribution box is used to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on the screen, reasonably distribute electric energy, and open and close the circuit. It has a high level of safety protection and can intuitively display the conduction state of the circuit. It is the control center that instructs various components in the power supply line to reasonably distribute electrical energy. In order to ensure the safety of electrical components inside the distribution box, a circuit is usually installed. Short circuit protection device, in order to ensure the corresponding response speed of short circuit and improve the p...

Problems solved by technology

Although it is convenient to replace, it still needs to be replaced once a fault occurs, which still leads to complicated operation and increases the difficulty of operation. At the same time, the replacement of the fuse requires the replacement of the whole fuse, which cannot be replaced only for the fuse, resulting in a large number of fuses. Material waste increases replacement costs, and when replacing or installing in this patent, it is carried out directly in the circuit, which increases the operating risk of the operator and easily leads to the risk of electric shock for the operator. The fuse in this patent is directly exposed to the outside, resulting in its It is easily affected by the dust entering the interior of the electrical equipment, resulting in misjudgment of the short circuit of the circuit, and the fuse is blown under the influence of dust, reducing the use effect of the device

At the same time, when the fuse is blown, the fusing effect cannot be guaranteed, and it is easy to cause broken wire contact, resulting in secondary connection of the circuit, which not only affects the protection effect, but also greatly increases the operating risk of maintenance personnel.
