Embodiment Construction
[0016] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. like figure 1 As shown, a small hydropower network outlet monitoring device includes a man-machine interface, a main control system, an alarm module, a monitoring module and a touch screen control module. The man-machine interface is connected to the main control system through a Zigbee network, and the Zigbee In the network, each device has two addresses: one is a 64-bit IEEE physical address, each node has a globally unique MAC address, and the other is a unique 16-bit network address in the PAN, also known as a short address. A network address is assigned to a node by its parent node when it joins the network. The coordinator uses 0x000 as its own short address after establishing the network. After the router and the terminal join the network, they use the short address assigned to it by the parent de...

Description
technical field [0001] The invention belongs to the field of power grid monitoring, and in particular relates to a monitoring device for a small hydropower grid outlet. Background technique [0002] In recent years, with the rapid development of the national economy, the total installed capacity of hydropower in my country has also been greatly developed, especially the number and installed capacity of large-scale hydropower stations have achieved unprecedented development, and the output line capacity and voltage level of the power station have been continuously improved. . As an important equipment for power output of hydropower stations, high-voltage cables are also highly valued for their safety. When the high-voltage busbar is overloaded or the contacts of the high-voltage switch are not in good contact, the contact resistance will become larger and heat will be generated when the load current flows. , This heating phenomenon causes insulation aging or even breakdown, t...
