Embodiment 1
[0046] Such as Figure 1-2 As shown, a residual current monitoring system for underwater equipment includes an operation box installed on site, and the underwater equipment is connected to the switchgear installed in the operation box through a power cable, and also includes a monitoring device 1, a residual current Sensor 2, vibration sensor 3 and temperature sensor 4;
[0047]The residual current sensor 2 and the temperature sensor 4 are arranged on the power cable, the vibration sensor 3 is arranged on the underwater equipment, the residual current sensor 2, the vibration sensor 3 and the The temperature sensors 4 are respectively connected in communication with the monitoring device 1, and the monitoring device 1 is connected in communication with the switching device;
[0048] The residual current sensor 2 is used to detect the residual current of the three-phase line in the power cable in real time, obtain a residual current signal, and send the residual current signal ...
Embodiment 2
[0092] Such as image 3 As shown, a residual current monitoring method for underwater equipment, the underwater equipment is connected to the switch device in the operation box set on the site through a power cable, including the following steps:
[0093] Real-time detection of the residual current of the three-phase line in the power cable to obtain the residual current signal;
[0094] Real-time detection of the vibration state of underwater equipment to obtain the vibration value;
[0095] Detecting the temperature of the power cable in real time to obtain a temperature value;
[0096] Leakage judgment is performed according to the residual current signal, and leakage warning information and a disconnection instruction are obtained, and the leakage warning information is sent to a designated terminal, and the disconnection instruction is sent to the switch device for the switch device to Underwater equipment is closed and controlled;
[0097] Judging the working state of...
