25-52 CIRCUITE BASCULANTE ASTABILE REALIZATE PE AUTOMATUL PROGRAMABIL PS-3 KLÖCKNER- MOELLER – Partea I-a

BISTABLE TRIGGER CIRCUITS MADE ON PS-3 KLÖCKNERMOELLER
PROGRAMMABLE LOGIC CONTROLLER – I
The paper presents three variants of bistable trigger circuits with PS-3
(Klöckner-Moeller) programmable logic controller. They have in their
composition two electronic circuits with time-on delay circuits. For each bistable
trigger circuits present the principle accompanied by graphic representations of
the main signals of the bistable trigger circuits, the mode of operation of these
oscillators, and finally, the program achieved on PS-3 programmable logic
controller related signal generators.

21-45 INTENSITATEA CÂMPULUI ELECTRIC ŞI TENSIUNEA DE DESCĂRCARE ÎNTRE ELECTROZII ELECTROFILTRELOR INDUSTRIALE CU PLĂCI

THE ELECTRIC FIELD STRENGTH AND DISCHARGE
VOLTAGE BETWEEN THE ELECTRODES OF INDUSTRIAL
PLATE-TYPE ELECTROSTATIC PRECIPITATOR
This paper presents an analysis on discharge wires and collecting plates
used at industrial plate-type electrostatic precipitators. Electric field strength is
presented (maximum and mean value) and discharge voltage, that voltage
depends on the gas properties and the product between the pressure and
distance.
