Embodiment
To be described in further detail the utility model embodiment below.
Double-standard locomotive AC-DC conversion switch of the present utility model, its preferably embodiment be:
Comprise four supporting insulators rotating insulator and be arranged in around described rotation insulator, described rotation insulator is provided with conducting copper, described supporting insulator is provided with contact flat spring, the contact flat spring on corresponding two supporting insulators of two ends difference of described conducting copper.
Described fixed contact pedestal is provided with shell fragment clamp system.
Described conducting copper is double layer copper bar, and described shell fragment clamp system is provided with two pairs of contact flat springs, and the end of every layer of copper bar is inserted between often pair of contact flat spring.
Described rotation insulator is connected with pneumatic or motor-operating mechanism.
Double-standard locomotive AC-DC conversion switch of the present utility model, by insulator support, double layer copper bar and contact flat spring, overcomes the defect that existing similar technique can not tolerate big current, ensures that contact is reliable and is convenient to safeguard.Compared with prior art had advantage and disadvantage is:
1, double-standard locomotive AC-DC conversion switch of the present utility model is by double-deck mounting structure, while improving main circuit current capacity, reduces the thickness of contact flat spring, ensures to enter fluent movements and contact reliable.
2, double-standard locomotive AC-DC conversion switch moving contact link of the present utility model cancels the flexible connection structure of like product, improves Reliability of Microprocessor and life-span.
3, double-standard locomotive AC-DC conversion switch structure of the present utility model is simple, and electric insulation is high, can bear the impact of severe haze weather condition, installing/dismounting and easy to adjust, is easy to carry out attended operation on roof.
4, double-standard locomotive AC-DC conversion switch ac output end of the present utility model and DC output end can exchange, and facilitate mounting arrangements on car.
Specific embodiment:
As shown in Fig. 1 a to Fig. 3 b, support fixed contact pedestal 3 respectively by four supporting insulators 1, the switching motion of main circuit is realized by being rotatably installed in the double layer copper bar 2 rotated on insulator 5 by the pneumatic operator of change over switch; After conversion puts in place, the two ends of double layer copper bar 2 enter the shell fragment clamp system be arranged on fixed contact pedestal 3 respectively, realize the conducting of opposite side circuit.
The operation principle of this specific embodiment is:
Turn DC side by AC: when double-standard locomotive AC-DC conversion switch is in AC state, drive double layer copper bar structure to enter DC side shell fragment clamp system from AC shell fragment clamp system by change over switch actuator.
Otherwise, proceed to AC by DC side.
Double-standard locomotive AC-DC conversion switch is not with arc-control device, does not have the ability of drop-out current; Therefore, its everything all must carry out in non-Electric region or when falling arciform state in pantograph.
The technical parameter that this specific embodiment provides comprises: rated operational voltage: 1.5kVdc/30kVac; Rated current: 2.6kAdc/1kAdc; Short-time withstand: 16/40kA (1s); Tolerance lightning impulse: 210kV; Power-frequency withstand voltage: 85kV.
Adopt the technical scheme that this embodiment provides, completed the conversion of main circuit by the driving mechanism of double-standard locomotive AC-DC conversion switch, thus achieve the conversion utilization under locomotive two kinds of standards.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
