Abstract

The invention discloses an online monitoring device and method for a drop-out fuse based on IOT (Internet of Things) communication, and the method mainly comprises the following steps: judging that the drop-out fuse drops out when the horizontal angle of a fuse tube of the drop-out fuse is less than a threshold value; and determining that the drop-out fuse is closed when the horizontal angle of the fuse tube of the drop-out fuse is greater than the threshold value. The method can achieve the monitoring of the operation state of the fuse in real time, and the state information of the monitored fuse is transmitted to a background monitoring system. When the fuse is cut off during a short-circuit fault, the method can help a maintainer timely obtain the operation state of the fuse, so as to quickly find out the fault point and quickly restore the normal power supply.

Description

technical field [0001] The invention relates to an outdoor high-voltage protective electrical appliance, in particular to an online monitoring device and method for a drop-out fuse based on Internet of Things communication. Background technique [0002] The drop-out fuse is installed on the branch line of the 10kV distribution line, which can reduce the scope of power outage, because it has an obvious disconnection point of the high-voltage drop-out fuse, which has the function of isolating switch, and creates a safe environment for the maintenance section lines and equipment. The safe working environment increases the sense of security of maintenance personnel. Installed on the distribution transformer, it can be used as the main protection of the distribution transformer, so it has been popularized in 10kV distribution lines and distribution transformers. [0003] Drop-out fuse is an outdoor high-voltage protective device. Because it is more economical and easy to operate...
