Converter-demultiplexers of APTD series

Electrostatic precipitators are the most effective means of air protection from dust and gases emitted by thermal power plants, cement, chemical and metallurgical plants, mining and pulp and paper mills, and in some cases are technological devices designed to precipitate very valuable volatile substances that are suspended in the exhaust gases.
High-voltage single-phase converter oil units of APTD series are used for supplying ESPs with direct current of high voltage and automatic regulation of ESP operation modes.
The units are connected to two phases of a three-phase network and consist of a high-voltage rectifying device, a high-voltage coupler with a locking system for protection against getting under high voltage of the operating personnel and a microprocessor regulator MEFIS-03.
