The utility model discloses can accomplish the detection requirement about product contact synchronism of GB10963, GB16916, GB16917.
Description
Technical field
The utility model relates to a kind of contact of breaker surveying instrument lock in time.
Background technology
Synchronous and the automatically jumping Performance Detection requirement to the contact of multipole circuit breaker in GB10963, GB16916, GB16917, its requirement is as follows:
1. the moving contact of all poles of multipole circuit breaker mechanically should connect like this; namely except neutral pole to be opened/closed (if any); no matter all pole is that manual operation or automatic operation are connected and disjunction simultaneously substantially simultaneously, even if be also like this when only there is overload a protection pole.The opening and closing neutral pole of four-pole circuit breaker should not close extremely afterwards than protection and first disconnect.Carry out inspection and Manual test by adopting suitable device (such as pilot lamp, oscillograph etc.) to check and whether meet the requirements.
If a pole 2. with suitable short circuit making breaking capacity is used as neutral pole, and isolating switch then all pole that is irrelevant manual operation comprise neutral pole can action simultaneously substantially.
3. isolating switch should have free tripping mechanism.
Contact at present for isolating switch synchronously detects, and market there is no the specialized equipment being exclusively used in and carrying out detecting by standard-required, and enterprise and laboratory still adopt oscillograph or special millisecond meter to coordinate miscellaneous equipment to detect, and complex operation, is unfavorable for detection efficiency.
Utility model content
In order to solve Problems existing in background technology, the utility model provides a kind of contact of breaker synchro measure detector automatically, and this detector detection speed is fast, and easy and simple to handle, detection efficiency is high.
For achieving the above object, the utility model adopts following technical scheme:
A kind of miniature circuit breaker contact synchro measure detector, comprise dropout power supply, direct supply, resistance, data acquisition unit, industrial control computer and display, it is characterized in that: the isolating switch as test product is circuit breaker multiple levels, this isolating switch has multipair contact, moving contact in often pair of contact connects with the positive pole of direct supply, static contact in often pair of contact is connected with the negative pole of direct supply by resistance, after static contact in often pair of contact and moving contact touch and close, direct supply and resistance form many loops, dropout power supply is connected with static contact respectively with the moving contact of in many loops, the positive pole of direct supply is connected with data acquisition unit, the static contact of often pair of contact is also connected with data acquisition unit, data acquisition unit is connected with industrial control computer, industrial control computer is connected with display.
The beneficial effects of the utility model are:
1, equipment can complete GB10963, GB16916, GB16917 testing requirement about product contact synchronism;
2, equipment possesses 500A dropout power supply, not only can complete unloaded lower product synchronism and detect, also can be used for product under overload, judge synchronism and automatically jumping Function detection.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the structure principle chart of the utility model detector;
Embodiment
Illustrate below in conjunction with accompanying drawing and with embodiment, the utility model to be further described:
Embodiment 1
As shown in Figure 1, a kind of miniature circuit breaker contact synchro measure detector, comprise dropout power supply, direct supply, resistance, data acquisition unit, industrial control computer and display, isolating switch as test product is circuit breaker multiple levels, 4 pole isolating switchs in the present embodiment, there are four pairs of contacts, moving contact in often pair of contact connects with the positive pole of direct supply, static contact in often pair of contact is connected with the negative pole of direct supply by resistance, after smart contact thus in often pair of contact and moving contact touch and close, direct supply and resistance form four loops, be respectively the first loop 1, second servo loop 2, tertiary circuit 3 and the 4th loop 4.Dropout power supply is connected with static contact respectively with the moving contact in the first loop 1, the positive pole of direct supply is connected with data acquisition unit, the static contact of often pair of contact is connected with data acquisition unit, and data acquisition unit is connected with industrial control computer, and industrial control computer is connected with display.
Wherein direct supply specification is+9V, and dropout power supply is AC power, and specification is≤4V, 500A, and data acquisition unit is NIUSB6009 collector.
The course of work of this detector is: closed by the killer switch as test product, at this time four loops, tunnel keep connecting, data acquisition unit collects each loop current signal, then manual cut-off breaker is carried out, four loop, tunnels disconnect, and data acquisition unit collects priority and the mistiming of not homopolarity disconnection; Then dropout power supply is opened, because dropout power supply causes overload, the dynamic/static contact in the first loop is threaded off, and then cause the dynamic/static contact in its excess-three bar loop to thread off, data acquisition unit collects sequencing and the mistiming of four loop open circuit, the data that industrial control computer collects according to data acquisition unit, are judged the synchronism of four pole contacts, and are shown by display.
It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
