Abstract
The utility model discloses a distribution transformer tapping switch fastening tool, including the sleeve and fixed of suit on the tapping switch nut set up the sleeve top and with the spliced pole of sleeve coaxial line, be provided with the blind hole that clamps the tapping switch nut in the sleeve, on the top of spliced pole was located the distribution transformer live end, the spliced pole top transversely was provided with the action bars of perpendicular to spliced pole. The utility model discloses simple structure, convenient to use use on distribution transformer to revolve its tapping switch's nut and twist the operation, reach the purpose of fastening tapping switch nut, and inconvenient, the maintenance work of operation measures big scheduling problem when having solved processing distribution transformer tapping switch seepage oil, can thoroughly handle distribution transformer tapping switch oil leak phenomenon.
Description
Technical field
The utility model relates to transformer technology field, particularly a kind of auxiliary implement installed for distribution transformer.
Background technology
At present, distrbution network distribution presents a little many, wide feature, and therefore operation maintenance difficulty is larger.Distribution transformer is the important electrical in distrbution network, be used for the alternating voltage (stream) of a certain numerical value to become the identical another kind of frequency or the different voltage (electric current) of several numerical value, the shunting switch that it is arranged is used to the vitals regulating step down side output voltage, therefore to ensure the normal operation of distribution transformer, the intact of shunting switch must be ensured.But distribution transformer is out of doors after longtime running, and its shunting switch place occurs oil seepage phenomena often, this irregularly carries out maintenance process to the shunting switch of distribution transformer with regard to needing.
In the process of traditional maintenance process sub-connecting switch of transformer, all must be out of service by transformer, this just impacts to power supply quality; And because shunting switch is between transformer high-voltage insulator and low pressure insulator, position is comparatively narrow and small, common spanner cannot operate, therefore operating personnel uses screwdriver to withstand on the edges and corners of nut when fastening shunting switch nut usually, tightening operation is carried out with hammer screwdriver, this kind of mode operating difficulties, maintenance time is long, leakage of oil poor processing effect.
Utility model content
The utility model technical issues that need to address are to provide a kind of structure fastening tool of transformer tapping switch simple, easy to use, thoroughly process oil seepage phenomena by carrying out torquing operations to sub-connecting switch of transformer nut.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of distribution transformer shunting switch fastened tools, comprise the sleeve that is sleeved on shunting switch nut and be fixedly installed on sleeve top and with the joint pin of sleeve coaxial line, the blind hole clamping shunting switch nut is provided with in described sleeve, the top of described joint pin is positioned on distribution transformer live end, and joint pin top cross is provided with the action bars perpendicular to joint pin.
Above-mentioned kind of distribution transformer shunting switch fastened tools, described blind hole is ladder blind hole.
Above-mentioned a kind of distribution transformer shunting switch fastened tools, described action bars is screw rod or leading screw, and joint pin top radial direction is provided through the through hole of screw rod or leading screw, is provided with the internal thread of equipped screw rod or leading screw in through hole.
Above-mentioned a kind of distribution transformer shunting switch fastened tools, the two ends of described action bars are all coated with insulating sleeve.
Owing to have employed above technical scheme, acquired by the utility model, technological progress is as follows.
The utility model structure is simple, easy to use, be applied on distribution transformer and torquing operations is carried out to the nut of its shunting switch, reach the object of fastening shunting switch nut, solve the problems such as maintenance operation when processing distribution transformer shunting switch leakage of oil is inconvenient, maintenance load is large, thoroughly can process distribution transformer shunting switch oil leakage phenomenon, decreasing transformer due to shunting switch fault causes the generation of burnout failure, ensure that the safe operation of distribution transformer, produce for electric power safety and improve reliable electric power safeguard.
The action bars that the utility model joint pin top is arranged, convenient working personnel can carry out torquing operations; The operation height of action bars is positioned on transformer live end, and the two ends of action bars are provided with insulating sleeve, can effectively prevent electric shock accidents from occurring, ensure that the safety of operating personnel; Adopt said structure, the utility model can be made to use under distribution transformer electriferous state, improve power supply quality.Because the sub-connecting switch of transformer nut specification on current power circuit is nearly all between 51.5-52.5mm, the utility model carries for convenience of operating personnel, blind hole in sleeve pipe is set to the different shoulder hole of diameter, such operating personnel only carries the shunting switch nut use that a the utility model can meet different size on different model, capacity transformer, improve the utility model versatility, alleviate operating personnel's labour intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1. sleeve, 2. ladder blind hole, 3. joint pin, 4. action bars, 5. insulating sleeve.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
A kind of distribution transformer shunting switch fastened tools, as shown in Figure 1, comprise sleeve 1, joint pin 3 and action bars 4, joint pin 3 is arranged on sleeve its structure, and action bars is arranged on joint pin top.
Blind hole is provided with, for clamping the nut of distribution transformer shunting switch in sleeve 1.In the present embodiment, blind hole is ladder blind hole 2, with the user demand of the shunting switch nut of satisfied different different size.
Joint pin 3 is fixedly installed on sleeve top, and with sleeve coaxial line, during convenient working can in sleeve and sleeve shunting switch nut force.
Action bars 4 is horizontally installed on the top of joint pin, and arranges perpendicular to joint pin.For ensureing operating personnel's handling safety, the top of joint pin is positioned on distribution transformer live end, even if action bars is positioned at the top of transformer live end; In addition, also insulating sleeve 5 is all coated with at the two ends of action bars 4.
In the utility model, carry for convenience, action bars can adopt screw rod or leading screw, and the top radial direction of joint pin is provided through the through hole of screw rod or leading screw, is provided with the internal thread of equipped screw rod or leading screw in through hole.
When the utility model uses, first by the through hole of action bars through joint pin top, the insulating sleeve of hand-held operation bar, is inserted in sleeve on the nut of shunting switch, until shunting switch nut is installed in the ladder blind hole of suitable diameter; Then the nut of shunting switch can be tightened by rotation process bar.After operation completes, action bars is disassembled from joint pin, be convenient for carrying.
