High Pressure Sodium Lamp works is activated when the light bulb, arc tube arcing between the
Enamelware at both ends, due to high temperature arc tube evaporation heat of sodium amalgam mercury vapor and sodium vapor into the cathode to the anode electric launch movement, the impact discharge atomic substances, to get excited ionization energy generation, and then by the excited state back to the stable state; or ionized into the excited state, and then return to base e infinite loop the excess energy to light radiation form of release, it had a light. High Pressure Sodium Lamp starts, in the initial phase of mercury vapor and xenon gas in low pressure discharge. At this time, light bulbs low voltage, current large; as discharge continues, the temperature gradually rising arc, mercury, sodium vapor pressure of the most cold-side temperature of the discharge is determined, when the discharge tube cold end temperature to stabilize, discharge will tend to be stable, light bulbs luminous flux, voltage, operating current and power is still in normal working condition. Under normal operating conditions, the whole boot process takes about 10 minutes.
General solution:
Between High Pressure Sodium Lamp in use because the voltage instability or disruption caused by off or restart the operating characteristics, uninterruptible power supply (UPS) in High Pressure Sodium Lamp of applications have been
Aluminum Casting adopted. However, the general dual transform UPS power mode, so although you can get high quality output power, but after a bipolar transformation efficiency has been greatly reduced, generally 80% to 90%, even the latest high-efficiency UPS also only 95%. To 100KVA of UPS, for example, generally about 90% of its efficiency, then the UPS's own loss of light reached 10K, will consume 10 kWh of electricity per hour, one day is 240 kWh, a year after their loss of light will be UPS a staggering 87,600 units of electricity. At the same time because the UPS inverter with a long set, UPS's own life is also greatly reduced. So use UPS to High Pressure Sodium Lamp to provide back-up power supply using the cost is very high. As China's rapid economic development, there has been a shortage of energy; began limitations in some areas and peak load shifting electricity use Cuoshi to Huanjie power shortage problem, the state Ye issued the call to establish saving society. In response to the country's call, while a significant reduction in use for the user cost, to solve the problem of low conversion efficiency UPS has become an urgent issue. Burke Corporation put in a lot of time and money developing a new type of fast switching emergency power supply (EPS).
Burke targeted EPS power solution:
Emergency Power Supply (EPS) is a Fire lighting using the back-up power, when properly used in the main power directly to the main electricity supply, the main exception to the battery inverter power supply. This does not need when the main power supply through the transformation, lighting the fire directly to the power supply, greatly improved efficiency. But the traditional EPS power supply switching time are generally long, can only be applied to ordinary lamps. Burke for High Pressure Sodium Lamp Company did a lot of switching test results showed that: High Pressure Sodium Lamp power interruption for more than 3.8mS if the above situation occurs off, lights need to re-start, during breaks 10 minutes of illumination. High pressure sodium lamps for special power requirements, Burke Power Equipment Company Ltd. precision designed and manufactured a new type of Chao fast switching EPS , in addition to High Pressure Sodium Lamp, but is also a wide range of
Coach Bags Shu halide lamps, mercury lamps and other requirements on the power switch time high lighting.
