Abstract
The utility model relates to an over-travel adjusting mechanism for a breaker contact. The over-travel adjusting mechanism comprises an insulation casing, a vacuum arc-extinguishing chamber, an insulation pull bar, columns, a support plate and a permanent magnetic mechanism with a closing screw rod. The vacuum arc-extinguishing chamber is arranged in the insulation casing; the insulation pull bar is arranged at the upper end of the vacuum arc-extinguishing chamber; the columns are arranged over the insulation casing; the upper ends of the columns are equipped with the support plate; the permanent magnetic mechanism is fixedly connected over the support plate through screws; and an adjusting component is arranged between the lower end of the closing screw rod and the upper end of the insulation pull bar. The lower end of the closing screw rod is provided with a left helical thread, the upper end of the adjusting component is provided with a left helical inner thread correspondingly, the upper end of the insulation pull bar is provided with a right helical inner thread, and the lower end of the adjusting component is provided with a right helical outer thread correspondingly. According to the over-travel adjusting mechanism, an over-travel breaker is adjusted through the right-and-left threads on the adjusting component, the structure is simple, operation is convenient, the adjusting precision is high, and strong practicality is provided.
Description
Technical field
The utility model relates to a kind of contact of breaker, relates in particular to a kind of contact of breaker overtravel governor motion.
Background technology
Circuit breaker is a kind of electric safety device, for preventing breaker closing spring and keeping certain contact pressure in "on" position, overtravel adjustment structure is often set on the drive link of breaker operation mechanism.The overtravel structure of using is at present below supporting bracket, to be provided with spacer, regulates the height of supporting bracket by the spacer of taking, and this overtravel is measured apart from being inconvenient to, and precision is not high.
Summary of the invention
The utility model provides a kind of solution inconvenient operation, a kind of contact of breaker overtravel governor motion that precision is not high;
The technical scheme that the utility model addresses the above problem is:
A kind of contact of breaker overtravel governor motion, comprise insulated case, vacuum interrupter, insulated tension pole, pillar, supporting bracket and the permanent magnet mechanism of combined floodgate screw rod is installed, vacuum interrupter is arranged on insulated case inside, insulated tension pole is arranged on vacuum interrupter upper end, pillar is arranged on insulated case top, and pillar upper end is provided with supporting bracket, supporting bracket top is fixed with described permanent magnet mechanism by screw, between the lower end of combined floodgate screw rod and the upper end of insulated tension pole, is provided with regulating part.The lower end of combined floodgate screw rod has the screw thread of left-hand screw, and corresponding regulating part upper end has levogyrate inner thread with it, and the upper end of insulated tension pole has dextrorotation internal thread, and corresponding regulating part lower end has dextrorotation external screw thread with it.
On the basis of technique scheme, the utility model can also be done following improvement,
Further, described regulating part is hexagonal.
The beneficial effects of the utility model are:
The utility model reaches the object that regulates circuit breaker overtravel by the positive/negative thread on regulating part, regulating part adopts hexagonal, convenient adjusting, and the utility model is simple in structure, easy to operate, and degree of regulation is high, and has very strong practicality.
