Fault Analysis of Taiyuan Elevator Inverter Maintenance
Professional inverter maintenance services in Taiyuan, including soft starters, PLCs, instrumentation, touch screens, and industrial control products. We offer installation, commissioning, and repair services for inverters, as well as authorized sales of brands like Sanjia (Three Crystal) and Yingwei Teng. We are a designated repair center for Siemens and ABB inverters, with a large inventory, low maintenance costs, and high-quality service.
During our extensive experience repairing elevator inverters, we have noticed that many failures are caused by high ambient temperatures. Elevator frequency converters are typically installed in the top control room, which is often exposed to direct sunlight during summer. The heat generated by the inverter itself, along with the braking resistor, can cause the temperature inside the electrical room to rise significantly. This high temperature accelerates component aging and reduces the lifespan of electronic parts, especially for inverters. To prevent this, proper insulation and ventilation should be considered during the design phase—such as using hollow bricks for walls and multi-layered roofs. Installing an air conditioner in the electrical room can significantly extend the life of the inverter.
If the inverter cabinet is installed in a hot environment like Xiamen, it's important to open the cabinet door to improve cooling. Many manufacturers design their cabinets too small, without even installing a cooling fan. This leads to poor heat dissipation and increases the risk of failure.
Regular maintenance of elevator inverters is essential. Since modern elevators rely heavily on inverters, any failure can cause inconvenience and frustration for building management. Proper maintenance can greatly reduce the failure rate. After repairing numerous elevator inverters, we've identified several key points to focus on: 1) Keep the electrical room temperature under control—air conditioning is highly recommended. 2) Prevent water damage from rain, especially during typhoons when doors may be blown open. 3) Ensure proper lightning protection, as inverters hit by lightning can suffer severe damage. 4) Clean or replace the inverter’s cooling fan regularly. 5) Monitor the motor’s sound; unusual noises often indicate inverter issues. Unbalanced three-phase currents should be addressed immediately to avoid serious damage. If you lack maintenance experience, do not attempt repairs yourself—many people end up worsening the problem. For example, a Fuji VG5 inverter from Guangri Elevator was sent to us for repair twice, only to burn out its module after a few days due to poor cooling. The root cause was improper application of thermal paste on the module base.
