Abstract
Disclosed in the utility model is an intelligent high-voltage directly operated type isolating switch that comprises a substrate, a housing, a circuit board, and a frame, wherein the circuit board and the frame are arranged on the substrate. The circuit board is connected with the frame; a shield is arranged outside the circuit board; and an intelligent device is arranged on the circuit board. Meshed holes and an arc cover are arranged at the top of the housing; and wind outlets are arranged at connecting positions between the arc cover and the housing. According to the utility model, compared with the existing contact knife type swing-arm isolating switch, the provided intelligent high-voltage directly operated type isolating switch has advantages of small operating force, compact, small and exquisite structure, and light weight, so that the volume of the switch cabinet body is reduced. In addition, the intelligent device enables effective detection, early warning and circuit control to be realized.
Description
Technical field
The utility model relates to the intelligent high-pressure isolating switch in a kind of electric power power transmission and transformation system.
Background technology
High voltage isolator 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; The technical scheme of designing the high the utility model of a kind of miniaturized intelligent is; A kind of intelligent high-pressure Direct Action Type isolating switch comprises pedestal, shell, and wiring board on the pedestal and pedestal; Said wiring board is connected with pedestal, the outer setting straightening dynamic formula isolating switch of wiring board.
Guard shield is arranged, and wiring board is provided with intelligent apparatus; 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; 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, 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; Said intelligent apparatus comprises a microprocessor, and this microprocessor is connected with LCD display circuit, A/D change-over circuit, failure indicating circuit, output driving circuit, keyboard control circuit and signal input circuit respectively.
The intelligent high-pressure Direct Action Type isolating switch that the utility model provides is compared with existing contact knife formula swing arm isolating switch; Operating physical force is little, and compact conformation is small and exquisite, weight saving; Thereby make the switch cubicle volume-diminished, effectively detection of intelligent apparatus wherein, early warning and control circuit.
Description of drawings
Fig. 1 is the structural representation of the utility model intelligent high-pressure Direct Action Type isolating switch.
Embodiment
