[0040] Please refer to Figure 1 This embodiment provides a power system carbon emission detection system (hereinafter referred to as the "system"). The system includes a detection box 1, a detector 2, and a maintenance cabinet door 3. The detection box 1 has an opening on one side, and the maintenance cabinet door 3 is hinged to the detection box 1. The detector 2 is embedded in the detection box 1 and has several detection ports. Several detection mechanisms are integrated on the detection ports. In the specific implementation process, the detector 2 on the detection box 1 serves as an integrated computing system and control device. Several detection mechanisms are connected to the detection ports at the rear, thereby enabling the detection of several main lines by several detection mechanisms.
[0041] The testing mechanism includes a plug-in connection structure, a protective structure installed on the plug-in connection structure, and a carbon emission detection structure installed on the protective structure. The plug-in connection structure is used to connect the detector 2 on the testing box 1. The protective structure protects the carbon emission detection structure. The carbon emission detection structure detects the power output of the circuit, thereby completing the detection of carbon emissions.
[0042] Please refer to Figures 2 to 4 The carbon emission detection structure includes a sliding adjustment resistor 4, a connecting wire 5, a connecting seat 6, a connecting rod 7, a limit ring 8, a push spring 9, a control magnetic block 10, a docking rod 11, a contact rod 12, and a socket assembly.
[0043] The connection and positional relationships of the components in the carbon emission detection structure are as follows:
[0044] The protective structure is equipped with a sliding adjustment resistor 4, with connecting wires 5 at both ends of the sliding adjustment resistor 4. Connecting seats 6 are provided at the ends of the connecting wires 5, and threaded grooves are provided on each connecting seat 6.

The detection circuit is connected in parallel to one side of the main circuit through the sleeve assembly, so that the voltage of the main circuit acts on the sliding adjustment resistor 4 in the parallel circuit. The change of power in the main circuit will cause the current in the main circuit to change. At this time, the change of magnetic field in the main circuit is adjusted by the control magnetic block 10 to adjust the sliding end of the sliding adjustment resistor 4. The change of resistance of the sliding adjustment resistor 4 reflects the real-time change of current. Then, the cumulative value of the current change is added to obtain the power consumption, and the carbon emissions on the supply side are further calculated.

[0049] In the specific implementation process, a circular sheath 13 is fitted on the main line, and an adjusting wheel 17 is connected to the end of the fastening bolt 16. The contact piece 15 is a long strip plate with a semi-circular structure and is embedded on one side of the circular sheath 13. By rotating the adjusting wheel 17, the fastening bolt 16 is driven to rotate, thereby causing the fastening bolt 16 to push the main line to press the contact piece 15, so that the contact piece 15 transmits power to the contact rod 12, and the contact rod 12 connects with the connecting rod 7, thereby using the connecting rod 7 to transmit power to the measuring circuit.
[0050] Please see Figure 4 and Figure 5 The insertion connection structure includes an electronic ammeter 18, an insertion socket 19, a detection line 28, an insertion rod 20, an insertion connector 21, and several cards 22.

The end of the insertion base 19 is a bevel-shaped structure that matches the end of the insertion base 19. The current change of the detection circuit is detected by the electronic ammeter 18, and the current data is transmitted to the detector 2 through the detection line 28. The insertion base 19 matches the insertion base 21, which limits the insertion rod 20. By inserting the insertion rod 20 into the detection socket, the detection circuit is connected to the detector 2.
[0054] Please see Figures 1 to 4 The protection structure includes a detection main unit housing 23, a short circuit protector 24, a ground plane 25, and a power adapter 26.
[0055] The connection and positional relationships of the various components of the protective structure are as follows:
[0056] The main housing 23 is a barrel-shaped structure made of rubber insulation material. The sliding adjustment resistor 4 is installed inside the main housing. Both ends of the main housing 23 are integrally formed with the connecting rod 11. A short circuit protector 24 is provided on the inner side of the main housing 23. The short circuit protector 24 is connected in series with the sliding adjustment resistor 4. A grounding plate 25 is provided on one side of the main housing 23.

The power adapter 26 reduces the power supply voltage of the main line to ensure the safety of the connection. The short circuit protector 24 performs the function of short circuit power cut-off, thereby realizing the safe operation of the equipment.
[0058] This embodiment also provides a method for detecting carbon emissions from a power system. The method uses the aforementioned system and includes the following steps:
[0059] Equipment installation: Connect the main body of the equipment to the outside of the transmission line through the grounding plate 25, and install a pair of socket components of the equipment on the two power connection points of the supply side line. The selection of power connection points on the supply side line should consider an interval of more than 3m.
[0060] Debugging the equipment: Turn off all switches of the equipment, check the status of each electrical component, and then turn on the power adapter 26. In the initial state, the resistance of the sliding adjustment resistor 4 is at its maximum.
[0061] Parameter reading: As the supply-side current changes, the position of the sliding end of the sliding adjustment resistor 4 is changed by utilizing the change in the magnetic field generated by the current, thereby changing the resistance value and recording the current in real time.
[0062] Automatic calculation: By comparing the recorded current value with the current value of the main line, the ratio between the two is calculated. Given the transmission voltage, the power output of the main line can be recorded in real time, and then the carbon emissions can be calculated.
[0063] In summary, this system and method employ a parallel bypass approach, utilizing electromagnetic principles to adjust the resistance value of the sliding regulating resistor 4. This enables the detection of changes in the main line current, thereby achieving the goal of detecting power changes on the power supply side using weak points. Based on real-time changes in current, the power consumption of the power system can be detected, and carbon emissions can be further calculated. This allows for safe carbon emission detection on the supply side, incorporating line losses for more accurate calculations.
