An electronic low-voltage fuse box using a nylon slider

Abstract

The invention discloses an electronic type low-voltage fuse box adopting a nylon sliding block, and belongs to the field of emergency protection devices. The electronic type low-voltage fuse box adopting the nylon sliding block comprises a breaker switch body arranged in a box body, and the breaker switch body is slidably arranged on a slide rail in the box body. The electronic type low-voltage fuse box adopting the nylon sliding block is characterized in that the sliding block is arranged at the lower end of a breaker switch, and the breaker switch body is slidably borne on the slide rail in the box body through the sliding block; the two ends of the sliding block are of semicircular structures, and form a complete circular sliding block with a middle horizontal part; the horizontal part of the sliding block comprises an upper cross beam and a lower cross beam, and at least one longitudinal reinforcing rib is arranged between the upper cross beam and the lower cross beam. The mode of combining hard contact and soft contact is adopted in the electronic type low-voltage fuse box adopting the nylon sliding block, the nylon sliding block and the slide rail are in surface contact type matching, the various defects of the original sliding type mode of point contact can be avoided, the characteristics of nylon materials are utilized, and the aims of reducing the workload of maintaining outdoor line equipment and guaranteeing the long-time stable operation of on-site equipment are achieved. The electronic type low-voltage fuse box adopting the nylon sliding block can be widely applied to the field of designing and manufacturing low-voltage power distribution equipment.

Description

technical field [0001] The invention belongs to the field of emergency protection circuit devices, in particular to an emergency protection circuit device used in low-voltage power supply and distribution systems. Background technique [0002] With the development of the economy and the improvement of people's living standards, the electricity consumption in cities has increased significantly. At present, there are more and more outdoor pole-mounted transformer installations in the urban 10kV distribution network, and the consumption of matching transformer fuse boxes is also increasing year by year. Increase. [0003] The low-voltage distribution transformer fuse box is one of the important equipment in the outdoor pole transformer device of the low-voltage power distribution network. It is installed between the low-voltage end of the transformer and the low-voltage power grid. Operate its "open" and "close" to realize the input and cut-off operation of the low-voltage pow...

AI Technical Summary

Problems solved by technology

[0011] Since the existing slideways and slide rods are all metal components, the two are in a "hard-hard contact" mode. First, additional lubricants are required for lubrication, and regular cleaning and wiping and replacement of lubricants are required, which increases the Line inspection and maintenance workload; second, the friction between the slideway and the slide bar is serious. When used, because it is a "point contact" structure mode, the friction force is relatively large, and its service life is low, which is not conducive to the maintenance of on-site equipment. Safe and stable operation for a long time
