Description

Technical Field

[0001] The invention relates to a rubber sleeve for connecting high-voltage insulators, belonging to the technical field of reactors. Background Art

[0002] With the development of my country's power industry, more and more substations use power cables for incoming and outgoing lines. The capacitive current generated by the cable will affect the quality of electric energy, so more and more substations use reactors (such as air-core reactors) to compensate for the capacitive current generated by the cable to improve the quality of electric energy. During use, the insulators used in the reactor may have unplanned discharge phenomena, which may be due to the dirt, moisture and cracks on the surface of the insulator; this discharge will not only affect the service life of the equipment, but also bring safety hazards to the staff. In view of the above-mentioned discharge phenomenon, the insulators used at this stage need to play the role of isolation and support, but at the same time, a rubber sleeve is added to the outside of the insulator to improve the insulation performance.

[0003] However, the above-mentioned method of adding rubber sleeves also has certain shortcomings. In order to ensure the supporting effect, the insulator is provided with different connection structures. The existing rubber sleeves cannot fit tightly with the insulators, so the effect of improving the discharge problem is limited; at the same time, since the new structure is added to the insulator, it does not play a stable supporting effect, and even affects the maintenance and replacement of the insulator. Summary of the invention

[0004] Therefore, an object of the present invention is to provide a rubber sleeve for connecting high-voltage insulators to ensure the insulation and supporting effects of the insulators.

[0005] In order to achieve the above object, the present invention provides a rubber sleeve for high voltage insulator connection, comprising:

[0006] A sealing portion, arranged on the inner side of the connecting rubber sleeve and attached to the surface of the insulator;

[0007] An outer portion, which is an integral structure with the sealing portion;

[0008] The reinforcing portion is disposed between the sealing portion and the outer portion and is used to support the sealing portion and the outer portion.

[0009] Furthermore, the reinforcement part is a metal mesh and / or a fiber cloth.

[0010] Furthermore, the connecting rubber sleeve is made of silicone rubber.

[0011] Furthermore, the connector rubber sleeve is added with a fixing portion for fixing the connector rubber sleeve and the insulator.

[0012] Furthermore, an adhesive layer is included between the sealing portion and the insulator.

[0013] Furthermore, the sealing portion is provided with a thickening layer at the edge.

[0014] Furthermore, the connecting rubber sleeve is in a ring shape.

[0015] Furthermore, the sealing portion is provided with a plurality of sealing grooves.

[0016] By adopting the above technical scheme, a connecting rubber sleeve for high-voltage insulators provided in an embodiment of the present invention is divided into a sealing part and a reinforcement part, and the reinforcement part is added between the two, so as to improve the mechanical strength and durability of the connecting rubber sleeve. In the process of connecting / fixing with the connecting rubber sleeve, the sealing part forms a sealing surface with the surface of the insulator, so as to effectively overcome the discharge and / or short circuit of the insulator. At the same time, due to the addition of the reinforcement part, the stable support of the insulator can be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described in detail below through the accompanying drawings and specific implementation methods. The dirt, moisture and cracks on the surface of the existing reactor insulators lead to discharge. The rubber sleeve added to address this situation cannot fit tightly with the insulator, and thus the expected improvement effect on the discharge problem cannot be achieved. Although a protective mechanism is added, the supporting effect of the insulator is not improved.

[0021] Example

[0022] like Figure 1 and Figure 2 As shown, the present invention provides a rubber sleeve for connecting high-voltage insulators, comprising:

[0023] The sealing part 1 is arranged on the inner side of the connecting rubber sleeve and is attached to the surface of the insulator; the shapes of the sealing part 1 and the corresponding parts of the insulator should match each other to ensure a close fit and adapt to slight deformation and displacement of the connection between the two.

[0024] The materials used are preferably highly elastic materials to meet the needs of bending and stretching, and also need to take into account weather resistance, chemical corrosion resistance, and materials with good bonding properties, including but not limited to silicone rubber, which can have good compatibility with the material of the insulator to avoid chemical reactions or physical wear during long-term use. The above materials are specially treated to improve their weather resistance, corrosion resistance and aging resistance; the special treatment can be the addition of antioxidants, UV inhibitors or other chemical additives;

[0025] The sealing part 1 can be fitted with the insulator in the form of a sealing lip or a sealing surface, wherein the sealing lip is essentially a thickened layer 4 provided at the edge of the sealing part 1 .

[0026] In order to achieve the desired effect of the bonding, an adhesive layer may be included between the sealing part 1 and the insulator. The above adhesive layer may be solid or colloid, and the sealing part 1 may be provided with a plurality of sealing grooves for accommodating the above colloid, and the sealing grooves may improve the bonding degree between the sealing part 1 and the insulator.

[0027] The outer portion 2 is an integral structure with the sealing portion 1;

[0028] The reinforcing part is arranged between the sealing part 1 and the outer part 2, and is used to support the sealing part 1 and the outer part 2. The reinforcing part can be made of metal mesh and / or fiber cloth. In an alternative embodiment, the reinforcing part can be arranged between the sealing part 1 and the insulator.

[0029] It should be noted that the connecting rubber sleeve is added with a fixing part 3 for fixing the connecting rubber sleeve and the insulator. The fixing part 3 can be a component with a fixing function such as a clip, a bolt, a buckle, etc., wherein the size of the fixing part 3 needs to be pre-set according to the size of the connecting rubber sleeve and the insulator. The above-mentioned connecting rubber sleeve can be set to be annular to improve the fixing effect of the fixing part 3.

[0030] The design of the above-mentioned connecting rubber sleeve meets the requirements of relevant national or international standards to ensure its quality and reliability; the standards may include requirements for electrical performance, mechanical performance, sealing performance, etc. It should be added here that in the connection method between the above-mentioned connecting rubber sleeve and the insulator, a margin of 3-5mm should be left from the insulator section for easy installation. A connecting rubber sleeve for high-voltage insulators provided in an embodiment of the present invention is divided into a sealing part and a reinforcement part, and a reinforcement part is added between the two, so as to improve the mechanical strength and durability of the connecting rubber sleeve. In the process of connecting / fixing with the connecting rubber sleeve, the sealing part forms a sealing surface with the surface of the insulator, thereby effectively overcoming the discharge and / or short circuit of the insulator. At the same time, due to the addition of the reinforcement part, the stable support of the insulator can be guaranteed. Obviously, the above-mentioned embodiments are only examples for clear explanation, and are not limitations on the implementation methods. For ordinary technicians in the field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. And the obvious changes or modifications derived from this are still within the scope of protection of the invention.
