Description
Technical field
The present invention relates to a kind of chopper spring test device and method of testing thereof, be used for testing chopper divide, closing rebound characteristic, belong to high-voltage switch gear technical field of measurement and test.
Background technology
Current industry is use dividing of mechanical property instrument test chopper, closing rebound characteristic, the presence or absence of spring can only be measured, but the amplitude of spring can not be shown, the position of frequency and spring, thus there occurs that bounce is difficult to analyzing dividing of the generation that comes into question, closing time point, and lookup reason, improve the hands section of circuit breaker electric performance, national standard does not allow separating brake to have the phenomenon of spring, but it is frequently encountered by separating brake spring in the fabrication process, but the size of spring can not be shown, the parameters such as process, great difficulty is caused for problem analysis and searching solution.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of can test out chopper point, conjunction process occurs chopper spring test device and the method for testing thereof of all waveforms of spring, solve use mechanical property instrument test chopper point, closing rebound characteristic, it is impossible to the amplitude of display spring, frequency and spring the problem of position.
In order to solve above-mentioned technical problem, the technical scheme is that and provide a kind of chopper spring test device, it is characterized in that, including power supply, power supply connects by connecting the resistance of wire and 2 series connection, the two ends of an one resistance chopper in parallel, the two ends of this resistance are an oscillograph in parallel also.
Preferably, 2 described resistance are equivalent pure resistance.
Preferably, described oscillograph is digital oscilloscope.
Preferably, described oscillographic transverse axis is time coordinate, and the oscillographic longitudinal axis is test signal amplitude coordinate.
A kind of method of testing of chopper spring test device, it is characterized in that, after described breaker open operation, on oscillograph, the signal of display is the terminal voltage of the resistance in parallel with chopper, the spring waveform produced in separating brake process, the size of amplitude fluctuates at the resistance terminal voltage in parallel with chopper; After breaker closing, the voltage signal on oscillograph is shorted, the size of the spring waveforms amplitude that making process produces is to fluctuate at the resistance terminal voltage in parallel with chopper, whole spring process can be recorded on oscillograph by dividing or closing of every time operating, do not have the spring waveform of wave chopping that chopper is correspondingly improved by analyzing, until chopper divides or closes a floodgate without spring waveform.
By the invention enables chopper point, conjunction process can test out all waveforms that spring occurs, concrete time point, the order of severity of spring and amplitude, frequency and the spring process that can show that bounces occurs, to check that whether breaker operator is stable, the improvement for product provides foundation.
The invention have the advantage that
1, spring waveform intuitive display, point, making process spring all waveforms can both show, it does not have cut-off wave situation.
2, the credible event of contact of breaker contact can be found from the size of waveforms amplitude and frequency.
3, the timing node of spring to point or the Time Calculation closed go out to bounce and occur in the position of contact.
4, chopper drive gap can be adjusted correspondingly and improve from the number of times of spring, frequency and amplitude size.

Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The present invention is a kind of chopper spring test device, as it is shown in figure 1, it is by chopper, two 70 �� equivalence pure resistances, oscillograph, 12v DC source and 2.5mm2Connect the compositions such as wire.
DC source connects by connecting the pure resistance of wire and 2 series connection, and the two ends of a resistance R2 chopper in parallel, the two ends of this resistance R2 are a digital oscilloscope in parallel also.
DC source is available to oscilloscope signal source, and resistance R1 is equipment protection resistance, resistance R2 divides for chopper, conjunction process provides the signal of spring change, oscillograph to oscillograph be chopper is divided, the be hit by a bullet signal recording of saltus step of conjunction process stores.
Chopper according to the schematic diagram of Fig. 1 by each element 2mm2Soft copper wire connect, chopper point, combined floodgate manual operation. Oscillographic transverse axis is time coordinate, and the longitudinal axis is test signal amplitude coordinate. After breaker open operation, on oscillograph, the signal of display is the terminal voltage of resistance R2, as in figure 2 it is shown, the spring waveform produced in separating brake process, the size of amplitude fluctuates in resistance R2 terminal voltage. After breaker closing, the voltage signal on oscillograph is shorted, as it is shown on figure 3, the size of the spring waveforms amplitude of making process generation is also fluctuate in resistance R2 terminal voltage. Whole spring process can be recorded on oscillograph by dividing or closing of each operation, does not have the spring waveform of wave chopping that chopper is correspondingly improved by analyzing, and divides until chopper or closes a floodgate without the waveform that bounces, as shown in Figure 4.
