DISTRIBUTING BOARD WITH FUNCTIONS OF PREVENTING INJURY FORM SALT AND AUTOMATIC CONTROLLING OF INNER TEMPERATURE

摘要

PURPOSE: A distribution board is provided to protect electric power facilities by installing a ventilation fan for internal air ventilation and a blast fan for external air exhaustion. CONSTITUTION: A blast fan(1) for external air exhaustion comprises a filter for preventing damage from sea wind. A ventilation fan(3) for internal air ventilation revolves in response to an output signal of inverters. A temperature detection sensor(5) detects temperature inside a distribution board and transfers it to a controller. A detection sensor for exhausted air amount is installed on a duct exit for air ventilation of the blast fan for external air exhaustion. A display unit(7) indicates state information of the temperature inside the distribution board, driving state of the blast fan, and the filter for preventing damage from sea wind.
