What is the voltage stabilizer:
Voltage stabilizer is a device in electrical engineering designed to automatically maintain a constant voltage. A regulator may be of a simple “feedforward” design or may contain a negative feedback control loop. Servo motor control or relay control for the regulator. According to different design, voltage regulator can be divided into DC voltage and AC voltage. Regulators are often used in power supply systems to work with rectifiers, electronic filter, etc. to provide a stable output voltage, such as that required by microprocessors and other components. In large generators at alternator and even at power plants, regulators control the stability of the output voltage. In a distributed distribution system, regulators may be installed in a sub-station or along a wire extension to ensure a stable voltage regardless of the user’s power level. As some electrical appliances contain coil components, eddy currents will be generated at the beginning of electrification, which will weaken the instantaneous voltage at the start of the appliance, resulting in slow start-up and increase the instantaneous voltage after the circuit is broken, could cause a spark that could damage the circuit. At this point need a regulator to protect the normal operation of the circuit. The regulator is composed of voltage regulating circuit, control circuit and Servo Motor. When the input voltage or load changes, the control circuit samples, compares and magnifies, then drives the servo motor to rotate, so that the position of the carbon brush of the regulator changes, the output voltage is kept stable by automatically adjusting the turn ratio of the coil. The voltage regulator with large capacity also works on the principle of voltage compensation.
Why we need to use the voltage stabilizer:
With the rapid development of society, the use of electricity equipment is increasing day by day. However, the aging and lagging development of power transmission and distribution facilities, as well as poor design and insufficient power supply, result in low terminal user voltage and high terminal user voltage, on the electrical equipment, especially on the voltage requirements of high-tech and precision equipment, unique as a time bomb. As a public power grid, the municipal power system is connected with thousands of loads of various kinds, some of which are quite sensible, capacitive, switching power supply and so on, not only get power from the power grid, but also affect the power grid itself, the quality of power supply of power grid or local power grid is deteriorated, resulting in voltage waveform distortion or frequency shift. In addition, unexpected natural and man-made accidents, such as earthquakes, lightning strikes, power transmission and distribution systems open or short-circuit, will endanger the normal supply of electricity, thus affecting the normal work of the load. Unstable voltage will cause fatal injury or misoperation of equipment, affect production, lead to delay in delivery, unstable quality and other losses. At the same time, it speeds up the aging of the equipment, affects the service life and even burns down the fittings, which causes the owners to face the perplexity that needs to be repaired or to renew the equipment in a short time and wastes the resources.
Voltage regulator can be widely used in:
Industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, posts and telecommunications, hotels, scientific research and other departments of the computer, precision machine tools, computed tomography photography (CT) , precision instruments, test devices, elevator lighting, import equipment and production lines and other places that need power to stabilize the voltage. The utility model is also suitable for the users at the end of the low-voltage distribution network where the power supply voltage is too low or too high and the fluctuation range is large, and for the power equipment with large load variation. High-power compensated power regulator can be connected with fire power, hydraulic power, small generators.
