Abstract
The utility model relates to a successive power supply and electricity-saving device used for lightening street lamp, switching null line and adjusting voltage. The device comprises a machine cabinet, a main power air switch, a Programmable Logic Controller, an adjusted voltage outputting contactor, a protecting circuit, an operating panel, a lightning-proof air switch, a lightning-proof device, an auto-transformer, a grounding array, a wiring terminal, a selective switch, an indicating lamp and an externally-touching test switch, all of which are integrated into and arranged inside the machine cabinet to form a whole. When in work, the current-day time of switching-on and switching-off is controlled by the Programmable Logic Controller. During the period of switching on the lamp, the voltage is adjusted within specified time by a consumer, so as to stabilize the voltage within a reasonable range, thus not only meeting the requirement of lightening but also prolonging the service life of the lamp and conserving the electricity energy. The output tap of the auto-transformer can adapt to various power supply voltage places.
