Description

A kind of high voltage power cable rubber-like transition joint erecting device

Technical field

The utility model belongs to HV cable accessories mounting technique field, relates to a kind of high voltage power cable rubber-like transition joint erecting device.

Background technology

The transition joint of high voltage power cable rubber-like has safe and reliable, install simple, superiority such as practicality, but this joint must rely on caoutchouc elasticity to hold the effect of cable main competence exertion tightly, and the face that the joint inner chamber contacts with cable is bigger, be easy in the installation process form vacuum and can't move, this installs to cable and brings certain difficulty, when 110kV power cable is in the past installed, employing is manually led chain and by force joint is drawn in cable, or adopt predilation to add the method for stay tube, these methods waste time and energy, and also cause damage to stay accident potential to cable main and joint easily.Existing a kind of on the market in recent years than advanced electric cable accessories installation method and device, for example Chinese patent application number is 200410022854.6 disclosed " rubber-like electric cable fitting installation method and devices thereof ", this method and device can make high voltage power cable terminal quick for installation, stay impression, pull and scratch etc. can not for the cable main part, but this method and device only are suitable for the installation of power cable terminal, are not suitable for the installation of power cable transition joint.

Summary of the invention

The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of high voltage power cable rubber-like transition joint erecting device is provided, and mainly is applicable to the installation of 110kV power cable transition joint.

The technical solution of the utility model is, a kind of high voltage power cable rubber-like transition joint erecting device, form by the base 1 that has conulite, Metallic rod 2, a pair of Hough cover 3 that has sealing ring and an air-filled pore, Hough cover 4, baffle plate 5, pin 6, two metal anchor ears 7, the compressed gas source 8 that has switch and seal tubes 9, wherein compressed gas source adopts pure nitrogen, and Hough cover and base all are that polytetrafluoroethylmaterial material is made.

The above-mentioned base 1 that has conulite, its with surface that cone is connected on plural groove 10 is arranged.

Owing to adopt the utility model, make the installation of high voltage power cable rubber-like transition joint time saving and energy saving, improved installation effectiveness greatly, the work of being inserted in of generally finishing a cover transition joint only needs the time of a few minutes, ratio cover ETL estimated time of loading in the past shortens greatly, and operation is simple and reliable, is specially adapted to the installation of 110kV power cable.

Description of drawings

Below in conjunction with accompanying drawing the present invention is described in further details.

Fig. 1 is that Hough cover of the present utility model is inserted in the structural representation of transition joint;

Fig. 2 is the on-the-spot schematic diagram that uses of the utility model.

Embodiment

In Fig. 1, transition joint is before being inserted in cable, adopt the Hough cover to be inserted in the method for transition joint, two pairs of Hough covers are inserted in respectively in the inner chamber of transition joint two ends, at first on the base 1 that conulite is arranged, a Metallic rod 2 of being longer than transition joint 12 is fixed with cone, have on the Metallic rod 2 and much fasten hole 11, the cone external diameter is slightly less than Hough cover internal diameter, the a pair of Hough cover 3 that has a sealing ring is enclosed within cone base and fixes with screw, and the part that will insert transition joint on Hough cover 3 is smeared lubricating grease, again transition joint 12 is enclosed within on Metallic rod 2 and the Hough cover 3,, inserts fastening in the hole 11 on the adjacent baffle plate 5 with pin 6 contacting in the baffle plate 5 insertion Metallic rod 2 and with the other end of joint 12, with the fixing position of transition joint 12, with stainless steel metal anchor ear 7 Hough cover 3 and transition joint 12 are clamped then; Take off pin 6 and baffle plate 5 subsequently, adopt identical method to install and fastening Hough cover 4 at transition joint 12 other ends again.On the above-mentioned base 1 that has a conulite, and on the surface that cone is connected four grooves 10 are arranged, take out the transition joint that has the Hough cover with convenient.

In Fig. 2, when on-the-spot 110KV power cable transition joint was installed, certain depth on cable 13 main insulations was inserted in the transition joint 12 that two ends is had the Hough cover, and the end Hough cover 3 that wherein is inserted in earlier has sealing ring and air-filled pore; The compressed gas source 8 that will have switch docks by the pore that is connected that seal tube 9 and transition joint 12 1 end Houghs overlap on 3; Open gas source switch, feed high pressure nitrogen at transition joint 12 inner chambers and cable 13 main insulations surface, owing to press very tightly between sealing ring in the Hough cover 3 and the cable 13, gas can only be gone out from the other end, between transition joint 12 inner chambers and cable 13 main insulations, form the high pressure gas mould like this, promote transition joint 12 simultaneously and slide on cable 13, move to the termination of cable 13, promptly the precalculated position stops inflation; After treating that the 13 core crimping of two sections cables dispose, restart inflation, and oppositely promote transition joint 12, move to the precalculated position and stop inflation, the precalculated position promptly guarantees the middle of cable crimping position in transition joint, unload two pairs of tool devices such as Hough cover, transition joint 12 is that elasticity is held tightly on cable 13 main bodys, and the work of transition joint suit is promptly finished.

Claims (2)

1, a kind of high voltage power cable rubber-like transition joint erecting device, it is characterized in that: form by the base that has conulite (1), Metallic rod (2), a pair of Hough cover (3), Hough cover (4), baffle plate (5), pin (6), two metal anchor ears (7), the compressed gas source (8) that has switch and the seal tube (9) that has sealing ring and air-filled pore, wherein compressed gas source adopts pure nitrogen, and Hough cover and base all are that polytetrafluoroethylmaterial material is made.
