Abstract
The utility model belongs to a three-position movable contact base assembling structure for box-type gas insulated metal-enclosed switchgears, and the three-position movable contact base assembling structure mainly comprises a movable contact base body and a shielding cover, wherein one end of the movable contact base body is provided with a watchband contact finger base, the other end of the movable contact base body is provided with a through hole which penetrates through the middle part of the watchband contact finger base, and two split contact base bodies and the two sides of the movable contact base body are connected together through bolts. The outer side of each split contact base body is provided with a blossom contact finger, the outer wall of the blossom contact finger is hooped with a spring, and the spring is wrapped with the shielding cover. According to the utility model, the number and volume of the movable contact base are reduced by adopting a combined structure, so that the assembling structure disclosed by the utility model has the advantages of simple structure, small compact volume, simple wiring, less machining process, rapid machining speed, safety and reliability, good electrical conductivity, low cost and long service life.
Description
Technical field
The utility model belongs to a kind of box type gas insulated metal sealing switchgear three station moving contact seat assembly structures.
Background technology
The moving contact seat of traditional box type gas insulated metal sealing switchgear is three split absolute construction, causes moving contact seat shared volume in this combined electrical apparatus large, poor stability, and complex structure, connecting wiring is mixed and disorderly, and cost is high, affects its normal use.
Summary of the invention
The purpose of this utility model is a kind of box type gas insulated metal sealing switchgear three station moving contact seat assembly structures of design, adopt quantity and the volume of combining structure reduction moving contact seat, have simple in structure, compact volume is little, and wiring is simple, and manufacturing procedure is few, process velocity is fast, safe and reliable, it is electrically good to conduct electricity, and cost hangs down the advantage with long service life.
For this reason, the utility model mainly is comprised of movable contact pedestal and radome, and movable contact pedestal one end is the watchband-shaped contactor seat, and the movable contact pedestal other end is the through hole that connects with watchband-shaped contactor seat middle part, and two split touch base bodies are connected with movable contact pedestal both sides by screw.The external side of described split touch base is provided with the plum blossom fingertip, and hoop is provided with spring on the plum blossom fingertip outer wall, and the spring outsourcing is provided with radome.The said structure design has realized the purpose of this utility model.
The utility model adopts combining structure to reduce quantity and the volume of moving contact seat, and the quantity of having reduced moving contact seat is 50%, reduction in bulk 80%, cost 40%.Have simple in structurely, compact volume is little, and wiring is simple, and manufacturing procedure is few, and process velocity is fast, and is safe and reliable, and it is electrically good conduct electricity, the low advantage with long service life of cost.
Description of drawings
Figure is structural representation of the present utility model.
Embodiment
As shown in the figure, a kind of box type gas insulated metal sealing switchgear three station moving contact seat assembly structures mainly are comprised of movable contact pedestal 3 and radome 4.Movable contact pedestal one end is watchband-shaped contactor seat 1, and the movable contact pedestal other end is the through hole that connects with watchband-shaped contactor seat middle part.Two split touch base bodies 8 are connected with movable contact pedestal both sides by screw 7.The external side of described split touch base is provided with plum blossom fingertip 6, on the plum blossom fingertip outer wall hoop be provided with spring 5, the spring outsourcing is provided with radome, radome can wrap establish extend to the split touch base external after and the movable contact pedestal fix.
During use, pass through hole with hexagon socket head cap screw 2 after a conductor plug (dotted line part among the figure) inserts on the watchband-shaped contactor seat and fix with it.Can insert respectively admittedly other two conductor plugs on the two split touch base bodies.Can conveniently finish connection.
In a word, the utility model adopts quantity and the volume of combining structure reduction moving contact seat, has simple in structurely, and compact volume is little, and wiring is simple, and manufacturing procedure is few, and process velocity is fast, and is safe and reliable, and it is electrically good conduct electricity, the low advantage with long service life of cost.
