Description
Technical field
Patent of the present invention belongs to power electronics application, technical field of power systems, relates generally to detection apparatus for portable anti-parallel thyristor zero-cross trigger.
Background technology
Traditional detection method to anti-parallel thyristor zero-cross trigger is to make an anti-parallel thyristor zero-cross trigger detection platform, uses oscilloscope to show the zero cross fired waveform of moment simultaneously.This detection platform is because volume is big, weight is big, only be adapted at producing producer's use of anti-parallel thyristor zero-cross trigger, when the anti-parallel thyristor switch breaks down in the industry spot, can't failure judgement point whether at over-zero trigger, therefore can only carry out overall pulling down to over-zero trigger and change, cause very big waste, and workload be also very big.
No matter the detection apparatus for portable anti-parallel thyristor zero-cross trigger that the present invention introduces is in over-zero trigger manufacturer, or the industry of anti-parallel thyristor switch is used on-the-spot, can both directly detect over-zero trigger or switch, without any need for auxiliary equipment, replaced traditional detection platform, volume is little, and is in light weight, is easy to carry about with one.At present at home, do not see identical or similar techniques outward as yet.
Summary of the invention
Detection apparatus for portable anti-parallel thyristor zero-cross trigger of the present invention mainly is made up of fuse, anti-parallel thyristor module, capacitor, indicator light, zero passage comparison circuit etc., and working power is industrial frequency AC 220V, and electric current is 2.3A.
The basic principle of this device: working power is connected in the triggering line of anti-parallel thyristor zero-cross trigger, control command line and this device back that correctly links to each other.
After pressing " test " button, the control command signal is transferred on the anti-parallel thyristor zero-cross trigger, and over-zero trigger begins to send triggering signal after passing through zero balancing.
If the triggering signal of over-zero trigger can constantly correctly be sent in zero passage, the conducting of anti-parallel thyristor module, the capacitor energising do not have impulse current in a flash, then relay indicating light is lighted, and illustrates that over-zero trigger is working properly.
If over-zero trigger has fault, the zero cross fired signal can not send, and perhaps can not send when zero passage, and then relay indicating light does not work.
This device is equipped with current sensing means in capacitor loops, can detect the electric current of capacitor in real time.When the anti-parallel thyristor module is not to be triggered constantly in zero passage, have the impulse current that is higher than its load current value in a flash in the capacitor conducting.Checkout gear can send signal after detecting impulse current, disconnects indicator light work loop, indicator light is not lighted, thereby judged whether anti-parallel thyristor zero-cross trigger has fault.
The advantage of detection apparatus for portable anti-parallel thyristor zero-cross trigger of the present invention:
1, can carry, be convenient to detect in the industry spot of anti-parallel thyristor switch;
2, device itself has the zero passage comparison circuit, does not need to use oscilloscope when detecting, and reduces the quantity of using auxiliary equipment;
3, using on-the-spotly when anti-parallel thyristor zero-cross trigger or anti-parallel thyristor switch are detected, do not needing it is separated main equipment, only needing that line related is led to detection system and get final product.

Embodiment
Consult Fig. 1, electric once part of the present invention mainly contains: the major loop of being made up of fuse, anti-parallel thyristor module, capacitor; The show circuit of forming by indicator light, relay normally closed contact.
Consult Fig. 2, electric secondary of the present invention partly mainly contains: DC power supply TF1, the current sampling circuit of being made up of current transformer PTA1, capacitor C 1C2, diode D1D2, resistance R 1R2, amplifier U1; The comparison loop of forming by resistance R 3R4R6, amplifier U2; The reference voltage loop that resistance R 5, capacitor C 3, voltage-stabiliser tube DZ1 form; The signal output loop that resistance R 7, triode Q1, relay R LY1 form; Button S1 ,+control command signal output loop that the 12V DC power supply is formed.
Fig. 3 has provided application example of the present invention--the zero cross fired performance of-detection anti-parallel thyristor zero-cross trigger.Press wiring shown in the figure, output control command signal terminal out1 of the present invention, out2 link to each other with the sub-In1 of the command input end of anti-parallel thyristor zero-cross trigger, In2; Anti-parallel thyristor module triggering line G1 of the present invention, K1, G2, K2 link to each other with pulse output end G1, K1, G2, the K2 of anti-parallel thyristor zero-cross trigger.
During work, press Fig. 3 the present invention is correctly linked to each other with anti-parallel thyristor zero-cross trigger, and connect the AC220V working power.At this moment, the not conducting of anti-parallel thyristor module among the present invention, indicator light does not work.
Press the button S1, + 12V control command signal is sent to anti-parallel thyristor zero-cross trigger, anti-parallel thyristor zero-cross trigger sends trigger impulse to terminal G1 of the present invention, K1, G2, K2 constantly in zero passage, and the conducting of anti-parallel thyristor module has produced electric current in the primary circuit.
Among Fig. 2, current transformer PTA1 measures the electric current in the primary circuit, after amplifier U1 conversion, and output voltage signal.When the primary circuit electric current was rated value, output voltage signal was 2V.Voltage-stabiliser tube DZ1 connects with resistance R 5 in the reference voltage loop, exports constant reference voltage 2.2V.Amplifier U2 compares reference voltage and actual measurement primary circuit current value (being converted into voltage signal), and the output level of comparison loop is added on the resistance R 7.If capacitor is switched on constantly in zero passage, then can not produce impulse current, the practical measurement of current value is less than reference value, the comparison loop output low level, the last no-voltage of R7, not conducting of triode Q1, relay R LY1 is failure to actuate, indicator light is bright in the primary circuit, illustrates that anti-parallel thyristor zero-cross trigger is working properly.If capacitor is not switched on constantly in zero passage, then can produce impulse current, measured value is greater than reference value, comparison loop output high level, triode Q1 conducting, relay R LY1 action, indicator light does not work in the primary circuit, illustrates that anti-parallel thyristor zero-cross trigger work is undesired.
The present invention has been described according to preferred embodiment.Obviously, reading and understanding above-mentioned detailed description postscript and can make multiple correction and replacement.What this invention is intended to is that the present invention is built into all these corrections and the replacement that has comprised within the scope that falls into the appended claims or its equivalent.
