Description
Technical Field
[0001] The utility model relates to the technical field of power grids, in particular to a power grid power supply parallel type high-strength insulation device. Background Art
[0002] The whole of the power system consisting of substations and transmission and distribution lines of various voltages is called the power grid. It includes three units: substation, transmission, and distribution. The task of the power grid is to transmit and distribute electrical energy and change the voltage. Insulation devices are required in the power grid, and the insulation devices are insulators.
[0003] Insulators are used to support conductors and prevent current from returning to the ground. Insulators are used to support conductors and prevent current from returning to the ground in overhead transmission lines. Support conductors. Insulators have high mechanical strength and durability, can withstand certain mechanical loads, and provide support for power equipment. Prevent current from returning to the ground. By effectively isolating direct contact between wires and between wires and brackets, current is prevented from passing through undesired paths, ensuring the safety and reliability of power transmission and substation. In addition, insulators also have anti-pollution functions, which can resist the influence of the atmospheric environment on insulation performance and extend their service life. In general, insulators are important components to ensure the safe operation of power systems.
[0004] Since the insulation devices are used at high altitudes, they are often affected by strong winds and other strong air currents. Over time, they are prone to deflection, which in turn affects the reliability of the wire connection. However, the existing wind-proof deflection insulation devices on the market do not have an ideal deflection prevention effect. When deflection occurs, they cannot be reset in time to return to their original positions. When deflection occurs, the entire wind-proof deflection insulation device will be subjected to a large torque. After a long time, the insulator is prone to breakage, which poses a certain safety hazard. Therefore, in order to ensure the better use of the insulator, a tension spring is usually set on the outside of the insulator to provide a buffer when the insulator shakes.
[0005] Then, the tension spring is unstable. For example, after long-term use, the elastic force of the tension spring will weaken, resulting in lower buffering for the insulator. In addition, there is a lack of shielding on the outside of the tension spring, which makes the tension spring prone to breakage after being eroded by rainwater. In view of this, a grid-powered parallel high-strength insulation device is proposed to solve the above problems. Utility Model Content
