1. Why can lighting energy-saving equipment save electricity? The 21st century is an era of energy shortage. The electricity bill has become a veritable “electric tigerâ€, and 20%-35% of the current electricity bill is wasted! One of the reasons: in the power supply system, in order to avoid the power transmission process The line loss and the terminal voltage caused by the peak of power consumption are often transmitted at a higher voltage, exceeding the rated voltage of the powered device, and eventually the operating temperature of the device is increased and the energy consumption is increased. The second reason is that the user's power load is unevenly distributed on the three phases, which causes the reactive power loss to increase, and the reactive power of the power supply enterprise is increased. The third reason: the power line has a large amount of inductive load, and the system power factor is low, which causes the line loss to increase. The fourth reason: due to the internal and external environment, there are high harmonics in the system, which makes the operating equipment overheat, the energy consumption increases, and the meter is over metered. 2. What is the lighting regulator power saving cabinet? The GGDZ lighting regulator power-saving cabinet developed by Shanghai Panden Company is a new-generation lighting power-saving product composed of six technical units, such as compensation transformer, voltage regulating transformer, voltage regulating control mechanism, main circuit, control circuit and time control circuit. . The product is based on intelligent voltage regulation, three-phase full-range adjustment, and infinitely slow voltage regulation. According to the actual situation of power grid peaks and valleys, the stable voltage required for lighting fixtures can be output at any time; it has the functions of improving power factor and filtering harmonics and lightning surges. The power quality of the lighting power supply system is optimized twice, so as to achieve the dual purpose of extending the service life of the lamp and saving energy. 3. Why should the lighting use a voltage-saving power cabinet? When designing the street lamp power supply line, in order to avoid the line loss during the power transmission process and the terminal voltage is too low when the power supply peak is too low, the street lamp cannot be lit. The street lamp transformer determines that the output voltage is generally higher than the rated value by more than 5%. The fluctuations of the time, high and low, especially when the power is low at midnight, the grid voltage will be higher, the output voltage of the street lamp transformer will exceed 15% of the normal voltage, up to 255V. The voltage regulation function of GGDZ lighting regulator power-saving cabinet will always output stable voltage automatically. After the compensation transformer and voltage regulating transformer work, the output voltage can be optimized. The lamps used in street lamps are generally gas discharge lamps. Their optimal working voltage is 210V-200V. It only needs a higher working voltage at startup. After lighting, the output voltage is appropriately reduced and stabilized, which saves electricity and ensures brightness. And extend the life of the lamp. 4, GGDZ lighting regulator power-saving cabinet function and characteristics According to the use of street lighting, the product is designed to 230V-220V starting voltage, through 10 minutes of lamp preheating, so that the lamps start normally. According to the needs of road lighting, it automatically adjusts to the optimal working voltage of 210V-200V (user can set the output voltage arbitrarily); in the middle of the night, according to the needs of road lighting, the power supply voltage is automatically adjusted to produce a higher power saving effect. The product is stepless, stable, and slowly regulated. The voltage is 5V-20V per minute, and no impact voltage is generated on the lamp. The end lamp will not flash or go out. It can extend the service life of the lamp by more than 2 times, greatly reducing the maintenance cost of the lighting system, and the power saving rate is more than 25%, which saves electricity and saves energy. GGDZ lighting regulator power saving cabinet with automatic and manual bypass function will not affect the lighting when switching, and the equipment is easy to maintain. 5, GGDZ lighting regulator power saving cabinet and transformer, voltage regulator Different transformer is a voltage device that turns a voltage into another fixed voltage, there is no voltage regulation function. The regulator only outputs a standard voltage based on fluctuations in the grid. GGDZ lighting regulator power-saving cabinet has the dual functions of voltage transformation and voltage regulation. Through the control circuit and time control circuit, the lighting load is continuously analyzed to realize the optimal intelligent control. 6. Selection, installation and operation of GGDZ lighting regulator power-saving cabinet 1. According to the capacity of street lamp transformer, choose the same capacity GGDZ lighting regulator power-saving cabinet; 2. According to the actual power of the lighting load × 1.1, match the same capacity GGDZ lighting regulator power saving cabinet; 3. Connect the street light transformer output line to the power line terminal of the power saving cabinet; the output terminal of the power saving cabinet is connected with the lighting load, and the air switch is closed (the control section is set at the factory) Electricity, see the instruction manual for details, the power saving cabinet works normally. 4. When the power grid changes or the power saving cabinet fails, the equipment automatically bypasses the operation or automatically cuts off the power. At this time, an alarm signal is issued to notify the maintenance.
