Description
Technical field
The utility model relates to a kind of isolation earthing device for solid insulation ring main unit.
Background technology
At present, solid insulation ring main unit isolation earthing device adopts split-type structural, adopts 2 moving contacts to clamp 1 fixed contact, 2 up and down connection isolation of the moving contact other end or grounding contact.Because 2 long-term up and down wearing and tearing of moving contact cause clamping power inhomogeneous, very easily produce virtual connection electric discharge and cause that solid insulation ring main unit is creepage to be burnt.
Summary of the invention
For effectively even clamping, try hard to avoid and exempt from the generation of virtual connection situation, the utility model provides isolation earthing device for a kind of solid insulation ring main unit.
A kind of solid insulation ring main unit with isolation earthing device for the first time moving contact (2) be placed on initiatively contact (1) left upper end, one side is fixed on initiatively contact (1) from lower from upper the first screw rod (4), the first spring (8), the 5th spring (12), the first nut (16) used successively, and opposite side is fixed on initiatively contact (1) from lower from upper the second screw rod (5), the second spring (9), the 6th spring (13), the second nut (17) used successively; Moving contact (3) is placed on initiatively contact (1) upper right side for the second time, one side uses the 3rd screw rod (6), the 3rd spring (10), the 7th spring (14), the 3rd nut (18) to be fixed on initiatively contact (1) from lower on white successively, and opposite side uses the 4th screw rod (7), the 4th spring (11), the 8th spring (15), the 4th nut (19) to be fixed on initiatively contact (1) from lower on white successively.
Initiatively all there is a protruding gear in contact (1) upper left corner, the lower left corner, the upper right corner, the lower right corner.
Moving contact (2) upside, downside all have a protruding gear for the first time.
Moving contact (3) upside, downside all have a protruding gear for the second time.

Embodiment
In accompanying drawing 1, isolation grounding contact body (20) be placed in initiatively contact (1) and for the first time moving contact (2), for the second time between moving contact (3), because all there is a protruding gear in active contact (1) upper left corner, the lower left corner, the upper right corner, the lower right corner, moving contact (2) upside, downside all have a protruding gear for the first time, and moving contact (3) upside, downside all have a protruding gear to guarantee isolation grounding contact body (20) running orbit reliability for the second time.A kind of solid insulation ring main unit with isolation earthing device for the first time moving contact (2) be placed on initiatively contact (1) left upper end, one side is fixed on initiatively contact (1) from lower from upper the first screw rod (4), the first spring (8), the 5th spring (12), the first nut (16) used successively, and opposite side uses the second screw rod (5), the second spring (9), the 6th spring (13), the second nut (17) to be fixed on initiatively contact (1) from lower on white successively; Moving contact (3) is placed on initiatively contact (1) upper right side for the second time, one side is fixed on initiatively contact (1) from lower from upper the 3rd screw rod (6), the 3rd spring (10), the 7th spring (14), the 3rd nut (18) used successively, and opposite side is fixed on initiatively contact (1) from lower from upper the 4th screw rod (7), the 4th spring (11), the 8th spring (15), the 4th nut (19) used successively.Initiatively contact (1) and for the first time moving contact (2), between moving contact (3), adopt double-spring structure to fix for the second time, utilize spring-compressed power and expansion force to guarantee that clamping power is evenly avoided the generation of virtual connection situation in long-term up and down wear process.
