First, the mine flameproof electrical equipment can be used in the coal mine, and its explosion-proof mark is ExdI. The flameproof electrical products shall be installed and used in accordance with the relevant provisions of the "Coal Mine Safety Regulations" and the working conditions required in the product operating instructions.
2. During the acceptance, it shall check whether the product has an effective mining product safety mark and product ex-factory certificate, and whether the relevant information reflected in the product nameplate is related to the content marked in the safety mark certificate (including the product name, model number, and safety mark number). The production unit, address, etc.) are the same, and the safety signs are marked in the certificate for which the safety signs are required to have valid safety signs. The product safety warning sign boards are complete, clear, and complete.
Third, the volume is greater than 2000cm3, shell material is cast iron flameproof electrical equipment , shall not be used for mining work surface.
Fourth, before going down the need to check the product flameproof parameters: the length of the explosion-proof surface, the surface of the explosion-proof surface, the gap between the explosion-proof surface (the gap between the explosion-proof surface should be checked after the cover is covered or closed), electrical clearance , creepage distance (in the most severe conditions, whether to meet the requirements after wiring), the introduction of the device (rubber ring meets the requirements), etc., meet the requirements before being put into use.
5. All products that are grounded internally or externally must be properly grounded.
6. For the electrical equipment with protection function, the protection setting value shall be adjusted according to the parameters required by the product specification.
VII. Before use, the product protection function should be checked whether it is normal, whether the action is flexible, whether the lock is reliable, and whether the display is correct and meet the requirements before it can be put into use.
VIII. According to the instructions for use of the product, such as “Limiting the opening with live power†or “Disconnecting the power for XX minutes before opening the coverâ€, etc., it must not be operated by electrification or relocation of explosion-proof electrical equipment.
