In industrial enterprises, uninterrupted maintenance work is mainly carried out near live equipment or on the shell; in the electrical sector, there are also factory work directly carried out on uninterrupted live objects, such as working with insulating rods and equipotential work. , charged water rinse, etc. The monitoring system must be strictly implemented in the maintenance work without power failure; a sufficient safety distance must be ensured, and the live part can only be located on the side of the maintenance personnel; the maintenance time without power failure should not be too long, so as to avoid accidents caused by distraction of the maintenance personnel; no power failure The tools used for maintenance should be inspected and tested; the maintenance personnel should undergo strict training and be proficient in the technology of uninterrupted maintenance.
The following problems should be paid attention to in the low-voltage live maintenance work: 1) The low-voltage live work should be monitored by a special person, using tools with insulating handles, standing on dry insulating materials when working, and wearing gloves and safety helmets. Must wear long-sleeved clothes to work, and strictly prohibit the use of files, metal rulers, brushes with metal, dusters and other tools.
2) High and low voltage lines are erected on the same pole. When working on low-voltage live lines, the distance from the high-voltage lines should be checked first, and measures to prevent accidental contact with live high-voltage parts should be taken.
3) When the low-voltage live wire is not insulated, the staff shall not cross it. When working on live low-voltage power distribution devices, isolation measures should be taken to prevent short-circuit between phases and single-phase grounding.
4) Before going up the pole, the phase and zero line should be distinguished, and the working position should be selected. When disconnecting the wire, the phase wire should be disconnected first, and then the neutral wire should be disconnected. When bonding wires, the order should be reversed. Generally, it should not be wired or disconnected with load.
5) The human body shall not touch two wires at the same time.
6) Live parts are only allowed to be located on the side of the staff.
