Street lamp

Street lamp

Streetlights, like guardians of the city, stand in every corner, bringing light to the night. They tower high, their bodies resilient, steadfast in their posts regardless of wind, rain, or thunder. The warm yellow light spills down, illuminating the path home for people and warming every piece of land at night. Streetlights are the compass of the night, guiding those who are lost in the right direction. They are silent yet demonstrate responsibility and commitment through their presence. In this bustling city, the existence of streetlights makes the night no longer dark, bringing safety and hope to people. They witness the city's prosperity and solitude, being an indispensable part of the city.

Embedded parts

Embedded parts

The excavation depth and size of the foundation pit are determined based on geological conditions and must comply with design specifications. All excavated areas will be treated with stone and grouting, and the pouring will meet the relevant standards of GB50010-2002, with deviations controlled within +100mm to +300mm. The length of the anchor bolts embedded in the concrete must be greater than 20 times their diameter, and they should be securely welded to the main reinforcement. The anchor bolts must be free of rust, with the threaded parts protected. The bolts will use double nuts and spring washers. For backfilling the foundation pit, every 300mm of thickness should be compacted once, achieving a compaction level of 80% or more of the original soil density.

The charging principle of a charging pile

The charging principle of a charging pile

The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with charging plugs for charging electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. Users can swipe a specific charging card on the human-machine interaction interface provided by the charging pile to perform corresponding charging operations and print cost data. The display screen of the charging pile can show data such as charging amount, cost, and charging time.

Precautions for Cleaning Photovoltaic Modules

Precautions for Cleaning Photovoltaic Modules

Safety Inspection: Before cleaning the components, check the monitoring records for any abnormal power output entries, analyze whether it may be caused by leakage, and inspect the connection wires and related components for any damage or adhesion. Additionally, use a voltage tester to test the aluminum frame, brackets, and tempered glass surface of the components to eliminate the risk of electric leakage and ensure personal safety.

The role of a solar photovoltaic (PV) controller.

Protecting the battery: Prevent overcharging and over-discharging of the battery to extend its lifespan. When the charging voltage exceeds the protection voltage, the controller will automatically stop charging the battery to prevent overcharging; when the battery voltage falls below the protection voltage, the controller will automatically shut off the output to prevent over-discharging.

The main functions of solar photovoltaic inverters include:

The main function of a solar photovoltaic inverter is to convert the direct current (DC) generated by photovoltaic modules into alternating current (AC) for household or commercial use, allowing the electricity to be smoothly connected to the grid and providing a stable power supply for various electrical devices. The photovoltaic inverter plays a crucial role in solar power generation systems.

BMS (Battery Management System Controller): BMS is the core component for protection and management in the power battery system. It is mainly responsible for monitoring the state of the battery, preventing overcharging and over-discharging, and extending the battery's lifespan. BMS controls the charging and discharging of the power battery pack through contactors and reports the substrate parameters and fault information of the power battery system to the Vehicle Control Unit (VCU).
