Abstract

In order to solve a flashover breakdown phenomenon of a high-voltage coil in X-ray equipment, the invention discloses a closed type high-voltage coil and a manufacturing method thereof. The closed type high-voltage coil comprises a coil framework, coil leads, insulating layers among the leads, and a sealing layer, wherein the coil leads and the insulating layers among the leads are integrally sealed by the sealing layer; materials of the sealing layer are quartz and epoxy resin; and the ratio by weight of the materials of the sealing layer, namely the ratio of the quartz to the epoxy resin is 1.5-2.5:1. The manufacturing method comprises the steps of high-voltage coil pack processing, epoxy resin preparation, pouring and the like. The closed type high-voltage coil has the beneficial effects that since the quartz is added to the epoxy resin, a withstand voltage increasing function is fulfilled in the epoxy resin by utilizing a high insulating property of the quartz, so that the high-voltage coil obtained after being poured by the quartz and the epoxy resin has the advantages that the flashover phenomenon is eliminated and the withstand voltage is increased by 1.5 times than before; and the maintenance is convenient, a high-voltage pack can be directly replaced by a user and does not need to be processed at all.
