Problems solved by technology

When the existing low-voltage switchgear is overhauled, professionals (such as manufacturers) are required to judge the specific problems of the instruments of the low-voltage switchgear. If the instrument needs to be replaced, the manufacturer needs to be notified again to deliver the replacement instrument. This solution has high requirements for personnel, and, Therefore, the cost of instrument maintenance of the existing low-voltage switchgear is high

Abstract

The invention provides an instrument overhauling method and apparatus of a low-voltage switch cabinet. The method comprises the following steps of a tablet computer sends position coordinates and a model number of the low-voltage switch cabinet to a network side device; the tablet computer receives an overhauling video file and an overhauling vector corresponding to the low-voltage switch cabinetreturned by the network side device, wherein the overhauling video file comprises multiple detection steps; the tablet computer plays the video file according to the detection steps, establishes a connection with a detection device, and the tablet computer executes a data verification operation once playing a detection step; and the tablet computer obtains all elements of an input vector after playing all steps of the video file, executes a vector product operation on the input vector and the overhauling vector to obtain an operation result, predicts a fault point of the low-voltage switch cabinet according to an interval wherein the operation result is located, and sends the fault point to the network side device. The technical scheme provided by the invention has the advantage of low cost.

Description

technical field [0001] The present application relates to the electrical field, in particular to a method and device for instrument maintenance of a low-voltage switchgear. Background technique [0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries, as power transmission, power distribution and power conversion. When the existing low-voltage switchgear is overhauled, professionals (such as manufacturers) are required to judge the specific problems of the instruments of the low-voltage switchgear. If the instrument needs to be replaced, the manufacturer needs to be notified again to deliver the replacement instrument. This solution has high requirements for personnel, and, Therefore, the instrument maintenance cost of the existing low-voltage switchgear is high. Contents of the invention [0003] The object of the present invention is to provide an instrument maintenance met...
