J-1型10kV开关柜避雷器试验专用杆
摘要：
本实用新型公开了一种J-1型10kV开关柜避雷器试验专用杆，包括中空绝缘杆、试验芯线和试验屏蔽线，所述中空绝缘杆顶端设置有金属钩，上部设置有第一屏蔽环，中部设置第一圆孔，所述试验芯线一端和金属钩底部连接，另一端通过第一圆孔从中空绝缘杆里引出来；所述第一圆孔下端设置有第二屏蔽圆环和第二圆孔，所述试验屏蔽线一端和第一屏蔽环连接，另一端通过第二屏蔽圆环从第二圆孔处引出来。本实用新型在使用过程中，首先将试验芯线的仪器端接头连接仪器，再将试验屏蔽线的另一端接到高压微安表的外壳上，最后将金属钩与避雷器连接，打开仪器电源进行绝缘试验。本实用新型测量准确度较高，避免了对设备的错误判断，消灭了安全隐患。
摘要（英）：

The utility model discloses a J-1 type special rod for 10kV switch cabinet arrester test, comprising a hollow insulating rod, a testing core wire and a testing shielding wire. The hollow insulating rod is equipped with a metal hook in the top, a first shielding ring in the upper, and a first circular hole in the middle; one end of the testing core wire is connected with the bottom of the metal hook, and the other end of the testing core wire is led out from the hollow insulating rod via the first circular hole; a second shielding circular ring and a second circular hole are arranged below the first circular hole; and one end of the testing shielding wire is connected with the first shielding ring, and the other end of the testing shielding wire is led out from the second shielding circular ring via the second circular hole. During use of the J-1 type special rod, a contact in an instrument end of the testing core wire is connected with an instrument, the other end of the testing shielding wire is connected with a housing of a high-voltage microammeter, the metal hook is connected with the lightning arrester, and the instrument is powered on to carry out insulation test. The J-1 type special rod for 10kV switch cabinet arrester test is highly accurate, avoids misjudgment of equipment, and eliminates hidden safety troubles.
