Abstract
The utility model discloses a rapid grounding switch, which comprises a shell, a rapid grounding static contact, a rapid grounding dynamic contact, a turning arm and a hexagonal axis; the shell is arranged on a side flange interface of a right-angle three-position isolation switch; the rapid grounding static contact and the rapid grounding dynamic contact are connected with each other through a conductor which is arranged on the isolation switch; and the rapid grounding dynamic contact is supported in a horizontally axial position relative to the rapid grounding static contact through a support connecting structure, and is connected with a grounding plate outside the shell through the support connecting structure. The utility model changes the metal shell and internal structure of the original rapid grounding switch through arranging an insulation flange into the cavity formed by the shell of the rapid grounding switch, and a novel external insulation flange is designed. Therefore, the utility model realizes the combination of the rapid grounding switch with the side end of the GR type three-position isolation switch; and further expands the interface of the GR type three-position isolation switch.
Description
Technical field
The utility model relates to and being used in a kind of gas-insulated switchgear (GIS) and the compound high speed grounding switch of GR type (perpendicular type) tri-station isolating switch.
Background technology
General GIS with high speed grounding switch when being used with GR type tri-station isolating switch, about high speed grounding switch and GR type tri-station isolating switch are loaded on respectively in two metal shells, and separate by insulating basin, make both become separate switch element (Fig. 1).Such structure makes GR type tri-station isolating switch be merely able to use two flange-interfaces of right side and bottom side at most, and makes two other flange-interface idle.It is not only bulky, it is inconvenient to install, and makes the connecting mode of GR type tri-station isolating switch can't flexible arrangement (as can not vertical duction be connected with miscellaneous part).
Summary of the invention
The purpose of this utility model is on the basis that guarantees realization GR type tri-station isolating switch and the original breaking-closing operating function of high speed grounding switch, provide a kind of structure that can be used for the compound high speed grounding switch of GR type tri-station isolating switch, with the connected mode of expansion perpendicular type isolating switch interface.
In order to achieve the above object, the utility model takes following technical scheme to be achieved:
A kind of high speed grounding switch comprises housing, quick ground connection fixed contact, quick ground connection moving contact, connecting lever, six square shafts, it is characterized in that described case side is loaded on the perpendicular type tri-station isolating switch one side flange interface; Described quick ground connection fixed contact and static contact isolation switch link together by a conductor that is installed on the isolating switch; Described quick ground connection moving contact is supported on the horizontal axis position of ground connection fixed contact relatively fast by a support and connection structure, and is connected to the ground plate of outside by this support and connection structure.
In the such scheme, described support and connection mechanism comprises that one is fixed in the inner chamber insulating flange of housing vertical axial position and self-reliance contact, the radome of horizontal axis, this inner chamber insulating flange is provided with the center inserts that connects quick ground connection moving contact, this center inserts is connected to the center conductor that is arranged on housing top exterior insulation flange by the inner chamber ground plate, and this center conductor is connected with the ground plate of outside.
Described six square shafts, connecting lever and connecting plate with connect the moving contact tail end fast and be connected, and place in the same housing.
The utility model is by changing the metal shell and the internal structure of original high speed grounding switch, insulating flange is placed in the high speed grounding switch housing chamber, and design novel exterior insulation flange, realized the compound GR of the placing type of high speed grounding switch tri-station isolating switch housing side, thereby expanded the interface of GR type tri-station isolating switch, not only connected mode more flexibly, structural configuration is abundant and diversified more to make GR type tri-station isolating switch, and owing to removed insulating basin, saved material cost, volume is smaller and more exquisite simultaneously.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
As Fig. 2, shown in Figure 3, a kind of high speed grounding switch comprises housing 5, ground connection fixed contact 13, ground connection moving contact 8, connecting lever 6, connecting rod 7 and six side's rotating shafts 2 fast fast.Housing 5 sides are loaded on the perpendicular type tri-station isolating switch one side flange interface 16; Ground connection fixed contact 13 links together by a conductor 14 that is installed on the isolating switch with static contact isolation switch 15 fast; The ground connection moving contact is supported on the horizontal axis position of ground connection fixed contact 13 relatively fast by the inner chamber insulating flange 10 that is fixed in housing horizontal axis position fast.The inner chamber insulating flange is provided with the center inserts 11 that connects quick ground connection moving contact 8, and this center inserts is connected to the center conductor 12 that is arranged on the housing top exterior insulation flange 3 by inner chamber ground plate 9, and this center conductor is electrically connected with the ground plate 4 of outside.Drive high speed grounding switch seal shaft 1 by spring operating mechanism, make its clockwise direction drive six side's rotating shafts 2, thereby drive connecting lever 6 and connecting rod 7, drive quick ground connection moving contact 8 and travel forward, realize the closing operation of high speed grounding switch.Otherwise, drive high speed grounding switch seal shaft 1 by spring operating mechanism, make it counterclockwise drive six side's rotating shafts 2, thereby drive connecting lever 6 and connecting rod 7, drive quick ground connection moving contact 8 and move backward, realize the sub-switching operation of high speed grounding switch.
When from high speed grounding switch measurement major loop resistance, remove external floor 4, by the center conductor on the exterior insulation flange 3 12, to inner chamber ground plate 9, by the center inserts 11 of inner chamber insulating flange 10, be connected to quick ground connection moving contact 8, again to conductor 14 again.
The high speed grounding switch of present embodiment is loaded on the flange-interface 16 of GR type tri-station isolating switch one side owing to side, realized a flange inlet wire of GR type tri-station isolating switch, two flange outlets farthest utilize and have expanded GR type tri-station isolating switch.
