Description
Technical field
The present invention relates to electric equipment maintenance, and in particular to electric equipment maintenance instrument is a kind of for changing fuse
Clamper.
Background technology
In transformer station, because many reasons such as harmonic wave or operation cause voltage ripple of power network scope larger, fuse two
Rubber cushion aging, poorly sealed rainwater intrusion etc. are held, causes PT fuse blows numbers more, it is necessary to quick-replaceable fusing in time
Device, ensure that PT functions recover normal operation within the most short time.In order that outdoor 35kV PT fuses both ends conductive part taps
Touch well, the pressure texture that the internal structure design of fuse sleeve pipe is that both ends are spring is caused fuse by producer
Sleeve pipe elastic force is big, at least needs during replacing two people high-altitudes cooperations to complete, work high above the ground narrow space, larger safety be present
Hidden danger, in fixed roof, the elastic force of two springs in both ends is offset with manpower, staff is firmly difficult to uniformly, if firmly
Degree is inadequate, will result in the loose contact of fuse both ends, and fuse is then easier to fuse, and also occurs screw hole dislocation often,
Top cover is difficult to fix.
The Chinese patent of Application No. 200910064783.9 and 200920090015.6 discloses a kind of outdoor 35KVPT
Fuse special replacement tool, the instrument includes the insulator chuck be arrangeding in parallel and porcelain bushing shell is taken over a business, insulator chuck and porcelain
Sleeve pipe takes over a business correspondence position and is provided with bayonet socket, and insulator chuck and porcelain bushing shell are provided with spacing adjusting device between taking over a business, the spacing is adjusted
The screw rod and nut that regulating device is taken over a business by two perpendicular to insulator chuck and porcelain bushing shell form, in use, knob nut is in spiral shell
Position on bar come realize insulator chuck and porcelain bushing shell take over a business between spacing regulation, and then fuse contained spring is carried out
Extruding so that fuse side covers to be reduced by spring force, (one), existing so as to be the problem of carrying out the replacing of fuse, exist
Spacing adjusting device disclosed in technology is screw rod and nut, when in use, is only capable of being adjusted in side, because torque is larger and
The reason for fuse contained spring elastic force is larger, in regulation, operating personnel need to use larger strength and can be just adjusted；
(2), spacing adjusting device disclosed in prior art is by two screw rods and nut taken over a business perpendicular to insulator chuck and porcelain bushing shell
Composition, in regulation, it is necessary to rotate two nuts simultaneously to keep the balanced, symmetrical that insulator chuck and porcelain bushing shell are taken over a business, so
Either just need operating personnel's both hands to be operated, or it is alternately rotated two nuts；And 35Kv high-voltage and current-limitation fuses are general
It is aerial to be arranged on height, if operating personnel's both hands are all used to operate adjusting means, there may be the danger dropped or slid, together
When, even if operating personnel are alternately rotated two nuts, first, can not ensure insulator chuck and porcelain bushing shell takes over a business certain balance, two
It is to need the long period to complete, accordingly, there exist the problem of one-handed performance inconvenience and low operating efficiency.
The content of the invention
The technical problems to be solved by the invention are：A kind of the shortcomings that overcoming prior art, there is provided simple in construction, user
