Abstract
The utility model relates to a small rotary disconnecting switch which comprises a switch base frame, a sleeve and an insulator, wherein a conducting pipe is arranged in the sleeve, and a static contact is arranged on the insulator. The rotary disconnecting switch is characterized in that an epoxy resin sleeve is arranged on the switch base frame; epoxy resin insulators are respectively arranged on the both sides of the epoxy resin sleeve on the switch base frame, and are fixed on the upper and lower surfaces of the switch base frame; the upper surface and lower surface of the switch base frame are separated through a partition board fixed on the switch base frame; a bevel gear is also arranged on one side of the switch base frame; the switch-on and the switch-off of the switch can be realized through rotating contacts; and because the contacts are respectively installed on the upper and the lower surfaces of the switch base frame, the energized part is completely insolated from the current-less part in a switch cabinet, the moving contact after being disconnected is directly grounded, and the personal safety during the maintenance is assured. The rotary disconnecting switch has the advantages of small volume and good insulation strength and mechanical strength.
Description
Technical field
The utility model relates to a kind of indoor high-voltage isolating switch, particularly relate to a kind of minitype high voltage rotary isolation switch that rotates the contact knife formula, it is improvement to existing isolating switch structure, belong to the isolating switch manufacturing technology, be applicable to rated voltage 12kV, exchange in the three-phase electrical power system of 50Hz, connect under the uncharge situation of voltage and the conversion line use, mainly be installed in the metal enclosed fixed switchgear of armouring of miniaturization as having.
Background technology
Connect and indoor high-voltage isolating switch that conversion line uses as having under the uncharge situation of voltage, in rated voltage 12kV, in the three-phase electrical power system of interchange 50Hz.At present, existing indoor high-voltage isolating switch, GN30-12 type for example, insulation adopt porcelain bushing and ceramic insulator, the ubiquity volume is big, dielectric strength and the relatively poor shortcoming of mechanical strength.
The utility model content
The purpose of this utility model just is to overcome the prior art above shortcomings, provide a kind of minitype high voltage rotary isolation switch, this novel minitype high voltage rotary isolation switch is a kind of novel isolating switch that rotates the contact knife formula, adopt epoxy resin bushing and insulator, the volume of product is reduced, realized miniaturization; Also adopted the bevel gear steering operation, safe and reliable, flexible operation has that volume is little, dielectric strength and good characteristics of mechanical strength.
The technical solution that the utility model provides is: this minitype high voltage rotary isolation switch, include the switch underframe, sleeve pipe and insulator, in its middle sleeve contact tube is housed, insulator is provided with fixed contact, be characterized in that described switch underframe is provided with epoxy resin bushing, the both sides of the epoxy resin bushing on the switch underframe are equipped with insulator, this insulator is fixed on the switch underframe, on following two faces, on the switch underframe, separate by the dividing plate that is fixed on the switch underframe between following two faces, also be provided with bevel gear on one side of described switch underframe, by the rotation contact knife, thus the combined floodgate of realization switch, separating brake.Because contact is installed in respectively on the upper and lower surfaces of switch underframe, make its live part and currentless part in switch cubicle, separate fully, the direct ground connection of the moving contact after the disconnection, thereby the personal safety when having guaranteed to keep in repair.
When the utility model is installed on the side dress breaker cabinet, but direct control isolating switch main shaft.If can be used by bevel gear or connecting rod and various interlocking gear when being installed on the armouring sealing stationary cabinet.
Compared with prior art, the beneficial effects of the utility model are: adopt epoxy resin bushing and insulator, the volume of product is reduced, realized miniaturization; Also adopted the bevel gear steering operation, safe and reliable, flexible operation has that volume is little, dielectric strength and good characteristics of mechanical strength.

Fig. 1 is the structural representation of the embodiment that provides of the utility model;
Fig. 2 be the embodiment that provides of the utility model combined floodgate, gate-dividing state schematic diagram.
Embodiment
Below in conjunction with embodiment concrete technical scheme of the present utility model is described further:
As Fig. 1～shown in Figure 2, this minitype high voltage rotary isolation switch, include switch underframe 4, sleeve pipe and insulator, in its middle sleeve contact tube is housed, insulator is provided with fixed contact, be characterized in that described switch underframe 4 is provided with epoxy resin bushing 1, the both sides of the epoxy resin bushing 1 on the switch underframe 4 are equipped with insulator 2, this insulator is fixed on the switch underframe 4, on following two faces, on the switch underframe 4, separate by the dividing plate that is fixed on the switch underframe 4 between following two faces, also be provided with bevel gear 3 on one end of described switch underframe 4, by the rotation contact knife, thus the combined floodgate of realization switch, separating brake.Because contact is installed in respectively on the upper and lower surfaces of switch underframe 4, make its live part and currentless part in switch cubicle, separate fully, the direct ground connection of the moving contact after the disconnection, thereby the personal safety when having guaranteed to keep in repair.
Epoxy resin bushing 1 solid line among the figure partly is a closing position, and epoxy resin bushing 1 dotted portion is the isolated location.
In the epoxy resin bushing 1 contact tube is housed,, makes 1 swing of its epoxy resin bushing by operation bevel gear 3, reach with epoxy resins insulation 2 on fixed contact contact and separate, play that Circuits System is connected and the effect of isolating.
