本实用新型涉及用于“V”型绝缘子起吊的装置,更具体涉及一种用于“V”型绝缘子串振动试验的“V”型绝缘子串悬吊装置。The utility model relates to a device for hoisting a "V" type insulator, in particular to a "V" type insulator string suspension device used for a vibration test of a "V" type insulator string.
背景技术:Background technique:
在高压输变电领域,绝缘子串是用于连接架空输电线路与铁塔,并在二者之间起绝缘作用。随着输电线路电压等级的逐步提高,绝缘子串的串长也在逐步加长,串型则分为常规直线串,耐张串,以及防止架空线路风偏的V型串。在线路设计初期,需要在实验室对不同串型的绝缘子做工频或直流湿耐受试验、雷电冲击干耐受试验、操作冲击湿耐受试验、电晕和无线电干扰试验、振动蠕变等相关电气和机械性能试验。这就需要在实验室里布置不同串型的绝缘子串。In the field of high-voltage power transmission and transformation, insulator strings are used to connect overhead transmission lines and iron towers and provide insulation between them. With the gradual increase of the voltage level of the transmission line, the string length of the insulator string is also gradually lengthened, and the string types are divided into conventional straight strings, strain strings, and V-shaped strings to prevent wind deflection of overhead lines. In the early stage of line design, it is necessary to do power frequency or DC wet withstand test, lightning shock dry withstand test, operation shock wet withstand test, corona and radio interference test, vibration creep, etc. in the laboratory for different string insulators. Relevant electrical and mechanical performance tests. This requires the arrangement of insulator strings of different string types in the laboratory.
实验室“V”型绝缘子的悬吊和组装较为复杂,常规的悬吊方法是使用一个或两个垂直悬吊的电动葫芦悬挂一个钢制横担,将“V”型绝缘子串的两个端部挂在横担上,两个悬挂点的位置需要根据绝缘子的串长和两串绝缘子的夹角来计算。缺点是自动化程度低、承受交变载荷能力差、刚度小,使用寿命短;The suspension and assembly of the "V" insulator in the laboratory is relatively complicated. The conventional suspension method is to use one or two vertically suspended electric hoists to hang a steel cross arm, and connect the two ends of the "V" insulator string. The upper part is hung on the cross arm, and the positions of the two suspension points need to be calculated according to the string length of insulators and the angle between the two strings of insulators. The disadvantages are low degree of automation, poor ability to withstand alternating loads, low rigidity, and short service life;
