Description
Technical field
The utility model relates to a kind of proving installation, particularly a kind of proving installation that is used for the measurement of plastic case breaker over-travel synchronism.
Background technology
The excess of stroke also is over travel, and term is used for the power equipment isolating switch more, after the excess of stroke is the complete closure of contacts of vacuum switch, and the moving or mobile distance of static contact.The effect of the excess of stroke mainly contain following some: a) guarantee that contact still can keep certain contact pressure after electrical wear; B) can utilize touch spring power buffering during contact closure, reduce spring; C) when the contact separating brake, make moving contact obtain certain initial kinetic energy, break the melting welding point, improve initial opening velocity, reduce the arc time, thereby improve the speed of medium recovery.The method of testing of the excess of stroke is to adopt vernier caliper by measuring mutually at present, owing to there is not unified positioning fixture, therefore be difficult to guarantee test point be positioned at the contact directly over, be difficult to also guarantee that the three-phase test point is on same horizontal line, therefore need a kind of contact over travel synchronism proving installation of exploitation, to solve the problems of the technologies described above.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of contact over travel synchronism proving installation, this device can guarantee test point be positioned at the contact directly over, can guarantee that again the three-phase test point on same horizontal line, has solved the problem of measuring the excess of stroke and synchronism simultaneously simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is:
Contact over travel synchronism proving installation, comprise a base plate and two back up pads that are provided with relatively, on two back up pads guide rail is installed, slide block is installed on the guide rail, form the space of ccontaining contact between base plate, two back up pads and the guide rail, slide block is provided with the through hole that inserts for pit gauge; On the base plate of described back up pad one side biside plate is installed relatively, biside plate is provided with at least one group of spacing hole, and gag lever post is installed in the spacing hole.
As the utility model improvement of the technical scheme, described guide rail is provided with two, has certain slit between two guide rails, and the through hole on the described slide block is relative with this slit.
The beneficial effects of the utility model are: when adopting the utility model test contact excess of stroke, pit gauge places in the through hole of slide block, and tested contact places under the guide rail, and sliding slider moves pit gauge can test the out of phase excess of stroke; Tested contact is closed a floodgate, pit gauge places directly over the contact, then with the pit gauge zero clearing, close a floodgate again after then removing static contact, mobile pit gauge is to the contact, the numerical value that pit gauge shows is excess of stroke value, gag lever post can guarantee pit gauge be positioned at the contact directly over, the method for testing of synchronism is that opening apart from subtracting each other of three-phase promptly obtained the three-phase synchronism.In sum, adopt the utility model can guarantee test point be positioned at the contact directly over, can guarantee that again the three-phase test point on same horizontal line, has solved the problem of measuring the excess of stroke and synchronism simultaneously simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic perspective view of the present utility model.
Embodiment
With reference to Fig. 1, the disclosed contact over travel synchronism of the utility model proving installation, comprise a base plate 1 and two back up pads 2 that are provided with relatively, on two back up pads 2 guide rail 3 is installed, slide block 4 is installed on the guide rail 3, form the space of ccontaining contact between base plate 1, two back up pads 2 and the guide rail 3, slide block 4 is provided with the through hole 5 that inserts for pit gauge.
As shown in the figure, on the base plate 1 of back up pad 2 one sides, biside plate 6 is installed relatively, biside plate 6 is provided with three groups of spacing holes 7, wherein in one group of spacing hole 7 gag lever post 8 is installed, by this gag lever post can guarantee pit gauge be positioned at the contact directly over, and can test the contact of different size model by the gag lever post that is installed in not in the spacing hole on the same group.
As shown in the figure, the guide rail 3 that the utility model adopts has two, has certain slit between two guide rails 3, and the through hole on the slide block is relative with this slit, and the pit gauge of the measuring contacts excess of stroke can insert from the slit between through hole on the slide block and two guide rails.
Method of testing of the present utility model is such: pit gauge places in the through hole of slide block, and tested contact places under the guide rail, and sliding slider moves pit gauge can test the out of phase excess of stroke; Tested contact is closed a floodgate, pit gauge places directly over the contact, then with the pit gauge zero clearing, close a floodgate again after then removing static contact, mobile pit gauge is to the contact, the numerical value that pit gauge shows is excess of stroke value, gag lever post can guarantee pit gauge be positioned at the contact directly over, the method for testing of synchronism is that opening apart from subtracting each other of three-phase promptly obtained the three-phase synchronism.In sum, adopt the utility model can guarantee test point be positioned at the contact directly over, can guarantee that again the three-phase test point on same horizontal line, has solved the problem of measuring the excess of stroke and synchronism simultaneously simultaneously.
Certainly; the utility model is not limited to above-mentioned embodiment; the utility model also can have other structural change; quantity as spacing hole also can be provided with or the like according to the specification of tested contact; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
