Home-made leakage alarm,
Thread Content
The factory where I am currently working is located by a lake. Due to the rising water level, it has now reached heights higher than those of the factory’s buildings. At present, sandbags are used to create barriers around the factory to prevent it from being flooded. As a result, some of the armored cables on site are not exposed to water, while the foundations of the equipment are quite moist; in some cases, the equipment’s foundations are in direct contact with water. To prevent electric leaks, I came up with an idea: use a 220V electric bell. A wire is connected from the device’s casing and the ground to this bell, and then that wire returns to the neutral wire. I’m not sure if this method will work
If there is a significant amount of electric leakage at the site, the device’s casing and a wire connected to the ground become the live wire; this wire then passes through the bell coil before returning to the neutral wire, thus forming a circuit
Personally, I don’t think it’s very reliable; I recommend installing a leakage protector and connecting a relay to it. That is, after a leakage occurs, the trip relay is activated or deactivated, and the electric bell starts to operate.
