The utility model content

The technical problem that the utility model will solve is for overcoming weak point of the prior art; Provide a kind of can be low excessively to the power factor that occurs in the electrical network, harmonic wave, three-phase imbalance and because of voltage waveform takes place that voltage fluctuation and flickering problem that distortion causes are regulated, filtering and elimination, can in time not handle the quality of power supply device for automatically regulating of the band remote controllers of emergency at the scene yet.

For solving the technical problem of the utility model; The technical scheme that is adopted is: a kind of quality of power supply device for automatically regulating with remote controllers; Comprise remote controllers, magnetic valve type reactor, the telemetry circuit that is connected with the magnetic valve type reactor, harmonic branch road, capacitor compensation assembly, balance of voltage adjusting parts; Magnetic valve type reactor and harmonic branch road, capacitor compensation assembly, the balance of voltage are regulated parts and are connected in parallel; Remote controllers are made up of Audio Controller, relay switch, lead, loud speaker, recorder; Loud speaker, recorder place Audio Controller inner; Through lead Audio Controller, relay switch, loud speaker, recorder are linked to each other; The magnetic valve type reactor is the DC excitation controllable transducer, and the coil of magnetic valve type reactor is made up of reactance coil and magnet exciting coil, and reactance coil and harmonic branch road are connected in parallel; Magnet exciting coil is electrically connected with the output of controlled dc excitation power; The harmonic branch road is the harmonic passage, is connected to form by capacitor, inductor, resistor in series, and the capacitor compensation assembly is made up of the above capacitor compensation parts of two covers that are connected in parallel; The capacitor compensation parts are made up of the 3rd circuit breaker, first filter reactor, the first switching parts, the first capacitor group that connects that be in series; Balance of voltage adjusting parts are made up of the 4th circuit breaker, second filter reactor, the second switching parts, the second capacitor group that connects that be in series, and the output of telemetry circuit is electrically connected with the control end of controlled dc excitation power, the first switching parts, the second switching parts respectively, are used for the variation according to detected electric network reactive-load trend, the size of power factor, the content of harmonic wave and the degree of balance of voltage and come to control respectively the size of magnet exciting coil DC excitation electric current, the switching of capacitor compensation parts and the switching that the balance of voltage is regulated parts.

Beneficial effect with respect to prior art is, solved the power quality problem that occurs in the electrical network, greatly improved the quality of electric energy, and is rational in infrastructure, practical, also can in time not handle emergency at the scene, easy to use, reduced cost.
