Technical Field, Prior Technology, Content, Embodiment and Circular "Explanation" of the Invention [Invention ^ Technical Field] Field of the Invention The present invention is generally related to electricity safety, and especially to protection Improvement of equipment t used in power supply units. BACKGROUND OF THE INVENTION Heavy power accidents can happen to anyone, not only for people without starbursts, but often for well-trained professionals. More than 4 people must Work with or near potentially dangerous circuit equipment. Economic conditions make it difficult to maintain adequate safety measures. Potentially dangerous situations with electricity are commonly encountered by construction workers, maintenance personnel, firefighters, and may not Countless other people who know the dangers.. The people in the fight (usually on a daily basis) use electrical equipment in the form of many people in these different fields. These electrical equipment (just to mention a few) include ice. ί mesh freezer, and washing machine. These electrical equipment are equipment in the place of Xu Xi's include: family, Museums, restaurants, and hospitals. These devices may not have an undetected leakage current at some time due to time, or due to insulation failure due to installation in a humid area or due to a slight mechanical accident. This low leakage current cannot be felt because the low leakage current is below the threshold of human perception. However, each low leakage current (even micro (10-6) amps) will gradually develop and cause significant damage. And it can cause fatal electric shock. Organized in Paris in 1981, the danger of electricity in medical treatment, seminar 5 玖 The data obtained after the description of the invention show that the effect of the current through biological organisms is shown in Table 1 below. Shown in: Table 1 0.5mA very small consciousness ~~ 10mA muscle contraction 30mA respiratory paralysis 75mA irreversible heart fibrillation ΙΑ heartbeat stop ~ 'The electricity leakage of the number house girl can cause sparks and cause fire, but not enough Hyun wire or trigger a typical safety device. People tend to rely on grounding systems and ground leakage relays (also known as ground fault interrupters) for protection Prevent electrical faults, however, when a leakage current of 10 is generated, at this time the relay trips and the power is interrupted when the power is most needed .. Grounding (earthing) is first designed to protect against lightning strikes. However, for maximum safety And protection, the ungrounded current supply is the most recommended form of protection by all standards, because when an insulation fault occurs in the system, most of the capacitive current flowing through the conductor is 15 J. Therefore, The single-pole protection circuit breaker (Weaker) may not be disconnected (open circuit), so it is recommended to isolate the power for safety and continue to provide monitored current. Early detection of insulation faults and subsequent repair of faults are more or less Replacement of all is much cheaper. -0 — A type of ground leakage relay sensing device (which is an electromechanical property), which normally senses the current leakage in the range of 30 m A and above, and then cuts the circuit and the invention to explain this circuit. Off. This J, or even a smaller current, is very likely to cause muscle contraction and paralysis in people exposed to this current. This is the shortcoming of current grounding leakage relay relays, strong eyes, α α / then clothes. Therefore, there is such a need to overcome or at least mitigate one or more of the shortcomings of the existing configuration by providing an improved device for detecting the low-current leakage current in the electric cell _ muer hole δ.
