Detailed Description
Various embodiments of the present utility model are disclosed in the following drawings, which are presented in sufficient detail to provide a thorough understanding of the present utility model. However, it should be understood that these physical details should not be used to limit the utility model. That is, in some embodiments of the present utility model, these physical details are not necessary. Moreover, for the sake of simplicity of illustration, some well-known and conventional structures and components are shown in the drawings in a simplified schematic manner.
In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present utility model.
Referring to fig. 1-4, the conventional circuit breaker has a structure that a handle is designed in the middle of a space, the space on two sides of the handle is completely wasted, and other components can only be distributed to two sides outside the space of 45mm, so that the volume of a finished product of the circuit breaker is increased. Based on this, the application provides a compact electromagnetic opening and closing circuit breaker, comprising a circuit breaker body;
the specific breaker body comprises a shell 1, wherein a cavity 11 is arranged on the inner side of the shell 1, and the cavity 11 is larger than or equal to 45mm;
further, a front baffle 2 is arranged on the outer side of the housing 1 for closing a cavity 11 arranged in the housing 1.
In this embodiment, all operating mechanisms 4, electromagnetic switching-on and switching-off mechanisms 6, electromagnets 5, overload protection trippers, instantaneous, short-circuit protection trippers, contact systems and arcing systems of the circuit breaker and all circuit breaker components of the arc extinguishing chamber are all designed in a 45mm space. The operation structure is compact, the occupied space is small, more space is saved for other parts, and the layout is reasonable.
The operating mechanism 4 and the electromagnetic opening and closing mechanism 6 are arranged on the inner side of the cavity 11, and an operating handle of the operating mechanism 4 extends upwards to the outer side of the shell 1.
An electromagnet 5 is arranged above the electromagnetic opening and closing mechanism 6, and an arc extinguishing mechanism 7 is arranged below the electromagnetic opening and closing mechanism.
The handle of the operating mechanism 4 is biased to the left.
A fixed distance is kept between the electromagnetic opening and closing mechanism 6 and the electromagnet 5.
One or more through holes are arranged at the outer side frame of the shell 1 and are connected with the front baffle 2 through positioning pieces 3.
In the embodiment, because the positions and the structural design of the handle and the operating mechanism 4 are reasonable and compact, the electric opening and closing electromagnet 5 and the overload and short-circuit protection electromagnetic mechanism can be sequentially designed on the right side of a space of 45mm, and because the operating direction is just perpendicular to the operating mechanism 4, the optimal stress and the shortest stroke design direction are adopted for opening, closing and tripping of the driving operating mechanism 4;
compared with the prior art that the circuit breaker cannot design the shortest distance product in the vertical direction, the circuit breaker also needs to be added with intermediate conversion parts, so that the parts are increased, the cost is increased, the transmission space is increased, and the miniaturization of the miniature circuit breaker is deviated;
meanwhile, a contact system, an arc striking system and an arc extinguishing chamber are designed below a space of 45 mm. The magnetic increasing sheets are arranged above and below the contact and inside the fixed contact, and the design is favorable for the accelerated movement of the electric arc. When short-circuit current passes through the circuit breaker, the contacts are opened, electric arcs are generated among the contacts, and the electric arcs rapidly move into an arc striking system under the action of a magnetic field and finally enter into an arc extinguishing grid plate;
based on the above-mentioned setting, can arrange all circuit breaker mechanical structure in 45mm space inside, this design needs sampling current transformer, leakage transformer, PCB etc. that increase to intelligent circuit breaker to save great space, can do to increase in traditional circuit breaker's space has functions such as electric leakage, intelligent monitoring, intelligent protection, need not lengthen and widen volume and occupation, has absolute advantage in the old project of changing of electric circuit, can accomplish 1 to 1 replacement.
The foregoing description is only illustrative of the utility model and is not to be construed as limiting the utility model. Various modifications and variations of the present utility model will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, or the like, which is within the spirit and principle of the present utility model, should be included in the scope of the claims of the present utility model.
