Abstract

The invention provides a mine downhole power transformation chamber and a construction method. The mine downhole power transformation chamber comprises a chamber sealing retaining wall, an automatic control unit, an axial flow fan and an air purifying device. The power transformation chamber is a fully-sealed space, the chamber sealing retaining wall is arranged at the position where the chamber is connected with a mine tunnel, a chamber sealing door is arranged on the middle-lower portion of the chamber sealing retaining wall, an air outlet is formed in the upper portion of the chamber sealing retaining wall, and an air inlet is formed in the bottom of the chamber sealing retaining wall. The air purifying device is arranged at an inlet of the axial flow fan, and an outlet of the axial flow fan is connected to the air inlet. The automatic control unit is connected with the air purifying device. By implementing the mine downhole power transformation chamber and the construction method,the indoor environment of the power transformation chamber can meet the requirements of the mounting and working environment for mine downhole precision electrical appliance equipment, unattended operation and automatic control can be achieved, and a control system involved in the mine downhole power transformation chamber is high in safety, low in operation cost and capable of being reasonably applied and implemented in various complex mine downhole exploiting environments; and good popularization prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of mining, and relates to a chamber of power transformation equipment, in particular to a mine underground power transformation chamber and a construction method. Background technique [0002] At present, in the process of ore mining in mines, it is often necessary to use a variety of electrical equipment, and some electrical equipment has high requirements for the working environment, and the mine cannot meet its use requirements. Taking the frequency converter as an example, the ambient temperature needs to be 0 -40°, conductive dust is not allowed in the working environment, and the relative humidity is less than 95%. In addition, the inverter should be installed vertically, away from vibration, heat dissipation and condensation. The installation surface should be smooth and firm, and there should be enough space around the module. Ventilation space, but for the working environment in the mine, it cannot ...
