Abstract
The utility model relates to an alarm circuit, in particular to a motor alarm circuit which can realize timely alarm and comprises a motor electrically connected with a power supply, wherein the motor is connected in parallel with three groups of filter circuits U1 by three binding posts, and at least one group of control circuits in three groups of filter circuits U1 are connected in parallel with an alarm circuit U2. Pulse can be formed when surge on the circuit changes obviously, therefore, energy can be easily consumed. The motor alarm circuit can timely eliminate surge, thus reducing energy consumption; and simultaneously, the circuit is added in a junction box, therefore, power factor can be automatically adjusted to an optimal state at any time, and pollution of circuits and electrical appliances caused by long-time use can be eliminated, so that electron sequence turbulence can be restored gradually, and further the service life of the motor can be prolonged.
Description
Technical field
The utility model relates to a kind of warning circuit, is specifically related to a kind of motor warning circuit that can realize timely warning.
Background technology
At present, terminal box all is installed on motor, what insert in the terminal box generally all is to connect electric circuit normally, but, in the process of our use, mains supply is often unstable, make it greatly formation pulse of surge variation on the circuit, and consumed lot of energy, and in addition, the span of motor power (output) and the diligent coupling accurately that is difficult to of the reality of machinery, therefore, the power factor of most of motors does not reach, and the big minor matter of more doing work some machine work the time constantly changes, so and motor be conversion at any time can't reach best state.
Summary of the invention
The utility model provides a kind of rational in infrastructure at the deficiencies in the prior art, and is easy to operate, can prolong the motor motor warning circuit in useful life.
The technical solution of the utility model is achieved in that and comprises the motor that is electrically connected with power supply, described motor is parallel with three groups of filter circuit U1 by three binding posts, and has at least one group of control circuit to be parallel with warning circuit U2 among three groups of filter circuit U1.
Described filter circuit U1 is made up of diode D1, resistance R 1, resistance R 2, light-emitting diode D2, capacitor C 1, triode Q1, wherein diode D1 be divided into three tunnel, one routing capacitance C1 ground connection after resistance R 1 is connected; Another road is electrically connected with triode Q1, and triode Q1 base stage is through resistance R 2 ground connection, and triode Q1 emitter is through light-emitting diode D2 ground connection; Third Road is electrically connected with warning circuit U2.
Described warning circuit U2 is made up of triode Q2, light-emitting diode D3, D4, D5, D6, D7, resistance R 3, R4, R5, R6, thermistor R7, wherein the base stage of triode Q2 is by in parallel light-emitting diode D4, D5, D6, D7, thermistor R7 ground connection, and diode D4, D5, D6, D7 are in series with R3, R4, R5, R6 respectively; The emitter of triode Q2 is by light-emitting diode D3 ground connection.
The utlity model has following good effect: the surge on the circuit changes and forms pulse very big the time, so easy consumed energy, the utility model can be eliminated surge timely, thereby reduced the consumption of energy, add this circuit in the terminal box the inside simultaneously, can automatically power factor be adjusted to optimum state at any time, repair in circuit, the electrical equipment because of using the pollution that causes for a long time, the E-serial disorder is progressively repaired, prolong electrical machinery life.
