Specific embodiments

[0022] The following will disclose multiple embodiments of the present utility model in the form of diagrams. For the sake of clarity, many physical details will be described together in the following narrative. However, it should be understood that these physical details are not used to limit the present utility model. That is to say, in some embodiments of the present utility model, these physical details are unnecessary. In addition, for the sake of simplifying the diagrams, some conventional structures and components will be shown in a simple schematic manner in the diagrams.

[0023] Please refer to Figure 1 、 Figure 3 , the partial discharge monitoring device of the dry-type transformer for offshore oil platforms of the present utility model includes a cabinet body 1, a cabinet door 2 is installed on the cabinet body 1, a lock body 3 is arranged between the cabinet door 2 and the cabinet body 1, the lock body 3 is set as a common cabinet-type electronic lock, an installation box 7 is arranged inside the cabinet body 1, a connecting piece is arranged between the installation box 7 and the cabinet body 1, a light source sensor 10 is arranged on the installation box 7, a control module 11 and a communication module 16 are arranged inside the installation box 7, and the communication module 16 is connected to a remote control terminal.

[0024] When the staff opens the lock body 3 and the cabinet door 2 in the correct way, at this time, the signal of the lock body 3 is transmitted to the control module 11, and at the same time, the light source sensor 10 senses the external light and transmits the signal to the control module 11. Although the control module 11 receives the signal of the light source sensor 10, since the lock body 3 is opened correctly, the control module 11 controls the communication module 16 not to transmit a warning signal to the remote control terminal. When the opening of the lock body 3 is incorrect, while the light source sensor 10 transmits the signal to the control module 11, the control module 11 transmits the warning signal to the control terminal through the communication module 16, which is convenient for the staff to take corresponding measures and improves the safety of the device.

[0025] As Figure 3 shown, a timing module 15 is arranged inside the installation box 7, the timing module 15 is connected to the control module 11. When the lock body 3 is opened correctly, after the control module 11 receives the signal of the light source sensor 10, it controls the timing module 15 to work. When the cabinet door 2 and the lock body 3 are not closed after reaching the preset time, at this time, the control module 11 transmits the signal to the remote control terminal through the communication module 16 for warning, so as to prevent the staff from forgetting to close the cabinet door 2.

[0026] As Figure 1 、 Figure 2 shown, the connecting member includes a slide rail 6 which is installed on the inner wall of the cabinet 1. An installation box 7 is arranged on the slide rail 6. A limiting member is arranged between the installation box 7 and the cabinet 1. Through the slide rail 6 component, the installation box 7 component can be moved on the horizontal plane, so as to adjust the position of the installation box 7. By the staff taking out the installation box 7 from the cabinet 1, it is convenient for the staff to remove the installation box 7 from the cabinet 1.

[0027] There are two slide rails 6 which are symmetrically arranged at both ends of the installation box 7. The two slide rails 6 are horizontally arranged. The two slide rails 6 support and limit both ends of the installation box 7, so as to improve the stability of the installation box 7 and reduce the shaking when the installation box 7 is moved and fixed.

[0028] A light source component 5 is installed on the inner top wall of the cabinet 1. The light source component 5 is set as a common LED lamp. A trigger 4 is arranged on the inner wall of the cabinet 1. The cabinet 1 is connected to the light source component 5. When the cabinet door 2 is opened, the trigger 4 controls the light source component 5 to work, and the light source component 5 illuminates the inside of the cabinet door 2. When the cabinet door 2 is closed, the trigger 4 controls the light source component 5 to turn off the illumination. Through the light source component 5, the light source sensor 10 can work normally at night, improving the applicable scenarios of the device.

[0029] As Figure 1 、 Figure 2 、 Figure 4 shown, the limiting member includes a fixing rod 12 which is slidably installed on the installation box 7. A limiting block 13 is arranged inside the cabinet 1. A fixing groove 14 is arranged on the limiting block 13. The fixing rod 12 is inserted into the fixing groove 14. When it is necessary to take out the installation box 7 from the cabinet 1, first drive the fixing rod 12 to move on the installation box 7 and separate it from the fixing groove 14, so as to release the fixation of the installation box 7, and then drive the installation box 7 to move. When it is necessary to fix the position of the installation box 7, align the fixing rod 12 with the fixing groove 14 and insert the fixing rod 12 into the corresponding fixing groove 14.

[0030] As Figure 3 shown, a cover plate 8 is arranged on one side of the installation box 7. The cover plate 8 is fixedly connected to the installation box 7 through a fixing bolt 9, and the light source sensor 10 is installed on the cover plate 8. By removing the fixing bolt 9 between the installation box 7 and the cover plate 8, the installation box 7 can be opened, achieving the effect of being able to overhaul and replace the internal modules of the installation box 7.

[0031] The above are only the embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
