Abstract
The invention discloses a novel auxiliary switch-off spring structure, which comprises a connecting rod, a guide sleeve, a lower support plate, an upper support plate, a spring, a crank arm and a support rod. The structure drives the connecting rod to upwards and downwards move through the crank arm so as to carry out compression deformation on the spring, the distance between the upper support plate and the lower support plate is reduced through screw nuts for regulating the pre-compression of the spring, the connecting rod is guided to smoothly slide during the switch-off operation through the guide sleeve, and the compression deformation capability of the spring is realized through regulating the adjustable screw nuts arranged on the connecting rod. The novel auxiliary switch-off spring structure has the characteristics that the structure is simple, the size is small, the use is flexible, the regulation is convenient, and the like.
Description
Technical field
The present invention relates to the auxiliary tripping spring structure in a kind of high voltage switchgear.
Background technology
For primary cut-out, opening velocity is the important indicator that circuit breaker has connecting-disconnecting function, generally need change opening velocity by rigidity or the precommpression of adjusting tripping spring stroke or spring, but influence closing speed simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of auxiliary tripping spring structure that had not only improved opening velocity but also do not changed closing speed, for achieving the above object, the technical solution used in the present invention is:
This structure comprises connecting rod, fairlead, bottom plate, mounting plate, spring, connecting lever and four support bars, the upper end of each support bar is vertically passed the diverse location at mounting plate edge respectively, and nut and mounting plate by correspondence are fixed, the lower end of each support bar is vertically passed the diverse location at bottom plate edge respectively simultaneously, and nut and bottom plate by correspondence are fixed, and the center position of mounting plate and bottom plate has circular hole
And circular hole
, the top of fairlead is fixed with the disk of horizontal positioned, and the mid portion of disk is positioned at fairlead and the marginal portion leans out fairlead, and the center position of disk has circular hole
, circular hole
, circular hole
And circular hole
Central point overlapping in vertical direction, circular hole
The aperture equal circular hole
The aperture and less than the internal diameter of fairlead, circular hole
The aperture be slightly larger than the external diameter of fairlead, spring is located between bottom plate and the mounting plate, the upper end of spring is fixed on the bottom surface of mounting plate, fixedly connected with the upper end of fairlead in the lower end of spring, the lower ends downward of fairlead is passed circular hole
, spring and fairlead are enclosed within respectively on the connecting rod, and the upper end and the connecting lever of connecting rod are hinged, and the lower ends downward of connecting rod is passed circular hole successively
, circular hole
And circular hole
, the lower thread of connecting rod is connected with adjustable nut, and adjustable nut is positioned at fairlead and below disk, and the external diameter of adjustable nut is slightly less than the internal diameter of fairlead and greater than circular hole
The aperture, when connecting rod is positioned at minimum point, lean out the end face of the marginal portion roof pressure bottom plate of fairlead in the disk, when connecting rod is positioned at peak, be positioned at the bottom surface of fairlead part in the adjustable nut roof pressure disk.
This structure moves up and down by the connecting lever drivening rod spring is carried out compression, regulate the distance of supporting plate up and down by nut, come the precommpression of spring is adjusted, be used for guide link by fairlead and slide smoothly when the separating brake, realize the compression power of spring by regulating adjustable nut on the connecting rod.This structure has realized comprehensive adjusting opening characteristic, provides a bigger strength at the separating brake initial stage, and separating brake later stage strength reduces, and helps the initial stage speed of closing a floodgate simultaneously, has reduced the operating work requirement of spring operating mechanism.Characteristics such as this structure has simple in structure, and volume is little, uses flexibly, and is easy to adjust.
