Abstract
The utility model provides a three-position switch, which comprises a grounding contact and a turn-on contact which are mounted on a housing and also comprises a disconnector; the disconnector comprises a disconnector support piece, a transmission system and a contact rod; the disconnector support piece comprises a support arm mounted on the housing and a slide cylinder mounted at a top end of the support arm; the transmission system comprises a rack-and-pinion; the contact rod is slidably plugged in the slide cylinder, one end of the contact rod is corresponding to the grounding contact, and the other end of the contact rod is corresponding to the turn-on contact; and the contact rod and a rack of the rack-and-pinion are integratedly manufactured, and the pinion of the rack-and-pinion is mounted on the support arm. The beneficial effects are that: an operating mechanism is adopted for three-phase linkage drive, and three working conditions of turn-on, isolation and grounding are realized; the three-position switch has the capability of opening and closing a bus to convert current, inductive current and capacitive current; and the three-position switch is compact and concise in structure and reliable in performance, improves product standardization degree and reduces product cost.
Description
Technical field
The utility model belongs to SF
6Cubicle Gas-Insulated Switchgear (GIS) isolation, ground connection unit switch relate to a kind of three-station.
Background technology
Present stage, isolation ground connection unit switch in 110kV gas-insulated metal-enclosed switchgear (GIS) is each and drives with an operating mechanism, realize the action of isolation and earthed switch, only has electrical interlock both, there is no mechanical interlocking, can't realize High-Voltage Electrical Appliances " five is anti-" specification requirement fully.Mechanism's quantity is many, and project organization is complicated, the processing and manufacturing cost is high, and product competitiveness is poor.
Summary of the invention
The utility model provides a kind of three-station simple in structure, esy to use, safe and reliable in order to make up the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
three-station of the present utility model, comprise the grounding contact that is arranged on housing and make contact, also comprise isolating switch, its special character is: isolating switch comprises the isolating switch supporter, drive system and feeler lever, the isolating switch supporter comprises the support arm that is arranged on housing and is arranged on the slide cartridge on support arm top, drive system comprises rack-and-pinion, the feeler lever sliding plug is inner at slide cartridge, feeler lever one end is corresponding with grounding contact, the other end with make contact corresponding, the tooth bar of feeler lever and rack-and-pinion is made into integration, the gear of rack-and-pinion is arranged on support arm.
Three-station of the present utility model, preferred version are that grounding contact, feeler lever and the three that makes contact are positioned on the same angled straight lines.
The beneficial effects of the utility model are, in this product, the three-station of compact conformation is driven by an operating mechanism three-phase ganged, forward and backward by actuating unit drives drive system through the conversion of gear, tooth bar, complete feeler lever in the reciprocating motion of connecting between three isolated or three-phase grounds, can realize connection, isolation, three kinds of operating modes of ground connection.Ability with opening-closing bus switching current and perception, capacity current.Not only compact conformation is succinct for this product, dependable performance, and can be used as the unitization design that standard module is realized 110kVGIS.Realize the mechanical interlocking of isolating switch and earthed switch in 110kVGIS, simplified product structure, improved the degree of product standardization, reduced mechanism's quantity, reduced product cost, strengthened product competitiveness.This design is mainly used in 110kV Cubicle Gas-Insulated Switchgear (GIS) isolation, earthed switch.
Description of drawings
Fig. 1 is former isolation ground connection unit switch cutaway view.Fig. 2 is the outline drawing of Fig. 1.Fig. 3 is this novel three-station structure chart.
In figure: 1 earthed switch, 2 isolating switch supporters, 3 drive systems, 4 isolating switches, 5 interrupters, 6 earthing mechanisms.7 grounding contacts, 8 make contact, 9 feeler levers, 10 support arms, 11 slide cartridges, 12 rack-and-pinions.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
three-station of the present utility model, comprise the grounding contact 7 that is arranged on housing and make contact 8, also comprise isolating switch, isolating switch comprises the isolating switch supporter, drive system and feeler lever 9, the isolating switch supporter comprises the support arm 10 that is arranged on housing and the slide cartridge 11 that is arranged on the support arm top, drive system comprises rack-and-pinion 12, feeler lever 9 sliding plugs are in slide cartridge 11 inside, feeler lever one end is corresponding with grounding contact 7, the other end with make contact 8 corresponding, the tooth bar of feeler lever and rack-and-pinion is made into integration, the gear of rack-and-pinion is arranged on support arm 10.Grounding contact 7, feeler lever 9 and 8 threes that make contact are positioned on the same angled straight lines.
Three-station of the present utility model, driven by an operating mechanism three-phase ganged, forward and backward by actuating unit drives drive system through the conversion of gear, tooth bar, complete feeler lever 9 connect A, B, C three is isolated or A, B, C three-phase ground between reciprocating motion, can realize connection, isolation, three kinds of operating modes of ground connection.Ability with opening-closing bus switching current and perception, capacity current.This product can be used as the unitization design that standard module is realized 110kVGIS, has realized the mechanical interlocking of isolating switch and earthed switch in 110kVGIS, is mainly used in that 110kV Cubicle Gas-Insulated Switchgear (GIS) is isolated, earthed switch.
