Abstract
The invention relates to a novel SF6 gas insulation high-voltage air reactor. The reactor comprises an SF6 insulation metal casing and two groups of cylinder type winding structures arranged in the casing. A plurality of capacitor rings are arranged on the outsides of the cylinder type winding structures, an insulation basin is arranged at one end of the metal casing, and a shielding layer is arranged on the surface of the inside of the metal casing. The air reactor is used under the condition that the voltage is larger than 50kV and the current is larger than 0.1A, SF6 gas insulation and SF6 gas and other gas mixed insulation media are used, magnetic permeable materials for leakage flux of the high-voltage air reactor are arranged in the SF6 insulation metal casing, leakage flux is prevented from diffracting onto the metal casing to generate eddy heating, and the temperature rising of the air reactor in a metal tank is reduced.
Description
Technical field
The present invention relates to a kind of reactor, relate in particular to a kind of New type of S F6 gas insulated high voltage air core reactor.
Background technology
Common reactor has series reactor and shunt reactor.Series reactor is mainly used to the high order harmonic component in limiting short-circuit current and filtering electrical network.Shunt reactor is used for absorbing the capacitive reactive power in electrical network, can carry out adjust operation voltage by adjusting the quantity of shunt reactor.Superhigh pressure shunt reactor is improved the several functions of the relevant operation conditions of Power System Reactive Power, mainly comprises: the 1) capacity effect on light zero load or underload circuit, to reduce Frequency Transient Overvoltage; 2) voltage improving on long distance transmission line distributes; 3) make reactive power in light hours circuit in-situ balancing as far as possible, preventing that reactive power is unreasonable flows, and has also alleviated the power loss on circuit simultaneously; 4) when unit and system are arranged side by side greatly, reduce power frequency steady state voltage on high voltage bus, be convenient to generator synchronous arranged side by side; 5) prevent the excitation resonance phenomena that generator band long transmission line may occur; 6) when adopting reactor neutral point to sell reactance grounded device, also available little reactance compensation circuit refers to and phase earth capacitance, to accelerate secondary arc current automatic distinguishing, is convenient to adopt single-phase high-speed reclosure; 7), for the larger load test product of the capacity current test product of test loop.
Summary of the invention
The present invention provides a kind of simple in structure, New type of S F6 gas insulated high voltage air core reactor of using safety, working stability in order to overcome the above problems.
Technical scheme of the present invention is: described reactor comprises SF6 insulated metal shell and is arranged on two groups of drum type brake winding constructions in metal shell, described drum type brake winding construction outside is provided with a plurality of electric capacity rings, metal shell one end is provided with insulating basin, and described inside of metal outershell surface is provided with screen.
Before and after two groups of described drum type brake winding constructions, be connected in series, described drum type brake winding construction is formed by stranded conductor layering coiling, is provided with a glued membrane compound inslation between adjacent two layers wire.
Described electric capacity ring surface coating semiconductor layer.
Described screen is magnetic layer.
The present invention is a kind ofly greater than 50kV for voltage, electric current is greater than under 0.1A condition, adopt the high-pressure hollow reactor of SF6 gas-insulated and SF6 gas and other gas mix insulation media, the permeability magnetic material that high-pressure hollow reactor leakage field is used is housed in SF6 insulated metal housing, preventing that leakage field is diffracted into produces eddy-current heating on metal shell, reduce the temperature rise of air core reactor in metal can.
