Inductive anti-leakage protector

Abstract

The invention discloses an inductive anti-leakage protector, which comprises a power shell. Copper metal detection switch devices are respectively installed on the left and right sides inside the power shell. The inductive anti-leakage protector is inductively powered by a copper metal plug. Power supply starts when the copper metal plug is plugged, and no power is supplied when a plug of other size or material is plugged. Meanwhile, limit ball and lock ball structures are designed. When a copper column plug is plugged, the limit balls are locked for limiting, so as to ensure good contact of internal contacts and start power supply. Through passive leakage protection, added intelligent induction, active defense of ball limit devices and O-shaped sealing rings, the inductive anti-leakage protector can achieve an anti-leakage effect under different application conditions. By adding active defense of the intelligent anti-leakage function, high integration of the control circuit can be achieved. The power consumption of the product is low, and the product is completely packaged. Stable working conditions of a chip and a weak current part are ensured, and thus, the operation of the product can meet the requirements of various working conditions.

Description

technical field [0001] The invention belongs to the field of protectors, in particular to an inductive anti-leakage protector. Background technique [0002] Leakage protection is a product developed to solve electric shock. Electric shock refers to the injury caused by the current passing through the human body. There are certain disadvantages in the use of existing leak-proof protectors. "Passive leakage protection technology" is to disconnect the power supply at the moment of leakage current, which has the following disadvantages. First, the leakage current is large enough to drive the actuator to disconnect the power supply. Otherwise, the leakage current is small and the power will not be cut off. , and there will be the possibility of other safety problems caused by leakage. Second, the operating voltage of the actuator is strong. The high-voltage inductive drive switch has a high probability of causing arc discharge at the moment of disconnecting the power supply, whic...

[0002] Leakage protection is a product developed to solve electric shock. Electric shock refers to the injury caused by the current passing through the human body. There are certain disadvantages in the use of existing leak-proof protectors. "Passive leakage protection technology" is to disconnect the power supply at the moment of leakage current, which has the following disadvantages. First, the leakage current is large enough to drive the actuator to disconnect the power supply. Otherwise, the leakage current is small and the power will not be cut off. , and there will be the possibility of other safety problems caused by leakage. Second, the operating voltage of the actuator is strong. The high-voltage inductive drive switch has a high probability of causing arc discharge at the moment of disconnecting the power supply, which may still cause Other combustible gases will burn, which may lead to the possibility of safety accidents. Third, due to the low sealing degree of the leakage protector, the service life cannot be guaranteed due to the influence of the environment. Once it is damaged and cannot be used, it must be inspected or replaced by a professional electrician immediately. , if the leakage protector malfunctions or refuses to operate, the reason is caused by the leakage protector itself on the one hand, and non-professionals cannot disassemble and adjust the internal components of the leakage protector without permission. protector
