The temperature protection of the power inverter is a key mechanism designed to ensure that the inverter maintains an appropriate temperature range under various operating environmental conditions, thereby improving the reliability, stability and lifespan of the equipment. The internal components of the inverter, such as electronic components and power semiconductors, are temperature sensitive, so measures must be taken to prevent overheating and potential damage.
Temperature Sensor:
The inverter has built-in temperature sensors, which are usually distributed in key electronic components and heat dissipation parts.
The temperature sensor monitors the internal temperature of the inverter in real time and transmits this data to the inverter's control system.
Temperature threshold setting:
The control system sets the maximum temperature threshold at which the inverter can operate safely based on the design specifications and manufacturer's recommendations.
This threshold typically depends on the inverter's construction materials, thermal design, and thermal performance.
Monitor and compare in real time:
The control system determines whether there is a risk of overheating by comparing the internal temperature of the inverter with the preset threshold in real time.
If the temperature exceeds a set threshold, the system is considered to be in potential danger of overheating.
responding speed:
The temperature protection system needs to have fast response characteristics to ensure that corresponding protective measures can be taken immediately when the temperature exceeds the threshold.
Faster response speed helps avoid prolonged overheating and reduces the risk of equipment damage.
Reduce output power:
When the temperature protection system is triggered, one of the usual measures is to reduce the output power of the inverter.
Temperature stress can be effectively mitigated by reducing the time that current flows through sensitive components.
Automatic shutdown:
In extreme cases, when the temperature rises to a level that could cause serious damage to the inverter, the system may choose to automatically shut down the inverter.
Automatic shutdown prevents equipment from operating under over-temperature conditions and protects internal components from damage.
Recovery mechanism:
Once the temperature drops to a safe level, the temperature protection system usually has an automatic recovery mechanism, allowing the inverter to restart and continue normal operation.
Smart fan control:
Inverters are often equipped with cooling fans, and temperature protection systems may involve smart fan control.
Based on changes in internal temperature, the system can adjust the fan speed to improve heat dissipation.
Communication Interface:
Advanced inverters may have the ability to communicate with monitoring systems, transmitting temperature information to external monitoring systems for real-time remote monitoring and fault diagnosis.
