Abstract
The utility model discloses an intelligent protection switch for a power distribution box, which comprises a casing. A control panel and a magnetic saturation circuit breaker are installed inside the casing; the control panel is formed by a sampling circuit, a single chip microcomputer and a relay; and the sampling circuit is connected to the single chip microcomputer which is connected to the relay, and the relay is connected to the magnetic saturation circuit breaker. The technical scheme of the intelligent protection switch includes that when an electric power line breaks down, the switch can automatically turn off, and when the breakdown of the electric power line is cleared, the switch can automatically reset to restore electricity to users promptly, thereby bringing convenience to the electricity utilization for users.
Description
Technical field
The utility model relates to a kind of intelligent protection switch, relates in particular to a kind of intelligent protection switch that is used on the distribution box.
Background technology
Along with power load constantly increases; Electrical Safety becomes current social question of common concern; present protection switch is when the electricity consumption excess load; automatically outage; when but feeder line fault is eliminated; but nobody splits to close and carries out reset operation again, so that the delay that restores electricity, and brings very big inconvenience to user power utilization.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can be when power circuit breaks down, switch is disconnected, again can be when feeder line fault be eliminated, distribution box intelligent protection switch that switch is resetted.
In order to solve the problems of the technologies described above; the utility model provides a kind of distribution box intelligent protection switch; this protection switch comprises a housing; a control board and a magnetic saturation circuit breaker are installed in this housing; described control board is made up of sample circuit, single-chip microcomputer and relay; described sample circuit is connected with single-chip microcomputer, and this single-chip microcomputer is connected with relay, and described relay is connected with the magnetic saturation circuit breaker.
Further, also connect a buzzer siren on the described control board.
The beneficial effects of the utility model are:
1, technical solutions of the utility model can be when power circuit breaks down, the switch automatic disconnection, and when feeder line fault was eliminated, switch automatically reset, and in time for the user restores electricity, has made things convenient for user power utilization.
2, technical solutions of the utility model are simple in structure, and cost is low, and are applied widely.
Description of drawings
Below in conjunction with the drawings and specific embodiments technical solutions of the utility model are described in further detail.
Fig. 1 is the circuit principle structure schematic diagram of the utility model intelligent protection switch.
Embodiment
As shown in Figure 1; the utility model intelligent protection switch has a housing; a control board and a magnetic saturation circuit breaker are installed in this housing; described control board is made up of sample circuit, single-chip microcomputer and relay; described sample circuit is connected with single-chip microcomputer; this single-chip microcomputer is connected with relay, and described relay is connected with interior dropout in the magnetic saturation circuit breaker, also connects a buzzer siren on the described control board.
Operation principle of the present utility model is as described below: sample circuit takes signal to send to single-chip microcomputer from power circuit, judge whether it is the fault signal behind the single-chip microcomputer acknowledge(ment) signal, if fault-signal, single-chip microcomputer sends cut-off signals to relay, interior dropout in the relay control magnetic saturation circuit breaker is thrown off, thereby protection switch is disconnected; If normal signal, single-chip microcomputer sends reset signal to relay, the interior drop-away reset in the relay control magnetic saturation circuit breaker, thus protection switch is resetted.When breaking down, single-chip microcomputer sends a signal to buzzer siren, alarm work.
The utility model is not limited to the described scope of the foregoing description, and every technology distortion of being done according to the technical solutions of the utility model principle all falls within the protection range of the present utility model.
