Nini ni msingi wa safety precautions unayoweza kujitunza wakati wa kutumia mizizi wa mizizi chini?
Explosion-proof Safety：
Shell Inspection：
For flameproof mining transformers, it is necessary to regularly inspect the integrity of the flameproof shell. The flameproof joint surfaces should remain smooth and free from damage, and the flameproof clearance must meet the specified standards. For example, the flameproof clearance is generally required to be within a specified range, such as around 0.1 - 0.2 mm. Any clearance exceeding the standard may lead to the failure of the explosion-proof performance.
The bolts and other connecting parts on the shell should be complete and tightened to prevent loosening during the operation due to vibration or other reasons, which may affect the flameproof effect.
Preventing Internal Faults from Causing Explosions：
It is essential to ensure that the quality and installation of the electrical components inside the transformer meet the requirements to prevent faults such as short circuits and overloads from generating electric sparks or high temperatures. For example, the insulation of the windings should be in good condition to avoid inter-turn short circuits. Meanwhile, appropriate overload protection and short-circuit protection devices should be installed so that when overload or short-circuit situations occur, the power supply can be cut off in a timely manner to prevent the generation of energy sufficient to cause explosions inside the transformer.
Electrical Safety：
Grounding Safety：
Mining transformers must have reliable grounding. The grounding resistance should meet the specified requirements, and generally, the grounding resistance is required to be no greater than 2Ω. Good grounding can lead the current into the earth when leakage or other faults occur in the transformer, thus avoiding electric shocks to personnel.
The grounding devices should be regularly inspected to ensure that the grounding connections are firm and that the grounding electrodes are free from corrosion and other damage. For example, if the grounding electrodes are in a damp underground environment for a long time, they are prone to rust and corrosion, which will reduce the grounding performance and need to be replaced in a timely manner.
Preventing Electric Shocks：
The high-voltage and low-voltage terminals of the transformer should be enclosed or protected to prevent accidental contact by personnel. During maintenance and other operations, the power supply must be cut off first, and a warning sign saying "Someone is working, Do not switch on" should be hung.
Underground operators should be equipped with personal protective equipment such as insulating gloves and insulating boots, and they should receive relevant electrical safety training to be familiar with the operation and safety precautions of the transformer.
