Abstract
The utility model provides an overload wireless alarming device of an electric motor. The overload wireless alarming device consists of a power supply circuit, a current detective control circuit and a pre-alarm circuit, wherein the current detective control circuit is divided into two paths, one path is connected with the switch of the electric motor, and the other path is connected with the pre-alarm circuit; the pre-alarm circuit is connected with a wireless transmitter; and a reset button is arranged on the pre-alarm circuit. The overload wireless alarming device has the advantages of simple structure, good convenience and rapidness, safe and reliable operation, high working efficiency and the like.
Description
Technical field
The utility model relates to a kind of motor radio alarming device.
Background technology
Existing motor overload protection device only is to sense motor overload and the power supply that cuts off motor; if motor is temporary transient for a certain reason slight overload when operate as normal; existing motor overload protection device also can cut off motor power, so not only influences daily production but also can work the mischief to motor.
Summary of the invention
The purpose of this utility model provides a kind of electromotor overload radio alarming device, avoids the deficiencies in the prior art.
For achieving the above object, the utility model is taked following design:
Electromotor overload radio alarming device, by power circuit, current detection control circuit, warning circuit is formed, and current detection control circuit divides two-way, and one the tunnel links to each other with motor switch, one the tunnel links to each other with warning circuit, and warning circuit is connected with wireless launcher, and reset button is on warning circuit.
The utility model has the advantages that:
1, send radio alarming when the sensor-based system of motor overload protection device is sensed electric current near overload, the prompting staff notes, and motor is not out of service.
2, under the alarm condition, return to report to the police when normal as current of electric and stop automatically.
3, after the motor overload protection device was reported to the police, when continuing to rise as electric current, this device then can cut off motor power immediately within a certain period of time, to guarantee the safety of motor.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a circuit board schematic diagram of the present utility model.
Wherein: 1 power circuit, 2 current detection control circuits, 3 motor switches, 4 reset button, 5 warning circuits.
Embodiment
Electromotor overload radio alarming device, by power circuit 1, current detection control circuit 2, warning circuit 5 is formed, 2 fens two-way of current detection control circuit, the one tunnel links to each other with motor switch 3, and one the tunnel links to each other with warning circuit 5, warning circuit 5 is connected with wireless launcher, and reset button 4 is on warning circuit 5.
Voltage that current transformer L1, L2 induce through diode D2, D3 rectification, capacitor C 3 filtering after, the one tunnel through W1, R2 current limliting, if when surpassing the puncture voltage of DW2, the DW2 conducting, triode BG1 conducting, at this moment, IC sends wireless alarm signal in the air.The wireless receiver (existing product) that is installed in night shift room promptly sends warning.
Another road is through W2, R3 current limliting, if when exceeding the puncture voltage of DW3, and the DW3 conducting, triode BG2 conducting, at this moment, and the relay J adhesive, the contact J-1 of J disconnects, thereby makes motor out of service, reaches protective effect.
Form power circuit 4 by capacitor C 1, C2, resistance R 1, diode DW1, D1 in the circuit; Current transformer L1, L2, diode D2, D3, DW2, DW3, capacitor C 3, resistance W1, W2, R2, R3, triode BG1, BG2 form two-way current detection control circuit 5; The two ends of the normally-closed contact J-1 of relay J are connected to the Motor Control loop.
