The primary cut-out analog detection method of the application is illustrated with reference to Fig. 4.Fig. 4 is the primary cut-out of the application
The flow chart of analog detection method.As shown in figure 4, the primary cut-out analog detection method of the embodiment of the present invention can include with
Lower step.
Step S1, opens charge valve 7, and dielectric chamber 1 is vacuumized.
Step S2, in dielectric chamber 1 SF is filled with6Gas, works as SF6Gas reaches closing charge valve 7 after default pressure.

Moving contact 3 when closing a floodgate and during separating brake, the current signal and electromagnetic wave signal between static contact 2 and moving contact 3.
Current signal and electromagnetic wave signal between detection static contact 2 and moving contact 3, specifically, can detect static contact 2
With the current signal (i.e. breaker conjunction electric current) and electromagnetic wave signal of the "on" position between moving contact 3, and detection static contact 2
The current signal (i.e. breaker opens electric current) for opening a sluice gate state and electromagnetic wave signal between moving contact 3.By "on" position
Current signal and the current signal of the state of opening a sluice gate, can analyze the folding condition of breaker, and then assess the folding of breaker
Energy.Here, the application can simulate SF6Primary cut-out, to SF6The folding performance of primary cut-out carries out test assessment.
For example, by the current signal of detection "on" position, know electric current from the zero to stationary value institute Jing from current signal
Time, current amplitude fluctuation, the maximum of electric current etc., such that it is able to assess breaker, to reach the speed of conjunction, conjunction state stable
Property, conjunction state dynamic/static contact contact resistance size etc. close performance.In addition, the electromagnetic wave signal by detecting "on" position, can be with
The dynamic change situation of conjunction performance of the analysis breaker under alternating voltage.
Again for example, the current signal of state is opened a sluice gate by detection, knows electric current from stationary value to zero institute from current signal

In the high-tension circuit breaker analog device of the embodiment of the present invention, lid 11 can be opened, easily more be moved
Contact 3.During breaker is actually used, it is short-circuited in circuit, breaker experience short circuit current can unavoidably to dynamic
Contact causes ablation.In addition, breaker is opened a sluice gate and has electric arc to produce when closing a floodgate, the moving contact of meeting ablation breaker.Breaker makes
Longer with the time, moving contact ablation degree can be increasingly severe.There is ablation in moving contact, the contact resistance meeting between dynamic/static contact
Become big, cause breaker to generate heat, hydraulic performance decline during breaker closing.When moving contact ablation is serious, even if pulling insulated tension pole 5
To closing position, moving contact also will not be contacted with static contact, cause purpose of breaker failure.Therefore, the ablation degree of moving contact is disconnected
One of the deciding factor in road device life-span.The electromagnetic wave signal given off between dynamic/static contact when breaker is opened a sluice gate and closed a floodgate can be with
The ablation degree of reflection contact, when contact of breaker ablation is serious, the electromagnetic wave signal that it gives off can be distorted.At this
In inventive embodiments, moving contact of the moving contact 3 for difference ablation degree is changed, SF can be simulated6Primary cut-out is in different works
(SF under condition6The use time of primary cut-out is different, and the ablation degree of moving contact is different) folding performance.
In sum, the folding performance test of primary cut-out is carried out using above-mentioned high-tension circuit-breaker analogue means, it is excellent

Weight, makes test convenient；Second, it is not necessary to carry out field test again, can be tested at any time, saved the plenty of time into
This；3rd, the high-tension circuit breaker analog device of the application has substantially identical basic structure with actual breaker, can be complete
The main performance of equivalent breaker, has good booster action to work such as the Endurance Predictions of breaker.
In addition, by optimizing detailed design, can further improve the high-tension circuit breaker analog device of the embodiment of the present invention
Performance, including with the aspect such as the equivalence of actual breaker, security, reliability.Using three groups of identical primary cut-outs
Analogue means, three groups of high-tension circuit breaker analog devices are adopted three-phase circuit wiring and are powered with three phase mains, can also simulate three-phase
Some phenomenons under the actual condition of breaker.
Therefore, the agent structure of the high-tension circuit breaker analog device of the application and the structure base of actual high-voltage breaker
This is identical, to high-tension circuit breaker analog device applied voltage and when controlling its contact action, the phenomenon with actual breaker actuation
It is similar with property.Electric current and reality due to being mounted with current-limiting resistance in high-tension circuit breaker analog device, during breaker closing
Operating mode gap is larger, but reflects in the measurement results, and the proportional change of amplitude is showed only as when breaker feature is identical, can
The electric current or electromagnetism wave amplitude that obtain under actual measuring state are calculated to be directly opposite.In test process, first according to test needs
