Description

Technical Field

[0001] The utility model belongs to the technical field of electric power, and in particular relates to a vertical multi-angle insulating shield base of an electrical device and a protective piece thereof. Background Art

[0002] In the power industry, distribution network construction has always been a key link. It connects power generation, transmission and end users, and is an important link in achieving efficient operation of the power system.

[0003] The investment in distribution network is mainly concentrated on the insulation transformation of lines and the upgrading of distribution equipment. In order to ensure the actual effect of distribution network construction, insulation is required at important potential risk locations such as equipment connections. The joints of outdoor equipment such as pole-mounted circuit breakers and pole-mounted transformers in the distribution network are exposed and need to be protected. Currently, silicone rubber sheaths or insulating coating materials are used for wrapping.

[0004] However, the current approach has many shortcomings:

[0005] 1. The silicone rubber sheath currently used cannot be completely sealed. Not only is it not waterproof, but water may even accumulate inside the sheath, causing metal corrosion and loose fasteners, which directly leads to poor contact and secondary failures.

[0006] 2. The silicone rubber sheath is made of soft material and is fastened by buckles. Due to aging, wind and sun, the buckles are easy to loosen and even fall off completely under external forces, losing their protective function. Problems are not easy to be discovered, which seriously affects the safe and stable operation of the power grid. To ensure safe operation, it needs to be replaced every three years on average, which brings a lot of work and high maintenance costs.

[0007] 3. With the upgrading of equipment and new requirements for construction technology, there are many types of hardware and equipment terminals. The silicone rubber sheaths currently used often do not match the equipment model, hardware and equipment terminal angles, resulting in partial metal exposure, which does not play an insulating protection role and is easily corroded by wet flashover, dirty flashover, salt spray and chemical gas. Outdoor power distribution equipment is affected by its structure and environment, and birds are prone to nesting on it. Especially in rainy and snowy weather, it is easy to cause equipment discharge and phase short circuit, which may cause personal electric shock risks and grid tripping;

[0008] 4. The silicone rubber sheath and the metal cannot fit tightly together to form an air insulation layer. The thermal conductivity of air is about 0.0244W / m·K, and the thermal conductivity is poor. The temperature of the metal connection cannot be measured well on the outside.

[0009] 5. When using insulating coating materials for insulation, the quality of the coating is completely dependent on the construction personnel, the coating thickness cannot be determined and measured, and the coating material cannot be tightly bonded to the metal to prevent rainwater from entering. At the same time, the price of the coating material is high, which increases the cost without achieving a good effect. Utility Model Content

[0024] Beneficial effects:

[0025] 1. Cover the equipment wiring in place. Traditional protective measures only wrap a layer of silicone rubber sheath at the equipment wiring. The shape of the sheath itself is not fixed, and it cannot guarantee that the internal conductor is completely covered during installation, which may cause the conductor to be exposed. The upper and lower covering plates of the utility model are made of hard insulating materials. The design process refers to the shape of the equipment wiring. After installation, the conductor at the equipment wiring can be completely covered, and there is no problem of inadequate covering.

[0026] 2. Sufficient insulation distance can be ensured. Due to its material problem, the traditional silicone rubber sheath is soft and there may be insufficient gap between the sheath and the internal conductor. The utility model adopts hard material and its shape is designed according to the shape of the wiring point to ensure that there is enough safety distance between the internal and the conductor.

[0027] 3. Easy installation. Traditional silicone rubber sheaths are soft in material and have an irregular shape. They need to be installed with both hands. The buckles are installed one by one, which takes a long time to install and is difficult to install. The utility model has a simple installation process and comes with a locking device. The installation process can be completed with one hand and can be installed in place in one go.

[0028] 4. Cost reduction. The utility model provides a container for injecting insulating materials to ensure that the conductors at the equipment connection points are properly covered. After the insulating materials are completely solidified, the protective performance can be guaranteed for 10 years. Compared with the traditional protective measures that are replaced every 2-3 years, the cost is greatly reduced.

[0029] 5. The utility model has a multi-angle adaptive compatible structure, which can adapt to various wiring forms and equipment types. Compared with the traditional sheath that can only be applied to one angle, it has a wider range of applications, is more convenient for on-site construction personnel to operate, and has lower construction difficulty.

[0030] 6. Adaptable to a variety of hardware. Traditional silicone rubber sheaths are only suitable for one type of hardware, but the utility model can be applied to a variety of hardware, which is more applicable and easier for construction workers to operate.

[0031] 7. Convenient and efficient selection. The hardware and wiring forms of existing power distribution equipment are generally covered by traditional sheaths, and it is impossible to distinguish the type of hardware and other information from the appearance. The utility model has a multi-angle adaptive compatible structure and can adapt to a variety of hardware features. There is no need to confirm the relevant information of the equipment, and it can be directly selected, which provides convenience for selection.

[0032] 8. Inventory preparation is simple and efficient. The utility model can replace various types of silicone rubber sheaths suitable for electrical equipment, and can solve the problem caused by too many types of sheaths and the inability of different types of sheaths to be universal.
