用于复合绝缘子表面电阻率的测试装置
摘要：
本发明公开了一种用于复合绝缘子表面电阻率的测试装置，所述测试装置包括：第一电极；第二电极，第二电极与第一电极上下相对设置；测试夹，测试夹与第一电极相连，测试夹与第二电极相连，包括：第一销轴；上臂，上臂与第一电极相连；下臂，下臂与第二电极相连，上臂与下臂通过第一销轴相连，且上臂与下臂围绕第一销轴可发生旋转，通过控制上臂和下臂之间的开合以驱动第一电极与第二电极的张开与闭合。根据本发明实施例的用于复合绝缘子表面电阻率的测试装置，通过控制上臂和下臂的开合状态，即可驱动第一电极与第二电极的张开与闭合，测试操作方便，测量结果准确。
摘要（英）：

The invention discloses a device for testing the surface resistivity of a composite insulator, and the device comprises a first electrode; a second electrode which is opposite to the first electrode in a vertical direction; a test clamp which is connected with the first electrode and the second electrode, and comprises a first pin shaft; an upper arm which is connected with the first electrode; and the lower arm which is connected with the second electrode, wherein the upper arm and the lower arm are connected through the first pin shaft, and the upper and lower arms can rotate around the first pin shaft. The opening and closing of the upper and lower arms are controlled so as to drive the first and second electrodes to open and close. According to the embodiment of the invention, the device can drive the opening and closing of the first and second electrodes through controlling the opening and closing of the upper and lower arms, is convenient in test operation, and is accurate in measurement result.
