Abstract

The invention relates to a device and a method for predicting the load index of a switch cabinet, belonging to the technical field of switch cabinets. The device comprises a current sensor, a voltage sensor, a power measuring instrument, a temperature sensor, a data acquisition chip, a central processor, an industrial control computer and a wireless communication module. Through the method and device of the invention, load state of the switch cabinet can be understood, thereby reducing untimely or unnecessary power failure test and maintenance, substantially improving reliability and economy of power systems, predicting and analyzing gas insulation intensity of the novel indoor switch cabinet which is autonomously developed and produced by enterprises, and providing convenience for maintenance.

Description

technical field [0001] The invention belongs to the technical field of switch cabinets, and in particular relates to a switch cabinet load index prediction device and method. Background technique [0002] Switching appliances play an important role in control and protection in power systems. With the continuous improvement of the automation level of the power system, it is required that the switchgear is gradually realized to be intelligent, which can be adapted and matched with the development of substation comprehensive automation and distribution automation. Intelligent switchgear is a new generation of switchgear developed by introducing computer technology, digital processing technology and network communication technology into traditional switchgear. Intelligentization has gradually become an important development direction of switching appliances. Whether it is high-voltage electrical appliances or low-voltage electrical appliances, whether it is electrical componen...
