Distribution network typical scene comprehensive monitoring device

Abstract

The invention relates to the technical field of power monitoring, in particular to a distribution network typical scene comprehensive monitoring device which comprises a monitoring host and an acquisition terminal, wherein the monitoring host is in wireless communication connection with the acquisition terminal through an antenna, and the monitoring host is in remote wireless communication with arear end through an antenna. The acquisition terminal is fixed on an intermediate joint of a buried cable, and the monitoring host is placed on a cable trench wall of a cable well; the monitoring hostis provided with a data processor, a first temperature sensor, a GPS positioning sensor, a liquid level probe and an infrared probe. A second temperature sensor is arranged in the acquisition terminal; the first temperature sensor, the GPS positioning sensor, the liquid level probe and the infrared probe are all connected with the data processor; the second temperature sensor is in wireless communication with the data processor through an antenna. Operation and maintenance inspection personnel can conveniently master the on-site working condition of the cable intermediate joint at any time, the monitoring work is comprehensive and in place, and the inspection efficiency of the distribution equipment inspection operation and maintenance personnel is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to a comprehensive monitoring device for typical scenes of a distribution network. Background technique [0002] With the rapid development of social economy, the coverage area of ​​urban distribution network continues to increase, and its operating load also increases rapidly. However, urban distribution network has a considerable Part of the distribution network is hidden in the underground cable trench in the form of buried cables. For buried cables, in order to facilitate operation and repair, the cable intermediate joints are often designed in the cable trench, which is the weakest link of the cable. Fire accidents accounted for 40.5%. Japan has investigated electric power, iron and steel, petrochemical and other factories and enterprises, and 78% of the units have had cable fires, of which 40% were accidents with greater hazards. In 2017, China Southern Po...

Problems solved by technology

[0003] On the other hand, at present, the production quality of the cable intermediate joints is uneven, the joints are not tight, and the contact resistance is too large. During the long-term operation, the cable head is overheated and the insulation is broken down, resulting in fire in the cable trench or directly buried cables. safety hazard
