Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of insulation detection, and relates to a preventive test detection device, a detection system and a detection method for an insulation wearable for live working. BACKGROUND

[0002] In the prior art, the insulation safety protection tool generally comprises an insulation boot / glove, an insulation rod and an insulation pad. In order to realize detection of the tools, an insulation boot / glove test cabinet, an insulation rod test support, an insulation pad test platform and an overall control cabinet need to be arranged in a detection center. The insulation boot / glove test cabinet is mainly used for simultaneously detecting a large number of insulation boots / gloves, and has a large overall floor area and low detection efficiency for small batches of insulation boots / gloves. The traditional insulation rod test support is horizontally placed, and needs to be placed between a high-voltage support and a grounding support during use, and the interval of the high-voltage support and the grounding support needs to be adjusted according to the length of the insulation rod, which also leads to a large floor area of the entire detection support. As can be seen, the existing insulation boot / glove test cabinet, insulation rod test support, insulation pad test platform and overall control cabinet are all independent and dispersed devices, have a large overall floor area, are inconvenient to carry and cannot provide on-site insulation detection services.

[0003] At present, the insulation tool test equipment on the market at home and abroad mainly has single test functions. For example, the insulation boot(glove) test tool can only measure a single product, and the remaining insulation rod, insulation pad and grounding wire test products need to be tested separately, and the products cannot be used multiple times. Moreover, the equipment occupies a large area, and a set of test products often occupies an area of (3-4) m 2 . The dispersed functions of the equipment cannot be utilized centrally, and there are safety hazards. The test results are recorded manually or printed by a micro printer, and there are no process data, which is not convenient for archiving and management. There is no data interface, and the equipment cannot be connected to other systems. The equipment has poor expandability, and upgrading and expansion are difficult.

[0004] In addition to the problems such as single function and poor expandability, there are some problems in the storage and management of electric power safety tools in production enterprises and quality inspection units.

[0005] Because the use unit, production unit and quality inspection unit of the electric power safety tool are not large in scale, the storage condition after product production (inspection) is limited, most enterprises adopt the method of centralized stacking when storing, and the storage environment is mostly the general natural environment condition (a large number of products are stacked on the ground of the finished product warehouse, but for many products related to electricity, such as insulating rods, the bracket is not allowed to be placed on the ground). This natural stacking method is simple, but cannot meet the storage requirements of the product standard, and the storage of some units is in a disordered state. The above-mentioned non-standard storage method is extremely likely to cause adverse effects on the performance of the tool, thereby forming a safety hazard, and ultimately leading to an accident.

[0006] Most tool manufacturers, use units and detection units lack systematic management of the life cycle of the tool, and can even be said to be in a state of no management. Each time it needs to be used, it is temporarily tested, and some even check only the appearance of the tool before taking it to the site for use. For overdue products and products that have reached the scrap period, there is no early warning information, limited detection of unqualified and scrapped products, and the use or detection of safety tool laboratories is lack of unified management, which not only causes waste of time cost and resource cost, but also brings serious safety hazards. SUMMARY

[0007] In order to solve the problems in the prior art, the purpose of the present application is to provide a portable insulating clothing for live working preventive test detection device, which not only reduces the floor area of the whole device, but also is convenient to carry and can realize on-site service of insulation detection.

[0008] The portable insulating clothing for live working preventive test detection device provided in the present application comprises: an insulating clothing test device, a step-up transformer and a voltage control device; the portable insulating clothing for live working preventive test detection device can be placed on a material flat car for convenient movement; in use, the insulating clothing test device, the step-up transformer and the voltage control device are connected through wires and / or cables and the like structure;

[0009] In one specific embodiment, the voltage control device can also be connected to some parts that are not directly connected through wires and / or cables and the like structure, such as a high-voltage module and the like structure, through Bluetooth and the like wireless form.

[0010] The insulating clothing test device is used for putting and installing insulating safety protection tools, and performing power frequency withstand voltage test on the insulating safety protection tools (including insulating boots, insulating gloves and the like). After installing the insulating boots (or insulating gloves and the like), the connection of wires and / or cables and other auxiliary work are completed, and then the corresponding test can be performed;

[0011] The step-up transformer is used to increase the received voltage and transmit to the insulating wear test device, that is, receive low voltage and increase the voltage when transmitting to the insulating wear test device, while keeping the frequency unchanged during transmission.

[0012] The voltage control device is used to control the voltage in the detection device, in particular, the test parameters of the step-up transformer can be set and the related voltage, current and the like are displayed; the test parameters include: test voltage, test current and voltage duration.

[0013] The use of the portable insulating wear preventive test detection device for live working in the application mainly includes: detecting the insulation state in the electrical system to ensure the safe operation of the electrical equipment; at the same time, testing the insulating boots (or insulating gloves, etc.) and reading the leakage current to protect the safety of personnel and equipment; the portable insulating wear preventive test detection device for live working in the application is an automatic step-up (step-down) voltage testing insulation tool, which can also automatically print test data, improve testing efficiency and accuracy; used for batch testing of insulating boots (gloves) safety tools, simplifying the testing procedure and improving the detection speed.

[0014] The insulating wear test device comprises a test water tank, a high-voltage module, one or more fixed guide rail bases and one or more insulating supports.

[0015] The one or more fixed guide rail bases are fixedly arranged below the high-voltage module; the insulating support is provided with a groove penetrating up and down and matching the shape and size of the fixed guide rail base, and the insulating support is installed and arranged on the opposite sides inside the test water tank, which can be manually controlled to move up and down in the groove in the insulating support according to the actual working conditions, adjusted within a certain stroke, realize the lifting of the high-voltage module, and meet the test requirements of different environments.

[0016] The test water tank comprises a water tank shell, a water tank liner and an automatic water injection module; the water tank shell is grounded and must have good contact with the ground; the water tank liner is used to receive the conductive medium for testing, and the conductive medium comprises steel balls or tap water; the automatic water injection module is fixedly installed on one side of the water tank liner and connected with a water pump, and the automatic water injection module performs automatic water injection action according to the external signal of the voltage control device.

[0017] The test water tank is used to place the insulating safety protection tool to be tested.

[0018] The outer side of the fixed guide rail base has one or more slots that match one or more buckles on the insulating bracket. One side of each buckle has a protruding snap that can be inserted into the slot to fix the insulating bracket to the fixed guide rail base. Specifically, the fixed guide rail base can be fixed to the insulating bracket by pushing the buckle out horizontally. The buckle can be freely adjusted in height when it is pushed back.

[0019] An automatic water injection module is also fixedly installed on one side of the inner tank of the water tank. The automatic water injection module is connected to the water pump (driver) and works in conjunction with the flow meter and universal joint. An external DC12V electrical signal controls whether the driver performs the water injection action. The universal joint includes an adjustment knob and a rotating valve, which can adjust the angle and amount of water outlet so that the injected water can flow into the insulating safety protection tool at a suitable angle. The flow meter monitors the water injection volume in real time and feeds it back to the voltage control device. After the insulating safety protection tool (such as insulating boots, insulating gloves, etc.) has been filled with water, the power frequency withstand voltage test can be performed.

[0020] The insulating bracket can isolate the high-voltage module from the structure of the water tank, so that the structure of the water tank and the high-voltage module maintain a safe distance.

[0021] The high-voltage module has one or more high-voltage module covers on its top, which are opened for installation or maintenance. The high-voltage module houses a battery pack and a current sensor unit. The external side of the high-voltage module features a battery level meter, operation buttons, and indicator lights. The battery level meter displays the battery level, reducing external wiring and preventing other lines from contacting the high voltage. When the battery level is low, the operator can visually check and recharge it promptly. The battery pack provides power to the current sensor, which collects the test current. The operation buttons, located on the back of the high-voltage module, control various sensors, electronic devices, and other downstream electrical equipment, effectively conserving battery power when the high-voltage module is not in operation. One or more indicator lights, located on the front of the high-voltage module, display the test results for different workstations: green for a successful test and red for a failed test.

[0022] In one specific embodiment, the current sensor can also be replaced by a leakage current acquisition plug to acquire the test current.

[0023] In one specific embodiment, one or more eye bolts may be installed at the bottom of the high-voltage module. One end of the eye bolt is tied with a rope and the other end is tied with a clamp for clamping the insulation safety protection tool to be tested, so as to prevent the insulation safety protection tool from falling off after water is injected.

[0024] The bottom of the high-voltage module can also be equipped with several hooks, on which conductive chains are attached. One end of the conductive chain is connected to the high-voltage module, and the other end hangs down and is placed in the insulating safety protection tool. During the test, the chain forms an equipotential with the interior of the insulating safety protection tool.

[0025] The step-up transformer is used to generate AC voltage and includes a transformer, a moving roller, and a protective plate for increasing voltage and controlling current.

[0026] The protective plate is fixed to the transformer by one or more bolts or other structures; an adapter plug is installed on one side of the protective plate, one end of which is connected to the high-voltage module of the insulating wearable test device via a high-voltage cable, and the other end is connected to the busbar of the step-up transformer; the protective plate also has a reserved docking connector, which can be connected to voltage control equipment to facilitate the control of low-voltage circuit electrical components; the movable rollers are fixedly installed at the bottom of the transformer to facilitate the movement of the transformer.

[0027] The voltage control device is installed in the chassis. The panel of the voltage control device is equipped with one or more aviation connectors (including a first aviation connector and a second aviation connector), a touch screen, a grounding post, an emergency stop button, panel indicator lights, and an Ethernet interface. The voltage control device can control the step-up transformer to achieve low voltage driving high voltage.

[0028] The first air-mounted connector is used to drive the voltage of the step-up transformer to rise or fall; the second air-mounted connector is connected to the automatic water injection module in the test water tank and is used to drive the automatic water injection module to work or stop, so as to realize automatic water injection.

[0029] The touch screen is used for the control output of the insulating wearable testing device, the display of various test data, and / or the display of various alarm information;

[0030] The grounding post is used to ground the voltage control device, so that the voltage control device is in a stable potential state;

[0031] The emergency stop button is used to cut off the power output in abnormal situations. Pressing the button will stop all power output and play a protective role.

[0032] The panel indicator lights are used to indicate the test status. A red panel indicator light indicates a test failure. That is, the indicator lights on the high voltage module directly display the test results, while the indicator lights on the voltage control equipment display the test status.

[0033] The Ethernet interface is used to communicate with external devices via an Ethernet cable.

[0034] In this invention, the insulating tool testing device, the step-up transformer device, and the voltage control device can be uniformly placed on a material flatbed cart. The material flatbed cart can be freely raised and lowered for transporting, unloading, and loading the portable live-line working insulating wear preventive testing device. Only one person and one cart are required, which greatly reduces labor costs, allows for flexible testing without requiring more manpower, and enables free and flexible movement with the truck.

[0035] The present invention also provides an insulation safety protection tool testing system, the testing system including the above-mentioned testing device, barcode scanner, 5G IoT module, security monitoring module, and lifecycle management module; the testing device, the barcode scanner, the 5G IoT module, the security monitoring module, and the lifecycle management module are all connected to a data center for data exchange and processing;

[0036] The testing device is used to test the insulation performance of insulated safety protection tools;

[0037] The barcode scanner is used to scan codes to obtain production information and national standard test information of insulating safety protection tools;

[0038] The 5G IoT module connects to the voltage control equipment via a wired network cable. It can be installed independently on a desktop, with pre-configured communication parameters, requiring no further operation. Other devices can then remotely access the data via 5G Wi-Fi. The 5G IoT module aggregates all test data, stores it in a standard database, and interacts with the MES system (or the State Grid EIP system) via Ethernet to achieve terminal access control and monitoring. Test data is stored in an ACCESS database, connected to a server network. Local test data is uploaded to the server database, and the test center can parse relevant information from the database, enabling flexible storage and retrieval of test data, personnel information, and other related data. Ultimately, this achieves data sharing between the test area system and the test center system, realizing the purpose of 5G IoT.

[0039] The security monitoring module detects personnel entering during the test process, triggers an alarm and / or terminates the test, thus avoiding potential safety hazards during the test.

[0040] The lifecycle management module acquires production information and historical testing information to perform lifecycle management on insulation safety protection tools.

[0041] In actual use, a QR code label is affixed and fixed to the insulating safety protection tool to be tested. The QR code label is used to store the basic information of the insulating safety protection tool. The basic information includes: production information and national standard test information. The production information includes: manufacturer, production date, product name, product number, and scrap age. The national standard test information includes: standard voltage parameters, standard current parameters, standard withstand voltage duration, and standard testing cycle. The QR code label is identified by the barcode scanner to obtain the production information and the national standard test information.

[0042] The voltage control device, the 5G IoT module, and the barcode scanner can be additionally connected to a laptop computer, which connects to the aforementioned structure wirelessly.

[0043] The laptop computer can acquire production information, national standard test information, test voltage, leakage current, and test date of the insulating safety protection tool; determine the test parameters based on the national standard test information; save the test voltage, leakage current, and test date as historical test information to the QR code label; and perform lifecycle management of the insulating safety protection tool based on the production information and historical test information. The lifecycle management includes: information query, test date warning, and insulating tool scrap warning. Specifically, the insulating tool test date warning can be determined by the difference between the current date and the last test date, comparing this difference with the national standard test cycle to determine the final result, and can also be displayed to the user using flashing pop-up windows of different colors.

[0044] This invention can also utilize 5G IoT technology and remote communication technology to achieve remote testing. After on-site personnel confirm that everything is normal, testing personnel can issue commands directly from elsewhere to remotely control the testing equipment in the on-site laboratory. Upon completion of the test, the data is transmitted back to the central laboratory in real time, where testing personnel analyze and judge the results to meet the customer's rapid needs.

[0045] The present invention also provides a method for testing insulating safety protective tools, the method comprising the following steps:

[0046] Step 1: Set the test parameters for the insulation safety protection tool to be tested;

[0047] Step 2: Place the insulating safety protection tool on the work station of the insulating wear test device in the live-line working insulating wear preventive testing and detection device;

[0048] Step 3: Connect the connecting cables between the various devices of the live-line working insulating wear preventive testing device, inject conductive medium into the insulating safety protection tool, operate on the voltage control device panel, start the test, the device automatically boosts the voltage to the target voltage, automatically times the time, automatically stops the test when the set time is reached, disconnects the high voltage bus, the voltage of the step-up transformer automatically returns to zero, and the system automatically judges the test results.

[0049] Step 4: End the test and obtain the withstand voltage test results for the insulation safety protection tools.

[0050] This invention also provides the application of the above-mentioned detection device, detection system or detection method in the rapid and convenient detection of insulating safety protection tools.

[0051] The beneficial effects of this invention include:

[0052] The portable live-line working insulating wear preventive testing device provided by the present invention is a complete whole through modular equipment and structure, and utilizes a material flatbed truck to transport voltage control equipment, step-up transformer and insulating wear testing device. The insulating wearable testing device mainly consists of a high-voltage module and a test water tank. During use, simply place the insulating boots or gloves in the test water tank and secure them with clips for testing. When not in use, simply store the insulating boots (gloves) and drain the water from the test tank. To save space and reduce size, the device fully utilizes the internal space of a material flatbed cart for testing insulating boots (gloves). During use, the step-up transformer and the insulating wearable testing device must be placed on the flatbed cart, with the voltage control equipment maintained at a safe distance from the cart, allowing for easy operation. When not in use, simply disconnect the high-voltage line between the step-up transformer and the insulating wearable testing device. The entire testing device makes full use of the material flatbed cart's space, simultaneously testing two workstations. Equipped with a 5G IoT platform, the overall design is simple and lightweight, better meeting the needs of on-site testing services for small batches of insulating tools (including insulating wearables such as insulating gloves and boots). After testing, the data is transmitted back to the central laboratory in real time for analysis and judgment by testing personnel to meet customers' rapid needs. Attached Figure Description

Detailed Implementation

[0066] The invention will be further described in detail below with reference to the specific embodiments and accompanying drawings. Except for the contents specifically mentioned below, the processes, conditions, and experimental methods for implementing the invention are all common knowledge and general knowledge in the art, and the invention does not have any particular limitations.

[0067] This invention provides a portable preventative testing device for insulating protective equipment used in live-line work. The testing device includes: an insulating protective equipment testing apparatus, a step-up transformer, and a voltage control device. The insulating protective equipment testing apparatus, the step-up transformer, and the voltage control device are connected by wires and / or cables. The insulating protective equipment testing apparatus is used to insert and install insulating safety protective tools and perform a power frequency withstand voltage test on the insulating safety protective tools. The step-up transformer is used to increase the received voltage and transmit it to the insulating protective equipment testing apparatus, while maintaining a constant voltage frequency. The voltage control device is used to control and regulate the voltage in the testing device. This invention also provides a testing system incorporating the above-mentioned testing apparatus, as well as a method and application for testing insulating safety protective tools.

[0068] Specifically, the purpose of this invention is to provide a portable preventive testing device for insulating clothing used in live-line work, which reduces the overall footprint of the device, is easy to carry, and enables on-site insulation testing services.

[0069] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] Figure 1An exemplary structure of a portable preventive testing device for insulating clothing used in live-line work is shown, and the various parts of the device are described in detail below.

[0071] The portable live-line working insulating wear preventive testing device described in this invention is mainly used to test insulating safety protection tools, which include insulating boots or insulating gloves.

[0072] The portable live-line working insulating wear preventive testing device of the present invention includes an insulating wear testing device 1, a step-up transformer 2, and a voltage control device 3;

[0073] like Figure 2 As shown, the insulating wearable testing device 1, the step-up transformer 2, and the voltage control device 3 are connected by wires and / or cables, etc.

[0074] See Figure 3 The insulating wearable testing device 1 includes: a test water tank 1.1, a high-voltage module 1.2, one or more fixed guide rail bases 1.3, and one or more insulating supports 1.4; in one specific embodiment, the insulating wearable testing device 1 includes two test stations, which can test two insulating boots or two gloves at a time.

[0075] Specifically, the insulating boots and gloves are placed in the test water tank 1.1; in order to make it easier and more secure to fix the insulating boots or gloves, multiple eye bolts can be installed at the bottom of the high voltage module 1.2, which are connected to ropes and clamps. The clamps are used to clamp the boot openings or glove openings to prepare for the next test.

[0076] Furthermore, a hook can be installed below the high-voltage module 1.2, and a conductive chain can be attached to the hook. One end of the conductive chain is connected to the high-voltage module 1.2, and the other end hangs down directly and is placed inside the insulating boot or glove to be tested, so that it forms an equipotential with the inside of the insulating safety protection tool during the test.

[0077] During the test, if the insulating boots or gloves fail the test, the current sensor unit inside the high-voltage module 1.2 will collect the test current in real time. When the test current exceeds the preset threshold, the insulating wearable test device 1 will alarm and automatically retract the hook to disconnect the conductive chain of the circuit. The high-voltage busbar of the circuit will be disconnected at the same time, and the red indicator light 1.2.4 on the front panel of the corresponding high-voltage module 1.2 will light up. Conversely, if the test is passed, the green indicator light 1.2.4 on the front panel of the high-voltage module 1.2 will light up.

[0078] In one specific embodiment, at least two clips are provided at one station of the insulating wearable testing device 1 to fix insulating boots or insulating gloves.

[0079] In one specific embodiment, the high-voltage module 1.2 has at least two hooks for vertically fixing the conductive chain.

[0082] exist Figure 3 In this process, the fixed guide rail base 1.3 can be manually adjusted up and down in the insulating bracket 1.4 according to actual needs. The fixed guide rail base 1.3 can be manually disengaged from the latches 1.4.1 on both sides to raise the fixed guide rail base 1.3 to the target height. Then the latches 1.4.1 can be pushed forward, and the front end of the latches 1.4.1 can be inserted into the slots 1.3.1 of the insulating bracket. This allows the high voltage module 1.2 to be adjusted in height to meet different test requirements.

[0083] exist Figure 3 In this system, the automatic water injection module 1.1.3 allows for manual adjustment of the water outlet angle and pressure via the knob 1.1.3.2 and the rotating water outlet valve 1.1.3.1, according to actual working conditions. During water injection, water is injected into the insulating boots and gloves at a suitable angle and normal pressure. A flow meter is connected in series in the circulating water circuit to automatically calculate the flow pulse and convert it into the water output. The water pump 1.1.4 is connected to the voltage control device 3 via a connector. When the water volume meets the demand, the power supply to the water pump 1.1.4 is cut off via an external signal output from the voltage control device 3, controlling the pump's on / off state and stopping the water injection process.

[0084] Furthermore, the detection device also includes: a step-up transformer 2 and a voltage control device 3;

[0085] Specifically, one end of the step-up transformer 2 is connected to the high-voltage module 1.2 of the insulating wearable test device 1, and the other end is connected to the first connector 3.3 of the voltage control device 3.

[0086] exist Figure 7 In the process, the preventive testing device for insulating wearables used in live-line work is controlled by a touch screen 3.2. According to national standards, the corresponding test data is set. After the test, the data is connected and interacted with the 5G Internet of Things platform and uploaded to the central laboratory.

[0087] The step-up transformer 2 is used to generate AC voltage (high voltage), and the test parameters include: test voltage, test current, and withstand voltage duration.

[0088] Specifically, the step-up transformer 2 includes a transformer 2.1, a moving roller 2.2, and a protective plate 2.3, as shown below. Figure 8 As shown;

[0089] The protective plate 2.3 is fixedly mounted on the transformer 2.1 by multiple bolts (e.g., 3, 4, 5, etc., depending on actual needs); an adapter plug is installed on one side of the protective plate 2.3, one end of which is connected to the high-voltage module 1.2 of the insulating wearable test device 1 via a high-voltage cable, and the other end is connected to the busbar of the step-up transformer 2; the protective plate 2.3 is provided with an aviation plug for interfacing with the voltage control device 3 for electrical control; the movable roller 2.2 is fixedly mounted on the bottom of the transformer 2.1.

[0090] In one specific embodiment, the voltage control device 3 has a box structure, which is small in size and easy to carry;

[0091] The voltage control device 3 is installed in the chassis 3.1. The panel of the voltage control device 3 is provided with one or more aviation connectors, a touch screen 3.2, a grounding post 3.5, an emergency stop button 3.6, panel indicator lights 3.7, and an Ethernet interface 3.8. The aviation connectors include a first aviation connector 3.3 and a second aviation connector 3.4.

[0092] The first connector 3.3 is used to drive the voltage of the step-up transformer 2 to rise or fall; the second connector 3.4 is connected to the automatic water injection module 1.1.3 in the test water tank 1.1 of the insulating wearable test device, and is used to drive the automatic water injection module 1.1.3 to work or stop, so as to realize automatic water injection.

[0093] The touchscreen 3.2 is used for the control output of the insulating wearable testing device, as well as the display of test data and / or alarm information;

[0094] The grounding post 3.5 is used to ground the voltage control device, so that the voltage control device is in a stable potential state;

[0095] The emergency stop button 3.6 is used to cut off the power output in abnormal situations. Pressing the emergency stop button 3.6 in an abnormal situation will stop all power output, thus protecting the equipment and personnel in case of an emergency.

[0096] The panel indicator light 3.7 is used to indicate the test status. When the panel indicator light 3.7 is lit up in red, it means that the test has failed.

[0097] The Ethernet interface 3.8 is used to communicate with external devices via an Ethernet cable.

[0098] This invention also provides an insulation safety protection tool testing system, which includes the aforementioned testing device, barcode scanner, 5G IoT module, security monitoring module, and lifecycle management module; the testing device, barcode scanner, 5G IoT module, security monitoring module, and lifecycle management module are all connected to a data center for data exchange and processing, such as... Figure 9 As shown;

[0099] The testing device is used to test the insulation performance of insulated safety protection tools;

[0100] The barcode scanner is used to scan codes to obtain production information and national standard test information of insulating safety protection tools;

[0101] The 5G IoT module is used to aggregate test data, store it in a standard database, and interact with the system via Ethernet to achieve terminal access control and terminal monitoring control.

[0102] The security monitoring module detects personnel entering during the test process, triggers an alarm and / or terminates the test, thus avoiding potential safety hazards during the test.

[0103] The lifecycle management module acquires production information and historical testing information to perform lifecycle management on insulation safety protection tools.

[0104] In practical implementation, this invention may also utilize devices such as QR code labels, barcode scanners, and laptops.

[0105] A QR code label is affixed to the insulating safety protection tool to be tested. The QR code label stores basic information about the insulating safety protection tool. The basic information includes: production information and national standard test information. The production information includes: manufacturer, production date, product name, product number, and scrap age. The national standard test information includes: standard voltage parameters, standard current parameters, standard withstand voltage duration, and standard testing cycle. A barcode scanner is used to identify the QR code label and obtain the production information and national standard test information.

[0106] The laptop connects to the voltage control equipment and the 5G IoT module. The laptop is used to: acquire production information, national standard test information, step-down voltage, leakage current, and test date of the insulating tools; determine test parameters based on the national standard test information; save the step-down voltage, leakage current, and test date as historical test information to a QR code; and perform lifecycle management of the insulating tools based on the production information and historical test information. Lifecycle management includes: information query, test date warning, and insulating tool scrap warning. Specifically, the test date warning for insulating tools is determined by the difference between the current date and the last test date. This difference is compared with the national standard test cycle to determine the final result, and different colored flashing pop-up windows also alert the user.

[0107] In a preferred embodiment, the detection system including the preventive testing device for insulating clothing used in live-line work can also be equipped with a security monitoring module. The security monitoring module is activated based on whether the detection device is ready to operate. Once the detection device is determined to be operational, it further determines whether unauthorized personnel have entered the test area. If unauthorized personnel do enter, the voltage output within the test area is immediately cut off, thereby achieving a safety protection function.

[0108] In a preferred embodiment, the testing system including the protective testing device for live-line working insulating wearables may further include a 5G IoT module. The 5G IoT module is used to aggregate all test data after the test and store it in a standard database. It interacts with the manufacturing enterprise's Manufacturing Execution System (MES) via Ethernet to achieve terminal access control and terminal monitoring control. Test data is stored in the form of an ACCESS database, connected to a server network. The test site uploads test data to the server database. The test center can parse the relevant information corresponding to the test sample from the database, enabling flexible storage and retrieval of sample information, test data, test personnel, and other related data. This achieves data sharing between the test area system and the test center system, ultimately enabling the entire portable protective testing device for live-line working insulating wearables to achieve… Figure 9 The effect of smart IoT is shown.

[0109] This invention provides a practical application scenario for a portable preventive testing and inspection device for insulating clothing used in live-line work. The specific process is as follows: Figure 10 As shown, it includes:

[0110] First, test samples are defined in the form of QR codes, with each test sample corresponding to a unique QR code.

[0111] The barcode scanner can scan the QR code on the test sample at the start of the test to automatically query national standard requirements, automatically set test parameters, and automatically control voltage and timing throughout the test. After the test is completed, the data is stored in the server for easy retrieval and report printing at any time. It can be integrated with the business management system, allowing users to scan and retrieve information corresponding to the test sample, thus achieving fully automated and intelligent control of the testing system. The QR code is defined in the format of company name + product name + product code + test date. Before the test begins, the test personnel generate the defined QR code using a QR code generator and then affix the QR code to a prominent position on the test sample.

[0112] Specifically,

[0113] Before the test begins, users log in and pass feature recognition. They then use a barcode scanner to scan the QR code on the test sample. The laptop reads the sample information stored in the QR code and automatically queries the test parameters in the national standard test information. It also automatically sets the test voltage, test current, withstand voltage duration, and standard values ​​of the testing device.

[0114] At the start of the test, the security monitoring module automatically determines whether the test area meets the conditions for starting the test (such as whether the access control of the test area is closed, whether there are people staying in the test area, etc.). The test is only allowed if the test conditions are met (that is, the security monitoring system detects that the user has the right to use the equipment and that no one has entered the test area). Otherwise, the test closing operation cannot be performed.

[0115] During the experiment, voltage control device 3 was used to control the voltage rise (fall) rhythm of step-up transformer 2, and to stably control the voltage rise and fall speed. (The controller sets the target voltage based on the information of the test sample and automatically controls the rise and fall speed. When the step-up transformer rises to half of the target voltage at a uniform speed, it gradually increases to the target voltage at a speed not exceeding 5% of the target voltage in each step. According to the error range set by the controller, when the voltage exceeds or approaches the target voltage, the step-up transformer rises (falls) to the target voltage within the allowable error range in smaller steps, and then the device starts timing. After the set time is reached, the experiment is stopped, and the experiment results are obtained and judged.)

[0116] Specifically, during the test, the voltage rise rate is intelligently controlled. In the initial stage of voltage rise, the voltage rises steadily at a rate of 5% of the rated voltage. When the voltage reaches 80% of the target voltage, the rise rate automatically slows down. When the target voltage reaches 90%, the rise rate slows down further. When the voltage automatically rises to the set value, the equipment automatically starts timing. When the timing is complete, the test results are displayed, and the equipment automatically returns to its initial state. Test data is stored in an ACCESS database and connected to a server network. The test site uploads test data to the server database. The business management system searches the server database name to parse the relevant information corresponding to the test sample, enabling flexible storage and retrieval of test sample information, test data, test personnel, and other related data. Ultimately, this achieves data sharing and smart IoT between the test area system and the office business administrator system.

[0117] Finally, after the experiment is completed, the test results are automatically written into the QR code corresponding to the test sample and uploaded to the terminal service platform.

[0118] After the 5G IoT platform completes the trial, all test data is aggregated and stored in a standard database. It then interacts with the MES system (or the State Grid EIP system) via Ethernet to enable terminal access control and monitoring. Test data is stored in an ACCESS database and networked through a server. Local test sites upload test data to the server database, while the test center can parse relevant information from the database, allowing for flexible storage and retrieval of test data, personnel information, and other related data. Ultimately, this achieves data sharing between the test area system and the test center system, fulfilling the purpose of 5G IoT.

[0119] This invention also utilizes a security monitoring module. This module applies the latest visual AI image recognition technology to the test area, employing a complete set of camera monitoring devices arranged in a surrounding layout throughout the entire test area. The module uses the readiness of the test platform as the activation condition. After the test platform begins operation, it determines whether unauthorized personnel have entered the test area and immediately cuts off the voltage output to the test area, thereby achieving the purpose of security protection.

[0120] To facilitate data analysis and management, a lifecycle management module is also installed on the computer. This module can comprehensively manage information such as the sample's entry time, testing time, testing data, and testing personnel. When a test sample is nearing its next testing deadline, the system can intelligently alert the testing personnel that the sample needs to be tested. If there are test samples that have reached their expiration date, it can also prompt the management personnel to handle and replace them in a timely manner.

[0121] Lifecycle management process design, such as Figure 10 As shown.

[0122] Specifically, the lifecycle management module is mainly divided into four functional areas: sample information management area, test area, testing date early warning area, and sample scrapping early warning area.

[0123] Sample Information Management Area: This area allows users to query and manage information such as the submitting unit, submission time, manufacturer, QR code, test data, test results, and test personnel for test samples.

[0124] Test area: After the barcode scanner scans the QR code of the test sample, the sample information stored in the QR code is uploaded to the computer. The computer receives and processes the sample information and automatically sets the test parameters in the controller according to the sample information, thus completing the information exchange between test data and service data.

[0125] Testing Date Warning Zone: Automatically queries the last test date of the test sample and automatically calculates the next test date based on the testing cycle required by the national standard for the corresponding test sample. It then displays a pop-up window on the tablet computer to remind the test personnel that the test sample is approaching its testing date and needs to be scheduled for testing, thus avoiding potential risks caused by continuing to use products that have exceeded their testing cycle.

[0126] Sample Disposal Warning Zone: When a test sample exceeds its testing cycle or has reached its service life and must be forcibly disposed of, a bright red flashing pop-up will appear on the tablet computer to remind management personnel to dispose of the test sample. This avoids unnecessary work caused by the testing personnel retesting the sample and eliminates the risks associated with continuing to use the test sample.

[0127] The lifecycle management module aims to manage power grid safety risks and operational safety risks. It focuses on strengthening the management of safety tools and equipment records, physical inventory, and usage. By integrating intelligent equipment control and intelligent data access, it standardizes the entire process of management and early warning for power safety tools and equipment, from inspection and warehousing, storage, on-site use, periodic inspection, and scrapping application. This enables intelligent identification, risk assessment, and early warning throughout the entire process, constructing a comprehensive risk management system for safety tools and equipment. It provides data support for the power safety production risk control platform, reduces workload and increases efficiency for work teams, identifies typical operational risks based on professional characteristics and work realities, implements targeted preventative measures, controls typical operational violations, misoperations, personal injury, and other safety risks, and improves safety assurance throughout the entire operational process.

[0128] In summary, the testing device and system provided in this embodiment of the invention utilize Internet of Things (IoT) technology and remote communication technology to achieve remote testing. Testing personnel can issue commands directly from elsewhere to remotely control the on-site testing equipment and observe its operation remotely via video. After testing, data is transmitted back to the central laboratory in real time for analysis and judgment by testing personnel to meet customers' rapid needs. Simultaneously, remote control significantly saves testing personnel's time; on-site personnel only need to perform simple installation and wiring, with all operations controlled by commands issued from the central laboratory, reducing the possibility of human error in intermediate stages.

[0129] This testing device is of great significance to the traditional insulation tool testing industry. Firstly, it significantly reduces the costs associated with round-trip testing (such as vehicle usage fees and paper waste), and avoids problems such as insufficient utilization, inadequate overall planning and utilization, fragmented structure, and low efficiency associated with traditional testing equipment. Compared to the size and footprint of traditional testing equipment, this device is simple in structure, portable, and has a more rational design, making it more suitable for on-site testing of small batches of insulation safety protection tools.

[0130] The device utilizes 5G IoT technology, making it easy to manage and maintain, effectively reducing deployment costs. It helps users build a digital IoT network, integrating people with physical systems. Within this integrated network, a powerful central computer cluster enables real-time management and control of metrology personnel, machines, equipment, and infrastructure. Based on this, production and daily life can be managed in a more refined and dynamic way, achieving a "smart" state, improving resource utilization and productivity, and enhancing the relationship between people and equipment. The project's research can also be gradually extended to the entire metrology industry. Scientifically and systematically organizing the collected data, and managing it as a resource, will bring immeasurable benefits to customers and society.
