The system is a distributed monitoring, centralized management and instant notification mode with long-distance transmission capability. ...

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"....

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. ...

Hh-1200 intelligent anti condensation environment control system is an anti condensation environment control device that can be used in distribution box, switch cabinet, terminal box and various outdoor small environments. It adopts advanced semiconductor refrigeration technology to dehumidify in the low temperature area of 2 ℃ - 20 ℃, that is, the temperature area where condensation is most likely to occur....

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...
