Abstract
The utility model discloses a locating pin of a disconnector which comprises a pin head segment, a screw thread segment and a pin tail segment, wherein the diameter of the pin head segment is 12mm and is less than the large diameter of screw thread of the screw thread segment; the length of the pin head segment is 15mm; the pin tail segment is in the shape of a hexagonal nut; and the pin tail segment is provided with through holes along the direction which is perpendicular to the axes of the locating pin. The locating pin avoids the condition that a power supply line is stopped to be overhauled as the locating pin of the disconnector is stuck and is hardly withdrawn, thereby being applicable to high voltage disconnectors such as 110kV, and the like.
Description
Technical field
The utility model relates to power equipment part field, especially relates to a kind of isolating switch alignment pin.
Background technology
The isolating switch alignment pin is mainly used in the separating brake of isolating switch actuating handle, the situation that puts in place of closing a floodgate, but extremely causes the maintenance of stopping transport because of operating handle locking alignment pin bite rust sometimes.Its reason is, polluting very serious area, though isolating switch manual operation handle locking has certain Sealing Device, but growth along with the time, the hardening gradually of lubricant on the operating handle, minimizing, locking appearance bite phenomenon gradually, above-mentioned reason belongs to external environmental factor; In addition, in the present alignment pin manufacture process, at spring the back is installed and adopts welding manner, cause a hidden trouble for the alignment pin corrosion.And at present pin and bushing pipe gap are too small, and anvil cinder or pin corrosion all may cause the pin corrosion and be difficult to extract after the spring corrosion.
The utility model content
In view of this, the purpose of this utility model is to overcome the defective of prior art, and a kind of isolating switch alignment pin is provided, and avoids being difficult to extract because of alignment pin is stuck causing the stop transport situation of maintenance of supply line.
For achieving the above object, the utility model by the following technical solutions:
Isolating switch alignment pin of the present utility model comprises stem knob section, thread segment, pin rear; Stem knob section diameter is 12mm, and less than the thread segment Major Diam, the length of stem knob section is 15mm; The pin rear is the hexagonal (hexagon)nut shape, and along the direction vertical with this alignment pin axis through hole is set at the pin rear.
Further, Major Diam is 18mm, and thread segment length is 30mm.
Further, whole alignment pin adopts stainless steel.
The beneficial effects of the utility model are:
Because locating pin structure is reasonable in design, adopt the segmentation form, stem knob section diameter and length and bushing pipe fit clearance are suitable, and thread segment cooperates with nut and is used for the location, and the pin rear adopts the hexagonal (hexagon)nut shape and through hole is set to be convenient to screw.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification and the accompanying drawing.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in drawings, the isolating switch alignment pin of present embodiment comprises stem knob section 1, thread segment 2, pin rear 3; The diameter of stem knob section 1 is 12mm, and less than the thread segment Major Diam, the length of stem knob section 1 is 15mm; Pin rear 3 is the hexagonal (hexagon)nut shape, and along the direction vertical with this alignment pin axis through hole 5 is set on pin rear 3, the axis of through hole 5 and the axes intersect of alignment pin.Major Diam is 18mm, and the length of thread segment 2 is 30mm.Whole alignment pin adopts stainless steel.During enforcement alignment pin cap 4 can be set at the end of pin rear 3, with convenient manually rotation drawing.The isolating switch alignment pin of present embodiment has following advantage:
1, adopt stainless steel material to be difficult for getting rusty;
2, can satisfy breaking-closing operating handle positioning action;
3, can satisfy the five-defence block requirement;
4, be convenient to safeguard replacing;
5, successful reduction the stoppage in transit maintenance number of times that extremely causes because of operating handle locking alignment pin bite rust of 110KV isolating switch.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
