Problems solved by technology

Due to the lack of strong and reliable evidence, the real situation at the time of the failure cannot be reproduced, so unexplained failures occur from time to time
If the real cause of the fault is often uncertain, it will be difficult to effectively avoid the same type of fault, which will easily lead to the recurrence of the same type of fault, leaving a safety hazard for the operation of the transmission line

Embodiment Construction

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as figure 1 As shown, the transmission line (AB) has a beginning (A) and an end (B), wherein the failure point (C) is located between the beginning (A) and the end (B); when a failure occurs, the failure point (C) ) An arc will be generated. The visible light, infrared, ultraviolet and sound characteristics of the arc are monitored by the distributed monitoring arc device, and the fault point (C) of the transmission line (AB) is found and located based on the characteristic value, and then the fault is analyzed The reason; the method includes the following steps:

[0041] Step 1: Divide the transmission line (AB) from the beginning (A) to the end (B) into M-1 sections, and install M monitoring arc ...

Abstract

The invention relates to a power transmission circuit fault positioning and reason analysis method based on distributed monitoring of arcs. The technical problem to be solved is to provide the power transmission circuit fault positioning and reason analysis method based on distributed monitoring of arcs. The premise hypothesis is that: after a power transmission circuit breaks down, fault points will generate arcs due to the faults, so if the fault points fail to generate arc, the method is invalid. The power transmission circuit is provided with a starting end and a terminal end. The fault points are arranged between the starting end and the terminal end. When the fault occurs, the fault points will generate arcs, and through the feature quantity of visible light, infrared light, ultraviolet light and sound of the arcs monitored by distributed arc monitoring devices, the fault points of the power transmission circuit can be found and positioned based on the feature quantity, and fault generation reasons can be analyzed. According to the invention, remote inspection on the faults of the power transmission circuit can be achieved; traditional inspection efficiency is increased; and labor cost for the inspection is reduced.

Description

Technical field [0001] The invention relates to a transmission line fault location and cause analysis method based on distributed monitoring arcs, and mainly realizes the transmission line fault location and fault cause analysis through distributed monitoring of arc shape characteristic quantities generated at fault points of the transmission line. Background technique [0002] With the development of the power system, the voltage level and transmission capacity of the power system transmission line are constantly improving, and the accurate location and rapid analysis of the cause of the transmission line failure are also more and more important. The accurate location of the fault helps line inspectors to quickly find the location of the fault, and the analysis of the cause of the fault is very important to quickly restore the operation of the transmission line, implement personnel responsibilities and avoid the recurrence of similar problems. [0003] So far, there have been a la...
