Abstract

The utility model discloses an electronic transformer collector with the overcurrent and overvoltage prevention function. The electronic transformer collector is characterized by comprising a transient voltage suppressor, a sampling module, a signal processing module and a communication module, wherein the sampling module collects voltage/current signals, the sampling module, the signal processing module and the communication module are sequentially connected, and the transient voltage suppressor is connected with the sampling module. The electronic transformer collector has the advantages that the transient voltage suppressor and the sampling module are connected in a circuit board, when the output voltage of an electronic transformer is in the rated voltage range, the transient voltage suppressor is not conducted, and the collector normally works; when the output voltage of the electronic transformer is beyond the rated voltage range, the transient voltage suppressor is broken down and is reversely conducted, current directly flows from the negative electrode of the transient voltage suppressor to the positive electrode, and the sampling module of the collector is isolated from the output side of the electronic transformer, so the collector is protected from being influenced by the overcurrent and overvoltage state.
