Technical field
The utility model relates to control and protective switch, specifically, is related specifically to a kind of basic model control and protective switching device.
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:
Basic model control and protective switching device, comprises housing, short-circuit alarming contact, overload-alarm contact and release; Described short-circuit alarming contact is installed on one end of housing, overload-alarm contact is installed on the other end of housing, the inside of housing is provided with release, the gear selecting switch for regulating release precision is installed on the surface of described housing, one tunnel of the input of described release is connected with short-circuit alarming contact, and another road of the input of release is connected with overload-alarm contact; Offer the air channel laterally run through in the upper end of described housing, offer radiator structure on the surface of housing, 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, heat-conducting piece is provided with between two louvres often organized, via hole is connected with in the inner side of heat-conducting piece, the draw-in groove for installing radiating fin is had in the edge of housing, the bottom of draw-in groove has the heat transfer hole be connected with heat-conducting piece, the inwall of draw-in groove extends internally formation spacing preiection, and the outer end of spacing preiection stretches out formation bayonet socket.
Further, described housing is also provided with thermal hole, and one end of thermal hole connects the inside of housing, and the other end of thermal hole connects air channel.
Further, the side of described housing is provided with auxiliary inserted block, and described auxiliary inserted block is connected and fixed by splicing ear and housing.
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
