GOST 28904-91 PDF

Full title and description

GOST 28904-91 — "Системы управления электрофильтром. Общие технические требования и методы испытаний" (Control systems of electrostatic precipitators. General technical requirements and methods of tests). The standard specifies functional classification, technical requirements, recommended quality indicators and test methods for control systems used with electrostatic precipitators (ESP), including automatic regulation of supply, rappers (shakers), and heating of insulator housings and hoppers.

Abstract

This interstate (GOST) standard defines the general technical requirements and test methods for ESP control systems — both analogue and microprocessor-based — intended for industrial and export applications. It covers input/output signals, supply parameters, environmental/climatic executions, protection classes and typical performance indicators, and includes recommended procedures for verification and statistical evaluation of measurements.

General information

• Status: Interstate GOST standard (originally adopted by the State Committee for Standards of the USSR); reissued in November 2004. Note: on the territory of the Russian Federation the document is not applied and GOST R 52931-2008 is used in its place.
• Publication date: 1992-01-01 (designation: GOST 28904-91).
• Publisher: Approved and introduced by the State Committee for Product Quality Management and Standards of the USSR; developed by the Ministry of Heavy Machine Building of the USSR.
• ICS / categories: МКС (ICS) 71.120; ОКП 36 4682.
• Edition / version: Original issue 1991/1992 (designation -91); reissued November 2004.
• Number of pages: 22 pages (commonly listed in standards catalogs).

Scope

The standard applies to control systems for electrostatic precipitators, including complex systems intended for automatic regulation of high-voltage power feeding, control of electrode shaking (rapping) and heating of insulator housings and hoppers. It is intended for equipment manufactured for national industry needs and for export; the requirements are recommended (not all are mandatory). The document also sets recommended measurement and test procedures used to validate control-system behaviour under normal and fault conditions.

Key topics and requirements

• Functional classification: ARP (automatic regulation of power), ARV (automatic regulation of rapping), ARO (automatic regulation of heating), and ARK (complex systems).
• Design types: analogue (A) and microprocessor (M) implementations; options for indoor/outdoor installation, cabinet or modular formats, and remote or built-in control panels.
• Electrical parameters: recommended output currents for high-voltage converters (series of values such as 25, 50, 100, 250, 400, 600, 1000 mA. . up to 3000 mA) and specified supply-voltage variants for export versions.
• Input/output signal definitions: voltages proportional to ESP voltage and current, logical signals for technological and emergency shutdown, and control outputs for power switches, rapping actuators and heaters.
• Environmental and mechanical requirements: climatic executions, placement categories and protection classes per referenced GOSTs; vibration and protection levels for different installations.
• Test and measurement methods: procedures for statistical evaluation, test conditions, timing for spark/arc quenching and pulse parameter limits for analogue vs microprocessor systems.

Typical use and users

Manufacturers and designers of electrostatic precipitator control equipment, power-electronics and automation engineers, plant operators in power generation and heavy industry, environmental compliance engineers, testing laboratories and certification bodies dealing with ESP performance and control-system verification. The standard is used as a technical reference for design requirements, factory and site testing, and for specifying exporter options.
