Abstract
The present invention discloses a composite hollow line suspension insulator which relates to a line suspension insulator for high-voltage transmission lines and electrified railway lines. An insulating tube is hollow, and an umbrella skirt is arranged at the outside of the hollow insulating tube. Hardware joints are inserted into both ends of the insulating tube. The outsides of both ends of the insulating tube are respectively connected with hardware. The hardware joints are inserted into both ends of the insulating tube, and are connected reliably, so the length of the hardware is longer. Thus, electric field distribution is improved, and mechanical strength is strengthened; insulating material is filled in the insulating tube, which raises insulating properties; a conductor for improving the electric field distribution is arranged, which raises flashover voltage; electronic elements, such as sensors, etc., are buried, which enables the composite hollow line suspension insulator to intelligentize and carry out online monitoring. The present invention has the advantages of even electric field distribution, high flashover voltage, reliable hardware connection and strong insulating properties, and can be popularized as post insulators and all composite insulators comprising sleeves.
Description
Technical field
The present invention relates to the circuit suspension insulator that a kind of ultra-high-tension power transmission line and electric railway circuit are used.
Background technology
In electric power system, generator, transformer, insulator are main three-major-items.The effect of insulator is that current potential conductor inequality is separated, and not allowing has electric current to pass through between the conductor, to keep their different current potentials.Insulator is generally made by the high insulating material of resistance, and it can isolate conductor charged or different potentials, and electric current can be circulated by certain direction.According to the difference of insulating material, insulator can be divided into porcelain insulator, glass insulator and composite insulator three major types.According to the difference of purposes, insulator can be divided into line insulator, post insulator and sleeve pipe three major types.
Composite insulator generally is made up of plug, full skirt and metal termination three parts, plug is the bearing part of insulator mechanical load, being again the major part of interior insulation simultaneously, is the fibre-reinforced resin leading-drawing rod of a kind of one-way glass, is a kind of in the glass fiber reinforced plastics product.Full skirt is the external insulation part of insulator, its role is to the leakage distance that provides necessary and protects plug to exempt from the invasion and attack of atmospheric environment, and full skirt is generally made with macromolecular material.The metal termination is the coupling part of insulator and high voltage transmission line, shaft tower, also is the clamping portion of plug simultaneously, makes with metal material.Owing to composite insulator has advantages such as in light weight, that intensity is high, resistant sudden strain of a muscle ability is strong, manufacturing process is simple, therefore worldwide obtained using widely.
Since composite insulator came out, the circuit suspended compound insulator that is used on the circuit all used structure recited above bar none.The composite insulator that is used for post insulator and sleeve pipe, because various needs, some composite hollow insulators have also been used, as " a kind of hollow type internal electrical hot oil bath heat anti-" pollution flashover " high-tension insulator " (patent No. 01219153), it is made up of hollow type insulator, electric heater, temperature sensor, Automatic Temperature Control; The hollow type insulator encapsulates with base and upper cover base respectively.It has solved " pollution flashover " phenomenon that the high voltage supply system insulator produces when foggy weather, to ensure the operate as normal of electric power system.
Summary of the invention
The objective of the invention is at above-mentioned present situation, it is even to aim to provide a kind of Electric Field Distribution, and that flashover voltage height, metal-ware connect is reliable, mechanical strength is high, on-line monitoring composite hollow line suspension insulator easily.
The implementation of the object of the invention is, composite hollow line suspension insulator, and insulated tube 1 is a hollow, full skirt 2 is arranged outside the hollow insulated tube 1, metal-ware 3 joint areas insert inboard, insulated tube two ends, and metal-ware 4 is surrounded the outside, insulated tube two ends, and metal-ware 3 is connected with metal-ware 4 respectively.
The present invention has the following advantages:
1, metal-ware 3 joint areas insert in the insulated tube 1, and be connected with mechanical type or the adhered inboard two ends of itself and insulated tube that make, insertion portion can be longer than the length of the metal-ware of compound solid line insulator, the Electric Field Distribution of promptly having improved insulator has strengthened the mechanical strength of insulator again greatly, and then with mechanical type or adhered metal-ware 4 is connected the two ends in insulated tube 1 outside, this frame mode makes the connection of metal-ware more reliable;
2, because of insulated tube is hollow, can in insulated tube, arrange the conductor that improves Electric Field Distribution, improved the flashover voltage of insulator;
3, can fill insulating material 5 in insulated tube inside, improve the insulating properties of insulator;
4, because of insulated tube is hollow, electronic components such as transducer can be set in insulated tube, it is intelligent that insulator can be realized, can carry out on-line monitoring
Electric Field Distribution of the present invention is even, and that flashover voltage height, metal-ware connect is reliable, insulating properties is strong, can promote to be used for post insulator and sleeve pipe at all interior composite insulators.
Description of drawings
Accompanying drawing is a partial structurtes schematic diagram of the present invention
Embodiment
With reference to accompanying drawing, the present invention is by hollow insulated tube 1 and outer full skirt 2 thereof, and the metal- ware 3,4 that is connected in two ends constitutes.Metal-ware 3 joint areas insert the insulated tube two ends, are connected with metal-ware 4 respectively outside the insulated tube two ends.The insulated tube two ends inside and outside respectively with joint area, metal-ware 4 usefulness mechanical types or adhered linking to each other of metal-ware 3.
Insulated tube 1 hollow space can fill insulating material 5.
Full skirt of the present invention is the external insulation part of composite hollow line suspension insulator, and it provides necessary creepage distance and protects insulated tube to avoid environmental impact.Pipe is the built-in electrical insulation parts of composite hollow line suspension insulator, and it is used for guaranteeing mechanical load.Metal-ware is attached to pipe and goes up to transmit mechanical load.
