Description

Technical Field

[0001] The utility model relates to a multi-angle adaptive equipment wire clamp insulation shield for a transformer and a transformer protection piece thereof, belonging to the field of electric power. Background Art

[0002] In the power industry, the construction of distribution networks 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. With the acceleration of global energy transformation, especially the rapid development of renewable energy and energy storage, the construction of distribution networks has become the focus of the power grid.

[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, the state and the industry have relevant clear standards for the insulation of important hidden dangers such as equipment connections. Among them, Article 11.2.1 of GB 51302-2018 "Design Standard for Overhead Insulated Distribution Lines" stipulates that "the connection between equipment, hardware and insulated wires should be insulated, and measures such as insulation shields or insulation wrapping can be adopted. The insulation shield should be made of heat shrinkable or prefabricated insulation materials, and the wrapping material should be self-adhesive"; Article 11.2.2 stipulates that "the insulation shield and wrapping materials should prevent dirt accumulation and water ingress, and should meet flame retardant requirements." "DL / T602-1996 Overhead Insulated Distribution Line Construction and Acceptance Procedures" clearly requires that "the exposed part of the joint must be insulated and a special insulation shield must be installed."

[0004] The connectors 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, they are wrapped with silicone rubber sheaths or insulating coating materials.

[0005] However, the current approach has many shortcomings:

[0006] 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.

[0007] 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.

[0008] 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;

[0009] 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.

[0010] 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.

[0011] Distribution network equipment is the focus of power grid investment. The large amount of investment and the large number of equipment make the corresponding safety hazards more prominent. Among them, pole-mounted circuit breakers, link switches, transformers and other equipment and wire connections are often caused by power accidents due to weather reasons, small animals, bird nesting, external force damage, etc., and the insulation problem of the last 10cm is becoming increasingly prominent. With the advancement of primary and secondary integration, one terminal needs to connect multiple wires such as PT, and the problem is more prominent. The insulation of outdoor distribution network equipment urgently needs innovation to solve the problem of insulation of the last 10cm. Therefore, it is of great significance to study the integrated insulation solution of equipment terminals, hardware, and cables. Utility Model Content
