Abstract
The utility model belongs to a 35kV bus potential transformer high-voltage fuse replacing booster used in 110kV and 35kV transformer stations. Force is acted on pull bars of right-handed screw rods and pull bars of left-handed screw rods from two sides by the rotation of central frapping screw nuts. Force with direction to the center fraps a cover cap of a fuse ceramic sleeve. The booster is an assistant tool which reduces dangerousness of operation of workers and which quickens replacing time. The tool comprises right-handed screw rods, left-handed screw rods, frapping bolts, and baffle pates. By the rotation of the frapping bolts, the tool sustains force from two sides. The frapping force with direction to the center fraps the cover cap of the fuse ceramic sleeve, thereby facilitating the replacement of a high-voltage fuse. The fixing screw rods can be guaranteed not to suffer from slipping in order to prevent the screw rods from dropping. Working task of replacing the fuse is relieved and simplified for workers. The number of workers is decreased by one so that a manner that one worker operates while one worker monitors is guaranteed. Therefore, the workload of the workers is reduced and safety factor is increased. In addition, replacing time is shortened so that an adverse factor of a long-time unsafe operation of a voltage parallel device is prevented.
Description
Technical field
The utility model instrument belongs to the Work tool technical field, relates in particular to 110kV and the 35kV 35kV of transformer station bus-bar potential transformer high-voltage insurance replacing booster.
Background technology
According to the relevant requirements of " 18 great anti-accident measures of electrical network of State Grid Corporation of China ", due to high-voltage insurance fusing, essential application at once has a power failure and changes insurance, need to climb up framework, belongs to work high above the ground.During replacing, base oneself upon shakiness, be unfavorable for exerting oneself, and need 2 people's ascend operations, the transformer station of existing O﹠M station administration is more, and personnel's task is busier, so when changing insurance, occur without working under the monitoring state unavoidably, has increased unsafe factor.
Summary of the invention
The purpose of this utility model is in order to overcome defects, designed a kind of simple structure, safe and reliable, light and flexible, satisfy the work on the spot requirement, can conveniently pass in and out the 35kV high-voltage insurance replacing, satisfy the work on the spot requirement, replacing tool for helping easy to use, with low cost-35kV bus-bar potential transformer high-voltage insurance replacing booster.
A kind of 35kV bus-bar potential transformer of the utility model high-voltage insurance replacing booster comprises positive silk bolt, anti-silk bolt, tightens up nut, left side baffle plate, right side baffle plate, described positive silk bolt arranges 2, positive silk bolt form T-shaped bar without silk end vertical welding one cross bar, T-shaped bar two ends are fixed on left side baffle plate upper and lower end parts; Described anti-silk bolt arranges 2, anti-silk bolt form T-shaped bar without silk end welding one cross bar, T-shaped bar two ends are fixed on both sides, baffle plate up and down, right side; Described positive silk bolt and anti-a bolt medial extremity with tighten up nut thread and be connected.
A kind of 35kV bus-bar potential transformer of the utility model high-voltage insurance replacing booster has following beneficial effect compared with prior art: the utility model booster has adopted the pull bar of positive and negative silk, rotate by centre bolt, both sides are simultaneously stressed, direction is to the power at center, the block of insurance insulator is tightened up, alleviate the danger that personnel exert oneself.
The utility model not only alleviates and succinct personnel change the task of insurance, has reduced simultaneously by people's work, and has guaranteed the people people's monitoring of working, and has lowered personnel's workload, has improved coefficient of safety.Shorten the replacing time, avoid the uneasy congruent unfavorable factor of voltage parallel device long-time running.

Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of 35kV bus-bar potential transformer of the utility model high-voltage insurance replacing booster technical scheme is described in further detail.
As shown in Fig. 1-4, a kind of 35kV bus-bar potential transformer high-voltage insurance replacing booster comprises positive silk bolt 1, anti-silk bolt 2, tightens up nut 3, left side baffle plate 4, right side baffle plate 5, described positive silk bolt 1 arranges 2, positive silk bolt 1 form T-shaped bars without silk end vertical welding one cross bar 6, T-shaped bar two ends are fixed on left side baffle plate 4 upper and lower end parts; Described anti-silk bolt 2 arranges 2, anti-silk bolt 2 form T-shaped bars without silk end welding one cross bar 6, T-shaped bar two ends are fixed on the right side baffle plate, and Shang Xia 5 both sides; Described positive silk bolt 1 and anti-silk bolt 2 medial extremitys with tighten up nut 3 and be threaded.
Embodiment 1.
Novel 35kV high-voltage insurance replacing tool of the present utility model, this instrument is comprised of forward lead screw, tightening bolt, baffle plate, and this instrument of this instrument rotates by tightening bolt, both sides are simultaneously stressed, direction is tightened up to the receipts power at center the block that insures insulator, is convenient to change high-voltage insurance.
Positive silk bolt 1 is the structure of a T-shape, it is cross bar 6 that bolt does not have iron of a threaded end vertical welding, cross bar 6 two ends are horizontally through left side baffle plate 4 top circular holes, can 360 ° of rotations, after cross bar 6 passes left side baffle plate 4, an aperture is beaten on both sides on cross bar 6 two ends, fix with split pin, guarantees can not drop.The structure installation method of anti-silk bolt 2 and right side baffle plate 5 is identical with left side baffle plate 4 with positive silk bolt 1.Positive and negative bolt and the middle nut 3 that tightens up are one, and the bottom hole of baffle plate 4 and baffle plate 5 is openings, and the cross bar of positive and negative bolt will snap into open pore.Rotate simultaneously the nut that tightens up of up and down, the bolt of positive and negative silk screws simultaneously, and reaching left side baffle plate 4 and right side baffle plate 5 is all inside strength, and both sides are simultaneously stressed, and direction is tightened up to the receipts power at center the block that insures insulator, is convenient to change high-voltage insurance.
The 35kV high-voltage insurance replacing tool can guarantee that fixed screw can filigree, and screw should not be dropped.
Operation principle and using method: after fuse replacement is good, the first half of booster is stuck on the insurance insulator, then the latter half is placed in below the insurance insulator, the survivor of a murder attempt place that both sides are stuck in left baffle rotates tightening bolt, tightens up the block of insurance insulator by rotation, and it is stressed even to block a shot, fixed screw that can rapid first-class block reduces workload, has accelerated the replacing time.
