Abstract
The utility model relates to an electronic protector for motors with a miniature air circuit breaker. The utility model integrates the functions of a switch and short circuit protection, so the utility model effectively solves the problem of imperfect protective functions for an electronic protector, and the complication of mounting main switches is eliminated at the same time, so that the utility model has the advantages of convenient installation and operation.
Description
Technical field
The utility model relates to a kind of electric motor control protector
Background technology
In the past as the small air circuit breaker of motor protection; hard-wired separately often; this is on record; such layout has promptly increased shared volume and has increased difficulty again; and because the increasing of wiring position, certainly will increase again the installation failure rate for this reason the utility model the problems referred to above are improved.Particularly relatively rational especially with the group box of small air circuit breaker and electric motor electron protector; also remedied the shortcoming of the short-circuit protection deficiency of electronic protector; current electric motor electron protector is quick on the draw, moves fast because of it; particularly in overload, overvoltage, the phase failure, electric leakage, in the protection its advantage that has and being extensive use of.But it is not good that its shortcoming is exactly a short-circuit protection function, even reaction also is insecure sooner because it as cutting-off of short-circuit electric current be contactor and by reaction time of tentaculum and arc extinguishing ability far away from air circuit.
Summary of the invention
The utility model is to realize like this.The box body device that does not contain contactor that it is made up of the Electronic Protection circuit; which is provided with button; the knob of delaying time brilliant this pipe of luminous indication, control loop insurance, current of electric setting knob, start-up time; it is characterized in that it also is provided with a small air circuit breaker; it can be fixedly installed on the outside that this box inboard or fixed card are connected on box, and its setting should be convenient to installation, operation and attractive in appearance.When being arranged in the box, it should place the upper of box, and the inlet wire binding post of its upper end should expose, and preferably flushes with the upper surface of box, and it is very attractive in appearance again so promptly to be convenient to connect electric power incoming line.Can be connected to the upper side of this box body as this as equally having when placing the outside of box, or be arranged on that upper side is taken back partially or one jiao.The side of small air circuit breaker flushes institute's vacancy part and is filled by the box body of protector with the side of the box body of protector, its combination should seem one and help attractive in appearance.Below no matter which kind of is provided with on the top input terminal that the form electric power incoming line all should be connected on the small air circuit breaker; its outlet terminal then is connected on the input terminal of protector, and the outlet terminal of protector then connects the upper connecting terminal of A.C. contactor and its lower connecting terminal connects motor.
Description of drawings
Fig. 1 contains the electric electromechanics protector that small air opens circuit.
Fig. 2 is a kind of internal circuit diagram of embodiment.
Embodiment
Among Fig. 11---contain the shell of small air circuit breaker electric motor protector; 2---the air circuit operating grip; 3---luminous indicating diode; 4---start stop button, KM---A.C. contactor and coil, M---motor; wherein the also available earth leakage circuit breaker of small air circuit breaker replaces; used circuit breaker one pole width is the product below 20mm, and 3 utmost points of composition or the small air circuit breaker of 4 utmost points are as CN45 series.Know for the body that reduces box body, button preferably uses pocket buttons or sensitive switch, and it is very simple that wiring is installed from this motor controlling protector as can be seen.
