Abstract

The invention discloses a combination right-angle isolating switch with a rapid ground switch, comprising a right-angle isolating switch part and a rapid ground switch part; the switch is characterized in that: the rapid ground switch part is combined with the right-angle isolating switch part in a same shell through the flange interface at one level side of the isolating switch shell, and connects the fixed contact of the rapid ground switch with a fixed contact of an isolating switch through a conductor; the conductor is vertically arranged on the flanged interface on upper and lower ends of the isolating switch shell. The invention compositely places the rapid ground switch at the side end of the GR type isolating switch shell, thereby enlarging the interface of the GR type isolating switch, so as to cause the connecting mode of the GR type isolating switch to be more flexible, has more plenty and diversified structure arrangement; because a base type insulator is removed, which saves material cost and has cabinet volume.

Description

The composite perpendicular type isolating switch of band high speed grounding switch

Technical field

The present invention relates to GR type (perpendicular type) isolating switch of a kind of GIS (Cubicle Gas-Insulated Switchgear) with the band high speed grounding switch.

Background technology

About general GIS is loaded on respectively with GR type isolating switch, high speed grounding switch in two metal shells, and separate, make both become separate switch element (Fig. 1) by insulating basin.Such structure makes GR type isolating switch be merely able to use two flange-interfaces on bottom side and right side, and makes the flange-interface in two other upside and left side idle.It is not only bulky, it is inconvenient to install, and makes the connecting mode of GR type isolating switch can't flexible arrangement (as can not vertical duction be connected with miscellaneous part).

Summary of the invention

The objective of the invention is provides a kind of composite perpendicular type isolating switch of band high speed grounding switch of extensive interface connected mode on the basis that guarantees realization GR type isolating switch and the original branch of high speed grounding switch, closing operation function.

For achieving the above object, the present invention takes following technical scheme to be achieved:

A kind of composite perpendicular type isolating switch with high speed grounding switch; Comprise perpendicular type isolating switch part and high speed grounding switch part; It is characterized in that; Said high speed grounding switch part partly is compounded in the same housing through flange-interface and the perpendicular type isolating switch of isolating switch housing level one side, and the fixed contact of high speed grounding switch and a fixed contact of isolating switch are linked together through conductor, and this conductor is vertically set on the flange-interface at two ends about the isolating switch housing.

In the such scheme, the fixed contact of said high speed grounding switch is the plum blossom fixed contact of a band radome, and this plum blossom fixed contact is connected the conductor middle part of static contact isolation switch one side dorsad through a contact base; The moving contact of high speed grounding switch is supported in the horizontal axis position of relative plum blossom fixed contact through a support and connection structure.Said support and connection structure comprises an inner chamber insulating flange that is fixed in housing vertical axial position; This inner chamber insulating flange is provided with the center inserts of the quick ground connection moving contact of support and connection, and the inner chamber insulating flange is connected on the center conductor that is arranged on high speed grounding switch housing top exterior insulation flange through an inner chamber ground plate.The moving contact tail end of said high speed grounding switch directly is connected with the basic operating mechanism that places in the same high speed grounding switch housing.

Compared with prior art; The present invention is with the compound GR type isolating switch housing side that places of high speed grounding switch; Thereby expanded the interface of GR type isolating switch, not only connected mode more flexibly, structural configuration is abundant and diversified more to make GR type isolating switch, and owing to removed a disc insulator; Practiced thrift material cost, volume is smaller and more exquisite simultaneously.

Embodiment

Below in conjunction with the description of drawings embodiments of the invention.

Fig. 2 representes internal structure of the present invention, in this example, through bolt 8 isolating switch housing 19 is connected with high speed grounding switch housing 14, and making GR type Disconnecting switch unit and high speed grounding switch unit organically compound is a unit.

In Fig. 2, kept all functions of original isolating switch, earthed switch fixed contact 2 is linked to each other with center inserts on the insulating flange 1 through bolt, isolating switch moving contact 5 places on the conductor 4, and conductor 4 is installed on the disc insulator 3.Static contact isolation switch 6 all places on the conductor 7 with quick ground connection fixed contact 9.When isolating switch moving contact 5 mediated, when promptly not inserting among static contact isolation switch 6 or the earthed switch fixed contact 2, isolating switch was grounded the function that switch branch-isolating switch divides; When isolating switch moving contact 5 moves upward, when inserting among the earthed switch fixed contact 2, isolating switch is grounded switch and closes-function that isolating switch divides; When isolating switch moving contact 5 moves downward, when inserting among the static contact isolation switch 6, isolating switch is grounded the function that switch branch-isolating switch closes.

In Fig. 2, in order to realize deciliter function of high speed grounding switch, increase by a contact base at a middle side part of conductor 7 opposing static contact isolation switches 6, be used to install the fixed contact of high speed grounding switch, this fixed contact is the plum blossom fixed contact 9 of band radome.Ground connection moving contact 13 is supported on the horizontal axis position of relative plum blossom fixed contact 9 through a support and connection structure 18 fast; Said support and connection structure 18 comprises an inner chamber insulating flange that is fixed in housing vertical axial position; This inner chamber insulating flange is provided with the center inserts of the quick ground connection moving contact 13 of support and connection; This center inserts is connected on the center conductor 15 that is arranged on high speed grounding switch housing 14 top exterior insulation flanges 16 through inner chamber ground plate 17; The tail end of ground connection moving contact 13 directly is connected with connecting rod 12 and connecting lever 11 fast, and connecting rod 12 is connected through pin with connecting lever 11, and connecting lever 11 is fixed in six side's rotating shafts 10 simultaneously.Counterclockwise drive six side's rotating shafts 10 through spring operating mechanism, thereby drive connecting lever 11 and connecting rod 12, drive quick ground connection moving contact 13 and travel forward, be inserted in the Mume flower contact device 9, realize the closing operation of high speed grounding switch.Otherwise clockwise direction drives six side's rotating shafts 10, thereby drives connecting lever 11 and connecting rod 12, drives quick ground connection moving contact 13 and moves backward, leaves Mume flower contact device 9, realizes the sub-switching operation of high speed grounding switch.
