Abstract
The utility model relates to an insulating pull rod with a vacuum-impregnation epoxy glass-cloth tube. The pull rod is used for manipulating high-voltage electrical equipment in the power industry, and comprises a joint I, an impregnated epoxy glass-cloth tube, and a joint II, wherein, the joint I and the joint II are arranged at the two ends of the impregnate epoxy glass-cloth tube respectively; and an internal cavity formed by the joint I, the joint II and the impregnated epoxy glass-cloth tube is classified as a vacuum cavity. The utility model has the following advantages: the joint I, the joint II and the impregnated epoxy glass-cloth tube are combined, so that the internal cavity inside the impregnated epoxy glass-cloth tube forms the vacuum cavity which can improve the insulating property of the insulating pull rod; the ends of the joint I and the joint II are designed as arc-shaped ends, thereby ensuring uniform distribution of an electric field around the joints during application of a high voltage; and the pull rod has a reliable performance, and is proven by tests to meet the requirements for electrical and mechanical properties, so that the long-lasting problem with the repetition of electrical breakdown can be solved, and the reliability of products is improved.
Description
Technical field
The utility model relates to the insulated tension pole of handling usefulness on the power industry high voltage electric equipment.
Background technology
Relevant by retrieval patent documentation does not retrieve the vacuum impregnation epoxy glass fabric pipe insulation pull bar identical with the utility model structure at present as yet.The insulated tension pole that is used to handle, close a floodgate, separate on the existing high voltage electric equipment generally adopts insulating rod as intermediate materials two ends to be separated, and reaches the purpose of insulation; Solid insulating rod is because its weight is brought very big inconvenience to mechanism's operation greatly; Hollow insulated tube makes insulation effect not ideal enough because its pipe internal memory has air, and electric breakdown accident usually takes place, and exists very big potential safety hazard, thus be necessary existing insulated tension pole is improved, to improve the performance of product.
Summary of the invention
The purpose of this utility model is that a kind of have dependable performance, vacuum impregnation epoxy glass fabric pipe insulation pull bar easy to use will be provided.
Technical characterictic of the present utility model is: be designed to the vacuum impregnation epoxy glass fabric pipe insulation pull bar be made up of joint I, dipping expoxy glass stringing, joint II on the basis of considering compact conformation, dependable performance, at the two ends of dipping expoxy glass stringing difference joint I, joint II, described joint I, joint II are vacuum chamber with the internal cavities that dipping epoxy glass fabric pipe forms.
Described joint I is made up of connecting rod I, link I, termination I, and connecting rod I links to each other with outside driving member, link I and the mutually airtight connection of dipping expoxy glass stringing, and described termination I is the circular arc termination.
Described joint II is made up of connecting rod II, link II, termination II, and connecting rod II links to each other with outside driving member, link II and the mutually airtight connection of dipping expoxy glass stringing, and described termination II is the circular arc termination.
The utility model has the advantages that:, make the internal cavities of dipping expoxy glass stringing form vacuum chamber, thereby improved the insulation property of insulated tension pole owing to take joint I, joint II to combine with dipping expoxy glass stringing; Because the termination of joint I, joint II is designed to the circular arc termination, thereby has improved joint when applying high voltage, the even distribution of electric field around it; Because insulated tension pole dependable performance of the present utility model, and through verification experimental verification, satisfy electric and the mechanical performance requirement, thereby solved the problem that is prone to electric puncture for a long time, reliability of products improved; Because rational in infrastructure, dependable performance is so there is very big practical and popularizing value.
