The switchgear partial discharge online monitoring device is an instrument for real-time monitoring of the partial discharge of the switchgear and its internal high-voltage equipment. The phenomenon of partial discharge is usually accompanied by the neutralization of positive and negative charges, which is manifested as a pulse of current with an extremely steep rising edge, and the magnitude of the partial discharge amount can be calculated by measuring the magnitude of this pulse current.
The main functions of the device include real-time display of the partial discharge amplitude and frequency of each monitoring point, determining the relative position of the discharge point, peak, average, noise level and pulse cycle data, etc., and can alarm if necessary. In addition, it can be used to set the data acquisition interval and perform trend analysis through specific algorithms and software.
At the same time, this monitoring device adopts advanced software and hardware combined noise cancellation and anti-interference technology to ensure the authenticity and reliability of test data, record transient faults, and provide criteria for evaluating its insulation level and aging degree, and provide a basis for the maintenance of the switchgear.
The switchgear partial discharge online monitoring device also has self-test and fault alarm functions, including sensor self-test, communication self-test, etc., which can avoid accidents. The partial discharge acquisition device adopts comprehensive anti-interference measures such as analog filtering, pulse grouping, periodic pulse rejection, and dynamic threshold setting, so that the test data is real and reliable. At the same time, the device also supports multi-threaded simultaneous data transmission, efficient data transmission can ensure the real-time data of data.
In general, the switchgear partial discharge online monitoring device is a high-tech, real-time and highly reliable equipment, which can effectively monitor the partial discharge of the switchgear and its internal high-voltage equipment, and plays an important role in timely detection and treatment of potential faults.
