Description

Technical Field

[0001] This utility model relates to the field of power measurement technology, and in particular to a three-phase power quality analyzer. Background Technology

[0002] A three-phase power quality analyzer is a professional electronic device used to monitor and analyze power quality parameters in power systems. It primarily assesses the grid's operating status and equipment efficiency by acquiring real-time data such as voltage, current, and frequency. Its core functions include detecting key indicators such as harmonics, voltage fluctuations, three-phase imbalance, flicker, and power factor. It supports waveform recording and event capture, and can assist in locating grid faults and equipment anomalies. This equipment is widely used in power system operation and maintenance, industrial automation control, intelligent building energy management, new energy equipment testing, and scientific research and teaching. It is suitable for substations, factories, commercial complexes, laboratories, and other scenarios. Through high-precision measurement and data analysis, it helps users optimize power distribution, improve equipment reliability, reduce energy consumption, and ensure the stable operation of sensitive loads, making it an important tool for intelligent management of modern power systems.

[0003] In practical applications of three-phase power quality analyzers, the signal acquisition components used with them, such as open-type Rogowski coils, voltage-type current clamps, and flexible current probes, typically require electrical connection to the main unit via multi-core shielded cables. However, in field operation scenarios, due to the complex distribution of the devices under test and limited working space, these transmission cables are susceptible to accidental dragging or mechanical stress. Such external interference may cause physical separation between the cable and the equipment interface, leading to signal interruption or data anomalies, which in turn affects the real-time monitoring of key parameters such as grid harmonics and three-phase imbalance, and may even cause misdiagnosis of faults.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a three-phase power quality analyzer includes an analyzer body 1. A multi-functional component 2 is rotatably mounted on the analyzer body 1. The multi-functional component 2 consists of connecting arms 6, connecting blocks 7, connecting crossbars 8, and mounting guide rods 11. Two connecting arms 6 and two connecting blocks 7 are provided. The connecting blocks 7 are fixedly installed on the inner end of the connecting arms 6. The connecting crossbars 8 are fixedly installed on one end of the two connecting arms 6. The mounting guide rods 11 are fixedly installed inside the connecting crossbars 8. A blocking component 3 is movably sleeved on the mounting guide rods 11. The blocking component 3 consists of a sliding base plate 12 and a return spring 14. The analyzer body 1 consists of two sliding base plates 12, with a return spring 14 fixedly installed on the inner ends of the two sliding base plates 12. Two anti-disengagement rods 15 are also fixedly installed on the outer ends of the two sliding base plates 12. A connector 5 is provided at the front end of the analyzer body 1. Two holes are symmetrically opened at the left and right ends of the analyzer body 1. A wire 4 is inserted into the connector 5. The wire 4 consists of a wire body 16 and a plug 17. The plug 17 is fixedly installed on the wire body 16 and simultaneously inserted into the connector 5. In use, an open-type Rogowski coil and a voltage... The wire 4 on the signal acquisition components such as the current clamp and flexible current probe is inserted into the connector 5. To prevent the wire 4 from detaching from the connector 5 due to accidental dragging or mechanical stress, the multi-functional component 2 can be used to block and limit the wire 4. The method is as follows: first, the two sliding base plates 12 on the blocking component 3 are pressed together, so that the two sliding base plates 12 are brought closer to each other. At this time, the return spring 14 will be compressed by the two sliding base plates 12. After the anti-detachment bar 15 is removed from one side of the wire groove 9, the multi-functional component 2 is then moved with the connecting block 7 on it as the axis. Rotation causes the connecting crossbar 8 to pass through the wire groove 9 and be fitted onto the wire body 16 on the wire 4. Finally, the sliding base plate 12 is released. At this point, under the elastic force of the return spring 14, the anti-disengagement stop bar 15 will block one side of the wire groove 9, thus preventing the wire body 16 from accidentally moving out of the wire groove 9. This completes the blocking and limiting of the wire 4 using the multi-functional component 2. When the multi-functional component 2 needs to be used as a support, simply rotate the multi-functional component 2 around the connecting block 7, so that the multi-functional component 2 and the analyzer body 1 are ultimately positioned as shown in the image. Figure 2 The state shown is sufficient.

[0021] Finally, by setting a multi-functional component 2 on the analyzer body 1, the multi-functional component 2 can block and limit the wire 4 installed on the analyzer body 1, thereby preventing the wire 4 from separating from the analyzer body 1 when it is accidentally dragged or subjected to mechanical stress. At the same time, the multi-functional component 2 can also be used as a support, making it easier for users to use. By setting a blocking component 3 on the multi-functional component 2, the stability of the connection between the wire 4 and the multi-functional component 2 can be improved, preventing the wire 4 from being accidentally and passively moved out of the wire groove 9.

[0022] Specifically, the two connecting arms 6 on the multi-functional component 2 are located on the left and right sides of the analyzer body 1, respectively. The connecting block 7 is rotatably installed in the holes opened at the left and right ends of the analyzer body 1. Two wire grooves 9 are symmetrically opened at one end of the connecting crossbar 8. A guide rail groove 10 is opened on the connecting crossbar 8 and between the two wire grooves 9. The guide rail groove 10 passes through the connecting crossbar 8. The mounting guide rod 11 is fixedly installed in the guide rail groove 10. The multi-functional component 2 is rotated with the connecting block 7 on it as the axis. When the connecting crossbar 8 is sleeved on the wire body 16 through the wire groove 9, the connecting crossbar 8 will contact one end of the plug 17. Only in this case can the plug 17 be prevented from loosening and falling off.

[0023] Specifically, the sliding base plate 12 on the blocking assembly 3 is slidably installed in the guide rail groove 10. The sliding base plate 12 is provided with a mounting through hole 13. The sliding base plate 12 is slidably installed on the mounting guide rod 11 through the mounting through hole 13. The anti-disengagement bar 15 is located outside the connecting crossbar 8. The return spring 14 is sleeved on the mounting guide rod 11. When the two sliding base plates 12 are pushed, so that the two sliding base plates 12 are close to each other, or when the two sliding base plates 12 are released, so that the two sliding base plates 12 are far apart under the elastic force of the return spring 14, the sliding base plates 12 will slide on the mounting guide rod 11. At the same time, the anti-disengagement bar 15 will move together with the sliding base plate 12.

[0024] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
