Description

Technical Field

[0001] This application relates to the field of high-voltage electric field measurement technology, specifically to a continuous laser testing device for high-voltage electric fields. Background Technology

[0002] With the development of science and technology, the application of electronic and electrical equipment is becoming increasingly widespread, from industrial manufacturing to the communications industry for signal transmission. From a safety perspective, the demand for electric field detection is growing across all industries, and the objectively existing electric field in the space surrounding electric charges and changing magnetic fields, as well as its influence, is becoming increasingly important.

[0003] In existing technologies, the electric field detection of high-voltage conductors is usually achieved manually. When it is necessary to detect the presence or absence of voltage on a high-voltage conductor, the inspector carries a testing tool to the testing site, stands beneath the conductor, raises the tool, and brings it into contact with the conductor. When an interaction occurs between the two, it indicates the presence of high voltage on the conductor. Therefore, this detection method not only poses significant safety hazards for inspectors but is also extremely inconvenient during the testing process. Summary of the Invention

[0004] To address the problems and deficiencies in the existing technology, this application provides a continuous laser testing device for high-voltage electric fields, which not only ensures the personal safety of the testing personnel, but also makes the testing process very convenient and fast.

[0005] To achieve the above-mentioned objectives, the technical solution of this application is as follows:

[0006] A continuous laser testing device for high-voltage electric fields includes an integrated controller, a laser controller, an industrial camera, a laser, and a reflector. The integrated controller is connected to both the laser controller and the industrial camera. The laser controller is also connected to the laser. The reflector is positioned in the direction of the laser's output light. The laser beam is reflected by the reflector and then incident on the high-voltage conductor, interacting with it. The industrial camera images the high-voltage conductor and transmits the captured image to the integrated controller.

[0007] Furthermore, the integrated controller, laser controller, industrial camera, laser, and reflector are integrated into a single housing, which has a light-transmitting aperture for the laser beam to pass through.

[0008] Furthermore, the output wavelength of the laser is 380-780nm.

[0009] Furthermore, the laser is a low-power continuous laser.

[0010] Furthermore, the field of view of the industrial camera is 60 degrees.

[0011] Furthermore, the industrial camera has a response range of 400-1100nm.

[0012] Furthermore, the industrial camera is a CCD camera.

[0013] Furthermore, the output aperture of the laser is 1-3 mm, and the divergence angle is 0.1 milliradians.

[0014] The beneficial effects of this application are:

[0015] This application provides a device for continuous laser testing of the presence or absence of an electric field in a high-voltage conductor. The various components for detecting the high-voltage electric field are integrated into a portable housing. To test for the presence or absence of the high-voltage electric field, the user holds the housing, stands at a certain distance from the high-voltage conductor, and aligns the laser beam generated by the device with the conductor to complete the test. Because this application does not require close contact with the high-voltage components, it ensures the personal safety of the testing personnel. The device has high overall safety performance and is very convenient to use. Attached Figure Description

[0020] The following specific embodiments further illustrate the technical solutions for achieving the purpose of this invention. It should be noted that the technical solutions claimed in this application include, but are not limited to, the following embodiments.

[0021] Example 1

[0022] This embodiment discloses a continuous laser testing device for high-voltage electric fields, as detailed in the attached specification. Figure 1The testing device mainly includes an integrated controller 1, a laser controller 2, an industrial camera 3, a laser 4, and a reflector 5. The integrated controller 1 is the control center of the entire device, connected to both the laser controller 2 and the industrial camera 3. It is mainly used to issue corresponding control commands, receive data transmitted from components such as the industrial camera 3, and perform data analysis on the received data. Furthermore, the laser controller 2 is also connected to the laser 4. The laser controller 2 is used to receive control signals from the integrated controller 1 and control the operation of the laser 4. Furthermore, the reflector 5 is positioned in the output light direction of the laser 4 to reflect the laser emitted by the laser 4. The beam output by the laser 4 enters the high-voltage conductor after being reflected by the reflector 5 and interacts with the high-voltage conductor. The industrial camera 3 images the high-voltage conductor and transmits the captured image to the integrated controller 1. Furthermore, the output wavelength of the laser 4 is 380-780nm. Furthermore, the response imaging range of the industrial camera 3 is 400-1000nm.

[0023] When the device is operating, the integrated controller simultaneously sends control signals to the laser controller and the industrial camera. The industrial camera and laser work synchronously. During operation, the industrial camera captures an image of the high-voltage conductor and transmits the image data to the data analysis module in the integrated controller. The laser beam emitted by the laser is reflected by a mirror in the output direction and then incident on the high-voltage conductor. The laser beam acts on the high-voltage conductor. The laser power is adjustable. When the laser power reaches a certain level, the laser beam interacts with the high-voltage conductor, generating an electric arc. The data analysis module in the integrated controller determines whether an electric arc has occurred based on the returned image data, and thus determines whether a high-voltage electric field exists on the high-voltage conductor. If an electric arc is generated by the interaction of the laser beam and the high-voltage conductor, it indicates the presence of a high-voltage electric field. If no electric arc is generated, it indicates the absence of a high-voltage electric field. When a high-voltage electric field is determined to exist, the integrated controller sends a corresponding signal to the inspection personnel.

[0024] The device described in this application ensures the personal safety of testing personnel by eliminating the need for close contact with high-voltage components when testing the electric field of high-voltage conductors. The device has high overall safety performance and is also very convenient to use.

Furthermore, the laser controller 2 is also connected to the laser 4. The laser controller 2 is used to receive control signals from the integrated controller 1 and control the operation of the laser 4. Furthermore, the reflector 5 is positioned in the output light direction of the laser 4 to reflect the laser emitted by the laser 4. The beam output by the laser 4 enters the high-voltage conductor through the reflector 5 and interacts with the high-voltage conductor. The industrial camera 3 images the high-voltage conductor and transmits the captured image to the integrated controller 1. Furthermore, the output wavelength of the laser 4 is 380-780nm.

[0031] Furthermore, the integrated controller 1, laser controller 2, industrial camera 3, laser 4, and reflector 5 are integrated into a single housing. The housing has a light-passing hole for the laser beam to pass through, and also has control keys, power switches, etc. The angle of the industrial camera is adjustable.

[0032] In this application, the integrated controller, laser controller, industrial camera, laser, and reflector used for testing high-voltage electric fields are integrated into a portable housing. The housing has a light-transmitting aperture for the laser beam to pass through. When testing the electric field, the operator holds the housing, stands at a certain distance from the high-voltage wire, controls the device, and aligns the laser beam emitted by the device with the high-voltage wire. The presence or absence of the high-voltage electric field is then determined by the detection signal emitted by the device. Because the presence or absence of the high-voltage electric field on the wire can be measured without close contact, the operator's safety is ensured. The device has high overall safety performance and is very convenient to use.
