Abstract
The utility model discloses an auxiliary hand for testing secondary circuit voltage drop of a voltage transformer. The top part of a foldable support I, the top part of a foldable support II and the top part of a foldable support III are fixed through a fastening connecting plate, and the bottom parts of the foldable supports incline outwards along different directions to form a rectangular support. The bottom part of a fixed support is inserted in the fastening connecting plate, the top part is fixed with the middle part of a telescopic bracket through a pointer screw, the front part of the telescopic bracket is fixedly provided with test wire clamp with the angle being adjustable, and the rear part of the telescopic bracket is fixedly provided with uniformly distributed test wire sleeves. The auxiliary hand disclosed by the utility model overcomes influences that the clamp is caused to fall off because of the gravity of a wire itself and that the contact resistance is increased, thereby increasing the test precision, and solving potential safety hazards caused by insecure fixation of the clamp.
Description
Technical field
The utility model relates to a kind of device for Secondary Circuit of Potential Transformer pressure fall-off test.
Background technology
According to the regulation of existing electric company electric energy measuring management way, need to regularly carry out voltage drop test, owing to there is no the strong point at experiment line clamping connection in measuring box or the table tail end period of the day from 11 p.m. to 1 a.m, easily producing wire clamp moves, cause wire clamp to come off or contact not firmly, causing contact resistance to increase, affecting test accuracy, when serious, produce the short circuit of meeting each other, cause staff to be injured operational outfit impaired.
Summary of the invention
The problems referred to above that exist for solving prior art, the utility model provides a kind of Secondary Circuit of Potential Transformer pressure fall-off test nondominant hand, and its technical scheme of taking is:
Comprise scalable bracket, and by Collapsible rack I, Collapsible rack II, the supporting structure that Collapsible rack III and fixed support form, the top of Collapsible rack I, the top of Collapsible rack II, the top of Collapsible rack III fixes by fastening connecting plate, their bottom forms Tripod along different directions flare, support bracket fastened bottom is plugged in fastening connecting plate, its top fixes by the middle part of pointer screw and scalable bracket, the front portion of scalable bracket is fixed with the adjustable p-wire wire clamp of angle, the rear portion of scalable bracket is fixed with equally distributed p-wire sleeve pipe.
Supporting structure of the present utility model can carry out folding retractable adjusting, simple flexibly, is easy to carry; Before and after the bracket of extension type, shrink, thereby the distance of adjusting and terminal box can adapt to the requirement of site space, installs dedicated testing wire wire clamp additional, better bear the gravity of p-wire simultaneously, make wire clamp and termination contact more reliable; Between fastening connecting plate and fixed support, adopt slot fixed form, fixation, technique is simple; 3 distributed sleeve pipes are set, can support the gravity of bearing p-wire, easy to operate, can not cause damage to p-wire.
The utility model is highly suitable for present Secondary Circuit of Potential Transformer pressure fall-off test, overcome because the gravity of wire self but wire clamp comes off and contact resistance increases impact, thereby increased measuring accuracy, solve the not potential safety hazard of firm generation of wire clamp, greatly improved Social benefit and economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the supporting structure that Collapsible rack I 6, Collapsible rack II 7, Collapsible rack III 8 and fixed support 9 form, the top of the top of the top of folding rack I 6, Collapsible rack II 7, Collapsible rack III 8 fixes by fastening connecting plate 5, their bottom flare forms Tripod, maximum opening angle is 20 °, smooth adjustment between 40-130cm.The bottom of fixed support 9 is plugged in fastening connecting plate 5, the top of fixed support 9 fixes by pointer screw 4 and the middle part of scalable bracket 1, scalable bracket 1 can shrink front and back, thereby in the scope of 0.6-1.15m, regulate the distance with terminal box, the front portion of scalable bracket 1 is fixed with the adjustable p-wire wire clamp 3 of angle, and the rear portion of scalable bracket 1 is fixed with equally distributed three p-wire sleeve pipes 2.
During actual use, p-wire is fixed on scalable bracket 1, scalable bracket 1 can stretch according to actual needs, p-wire is fixed on terminal box or table tail end by p-wire wire clamp 3, by unclamping, refer to that oncomelania silk 4 can regulate the angle of scalable bracket 1, to select the best angle of test, then according to the height of institute's testing element, regulate the height of fixing rack structure, by above process, guaranteed that p-wire zero comes off and reduces contact resistance, improves measuring accuracy.
