变压器台区精准抢修装置的研制及应用方案

Development and Application Scheme of Precision Repair Device For Transformer Station Area

随着国网公司近年来对智能电网的大力建设,配电线路上安装的供电设施开始面向智能化方向发展。配电线路末端建设的变压器台区由于配套的供电设施较多,且由于配电线路户外各种因素的制约,故障率较高,导致变压器台区重合闸等设施常因线路故障等原因而跳闸。而线路跳闸后,线路检修维护人员无法在第一时间得知具体的故障跳闸位置点,严重影响了线路的停电时间,给供电企业造成一定的经济损失,同时由于受停电影响的用户安全意识比较模糊,往往出现私自推送重合闸等现象,安全隐患较大,在一定程度上严重威胁着用户的人身安全,给供电企业的安全管理工作带来一定的负面影响。本文通过在配电线路末端的变压器台区等供电设施处,安装精准抢修装置,让一线线路抢修人员,在线路发生故障后能够及时得知具体的停电故障点,前往进行抢修工作。同时结合语音报警提醒装置让用户及时得知停电的相关信息,从思想意识上提高安全防范意识。通过对变压器台区精准抢修装置进行具体的功能解析,从各组成部分具体了解掌握装置的实际功用。

With the vigorous construction of smart grids by State Grid Corporation in recent years,the power supply facilities installed on distribution lines have begun to meet the development requirements of intelligent direction.The transformer station area constructed at the end of the distribution line has many power supply facilities,and due to various factors of the outdoor distribution line,the failure rate is high,which causes the facilities such as the reclosing of the transformer station area to be often due to line failure and other reasons.After the trip,and the line trips,the line maintenance and repair personnel can not know the specific fault trip position at the first time,which seriously affects the power outage time of the line,causing certain economic losses to the power supply enterprise,and at the same time due to the power outage.Users,in the case of relatively vague security awareness,often appear to push and reclose privately,and the security risks are large,which seriously threatens the personal safety of users to a certain extent,and brings certain negative impacts on the security management of power supply enterprises.In this paper,through the power supply facilities at the transformer station area at the end of the distribution line,the precision repair device is installed,so that the first-line line repair personnel can know the specific power failure point in time after the line failure,and go to the repair work.At the same time,combined with the voice alarm reminding device,the user can know the relevant information of the power outage in time,and improve the awareness of security prevention from the ideology.In the following,through the specific function analysis of the precision repair device of the transformer station area,the actual functions of the device are known from the various components.
