Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage cables, in particular to a grounding structure of a high-voltage detachable connector. Background Art

[0002] The detachable connector of high-voltage cable accessories is a completely insulated terminal that connects or disconnects the cable from other equipment, while the shielded detachable connector refers to a detachable connector with a completely shielded outer surface. It is an important component in the high-voltage power transmission and distribution network and is widely used in power equipment such as switch cabinets, ring network cabinets, branch boxes, box-type substations, and offshore wind power. It plays a protective role in the inlet and outlet bushings. There are many voltage level classifications of detachable connectors, such as 8.7 / 15kV, 12 / 20kV, 26 / 35kV, 38 / 66kV, etc. Common types include front plugs and rear plugs; the detachable connector consists of a stress body and a connector body. The connector body (hereinafter referred to as a plug) consists of an inner shield, an insulating layer, and an outer shield (the three-layer structure is made of rubber material and is elastic); the main function of the outer shield is shield grounding. The grounding structure and method affect the long-term reliable operation of the power transmission and distribution equipment. Reliable grounding can ensure that the product surface is at zero potential, that is, a safe and reliable state. If a product discharge accident occurs, reliable outer shield grounding can conduct the current to the earth to avoid the accumulation of discharge charge, heating, and then ablation and combustion accidents;

[0003] The existing grounding methods are to connect the ground wire by compressing the conductive shielding layer of the rubber product and the rubber conductive shielding wiring ear with a metal gasket or a metal clamp. The type is external single-point grounding. This grounding structure is affected by many installation and environmental factors, so power failure accidents caused by poor grounding often occur. Utility Model Content

[0004] The utility model provides a grounding structure of a high-voltage detachable connector, the main purpose of which is to solve the problem of power failure accidents caused by poor grounding.

[0005] To achieve the above object, the utility model provides a grounding structure of a high-voltage detachable connector, comprising:

[0006] A connector body, the connector body comprising a connector outer shield and a connector inner shield;

[0007] The outer shield of the connector is a hollow "T"-shaped structure, and the outer shield of the connector with a hollow structure facilitates the insertion of the inner shield of the connector;

[0008] The inner size of the vertical slot of the connector outer shield matches the size of the connector inner shield, and the connector inner shield is plugged and arranged inside the vertical slot of the connector outer shield;

[0009] The connector inner shield is plugged and arranged at the inner top of the connector outer shield, and an insulating material is injected between the connector outer shield and the connector inner shield, and the connector outer shield is fixedly connected to the connector inner shield through the insulating material, thereby realizing the molding of the connector body;

[0010] The surface of the outer shield of the connector is usually leather grained or sandblasted;

[0011] The inner surface of the connector inner shield is usually smooth, and the outer surface is sandblasted to facilitate bonding and molding with the connector outer shield;

[0012] A prefabricated composite grounding clamp is fixedly arranged on the outer surface of the connector outer shield, and the prefabricated composite grounding clamp is in an annular structure;

[0013] The prefabricated composite grounding clamp is located at a position where the connector outer shielding vertical rod is close to the connector outer shielding transverse rod;

[0014] The outer surface of the connector outer shield is sandblasted at the position corresponding to the prefabricated composite grounding clamp;

[0015] The surface of the connector outer shield is sandblasted to facilitate molding and bonding with the prefabricated composite grounding clamp;

[0016] The position of the surface sandblasting is between 10 mm and the transverse rod of the connector outer shield;

[0017] The reason for selecting this place for surface sandblasting is that the hardness of the connection between the horizontal rod and the vertical rod is relatively high, and it is not easy to deform when installing the prefabricated composite grounding clamp;

[0018] The width of the surface sandblasting treatment is 10-20 mm, which needs to be 5-10 mm larger than the width of the prefabricated composite grounding clamp, so as to facilitate the installation of the prefabricated composite grounding clamp;

[0019] The prefabricated composite grounding clamp comprises semi-conductive silicone rubber, and the semi-conductive silicone rubber is provided in two groups, and the two groups of semi-conductive silicone rubber are distributed in parallel up and down;

[0020] A thick copper mesh is arranged between the two groups of the semi-conductive silicone rubber, and the two groups of the semi-conductive silicone rubber are connected through the thick copper mesh;

[0021] The thick copper mesh is connected by injection molding of two groups of semi-conductive silicone rubber;

[0022] A first thick copper gasket is fixedly disposed at the center position of both ends of the semi-conductive silicone rubber of the lower layer;

[0023] Second thick copper gaskets are fixedly arranged at the center positions of both ends of the upper layer of the semi-conductive silicone rubber corresponding to the positions of the first thick copper gaskets;

[0024] The first thick copper gasket and the second thick copper gasket are integrally formed by two sets of the semi-conductive silicone rubber to ensure reliable connection between the connector outer shield, the first thick copper gasket, the second thick copper gasket, and the thick copper mesh;

[0028] The thickness of the second thick copper gasket is 2 mm;

[0029] The position of the thick copper mesh corresponding to the second thick copper gasket is compressed to 1 mm by the second thick copper gasket;

[0030] The metal fittings used in the prefabricated composite grounding clamp are all washed with alcohol and then dried at low temperature, and then immersed in an adhesive for 2 seconds and then taken out to dry at low temperature;

[0031] The prefabricated composite grounding clamp is provided with a clamping groove, which is convenient for fixing in the mold;

[0032] The prefabricated composite grounding clamp and the connector body are placed in a related mold for integral injection molding, and the connector body is fixedly connected to the prefabricated composite grounding clamp;

[0038] 2. The product installation environment is complex, there is a gap between the metal parts and the rubber parts, impurities or water vapor enter, causing the clamp to be contaminated or rusted, resulting in unstable contact;

[0039] 3. During the installation process, the product surface is not clean, resulting in a large surface resistance of the product itself, and thus unstable contact with the grounding clamp or grounding ear;

[0040] 4. If the product is operated for a long time in an environment with large temperature and humidity changes or large temperature difference between day and night, the rubber product will shrink and expand to varying degrees, while the size of the metal parts is fixed, and there is a risk of grounding failure;

[0041] 5. Rubber products will age to varying degrees on their surface in harsh environments, causing the surface resistance of the rubber shielding layer to increase, leading to the risk of poor connection with the grounding clamp or grounding ear.

[0042] The beneficial effects of the utility model are:

[0043] 1. Replace the original two methods of grounding with grounding clamp and grounding ear. The embedded prefabricated grounding clamp grounding method can completely avoid the problem of unstable contact between the outer shield and the grounding wire;

[0044] 2. Enhance the reliability of connectors in power systems to avoid product ablation and breakdown due to grounding problems, which may cause regional power outages or fire accidents;

[0045] 3. The grounding clamp is integrally formed on the product, and combined with the grounding ear and metal clamp for composite grounding to ensure grounding reliability;

[0046] 4. Utilize the two-dimensional plane stretchability of the copper braided mesh and fit it in the area with slight deformation during the connector installation process to ensure the integrity of the composite clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0118] Embodiment 4:

[0119] Reference Figure 5-9 As shown, a schematic diagram of a stainless steel clamp grounding method and a schematic diagram of a wiring ear grounding method are provided for an embodiment of the utility model. In this embodiment, it includes: a connector body 1, a connector insulating body 2, a grounding wire 4, a grounding point 5, and a fastening bolt 6. The connector body 1 includes a connector outer shield 11 and a connector inner shield 12;

[0120] Specifically, the surface of the conventional connector body 1 is generally a conductive layer, which is grounded by grounding ears or clamps;

[0121] According to statistics, a large part of the connector body 1 ablation accidents occur at the grounding point 5. The reason is that high-voltage induced electricity accumulates on the surface of the connector body 1 for a long time, and discharge occurs at the virtual contact point. After long-term accumulation and unstable discharge, the connector outer shield 11 is ablated or even broken down and burned, causing accidents.

[0122] Causes of accidents caused by grounding:

[0123] 1. For grounding of clamp-type products:

[0124] a. The clamp design defect causes the clamp to fail to make close contact with the surface of the connector outer shield 11;

[0125] b. The clamp is not cleaned properly during installation, resulting in sharp impurities mixed between the clamp and the connector outer shield 11, damaging the surface of the connector outer shield 11;

[0126] c. During the installation of the connector inner shield 12, silicone grease is required. This accessory is an insulating material. During the installation of the clamp, the inner surface is not cleaned properly and the installation grease is mixed in. After long-term operation, the electrical conductivity between the clamp and the outer shield 11 of the connector surface becomes weak;

[0127] d. The surface of the connector body 1 is not clean, resulting in a high resistance on the surface of the connector outer shield 11, and thus the electrical conductivity between the clamp and the surface of the connector outer shield 11 becomes weak;

[0128] e. Environmental factors: If the actual operating environment of the connector body 1 is an environment with large differences in high and low temperature values, when the connector body 1 and the clamp are made of different materials, there will be inconsistent shrinkage, resulting in a gap between the connector body 1 and the clamp, causing a virtual connection;

[0129] f. Environmental factors: In extreme operating conditions, such as offshore wind power, the air humidity is high and a certain amount of salt is attached. Long-term operation causes the clamp to rust, reducing the conductivity between the clamp and the connector body 1.

[0130] 2. Grounding for ear-type products:

[0131] a. The grounding point is small and single-point contact is unreliable;

[0132] b. Aging of the rubber material causes the surface resistance of the rubber material to decrease;

[0133] c. If problems such as uneven rubber material occur occasionally, it cannot achieve the purpose of reliable grounding.

[0134] The utility model implants the retractable copper mesh into the outer shield of the product and forms the connector together. The externally led grounding lug is composed of two layers of copper and semi-conductive silicone rubber. The built-in retractable metal clamp is integrally formed with the outer shield to form a good interconnected conductor.

[0135] The external grounding lug and the grounding wire are pressed tightly by a large gasket, and the silicone grounding lug, copper sheet grounding lug, copper mesh and grounding wire are reliably connected;

[0136] When the product is in high-voltage operation, the induced voltage on the outer shield surface of the connector is connected to the ground wire through the copper mesh and semi-conductive silicone rubber at the same time, and then to the earth, ensuring that the connector surface has zero potential and effectively protecting the power system.

[0137] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or position relationship shown.

[0138] It is only for the convenience of describing the present invention and simplifying the description, and it does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore it should not be understood as limiting the present invention.

[0139] In the present invention, unless otherwise clearly specified and limited, a first feature being “on” or “under” a second feature may mean that the first and second features are in direct contact with each other, or the first and second features are in indirect contact with each other through an intermediate medium.

[0140] Moreover, “above”, “above” and “on top” of a first feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature.

[0141] A first feature being “below,” “beneath,” or “below” a second feature may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a smaller horizontal height than the second feature.

[0142] The above are only specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
