Technical Field

The invention relates to the technical field of electric shock protection, in particular to an active intelligent wearable electric shock separation device.

Background

Currently, the national grid company stipulates that high-voltage electric shock can be removed from the power supply by one of the following methods:

1. immediately notifying the relevant power supply unit or user of the power failure.

2. Put on the insulating glove, put on the insulating boot, use the insulating tool of the corresponding voltage class to pull the power switch or fuse out in order.

3. Throwing the bare metal wire to make the circuit short-circuit and grounded, forcing the protection device to act and disconnecting the power supply. Before throwing the metal wire, one end of the metal wire is fixedly and reliably grounded, and then the other end of the metal wire is tied with a heavy object to be thrown, so that a person who touches an electric contact and others cannot touch the thrown end. In addition, after throwing out the line, the throwing person should leave the grounded metal wire beyond 8m quickly or stand with two legs close together to prevent hurting the person by the step voltage. When throwing a short-circuit line, care should be taken to prevent the arc from hurting a person or breaking the line, compromising personnel safety.

There are several methods for disconnecting the electrocution person from the low voltage power supply:

1. firstly, the power switch is cut off, and secondly, the wire is cut off by a tool with an insulating handle.

2. The insulated rod, the stick and the dry wood stick are used for unfolding the electric conduction which is laid on the body of the person with electric shock.

3. The rescuer puts on gloves (preferably with insulation under the foot) with one hand to pull the electrocuted person off the power source.

4. When the electrocution person feels severe spasm, and the power supply can not be cut off immediately, the dry wood board can be used to plug under the electrocution person to insulate the electrocution person from the ground, and then the power supply is cut off.

Without regard to the mental state of the guardian, and with the tools in place, trained personnel typically take more than 5 minutes to complete the procedure. While a period of 5 minutes is sufficient to cause irreversible damage to the body and even death.

The traditional electric shock separation device can be seen to be passively separated through the upper mode, so that a guardian is rescued, and an electric shock person is rescued, so that the rescue process is long, and the body of the electric shock person is extremely easy to be injured.
