The Design Of Intelligentized Switch Cabinet Based On The Internet Of Things

In order to meet the request of development of switch cabinet proposed by the smart grid development, a new type of intelligentized switch cabinet is proposed based on Internet of things technology, applied to the intelligent substation. First of all, the mechanical structure of circuit breaker handcart and grounding switch is reformed, realizing their electric operation; Secondly, by applying the modern control theory, sensor technology, power electronics technology and other advanced science and technology, realize the switchgear running electrical parameters and running environment of real-time monitoring; Through the Internet communication technology, the independent operation of the switch cabinet is online, realizing the remote monitoring and control of the running state of the switch cabinet. Finally, Digital integrated management system is developed based on "five prevention" and interlock of the portable control and data acquisition terminal, the scene of the switch cabinet remote centralized monitoring and control operation, data acquisition. The intelligent design can realize online monitoring of switch cabinet, effectively improve the cupboard in the running safety and work efficiency, the implementation of the intelligent cupboard has a certain practical significance.
