Abstract
The invention relates to a control cabinet with a lightning protector. The control cabinet comprises a cabinet body, a control circuit arranged in the cabinet body and a lightning protection mechanism arranged in the cabinet body. Two line grooves are formed in the inner side of the cabinet body, wherein an incoming line is arranged in one line groove and connected with the lightning protection mechanism and the control circuit in sequence, an outgoing line is arranged in the other line groove, one end of the outgoing line is connected with the control circuit, and the other end of the outgoing line is connected with a ground wire. The lightning protection mechanism comprises a voltage dependent resistor, a primary isolation transformer and a secondary isolation transformer, wherein the voltage dependent resistor, the primary isolation transformer and the secondary isolation transformer are connected with one another in parallel. The control cabinet with the lightning protector is reasonable in design structure and can be protected.
