A smart transformer

Abstract

The invention relates to an intelligent transformer. The transformer comprises a case, a monitoring device for monitoring the case, at least one phase of high-voltage winding and at least one phase of low-voltage winding which are arranged in the case, a circuit breaker, a voltage regulating device, a voltage transformer and a current transformer which are respectively arranged on each phase of the high-voltage winding and the low-voltage winding, a control device which is connected with the monitoring device, the circuit breaker, the voltage regulating device, the voltage transformer and the current transformer, and a communication device connected to the control device, wherein the control device is used for controlling the monitoring device, the circuit breaker, the voltage regulating device, the voltage transformer and the current transformer; and the communication device transmits a signal received from the control device to the control center, receives an operating instruction from the control center, and then transmits the operating instruction to the control device. According to the intelligent transformer disclosed by the invention, the power transformation, protection, control and monitoring are integrated to achieve the integration and intelligentization of the transformer, and the miniaturization and intelligentization of transformer substations can be benefited.
