火灾自动保护型漏电断路器及其选型

Fire Automatic Protection Type Residual Current Circuit Breaker and Its Model Silection

为了有效预防火灾,开发了火灾自动保护型漏电断路器。当火灾发生时,环境温度异常升高, 漏电断路器感温头在感测到环境温度达到或超过整定温度后,自动将受控线路电源切断。介绍了火灾自动保 护功能在工程设计中如何选配。

In order to prevent fire effectively, fire automatic protection type residual current circuit breaker was developed. When fire took place, the ambient temperature abnormally rose up. on reaching at or over the set temperature with the ambient temperature. detected by the temperature sensor of the residual current circuit breaker, the breaker would automatically switch off the power for controlled lines. An introduction to how to make selection of fire automatic protection functionality in project design was made.
