Through the utility model discloses make the circuit breaker minute, close the in -process and can test out all wave forms that take place the spring, can demonstrate the concrete time point that the spring takes place, the order of severity of spring is amplitude, frequency and spring process to whether inspection circuit breaker operation is stable, provides the basis for the improvement of product.
Description
Technical field
This utility model relates to a kind of chopper spring test device, be used for testing chopper divide, closing rebound special
Property, belong to high-voltage switch gear technical field of measurement and test.
Background technology
At present industry is use mechanical property instrument test chopper point, closing rebound characteristic, bullet can only be measured
The presence or absence jumped, but the position of the amplitude of spring, frequency and spring can not be shown, thus there occurs spring
Phenomenon be difficult to analyze come into question occur point, closing time point, and search reason, improve circuit breaker electric performance
Means, national standard does not allow separating brake to have the phenomenon of spring, but is frequently encountered by separating brake bullet in the fabrication process
Jump, but the parameters such as the size of spring, process can not be shown, problem analysis and searching solution are caused
Great difficulty.
Summary of the invention
The technical problems to be solved in the utility model is: provide one can test out chopper point, closed
Journey occurs the chopper spring test device of all waveforms of spring, solves use mechanical property instrument test disconnected
Road device point, closing rebound characteristic, it is impossible to the problem of position of amplitude, frequency and the spring of display spring.
In order to solve above-mentioned technical problem, the technical solution of the utility model there is provided a kind of chopper spring and surveys
Electricity testing device, it is characterised in that include power supply, power supply connects by connecting the resistance of wire and 2 series connection, and one
The two ends of an individual resistance chopper in parallel, the two ends of this resistance oscillograph also in parallel.
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.
Make chopper can test out, during dividing, closing, all ripples occurring to bounce by this utility model
Shape, it is possible to demonstrate concrete time point, the order of severity i.e. amplitude of spring, the frequency of spring generation and bounced
Journey, to check that breaker operator is the most stable, the improvement for product provides foundation.
The utility model has the advantages that:
1, spring waveform intuitive display, point, making process spring all waveforms can show do not have
There is cut-off wave situation.
2, can find, from size and the frequency of waveforms amplitude, the credible event that contact of breaker contacts.
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 by number of times, frequency and amplitude size from spring
And improvement.

Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
This utility model is a kind of chopper spring test device, as it is shown in figure 1, its by chopper, two
70 Ω equivalence pure resistances, oscillograph, 12v DC source and 2.5m m2Connect 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 are in parallel
One chopper, the two ends of this resistance R2 digital oscilloscope also in parallel.
DC source is available to oscilloscope signal source, and resistance R1 is equipment protection resistance, and resistance R2 is disconnected
Road device divides, close during provide the signal of spring change, oscillograph to oscillograph be chopper is divided, conjunction process
Be hit by a bullet saltus step signal recording store.
Chopper according to the schematic diagram of Fig. 1 by each element 2m m2Soft copper wire connect, chopper point,
Combined floodgate manual operation.Oscillographic transverse axis is time coordinate, and the longitudinal axis is test signal amplitude coordinate.Chopper
After separating brake, on oscillograph, the signal of display is the terminal voltage of resistance R2, as in figure 2 it is shown, produce during separating brake
Spring waveform, the size of amplitude fluctuates in resistance R2 terminal voltage.After breaker closing on oscillograph
Voltage signal is shorted, as it is shown on figure 3, the size of the spring waveforms amplitude of making process generation is also at resistance
R2 terminal voltage fluctuates.Whole spring process can be recorded on oscillograph by dividing or closing of every time operating,
Chopper is correspondingly improved by the spring waveform not had wave chopping by analysis, until chopper divides or closes a floodgate without bullet
Jump waveform, as shown in Figure 4.
