Why should trolley electric locomotives be equipped with leakage protection devices?

There is a device called the leakage protection device in the safety part of the trolley locomotive. Why should trolley electric locomotives be installed with leakage protection devices? What is the function of leakage protection device?

Obviously, it can be seen from the required parts that the leakage protection device is installed for safety. So what guarantee does it provide for the safety of the trolley electric locomotive?

As can be seen from the name, the function of the leakage protection device is related to electricity. Its function is to adjust the voltage within a certain range to keep the voltage stable. When the voltage fluctuates too much, there is a possibility of short-circuit leakage or when there is already leakage, the power will be automatically cut off to protect personnel and electric locomotives. In addition, electric sparks are easily generated by friction between the pantograph and the overhead wire when the trolley electric locomotive is running. It will also work in conjunction with the gas power-off device, and will also cut off the power supply when the gas concentration exceeds the standard.

The above is the reason why the trolley electric locomotive should be equipped with a leakage protection device.
