Description

套管吊装专用工具Special tools for casing hoisting

技术领域 technical field

本实用新型涉及一种电力系统套管吊装专用工具,属于起重机吊具技术领域。 The utility model relates to a special tool for hoisting a power system bushing, which belongs to the technical field of crane spreaders.

背景技术 Background technique

电力系统的变压器安装及维护时,经常会遇到变压器套管的拆装问题,一般套管的拆装是通过吊装设备的配合完成的。在油纸电容式套管由水平放置状态起吊至竖立状态过程中,位于套管底部的均压球受力很大,为了防止均压球损伤和控制套管正常吊起,需要用粗绳环绕均压球上部,人为施力使均压球脱离包装箱箱底,由于人为施力与吊车施力的配合难以默契,使得套管起吊时均压球由于受力不均而被损坏的现象时有发生,在CT的吊装过程中也存在相同的问题;另外上述吊装方法还存在着作业时间长、需要操作人员数量多等缺陷。 During the installation and maintenance of transformers in power systems, disassembly and assembly of transformer bushings are often encountered. Generally, the disassembly and assembly of bushings is completed through the cooperation of hoisting equipment. When the oil-paper capacitive bushing is hoisted from a horizontal state to an upright state, the pressure equalizing ball at the bottom of the bushing is subjected to a large force. On the upper part of the pressure ball, artificial force is applied to make the pressure equalizing ball break away from the bottom of the packing box. Since the cooperation between the artificial force and the force of the crane is difficult to tacitly cooperate, the phenomenon that the pressure equalizing ball is damaged due to uneven force when the casing is hoisted occurs from time to time. , the same problem also exists in the hoisting process of CT; in addition, the above-mentioned hoisting method also has defects such as long operation time and a large number of operators.
