本实用新型涉及电气设备维修技术领域，具体地说是涉及一种用于更换直线单串绝缘子串的直线扁担卡。 The utility model relates to the technical field of electrical equipment maintenance, in particular to a straight pole card used for replacing a straight single-string insulator string.
背景技术 Background technique
我国是世界上最早开展带电作业的国家之一，500kV及以下线路带电作业常规项目开展与之相应的工器研制有相当成熟的经验；但750kV等级线路是新一级电压等级，由于线路结构的特殊性，客观上决定了只能借鉴不能照搬或直接应用500kV及以下线路带电作业常规项目，开展与之相应的工器研制的技术、数据和经验，而必须结合750kV线路具体情况，开展系列的、科学的、有针对性的带电作业项目研究和工器具的开发，服务于750kV带电作业的开展需要。 my country is one of the first countries in the world to carry out live work. It has quite mature experience in the development of corresponding tools for conventional live work projects of 500kV and below lines; however, 750kV lines are a new level of voltage. The particularity objectively determines that we can only learn from the technology, data and experience of the conventional live work projects of 500kV and below lines that cannot be copied or directly applied to carry out the corresponding tool development, but must be combined with the specific conditions of 750kV lines to carry out a series of , Scientific and targeted live work project research and tool development, serving the development needs of 750kV live work.
传统的500KV直线扁担卡结构是用绝缘拉棒将起重丝杠与卡具主体联接，卡具六钩勾住六条导线，起重丝杠座置于线路角钢上。在更换直线单串绝缘子串工作时，操作者收紧丝杠，提起导线，松弛绝缘子串，即可更换。该卡具的缺点是卡具直接提导线，卡具容易伤到导线表面并且容易使导线发生弯曲变形。另外，导线发生弯曲变形后直接影响连接拉棒的调整，所需丝杠行程就比较长，导致加工难度增加，卡具笨重，成本较大。 The traditional 500KV straight pole clamp structure is to use insulating pull rods to connect the lifting screw with the main body of the clamp. The six hooks of the clamp hook six wires, and the lifting screw seat is placed on the line angle steel. When replacing the linear single-string insulator string, the operator tightens the lead screw, lifts the wire, and loosens the insulator string to replace it. The disadvantage of this fixture is that the fixture directly lifts the wire, and the fixture is easy to damage the surface of the wire and easily bend and deform the wire. In addition, the bending deformation of the wire directly affects the adjustment of the connecting rod, and the required screw stroke is relatively long, resulting in increased processing difficulty, heavy fixtures and high cost.
针对330~500kV交流输电线路带电作业工器具的现状，有必要研制适用于开展750kV线路带电作业常规项目的工器具。 In view of the current situation of live working tools for 330~500kV AC transmission lines, it is necessary to develop tools suitable for carrying out routine projects of live working on 750kV lines.
