Abstract
The utility model discloses an outdoor high-voltage direct-acting isolation switch which comprises a base, a shell, a circuit board on the base and a basic frame. The circuit board is connected with the basic frame. The circuit board is externally provided with a cover. A top of the shell is provided with mesh holes and a curved cover. An air hole is arranged at a connection position of the curved cover and the shell. The basic frame is fixed with two insulating contact bearings which are respectively fixed with an upper contact and a lower contact. A guide cylinder is fixed between the upper contact and the lower contact. A hollow metal cylinder body moving conducting rod is slidingly arranged in the guide cylinder. The upper contact, the lower contact and the moving conducting rod share a common center line. The upper contact and the lower contact are internally fixedly connected with round spring contact pieces. The moving conducting rod passes through the spring contact pieces and is connected with the upper contact and the lower contact through sliding contact to form a main conducting part together.
Description
Technical field
The utility model relates to the outdoor high-voltage isolating switch in a kind of electric power power transmission and transformation system.
Background technology
Outdoor 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 interlock is complicated, increases complete workload, and operation sequence is loaded down with trivial details.Along with the upgrading of High-Voltage Electrical Appliances original paper, being widely used 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 the 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 outdoor high-voltage Direct Action Type isolating switch.
The technical scheme of the utility model is, a kind of outdoor high-voltage Direct Action Type isolating switch comprises pedestal, shell, and wiring board on the pedestal and pedestal, and said wiring board is connected with pedestal, and the outer setting of wiring board has guard shield; Reticulated cell is arranged at the top of said shell, and the arc lid is arranged at the top, and there is the wind hole junction between arc lid and the shell; Be fixed with two insulation contact bearings on the said pedestal; Be fixed with upper contact head and following contact on two insulation contact bearings respectively; Upper contact head is fixed with guide cylinder with asking of following contact; Slip cap is equipped with the metal cylinder moving conductive rod of hollow in the guide cylinder, and upper contact head, following contact and moving conductive rod have common center line, are 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 through 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.
The outdoor 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
Fig. 1 is the structural representation of the utility model outdoor high-voltage Direct Action Type isolating switch.
Embodiment
A kind of outdoor high-voltage Direct Action Type isolating switch comprises pedestal 1, shell 2, and wiring board on the pedestal 13 and pedestal 4, and said wiring board 3 is connected with pedestal 4, and the outer setting of wiring board 3 has guard shield 5; Reticulated cell 6 is arranged at the top of said shell 2, and arc lid 7 is arranged at the top, and there is wind hole 8 junction between arc lid and the shell; Be fixed with two insulation contact bearings on the said pedestal 4; Be fixed with upper contact head and following contact on two insulation contact bearings respectively; Upper contact head is fixed with guide cylinder with asking of following contact; Slip cap is equipped with the metal cylinder moving conductive rod of hollow in the guide cylinder, and upper contact head, following contact and moving conductive rod have common center line, are 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 through 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.
When rotating shaft is rotated, drive the insulation guide post and move with it, insulated tension pole is done the piston type back and forth movement under the insulation guide post drives; Insulated tension pole also will drive moving conductive rod and do rectilinear motion up and down along common center line.When rotating shaft was clockwise, insulated tension pole drove the rising of moving conductive rod straight line and contacts with the inner upper contact head that is connected with spring contact strip, realizes closing a floodgate; Otherwise, separating brake.
