Abstract

The invention relates to the field of a debugging method of a metallurgy equipment electric system, in particular to an electric debugging method of a dry-quenching power distribution system. The electric debugging method of the dry-quenching power distribution system comprises the following steps: a, inspection of equipment appearance; b, correction and inspection of cable wiring; c, test of a transformer; d, test of a high-voltage switch cabinet; e, test of a relay protection unit; f, high-voltage holding test of the transformer; g, high-voltage holding test of the system; h, setting of relay protection; I, test of system blank operation; j, test of a high-voltage cable; k, debugging of a low-voltage power distribution disc; l, inspection of low-voltage trial power transmission; m, electrification and operation of high voltage; n, power transmission and operation of the transformer; o, electrification and operation of a low-voltage disc; and p, recording and arrangement of debugging. In the invention, through the strictly-designed standard installation and detection reference, the debugging method is simple, safe and reliable and has high work efficiency.

Description

technical field [0001] The invention relates to the field of debugging methods for electrical systems of metallurgical equipment, in particular to an electrical debugging method for CDQ power supply and distribution systems. Background technique [0002] Dry coke quenching is a newly born smelting energy-saving technology in the world. Its English name is Coke Dry Quenching, or CDQ for short. CDQ uses circulating inert gas as the heat carrier, and the circulating fan sends the cold circulating gas into the red coke cooling chamber to cool the high-temperature coke to below 250°C and discharge it. The circulating hot gas after absorbing the heat of coke is introduced into the waste heat boiler to recover heat and generate steam. After the circulating gas is cooled and dedusted, it returns to the cooling room through the fan, so that the red coke is cooled in this way. The steam generated by the CDQ boiler is either integrated into the steam pipe network in the plant or sent...
