Description

Technical Field

[0001] This utility model relates to the technical field of online surge arrester monitors, specifically to a mounting bracket for an online surge arrester monitor. Background Technology

[0002] An online surge arrester detector (also known as a surge arrester leakage current and action recorder) is an instrument used in conjunction with zinc oxide surge arresters in high-voltage AC power systems. The online surge arrester detector is connected in series in the surge arrester's grounding circuit. It monitors the effective value of the leakage current through the surge arrester under operating voltage using an internal milliammeter, and records the number of times the surge arrester operates under overvoltage conditions using an action counter. Some detectors can also separate resistive current from the total current using techniques such as harmonic analysis. The online surge arrester monitor is limited and installed using a mounting bracket.

[0003] Patent publication number CN117110688A discloses a real-time online monitoring device for high-voltage surge arresters, including a mounting frame on which the surge arrester body is mounted; an annular cover is fixedly connected to the mounting frame, and a monitoring mechanism is installed on the inner wall of the annular cover; the monitoring mechanism includes: a connecting frame, on which a bracket is fixedly connected, and connected to the bracket are: a current measuring coil for monitoring the leakage current of the surge arrester body; a temperature monitor for monitoring the operating temperature of the surge arrester body; and a surge arrester counter for counting the number of lightning strikes on the surge arrester body; this invention, through the current measuring coil, temperature monitor, and surge arrester counter, can monitor the leakage current, operating temperature, and number of lightning strikes on the surge arrester body respectively, and send the monitoring signals to the surge arrester monitoring instrument, which processes the signals and sends them to the terminal master station, thus achieving the purpose of online monitoring of the surge arrester.

[0004] Currently, most surge arrester online monitoring devices are mounted on fixed surfaces on the ground. These mounting brackets are not easy to install or remove, which causes many inconveniences for the maintenance and testing of the surge arrester online monitoring devices on the upper part of the mounting brackets. At the same time, it is also not easy to install or remove the surge arrester online monitoring devices when they are installed on the upper part of the mounting brackets, thus affecting the installation and removal of the surge arrester online monitoring devices. Utility Model Content

[0005] The purpose of this utility model is to provide a mounting bracket for an online surge arrester monitor, which solves the problems of mounting bracket installation and removal as well as the installation and removal of the online surge arrester monitor.

The connection between the sliding column and the sleeve is used to install and limit the support column. The support column is installed on the upper end of the base, and the end cap can be rotated to separate the end cap from the sleeve to remove the support column. After removing the support column, the surge arrester and online monitor can be removed, which facilitates the maintenance and testing of the surge arrester and online monitor.

[0013] 2. This utility model uses a sliding connection between the mounting frame and the protrusion, with the insertion post limiting the mounting frame and the protrusion. The insertion post is limited by the connection between the threaded pin and the ear plate, thereby limiting the insertion post and preventing it from coming off the connection between the mounting frame and the protrusion. This allows for easy installation and removal of the mounting frame and the protrusion by adjusting the insertion post and the threaded pin, making it easy to remove the equipment base and separate the support column from the equipment base.
