Description
Technical field
The utility model relates to Control protection field of switches, specifically, is related specifically to a kind of reversible Control protection device for switching.
Background technology
Control and protective switch is from its 26S Proteasome Structure and Function, and control and protective switch series of products are no longer contactor or the single product such as circuit breaker or thermal relay, but a set of Control protection system.Its appearance fundamentally solves traditional employing discrete component, and owing to selecting unreasonable, control and protection that is that cause coordinates irrational variety of problems; particularly overcome due to adopt combine between the electric equipment products of different appraisal standards time; protective feature coordinates inharmonic phenomenon with control characteristic, drastically increases the operational reliability of Control and protection system and continuous runnability.
The defect of existing control and protective switch is:
Traditional control and protective switch all lacks radiator structure, and therefore the radiating effect of its horizontal direction and vertical direction is poor, and the heat radiation of its general effect is limited.
Utility model content
The purpose of this utility model is for deficiency of the prior art, provides a kind of emery wheel checkout gear, to solve the problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Reversible Control protection device for switching, comprises substrate; First control and protective switch, the second control and protective switch, short-circuit alarming contact, overload-alarm contact and power module are installed on the substrate; One end of described first control and protective switch is connected with short-circuit alarming contact, and its other end is connected with power module; One end of described second control and protective switch is connected with overload-alarm contact, and its other end is connected with power module; Offer the air channel laterally run through in the lower end of substrate, offer radiator structure on the surface of substrate, described radiator structure comprises louvre, heat-conducting piece and via hole; Described louvre is uniformly distributed along the flow direction in air channel and is set to one group between two, and between two louvres often organized, be provided with heat-conducting piece, the two ends of described heat-conducting piece connect the louvre of the left and right sides respectively, are connected with via hole in the inner side of heat-conducting piece.
Further, the inside of described substrate also has thermal hole, and one end of described thermal hole is positioned at the below of the first control and protective switch and the second control and protective switch, and the other end of thermal hole is connected with air channel.
Further, the edge of described substrate has the draw-in groove for installing radiating fin, and the inwall of draw-in groove extends internally formation spacing preiection, and the outer end of spacing preiection stretches out formation bayonet socket.
Compared with prior art, the beneficial effects of the utility model are as follows:
Structure is simple, and design ingenious, by arranging radiator structure on housing, the free convection taking full advantage of horizontal direction and vertical direction is dispelled the heat, good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of reversible Control protection device for switching described in the utility model.
Number in the figure illustrates: substrate 1, first control and protective switch 2, second control and protective switch 3, short-circuit alarming contact 4, overload-alarm contact 5, power module 6, air channel 7, louvre 8, heat-conducting piece 9, via hole 10, draw-in groove 11.
