Abstract
Description
Technical field
This novel practical belongs to the electrical engineering technical field, particularly a kind of impulse voltage generator that is used for gas-discharge tube, lightning protector etc. is carried out the impulse sparkover voltage test.
Background technology
Require the impact deboost of the surge protector of test signal and signal network among GB/T 18802.21-2004 " surge protector (the SPD)-performance requirement and the test method of low tension surge protector the 21st part telecommunications and signal network ", the GBT 18802.311-2007 " low pressure surge protection device the 311st part: gas-discharge tube (GDT) standard "; carrying out fast escalating rate impacts deboost and impacts resistance test; the waveform of impact generator is defined as open-circuit voltage 〉=1kV, and the rate of rise is 1kV/ μ s.Among the GA173-2002 " computer information system lightning protector " lightning protector is carried out impulse sparkover voltage when test, surge waveform is 1kV/ μ s.Among the TB/T 2311-2002 " railway electronic equipment lightning protector " lightning protector is carried out impulse sparkover voltage and lateral voltage test, surge waveform is 1kV/ μ s.Among the GB 9043-1999 " communication facilities overvoltage protection gas-discharge tube general technical specifications " gas-discharge tube is carried out impact flashover voltage when test; the nominal rate of rise of trial voltage is 1kV/ μ s; above standard all requires to adopt 1kV/ μ s surge voltage waveform to test; Related domestic documents does not propose the generation circuit of 1kV/ μ s, and Related product does not appear in market yet.Therefore we have designed and developed the desk-top 1kV/ μ s impulse voltage generator of a cover.It is little that it has a volume, and integrated intelligence degree advantages of higher is for the test of lightning protection component provides good test unit.
The utility model content
The purpose of this utility model is exactly the deficiency that exists at the above-mentioned background technology, and a kind of desk-top 1kV/ μ s impulse voltage generator is provided.
The technical solution of the utility model is: a kind of desk-top 1kV/ μ s impulse voltage generator, comprise single chip control module, dc high-voltage source module and major loop, single chip control module realizes controlled the connection with dc high-voltage source module and major loop respectively, and dc high-voltage source module and major loop are in series; Major loop is made up of on-off circuit parallel with one another and harmonic circuit, and on-off circuit is made up of main capacitor, high-pressure mercury switch and the resistance identical with the wave regulating resistor resistance institute of connecting successively, the harmonic circuit by wave regulating resistor and harmonic electric capacity in parallel form.
Have as preferred version of the present utility model:
1, is in series with the output build-out resistor on the described major loop.
2, described single chip control module comprises single-chip microcomputer Programmable Logic Controller, touch-screen type man machine operation interface and analog-to-digital conversion module.
3, described dc high-voltage source module adopts the I.F.T. rectification of boosting.
The utility model is in practice, single chip control module control dc high-voltage source module charges to major loop, after charged, the single step of releasing electrical testing is finished in the switch motion of control high-pressure mercury, realizes 1kV/us surge voltage waveform by accurate Waveform Design.
Single chip control module adopts mcu programming control, the precision maneuver of control high-pressure mercury switch, contactor etc., and man-machine interface adopts touch-screen to carry out visualized operation, and is simple to operate, the operation interface close friend.Analog-to-digital conversion module is measured demonstration in (voltage, electric current etc.) and is sent back in the single-chip microcomputer for screen displaying and protection action judgement (as overvoltage protection, overcurrent protection etc.); The whole control system is placed in the airtight can; shield effectiveness is good, and control system is reliable and stable.
DC high-voltage power supply adopts the I.F.T. rectification of boosting, and volume is little, and is in light weight, the highest exportable 10kV high direct voltage, and polarity of voltage can be transferred.
Major loop is made up of high-pressure mercury switch, main capacitor, harmonic inductance and wave regulating resistor, the high-pressure mercury switch has that speed is fast, volume is little and advantage such as noiseless, main capacitor adopts the high energy storage density impulse capacitor, its adopts metallized polypropylene film to make medium, the high voltage insulating materials sealing has that electrical property is good, good reliability, high temperature resistant, volume is little, capacity is big and good self-healing performance.
The open-circuit voltage rate of rise of the present utility model satisfies the wide-voltage range of 1kv/us, can test at 3500V and following gas-discharge tube or lightning protector sparking voltage.It is little to have volume, and integrated intelligence degree advantages of higher is for the test of lightning protection component provides good test unit.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment:
Single chip control module control dc high-voltage source module (2) charges for major loop (3), charged after, the single step of releasing electrical testing is finished in control high-pressure mercury switch (3.1) action, realizes 1kV/us surge voltage waveform by accurate Waveform Design.
Single chip control module adopts mcu programming control, the precision maneuver of control high-pressure mercury switch (3.1), contactor etc., and man-machine interface adopts touch-screen to carry out visualized operation, and is simple to operate, the operation interface close friend.Analog-to-digital conversion module is measured demonstration in (voltage, electric current etc.) and is sent back in the single-chip microcomputer for screen displaying and protection action judgement (as overvoltage protection, overcurrent protection etc.); The whole control system is placed in the airtight can; shield effectiveness is good, and control system is reliable and stable.
DC high-voltage power supply (2) adopts I.F.T. to carry out voltage boosting dc, and volume is little, and is in light weight, the highest exportable 10kV high direct voltage, and polarity of voltage can be regulated.
Major loop (3) is made up of high-pressure mercury switch (3.1), main capacitor (3.2), harmonic electric capacity (3.5) and wave regulating resistor (3.3), is serially connected with an output build-out resistor (3.4) on the major loop.The high-pressure mercury switch has that speed is fast, volume is little and advantage such as noiseless, main capacitor adopts the high energy storage density impulse capacitor, it adopts metallized polypropylene film to make medium, high voltage insulating materials sealing has that electrical property is good, a good reliability, high temperature resistant, volume is little, capacity is big and good self-healing performance.
The test findings (see figure 5) proves that the voltage rate of rise of the utility model output voltage can satisfy the requirement of standard in a big way, can test at 3500V and following gas-discharge tube or lightning protector sparking voltage.
