Title: A backup power supply system having a null transfer time
Inventor: FENG YA-TSUNG
IPC: H02J9/06
Filed: 2003-10-24
Abstract: An apparatus related to a backup power supply system having a null transfer time is presented. When the first AC power source is normal, the first AC power source supplies power to the load. And the second AC power source supplies power to the load with a null transfer time while the first AC power source fails. The DC/AC power converter generates the second AC power source. The output current of the DC/AC power converter is controlled to approach to null when the first AC power source is normal. Then, the output mechanical switch of the DC/AC power converter can close and no circulating current flows between the first AC power source and the DC/AC power converter when the first AC power source is normal. The output mechanical switch keeps closed regardless of the first AC power source, so the backup power supply system performs the transferring function with null transfer time.

As such, water liquid is supplied from lower water supply pipe of the water supply piping and discharged in a mist manner in transverse direction through the water-driving covers above the upper water supply pipe to effectively remove smoke and flying dust. Meanwhile, the movable needle pins are driven upward by the water flow thereby preventing the central bores of the water spraying tubes from accumulation an attachment of blockage, such as scale and moss. In addition, the movable needle pin automatically moves downward to remove contamination and debris when water supply is cut off. When water is supplied through the upper water supply pipe, water liquid entering the water guide aperture of each water spraying tube performs strong reversal washing to the water spraying tube to ensure no blockage thereof.
