Abstract
An arc generation device working on basis of a parallel resonance mode comprises a parallel resonance circuit composed of a capacitor (1) and an inductor (2), the basis resonance of the parallel resonance circuit is in a power frequency voltage, an isolation knife switch (4) is embedded into and connected to the resonance circuit (6) in series, the voltage of the resonance circuit (6) is provided by output of a high leakage impedance transformer (3), and input of the resonance circuit (6) is a power supply system. By means of the arc generation device working on basis of the parallel resonance mode, small power supply power passes indoors, so that current needed by arcs passes through the isolation knife switch, and power formed by voltage between the added current and a fracture enables the whole arc generation device to achieve stable arc striking when the isolation knife switch (4) is disconnected.
Description
Technical field
The present invention relates to a kind of arc generating device, especially relate to a kind of arc generating device based on the work of parallel resonance mode.
Background technology
Isolation switch is the most frequently used connecting and disconnecting of the circuit opertaing device of transmission line of electricity, limited in one's ability due to its breaking current, and sometimes because maloperation is used to breaking current, the accident that result causes can destroy the equipment cabinet of place system.For avoiding the generation of accident, just need the generation of cold plasma and this cold plasma makes the form of insulation breakdown, process is done and systematically studied.For this reason, just a kind of can stablizing is needed to produce electric arc and do not affect the pilot demonstration device of other consumer.
Summary of the invention
Technical matters to be solved by this invention, be just to provide a kind ofly to be powered by small-power power, can the arc generating device based on the work of parallel resonance mode of repeatable operation.
Solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of arc generating device based on the work of parallel resonance mode, it is characterized in that: comprise a shunt-resonant circuit be made up of electric capacity 1 and inductance 2, and its fundamental resonance is under power-frequency voltage, one isolation switch 4 embeds and is serially connected in this resonant tank 6, the voltage of described resonant tank 6 is provided by the output of a high-leakage impedance transformer 3, resonant tank 6 be input as electric power system.
Described high-leakage impedance transformer 3 be input as 0.4kV.
So, the resonance current value flowing through disconnecting link 4 is then determined by the capacitor value of the voltage on resonant tank divided by electric capacity.
When disconnecting link 4 breaking course, disconnecting link 4 edge of a knife starts to produce electric arc, when the edge of a knife pulls open to a certain extent, may occur arc extinction; Now, the leakage reactance of high-leakage impedance transformer 3 and resonant inductance 1 induction reactance limit the electric current 5 that electric power system flows into jointly.
Effect of the present invention is: very little 0.4kV low pressure and low power input, a larger resonance power can be produced on a 10kV system and device, when excising this resonance power, the power that electric capacity 1 and inductance 2 store all is used to edge of a knife electric arc and heats surrounding air, makes arcing maintain a period of time; The edge of a knife whether blow-out, depends on that the leakage reactance of high-leakage impedance transformer 3 is to the restriction of electric current flowing into native system.
Accompanying drawing explanation
Fig. 1 is operating diagram of the present invention.
Embodiment
Below in conjunction with drawings and the specific embodiments to the present invention is described in further detail.
Based on an arc generating device for the 10kV electrical voltage system isolation switch of parallel resonance mode work, comprise main resonance electric current in parallel 6, disconnecting link 4 formed by primary resonant capacitor 1 and main resonance reactance 2 and be embedded into and be connected in series in main resonance loop; Exciter transformer 3 controls the operating voltage of resonant tank, resonant tank 6 be input as electric power system, and provide the loss in the middle of main resonance loop; The electric current 5 that wherein exciter transformer 3 flows out when normal only accounts for about 3% of main resonance electric current 6.When this structure makes disconnecting link flow through the energy of 60kvar, excitatory change only provides the power input of 2kVA.
When disconnecting link action, in inductance 2 and electric capacity 1, institute Chu energy causes edge of a knife arcing, be equivalent to be joined by arc resistance in main resonance loop, electric power system starts to main resonance loop makeup energy to meet the energy loss of arc glow, heating, with pilot arc and main resonance state.
The leakage reactance of exciter transformer 3 is by the energy supply of restriction to main resonance loop.When increment is less than heating and luminous energy ezpenditure, electric arc is by automatic distinguishing.Electric power system becomes powers to by excitatory change 3 leakage reactance and main resonance reactance 2 series loop, supply size of current to determine primarily of excitatory change 3 leakage reactance.In the present embodiment after disconnecting link 4 arc extinguishing, the electric current that 0.4kV power supply provides is 50A, is approximately 10kVA, is only 1/6 of electric capacity 1 energy storage, still within the acceptable range.
