Description

Technical Field

[0001] The invention relates to the field of power cables, and in particular to an ultra-low resistance semi-conductive buffer water-blocking tape. Background Art

[0002] The (ultra) high voltage insulated cable includes, from the core to the outside, a conductor, a conductor shielding layer, an insulating layer, an insulating shielding layer, a buffer layer, a metal sheath, an anti-corrosion layer, and an outer sheath. The buffer layer of the (ultra) high voltage insulated cable is often wrapped with a semi-conductive buffer water-blocking tape material. The buffer layer has semi-conductive properties and plays a role in buffering and weakening the electric field strength. The semi-conductive buffer water-blocking tape can prevent moisture from further diffusing along the longitudinal direction of the cable, thereby playing a longitudinal water-blocking function for the cable. However, the current semi-conductive buffer water-blocking tape is superficial.

[0003] The patent application with announcement number CN106782827A proposed in the prior art greatly reduces the surface resistance and volume resistivity of the semi-conductive buffer water-blocking tape by performing semi-conductive treatment twice or more on at least one substrate of the non-woven fabric I and the non-woven fabric sub; and / or adding a semi-conductive water-absorbing resin with a large particle size to the non-conductive water-absorbing resin;

[0004] Since the particle size of the semi-conductive water-absorbing resin is larger than that of the non-conductive water-absorbing resin, the water-absorbing material in the transition layer I and the transition layer II is mainly the semi-conductive water-absorbing resin connected with the bonding layer I and the bonding layer II. In this way, the semi-conductive material is distributed over a wider range in the thickness direction of the semi-conductive buffer water-blocking tape, thereby reducing the resistance of the product.

[0005] However, the current semi-conductive buffer water-blocking tape can achieve ultra-low resistance by using large-particle semi-conductive water-absorbing resin, but the semi-conductive buffer water-blocking tape is set inside the cable to protect the inner core of the cable. When the cable is damaged, the semi-conductive buffer water-blocking tape is destroyed, which will cause the cable core to be exposed. The damaged semi-conductive buffer water-blocking tape needs to be operated manually using tools, but it cannot protect the cable core by self-repairing when the semi-conductive buffer water-blocking tape is damaged.

[0006] Therefore, it is necessary to provide an ultra-low resistance semi-conductive buffer water-blocking tape to solve the above technical problems. Summary of the invention

[0042] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0043] First embodiment

[0044] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A schematic structural diagram of a first embodiment of an ultra-low resistance semi-conductive buffer water-blocking tape provided by the present invention; Figure 2 for Figure 1 The enlarged schematic diagram of part A is shown. An ultra-low resistance semi-conductive buffer water-blocking tape comprises:

[0045] A water-blocking tape body 1, wherein a non-woven fabric layer 2 is disposed inside the water-blocking tape body 1, a buffer layer 3 is bonded to the surface of the non-woven fabric layer 2 by glue, a repair component 4 is disposed on the surface of the buffer layer 3, and the repair component 4 includes a connecting strip 41, and a plurality of microcapsules 42 are disposed inside the connecting strip 41;

[0046] Multiple water-blocking layers 5 are bonded to the surface of the connecting strip 41 by glue, the surfaces of the multiple water-blocking layers 5 are provided with outer layers 7, and gaps 6 and adhesive strips 8 are respectively provided between the multiple water-blocking layers 5 and the multiple outer layers 7.

[0047] The non-woven fabric layer 2 is made by impregnating the non-woven fabric with a glue containing carbon black, graphite or graphene conductive material. For example, the non-woven fabric is used as the base material and impregnated with an acrylic glue containing uniformly dispersed carbon black. The carbon black can form a conductive path in the glue, making this layer semi-conductive, playing the role of a uniform electric field, and preventing local discharge caused by the concentrated electric field generated during the operation of the cable.

[0048] The buffer layer 3 is made of fluffy cotton. The loose structure of the fluffy cotton gives it good elasticity and buffering properties. It can effectively absorb and disperse energy when the cable is squeezed or stretched by external force, protecting the conductor and insulation layer inside the cable. This layer can be bonded to the inner non-woven fabric layer 2 by a polymer adhesive such as polyvinyl alcohol.

[0049] The material of the microcapsules 42 may be urea-formaldehyde resin or gelatin.

[0050] The plurality of pores 6 are used for filling the conductive glue between the water blocking layer 5 and the outer layer 7 .

[0051] The water-blocking layer 5 can first be laid with a film or fiber mesh made of a high molecular water-absorbing material (such as a highly absorbent resin composed of polyacrylamide or polyacrylic acid salt copolymer), which can absorb a large amount of water and form a gel-like substance to prevent further penetration of water, and then covered with a layer of waterproof polypropylene fiber or polyester fiber fabric on the outside to further block the invasion of water. These materials can be tightly combined by adhesives such as acrylic glue to form an effective water-blocking system. At the same time, graphene water-blocking powder can also be appropriately added to this layer to enhance the overall water-blocking and conductive properties.

[0052] The outer layer 7 is silk cotton cloth, which is soft and has certain water absorption and air permeability, which can make the semi-conductive buffer water-blocking tape have better comfort and flexibility. At the same time, it can also play a certain protective role to prevent external physical damage from affecting internal materials and cables. This layer can also be bonded to the water-blocking layer by an adhesive.

[0053] The adhesive strip 8 is made of adhesive silicone rubber.

[0054] The interior of the microcapsule 42 contains a repair agent, which is urea-formaldehyde resin or gelatin. The outer shell of the microcapsule 42 is stable under normal circumstances. When the material is damaged, the microcapsule 42 ruptures and releases the repair agent. For example, for self-repair of the waterproof function, microcapsules containing waterproofing agents can be added. The microcapsules can be made of urea-formaldehyde resin or gelatin, and their diameter can be between tens of microns and hundreds of microns. When tiny cracks appear on the surface of the material, the cracks extend and cause the microcapsules to rupture, and the waterproofing agent flows out and fills the cracks to restore the water-blocking properties.

[0055] Use of pores 6: When it is necessary to inject repair material into a certain layer, the repair material can reach the damaged part through pores 6. For example, some tiny pores 6 are set in the semi-conductive layer. When the semi-conductive performance decreases, conductive glue for conductive repair can be injected through pores 6 to restore the semi-conductive performance.

[0056] Compared with the related art, the ultra-low resistance semi-conductive buffer water-blocking tape provided by the present invention has the following beneficial effects:

[0057] The present invention provides an ultra-low resistance semi-conductive buffer water-blocking tape, wherein a connecting strip 41 with multiple microcapsules 42 is arranged between a non-woven fabric layer 2 with a buffer layer 3 and multiple water-blocking layers 5. When a main body 1 of the water-blocking tape is damaged, the damaged position can be self-repaired by the damaged microcapsules 42, thereby protecting the cable core.
