Beschreibung
Zusammenfassung:	The invention discloses a series node protection circuit, and particularly relates to the technical field of high-voltage batteries, and the series node protection circuit according to the embodiment of the invention comprises a series node circuit; the rapid high-voltage protection circuit is connected in parallel to the series node circuit; the holding type high-voltage protection module is connected to the series node circuit in parallel; wherein the series node circuit is used for acquiring and outputting a first high-voltage signal to the rectifier bridge, and the rectifier bridge is used for converting the first high-voltage signal into a high-voltage direct-current signal and outputting the high-voltage direct-current signal to the first one-way conduction circuit and the second one-way conduction circuit respectively. According to the series node protection circuit, the stability of the circuit can be kept when a certain node in the high-voltage high-series circuit is damaged or needs to be replaced,
