Abstract
Disclosed in the utility model is a heat dissipating high-voltage directly operated type isolating switch comprising a substrate, a housing, a circuit board, a frame and a heat dissipation device, wherein the circuit board, the frame and the heat dissipation device are arranged on the substrate. The circuit board is connected with the frame; and a shield is arranged outside 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, the utilization of the heat dissipation device enables the service life of the switch to be effectively prolonged and the failure occurrence to be effectively reduced.
Description
Technical field
The utility model relates to the heat radiating type high voltage isolator 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, designs a kind of miniaturization heat radiating type high pressure Direct Action Type isolating switch.
The technical scheme of the utility model is, a kind of heat radiating type high pressure Direct Action Type isolating switch comprises pedestal, shell, and the wiring board on the pedestal, pedestal and heat abstractor, 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; 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 heat abstractor comprises aluminium base and the aluminum thermal fin that is fixed in aluminium base; Said aluminum thermal fin comprises a plurality of radiating fins, and said radiating fin surface is provided with nickel coating, is provided with the tin layer between said radiating fin and the aluminium base, and said radiating fin and aluminium base weld together through the tin layer.The heat abstractor that the utility model provides can effectively prolong the physical life and minimizing fault of switch.
