Abstract
본 발명은 과전류에 합리적으로 대응할 수 있는 가로등용 과전류 제어방법에 관한 것이다.The present invention relates to an overcurrent control method for a street lamp that can reasonably correspond to the overcurrent.
본 발명은 가로등 램프에 흐르는 전류를 검출하여 이값이 과대 전류 이상의 값인지를 판단하여 스위칭 소자의 제어여부를 결정하며 전류값이 이상전류범위의 값인가를 검사하여 이상전류범위의 값인 경우에는 설정시간이 경과하였는지를 살펴본후 전류값이 계속 이상전류범위의 값인 경우에는 스위칭 소자를 제어하여 전원을 차단하며 전류값이 이상전류범위의 값이 아닌 경우에는 과대전류가 아닌한 스위칭 소자의 도통상태가 유지되도록 하여 전체회로를 보호함과 동시에 불필요한 점소등으로 인한 생활의 불편을 방지할 수 있도록 한 것이다.The present invention detects the current flowing in the street lamp lamp to determine whether this value is greater than the excess current to determine the control of the switching element, and check whether the current value is the value of the abnormal current range setting time when the value of the abnormal current range After checking whether this value has passed, if the current value is still in the abnormal current range, control the switching element to cut off the power. If the current value is not in the abnormal current range, keep the conduction state of the switching element as long as it is not excessive current. It protects the whole circuit and prevents the inconvenience of life caused by unnecessary flash.
