Description

Technical Field

[0001] This invention belongs to the field of electrical testing technology, and in particular relates to a method for electrical testing of insulating blankets at construction sites without power outages. Background Technology

[0002] Before live-line work on power distribution networks, electrical performance tests must be performed on all insulated equipment used. Insulating blankets are used extensively, and according to safety regulations, interlayer electrical testing of the insulating blankets is required to prevent electrical breakdown hazards caused by interlayer perforations. In actual work sites, the inspection typically only checks the cleanliness of the insulating blankets or uses conventional electrical testing instruments to check the surface insulation resistance. Therefore, conventional testing methods are time-consuming and ineffective, and they do not perform perforation testing on the insulating blankets, creating potential safety hazards. Currently, the main testing method involves manual handling, feeding, and testing, which involves close proximity to electrodes and poses a risk of electric shock. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of existing detection methods, such as long detection time and inability to effectively detect perforations and potential safety hazards. This invention innovatively employs technologies such as automated detection, wireless data communication, and database management to achieve automatic detection, automatic zoning and stacking of insulating blankets, and data storage, display, and callback.

[0004] To achieve the objective of this invention, a method for electrical testing of insulating blankets at construction sites without power interruption is disclosed, comprising the following steps:

[0005] Step 1: The controller identifies the insulation blanket information through the walking component and takes the insulation blanket to be tested out of the insulation blanket pile, and transports the insulation blanket to be tested to the testing station;

[0006] Step 2: After the insulation blanket is tested at the testing station, the current sensor at the testing station uploads the test results to the controller.

[0007] Step 3: After receiving the test results, the controller uploads the insulation blanket information and the corresponding test results to the database of the management system.

[0008] Step 4: Based on the test results, the controller uses the walking component to place the tested insulation blankets into the qualified or unqualified product pile.

[0009] Furthermore, the specific steps of step 1 are as follows:

[0010] Step 1-1: Affix a QR code to the edge of each insulating blanket. The QR code is generated and recorded by the management system.

[0011] Steps 1-2: The QR code scanner is fixedly connected to the walking component. Each time the controller controls the walking component to reach the scanning position, the QR code scanner scans the QR code, obtains the QR code information of the insulating blanket, and sends it to the controller.

[0012] Steps 1-3: The controller controls the walking component to reach the top of the insulating blanket stack, controls the cylinder of the walking component to lower the suction cup, picks up an insulating blanket, lifts it up and transports it to the inspection station.

[0013] Furthermore, the specific steps of step 2 are as follows:

[0014] Step 2-1: The controller controls the walking component to move above the testing station and controls the cylinder of the walking component to descend so that the lower side of the insulating blanket fully contacts the testing station platform. At this time, the platform serves as a high-voltage testing electrode, and the suction cup on the walking component that picks up the insulating blanket serves as another testing electrode for grounding.

[0015] Step 2-2: The controller pressurizes the high-voltage electrode on the control panel. After a preset time, it collects the current transformer data of the high-voltage electrode of the transformer, makes a judgment, and obtains the detection result.

[0016] Further, step 3 specifically involves the controller binding the detection results with the insulation blanket information obtained in step 1 after obtaining the detection results, and uploading it to the remote database of the management system via the 4G module.

[0017] Furthermore, step 4 consists of the following specific steps:

[0018] Step 4-1: The controller sends control commands to the walking component based on the detection results;

[0019] Step 4-2: According to the control command, the walking component uses a cylinder to control the suction cup to lift the insulating blanket and transport it to the top of the qualified product pile and the unqualified product pile.

[0020] Step 4-3: The suction cup releases the insulating blanket, which falls into the corresponding qualified or unqualified product pile.

[0021] Furthermore, the walking assembly includes a suction cup, a suction nozzle, an electric cylinder, and a linear module; the linear module slider drives the electric cylinder to move back and forth, and the electric cylinder extension rod is connected to the suction cup to drive the suction cup to move up and down; the electric cylinder is equipped with a limit switch to determine the electric cylinder's walking position; four suction nozzles are fixed at the four corners of the suction cup to pick up insulating blankets; the QR code scanner is fixedly connected to the walking assembly, and the QR code scanner is electrically connected to the controller.

[0022] Furthermore, the controller is a PLC touch screen all-in-one machine, used to process high-voltage current data to determine whether the test is qualified; and to control the electric cylinder and stepper motor to perform the required directional movements; the touch screen is used to display the operating status, control the start and stop of the equipment, and input the necessary parameters of the equipment.

[0023] Furthermore, the information on the insulating blankets includes the blanket number and the date of inspection.

[0024] Furthermore, the management system is used to manage the inspection records of each insulating blanket. By identifying the test results through QR code recognition, the system binds the qualified insulating blankets. When a user uses an insulating blanket, they can scan the QR code on the insulating blanket to display the insulating blanket number, inspection date, and inspection results.

[0025] To achieve the objectives of this invention, this invention also discloses an electrical testing system for insulation blankets at construction sites without power outages, including a controller, a walking component, and a management system.

[0026] Compared with existing technologies, the significant advancements of this invention are: 1) Intelligent detection using the equipment of this invention improves the efficiency and accuracy of insulating blanket detection; 2) It greatly enhances the safety of power field operations, eliminates safety hazards, and is suitable for widespread promotion and application; 3) It facilitates information management, enabling real-time information display, information recall, and querying of past insulating blanket information, reducing the possibility of repeated detection. It records the expiration date of each insulating blanket and provides reminders for near-expiration detection.

[0032] like Figure 1 As shown, a method for electrical testing of insulation blankets at a live-line construction site includes the following steps:

[0033] Step 1: The controller identifies the insulation blanket information through the walking component and takes the insulation blanket to be tested out of the insulation blanket pile, and transports the insulation blanket to be tested to the testing station;

[0034] Step 2: After the insulation blanket is tested at the testing station, the current sensor at the testing station uploads the test results to the controller.

[0035] Step 3: After receiving the test results, the controller uploads the insulation blanket information and the corresponding test results to the database of the management system.

[0036] Step 4: Based on the test results, the controller uses the walking component to place the tested insulation blankets into the qualified or unqualified product pile.

[0037] refer to Figure 2 Furthermore, the specific steps of step 1 are as follows:

[0038] Step 1-1: Affix a QR code to the edge of each insulating blanket. The QR code is generated and recorded by the management system.

[0039] Steps 1-2: The QR code scanner is fixedly connected to the walking component. Each time the controller controls the walking component to reach the scanning position, the QR code scanner scans the QR code, obtains the QR code information of the insulating blanket, and sends it to the controller.

[0040] Steps 1-3: The controller controls the walking component to reach the top of the insulating blanket stack, controls the cylinder of the walking component to lower the suction cup, picks up an insulating blanket, lifts it up and transports it to the inspection station.

[0041] Furthermore, the specific steps of step 2 are as follows:

[0042] Step 2-1: The controller controls the walking component to move above the testing station and controls the cylinder of the walking component to descend so that the lower side of the insulating blanket fully contacts the testing station platform. At this time, the platform serves as a high-voltage testing electrode, and the suction cup on the walking component that picks up the insulating blanket serves as another testing electrode for grounding.

[0043] Step 2-2: The controller pressurizes the high-voltage electrode on the control panel. After a preset time, it collects the current transformer data of the high-voltage electrode of the transformer, makes a judgment, and obtains the detection result.

[0044] Further, step 3 specifically involves the controller binding the detection results with the insulation blanket information obtained in step 1 after obtaining the detection results, and uploading it to the remote database of the management system via the 4G module.

[0045] Furthermore, step 4 consists of the following specific steps:

[0046] Step 4-1: The controller sends control commands to the walking component based on the detection results;

[0047] Step 4-2: According to the control command, the walking component uses a cylinder to control the suction cup to lift the insulating blanket and transport it to the top of the qualified product pile and the unqualified product pile.

[0048] Step 4-3: The suction cup releases the insulating blanket, which falls into the corresponding qualified or unqualified product pile.

[0049] Furthermore, the walking component includes a suction cup, a cylinder, and a linear module; the QR code scanner is fixedly connected to the walking component and electrically connected to the controller.

[0050] Furthermore, the controller is an embedded system or a PLC.

[0051] Furthermore, the information on the insulating blankets includes the blanket number and the date of inspection.

[0052] Furthermore, the management system is used to manage the inspection records of each insulating blanket; when a user uses an insulating blanket, they scan the QR code on the insulating blanket to display the insulating blanket number, inspection date, and inspection results.

[0053] Specifically, in this embodiment, the controller uses a Yoko PLC touch screen all-in-one machine, the management system is based on a B / S architecture, and the barcode scanner uses a Mindray intelligent barcode scanner. The walking component uses a Pfide 57 stepper motor to drive a linear module, and an Yixing electric push-pull rod. The suction cup and other components are non-standard customized.

[0054] Specifically, in this embodiment, a servo motor drives a linear motion module to move a suction cup bracket and a vacuum suction cup to pick up the insulating blanket to be tested from the material to be tested position. It is then moved to the high-voltage electrode testing position for testing. If the test is successful, it moves to the successful position where the vacuum environment in the vacuum conduit and suction cup is broken, and the insulating blanket is released. If the test is unsuccessful, it moves to the unsuccessful position where the vacuum negative pressure in the vacuum conduit and vacuum suction cup is broken, and the insulating blanket is released. Then, the material picking and testing process is repeated.

[0055] Specifically, in this embodiment, the electrode pressurization principle is as follows: the conversion of household 220V AC power to 50kV high voltage is mainly achieved by a 50kV step-up transformer. The primary coil and secondary coil of the 50kV step-up transformer have a fixed ratio of 200:50000.

[0056] Specifically, in this embodiment, the implementation steps are as follows: A current relay is connected in series with the 220V neutral wire of a household appliance to trip the circuit breaker promptly after the insulation blanket is broken down. The output of the current relay and the 220V live wire are connected to the primary winding of a 0-220V electrically adjustable transformer. The transformer's regulating motor is controlled by a PLC controller. The secondary winding of the transformer is connected to the primary winding of a 50kV step-up transformer. The secondary high-voltage winding of the 50kV transformer is connected to the high-voltage detection plate (detection workbench), and the suction cup end is grounded. This achieves high-voltage detection of the insulation blanket between the high-voltage plate and the ground plate. If the current relay does not disconnect after the high voltage is applied, the detection is qualified; otherwise, the detection is unqualified.
