Abstract
The utility model discloses a shell for the control and the protection of a switch. The shell for the control and the protection of the switch comprises a switch base, wherein the bottom of the switch base is provided with an air inlet, and the top of the switch base is provided with an air outlet. The beneficial effects of the shell for the control and the protection of the switch are mainly that the direction of the air outlet at the upper part of the base is downward so that no foreign matters enter a switch major loop and the heat radiation function of ventilation from up to down is provided.
Description
Technical field
The utility model relates to the housing that a kind of control and protective switch is used, and belongs to electric equipment technical field.
Background technology
Control and protective switch is a kind of intelligent device for switching that the functions such as circuit breaker, contactor, thermal relay are rolled into one.Be mainly used in the occasion that need to protect motor.The structure of this class switch on market mainly comprises following components: major loop contact terminal system, electromagnetism adhesive system, fault trip system, signal acquiring and processing system, auxiliary contact system.The radiating mode of control protection switch is in the market very unreasonable.Part producer is for the good heat dissipation effect of switch, allows the penetrating up and down of switch pedestal, and air-flow is entered by bottom, and flow out on top, takes away the heat that current-carrying part produces.But the shortcoming of doing is like this exactly foreign material easily enters switch inside by opening above, causes switch loose contact, even burning of contact.Also have part producer to enter switch for fear of foreign material, only in the bottom of base, open thermovent, will make like this air cannot free flow, switch internal temperature is too high, have influence on performance and the life-span of switch, and can when large electric current disjunction, make the air expanding rapidly not export smoothly and delay extinguishing of electric arc, finally reduce the breaking capacity of switch.
Utility model content
The purpose of this utility model is to solve in prior art controls the bad problem of housing radiating effect of using with protective circuit, and the housing that provides a kind of control and protective switch to use solves the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
The housing that control and protective switch is used, comprising: switch pedestal, and the bottom of described switch pedestal is provided with air inlet, and the top of switch pedestal is provided with gas outlet.
As preferred version, the direction of described gas outlet is downward.
As preferred version, also comprise contact guide rod, described contact guide rod is arranged on switch pedestal middle part.
As preferred version, on described contact guide rod, be socketed with moving contact.
As preferred version, described moving contact two ends are respectively equipped with fixed contact.
As preferred version, described fixed contact bottom is provided with arc-extinguish chamber.
The beneficial effects of the utility model are mainly reflected in: the direction of the gas outlet on base top is downward, so neither have foreign material and enter switch major loop inside, have taken into account again upper and lower penetrating radiating effect simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For making that architectural feature of the present utility model and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1, the housing that a kind of control and protective switch is used, comprising: switch pedestal 1, and the bottom of described switch pedestal 1 is provided with air inlet 7, and the top of switch pedestal 1 is provided with gas outlet 8.
As preferred version, the direction of described gas outlet 8 is downward.
As preferred version, also comprise contact guide rod 4, described contact guide rod 4 is arranged on switch pedestal 1 middle part.
As preferred version, on described contact guide rod 4, be socketed with moving contact 6.
As preferred version, described moving contact 6 two ends are respectively equipped with fixed contact 3.
As preferred version, described fixed contact 3 bottoms are provided with arc-extinguish chamber 2.
The beneficial effects of the utility model are mainly reflected in: the direction of the gas outlet on base top is downward, so neither have foreign material and enter switch major loop inside, have taken into account again upper and lower penetrating radiating effect simultaneously.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the shape described in the utility model claim scope, structure, feature and spirit change and modify, and all should be included within the scope of claim of the present utility model.
