Abstract
The invention discloses a switching device for a circuit breaker, which comprises a shell 1. The shell 1 is provided with a handle 2; the handle 2 is provided with a magnetic pole one 3; the shell 1 is provided with a magnetic pole two 4; and the magnetic pole two 4 is positioned at one end of the shell 1 in the same direction as the opening direction of the handle 2. The switching device has the advantages of low cost, simple realization of energy storage when the circuit breaker is opened, and normal and convenient return in the process of slowly opening.
Description
Technical field
The present invention relates to a kind of circuit breaker, particularly a kind of closing device of circuit breaker.
Background technology
In the slow separating brake process of the handle of general circuit breaker, situation not in place is usually arranged back, particularly in the automation control procedure, the result often causes product normally not close a floodgate.In multipole product,, make the complex manufacturing of product and require high because the handle answer is not in place; Product in use repeatedly uses to reach under hot conditions, and the back-moving spring characteristic of handle meeting variation handle occurs and replys situation not in place; Product owing to there is not the device of energy storage, makes the closing speed of handle relevant with people's operation in making process, and the performance of product is had certain influence, and existing technology employing stored energy mechanism complexity, the cost height.
Summary of the invention
At the defective of prior art, the invention provides a kind of closing device that is used for circuit breaker.
To achieve these goals, the technical solution used in the present invention is:
A kind of closing device that is used for circuit breaker comprises shell 1, and handle 2 is installed on the shell 1, and described handle 2 is provided with magnetic pole 1, and magnetic pole 24 on the shell 1, and magnetic pole 24 is positioned at an end of the identical shell 1 of handle 2 separating brake directions;
At least one is magnetic material for magnetic pole 1 under described and magnetic pole 24, and another is magnetic material or permeability magnetic material;
Described magnetic pole 1 and magnetic pole 24 are permanent magnet, iron-bearing materials or nickel-containing material.
Beneficial effect of the present invention: cost is low, realized the separating brake energy storage of circuit breaker simply, and in the process of slow separating brake, return is normal, makes things convenient for return.
Description of drawings
Fig. 1-Fig. 3, gate-dividing state schematic diagram of the present invention.
Embodiment
See also its implementation process of description of drawings: a kind of closing device that is used for circuit breaker, comprise shell 1, handle 2 is installed on the shell 1, described handle 2 is provided with magnetic pole 1, magnetic pole 24 on the shell 1, and magnetic pole 24 is positioned at an end of the identical shell 1 of handle 2 separating brake directions; At least one is magnetic material for magnetic pole 1 under described and magnetic pole 24, and another is magnetic material or permeability magnetic material; Described magnetic pole 1 and magnetic pole 24 are permanent magnet, iron-bearing materials or nickel-containing material.Magnetic pole 1, magnetic pole 24 must have one to be magnetic generally speaking, and another is magnetic or magnetic conductive material, and magnetic pole 1 can be done suitable adjustment with the gravitation size of magnetic pole 24 according to product requirement with distance of separation.During work, in the gravisphere of magnetic pole 1 and magnetic pole 24, force the handle answer to put in place by the gravitation that magnetic pole 1 and magnetic pole 24 produce, when the handle separating brake, under the effect of magnetic force, forced resetting.When handle closes a floodgate, in order to overcome magnetic force, staff uses certain strength to close a floodgate, and like this with regard to energy storage, has improved the closing speed of handle.Fig. 1 is the separating brake process to the motion process of Fig. 3, otherwise is making process.
Beneficial effect of the present invention: cost is low, realized simply the separating brake energy storage of breaker, and in the process of slow separating brake, return is normal, makes things convenient for return.
