Modern electric supply cable is seized of critically important part, but cable due to manufacturing process and construction etc. not
Evitable there is middle interconnecting piece point, and it 80 ~ 90% is since medial head causes that cable, which breaks down,.Cable is often placed in cable
Ditch or using direct buried, the most immediate cause to break down in the process of running are that insulation reduces and breakdown, and causes
The factor of insulation breakdown is mainly primarily due to middle interconnecting piece point by external force damage, running overload, environment temperature
The reason of influence and joint quality problem, cable breaks down from the point of view of summarizing, is mainly influenced by external force and temperature.
For both fault types, by the way of on-line monitoring, give real-time monitoring, breaks down and issue report in time
It is alert, troubleshooting is carried out in time, prevents failure propagation, reduces powered operation risk.
Summary of the invention
The goal of the invention of the utility model is to provide a kind of on-line monitoring by high voltage electric transmission cable transition joint, mentions
Preceding precognition cable fault, is handled in time, is reduced because end defect causes transmission line malfunction, is influenced power supply system and is stablized
Operation.
To achieve the above object, the technical solution adopted in the utility model are as follows:
A kind of high voltage electric transmission cable transition joint operating status on-line monitoring device of the utility model, including among cable
Connector and monitoring system, the cable intermediate joint include cable, the cable intermediate joint for connecting between cable, outer guarantor
Shield, which is characterized in that multiple sensor for measuring temperature are provided on the cable between in the cable in connector, for measuring cable
Temperature at transition joint；Humidity measuring transducer is equipped on outer protective cover, for measuring in cable intermediate joint protective cover
Humidity, in the cable between connector both ends cable be equipped with grip device, on grip device be equipped with displacement sensor, it is described
Sensor for measuring temperature, humidity measuring transducer and displacement sensor the data measured are transferred to external monitoring system
System.
The monitoring system includes data acquisition module, data collection process module, power module and communication network, and
The data of acquisition and processing are transferred to power grid operation personnel's mobile phone or operation of power networks duty room by communication network module.
The communication network module is wired and wireless communication network module.
The utility model has the advantages that: cable intermediate joint temperature, humidity and position are realized due to the above structure,
Move real time on-line monitoring, in time find cable abnormal operating condition, predict cable fault in advance, handled in time, reduce because
End defect causes transmission line malfunction, influences power supply system stable operation.End operation conditions can be effectively monitored, is subtracted
Few cable operation fault, the every loss of personnel, equipment, property etc. caused by reducing because of cable fault, mentions to power grid operation personnel
For reliability service data.
