Installation And Maintenance Of Outdoor Garden Lights
Outdoor garden lights are used in many places lamps, not only can play the effect of lighting, but also play a landscaping environment, adding bright beauty effect. In the selection of outdoor garden lighting, we must pay attention to the quality of materials, Outdoor Garden Lamp pay attention to the selection of quality and reliable products to ensure that the future can be used normally.
Outdoor garden lights - outdoor garden lights material
Outdoor garden lights of the material, there are three main, one is the aluminum garden lights, one is iron garden lights, there is a common steel garden lights, the three production process is not the same, abrasive is not the same, Duration is not the same, the complexity is not the same, of course, Outdoor Garden Lamp the effect is not the same. Three kinds of material which is better, but also need to look at many aspects.
Outdoor garden lights - outdoor garden lights from the firmness of the selection of materials
In the outdoor courtyard lamp material, the low boiling point of aluminum, Outdoor Garden Lamp flexibility and strong, easy to deformation at high temperatures, relative to the steel, the firmness is slightly worse. It is generally not recommended to use in windy areas. The steel wall thickness can be increased, high stability, strong support, wind resistance up to 36km / s, earthquake 8.8 above.
Outdoor garden lights - outdoor garden lights from the work picking materials
Outdoor garden lights from the work point of view, different materials, is not the same. Cast aluminum and cast iron work more complex than the iron and steel materials, Outdoor Garden Lamp aluminum outdoor garden lights, in the specific operation of the time, is the first to burn aluminum liquid, and then through a special abrasive will be liquid into the middle Re-aluminum rods on a variety of carving patterns, to be dry after the galvanized spray. Duration and complexity are more than steel materials. Outdoor Garden Lamp The steel material is only steel plate through the shears cut into the required cone plate, and then rolled into a poles by rolling machine, and then through welding, grinding and other processes to its beautiful look, after the completion of galvanized spray.
Outdoor garden lights - outdoor garden lights from the price selection of materials
Outdoor garden lights of different materials, Outdoor Garden Lamp the price difference between a lot. Cast aluminum production process is complex, high cost of materials, peculiar shape and so on several advantages, so the price is higher than the steel material of the courtyard lamp 3 times -6 times is normal.
Outdoor garden lights are the main materials described above, which should be selected, the user also needs from the performance characteristics of each material, workmanship, aesthetics, firmness and price of several aspects to comprehensive comparison, So as to select the most satisfied with their products. Suitable outdoor garden lights are used well and have good aesthetics.
Outdoor garden lamp installation and maintenance program
(1) lamps, light according to the design requirements, Outdoor Garden Lamp all lamps should have product certification, light wiring is strictly prohibited, lighting accessories complete.
(2) According to the installation site to check whether the lamp meets the requirements, check the wiring within the lamp, lighting installation must be solid, correct location, neat appearance, wiring is correct. 3KG above the lamps must be pre-magnesium hook bolts, less than 2.4M lamps of the metal shell should be grounded.
(3) the installation is completed, telemetry of the branch of the junction resistance qualified, the side allowed to run. After the phone should be carefully checked whether the control of the lamp is flexible, ready, switch and lamp control sequence corresponds to, such as the problem must first power, and then find the reasons for repair.
Grounding protection and safety measures
(1) grounding protection adopt TT way, in the indoor lighting box around the set of closed yellow-shaped artificial grounding device, the grounding pole with 50 * 50 * 5L2500 hot-dip galvanized angle, the connection line with 40 * 4 hot-dip galvanized flat steel, 5m, buried 0.8m, grounding resistance is not greater than 10 ohms.
(2) all the lamps in the system grounding terminals are connected by the PE line after the connection with the lighting box PE busbar and ground.
(3) for lightning protection over voltage, in the outdoor lighting box are set up a surge protector.
We are in the daily use of the garden lights maintenance, often encountered in the courtyard lamp failure led to the normal use of garden lights or affect the use of effects and functions. In recent years, we summed up a few common few common faults, that is, the cable was blown, the instrument measuring resistance is large, or phase or ground insulation drop, but there is a certain resistance
The other is low resistance failure. The so-called low-resistance fault, that is, short-circuit or to the ground completely shorted, the current increases, power transmission trip phenomenon. These two failures and their frequent occurrence of the normal use of the garden lights constitute a threat. Therefore, we must cause our attention enough to identify the causes of failure and solve the problem of failure.
