技术领域technical field
本发明涉及一种电气设备，尤其是涉及一种充气柜传动杆用密封装置。The invention relates to an electrical device, in particular to a sealing device for a transmission rod of an inflatable cabinet.
背景技术Background technique
充气柜内部的三工位开关需要通过传动装置进行开合，传动装置由设置于充气柜外部的三工位驱动装置驱动，传动装置的传动杆从充气柜外部穿入充气柜内部，通过一系列传动步骤完成三工位开关的开合，由于气箱内充满着大于一个标准大气压的SF6气体，SF6气体一方面会污染环境，另一方面，SF6气体泄漏后会降低产品的绝缘性能，引发事故，因此，在传动杆与充气柜的接合处，必须要做好密封，确保SF6气体不发生泄漏，根据使用要求，密封的有效期必须达到30年。The three-position switch inside the inflatable cabinet needs to be opened and closed through the transmission device. The transmission device is driven by the three-position drive device installed outside the inflatable cabinet. The transmission step completes the opening and closing of the three-position switch. Since the gas box is filled with SF6 gas greater than one standard atmospheric pressure, the SF6 gas will pollute the environment on the one hand, and on the other hand, the leakage of SF6 gas will reduce the insulation performance of the product and cause accidents. , Therefore, the joint between the transmission rod and the inflatable tank must be sealed to ensure that the SF6 gas does not leak. According to the use requirements, the validity period of the seal must reach 30 years.
