技术领域technical field
本发明涉及GIS检测工装设备领域，特别是滑块式双凸轮SF6阀体通用工装。The invention relates to the field of GIS detection tooling equipment, in particular to a general tooling for a slider type double cam SF6 valve body.
背景技术Background technique
随着技术的发展，变电站新建、技改工程中多使用GIS设备代替传统的敞开式设备。GIS（气体绝缘金属封装开关设备）。GIS设备因其占用空间少、运行可靠性高、配制灵活、维护工作量小、检修周期长、不受外界环境条件的影响、适应性强的特点得到普遍应用。GIS的断路器多为SF6（六氟化硫）断路器，SF6断路器的微水测试、充气及检修等逐渐增多。With the development of technology, GIS equipment is often used instead of traditional open equipment in the new construction and technical transformation projects of substations. GIS (Gas Insulated Metal Enclosed Switchgear). GIS equipment is widely used because of its small footprint, high operational reliability, flexible configuration, small maintenance workload, long maintenance cycle, unaffected by external environmental conditions, and strong adaptability. The circuit breakers of GIS are mostly SF6 (sulfur hexafluoride) circuit breakers, and the micro-water test, inflation and maintenance of SF6 circuit breakers are gradually increasing.
现有技术中由于装有SF6设备的内部的SF6气体压力较大，其检测口装有以压紧式法兰连接的逆止阀，需要检测或维修时，需要将逆止阀的阀盖取掉，再人工使用集气阀对准逆止阀进行压紧集气或充气。逆止阀在设备安装形式、尺寸大小各不相同，内部压力又很大，工作人员在进行检测或维修时安装集气阀变得异常困难，需要2-3人协作完成，稍有不慎集气阀就会弹出，对工作人员造成伤害，集气阀接口也会摔坏报废。这种操作方法劳动强度大，工作效率低，严重威胁到人身和设备安全，并且延长了停电检修时间，在一定程度上影响到变电站的安全稳定运行，离标准化作业相差甚远。这就需要一种SF6阀体微水测试、充气及检修工作的专用工装卡具。In the prior art, since the pressure of the SF6 gas inside the SF6 equipment is relatively large, its detection port is equipped with a check valve connected with a compression flange. When testing or maintenance is required, the valve cover of the check valve needs to be removed. , and then manually use the air collecting valve to align the check valve to compress or inflate the air. The installation form and size of the check valve are different in the equipment, and the internal pressure is very large. It becomes extremely difficult for the staff to install the gas collecting valve during inspection or maintenance. It needs 2-3 people to cooperate to complete it. The air valve will pop out, causing injury to the staff, and the air collecting valve interface will also be broken and scrapped. This method of operation is labor-intensive and low-efficiency, which seriously threatens the safety of people and equipment, and prolongs the maintenance time of power outages, which affects the safe and stable operation of the substation to a certain extent, which is far from standardized operations. This requires a special tooling fixture for SF6 valve body micro-water testing, inflation and maintenance work.
