Problems solved by technology

However, due to the high working voltage level of the insulated bucket arm truck, the leakage current is small, and other safety factors are usually not considered, the Chinese patent announcement number CN110579673B discloses a leakage current measurement and control system and method of the insulated bucket arm truck. By setting the leakage current measurement device, When it is greater than the threshold, it is judged that there is a leakage current safety fault
In some cases, once a leakage current fault occurs, it may bring great potential safety hazards to the operators at this time.
Therefore, there is a lack of methods and devices that can provide safety warnings when the leakage current has not exceeded the standard, and live operators face huge operational safety risks

Embodiment 1

[0038] like figure 1 As shown in the figure, the present invention discloses a method for detecting the state of an arm truck based on historical data during live work. By setting a leakage current measuring device, the leakage current is measured, the specific situation of the leakage current is judged, and the Normalization operation. In addition, on this basis, through the analysis of the service life of the bucket truck and the set life threshold, the preventive test data of the last three years and the qualified threshold, and through the mixed analytic hierarchy process, the above-mentioned service life, the last three years are analyzed. The preventive test data is normalized, so as to comprehensively analyze the safety situation of the arm truck at this time by means of factor analysis weight method, and set at least two thresholds, when the leakage current exceeds the first threshold, the leakage current The online monitoring device will give a warning, stop the test...

Embodiment 2

[0050] like figure 2 As shown in the figure, the present invention discloses a state detection device for a boom truck based on historical data during live work.

[0051] A state detection device for bucket arm trucks based on historical data in live work includes five modules: a bucket arm truck leakage current measurement module, a spectrum intelligent analysis module, a comprehensive evaluation module, an alarm module, and a power supply control module. The module is used to measure the leakage current of the bucket arm truck; the spectrum intelligent analysis module is used to judge the specific situation of the leakage current and normalize it; the comprehensive evaluation module is used to measure the leakage current of the bucket arm truck. The years of use and the set thresholds of years, the preventive trial data of the last three years, and the analysis of the qualified thresholds, and the mixed analytic hierarchy process was used to normalize the above-mentioned ye...

Abstract

The invention discloses a method and a device for detecting the state of a bucket arm vehicle based on historical data in hot-line work, which belong to the technical field of hot-line detection, and are characterized in that a leakage current measuring device is arranged to measure the leakage current, judge the specific condition of the leakage current and perform normalization operation on the leakage current. In addition, the leakage current detection device also records the service life of the boom truck, a set service life threshold value, preventive test data of the last three years and a qualified threshold value, and normalizes the service life and the preventive test data of the last three years through a hybrid analytic hierarchy process, so that the leakage current of the boom truck is obtained through a factor analysis weight method. According to the method, the safety condition of the boom truck at the moment is comprehensively analyzed, and at least two layers of threshold values are set, so that power-off operation or test stopping operation is carried out, the state of the boom truck can be determined under the condition that the leakage current does not exceed the threshold values, and the safety performance of hot-line work is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of live work, and in particular relates to a method and device for detecting the state of an arm truck based on historical data in live work. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In recent years, with the rapid development of the national economy and the continuous improvement of people's living standards, the requirements for the reliability of power supply have become higher and higher, which has led to the widespread application of live operation technology in distribution networks. The insulated bucket truck is currently the most widely used tool for live work in the distribution network. The bucket arm truck can usually carry out live aerial work on lines greater than 10 kV. Its working bucket, work, control oil circuit and line, and bucket arm joints can ...
