At present, the electrical operation and maintenance in the distribution room are usually carried out by traditional manual inspection methods, lacking intelligent monitoring of equipment. Service providers are unable to grasp the operating status of the equipment under their jurisdiction, and most of them are repaired and repaired afterwards, resulting in significant losses; After a sudden malfunction, management personnel need to have a comprehensive understanding of the capabilities of operation and maintenance personnel before accurately assigning tasks. The phenomenon of untimely handling and low service efficiency frequently occurs....

In the construction of low-voltage distribution networks, there is still a lack of monitoring methods from public transformers to users, and there is a lack of sufficient data support for the comprehensive implementation of work such as active repair of distribution networks, overload of low-voltage branches, and adjustment of three-phase loads. Transparent construction of low-voltage distribution lines for "distribution transformer line user"....

By detecting fault information such as characteristic current and electric field of the line, the fault type and location can be quickly determined, and an online network diagram can be generated in real time to facilitate user line fault operation and maintenance....

By detecting the current, voltage, switch position, and fault characteristics of the circuit, distributed intelligence is adopted Comprehensive algorithms such as energy and centralized FA are used to achieve automatic fault isolation and power restoration, reducing the size of the system Power outage range, improve the reliability of the power system....

Cable state sensor is an intelligent sensor that combines high-speed signal processing technology and low-power management technology to monitor partial discharge and surface temperature of distribution cable joints. Can be configured at the positions of cable intermediate joints and terminal joints. The entire processing module of the sensor is sealed in a sealed box, with a protection level better than IP68, ensuring accurate detection in harsh environments such as high humidity and immersion. Being able to effectively monitor power cables and reduce the probability of cable failures....

Compared with the distribution network, the structure of 110kV and above high-voltage transmission network is simple. Generally...

Hhcs-6000 environmental monitoring system for cable trench is a newly developed environmental monitoring system for cable trench developed by our company based on the advanced technology at home and abroad and close to the actual needs of the operation environment of cable trench in China. ...

Compared with the distribution network, the structure of 110kV and above high-voltage transmission network is simple. Generally, there is no branch line and no distribution transformer. The occurrence rate of overhead line operation ground fault is relatively high, the line support is generally pole tower, and the cement pole is less, so the ground resistance phase after the ground fault occurs...
