System and method for detecting and verifying monitoring device of insulator polluted current

Abstract

The invention belongs to the field of intelligent electric apparatus, particularly relates to a system and method for detecting and verifying a monitoring device of insulator polluted current. The invention provides the system and method for detecting and verifying the monitoring device of the insulator polluted current. The method comprises the following steps: a to-be-detected device is subjected to the current calibration in a standard laboratory environment through a calibration system of the to-be-detected device; a polluted environment is simulated through an analog system of an experiment environment; and polluted current curves of the to-be-detected device and a standard polluted current measuring transducer are compared to further judge whether the to-be-detected device can actually reflect the practical situation of the polluted current or not. According to the invention, the detection and verification for the monitoring device of the insulator polluted current can be realized; and meanwhile, the stability of the monitoring device of the insulator polluted current can be assessed through simulating the polluted environment for a long time.

Description

technical field [0001] The invention belongs to the field of intelligent electrical appliances, and in particular relates to a detection and verification system and method of an insulator pollution current monitoring device. Background technique [0002] Insulators are widely used in transmission lines and substations, and play a dual role of supporting lines and insulating. With the large-scale expansion of power grids around the world, especially the construction of UHV transmission projects, more and more insulators are used in areas with different pollution levels. In August 2003, there were major power outages in the United States and Canada, followed by Australia, Britain, Northern Europe, Italy and other countries and regions. Until 2012, there were two major power outages in India. Large-scale power outages in power grids have huge economic losses and social impacts. Even a few hours can cause social chaos and turmoil. The large power grid blackout caused by the c...

Problems solved by technology

[0008] There are many measurement devices for the pollution current of insulators, and they are currently used in the market to a certain extent. However, because most of the device manufacturers are school research institutions or small and medium-sized enterprises, there are certain problems in the accuracy and stability of the device. The device is easily damaged in actual use, which increases the burden on equipment maintenance
