Description

Technical Field

[0001] The utility model relates to the technical field of power emergency repair, in particular to a device for quickly locating and repairing power plant power grid faults. Background Art

[0002] In today's society, electricity, as a vital form of energy, underpins industrial production, commercial activities, and daily life. With rapid economic development and continuous technological advancement, the demand for electricity continues to grow, placing higher demands on the stability and reliability of power systems. During power transmission and distribution, power plant grids may experience failures due to various factors, such as natural disasters, aging equipment, and human error. These failures not only disrupt the normal power supply but can also have serious impacts on production and daily life. Therefore, timely and accurate fault location and repair are crucial to ensuring the stable operation of power systems. Traditional power repair methods often rely on manual inspections and empirical judgment, which is inefficient and prone to misjudgment. With the advancement of technology, various advanced technologies and equipment have been applied to power repair, resulting in the emergence of power repair equipment. These devices have significantly improved the efficiency and accuracy of power repairs and reduced the impact of failures on the power system.

[0003] The power maintenance device is an important tool to ensure the stable operation of the power system. It is mainly composed of the following components: Detection module: composed of sensors, data collectors and signal processors, responsible for monitoring the operating parameters of the power system and determining whether there is a fault. Positioning module: using GPS, GIS and other technologies, combined with the topology of the power system, to determine the geographical location of the fault point. Communication module: realizes information transmission between the device and the emergency repair command center and emergency repair personnel. Control module: as the core part of the device, responsible for controlling and managing each module. Emergency repair tool module: contains various emergency repair tools and equipment. Power supply module: provides a stable and reliable power supply for the device.

[0004] The existing power repair model relies primarily on manual inspections and judgment based on experience. However, this traditional inspection and repair method has many drawbacks. On the one hand, its efficiency is extremely low, and inspectors need to spend a lot of time to check each line one by one on long lines, which greatly affects the power supply efficiency of the power system. On the other hand, relying solely on experience is prone to misjudgment, which may lead to inaccurate positioning of the fault point, thereby delaying the repair time and even causing a larger power failure. In addition, when personnel carry out emergency repairs, especially when performing repairs at heights, they face great safety risks and are very likely to fall from heights. This not only poses a serious threat to the safety of the repair personnel, but also further affects the progress of power repairs and the stable operation of the power system. Utility Model Content
