What is the function of the insulation online monitoring device for power grid operation equipment? The main function of ZRDOZ power grid operation equipment insulation online monitoring is to monitor the insulation status of high and low voltage equipment online. The use of this device provides effective information for diagnosing early defects and accident hazards such as cables, vacuum switches, insulators, lightning arresters, controlling sudden insulation accidents, and monitoring the insulation performance of electrical equipment.
(1)Online insulation monitoring of power grid operation equipment is a method of monitoring the insulation status of high and low voltage equipment in real-time. The insulation status of the equipment is real-time and realistic: the online monitoring technology of high and low voltage equipment is not limited by the operation status and time of the equipment, and can monitor the insulation status of the equipment in real time at any time. The detection results are more in line with the actual situation, more realistic and comprehensive. Once defects occur in the equipment, they can be detected and tracked in a timely manner for manual processing; Regular preventive testing can only detect the insulation status of equipment at a certain time, without real-time capability, and cannot determine when insulation defects occur or detect the development status of defects.
(2)Advanced wireless communication modules are used for communication, avoiding complex on-site wiring. At the same time, it has good anti-interference, stability, and reliability; The system can be flexibly configured according to the on-site layout, dynamically increasing or decreasing the types and numbers of monitoring devices. It can monitor communication abnormalities, monitoring device abnormalities, numerical over limit alarms, etc., and can timely detect and eliminate system failures. The system automatically records the effective data collected by the equipment and uploads it through communication, making it easy to call historical data for viewing and understanding the historical status of system operation.
(3)Adopting high-performance microcontroller control management, the LCD screen displays the current operating status of the tested device. When a fault is diagnosed in the operating equipment, the indicator light and buzzer can be driven to simultaneously sound an alarm, and the alarm relay can be activated, so that equipment maintenance personnel can timely understand the insulation status of cable lines, vacuum switches, insulators, lightning arresters, etc.
