As depicted in figs. 1 and 2, it is attached to provide a kind of hv cable termination head shrinkage cable with sheetlike temperature indicator for the utility model
Part is set with several shrinkage insulation tubes 2 including the shrinkage fingerstall 1 being sleeved on cable on shrinkage fingerstall 1, shrinkage insulation tube 2
Upper end is set with cold-shrinkable terminal 3, and terminal 4, shrinkage fingerstall 1, shrinkage insulation tube 2 and terminal 4 are socketed on cold-shrinkable terminal 3
Lateral wall on be provided with the sheetlike temperature indicators 6 of several side Pastings.Sheetlike temperature indicator 6 is similar pressure-sensitive adhesive trade mark paper, by the back side
Adhesive sticker pastes measured point, and when measured point temperature is higher than discoloration rated temperature, sheetlike temperature indicator 6 is black and irreversible by leucismus.It is preferred that
, several sheetlike temperature indicators 6 go up equidistant arrangement along its length on shrinkage fingerstall 1 and shrinkage insulation tube 2.Convenient for further division event
Hinder the specific location of point, and keeps the color change of sheetlike temperature indicator 6 more eye-catching.Wherein, the length direction is contracting insulation tube 2
Length direction, the i.e. vertical direction of Fig. 1.
Due to cold-shrink cable terminal in the raw under, exposing to the weather drenches with rain, and sheetlike temperature indicator 6 is for a long time in such circumstances
Performance can decline obviously.The sealing protection cover 5 for protecting sheetlike temperature indicator 6 is mounted in the top of several sheetlike temperature indicators 6.Sealing protection
Cover 5 includes shield ontology 501, and the surface of shield ontology 501 is arc, and is glass material, has transparent effect.Sheetlike temperature indicator 6

The lateral wall of shrinkage fingerstall 1, shrinkage insulation tube 2 and terminal 4.Outside due to shrinkage fingerstall 1, shrinkage insulation tube 2 and terminal 4
Sidewall surfaces are uneven, if shield ontology 501 is directly mounted on its surface, sealing effect is bad.Fusible patch 502 can be with
The face seal of cold-shrink cable terminal contacts, and pastes merge with it under certain condition, and final to solidify, similar is fusible
Patch 502 can be glass cement.
Some cold-shrink cable terminal installation sites are higher, the inconvenient discoloration feelings for checking sheetlike temperature indicator 6 in time of operation maintenance personnel
Therefore condition is provided with convex lens magnifying glass 503, convex lens magnifying glass 503 in the inside of the shield ontology 501 of 6 corresponding position of sheetlike temperature indicator
Positioned at 6 front of sheetlike temperature indicator.Through convex lens magnifying glass 503 can from the color change for watching amplified sheetlike temperature indicator 6 at a distance, and
When cold-shrink cable terminal is safeguarded.
Specifically, shield ontology 501 includes transparent arc display surface 504, the inside of arc display surface 504 is surrounded by
Arc is mounted on bottom surface of the arc around retaining wall 505 around retaining wall 505, fusible patch 502, and convex lens magnifying glass 503 is located at arc ring
In the cavity that retaining wall 505 and arc display surface 504 are formed.
The utility model is provided in several key positions of cold-shrink cable terminal to be reached threshold temperature and can change colour
The sheetlike temperature indicator 6 of early warning, and be mounted with to prevent the sealing protection cover 5 of external environment destruction sheetlike temperature indicator on the surface of sheetlike temperature indicator 6, pass through
Convex lens magnifying glass 503 on sealing protection cover can also understand the discoloration of sheetlike temperature indicator 6 at a distance, improve O&M efficiency, and
When control failure.
The above, above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although ginseng
The utility model is described in detail according to previous embodiment, those skilled in the art should understand that: it is still
It is possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced
It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
