Abstract

The invention discloses a condensation preventing device for solid insulated switchgear. The switchgear comprises a cable chamber and a horizontal busbar chamber, wherein each of the cable chamber and the horizontal busbar chamber is provided with a vertical sealing plate and a door; the surface of each of the sealing plates is provided with a plastic spraying layer, and the surface of each of the doors is provided with a plastic spraying layer; the plastic spraying layer on the inner side of the inner side surface of each of the sealing plates and the doors is coated with a resin type MYQS-1 hydrophilic material coating. The invention also discloses a manufacturing method of the condensation preventing device. Due to the adoption of the technical scheme, the condensation resistance level of the self surface of the solid insulated switchgear is improved; on the one hand, condensate is initiatively generated on the inner side of a shell consisting of the functional chambers and forms water drops which then flow into a guide channel and is discharged out of the switchgear, and thus the air humidity in the switchgear is reduced, and a live part cannot reach the saturation humidity under which the condensate generates; on the other hand, a micron-nanoscale coarse structure and a hydrophobic material surface with low surface energy are established on the surface of the solid insulated switchgear, so that the concentrate is not easy to generate on the surface of the solid insulated switchgear; therefore, the purpose of ensuring the safety operation of electrical equipment is achieved.

Description

Technical field [0001] The invention belongs to the technical field of solid insulated switchgear. More specifically, the present invention relates to a condensation prevention device for solid insulated switchgear. In addition, the present invention also relates to a method of manufacturing the condensation prevention device. Background technique [0002] In the field of high-voltage switchgear, solid insulation is the future development direction. The internal space of high-voltage switchgear (7.2kV~40.5kV) is very compact. In order to ensure the internal insulation level and the reliable operation of the device, higher requirements are put forward for moisture and condensation prevention in the equipment. [0003] Switchgear and control equipment condensation test method (DL / T593 appendix H) stipulates: Turn on the spray device to make the relative humidity in the climate room reach 95%-100% as soon as possible. When the surface of the external insulation of the test product...
