SMD aluminum electrolytic capacitor

The work of non-stop power maintenance in industrial enterprises is mainly carried out in the vicinity of the live equipment or on the outer casing; in the electric industry department, there is also a factory work directly on the electrified body without power failure, such as working with insulating rods and equipotential working. , with water rinse, etc. The maintenance and repair work must be strictly carried out; the safety distance must be ensured, and the live part can only be located on the side of the maintenance personnel; the non-stop power maintenance work time should not be too long, so as to avoid the accidental distraction of the maintenance personnel; no power failure The tools used for inspection and maintenance shall be inspected and tested; the maintenance personnel shall undergo rigorous training and be proficient in the technology of non-stop power maintenance.

Low-voltage live maintenance work should pay attention to the following problems: 1) Low-voltage live work should be monitored by special personnel, use tools with insulated handles, work on dry insulation while working, and wear gloves and helmets. You must work in long-sleeved clothes. It is strictly forbidden to use tools such as knives, metal rulers and metal brushes and edgy. 2) The high and low voltage lines are erected on the same pole. When working on the low voltage line, it is necessary to check the distance from the high voltage line and take measures to prevent accidental contact with the high voltage part. 3) The staff shall not traverse when the low-voltage live conductor is not insulated. When working on a live low-voltage power distribution unit, isolation measures should be taken to prevent phase-to-phase short-circuit and single-phase grounding. 4) Before the upper pole, the phase and neutral line should be separated and the working position should be selected. When disconnecting the wire, disconnect the phase wire first and then disconnect the neutral wire. When lap wires, the order should be reversed. Generally, there should be no load wiring or disconnection. 5) The human body must not touch two thread ends at the same time. 6) The live part is only allowed to be on the side of the staff.
