Abstract

The application discloses a power cabinet fault positioning device and a use method thereof, and belongs to the electric power field. The power cabinet fault positioning device and the use method thereof are characterized in that the geographic position information of a fault power cabinet is determined through a power grid geographic information system. A worker slides a branch ring out of the inside of a fixed pipe, thereby facilitating observation of whether the inside line of the branch hole is damaged, rotating the rotating ring, thereby adjusting the stress position of the outer end of the cable and the orifice of the main line hole. When the cable breaks down, the semiconductor reduces the penetration of voltage to the inner wall of the connecting pipe, and the heat is transferred to the inside of the storage ring. The stronger the conductivity of the semiconductor is, the higher the temperature of the area where the color-changing temperature-sensitive paper changes color is, thereby positioning the cable fault position.

The heat is transferred to the upper end of the color-changing temperature-sensitive paper, thereby facilitating better identification of the fault area by the worker.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of electric power, more particularly, to an electric power cabinet fault positioning device and a method for using the same. BACKGROUND

[0002] The power distribution cabinet (box) is divided into power distribution cabinet (box) and lighting distribution cabinet (box), metering cabinet (box), which is the last stage of the power distribution system. The power distribution cabinet is the motor control center, which is used in the case of scattered load and less return circuit. The motor control center is used in the case of concentrated load and more return circuit. They distribute the power of a circuit of the upper level power distribution equipment to the nearby load. This stage of equipment should provide protection, monitoring and control for the load.

[0003] The traditional optical cable fault positioning method is that after receiving the optical cable fault notification, the electric power communication maintenance personnel rush to the scene to measure the length from the fault point by using the OTDR (optical time domain reflectometer), and search for the fault point along the optical cable path according to the path of the optical cable. This method has great randomness, and it is difficult to ensure that the fault point is positioned and processed in a short time each time, which leads to the fact that the optical cable fault cannot be recovered in time. Therefore, we need to use scientific means to replace manual on-site search and positioning of the fault point to solve the problem of slow positioning of the electric power optical cable fault point and waste of manpower.
