Description
Technical field
The present invention relates to electric system protection device technical field of measurement and test, more particularly to using real time data display pair
The method of testing of arc light protecting device.
Background technology
Under normal circumstances gas is in state of insulation, once there are arcing events, gas will become electric conductor.Work as gas
Body atom is acted on by extraneous big energy, when making electronics be possible to depart from its nuclear constraint and become free electron, gas
Body is in powered state, and this process is called the ionization of gas.The electric arc formed during gas ionization, its voltage and current is according to electricity
Material composition different in source impedance, the spacing of electric conductor and environment and have huge difference.
It is circuit components damage, insulation breakdown, operation mistake, circuit overvoltage, short in the daily production of power system
The phenomenons such as road failure can all produce electric arc, and electric arc is provided simultaneously with the electric arc effect such as pressure, heat, light, sound and galvanomagnetic-effect.
The harm that switch cubicle arc short-circuit failure is produced is mainly manifested in the injury to field personnel and switchgear
And the infringement aspect of neighbouring controller switching equipment.Muscle, the nerve of induced voltage meeting infringer；The high-temperature gas meeting that arc burning is produced
The skin serious burn of people, strong flash of light meeting pierce eyes is set to cause the sound of Blackout, explosion to cause people
Tympanum, internal organs are damaged, the respiratory system of the toxic gas meeting harm people produced by arc burning；The energy of fault electric arc release makes
In switch cubicle air heat and expand, copper bar gasification so that the hurried rising of pressure in cabinet, produced burst pressure causes to switch
The deformation of cabinet disk body is even crushed；The plosive that arc burning is produced will also result in interior of equipment cabinet sharp pounding and cause element pine
It is de-.Additionally, arc fault is also possible to involve station straight-flow system, so as to cause huge economic loss.
The bus of current relaying configuration scheme, 35kV and following electric pressure does not typically install bus protection, works as generation
Processing mode is cut off using the back-up protection for carrying larger time delay mostly during failure, its movement time often beyond 1 second, this meeting
The serious scaling loss of causing trouble point device.Extinguish electric arc to quickly cut off failure, while being reflected in the electric arc of arclight and electric current

Analog quantity voltage exports the optical signal being directly proportional to input voltage as input), the device can enter with real time data display
Row connection, when emulation power system primary network breaks down, real time data display exports an analog quantity voltage (should
Arc light intensity during the real-time faults of voltage, the relation of the correlation behavior amount in arc light intensity and electrical network, by these shapes
State amount is through calculating.) light signal strength that arc light generating meanss are exported is controlled, during failure is carried out, arc
The intensity of optical signal changes with the change of related electric amount in electrical network.Using the method for testing proposed in the present invention to arc light
Protection device is tested, and more really simulates the running environment at arc light protecting device scene, can greatly improve arc light guarantor
Protection unit scene put into operation after operational reliability.
