Abstract
The utility model relates to a kind of 110kV cable intermediate joint; comprise tube connector, the integral prefabricated rubber insulators of the equal gland of tube connector outside, all gland outside, integral prefabricated rubber insulators outside copper containment vessel, be filled in insulating cement between copper containment vessel and integral prefabricated rubber insulators, integrally formed ground connection connecting leg and earthing rod outside copper containment vessel; described copper containment vessel is structure as a whole; be coated with at copper containment vessel outer surface the PP insulation material layer that thickness is 6mm, inside copper containment vessel, be coated with one deck pyrocondensation insulated tube.Show through a large amount of water test for a long time; 110kV transition joint of the present utility model comparatively existing product is compared; there is more excellent waterproof sealing performance and decay resistance, the requirement of safe and stable operation under long-term Soaking environment can be met when the outer containment vessel of not equipped with glass steel completely.
Description
Technical field
The utility model belongs to power cable technical field, particularly a kind of 110kV cable intermediate joint.
Background technology
The structure of current 110kV transition joint as shown in Figure 1, forms primarily of insulating cement 4, earth terminal 3, earth terminal 2 and wrapped sealing 1 in tube connector 7, all gland 8, integral prefabricated rubber insulators 9, copper containment vessel 5, epoxy insulation circle 6, copper containment vessel.Copper containment vessel plays electrical connection effect on the one hand, is communicated with by two ends cable metal sheath; Mainly bear mechanical protection, water-tight protective effect on the other hand; guarantee inner adapter body not by ectocine; in current product, epoxy insulation circle and copper containment vessel need be assembled at the scene; sometimes because the carelessness of installation personnel makes insulating cement in copper containment vessel fully not fill, the hydraulic performance decline of epoxy insulation circle two ends copper shell withstand shock voltage is caused.Copper containment vessel outer surface is also coated with one deck epoxy resin insulation material simultaneously, guarantees that copper containment vessel is isolated with extraneous insulation.When reality uses; as the requirement of safe and stable operation under long-term Soaking environment need be met; also need install outer containment vessel additional in transition joint outside and in housing casting insulated waterproof gasket cement; not only cost increase is larger for this scheme; also because waterproof gasket cement is often two component; just to pour into after need stirring at the scene in outer containment vessel and to solidify; not only increase the labour intensity of installation personnel; and often cause waterproof sealing performance to decline because stirring uneven, inevitably can cause the pollution to environment in installation process simultaneously.In addition because containment vessel volume is comparatively large, virtually add the space of cable tunnel shared by transition joint (or cable trough).Because the installing space in cable tunnel, cable trough and joint well is limited, therefore need to be optimized and to improve the structure of existing 110kV transition joint product, fully to meet the requirement in market.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of 110kV cable intermediate joint.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of 110kV cable intermediate joint, comprise the tube connector of connection two end cable, the equal gland of tube connector outside, cover the integral prefabricated rubber insulators of equal gland outside, be wrapped in the copper containment vessel of integral prefabricated rubber insulators outside, be filled in the insulating cement between copper containment vessel and integral prefabricated rubber insulators, integrally formed two ground connection connecting legs and be arranged on the earthing rod of ground connection connecting leg inside outside copper containment vessel, described copper containment vessel is structure as a whole, the PP insulation material layer that thickness is 6mm is coated with at copper containment vessel outer surface, one deck pyrocondensation insulated tube is coated with inside copper containment vessel.
And described two ground connection connecting legs are placed in the side of copper containment vessel, two ground connection connecting legs are mutually 60 ° of angles.
And described earthing rod is annular ground rod structure.
Advantage of the present utility model and good effect are:
Show through a large amount of water test for a long time; 110kV transition joint of the present utility model comparatively existing product is compared; there is more excellent waterproof sealing performance and decay resistance, the requirement of safe and stable operation under long-term Soaking environment can be met when the outer containment vessel of not equipped with glass steel completely.
Accompanying drawing explanation
Fig. 1 is the structural representation of current 110kV transition joint;
Fig. 2 is the structural representation of the utility model 110kV transition joint;
Fig. 3 is the structural representation of two ground connection connecting legs in the utility model.
Embodiment
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of 110kV cable intermediate joint, as shown in Figure 2, comprise the tube connector 6 of connection two end cable, the equal gland 7 of tube connector outside, cover the integral prefabricated rubber insulators 5 of equal gland outside, be wrapped in the copper containment vessel 4 of integral prefabricated rubber insulators outside, be filled in the insulating cement 3 between copper containment vessel and integral prefabricated rubber insulators, integrally formed two ground connection connecting legs 1 and be arranged on the earthing rod 2 of ground connection connecting leg inside outside copper containment vessel, innovative point of the present utility model is, described copper containment vessel is structure as a whole, improve the performance of withstand shock voltage, thickness is had to be the PP insulation material layer 9 of 6mm in copper containment vessel surface coverage, strengthen overall water resistance, inside copper containment vessel, be coated with one deck pyrocondensation insulated tube 8 isolate, effectively enhance insulation and the water-tight performance of cable intermediate joint inside.
In concrete enforcement of the present utility model, as shown in Figure 3, described two ground connection connecting legs are placed in the side of copper containment vessel, and two ground connection connecting legs are mutually 60 ° of angles, for installing the convenience brought spatially.
In concrete enforcement of the present utility model, described earthing rod changes original square earthing block structure into annular ground rod structure, to facilitate follow-up wrapped and encapsulation process.
