I. Construction readiness
1. Safety readiness: accomplishment of a basket, a board, a safety rope, an anti-crash device, a double hook seat belt. Under the chimney there are security zones, shelters, specially supervised, and non-observed persons are prohibited from entering。
2. Material preparation: aerial barrier lamps, waterproof interfaces, cables, wiring terminals, fixed racks, seals, insulation tape, etc。
3. Technical preparation: familiarization with the location of the light installation, the direction of the power supply line and the manner of control. Preliminary determination of the type of lamp failure。
Ii. On-site inspection and fault determination
1. Appearance check of lamps: whether the lamps are broken, water entered, yellowed, ageing. Whether the lamp is deformed, fixed loose, rusty。
2. Line inspection: cable failure, ageing, short circuits, water intake. Whether the end of the connection is oxidized, loose or incinerated。
Control and electrical inspection: check the normality of control boxes, time control, optical control modules. Measurement of the stability of electricity voltage。
Iii. Maintenance steps
1. Power outages: the power supply of the barrier lights is cut, locks are placed on the tablets, and electrical operations are strictly prohibited。
2. Dismantling old lamps: unlocking fixed bolts and carefully removing old lamps and lamps. Cleans up installation bases and keeps them dry and clean。
3. Replacement or repair of lamps: replacement of damaged lamps, selection of same model, same specification, same protection grade products. Rewiring, replacement of terminals, repair of damaged cables, if only the lines fail。
4. Re-installation of new lamps: the lamps are secure, unshakable and unslanted. Waterproof seals, waterproof connections, sealed glues, access points。
5. Routine restoration: rewiring, end-pressure solid, insulation secured. Cables are fixed straight along the wall to avoid wear and tear。
Water protection and preservation: preservative treatment of lamps underseas, supports, metal parts. Ensure that all interfaces are sealed in good order to prevent infiltration of rainwater。
Electro-debugging
1. Reactivate electricity and conduct electrical testing。
2. Check the brightness, flash frequency and synchronity of the lamps。
3. Check whether there are problems of scintillation, insinuation, mist。
4. Tests for normal light control, time control。
Quality requirements
1. Lights are strong, vertical and free。
2. Sealed well, waterproof and dustproof。
3. The lighting and frequency of the lights meet the specifications for air barrier lamps。
4. Lines are reliable, there are no short circuits and electricity leaks。
Security concerns
1. High-altitude operations shall include two-lined safety belts and high-mounted low-use。
2. High-altitude parabolics are prohibited by means of means。
3. Electrical operations have severe power cuts, listing and locking。
4. Construction was stopped in the event of heavy winds, thunderstorms and fogs above class 6。
5. The site is equipped with insulation tools and insulation gloves。
