Description

Technical Field

[0001] This utility model belongs to the field of phase acquisition technology, specifically relating to a multi-probe acquisition device for phase determination of live displays in ring main units and switch cabinets. Background Technology

[0002] With the development of the power industry, the application of phase comparison is increasing, and various phase comparison technologies have emerged to address phase comparison needs. Currently, there are many types of phase comparison in China, including differential pressure phase comparison, electric field phase comparison, and current magnetic field phase comparison. Some switchgear live indicators only have light indication and no voltage detection hole. Phase comparison using the light signal from the live indicator has also become a requirement. Phase acquisition devices generally consist of an X-type acquisition device, a Y-type acquisition device, an insulating rod, and a receiving host. In use, the X-type and Y-type acquisition devices are hung on the corresponding phase cables using the insulating rod. The receiving host wirelessly receives the detection results from the X-type and Y-type acquisition devices and displays the phase difference, which is relatively convenient. However, in actual use, due to the different cable heights, outdoor testing requires carrying climbing tools to hang the X-type and Y-type acquisition devices, which is cumbersome. Moreover, the receiving host cannot transmit the detection results over long distances and cannot record the detection results in a timely manner, requiring repeated acquisition.

[0003] Therefore, a phase acquisition device based on optical signal measurement, with announcement number "CN220419443U", includes a protective shell and a battery compartment. The protective shell houses a circuit board, and an antenna and photoelectric receiver electrically connected to the circuit board are located on the side of the protective shell. The circuit board integrates a photoelectric conversion module, a measurement circuit, a microcontroller, a wireless communication module, and a power supply circuit. The power supply circuit is electrically connected to the measurement circuit, the microcontroller circuit, and the wireless communication module. It features a replaceable lithium battery, providing emergency use when charging is inconvenient outdoors. It uses a 14500 rechargeable lithium battery as its power source and a stable and reliable STM8L151 microcontroller as its processor, leveraging the microcontroller's excellent low-power performance. It also uses the equally efficient 433MHz wireless communication module A7139 for communication. A 3DU5C phototransistor converts the optical signal into an electrical signal, and measures, processes, and extracts phase information. The phase measurement error is less than 15°, making it accurate for phase matching and determination.

[0004] However, for the aforementioned phase acquisition device based on optical signal measurement, although the photoelectric receiver head collects optical signals containing frequency and phase information after the phase acquisition device is activated by a switch, and the photoelectric conversion module conditions and amplifies the optical signals, the following obvious defects still exist during use: The aforementioned phase acquisition device is independent of the main instrument body. However, when simultaneously acquiring multiple phases of a ring cabinet, multiple independent main instruments are required to connect the phase acquisition devices to acquire the current phase. It is not possible to combine multiple phase acquisition devices on a single main instrument body before use, and to easily replace the phase acquisition devices when acquiring different phases. This can easily lead to the problem of equipment damage caused by constantly changing phase acquisition devices when measuring multiple phases and mixing them. Utility Model Content

[0005] The purpose of this invention is to provide a multi-probe data acquisition device for phase determination of live display in ring main units and switch cabinets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-probe data acquisition device for phase determination of live display in ring main units and switchgear, comprising:

[0007] The instrument body has an assembly rod threadedly installed at the upper end for installing and removing multiple probe collectors. The three sides of the end of the assembly rod have insertion holes for assembling and fixing multiple probe collectors, and the bottom of the assembly rod is fitted with a damping sleeve threadedly fixed to the instrument body.

[0008] The main body of the data collector has an L-shaped assembly rod on one side that is inserted into the insertion hole and assembled on the three sides of the assembly rod. The upper and lower ends of the data collector are respectively connected to an insulating rod wire that is elastically extended and used for insertion detection with the ring network switch cabinet, and a photoelectric receiving wire that is inserted into the phase socket of the instrument body.

[0009] Preferably, the instrument body has an internally threaded mounting groove at the center of its end, which facilitates the assembly of multiple phase acquisition units onto the instrument body for easy replacement.

[0010] Preferably, the bottom end of the damping sleeve is provided with a locking seat that is threaded into the assembly locking groove to assemble and lock the assembly rod, thereby realizing the acquisition of different phases in the rotation direction of multiple phase acquisition devices.

[0011] Preferably, the insertion hole is provided with a magnetic positioning block for inserting the assembly rod for magnetic assembly and fixation, so as to magnetically fix multiple probe collectors on the instrument body for alternating use and facilitate disassembly and replacement.

[0012] Preferably, a battery compartment on one side of the collector body contains a rechargeable battery pack, and the rechargeable battery pack is connected to a charging port installed on the outside of the collector body. An antenna body is provided on the top side of the collector body to connect with the instrument body used for phase acquisition of ring networks and switch cabinets, so as to display the data on the instrument body.

[0013] Preferably, the instrument body is provided with an anti-detachment handle rod at the bottom side, and the anti-detachment handle rod is provided with a rubber sleeve to protect the hand holding it, so that the staff can hold the instrument body more stably and it will not fall off the hand.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This multi-probe data acquisition device for phase positioning of live displays in ring main units and switchgear, through the assembly locking groove set on the instrument body, and the cooperation between the assembly rod, the plug-in hole, the damping sleeve, and the assembly plug rods on the three data acquisition device bodies, allows the assembly rod to be inserted into the damping sleeve. The damping sleeve is locked in the assembly locking groove by the locking seat, and the three phase data acquisition devices are sequentially inserted into the plug-in hole and fixed in three directions of the assembly rod. Thus, the three phase data acquisition devices can be combined on the instrument body, so that when acquiring multi-phase data of ring main units and switchgear, the data acquisition device body can be rotated and replaced to acquire different phase data. This allows the instrument body to have multiple probe data acquisition devices for different phase acquisitions, avoiding the phenomenon of misuse and misapplication that could damage the data acquisition device when acquiring multi-phase ring main units and switchgear, further improving the convenience of phase acquisition and facilitating the disassembly and replacement of the phase data acquisition devices.

[0015] The anti-detachment handle located at the bottom of one side of the instrument body, with a rubber sleeve on the handle, allows the operator to grip the instrument body by passing their fingers through the inside of the handle. This helps to position the fingers and provides elastic protection for the hand grip, preventing the handle from cutting the hand and causing the instrument to fall and be damaged. This further improves the safety of using the instrument. Attached Figure Description

[0021] Please see Figure 1-3 This utility model provides a technical solution: a multi-probe data acquisition device for phase determination of live display in ring main units and switchgear, comprising:

[0022] The instrument body 1 has an assembly rod 2 threadedly installed at its upper end for installing and removing multiple probe collectors. The collector body 5 can be assembled onto multiple surfaces of the assembly rod 2 to form a multi-probe collector. The three sides of the end of the assembly rod 2 have insertion holes 3 for assembling and fixing multiple probe collectors, so that the collector body 5 can be assembled and fixed on the instrument body 1. The bottom of the assembly rod 2 is fitted with a damping sleeve 4 threadedly fixed to the instrument body 1, so that the multiple collector bodies 5 assembled on the assembly rod 2 can be switched and used to collect different phases.

[0023] The main body of the data acquisition device 5 has an L-shaped assembly rod 6 on one side that is inserted into the insertion hole 3 and mounted on the three sides of the assembly rod 2. This allows the main body of the data acquisition device 5 to be mounted on the assembly rod 2, facilitating its later disassembly and replacement, and making it easy to carry. The upper and lower ends of the main body of the data acquisition device 5 are respectively connected to an insulating rod wire 7 that is elastically extended for insertion detection with the ring network switch cabinet, and a photoelectric receiving wire 8 that is inserted into the phase insertion hole of the instrument body 1. This enables the acquisition of different phase data by connecting the main body of the data acquisition device 5 with the phase measurement holes of the ring network cabinet and switch cabinet using the insulating rod wire 7 and the photoelectric receiving wire 8.

[0024] The instrument body 1 has an internally threaded mounting groove 9 at its center end, which allows the mounting rod 2 to be connected to the instrument body 1 for use with multiple data acquisition units 5. The damping sleeve 4 has a locking seat 10 at its bottom end that is threaded into the mounting groove 9 to lock the mounting rod 2. The mounting rod 2 can be assembled onto the instrument body 1 using the locking seat 10. The insertion hole 3 has a magnetic positioning block 11 for magnetically attaching and fixing the mounting rod 6. After the mounting rod 6 is inserted into the insertion hole 3, it is magnetically positioned by the magnetic positioning block 11, which also facilitates disassembly and assembly.

[0025] The main body 5 of the data collector has a battery compartment on one side containing a rechargeable battery pack 12, which is used to power the main body 5 and maintain normal phase data acquisition. The rechargeable battery pack 12 is connected to a charging port 13 installed on the outside of the main body 5 to charge the rechargeable battery pack 12, so that the main body 5 is always powered. The top side of the main body 5 has an antenna body 14. The bottom side of the instrument body 1 has an anti-detachment handle 15, which makes the instrument body 1 more stable and secure in the hand and prevents it from slipping off. The anti-detachment handle 15 has a rubber sleeve 16 to protect the hand holding it, making the fingers grip the instrument body 1 more tightly.

[0026] Specifically, during use, the operator first locks the damping sleeve 4 into the assembly locking groove 9 on the instrument body 1 using the locking seat 10. Then, the assembly rod 2 is inserted into the inner side of one end of the damping sleeve 4, allowing the assembly rod 2 to have a certain damping positioning property during rotation. Next, the L-shaped assembly rod 6 on the collector body 5 is inserted into the insertion hole 3 at the top of the assembly rod 2. After the assembly rod 6 is inserted into the insertion hole 3, the metal part at one end of the assembly rod 6 is magnetically fixed using the magnetic positioning block 11. Following the above assembly method, the assembly rod 6 of the collector body 5 is installed on the three sides of the assembly rod 2. The insulating rod wire 7 and the photoelectric receiving wire 8 are then inserted and connected to the phase acquisition of the ring main unit or switch cabinet to collect phase data. This allows the three phase acquisition devices to be connected. The acquisition unit 5 is integrated into the main body 1 of the instrument to facilitate the acquisition of different phase data when collecting multi-phase data from ring main units and switch cabinets. This allows the main body 1 to have multiple probe acquisition units for different phase acquisitions, avoiding misuse and misapplication that could damage the acquisition unit when acquiring multi-phase ring main units and switch cabinets. This further improves the convenience of the acquisition unit in phase acquisition and facilitates the disassembly and replacement of the phase acquisition unit. After the acquisition unit 5 is started by the switch, the photoelectric receiving wire 8 collects the optical signal containing frequency and phase information. The photoelectric conversion module conditions and amplifies the optical signal to convert it into an electrical signal. The measurement circuit measures the electrical signal, and then the microcontroller processes the measurement results. The antenna main body 14 is used to exchange data with other devices to realize the wireless transmission of phase information.
