Research on APG Process of 10 kV Wall Bushing

为确保10 kV穿墙套管的电气性能和力学性能,对10 kV穿墙套管的成型自动压力凝胶(APG)工艺进行研究,重点通过原材料配方、混料工艺、浇注成型工艺、固化成型等条件的研究,确定了材料配方、混料真空度、混料搅拌时间、成型温度、浇注压力、保压压力、保压时间等关键制造参数,形成了一套可行的制造工艺,并对采用该工艺制造的穿墙套管的力学性能和电气性能进行测试。结果表明:采用APG工艺制造的穿墙套管力学性能和电气性能可靠,适用于实际生产制造。

In order to ensure the electrical and mechanical properties of 10 kV wall bushing, the automatic pressure gel forming(APG) process of 10 kV wall bushing was studied. The raw material formulation,mixture process, pouring molding process, and curing molding were mainly studied to determine the material formula, mixture vacuum, mixing time, molding temperature, pouring pressure, holding pressure, and pressure-holding time, and a feasible manufacturing process was formed. Then a wall bushing was fabricated by this process, and its mechanical and electrical properties were tested. The results show that the mechanical and electrical properties of the wall bushing are reliable, which is suitable for the actual production.
