Description

Technical Field

[0001] The utility model relates to the field of distribution cabinet door locks, and more specifically, to a supporting insulating cabinet for a high-voltage live electrical inspection device. Background Technique

[0002] The supporting insulating cabinet is a type of ring main unit distribution cabinet, mainly used to install and protect electrical equipment related to power distribution and power transmission lines. In order to improve the safety of using this type of cabinet, an electrical inspection device is generally installed on the cabinet to prevent the cabinet shell from being electrified due to internal circuit leakage of the cabinet, and to avoid the danger of electric shock when personnel touch it.

[0003] According to the usage habits of staff, when generally overhauling the electrical equipment inside the cabinet, they usually first contact the door lock mechanism to unlock the door lock, and then open the cabinet door. However, the existing electrical inspection device lacks an electrical inspection mechanism for the door lock, so it is not very convenient for staff to judge whether the cabinet shell is electrified at the moment of contacting the door lock mechanism, affecting the safety of use. Therefore, we propose a supporting insulating cabinet for a high-voltage live electrical inspection device to solve the above existing problems. Content of the Utility Model

It is provided with a transparent shell on the door lock mechanism, and a first conductive copper sheet, a second conductive copper sheet, a resistor body and a neon bulb are installed inside the transparent shell. When the staff presses the unlocking button by pressing the elastic piece, the transparent shell can be squeezed inward, prompting the conductive column to move into the conductive pipe column and contact the inner bottom of the conductive pipe column. At this time, when the cabinet body and the cabinet door are electrified, the current can be conducted from the lock tongue piece in contact with the cabinet door to the inside of the wire, and then from the wire through the conductive pipe column, the conductive column and the first conductive copper sheet to the resistor body and the neon bulb. And since the other end of the neon bulb is in contact with the human body through the second conductive copper sheet, the conductive nut and the elastic piece, and the human body is in contact with the ground, the neon bulb can be instantly lit, so as to remind the staff whether the cabinet body or the cabinet door is electrified at the moment of pressing the door lock mechanism to unlock, improving the safety of use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1:

[0028] Please refer to Figures 1-6 , a supporting insulating cabinet for a high-voltage live electrical inspection device, including a cabinet body 1 and a cabinet door 2. The cabinet door 2 is rotatably connected to one side of the cabinet body 1. A lock hole is opened on one side of the edge of the cabinet body 1, and a door lock mechanism 3 is fixedly installed inside the lock hole. A limiting angle member 4 is fixedly installed on the inner wall of the cabinet door 2 corresponding to the position of the door lock mechanism 3;

[0029] The door lock mechanism 3 includes a mounting plate 5 fixedly installed on one side of the lock hole. A lock tongue piece 501 is arranged on one side of the top of the mounting plate 5. The lock tongue piece 501 is in contact with the gap between the cabinet door 2 and the limiting angle member 4, and an unlocking button 502 is also arranged on the mounting plate 5;

[0030] One side of the bottom inside the mounting plate 5 is fixedly installed with a conductive pipe column 6. The conductive pipe column 6 is connected to the lock tongue piece 501 through a wire 7. A transparent shell 8 is arranged on the bottom of the outer wall of the mounting plate 5. A conductive column 9 is fixedly installed on one side of the transparent shell 8. The conductive column 9 is slidably connected inside the conductive pipe column 6, and a plastic spring 901 is sleeved outside the conductive column 9. A group of sliding holes 503 are also opened on the mounting plate 5. A limiting pile 801 is slidably connected inside the group of sliding holes 503, and the group of limiting piles 801 are fixedly welded on one side of the transparent shell 8;

[0031] A conductive nut 10 is threadedly connected to the other side of the transparent shell 8, and a pressing elastic piece 1001 is fixedly connected to the conductive nut 10. One end of the pressing elastic piece 1001 extends to the top of the unlocking button 502. A conductive copper sheet one 11 and a conductive copper sheet two 12 are fixedly installed inside the transparent shell 8. The conductive copper sheet one 11 and the conductive copper sheet two 12 are not in contact with each other. One side of the conductive copper sheet one 11 is in contact with one end of the conductive column 9. One end of the conductive copper sheet two 12 is in contact with one side of the inner wall of the conductive nut 10. A support spring 13 is fixedly welded on one side of the inner wall of the conductive copper sheet two 12, and a resistor body 14 and a neon bulb 15 are clamped between the conductive copper sheet one 11 and the conductive copper sheet two 12 through the support spring 13.

[0032] The electrical inspection principle of this supporting insulating cabinet for a high-voltage live electrical inspection device is as follows:

[0033] When the inside of the cabinet body 1 is electrified due to circuit leakage, causing the cabinet door 2 and the cabinet body 1 to be electrified, and the staff needs to perform maintenance on the inside of the cabinet body 1, first, the staff's finger touches and presses the pressing elastic piece 1001, forcing the unlocking button 502 to be pressed through the pressing of the pressing elastic piece 1001, facilitating the unlocking process (the unlocking principle and lock body structure of this kind of door lock mechanism are already known public technologies, so no detailed description will be given here). At the moment of pressing and contacting the unlocking button, the transparent outer shell 8 can be squeezed inward, prompting the conductive column 9 to move into the conductive tube column 6 and contact the bottom inner wall of the conductive tube column 6. At this time, when the cabinet body 1 and the cabinet door 2 are electrified, and the lock tongue piece 501 is in contact with the cabinet door 2 or the limit angle piece 4, the current can be conducted through the lock tongue piece 501 into the wire 7, and then from the wire 7 through the conductive tube column 6, the conductive column 9, and the first conductive copper sheet 11 and conduct to the resistor body 14 and the neon bulb 15. Also, since the other end of the neon bulb 15 is in contact with the staff's finger through the support spring 13, the conductive copper sheet 12, the conductive nut 10, and the pressing elastic piece 1001, and the staff is in contact with the ground, the neon bulb 15 can be instantly lit, so as to remind the staff that the cabinet body 1 or the cabinet door 2 is in an electrified state at the moment of pressing the door lock mechanism 3 to unlock, achieving a warning effect and improving the safety of use;

[0034] Based on the above, if the neon bulb 15 does not light up when the staff presses to unlock and open the door, it means that no current is conducted through the lock tongue piece 501 into the transparent outer shell 8. At this time, it can be known that the cabinet body 1 or the cabinet door 2 is not electrified, improving the safety during maintenance.

[0035] Embodiment 2:

[0036] In view of the above Embodiment 1, for further description, refer to Figure 5 and Figure 6 There is a concave limiting area on the resistor body 14, and one end of the neon bulb 15 is in contact with the resistor body 14 through the concave limiting area.

[0037] Through the structures of the resistor body 14, the neon bulb 15, the first conductive copper sheet 11, and the second conductive copper sheet 12, the principle similar to that of a test pen can be realized, facilitating testing. Among them, the setting of the first conductive copper sheet 11 and the second conductive copper sheet 12 plays the role of connecting the circuit of the conductive column 9 and the conductive nut 10. The setting of the plastic spring 901 can not only facilitate the outward reset of the conductive column 9 when it is not under pressing force later, but also make the contact part between the outer wall of the conductive column 9 and the inner wall of the conductive tube column 6 achieve insulating contact. The setting of the limit post 801 plays the role of installing the transparent outer shell 8 and does not interfere with the movement of the transparent outer shell 8.

[0038] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved conceptions, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present utility model.
