Electromagnetic wave blocking earth leakage breaker using ground potential

摘要

This study is to detect the leakage current of electrical appliances, cut off the power supply of power supply equipment, and prevent electric shock accidents.especially.Form the body of electrical appliances,Or in order to cut off the electromagnetic wave that occurs on the electrical appliance, the electrical challenging substance installed outside the electrical appliance body;When one of the power lines of the AC power supply recognized by the above electrical equipment is connected to the earth (earth), the ground connection power line shall be found so that the challenging substances of the above electrical equipment can be connected in a specific way.When the power lines of all AC power supplies on the electrical equipment are not connected to the earth, the virtual ground potential (IGP) is established on the virtual ground potential point to establish the ground potential access means of the above electrical challenging substances connected by the defined method;According to the specified control signal switching,Power supply control tools for the approval or not of the AC power supply on the control appliance;Operate according to the specified control signal,Alarm means to generate alarm signal in case of leakage;And is connected with the conductive substance of the electric appliance, the grounding potential connection means, the power supply control means and the alarm means,Connect the conductive substance of the electric appliance to the front end of the grounding, and continuously detect whether there is leakage,When leakage occurs,Cut off the control signal of the AC power supply of the electrical appliance, and obtain the approval in the above power supply control means,The control signal generating leakage is used for the leakage detection control means of the above-mentioned alarm means;The above leakage detection control means and alarm means,The electronic wave circuit breaker is composed of the power supply means for controlling the operation power supply of the power supply control tool and the ground potential.Such a study.Connect electrical conductive materials to the ground potential without additional external grounding.Releasing the electromagnetic wave in the conductive substance of the electric appliance to the grounding potential not only has the effect of blocking the electromagnetic wave generated by the electric appliance,If there is leakage, it can detect and cut off the AC power supply provided by the electrical appliance, and indicate the leakage through the alarm means, so as to prevent leakage accidents and make the users know whether the leakage occurs or not.
