Abstract
The invention discloses a tester for moving contact and fixed contact insertion depths of a KYZ-10/35 type breaker. The tester comprises a depth measurement column, a fixed contact hole locating seat is arranged in the middle of the depth measurement column, and the depth measurement column is in axial sliding fit with the fixed contact hole locating seat. The moving contact and fixed contact insertion depths of the breaker can be measured through the tester so as to detect whether contact resistance of a moving contact and a fixed contact meets the regulations and requirements, and accordingly premature aging and even burndown faults of the breaker which are caused by over large contact resistance caused by insufficiency of the moving contact and fixed contact insertion depths of the breaker is avoided. The tester has the advantages of being small in size, light in weight and convenient to carry and measuring the depths accurately and the like.
Description
Technical field
The present invention relates to a kind of KYZ-10/35 type isolating switch dynamic/static contact insertion depth tester.
Background technology
Along with the electric utility development, the 10-35kV armored equipment adopts handcart type breaker, has become today and even the development trend in a period from now on.In actual motion, because the dynamic and static contact insertion depth of isolating switch not enough (not meeting designing requirement), it is overheated to cause between the dynamic and static contact of isolating switch, burns the isolating switch event and occurs repeatedly.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of KYZ-10/35 type isolating switch dynamic/static contact insertion depth tester, and it has, and volume is little, lightweight, the characteristics such as be easy to carry.The present invention can measure the insertion depth of the dynamic and static contact of isolating switch, to detect the whether requirement up to specification of its contact resistance, thereby avoid since the dynamic and static contact insertion depth of isolating switch deficiency cause excessive because of contact resistance, cause the isolating switch premature aging even burn fault.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Comprise the depth survey post, the middle part of depth survey post is provided with static contact hole positioning seat, axially is slidingly matched between depth survey post and static contact hole positioning seat.
The present invention further improves and is:
The two ends of depth survey post respectively are provided with first torus, connect by first axis of guide between two the first torus, and static contact hole positioning seat is provided with the first corresponding pilot hole.
Static contact hole location seat structure is: two ends respectively are provided with second torus, connect by second axis of guide between two the second torus, and the first torus of depth survey post outer end is provided with the second corresponding pilot hole.
Depth survey post and the static contact hole applied material of positioning seat are unsaturated polyester resin.
The beneficial effect that adopts technique scheme to produce is:
The present invention can measure the insertion depth of the dynamic and static contact of isolating switch, to detect the whether requirement up to specification of its contact resistance, thereby avoid since the dynamic and static contact insertion depth of isolating switch deficiency cause excessive because of contact resistance, cause the isolating switch premature aging even burn fault.Comprise the depth survey post, the middle part of depth survey post is provided with static contact hole positioning seat, axially is slidingly matched between depth survey post and static contact hole positioning seat.Static contact hole positioning seat can make this depth test device relative with the static contact hole site fixing, sets up measuring basis, so that the Measurement accuracy of depth survey post.The two ends of depth survey post respectively are provided with first torus, connect by first axis of guide between two the first torus, and static contact hole positioning seat is provided with the first corresponding pilot hole.Static contact hole positioning seat is behind static contact hole upper axial location, and the depth survey post has reached the measurement purpose by axially being displaced downwardly to bottom, static contact hole in first pilot hole of its first axis of guide on the positioning seat of static contact hole.Static contact hole location seat structure is: two ends respectively are provided with second torus, connect by second axis of guide between two the second torus, and the first torus of depth survey post outer end is provided with the second corresponding pilot hole.Be convenient to axial location is carried out in the static contact hole, to improve measuring accuracy.Depth survey post and the static contact hole applied material of positioning seat are unsaturated polyester resin.Good insulation preformance, sturdy and durable, lightweight, be easy to carry.
Therefore it has the characteristics such as volume is little, lightweight, measurement is accurate, be easy to carry, and is service kit very practical in the electric power overhaul industry.
Description of drawings
Fig. 1 is structural representation of the present invention.
In the accompanying drawings: 1, the first torus; 2, first axis of guide; 3, the second torus; 4, second axis of guide; 5, the second pilot hole; 6, the first pilot hole.
Embodiment
By embodiment shown in Figure 1 as can be known, comprise the depth survey post, the middle part of depth survey post is provided with static contact hole positioning seat, axially is slidingly matched between depth survey post and static contact hole positioning seat.Static contact hole positioning seat can make this depth test device relative with the static contact hole site fixing, sets up measuring basis, so that the Measurement accuracy of depth survey post.
The two ends of depth survey post respectively are provided with between 1, two the first torus 1 of first torus and connect by first axis of guide 2, and static contact hole positioning seat is provided with the first corresponding pilot hole 6.Static contact hole positioning seat is behind static contact hole upper axial location, and the depth survey post has reached the measurement purpose by axially being displaced downwardly to bottom, static contact hole in first pilot hole of its first axis of guide on the positioning seat of static contact hole.
Static contact hole location seat structure is: two ends respectively are provided with between 3, two the second torus 3 of second torus and connect by second axis of guide 4, and the first torus 1 of depth survey post outer end is provided with the second corresponding pilot hole 5.Be convenient to axial location is carried out in the static contact hole, to improve measuring accuracy.
Depth survey post and the static contact hole applied material of positioning seat are unsaturated polyester resin.Good insulation preformance, sturdy and durable, lightweight, be easy to carry.
The purpose of static contact hole positioning seat is to make that this depth test device is quiet to carry out axial location to contact apertures, finds reference point, in order to measure, can be various ways, for example, and with the suitable decussate texture in static contact hole.
Using method:
Static contact hole positioning seat inserts top, static contact hole, after carrying out axial location, the depth survey post is by axially being displaced downwardly to bottom, static contact hole in first pilot hole of its first axis of guide on the positioning seat of static contact hole, measure the static contact hole depth according to the first torus and the second toric shift length, take out afterwards the depth test device, with breaker closing, measure again the length that moving contact is positioned at outside, static contact hole, because its total length is known, can calculate the insertion depth of moving contact of breaker.
