Load monitoring device for power distribution network

Abstract

The invention relates to a load monitoring device for a power distribution network. The device is used for acquiring the load information of a power distribution network and uploading the load information to a main control computer. The device comprises a monitoring end, a protection end and a clamping module. The clamping module comprises a first clamping handle, a second clamping handle and a fixing buckle. The first clamping handle is connected with the monitoring end. The second clamping handle is connected with the protection end. The fixing buckle is respectively connected with the monitoring end and the protection end, and respectively passes through a first through hole in the first clamping handle and a second through hole in the second clamping handle. The monitoring end comprises a second shell, a sampling assembly and an energy-taking power supply assembly, wherein the sampling assembly and the energy-taking power supply assembly are packaged in the second shell. The sampling assembly and the energy-taking power supply assembly are connected with each other, and are connected with the lead of the power distribution network. Compared with the prior art, the device has the advantages of convenient installation, high sampling precision, wide application range and the like.

Description

technical field [0001] The invention relates to the field of distribution network monitoring, in particular to a load monitoring device for distribution network. Background technique [0002] With the rapid development of distribution automation technology, the requirements for high-efficiency and high-quality power supply of the power grid are getting higher and higher, so it is necessary to monitor the load of the distribution network in real time. The existing monitoring system usually uploads the monitored load information to the main control machine by setting up corresponding load monitoring devices on all levels of the distribution network and communicating with the main control machine. [0003] The existing load monitoring device has the following disadvantages: [0004] 1. It is fixed on the outside of the wire by bolts, which is difficult to disassemble and has high maintenance costs, and it is easy to generate excessive pressure on the wire and cause damage to t...
