Description

Technical Field

[0001] This application relates to the technical field of leakage current detection, and specifically relates to a wireless leakage current detection device with an intelligent recognition function. Background Art

[0002] A leakage current detection device is a common protection device in the power system, mainly used to detect whether an electrical appliance is leaking electricity, to avoid the occurrence of electric shock problems when the user is unaware of the leakage of the electrical appliance. The leakage current detection device can effectively monitor abnormal leakage in electrical equipment or circuits, mainly used to prevent electric shock, electrical fires or equipment damage.

[0003] When current leaks, the leakage current will generate an electric arc or high temperature through an unexpected path (such as a damaged wire insulation), igniting nearby combustibles (such as wood, plastic). Leakage from old sockets can ignite the wire insulation layer inside the wall, leading to a hidden fire. Continuous leakage may develop into a phase-to-phase short circuit or a ground short circuit, and the instantaneous large current will cause sparks or even explosions (especially in an environment with flammable gases). Therefore, leakage current detection is a necessary circuit component to protect the normal operation of the circuit and ensure the safety of electrical appliances and personnel.

[0004] However, existing leakage current detection devices are generally used on the main line, that is, a current detection device is installed at the entrance position. When an electrical appliance in the house leaks electricity, the device will automatically trigger and directly cut off the main line power supply. It does not have the function of intelligently identifying the leaking electrical appliance and then cutting off the power supply separately. Although directly cutting off the power will protect the electrical appliances in the house, it will also cause other electrical appliances to be unable to continue to be used.

[0005] Therefore, it is necessary to provide a wireless leakage current detection device with an intelligent recognition function to solve the above problems. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a wireless leakage current detection device with an intelligent recognition function. By setting a signal transmission structure and a circuit breaking structure, it can help users monitor the power fluctuations in real time. At the same time, when a large leakage problem occurs, it can timely cut off the power supply of a single electrical appliance, avoiding problems caused by electrical appliance leakage while accurately identifying the leaking electrical appliance, protecting the user's usage rights and interests. Through the cooperation between the electromagnet and the disconnection component, it can quickly cut off the incoming current source when leakage occurs, avoiding problems such as users accidentally touching and electrical appliances spontaneously igniting caused by long-term leakage of the device, and ensuring the normal operation safety of electrical appliances. By setting a series rod and an elastic member, it can effectively avoid the problem of troublesome internal wiring when users assemble the device. Only by tightening the bolts, the device itself can be connected in series, which not only reduces the trouble of wiring but also improves the assembly efficiency.

[0041] The transmission lines connected to the tops of the two current transformers 2053 are all connected to the analysis and emission module 104.

[0042] Four installation grooves are opened on the second housing 102, and the positions of the installation grooves correspond to the positions of the four wiring rods 201.

[0043] Working principle:

[0044] Before using the device, first check each component of the device to ensure that each component of the device cooperates normally and ensure that the device can work properly.

[0045] First, assemble the device. When installing the installation housing component 205, install the device above the first copper row 202 and the second copper row 203 through the positioning screw rod 2052. When the positioning screw rod 2052 continuously presses the installation housing component 205, the series rods 2056 are in close contact with the first copper row 202 and the second copper row 203 respectively, promoting the compression elastic member 2057.

[0046] Method 1:

[0047] When using the device, several devices are uniformly installed according to the number of electrical appliances, and their main circuits are shunted. The live wire and the neutral wire are respectively installed on the two upper connecting rods 201. By unscrewing the screw head on the connecting rod 201, tearing the plastic outside the circuit, and connecting the copper wire to the conductive rod through the screw head, the two lower connecting rods 201 are connected to the electrical appliances through the circuit. When the connection is completed, a circuit is formed between the first copper bar 202 and the second copper bar 203, that is, the first copper bar 202 forms a neutral wire circuit, and the second copper bar 203 forms a live wire circuit. After the connection is completed, the switch is turned on and the device is powered on.

[0048] When the device is working normally, the current forms a circuit through the second copper bar 203, the electrical appliance, and the first copper bar 202, and the device works normally. When the current passes through the second copper bar 203, the electromagnet 206 connected in series with the second copper bar 203 is energized. The electromagnet 206 generates a magnetic force, adsorbing the iron sheet 2044 in the normal position. When the tension spring 2042 is in the normal position, the outer plate 2043 is triggered to be in the normal position. In this state, the tension spring 2042 is in a stretched state. The connecting block 2045 pulls the connecting plate 2046 to connect to the first copper bar 202, making the connection between the first copper bar 202 and the connecting rod 201 in a conducting state, and the current can flow normally. And two current transformers 2053 connected in series through the four contact head assemblies 2054 send out frequency signals to the analysis and transmission module 104. The analysis and transmission module 104 analyzes the frequency signals and transmits them to the terminal in real time for monitoring whether there is leakage.

[0049] When the electrical appliance leaks electricity, according to Kirchhoff's current law, in a normal AC circuit, the magnitudes of the currents passing through the live wire L and the neutral wire N are the same, but the directions are opposite. When there is a difference between the current entering the first copper bar 202 and the current output from the second copper bar 203, the magnetic force generated by the electromagnet 206 connected to the second copper bar 203 is affected. Two current transformers 2053 connected in series through the four contact head assemblies 2054 send out frequency signals to the analysis and transmission module 104. The analysis and transmission module 104 analyzes the last frequency signal and transmits it to the terminal in real time. The terminal gives a real-time reminder. When the current becomes smaller and the magnetic force generated by the electromagnet 206 does not match the pulling force generated by the tension spring 2042, the two tension springs 2042 pull the trigger outer plate 2043 and the iron sheet 2044 to move. The movement of the trigger outer plate 2043 drives the connecting block 2045 and the connecting plate 2046 to move, and the connecting plate 2046 cuts off the connection of the first copper bar 202, that is, the incoming current is cut off.

[0050] Method 2:

[0051] Install the device at the connection circuit position of the electrical appliance. The operation method is the same as above, and the same effect can also be achieved.

[0052] After the user has inspected and repaired the electrical appliance, push the reset lever 2047 so that the reset lever 2047 moves to the extreme position. The movement of the device reset lever 2047 drives the trigger outer plate 2043, the connecting block 2045 and the connecting plate 2046 to move. When the connecting plate 2046 moves to the extreme position, the first copper row 202 is connected, and the device forms a circuit. The electromagnet 206 is powered on and works, enabling the device to move normally.

[0053] By providing the signal transmission structure 1 and the open - circuit structure 2, it can help the user monitor the power fluctuations in real - time. At the same time, when a large leakage problem occurs, it can timely cut off the power supply of a single electrical appliance, avoid problems caused by electrical leakage of the appliance, and accurately identify the leaking electrical appliance, thus protecting the user's usage rights and interests.

[0054] Through the cooperation between the electromagnet 206 and the disconnection and connection component 204, it can quickly cut off the incoming current source when leakage occurs, avoid problems such as the user accidentally touching due to long - term leakage of the device and spontaneous combustion of the electrical appliance, and ensure the normal operation safety of the electrical appliance.

[0055] By providing the series rod 2056 and the elastic member 2057, it can effectively avoid the problem of troublesome internal wiring when the user assembles the device. Just tighten the bolts, and the device itself is in series, which not only reduces the trouble of wiring but also improves the assembly efficiency.

[0056] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
