摘　　要：中性点避雷器装设位置较高,操作平台狭小,给中性点避雷器预试工作带来一定的安全风险、设备安全隐患等,严重影响预试工作效率。基于此,本人设计一款中性点避雷器试验专用间隙屏蔽罩,包括屏蔽底座、屏蔽罩壁和金属连接件,用于屏蔽中性点避雷器放电间隙,保证放电间隙在试验电压下不击穿,使试验顺利完成。该屏蔽罩可避免重复多次攀爬中性点避雷器拆装放电间隙接地极。The high installation position of the neutral point arrester and the narrow operation platform bring certain safety risks and equipment safety hazards to the pre-test work of the neutral point arrester,which seriously affects the efficiency of the pre-test work.Based on this,a special gap shield for the neutral point arrester test is designed,including the shield base,shield wall and metal connectors,to shield the discharge gap of the neutral point arrester,to ensure that the discharge gap does not break down under the test voltage,so that the test can be successfully completed.The shield can avoid repeatedly climbing the neutral point arrester to disassemble the discharge gap grounding electrode.
