Fireworkers understand that weak wires look simple and encounter difficult problems that keep people awake for days. The absence of theory today is a case of real-world warfare, giving a one-off account of the most common and difficult issue of weak wire distribution。
I. Pre-burial blockages, mispositions, lines that can't get through
This is the most common pit. The walls, the floor and the outdoors are either blocked by cement or sunk to the wrong position, the penetrator remains intact and the cost of demolition is too high。
Operational solutions:
Do not croak through the original pipe, first with a wire penetrator + wire + smoother; there is no direct abandonment of the pipe, walk through the catheter or bridge, at a long distance of 5-8 metres; and the outdoor pipe is protected against further sinking。
Ii. Intermittent grounding, good times and bad times
The circuits are normal and malfunctioning, the sound light, the module fail occasionally, and the insulation of the rock surface is slightly low, mostly invisible。
Operational solutions:
The insulation of the circuits was broken off by section, with emphasis on the wire boxes, through the wall, and inside the ceiling. Most of them were self-attacked screws that cut through the cable, and strangulations of the trough. Find a break point to rewiring, strengthen the the thermal concussion, and solve the problem immediately。
Iii. High-level long-range wiring, poor signals, misreporting
High-level, commercial complexes with long vertical distances, combined with elevator wells, powerful electrical wells, frequent dewiring of equipment, delay in connection, and failure of the general bus。
Operational solutions:
Long distance and repeaters; interference zone change-shield lines, only at one end of the control room; super-higher directly on the fibre optic + converter, resistant to jamming force, steady signal and debugged once。
Powerful and weak electricity and wells, systems for direct “battered alarm”
Weak and powerful power cells, too close to each other, and when interference comes up, the mainframe reports malfunctions and false alarms。
Operational solutions:
Powerful and weak electricity must be divided into troughs with metal partitions; shielding lines should be closed to both ends in order to avoid circulation; and lines and equipment casings should be securely connected, far from power cables。
Five: wires are out of order. The system can't be installed
A number of construction teams have managed to save time by replacing the rvs double winch with the bv line, or by too thin a line, leading to smart evacuations, alarm circuits, and very high costs of returning to work。
Operational solutions:
The wdzn-rvs 2x1. 5 is recognized on the bus and does not alter the model; the multiple circuits of the equipment are appropriately followed by a rough line; and the cable is checked before entering the site and does not return from the source。
Weak-wire wires are the only ones caught:
We can't fix the roads
Long distance plus relay. Power and power must be isolated
The cable type is not scrambled。
It's a solid experience, it's a collection, it's a problem, it's a problem
