Abstract

Low-current Townsend stage of negative corona discharge in air and conditions of its occurrence were studied. This stage can occur in the range of applied voltage lower than the voltage characteristic for Trichel pulse generation. Effect of various factors on the Townsend stage occurrence was studied. Experimental conditions facilitating observation and study of the Townsend stage were found. Current-voltage characteristic of the Townsend stage of the corona discharge was obtained, and photographs of the glow of this stage were taken. An explanation was proposed for the causes of occurrence or absence of the Townsend stage during ignition of a negative corona discharge.

  • negative corona
  • trichel pulses
  • dark Townsend discharge

Таунсендовская стадия отрицательного коронного разряда в воздухе атмосферного давления

Проведено исследование слаботочной таунсендовской стадии отрицательного коронного разряда в воздухе и условий ее возникновения. Эта стадия может возникать в области напряжений, меньших напряжений, характерных для генерации импульсов Тричела. Изучено влияние различных факторов на появление таунсендовской стадии. Найдены экспериментальные условия, облегчающие наблюдение и исследование таунсендовской стадии. Получена ВАХ таунсендовской стадии коронного разряда, сделаны фотографии свечения этой стадии. Предложено объяснение причин появления или отсутствия таунсендовской стадии при зажигании отрицательного коронного разряда.
