Description
Technical field
The utility model relates to the indoor high-voltage isolating switch in a kind of electric power power transmission and transformation system.
Background technology
Indoor high-voltage isolating switch is used for switching under the high-tension line current-carrying situation in the electric power power transmission and transformation system and the electric equipments such as high voltage bus circuit breaker that overhauled is carried out the electrical equipment isolation with charged high-tension line.In the power transmission and transformation system of rated voltage 12kV three-phase alternating current 50Hz, public isolating switch is a contact knife formula isolating switch at present.This mounting means makes the switch cubicle volume bigger, and the interlock complexity increases complete workload, and operation sequence is loaded down with trivial details.Along with the upgrading of High-Voltage Electrical Appliances original paper, being extensive use of of the particularly appearance of permanent magnetic actuator vacuum circuit breaker, and SF6 on-load switch requires the fixed high-voltage switch cubicle structure compact more, miniaturization more.Existing isolating switch can not satisfy this requirement.
The utility model content
The purpose of this utility model is the needs that adapt to the box switch cubicle of compact and " handing in hand " electric power system, designs a kind of miniaturization indoor high-voltage Direct Action Type isolating switch.
The technical solution of the utility model is, a kind of indoor high-voltage Direct Action Type isolating switch, it is characterized in that, be fixed with two insulation contact bearings on the pedestal, be fixed with upper contact head and following contact on two insulation contact bearings respectively, be fixed with guide cylinder between upper contact head and the following contact, slip cap is equipped with the metal cylinder moving conductive rod of hollow in the guide cylinder, upper contact head, following contact and moving conductive rod have common center line, be connected with circular spring contact strip in upper contact head and the following contact, moving conductive rod passes spring contact strip and is connected with following contact with upper contact head by sliding contact, and the leading electric part of common formation; One rotating shaft is arranged between two insulation contact bearings on the pedestal, be fixed with an insulation guide post in the rotating shaft, the insulation guide post is connected by insulated tension pole with moving conductive rod, and insulated tension pole can be done the piston type back and forth movement under the drive of insulation guide post.
The indoor high-voltage Direct Action Type isolating switch that the utility model provides is compared with existing contact knife formula swing arm isolating switch, and operating physical force is little, and compact conformation is small and exquisite, weight saving, thus make the switch cubicle volume-diminished.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the utility model indoor high-voltage Direct Action Type isolating switch.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, insulation contact bearing 2, upper contact head 3, spring contact strip 4, guide cylinder 5, moving conductive rod 6, contact 7, pedestal 8, insulated tension pole 9, insulation guide post 10, rotating shaft down
As shown in drawings, the utility model indoor high-voltage Direct Action Type isolating switch is fixed with two insulation contact bearings 1 on pedestal 7, be fixed with upper contact head 2 and following contact 6 on two insulation contact bearings 1 respectively, be fixed with guide cylinder 4 between upper contact head 2 and the following contact 6, slip cap is equipped with the metal cylinder moving conductive rod 5 of hollow in the guide cylinder 4, upper contact head 2, following contact 6 and moving conductive rod 5 have common center line, be connected with circular spring contact strip 3 in upper contact head 2 and the following contact 6, moving conductive rod 5 passes spring contact strip 3 and is connected with following contact 6 with upper contact head 2 by sliding contact, and the leading electric part of common formation; One rotating shaft 10 is arranged between two insulation contact bearings 1 on the pedestal 7, be fixed with an insulation guide post 9 in the rotating shaft 10, insulation guide post 9 is connected by insulated tension pole 8 with moving conductive rod 5, and insulated tension pole 8 can be done the piston type back and forth movement under the drive of insulation guide post 9.
When rotating shaft 10 is rotated, drive insulation guide post 9 with its motion, insulated tension pole 8 is done the piston type back and forth movement under insulation guide post 9 drives; Insulated tension pole 8 also will drive moving conductive rod 5 and do rectilinear motion up and down along common center line.When rotating shaft 10 clockwise the time, insulated tension pole 8 drives moving conductive rods 5 straight lines and rises and contact the realization combined floodgate with the inner upper contact head 2 that is connected with spring contact strip 3; Otherwise, separating brake.
