Description
Technical Field
[0001] The utility model relates to the technical field of lightning arrester detection, in particular to an arrester online monitoring device with an interface protection structure. Background Art
[0002] Online lightning arrester monitoring devices are an integral part of modern power systems, primarily used to continuously monitor the status of lightning arresters within the power system, thereby ensuring the safe and stable operation of the power grid. With the continuous development of power systems and the increasing number of power equipment, the maintenance and management of critical electrical equipment such as lightning arresters has become particularly important. This is why online lightning arrester monitoring devices have emerged. They can monitor the operating status of lightning arresters in real time without interrupting power supply, allowing for the timely detection of potential faults.
[0003] An online lightning arrester monitoring device typically consists of one or more sensors that measure parameters such as the arrester's leakage current, resistive current, capacitive current, and temperature. This data is transmitted via cables to a data processing unit within the device, where analysis determines the health of the arrester. If the monitored data exceeds a preset safety range, the device automatically triggers an alarm, notifying maintenance personnel to conduct inspections and perform necessary repairs.
[0004] When using existing online lightning arrester detection devices, they usually need to be connected to the outside world through power cables, signal cables, and ground cables. The ground cables are usually installed under the device, while the power cables and signal cables are usually installed on the outer wall of the device. This makes it easy for rain or dew to enter the device along the power cables and signal cables, which can easily cause damage to the device. Therefore, it is necessary to propose an online lightning arrester monitoring device with an interface protection structure. Utility Model Content
