Single Channel Voltage Regulator To Prevent The Generator Voltage Is Too Low And Lead To Electrical Equipment Work Disorders
The basic principle of Single Channel Voltage Regulator regulation
When the generator speed changes, to keep the voltage constant, only the corresponding magnetic pole to change the magnetic flux, that is, when n increases the sound to keep the voltage to maintain a certain. The size of the magnetic flux depends on the magnetic field current, so the speed changes as long as the automatic adjustment of the magnetic field current can keep the voltage to a certain. The Single Channel Voltage Regulator is based on this principle for voltage regulation.
The Single Channel Voltage Regulator is a single-stage contact type Single Channel Voltage Regulator with an arc-extinguishing system that effectively overcomes the shortcomings of ordinary single-stage contact-type Single Channel Voltage Regulator contacts that are prone to rapid ablation of the spark and is suitable for any 12V, 300W ~ 500W within the grid alternator.
The Single Channel Voltage Regulator adds a VD & mdash; L, C contact arcing system consisting of a diode VD, a choke coil L2 and a capacitor C, based on a conventional single-stage contact Single Channel Voltage Regulator.
When the generator voltage reaches the specified value, the magnetizing coil L1 turns on the contact, so that the adjustment resistor R2 and the acceleration resistor R1 are stepped into the magnetic field circuit so that the magnetic field current drastically decreases, resulting in a high self-inductance electromotive force , The induced current through the diode VD, choke coil L: constitute a loop, play a role in the continued flow to protect the contacts. In addition, at both ends of the contact through the L2 parallel capacitor, used to absorb the self-inductance electromotive force also reduces the contact spark.
The advantages of the single-stage contact type Single Channel Voltage Regulator having an arc extinguishing system are that only a pair of contacts are easy to adjust; not only the T contact spark is reduced, the contact life is prolonged and the radio interference is reduced; When the contact is opened, the self-induced current passes through the demagnetization of L2, thus accelerating the closure of the contacts and increasing the vibration frequency of the contacts
Overview of Single Channel Voltage Regulators
The Single Channel Voltage Regulator is the adjustment device that controls the voltage output from the generator within the specified range. Its function is to automatically control the generator voltage when the generator speed and the load of the generator are changed so as to keep the generator voltage constant and prevent the generator voltage from being High and burn out the electrical equipment and lead to excessive battery charging, but also to prevent the generator voltage is too low and lead to electrical equipment and battery failure.
