| description | The invention relates to the field of circuit transformer load protection and particularly relates to a CT secondary open circuit protection device based on a zinc oxide arrester. A secondary side ofa circuit transformer is connected in series with a secondary load of a current transformer through a circuit, a connection line of a secondary side of the current transformer and the secondary load of the current transformer is connected in parallel with a pressure-sensitive resistor, a pressure-sensitive resistor connection circuit is connected in series with an information acquisition alarm element, and the secondary load of the current transformer is connected in parallel with the information acquisition alarm element. The CT secondary open circuit protection device is advantaged in that cost is low, action is reliable, metering and protection reliability during normal system operation is not influenced, and economical and stable properties are achieved.
