T/CCIAC 002-2022 Low-voltage reactive power compensation technology guidelines for coal-bed gas plants

Scope

Scope: This document specifies the design principles, design basis, general design requirements, design methods, installation and arrangement, construction and trial operation, and evaluation methods for the acceptance of low-voltage reactive compensation devices for electrolytic furnaces. This document applies to new, modified, and expanded low-voltage reactive compensation devices (hereinafter referred to as "devices") for electrolytic furnaces operating at 50 Hz and with a rated voltage of 1 kV or lower. The design, installation, construction, and trial operation of the devices, in addition to complying with the provisions of this document, shall also comply with the relevant national standards and safety regulations. Main technical content: I. Relevant terms II. Electrical equipment III. Low-voltage parallel capacitor compensation short network for electrolytic furnaces 1. At the connection point of the compensation short network and the electrolytic furnace short network, the copper tubes should be connected after being combined into a common circuit. When making the combined circuit, all the copper tubes of the secondary outlet of the electrolytic furnace transformer should be combined together. The connection points should be welded with short copper busbars, and then the two copper busbars should be connected by bolts. The cross-sectional area of the combined copper busbars should not be less than the designed cross-sectional area, and the current density should not exceed 3 A/mm2. 2. For the water-cooling system of the copper tubes of the compensation short network, the length of the high-pressure rubber hoses connecting the copper tubes of different phases should not be less than 1 m. Each phase can have an independent water circuit, or multiple phases can share a single water circuit. 3. The compensation short network copper tubes should be equipped with: temperature detection, water-pressure detection, and corresponding alarm devices. 4. After the in
