According to the isolating ground switch used for the solid insulation switch cabinet provided by the utility model, three phases of the isolating ground switch are arranged on the main shaft through the three connecting levers and bending plates, thus the distance among the three phases can be adjusted freely without influence; the main shaft is matched with the connecting levers through the hexagonal shaft holes, so that the positions of the connecting levers on the main shaft can be easily adjusted in real time, in this way, the isolating ground switch can be easily matched with the breaker having a random phase spacing, therefore, the isolating ground switch of the utility model has good versatility, and simultaneously ensures synchronism of closing and opening of the three phases.
Description
Technical field
The utility model relates to the electric switch technical field, particularly a kind of isolation earthing switch for the solid insulation switch cabinet.
Background technology
The tradition isolation earthing switch all is three-phase integrated fixing, and the spaced apart of isolation earthing switch is fixed like this, and it can only be matched with the circuit breaker of corresponding spaced apart, so versatility is poor.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of spaced apart the adjustable isolation earthing switch that is used for the solid insulation switch cabinet.
The utility model is achieved in that provides a kind of isolation earthing switch for the solid insulation switch cabinet, comprises fixed contact, moving contact, moving contact bracing frame, grounding contact, bent plate, connecting lever and main shaft; Described moving contact is installed on the described moving contact bracing frame rotationally; One end of every mutually described moving contact and described bent plate is rotationally connected; One end of the other end of described bent plate and described connecting lever is rotationally connected; Be formed with six square shaft holes in the other end of described connecting lever; Described main shaft passes 3 described six square shaft holes on three described connecting levers.
Further, described main shaft is six square shafts.
Further, described grounding contact becomes an angle of 90 degrees to arrange with described fixed contact.
Compared with prior art, the three-phase of the isolation earthing switch that is used for the solid insulation switch cabinet in the utility model is installed in main shaft by three connecting levers and bent plate, and therefore, three alternate distances can freely be adjusted and be independent of each other; And, owing to be to cooperate by six square shaft holes between main shaft and connecting lever, therefore, the position of connecting lever on main shaft can be adjusted in real time, very easily regulates, and so just is easy to cooperate with the circuit breaker of any spaced apart, versatility is very good, can guarantee the synchronism of three-phase divide-shut brake simultaneously again.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.
Description of drawings
Fig. 1 is the schematic diagram that is used for the isolation earthing switch of solid insulation switch cabinet among the utility model one embodiment.
Fig. 2 is the side schematic view of Fig. 1.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Figure 1 shows that the schematic diagram that is used for the isolation earthing switch (being designated hereinafter simply as isolation earthing switch) of solid insulation switch cabinet among the utility model one embodiment.Fig. 2 is the side schematic view of Fig. 1.As shown in Fig. 1 and Fig. 2, the isolation earthing switch that is used for the solid insulation switch cabinet can comprise fixed contact 1, moving contact 2, moving contact bracing frame 3, grounding contact 4, bent plate 5, connecting lever 6 and main shaft 7.Wherein, moving contact 2 is installed in rotationally on the moving contact bracing frame 3 and by bent plate 5 and is connected with main shaft 7 with connecting lever 6, and main shaft 7 can drive the isolating switch closing position of moving contact 2 from contacting with fixed contact 1 with connecting lever 6 by bent plate 5, turn to the separating brake position, and further turn to the earthed switch closing position that contacts with grounding contact 4.
Particularly, fixed contact 1 can be formed on the body top cover inside of isolation earthing switch by modes such as casting.
Moving contact 2 can be installed on the moving contact bracing frame 3 rotationally by screw etc.
Grounding contact 4 is fixed on the body of isolation earthing switch.Grounding contact 4 becomes an angle of 90 degrees to arrange with fixed contact.
One end of the zone line of every phase moving contact 2 and bent plate 5 is rotationally connected; One end of the other end of bent plate 5 and connecting lever 6 is rotationally connected.Be formed with six square shaft holes 62 in the other end of connecting lever 6, be used for installing main shaft 7.
Main shaft 7 can be six square shafts.Main shaft 7 passes 3 six square shaft holes 62 on three connecting levers 6 successively, thereby the three-phase of isolation earthing switch is separately fixed on the main shaft 7, and therefore, three alternate distances can freely be adjusted and be independent of each other; And because main shaft 7 and 6 of connecting levers are to cooperate by six square shaft holes 62, therefore, the position of connecting lever 6 on main shaft 7 can be adjusted in real time, very easily regulates, and so just is easy to cooperate with the circuit breaker of any spaced apart, and versatility is very good.
Above-mentioned is the concrete structure that is used for the isolation earthing switch of solid insulation switch cabinet among the utility model one embodiment, its method of operation of brief description.
Utilizing transmission mechanism to drive main shaft 7 rotates; The rotation of main shaft 7 drives three moving contacts 2 around corresponding moving contact bracing frame 3 rotations by the rotation of connecting lever 6 and bent plate 5; When operating mechanism drive main shaft 7 clockwise directions rotation 60 is spent, main shaft 7 is by bent plate 5 and connecting lever 6 pulling moving contacts 2 clockwise directions rotation 45 degree, fixed contact 1 is left in the upper end rotation of moving contact 2, and moving contact 2 just forwards the separating brake position to from the isolating switch closing position.Continuation is towards the rotation of this direction, and moving contact 2 rotates 45 degree more forward, and the upper end rotating clamp of moving contact 2 is right after ground contact 4, and 2 of moving contacts forward the earthed switch closing position to by the separating brake position.When operating mechanism drove main shaft 7 rotation counterclockwise, moving contact 2 is rotation counterclockwise also, moving contact 2 will be by earthing position to the separating brake position again to closing position.
In sum, the three-phase that is used for the isolation earthing switch of solid insulation switch cabinet among the utility model one embodiment is installed in main shaft 7 by three connecting levers 6 and bent plate 5, and therefore, three alternate distances can freely be adjusted and be independent of each other; And, because main shaft 7 and 6 of connecting levers are to cooperate by six square shaft holes 62, therefore, the position of connecting lever 6 on main shaft 7 can be adjusted in real time, very easily regulates, and so just is easy to cooperate with the circuit breaker of any spaced apart, versatility is very good, can guarantee the synchronism of three-phase divide-shut brake simultaneously again.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
