[0041] The microcomputer control module adopts single-chip microcomputer STM32F407ZGT6. Its core is a 32-bit high-performance ARM Cortex-M4 processor with a clock of up to 168MHz. It has high-precision ADC sampling and fast calculation processing capabilities. It is main...

Embodiment 2

[0053] Such as figure 2 As shown, the fault monitoring method of the dropout fuse online monitoring device is:

[0054] Install a state acquisition unit on the drop-out fuse to monitor the inclination and temperature of the fuse tube, and then transmit the data information to the collection unit through short-distance wireless communication. The collection unit uses the edge computing module to analyze the data, and the edge computing judges the fuse tube Whether the tilt angle θ is greater than the threshold value, with the horizontal line as the reference zero point, the threshold value is in the range of -90°~90°:

[0055] If the inclination angle of the melting tube is less than the threshold value, it is judged that the melting tube has fallen;

[0056] If the inclination angle of the fuse tube is greater than the threshold value, it is judged whether the temperature of the fuse tube is greater than the threshold value, and if it is greater than the threshold value, it ...

Embodiment 3

[0061] Such as Figure 4 As shown, a computer device provided by the present invention includes an electrically connected memory and a processor, wherein the memory stores a calculation program that can run on the processor, and when the processor executes the calculation program, the above-mentioned The steps of the fuse state monitoring method.

Abstract

The invention discloses a drop-out fuse state monitoring method, device, equipment and medium, and the main implementation process of the monitoring method is as follows: a state collection unit is additionally arranged on a drop-out fuse to monitor the dip angle and temperature of a fuse tube of the fuse, and then data information is transmitted to a collection unit through short-distance wireless communication, the collection unit analyzes the data through an edge calculation module, when the analysis result is that a fuse is fused or a fuse drops, alarm information is generated, and a wireless communication module of the collection unit sends the alarm information to a power distribution master station and a mobile terminal through a 4G network, so that operation and maintenance personnel can master the fault condition in time, and a fault point can be quickly reached to be overhauled.

Description

technical field [0001] The invention belongs to the technical field of outdoor high voltage protection, and in particular relates to a method, device, equipment and medium for state monitoring of a dropout fuse. Background technique [0002] Drop-out fuses are generally installed on branch lines of 10kV distribution lines. When drop-out fuses drop and disconnect, there is an obvious disconnection point, which has the function of an isolating switch, creating a safe operation for the maintenance section lines and equipment. environment, which increases the safety of service personnel while they are troubleshooting. 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] Especially at the point where the user is connected to the power grid, a high-voltage drop-out fuse is often used as an obvious breaking point. After long-te...
