Composite sleeve outdoor terminal for oil level on-line monitoring

Abstract

The invention discloses a composite sleeve outdoor terminal for oil level on-line monitoring, and relates to the field of outdoor terminals. The composite sleeve outdoor terminal comprises an insulating sleeve, the bottom of the insulating sleeve is fixedly connected with a bottom plate, the bottom plate is fixedly connected with a liquid level sensor, the lower end of the bottom plate is fixedly connected with a conductor protection sleeve, and the outer surface of the conductor protection sleeve is fixedly connected with a signal control box; and a conductor is in threaded connection with the interior of the conductor protection sleeve, the lower end of the conductor is fixedly connected with an insulating handle, the upper end of the conductor is fixedly connected with a conductor leading-out rod, and the upper end of the conductor leading-out rod is fixedly connected with a conductor connector. The composite sleeve outdoor terminal has the advantages that the liquid level sensor is mounted in the terminal, data is transmitted to an on-line monitoring host, is processed, and is transmitted to a server through a 4G signal, and an alarm is directly given out to inform inspection personnel to overhaul when the data is abnormal, so that the purposes of fault positioning and timely maintenance are achieved, the use safety of the insulating sleeve can be effectively improved, and the working intensity of the maintenance personnel is greatly reduced.

Description

technical field [0001] The invention relates to the field of outdoor terminals, in particular to a composite outdoor terminal for on-line oil level monitoring. Background technique [0002] With the continuous advancement of power grid construction around the world, the global electricity demand is on the rise. In the global power engineering construction, the demand for high-voltage DC cables required for long-distance power transmission is increasing, and the global high-voltage DC cable market is showing a growing trend. Therefore, HVDC transmission technology is becoming an increasingly important technology. As far as the characteristics of HVDC transmission technology itself are concerned, not only the transmission capacity of HVDC cables is twice that of AC cables, but also the transmission power loss is only 40% of that of AC cables, so the transmission distance has been greatly lengthened, and at the same time power supply The stability and reliability have also be...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technical problems, a composite outdoor terminal for on-line monitoring of oil level is provided. The rod connects the floating ball with the liquid level indicating device to achieve the purpose of monitoring the liquid level. It adopts a mechanical connection, which is prone to failure and the sealing effect is not good. The inspection personnel cannot know the leakage of the terminal at the first time. The problem of a large number of manpower for maintenance
