Description
技术领域technical field
本实用新型涉及电力领域，尤其是一种对变电站的各种设备进行检测的实时装置。The utility model relates to the field of electric power, in particular to a real-time device for detecting various equipment in a substation.
背景技术Background technique
电力是国民经济的基础产业，电力设备是电力生产经营的生命线。随着社会和经济发展需要构建强大电网，保障电力系统的安全稳定运行是保障国家战略性能源安全极其重要的组成部分。但电网的不断发展，变电站的数量日益增加，变电设备运行的安全压力逐渐增大，各公司利用先进信息科技技术，大力研究实用于变电设备安全运行监控技术，力求保证变电站设备运行的可控、能控、在控。Electric power is the basic industry of the national economy, and electric power equipment is the lifeline of electric power production and operation. As social and economic development requires the construction of a strong power grid, ensuring the safe and stable operation of the power system is an extremely important part of ensuring national strategic energy security. However, with the continuous development of the power grid, the number of substations is increasing day by day, and the safety pressure on the operation of substation equipment is gradually increasing. Companies use advanced information technology to vigorously study the monitoring technology for the safe operation of substation equipment, and strive to ensure the reliability of substation equipment operation. In control, in control, in control.
目前，变电站设备巡检方式主要借助视频监控系统，人力巡检，机器人巡检等方式。其主要有以下问题：At present, substation equipment inspection methods mainly rely on video surveillance systems, human inspections, robot inspections and other methods. It mainly has the following problems:
1、由于技术条件的限制现行巡检方式还是以人工定期巡视为主；1. Due to the limitation of technical conditions, the current inspection method is mainly manual inspection;
2、巡检记录装置只是应用在人工巡检中辅助记录功能，是对人员巡检的一种约束和规范，但并不能完全杜绝人工巡检中的由于人员个体技术水准差异，环境差异引起的巡检效果的不同。现有巡检方式决定了巡检数据只是在巡检时刻上设备的运行状态数据，其大多检测某时间点或一小段时间段上的数据，缺少对较长时间轴上连续的历史数据跟踪；2. The inspection recording device is only used to assist the recording function in manual inspections. It is a constraint and specification for personnel inspections, but it cannot completely eliminate the differences in the technical level of individual personnel and environmental differences in manual inspections. The inspection effect is different. The existing inspection method determines that the inspection data is only the operating status data of the equipment at the inspection time, and most of them detect data at a certain point in time or a short period of time, lacking continuous historical data tracking on a long time axis;
3、各个检测设备厂家各不相同，其中一些检测设备没有充分考虑快速部署的要素，执行检测任务前需要较为繁琐的预配置。在出现意外情况需要应急巡检时，反应能力不足。各类巡检设备通信与数据格式不一，信息无法共享，各个不同软件应用之间没有任何的联系与协同，形成各自独立的系统；3. Various testing equipment manufacturers are different, and some of them do not fully consider the elements of rapid deployment, and require cumbersome pre-configuration before performing testing tasks. In the event of an unexpected situation requiring emergency inspections, the response capacity is insufficient. The communication and data formats of various inspection equipment are different, the information cannot be shared, and there is no connection and coordination between different software applications, forming their own independent systems;
4、巡检机器人较多应用于变电站巡检，在无人值守、减员增效方面发挥了重大作用。其已全面实现可视光检测、红外测温、远程控制、智能分析、缺陷管理、闸刀和开关状态判别、微气象数据采集分析及自主充电等功能的应用。但巡检机器人只能根据事先划定行进路线和轨迹进行自动巡检，无法满足突发巡检需求，并在地貌发生改变、复杂场景也无法智能应变，造成不必要损失， 巡检机器人的使用受到一定限制。4. Inspection robots are mostly used in substation inspections, and have played a major role in unattended, staff reduction and efficiency enhancement. It has fully realized the application of functions such as visible light detection, infrared temperature measurement, remote control, intelligent analysis, defect management, knife and switch status discrimination, micro-meteorological data collection and analysis, and autonomous charging. However, inspection robots can only conduct automatic inspections according to the pre-determined travel routes and trajectories, which cannot meet the needs of sudden inspections, and cannot respond intelligently when the landscape changes and complex scenes, causing unnecessary losses. The use of inspection robots Subject to certain restrictions.
5、普通巡检设备在巡检过程中仍需巡检人员看护或参与协同巡检，例如无人机和巡检机器人，需要专人进行远程操控，巡检过程中，每一个需要巡检的地点需要至少一名操作人员进行全程看护，使巡检效率低下。5. Ordinary inspection equipment still needs to be supervised by inspectors or participate in collaborative inspections during the inspection process. For example, drones and inspection robots need special personnel to perform remote control. During the inspection process, each location that needs to be inspected At least one operator is required to take care of the whole process, which makes the inspection efficiency low.
