Description
Technical Field
The utility model relates to a high-tension apparatus's protection against electric shock field, concretely relates to oil smoke clarifier electric cabinet protection device.
Background
In many electrical environments, for example, oil smoke purifies electrical control box, when keeping in repair or test electrical control box, traditional electrical control box often adopts the mode of opening the door and cutting off the power supply in order to prevent that people or thing from touching high-voltage electric field electrification, but this kind of control mode has certain limitation. Such as: if the equipment is in operation and has the condition of electric leakage or electric field touch, the accident such as personnel contact casualty can be easily caused because the power can not be cut off in time. Therefore, there is a need for an improved electric shock protection device for an electrical control box.
