Problems solved by technology

[0004] Cable is a facility with a high probability of failure in the cable network. The existing detection method is that when the cable is powered off for maintenance, the monitoring personnel go to the site to use offline measuring instruments to detect one by one. Inherent disadvantages such as continuity

Abstract

The invention provides a cable on-line monitoring device for wireless transmission, belongs to the technical field of electric power systems, and particularly relates to the cable on-line monitoring device for wireless transmission. Measured signals are extracted through current sensors, amplified and filtered through amplifying and filtering circuits, and transmitted to a singlechip through sampling circuits, and the singlechip can assemble the signals into a fixed message format for transmission, so that the defects such as long measurement period, large measurement workload, less measurement data, no continuity and the like in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to an on-line cable monitoring device for wireless transmission. Background technique [0002] With the increasing investment in national power infrastructure year by year, the length of power tunnels is also increasing rapidly. Since the growth rate of operation and maintenance personnel is far behind the growth rate of power infrastructure, the operation of power tunnels is facing enormous pressure. Furthermore, with the accelerated development of cities, the rapid growth of power channels and high-voltage pipelines, and the sharp increase in power load, power companies are facing enormous pressure on the operation and maintenance of tunnels. How to ensure that the cables in the tunnel do not suffer sudden large-scale operation safety accidents due to overload, overheating, etc., and new requirements such as water accumulation and flammable gas in the tunnel will no...
