Electrical distribution method for improving the quality of landscape lighting engineering

Figure 6-1 Luminaire wiring using indoor BV wires

Problem: Use BV cable or rubber cable as the lamp power cable. The cable rubber sleeve is susceptible to heat aging or melting and bonding, forming a short circuit or leakage, which has potential safety hazards.

Requirements: All outdoor lighting pipelines must be YJV or YJV22. The underwater light leads and submersible pump motors must use JHS underwater cables. The outdoor lighting leads can be RVV (as shown in Figure 6-2). Wires replace outdoor cables.

The outdoor cable protection pipe shall be steel pipe, PE pipe or PVC pipe (heavy duty). It shall not be directly buried with KBG pipe or cable (except YJV22). The pipeline depth shall be less than 0.5m. When passing the road and over the wall, additional steel pipe protection is required. .

2. Distribution control system

Figure 6-3 Excessive lighting system for the control loop

Problem: For each circuit of the luminaire, the contactor is controlled and the switch is controlled in time to form too many control loops and control modes. Not only raises the cost of equipment, but also does not facilitate the unified management of the property.

Requirement: According to the control mode requirements, it can be divided into full-open (major festival), partial full-open (festival or weekend), functional opening (the first half of the week), and energy-saving mode (after midnight). Set two to three control modes according to the actual situation. Manual control and timely control, if necessary, increase the light control function. Load two to four time-controlled switches on the control loop and set the corresponding switch time. In order to facilitate the property management personnel to achieve the required opening and closing function with fewer buttons and timely control.

For indoor installation, the control section (or distribution control integrated into a cabinet) is best placed in the guard duty room. The small distribution box is installed on the wall. If the wall is mounted on the duty room, it is recommended to make a wardrobe room to conceal the power distribution box. Large distribution boxes can be installed on the floor. Place indoor corners.

For outdoor installation, it is recommended that the concealed installation or the outer casing be processed into a harmonious color of the landscape. It is not easy to directly expose the stainless steel box to the landscape surface, which affects the look and feel.
