Abstract

The invention relates to a mining centralized control center. The mining centralized control center is characterized in that the mining centralized control center comprises a transformer bank, an upper computer assembly, a communication protection device, a high-voltage isolating switch, a high-voltage contactor set, a lighting transformer and a lighting contactor, wherein an external high-voltage alternating-current power supply is connected with the transformer bank, the high-voltage isolating switch and the lighting transformer, the alternating-current power supply provides electricity for the upper computer assembly after being transformed by the transformer bank, the upper computer assembly is connected with the communication protection device, the high-voltage isolating switch and the high-voltage contactor set through field buses, the high-voltage isolating switch, the high-voltage contactor set and the upper computer assembly are connected through field buses, the lighting transformer is connected with the lighting contactor to output a lighting power supply, and the lighting power supply is connected with a lighting load. The mining centralized control center has the advantages that centralized control requirements of the special environment of an underground coal mine are met, equipment can be installed, used and maintained conveniently, production efficiency is improved, and equipment cost is reduced. The mining centralized control center makes a great contribution to achieving centralized automatic control of the equipment of the underground coal mine.

Description

technical field [0001] The invention belongs to the technical field of mine electrical equipment, in particular to a mine centralized control center. Background technique [0002] Underground electrical control equipment in coal mines includes strong current control equipment, weak current control equipment, and communication control equipment. At present, the above-mentioned various control equipment are installed in a decentralized manner and run independently. With the standardization, rationalization, centralized control of coal mine production and management, and the gradual increase in the requirements for high efficiency of production efficiency, the above-mentioned control methods have revealed many problems: each independent equipment will inevitably lead to inconvenience in use and maintenance, resulting in lower production efficiency. The decline is far from meeting the centralized control requirements in special environments such as flammable and explosive underg...
