Cable fault correlator and terminal

Abstract

The invention discloses a cable fault correlator and a terminal machine, which include a cable fault correlator software and a terminal built in the terminal, a cloud expert database, a cable fault detector host and several cable fault detection instruments. The terminal receives the state parameters of the cable to be tested input by the user, and displays the first detection method according to the relationship between the first parameter and the preconfigured first condition; Two detection methods, executing the first subroutine corresponding to the second detection method to display the first information corresponding to the second detection method, the first information including the tutorial of using the second detection method. The terminal receives and analyzes the fault waveform transmitted by the cable fault detector host, and obtains typical fault waveforms from the cloud expert database for display. The invention has low requirements on user experience, can quickly get started with various detection methods and instruments, can provide teaching guidance to users, and can improve detection efficiency.

Description

Cable fault related instrument and terminal technical field [0001] The present invention relates to the technical field of cable fault detection, particularly a cable fault correlation instrument and a terminal. Background technique [0002] With the rapid development of my country's economy, the scale of urban construction is getting larger and larger, and the power cable is in the urban power supply system. More and more applications. Power cable failures are also becoming more frequent. However, the current cable fault tester is complicated to operate and requires To judge the waveform, the operator's experience is required. In addition, there are many types of instruments, and it is difficult to master them. [0003] Three steps are required to detect cable faults. There are several instruments for each step. as follows: 1. the first step, the rough measurement of fault distance 1.1 Pulse method (flashover method, time domain method) cable fault tester (includ...

Problems solved by technology

However, some faults cannot be solved by only using the pulse method cable instrument host, high-voltage integration, multiple pulse boxes, path instruments, and acousto-magnetic synchronous fixed-point instruments, and it is impossible to detect all cable faults, which further shows that cable fault detection is a Complicated things require the user to have some experience
