Description
Technical field
Become distribution technique field the invention belongs to electric power, be related to a kind of work for powered installation and removal high-tension fuse
Tool.
Background technology
Voltage transformer and house transformer in power station or switch cubicle generally use high-tension fuse as protection equipment,
In operation because a variety of causes causes to need to disassemble the fusion tube of damage from fuse base after fuse blows, so
Intact fusion tube is arranged on fuse base afterwards.Because fuse and neighbouring electrical equipment and bus are with height
Pressure, changing fuse needs that first fuse and relevant device have a power failure and can carry out after reliable ground, attached for fuse
Nearly live part is complicated or switch cubicle in narrow space situation, generally require to expand the even full ability that has a power failure of power failure range
It can guarantee that the safety for changing fuse operation.Equipment required for changing fuse has a power failure and can bring huge economic loss, certain
Complete have a power failure is nearly impossible in a little important power stations, if can not change fuse in time will influence the normal fortune of equipment
OK.
Two kinds of action bars clamped-in style and screw rod clamped-in style are broadly divided into currently used for the instrument of powered handling fuse.It is public
Number Chinese invention patent for being CN103996982A is accused, " a kind of high-tension fuse takes holding tool " is disclosed, it is by operating thick stick
Bar pressure handle drives the pull bar in hollow insulating bar to drive arc clip to clamp fusion tube.It is such a action bars clamp fusion tube by way of
Defect be there is, it is necessary to which one hand-held insulating bar of operating personnel is close to fusion tube, another hand is clamped operation, in operating process
The power that the clamping force of fusion tube is applied by hand on action bars is maintained, and is difficult holding instrument stable and fusion tube clamping force constant.
In addition, the pull bar inside hollow insulating bar is not easy to measure state of insulation, it is difficult to ensure live-working safety.
Notification number is CN103137393A Chinese invention patent, discloses " a kind of taking tool for high-voltage fuse ", its
Fusion tube is clamped by screw rod.Although such a support by way of screw rod clamps fusion tube and clamping fusion tube use same exhausted
Edge bar, but need multi-turn rotation insulating bar to clamp fusion tube in operation, the operating time is longer, and single section folder fusion tube is difficult
To ensure that fusion tube is stable.
The content of the invention
Can be in the case where fuse have a power failure ground connection easily and quickly by fusion tube it is an object of the invention to provide one kind
What is disassembled on fuse base or from base is easy to operate, keeps instrument stable constant with fusion tube clamping force
The powered handling instrument of high-tension fuse.
The present invention solves the scheme that is used of its technical problem：
The powered handling instrument of high-tension fuse, is made up of insulating bar 1 and termination, and termination is by the relative both sides of bottom plate 2 and shape phase
Connected and composed with, arc-shaped slot 4 in opposite direction, two arc-shaped slots 4 axial plane in termination is projected as a complete circle, circle
Diameter is equal to or more than fusion tube diameter, and the upper and lower inwall tangent with circle of each neck 4 respectively has an elastic clamp device 5 with melting
Guan Yuanbi is dynamic to be coordinated.
The elastic clamp device 5 includes spring 6 and roller 7, and there are hole and the dynamic cooperation of spring shaft in the axle bed two ends of roller 7,
Spring shaft is fixed on the upper and lower inwall of neck 4, and spring 6 is enclosed on the axle bed that roller 7 is pushed down on spring shaft, and spring 6 is compressed by roller 7
Afterwards, the upper and lower inwall of neck 4 can be by fusion tube diameter, after spring 6 discharges, with respect to the week of two rollers 7 with respect between two rollers 7
Face and the arcwall face of neck 4 are matched for clamping tightly fusion tube.
The elastic clamp device 5 is the arc-shaped spring piece that one end is connected with neck 4.
Roller 7 is made of elastomeric material.
Operating personnel's hand-held insulating bar afterbody when dismantling fuse, makes fusion tube enter termination openings, rotationally clockwise
90 ° of insulating bar, fusion tube by roller compression spring and enters 2 necks, each card under leverage with roller rolling friction
Fusion tube is fixed on neck bottom by groove in the presence of 2 groups of elastic clamp devices, and 2 necks fix 2 sections of fusion tube, to
Insulating bar is pulled to disassemble fusion tube from fuse base afterwards.Operation order and the disassembling section for installing fuse are suitable
Sequence is opposite.
That invents has the beneficial effect that：
The present invention can be used safely and fast to mount and dismount under conditions of fuse and associated high voltage equipment do not have a power failure high
Press fuse, it is only necessary to insulating bar is rotated 90 ° locking and unblock of the termination to fusion tube can be achieved, it is simple to operate, it is easy to use,
Small is required to operating space, with higher operating efficiency.Termination fixes 2 sections of fusion tube by 2 necks, it is to avoid fusing
Rocking after device is fixed in instrument.The present invention is by neck and spring and rubber roll with adjustable pressure are reliably solid
Determine fusion tube, roller is contacted with fusion tube surface scrolls, it is light and handy flexible to lock and unlock fusion tube action, will not damage porcelain fusion tube.Fusing
The installation and removal work of device does not influence the normal operation of other electrical equipments, ensures the safety of operating personnel.

Embodiment
The powered handling instrument of high-tension fuse, as shown in figure 1, including insulating bar 1 and termination, afterbody insulating bar 1 is used for branch
Hold termination and keep the safe distance between operating personnel and fuse and other live parts, opening 3 is set in the middle part of termination, be open
3 both sides set 2 necks 4 in opposite direction, and each neck sets the relative clamping device being made up of spring 6 and roller 7 in 2 groups of positions
5。
In fig. 2, the width of opening 3 at the middle part of termination bottom plate 2 is more than fusion tube diameter, in order to which fusion tube enters opening 3.
In figure 3, the width of neck 4 coordinates with fusion tube diametric clearance, rounding at the opening of neck 4, in order to which fusion tube can be suitable
Profit enters neck 4.2 necks 4 are parallel to each other and opening direction is on the contrary, the face that the opening center of neck 4 is constituted is hung down with insulating bar 1
Directly.In Fig. 4, the position of 2 stack clamping device 5 of each neck 4 is relative, and fusion tube passes through the compression spring 6 of roller 7 when entering neck 4
Into the bottom of neck 4, fusion tube is clamped under the effect of spring 6 by 2 rollers 7 and the bottom of neck 4, and 2 necks 4 fix fusion tube respectively
2 sections.Roller 7 uses elastomeric material, and the pressure of spring 6 can be adjusted.
