Description
Technical field
The utility model relates to a kind of isolating switch of transformer station, particularly a kind of isolating switch fingertip erecting tools.
Background technology
Existing isolating switch is the common device of transformer station, and in transformer station, ubiquity and quantity are very large.The heating of isolating switch fingertip is most common failure in substation equipment maintenance and repair, is mainly that the aging fingertip that makes of 110kV-220kVGW4 type disconnecting link Extension Spring-type disconnector contact-finger spring is loosening, need to change fingertip spring.After replacing, need re-start installation to fingertip.Because fingertip number springs is many, pulling force is huge, relies on manpower limit to press pressing spring limit in the past the not only operating difficulties of method of fingertip is installed, and have very large danger.
Summary of the invention
Based on this, the utility model is to overcome the defect of prior art, and a kind of isolating switch fingertip erecting tools is provided, more convenient simple and easy can make switch touching refer to install time, also safer.
Its technical scheme is as follows: a kind of isolating switch fingertip erecting tools, comprise polylith fixed head, branched screw rod and multiple nut, screw rod is provided with positioning area, the first threaded area and the second threaded area, positioning area is between the first threaded area and the second threaded area, positioning area is provided with protuberance at both sides end, fixed head is provided with multiple holes, hole bore is greater than the bore of the first threaded area, the second threaded area but is less than the bore of protuberance, and the bore of the bore of nut and the first threaded area, the second threaded area is suitable.
Below further technical scheme is described:
Described fixed head is rectangle.
Described screw rod is provided with handle portion in centre.
The cross section of described protuberance is circle or polygon.
On the center line that is centered close to fixed head of described hole.
Below principle, the effect etc. of aforementioned techniques scheme are described:
1, described isolating switch fingertip erecting tools is simple in structure, easily device, easy to operate.
2, locate disconnector contact-finger by fixed head, then by turning nut, fixed head is drawn in, thereby disconnector contact-finger is drawn in and fix, so just make installation, replacing, all more convenient easy row of maintenance of disconnector contact-finger, also improved fail safe.

Embodiment
Below embodiment of the present utility model is elaborated:
As shown in Figures 1 to 5, a kind of isolating switch fingertip erecting tools, comprise polylith fixed head 10, branched screw rod 20 and multiple nut 30, screw rod 20 is provided with the first threaded area 21, the second threaded area 22 and positioning area 23, positioning area 23 is between the first threaded area 21 and the second threaded area 22, positioning area 23 is provided with protuberance 24 and handle portion 25, the cross section of protuberance 24 is circle or polygon, fixed head 10 is rectangle, which is provided with hole 15, the bore of hole 15 is greater than the first threaded area 21, the bore of the second threaded area 22 but be less than the bore of protuberance 24, on the center line that is centered close to fixed head 10 of hole 15, the bore of nut and the first threaded area 21, the bore of the second threaded area 22 is suitable.
While installing and using, as shown in Figure 1, the first fixed head 11 and the second fixed head 12 on the first threaded area 21, the 3rd fixed head 13 and the 4th fixed head 14 can move up and down on the second threaded area 22, in the time of operation, the one end of inserting disconnector contact-finger between the first fixed head 11 and the second fixed head 12, between the 3rd fixed head 13 and the 4th fixed head 14, insert the other end of disconnector contact-finger, then by turning nut 30, the first fixed head 11 and the second fixed head 12, the 3rd fixed head 13 and the 4th fixed head 14 are drawn in, thereby disconnector contact-finger is drawn in and fix.
The present embodiment tool has the following advantages:
1, described isolating switch fingertip erecting tools is simple in structure, easily device, easy to operate.
2, locate disconnector contact-finger by fixed head 10, then by turning nut 30, fixed head 10 is drawn in, thereby disconnector contact-finger is drawn in and fix, so just make installation, replacing, all more convenient easy row of maintenance of disconnector contact-finger, also improved fail safe.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
