Though the transformers imported test unit can be by main bus-bar and branch bar butt joint.But for the Phase in One Tank Type GIS product,, carry out three unidirectional butt joints, will waste a large amount of man-hours like this if adopt from branch bar butt joint test.How once butt joint is tested the three-phase of product respectively, becomes the key issue that realizes that this import test unit docks with the Phase in One Tank Type GIS product.
Summary of the invention
The purpose of this utility model provides the three-phase change-over switch that a kind of transformers imported is docked with the Phase in One Tank Type GIS product, and by this switch, once butt joint just can be carried out withstand voltage drawn game to A, B, the C three-phase of product and puts measurement, can increase work efficiency greatly.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
Three-phase change-over switch is used in a kind of GIS product testing butt joint, comprises moving side, quiet side, and described moving side is connected with the Hi-pot test device, and by conductor high pressure is guided to a high-voltage contact part; Described quiet side is connected with the GIS product, it is characterized in that, described quiet side is provided with and is A, B, the C three-phase branch bar that 120 degree angles distribute and three fingertips on same circumference connect tested GIS product respectively, the conversion conductor that it is high-voltage contact that described high-voltage contact partly is provided with a front end, this conversion conductor with respect to fingertip place circular motion, is connected high-voltage contact by gear train respectively with one of three fingertips elasticity; Two other fingertip is by grounding switch ground connection.
In the such scheme, described high-voltage contact part gear train comprises that two 45 degree bevel gears are meshing with each other and realizes 90 degree conversions that wherein the bevel gear of horizontal direction is connected with conversion conductor by an axle; The bevel gear of vertical direction connects the operating mechanism of high-voltage contact portion of external by a drive link.This operating mechanism is a rocking handle.
Described high-voltage contact partly is provided with shielding head and radome, in bevel gear set and fixed part all are included in.
Described static contact comprises the static contact body, is provided with spring contact in the static contact body and exposes, and this spring contact is connected with rotation contact elasticity by the intrinsic spring of static contact.
The utility model makes high-voltage contact partly be designed to rotary way with rotary handle by running part in switch external, be connected with A, B, the C of GIS product respectively, once butt joint just can be carried out withstand voltage drawn game respectively to A, B, the C three-phase of product and puts measurement, has improved work efficiency greatly.
