A drop-out fuse replacement device

Abstract

The invention discloses a drop fuse replacement apparatus. The drop fuse replacement apparatus comprises a top plate, wherein a pair of linkage mechanisms are symmetrically connected to the front and back sides of the left end part of the top plate through a rotary shaft; each linkage mechanism comprises a rotary rod, a connecting plate, a hanging ring and a telescopic insertion rod; the connecting plate is provided with the hanging ring connected with a hook; each connecting plate is connected with a drop fuse; a fixed pulley and an insertion rod are arranged on the right side of the rotary shaft in sequence; the hook and the hanging ring connected with one connecting plate through the hook are arranged at one end of a cable rope penetrating through the fixed pulley; the other end of the cable rope is connected with a side wall of a winding column; a limiting insertion hole for the winding column to be inserted is formed in the insertion rod; a plurality of insertion holes are formed in the outer side wall of the rotary shaft of the fixed pulley; the telescopic insertion rod is arranged on the connecting plate; and a plug capable of being inserted and fixed in the insertion hole is arranged at the top of the telescopic insertion rod. According to the apparatus, a mounting angle of the drop fuse can be adjusted and the drop fuse can be firmly fixed and mounted; and a standby apparatus is provided, so that after a used device is damaged, the replacement and installation can be conveniently carried out and the repair efficiency can be improved.

Description

Technical field [0001] The invention relates to a drop-out fuse installation and replacement auxiliary equipment, in particular to a drop-out fuse installed between the drop-out fuse and a cross arm, which can adjust the installation angle of a fixed drop-out fuse according to actual application requirements, and has a spare device. Drop-out fuse replacement device that is convenient for maintenance and replacement. Background technique [0002] Drop-out fuse is the most commonly used short-circuit protection switch for 10kV distribution line branch lines and distribution transformers. It has the characteristics of economy, easy operation, and strong adaptability to outdoor environments. It is widely used in 10kV distribution lines and power distribution. The primary side of the transformer is used for protection and equipment switching and switching operations. The drop-out fuse is installed on the 10kV distribution line branch line, which can reduce the scope of power outage, ...

AI Technical Summary

Problems solved by technology

At present, dropout fuses have different models and manufacturers, the voltage level is not high, the installation process is uneven, and the installation angle is not reasonable. In addition, the operating environment of the installation site is also different, so it is directly installed on the cross arm. , will cause the drop-out fuse to fail to effectively drop after the fuse is blown to cut off the fault, resulting in the expansion of the scope of the accident and causing huge losses. Therefore, it is necessary to develop an auxiliary installation device to ensure a firm and reliable fixation of the drop-out fuse While installed on the cross arm, the installation angle can be flexibly adjusted according to the actual needs of the operation site to ensure the normal operation of the dropout fuse

At the same time, when the drop-out fuse is damaged and needs to be replaced, the maintenance personnel need to carry a new fuse, take off the damaged fuse, readjust the installation angle of the fuse to be replaced, install the fuse, and the operation is troublesome, and Limited by the materials at hand of maintenance personnel, an auxiliary installation device with its own spare equipment and simplified steps to adjust the installation angle is needed, which facilitates the replacement and installation of drop-out fuses, simplifies workers' work, and improves maintenance efficiency
