voltage AC power supply system should adopt
The AC power cable should adopt copper core cable, and the cable section should suit the load. It is recommended that the power cable outside the power room be buried directly under the ground or by means of cable pipe. Power cable should be wired separately from signal line.
The AC mains voltage shall be within the range of the voltage input range of rectifiers.
The DC power system has a circuit breaker that can cut the AC mains power to it.
2.1.3Site Survey
The power room must be surveyed prior to installation, which should be focused on:
1.Checking the wiring device, including cable chute, wiring rack, floor, wiring holes.
2.Checking the environmental conditions, including temperature, humidity, dust.
3.Checking the conditions for implementing the installation, including power supply and lighting.
2.1.4Tools & Material
1.Tools required for power equipment installation include electric drill, wire cutter, wire presser, various wrenches, screwdriver, electrician knife, and steel saw. The tools must be insulated and antistatic handled before they are used.
2.Power cables for electrical connection include AC cables, DC load cables, battery cables, earth cables, earth bar and lighting connection cables. Their design specifications should be in accordance with relevant specifications in the electrical industry and the materials should be purchased according to the design material list.
AC cables: this system uses
The sectional area of the DC load cables and battery cables should be calculated using the following formula:
A=ΣI×L/K△U
