Description

Technical Field

[0001] The present invention relates to the technical field of anti-electricity theft equipment, and in particular to an anti-electricity theft simulation test equipment. Background Art

[0002] In the field of operation and management of today's power system, anti-electricity theft is of vital importance. As the means of electricity theft become more diverse and covert, anti-electricity theft simulation test equipment has emerged to effectively detect and prevent electricity theft. Such equipment can simulate a variety of electricity theft scenarios, help power workers become familiar with electricity theft methods, test the effectiveness of anti-electricity theft measures, and thus ensure the safety and fairness of electricity supply, and safeguard the legitimate rights and interests of power supply companies and users.

[0003] In terms of mechanical structure, traditional anti-electricity theft simulation test equipment mostly uses a relatively simple and direct screw fastening method to assemble the device shell. Taking common test equipment as an example, its bottom shell and top shell are usually completely fixed and connected by a large number of screws. After the internal circuit board and other components are installed, the top shell is tightly covered on the bottom shell, and then the screws are tightened one by one along the edge of the shell to make the two tightly combined. This mechanical technology ensures the integrity of the equipment to a certain extent, but problems gradually emerge during long-term use.

[0004] When the internal circuit board of the equipment fails and needs to be repaired, this traditional screw fastening method exposes many disadvantages. In the actual power laboratory scenario, after the maintenance personnel receive the maintenance task, the first thing they have to face is the tedious work of removing a large number of screws. Due to the large number of screws and the rust and stripping after long-term use, the difficulty of disassembly increases greatly, which consumes a lot of time and physical strength. Moreover, when reinstalling, you need to carefully align the screw holes. A slight deviation will cause the screws to fail to go in, further extending the maintenance time. This not only affects the maintenance efficiency of the equipment, but also delays the research and testing of electricity theft detection technology due to long-term downtime, which cannot meet the current needs of quickly responding to power problems and efficiently carrying out anti-electricity theft work. Therefore, this field technology proposes an anti-electricity theft simulation test equipment to solve the above problems. Summary of the invention

[0005] In order to make up for the above shortcomings, the present invention provides an anti-electricity theft simulation test device, which aims to improve the problem that when the internal module of the anti-electricity theft simulation test device in the prior art fails and needs to be disassembled for maintenance, it is troublesome to loosen the screws one by one with the help of tools under the traditional installation method.

[0006] To achieve the above object, the present invention provides the following technical solution: an anti-electricity theft simulation test device, comprising a bottom shell, a top shell and an assembly component, wherein the assembly component is arranged on the outside of the bottom shell, a circuit board is installed inside the bottom shell, and the circuit board is connected to four wiring harnesses, and a disassembly assembly is arranged on the inside of the top shell, and the disassembly assembly is used to disassemble and separate the bottom shell and the top shell;

[0007] The disassembly and assembly assembly includes a guide rod, both ends of which are fixedly connected to the inner walls of the top shell, the outer sleeve of the guide rod is provided with two sliding plates, the outer sides of the sliding plates are fixedly connected with a clamping block, the outer side of the sliding plates is fixedly connected with an arc block, and is located above the clamping block, the outer side of the bottom shell is provided with two clamping holes, the outer side of the top shell is provided with two arc grooves, and the outer sleeve of the guide rod is provided with a spring.

[0008] Furthermore, the outer side of the sliding plate is slidably connected to the inner side of the top shell, and the outer side of the clamping block is clamped in the inner side of the clamping hole.

[0009] Furthermore, the outer side of the arc block is slidably connected to the inner side of the arc groove, and the two ends of the spring are fixedly connected to the outer sides of the two sliding plates respectively.

[0010] Furthermore, two knobs are rotatably connected to the outer side of the bottom shell, one end of the rotating shaft of the knob is fixedly connected to an arc rod, and a torsion spring is sleeved on the rotating shaft of the knob.

[0011] Furthermore, both sides of the inner wall of the top shell are fixedly connected with hanging tubes, and the outer side of the arc rod is in contact with the inner side of the hanging tube.

[0012] Furthermore, the assembly component includes four bolts, and the four bolts are arranged on the outside of the bottom shell. Two positioning clips are fixedly connected to both sides of the outside of the bottom shell.

[0013] Furthermore, an elastic ring is sleeved on the outside of the bolt, the outer side of the elastic ring fits with the outer side of the positioning clamp, the outer side of the bolt contacts the inner side of the positioning clamp, and one end of the bolt is connected to the inner thread of the outer base of the bottom shell.

[0014] The present invention has the following beneficial effects:

[0015] 1. In the present invention, if the circuit board module inside the equipment fails, the maintenance personnel gently pinch the two arc blocks with the thumbs and index fingers of both hands, apply pressure steadily, drive the sliding plate to move along the guide rod, make the card block disengage from the card hole, then turn the knob to overcome the resistance of the torsion spring, let the arc rod disengage from the hanging tube, release the second restraint, and the bottom shell and the top shell can be easily separated. Compared with the traditional screw fastening method, there are fewer steps, smoother operation, and save maintenance time.

[0016] 2. In the present invention, the bottom shell is placed to align the four positioning clips with the base installation points, and then holes are drilled with an electric drill, and elastic rings are put on. Bolts are passed through the inside of the positioning clips and tightened. The elastic rings can prevent the bolts from loosening and reduce the travel distance. When dismantling, loosen the bolts and move the bottom shell in the opposite direction of the positioning clip notch. The operation is easy and reduces the burden on personnel.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The standard parts used in this application can all be purchased from the market, and special-shaped parts can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, and bonding in the existing technology, and the components used for circuit connection are all conventional models in the existing technology.

[0026] At the same time, in order to clearly express the connection relationship and working principle between the components and highlight the key points, the drawings in the specification are organized and drawn in the form of simple diagrams. One simple diagram can correspond to a variety of materials and actual external structural shapes.

[0027] Reference Figure 1-Figure 5 , an embodiment provided by the present invention: an anti-electricity theft simulation test equipment, a bottom shell 1, a top shell 2 and an assembly component, the assembly component is arranged on the outside of the bottom shell 1, a circuit board is installed inside the bottom shell 1, and the circuit board is connected to four harnesses 16, the four harnesses 16 are responsible for transmitting various electrical signals, and transmitting the data collected and processed by each module on the circuit board to the corresponding monitoring and control unit, so as to ensure the normal operation of the entire simulation test equipment. A disassembly assembly is arranged on the inner side of the top shell 2, and the disassembly assembly is used to disassemble and separate the bottom shell 1 and the top shell 2; the disassembly assembly includes a guide rod 3, the two ends of the guide rod 3 are fixedly connected to the two sides of the inner wall of the top shell 2, and provide stable support and guidance for the movement of subsequent components, the outer sleeve of the guide rod 3 is provided with two sliding plates 4, the sliding plates 4 can slide smoothly left and right along the guide rod 3, and the outer side of the sliding plate 4 is fixedly connected with a card block 5, the outer shape of the card block 5 is perfectly matched with the two card holes 6 opened on the outer side of the bottom shell 1, when the two are engaged, it is ensured that the structure of the device is stable during operation and will not be easily loosened. An arc block 7 is fixedly connected to the outer side of the sliding plate 4 and is located above the clamping block 5. Two clamping holes 6 are provided on the outer side of the bottom shell 1, and two arc grooves 9 are provided on the outer side of the top shell 2. A spring 8 is sleeved on the outside of the guide rod 3, and its two ends are respectively fixedly connected to the outer sides of the two sliding plates 4. Under normal circumstances, the spring 8 uses its own elastic force to push the two sliding plates 4 to both sides, so that the clamping block 5 is firmly clamped in the clamping hole 6 to maintain the close connection between the bottom shell 1 and the top shell 2. Only when external force presses the arc block 7, the spring 8 will shrink, drive the sliding plate 4 to move, and then let the clamping block 5 disengage from the clamping hole 6. The outer side of the sliding plate 4 is slidably connected to the inner side of the top shell 2, the outer side of the clamping block 5 is engaged with the inner side of the clamping hole 6, the outer side of the arc block 7 is slidably connected to the inner side of the arc groove 9, and the two ends of the spring 8 are respectively fixedly connected to the outer sides of the two sliding plates 4. The outer side of the bottom shell 1 is rotatably connected to two knobs 10, and one end of the rotating shaft of the knob 10 is fixedly connected to an arc rod 11. A torsion spring is sleeved on the rotating shaft of the knob 10, which always applies a rotational force to the knob 10, so that the arc rod 11 is tightly against the hanging tube 12 under normal conditions. The hanging tube 12 is fixedly connected to both sides of the inner wall of the top shell 2, and the outer side of the arc rod 11 is in contact with the inner side of the hanging tube 12. The cooperation of the arc rod 11 and the hanging tube 12 constitutes a second fastening defense line of the combination of the bottom shell 1 and the top shell 2, further enhancing the overall stability of the equipment.

[0028] Specifically, during the long-term use of the device, it is inevitable that the modules on the circuit boards inside the bottom shell 1 and the top shell 2 will fail. At this time, the maintenance personnel need to disassemble the machine for inspection. During the operation, the two arc blocks 7 can be stably pinched and pressed with the thumbs and index fingers of both hands at the same time. When the arc blocks 7 are evenly pressed, the sliding plate 4 can be driven to move smoothly along the guide rod 3, providing accurate guidance for the movement of the sliding plate 4 to ensure that its movement direction does not deviate. Then let the sliding plate 4 drive the block 5 to steadily detach from the inside of the card hole 6, and then slowly turn the two knobs 10 with your fingers. When the knob 10 rotates, the torsion spring set at its shaft will produce a certain resistance, and always apply a rotation force to the knob 10, trying to return the knob 10 to its original position. However, we overcome this rotation force with appropriate force, so that the arc rod 11 rotates accordingly, and finally detaches from the inside of the hanging tube 12, and then the bottom shell 1 and the top shell 2 can be easily separated. This innovative disassembly method is more convenient and efficient than the traditional method of relying solely on screw fastening. In addition, the double limit of the block 5 and the arc rod 11 will provide double insurance for the device when the bottom shell 1 and the top shell 2 are combined together, making its structure more solid and stable, providing solid protection for the stable operation of the device.

[0029] Reference Figure 1-Figure 5 The assembly component includes four bolts 15, which are key components for fixing the bottom shell 1 to the external base. The four bolts 15 are arranged on the outside of the bottom shell 1, and two positioning clips 13 are fixedly connected to both sides of the outside of the bottom shell 1. The positioning clips 13 not only play the role of assisting the positioning bolts 15, but also provide convenience for the disassembly of the bottom shell 1 due to its unique structural design. An elastic ring 14 is sleeved on the outside of the bolt 15, and its outer side is fitted with the outer side of the positioning clip 13. The outer side of the bolt 15 contacts the inner side of the positioning clip 13, and one end of the bolt 15 is connected to the internal thread of the external base of the bottom shell 1.

[0030] Specifically, when we start to assemble and fix the equipment, we need to place the bottom shell 1 on the external base. We must pay special attention to the placement of the bottom shell 1. We must ensure that the four positioning clips 13 are aligned with the installation points on the base that have been accurately planned in advance. Any deviation of the positioning clip 13 will hinder the installation of the subsequent bolts 15, and the effect of stable connection cannot be achieved. After confirming that the bottom shell 1 is placed correctly, you need to use an electric drill or other suitable tools to drill holes in the base. Operate carefully according to the specifications of the bolts 15. The hole diameter should be slightly larger than the outer diameter of the bolt 15, and it is usually appropriate to reserve a gap of 0.5-1 mm. This can ensure that the bolt 15 can pass through smoothly without hindrance, and the bolt 15 will not shake in the hole due to the large hole diameter, affecting the fixing effect. After drilling the hole, the elastic ring 14 is put on the bolt 15. The elastic ring 14 is soft and elastic. During the insertion process, its outer side fits tightly with the outer side of the positioning clip 13, which greatly increases the friction and effectively prevents the bolt 15 from accidentally loosening due to vibration and other factors during subsequent use. At the same time, it also cleverly reduces the travel distance of the bolts 15. When the bottom shell 1 needs to be removed, the operator only needs to simply loosen the bolts 15 without spending a lot of energy to completely unscrew all the bolts 15 from the holes as in the traditional installation method. Then, the bottom shell 1 is moved in the opposite direction from the notch of the positioning clamp 13 with a steady and even force. In this way, the bottom shell 1 can be easily and conveniently disassembled, which greatly reduces the workload of the experimenter and makes the maintenance and inspection of the equipment efficient and quick.

[0031] The hardware composition of the anti-electricity theft simulation test equipment includes the following modules:

[0032] Power module:

[0033] Provides a stable power supply for the entire simulation test equipment. Usually includes AC power supply and DC power supply. The AC power supply can simulate the power supply of the actual power grid and output AC power of different voltage levels (such as 220V, 380V, etc.) and frequencies (50Hz or 60Hz). The DC power supply is used to provide power for some detection circuits, control circuits, etc. that require DC power supply. The power module is operated by an external connection harness 16.

[0034] Metering module:

[0035] This is one of the core components used to accurately measure electrical energy. It generally includes a smart meter, which can measure voltage, current, power, electrical energy and other parameters with high accuracy. Some metering modules also have a communication interface that can transmit metering data to a host computer for analysis.

[0036] Load Module:

[0037] Used to simulate actual electrical loads. Including various types of resistance, inductance, and capacitance loads to simulate pure resistance loads (such as incandescent lamps), inductive loads (such as motors), and capacitive loads (such as capacitor banks) and other different electrical equipment. By adjusting the size and nature of the load, different power usage scenarios can be simulated.

[0038] Electricity theft simulation module:

[0039] This is an important module unique to the anti-electricity theft simulation test equipment. It can simulate a variety of common electricity theft methods, such as short-circuiting the current loop to steal electricity, changing the meter voltage coil wiring to steal electricity, using a meter invertor to steal electricity, etc. This module usually includes some circuit elements and connection lines that simulate electricity theft, such as relays, simulated meter wiring terminals, etc., and can flexibly set the electricity theft method.

[0040] Detection and control module:

[0041] Equipped with various sensors, such as current sensors, voltage sensors, etc., for real-time detection of voltage and current signals in the circuit. At the same time, the module also includes a controller, such as a microcontroller (MCU) or a programmable logic controller (PLC), for controlling the entire simulation test process. It can control the operation of power supply, load, power theft simulation and other modules according to the preset parameters and detected signals, and judge and alarm abnormal situations.

[0042] Communication module:

[0043] Realize the communication between the equipment and external equipment (such as host computer, monitoring system, etc.). A variety of communication methods can be used, such as RS-485, Ethernet, ZigBee, etc. Through the communication module, various data during the experiment (such as measurement data, detected abnormal data, etc.) are transmitted to external equipment for further analysis and processing.

[0044] Host computer software:

[0045] The host computer software runs on the computer and is connected to the test equipment through the communication module. It can realize remote control of the experimental equipment, such as setting experimental parameters, starting / stopping experiments, etc. At the same time, it can receive and display various data during the experiment, and display the changes in data such as power metering and electricity theft detection in the form of intuitive charts and curves, which is convenient for users to analyze.

[0046] The metering module, the load module, the electricity theft simulation module, the detection and control module and the communication module are all installed on a circuit board inside the bottom shell 1 .

[0047] Steps:

[0048] Preparation before the experiment:

[0049] Check the hardware connection of the equipment: Ensure that the connection between the power module, metering module, load module, power theft simulation module, detection and control module and communication module is correct. Check whether the power cord and signal line of each module are firmly connected to avoid looseness during the experiment, which may cause data abnormality or equipment damage.

[0050] Turn on the device power: First, turn on the power switch of the power module to power the entire device. Observe whether the power indicator lights of each module are on normally to confirm that the device is powered on normally.

[0051] Start the host computer software: Start the host computer software that is compatible with the anti-electricity theft simulation test equipment on the computer. Connect the computer to the communication module of the equipment through a communication line (such as USB to RS-485 line, etc.) to ensure that the software can correctly identify the device and establish a communication connection.

[0052] Set the experimental parameters:

[0053] Set the power supply parameters in the host computer software, such as output voltage, frequency, etc. For example, if you want to simulate a residential power consumption scenario, you can set the AC power supply output voltage to 220V and the frequency to 50Hz.

[0054] Set the load parameters and select the load type and size according to the purpose of the experiment. If you want to simulate the power consumption of the inductive load in the factory, you can select a suitable inductive load and set its inductance value and current size. For example, select an inductive load with an inductance of 10mH and simulate different load powers by adjusting the current size.

[0055] Configure the power theft simulation parameters and select the power theft method to be simulated, such as short-circuiting the current loop to steal power. Set the time and degree of power theft. For example, set the simulation of short-circuiting the current loop to start 10 minutes after the experiment starts, and the degree of short-circuiting is to reduce the current loop resistance by 50%.

[0056] Start the experiment:

[0057] The experiment is started by sending the experiment start command through the host computer software. At this time, the power module starts to output power according to the set parameters, and the load module is connected to the circuit to start simulating power consumption. The sensors in the detection and control module start to collect voltage, current and other signals in real time and transmit the data to the controller.

[0058] Observe the working condition of the metering module to check whether the smart meter can accurately measure the electric energy. At the same time, pay attention to the changes in the electric energy parameters (such as voltage, current, power, electric energy, etc.) displayed on the upper computer software interface to confirm whether they meet the set experimental parameters.

[0059] Simulate electricity theft operation and detection:

[0060] When the experiment reaches the preset power stealing time, the power stealing simulation module operates according to the set power stealing mode. For example, in the short-circuit current loop power stealing simulation, the corresponding relay operates to short-circuit part of the current loop.

[0061] The sensors in the detection and control module will immediately detect changes in circuit parameters, such as a sudden decrease in current. The controller analyzes and judges these changes based on the preset electricity theft detection algorithm. At the same time, the host computer software will receive abnormal data and issue an alarm prompt (such as a sound alarm, pop-up alarm, etc.).

[0062] Observe the effect of anti-electricity theft detection, check whether the detection and control module can accurately identify the electricity theft behavior, as well as the identification time, accuracy, etc. For example, record the time interval from the occurrence of electricity theft to the system issuing an alarm to evaluate the timeliness of the detection system.

[0063] End of experiment and data processing:

[0064] After the experiment is over, a stop command is sent through the host computer software to turn off the power switch of the power module to end the experiment.

[0065] View and save the data during the experiment in the host computer software, including various power parameters and alarm information during the normal power consumption stage and the power theft stage. Analyze these data, such as comparing the changes in power metering before and after the power theft, and analyzing the performance indicators of the detection system (such as detection accuracy, false alarm rate, etc.). According to the experimental results, evaluate the effectiveness of anti-power theft measures and provide reference for actual anti-power theft work.

[0066] Working principle:

[0067] First, the bottom shell 1 can be placed on the external base, and then a hole is drilled on the base with an electric drill or other tools, and then the elastic ring 14 is put on the bolt 15, and then the bolt 15 can pass through the inner side of the positioning clamp 13 and be tightened in the hole to fix the bottom shell 1. The function of the elastic ring 14 is to increase the friction force while reducing the travel distance of the bolt 15, so that when the bottom shell 1 is removed, the bolt 15 can be simply loosened, and then the bottom shell 1 can be moved in the opposite direction from the notch of the positioning clamp 13, so that the bottom shell 1 can be easily disassembled without deliberately unscrewing all the bolts 15 from the holes, thereby reducing the workload of the experimenter;

[0068] In addition, when a module on the circuit board inside the bottom shell 1 and the top shell 2 fails, the two arc blocks 7 can be pinched and pressed at the same time to drive the sliding plate 4 to move, and then the sliding plate 4 drives the card block 5 to disengage from the inside of the card hole 6, and then the two knobs 10 are turned to make the arc rod 11 rotate and disengage from the inside of the hanging tube 12. In this way, the bottom shell 1 and the top shell 2 can be easily separated, which is more convenient to disassemble than the traditional screw fastening method. In addition, the double limit of the card block 5 and the arc rod 11 will also be more firm and stable when the bottom shell 1 and the top shell 2 are combined together.
