Technical field
The utility model belongs to line protection device technical field, relates more specifically to a kind of compound tense and insulate
Son.
Background technology
Strain insulator is mainly used in electric line, plays insulating effect in pole guy or tensioning conducting wire, draws
Tight insulator needs to bear the vertical load of conducting wire, horizontal loading and wire tension, it is therefore necessary to have good insulation performance and
Enough mechanical performances.
Traditional strain insulator, production technology is complicated, installation is inconvenient, moreover, in the prolonged course of work and drawing
Tightly the bonding strength between insulator and conducting wire can reduce, it is impossible to ensure conducting wire enough grips, consequently, it is possible to causing thing
Therefore influence power grid normal operation.
The china national practical new-type patent of 201720385280 .1 of Patent No. discloses a kind of strain insulator, well
Solve problem above, but the connector of the two of the device relative spacing settings is fixedly connected respectively with insulation mandrel, this
Kind of connected structure set-up mode, although so that the insulation performance of strain insulator is more preferable, being not sufficiently stable property of stress intensity compared with
Difference, it is easy to external force is transferred to composite insulation layer, lead to the fracture of composite insulation layer inner wall, particularly the device waterproof effect
Bad, water can enter insulating body because of capillary phenomenon, cause to leak electricity；And if winter, water that inner wall enters by capillary phenomenon
Divide after freezing, the damage of composite insulation layer can be accelerated.
Invention content
To solve the above problems, overcome the deficiencies in the prior art, it is steady that the utility model provides a kind of good insulating structure
Fixed good and good water-proof effect compound strain insulator, can effectively solve unbalance stress and external force is transferred to compound inslation
Layer, the problem of leading to the fracture of composite insulation layer inner wall and bad waterproof effect.
The utility model solve above-mentioned technical problem specific technical solution be：The compound strain insulator, including
Insulating body, composite insulation layer, draw ring and connection ring, it is characterised in that the insulating body is arranged to rectangular parallelepiped structure, insulation
The center of the end face of ontology is horizontally disposed fluted, and the draw ring and connection ring are all provided with being set to U-shaped, and the connection ring is set
Be set to two, connection ring is reversely arranged in a crossed manner with vertical direction in the horizontal direction respectively, the connection ring in a manner of engaging with
Fit depressions, the external casting mode of the insulating body are provided with composite insulation layer, are set outside the composite insulation layer
There are full skirt and waterproof construction, the waterproof construction is arranged to conical structure, and waterproof construction is provided centrally with through-hole, the through-hole
It is matched with connection ring, the draw ring side is provided with clamping ring, and the opposite side of draw ring is by bolted connection with connecting
Ring is fixedly linked.
Further, the insulating body material is using ceramics.
Further, the radius more than connection ring of the depth of the groove.
Further, the composite insulation layer, full skirt and waterproof construction are an integral structure form.
Further, the composite insulation layer, full skirt and waterproof construction material use epoxy resin.
The beneficial effects of the utility model are：The connection ring is reversely intersected respectively with vertical direction in the horizontal direction to be set
It puts in a manner of engaging and the fit depressions of insulating body, while insulating properties is ensured, significantly increases the steady of structure
It is qualitative, the internal break of composite insulation layer caused by avoiding stress concentration；The waterproof construction is effectively prevented because of capillary
Phenomenon water enters insulating body, causes to leak electricity or the problem of composite insulation layer is caused to damage of freezing.
