The technical scheme that the utility model adopts is: a kind of three station isolation earthing switch; Comprise the moving contact seat assembling that is arranged on middle part in the housing and the isolation touch base assembling that is separately positioned on both sides in the housing and the assembling of ground connection touch base; The insulating contact of isolating the touch base assembling is installed on the disk insulator through contact base; The grounding contact of ground connection touch base assembling is installed on the ground connection handle through contact base; The moving contact of moving contact seat assembling is installed on the supporting seat through moving contact seat, and moving contact is connected with mechanism through transmission device, and described insulating contact and grounding contact are Mume flower contact; Described moving contact is provided with tooth bar; The moving contact outside is covered with radome, and radome and moving contact seat are dynamically connected till moving contact and the moving contact seat for being fixedly connected; Moving contact seat is provided with groove; The drive link of transmission device stretches in this groove, and the end of drive link is provided with gear, and this gear is meshed with the tooth bar of moving contact.
Contact in the middle of between moving contact and radome, also being provided with, this centre contact is a tubular, middle contact is connected with moving contact seat through the flange of end.
Also be provided with fairlead at the moving contact seat inner side.
The utility model is provided with tooth bar on moving contact; Drive link at transmission device extend in the groove of moving contact seat gear, and mechanism rotates through the transmission device driven gear like this, the wheel and rack engagement; Drive moving contact and do straight reciprocating motion; Thereby realize the reciprocating action of moving contact between centre position-isolation-ground connection, and moving contact can only be parked in one of them position, avoid the generation of malfunction; Be the rack-and-pinion transmission between transmission device and the moving contact, this structure guarantees that transmission is stable, and transmission efficiency is high, reliable in action; Fixed contact of the utility model and grounding contact are the Mume flower contact formula, and Mume flower contact is simple in structure, and dependable performance is easy for installation.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Embodiment
Combine accompanying drawing that the utility model is further described at present; Fig. 1 is a kind of embodiment of the utility model; Comprise moving contact seat 1 assembling and isolation touch base assembling that is separately positioned on both sides in the housing and the assembling of ground connection touch base that are arranged on middle part in the housing; The insulating contact 2 of isolating the touch base assembling is installed on the disk insulator through contact base, and the grounding contact 6 of ground connection touch base assembling is installed on the ground connection handle through contact base, and the moving contact 3 of moving contact seat 1 assembling is installed on the supporting seat through moving contact seat 1; Moving contact 3 is connected with mechanism through transmission device, and mechanism is an electric operating mechanism usually.Described insulating contact 2 is Mume flower contact with grounding contact 6, and Mume flower contact has simple in structure, dependable performance, convenient installation.Described moving contact 3 is provided with tooth bar, and moving contact 3 outsides are covered with radome 7, and radome 7 and moving contact seat 1 be for being fixedly connected, and is dynamically connected till moving contact 3 and the moving contact seat 1, and promptly moving contact 3 flexibly connects with moving contact seat 1 within the specific limits.Moving contact seat 1 is provided with groove; The drive link of transmission device stretches in this groove; The end of drive link is provided with gear 10; This gear 10 is meshed with the tooth bar of moving contact 3, and moving contact 3 can be done straight reciprocating motion in radome 7 inside above moving contact seat 1 under the drive of transmission device and gear 10.
In the present embodiment, contact 8 in the middle of between moving contact 3 and radome 7, also being provided with, this centre contact 8 is a tubular, and middle contact 8 is connected with moving contact seat 1 through the flange of end, and the effect of middle contact 8 is to be moving contact 3 guide and limits.In the present embodiment, also be provided with fairlead in moving contact seat 1 inboard, the effect of fairlead is to be moving contact 3 guiding.
During use, mechanism rotates through the driving leading screw of transmission device, and leading screw drives drive nut and does rectilinear motion; Drive nut rotates through the drive link that bearing pin promotes to extend in moving contact seat 1 groove; Drive link drives moving contact 3 moving linearlies through the gear 10 of end, and transmission device of the utility model and moving contact 3 adopt the rack-and-pinion transmission, and this drive mechanism guarantees that transmission is stable; Transmission efficiency is high, reliable in action.The utility model is through the straight reciprocating motion of the rotating realization moving contact 3 of control motor, thus three service positions of realizing moving contact 3: the closing position that the isolated switch main fracture is connected, the centre position that main fracture separates and the earthing position of ground connection side.Through the design of this three stations, isolating switch and two elements of earthed switch are merged into an element, because the shared moving contact 3 of isolating switch and earthed switch, moving contact 3 can only be parked in a position, has avoided the generation of malfunction from structure.This structure is not only arranged compact more, and does not need the electrical interlocks and the mechanical chain of the outside of isolating switch and earthed switch, has simplified the logical relation of motion with control, makes operation more simple and reliable.
This shows that the utlity model has simple and reasonable for structurely, transmission is stable, the characteristics of reliable in action.
