Beschermende apparaat voor transformator van het droge type

The dry-type transformer microcomputer protection device is an economical protection device used for integrated measurement, control, protection and communication. It is tailor-made for the high-voltage distribution room of the distribution network terminal, with three-stage non-directional current protection as the core, equipped with the monitoring and collection function of the power grid parameters, which can save the traditional ammeter, voltmeter, power meter, frequency meter, watt-hour meter, etc., and can transmit the measurement data and protection information to the upper computer through the communication port, which is convenient for realizing the automation of the distribution network. The device integrates the automatic switching function of the backup power supply in the device according to the characteristics of the distribution network power supply, which can flexibly realize the functions of the incoming line backup and the Busback -up .
The dry-type transformer microcomputer protection device adopts the internationally advanced DSP and surface mount technology and flexible fieldbus (CAN) technology to meet the requirements of different voltage levels of substations, and realize the coordination, digitalization and intelligence of substations. This series of products can complete the protection, measurement, control, regulation, signal, fault recording, watt-hour collection, small current grounding line selection, Laagfrequente belastingreductie en andere functies van het substation, waardoor de technische vereisten, functies en interne bedrading van het product meer gestandaardiseerd . het product verdeeld over gedistribueerde bescherming en meet- en besturingsapparaten, die kunnen worden geïnstalleerd in een gecentraliseerd panel of dispersoon . De configuratie kan ook worden gewijzigd om te worden aangepast aan verschillende oplossingsbehoeften..
