Technicians Tell You: What Is the Construction Scheme of Solar Street Lamps
Today, solar street lamps not only illuminate the road for people, but also save energy consumption for national energy consumption. They are not only environmental protection products, but also cost saving and contribute to the country.1. Selection of disassembly and assembly location: the disassembly and assembly location shall be near the installation location to facilitate transportation after assembly. In addition, the installation point shall be paved with rainproof cloth to place the wear, scratch and stain caused by the bulge or fine sand and stain on the ground.2. Installation personnel and tools: there are 3-6 professional installation personnel (personnel can be appropriately increased for heavy installation tasks), and each person is equipped with a set of installation tools, including a multimeter, a large movable port (installing anchor nuts) and a small movable port (installing other nuts), a flat screwdriver, a triangular lock tooling, a cross screwdriver and a pointed nose pliers, several rolls of insulating tape and waterproof tape, etc. In addition, there must be a crane and a lift truck.3. Count the lamps according to the delivery list: disassemble and check all parts one by one with reference to the packing list, and check whether there is any damage such as collision, wear, deformation and scratch. The installation of unqualified products is prohibited.4. The lamp pole components and easily worn accessories (components and lamp caps) must be padded with soft pads to avoid unnecessary damage such as scratches during installation.5. When the lower lamp pole assembly is placed, its upper end must be supported by an iron frame to facilitate the installation of the upper lamp pole assembly.1. Assembly of lamp pole assembly: upper lamp pole assembly, lower lamp pole assembly, lamp arm assembly and solar cell assembly fixing structure.A. Install the lamp arm: bind the exposed sheath wire end on the lower lamp pole with thin iron wire and wrap it with black tape: the other end of the thin iron wire passes through the lamp arm assembly; Slowly pull the thin iron wire at the top of the lamp arm assembly so that the thin iron wire with the movable sheath wire passes through the lamp arm assembly. At the same time, the lamp arm assembly gradually approaches the lower lamp pole until the panel on the lamp arm is aligned and close to the lamp arm boss on the lower lamp pole, and then fasten the lamp arm assembly on the lower lamp pole with appropriate bolts; When fixing the lamp arm assembly, avoid squeezing the sheath wire, resulting in damage or even cutting of the sheath wire skin; Disconnect the thin wire from the sheath.B. Installation of lamps (equipped with equal source): close the opened lamps to the upper end of the lamp arm, and the exposed sheath wire passes into the lamps from the tail of the lamps; Pull the sheath wire and insert the lamp into the lamp arm at the same time. The overlapping length of the two is 150mm; Connect the sheath wire to the wiring terminal inside the lamp, and pay attention to the correct positive and negative wiring during wiring. Rotate the lamp with the lamp arm as the neutral so that the lampshade is facing the ground, and then fix the lamp on the arm; Turn off the lights.C. Pole assembly on assembly:1) Fasten the bracket assembly and corner post on the upper lamp post assembly in turn, and the threaded connection parts shall be stressed evenly and fastened; While connecting the support and the angle steel frame, use fine iron wire to lead the sheath wire from the lamp pole to the angle steel frame through the support assembly;2) . place the component guard in the angle steel frame, and then place the component on the guard; When placing the components, the junction box shall be at a high place. When the components are placed horizontally, the junction box shall be close to the light pole assembly;3) . connect the components according to the system voltage and component voltage of the street lamp. If the system voltage of the street lamp is 24V and the component voltage is 17V or 18V, the components shall be connected in series. The series connection mode is that the positive pole (or negative pole) of the first component is connected with the negative pole (or positive pole) of the second component. If the component voltage is 34V, the components shall be connected in parallel, The parallel method is to connect the positive and negative poles of the first component and the positive and negative poles of the second component correspondingly. When connecting, press the small slotted screwdriver to the terminal of the junction box. The red wire is required to connect the positive pole and the blue wire to the negative pole. After wiring, fasten the anti nut at the outlet end of the junction box, and apply 7091 sealing silica gel at the terminal of the junction box, The amount of glue shall be subject to the complete sealing of the incoming line in the junction box, and then the junction box cover shall be fastened without reverse buckle.4) Use a multimeter to detect whether the component wiring (connected to the controller end) is short circuited, and also to detect whether the component output voltage meets the system requirements. In fine weather, the open circuit voltage shall be greater than 18V (system voltage is 12V) or 34V (system voltage is 24V). After installing and testing the components, the power line is connected to the positive pole of the controller end, and the exposed wire core shall be wrapped with insulating tape, which shall be wrapped in two layers;Note: the components shall be handled with care during installation to avoid damage to them by tools and other instruments.5) , components and component supports are fastened with M6 * 20 bolts, N6 nuts and washers 6. During installation, the bolts shall be installed from the outside to the inside, and then the washers shall be sleeved and fastened with nuts. During fastening, the bolt joints shall be firmly connected without looseness.
