Summary of the invention
The problem to be solved in the present invention is to provide a kind of solid loop-net cabinet of on-load switch linkage mechanism, and tripping operation not easily appears in this solid loop-net cabinet, and its on-load switch link gear structure is simple, manufacture and maintenance cost lower.
For solving the problem, take following technical scheme:
The solid loop-net cabinet of on-load switch linkage mechanism of the present invention comprises cabinet, has insulating cylinder body, have on-load switch in insulating cylinder body in cabinet.Described on-load switch comprises restrictor bar, and one end of restrictor bar is hinged on the outlet rod of insulating cylinder body.There is casing above described insulating cylinder body, a sidewall of casing has through hole, has drive rod in through hole, be rotating between drive rod and through hole.Gangbar is had in described casing, the two ends of gangbar are rotating respectively with between the corresponding sidewall of casing, gangbar and drive rod perpendicular, and between drive rod one end in gangbar and casing by bevel gear in being linked, the drive rod one end be positioned at outside casing is stretched out outside described cabinet.Described gangbar has quarter butt, and one end of quarter butt is with gangbar in being fixedly connected with, and the axis perpendicular of the longitudinal centre line of quarter butt and gangbar, the other end of quarter butt is hinged with connecting rod, and the other end of connecting rod is hinged on the middle part of described restrictor bar through bottom half.Compression spring mechanism is connected with between the middle part being characterized in the wall box that quarter butt one end that described connecting rod is corresponding is relative with described through hole.
Wherein, described compression spring mechanism comprises urceolus and inner core, and the internal diameter of urceolus is greater than the external diameter of inner core, and the openend of inner core stretches in urceolus, and has Compress Spring between the intracavity bottom of the intracavity bottom of urceolus and inner core; In hinged cooperation between the middle part of the wall box that the blind end of described urceolus is relative with through hole, the blind end of inner core and one end of quarter butt are hinged cooperation.
Further improvement of the present invention scheme is that described insulating cylinder body comprises body, and body has inner chamber, and it is made up of insulating material.The upper end of described body is opening-like, has vertical through holes bottom it, the intracavity inter-connection of this vertical through holes and body.A sidewall of described body has wire outlet seat, and wire outlet seat has cross through hole, the intracavity inter-connection of this cross through hole and body, and described outlet rod is positioned at this cross through hole.Have baffle plate between the sidewall at described vertical through holes and cross through hole place, baffle plate is connected in one with body.The baffle plate one side equal undulate from top to bottom that the inner body wall that described cross through hole is relative, cross through hole are relative, makes the equal indention of cross section in this body sidewall, this face of baffle plate.Body sidewall above described wire outlet seat there is observation panel.This insulating cylinder body utilizes corrugated curved surface on inner body wall, baffle plate to replace plane of the prior art, when creepage distance requires identical, its whole height is lower, small volume, is conducive to transport and installs, also can reduce height and the volume of solid loop-net cabinet simultaneously.
Take such scheme, have the following advantages:
Have insulating cylinder body in cabinet due to the solid loop-net cabinet of on-load switch linkage mechanism of the present invention, have on-load switch in insulating cylinder body, on-load switch comprises restrictor bar; Have casing above insulating cylinder, in casing, have drive rod and gangbar, gangbar and drive rod perpendicular, and between drive rod one end in gangbar and casing by bevel gear in being linked; Gangbar there is quarter butt, one end of quarter butt with gangbar in being fixedly connected with, and the axis perpendicular of the longitudinal centre line of quarter butt and gangbar, the other end of quarter butt is hinged with connecting rod, the other end of connecting rod is hinged on the middle part of described restrictor bar through bottom half, and is connected with compression spring mechanism between the middle part of quarter butt one end corresponding to connecting rod wall box relative with described through hole.When described quarter butt turns to peak or minimum point, the Compress Spring decrement in compression spring mechanism is less or do not have; When quarter butt is moved to middle part by height point or moved to middle part by low spot, the decrement of Compress Spring increases gradually, and the resistance that drive rod rotates is larger; When quarter butt is moved to height point or low spot by middle part, the decrement of Compress Spring reduces gradually, and drive rod rotates non-resistance.Therefore, the on-load switch link gear in this solid loop-net cabinet carry out divide-shut brake control time, when lock is in separating brake or "on" position, be compressed the effect of spring thrust, quarter butt position can not be moved, and namely the restrictor bar position of on-load switch remains unchanged, and can guarantee the phenomenon not occurring tripping.Meanwhile, the structure of compression spring mechanism is comparatively simple, manufacture and maintenance cost also relatively low.
