Description

Technical Field

[0001] The invention relates to the technical field of turn-adjustable arc-extinguishing coils, and in particular to a turn-adjustable arc-extinguishing coil device and a complete set of turn-adjustable arc-extinguishing coils. Background Art

[0002] Since the arc extinguishing performance of the turn-adjustable arc extinguishing coil device has the advantage of flexible adjustment and can cope with various types of grounding faults, it is widely favored. Since the turn-adjustable arc extinguishing coil device is mostly used in high-voltage places (such as 6.3kV distribution network), the arc extinguishing coil, transformer, etc. inside the device will generate a lot of heat energy when performing arc extinguishing work, resulting in a high temperature in the cabinet. In order to avoid excessive temperature in the cabinet, the existing turn-adjustable arc extinguishing coil device usually has ventilation holes for fanning heat. However, in the related technology, it is ignored that after the cabinet door is opened, the cabinet door and the ventilation holes will form air convection, resulting in a large amount of pollutants (such as conductive dust, water vapor, etc.) infiltration after the cabinet door is opened. Taking water vapor as an example, the intrusion of water vapor will cause a sharp increase in the air humidity in the cabinet, which will not only increase the risk of leakage, but also accelerate the metal corrosion of the equipment in the cabinet, affecting the performance of the turn-adjustable arc extinguishing coil device.

[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0030] In the following description, it is necessary to understand that the directions or positional relationships indicated by “front”, “back”, “up”, “down”, “left”, “right”, “longitudinal”, “horizontal”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “head”, and “tail”, etc., are based on the directions or positional relationships shown in the accompanying drawings, and are constructed and operated in a specific direction. They are only for the convenience of describing the technical solution, and do not indicate that the device or element referred to must have a specific direction. Therefore, they should not be understood as limiting the present invention.

[0031] The present invention provides a complete set of turn-adjustable arc-extinguishing coils, which can accommodate the turn-adjustable arc-extinguishing coils and equipment related to arc-extinguishing work (such as transformers, terminal boxes, lightning arresters, and arc-extinguishing components, etc.), and when the device is turned on, it can reduce the pollution of conductive dust and water vapor to the cabinet equipment in the complete set (including arc-extinguishing coils, lightning arresters, arc-extinguishing components, transformers, etc.), which helps to improve the reliability of the equipment in the cabinet. Figures 1 to 6 As shown, the complete set of the turn-adjustable arc-extinguishing coil may include a cabinet 1 and a longitudinal partition plate 2 arranged in the cavity of the cabinet 1.

[0032] See also Figures 1 to 3The cabinet 1 can be in the shape of a rectangular parallelepiped, and the cabinet 1 includes a top wall 101, a bottom wall (not marked) opposite to the top wall 101, two first side walls 102 opposite to each other, and a second side wall (not marked) connected to the top wall 101, the bottom wall and the two first side walls 102, so as to form a cavity with an opening in the cabinet 1.

[0033] For ease of understanding, the present invention defines the direction parallel to the first side wall 102 as the longitudinal direction, and the direction parallel to the first side wall 102 as the transverse direction (ie, the horizontal direction).

[0034] See also Figures 1 to 3 , the longitudinal partition plate 2 is arranged longitudinally in the cavity to divide the cavity longitudinally to form two receiving compartments 3 that can respectively accommodate the arc extinguishing coil 40 and the transformer 50. It can be understood that the longitudinal partition plate 2 can divide the space inside the cabinet 1 into two receiving compartments 3. Since the arc extinguishing coil 40 and the transformer 50 will generate a magnetic field when working, the work may affect each other, and the longitudinal partition plate 2 can isolate the two to avoid the two affecting each other when working. In addition, the longitudinal partition plate 2 can be an integrated structure with the cabinet 1 to improve the overall strength of the cabinet 1. Accordingly, the cabinet 1 is preferably made of metal to obtain a better shielding effect and further improve the reliability of the cabinet 1.

[0035] A ventilation hole 4 communicating with the outside is provided on the outer wall of each receiving bin 3 , wherein the outer wall of one receiving bin 3 corresponds to one of the first side walls 102 of the cabinet 1 , and the outer wall of another receiving bin 3 corresponds to the other first side wall 102 of the cabinet 1 .

[0036] The opening of each receiving bin 3 is rotatably connected with a door leaf assembly 5 which can be opened and closed thereon, and when the door leaf assembly 5 is closed, the receiving bin 3 connected thereto can be sealed. The door leaf assembly 5 can be connected to the outer side wall of the corresponding receiving bin 3 in a hinged manner.

[0037] A heat dissipation component 6 is provided on each door leaf component 5, and the heat dissipation component 6 cooperates with the ventilation hole 4 to form convection in each receiving bin 3, thereby dissipating heat for the equipment in the receiving bin 3 by air cooling.

[0038] Each receiving bin 3 is also provided with a sealing mechanism 7 corresponding to the ventilation holes 4 on the outer wall of the receiving bin 3 and a moving rod 8 rotatably connected between the sealing mechanism 7 and the door leaf assembly 5 of each receiving bin 3. When a door leaf assembly 5 is opened, the moving rod 8 connected thereto is driven to drive the sealing mechanism 7 connected to the moving rod 8 to close the corresponding ventilation hole 4; when a door leaf assembly 5 is closed, the moving rod 8 connected thereto is driven to drive the sealing mechanism 7 connected to the moving rod 8 to open the corresponding ventilation hole 4.

[0039] It can be understood that the present invention can drive the sealing mechanism 7 to close the ventilation hole 4 when the staff opens the door leaf assembly 5, so that the door leaf opening cannot form air convection with the ventilation hole 4, and the external air cannot quickly enter the interior of the cabinet, so that dust and water vapor in the air cannot enter the cabinet, and after the door leaf assembly 5 is closed, the heat dissipation assembly 6 cooperates with the ventilation hole 4 to dissipate heat for the equipment in the cabinet, thereby preventing the equipment in the cabinet from being damaged due to excessive temperature, and effectively improving the reliability of the equipment in the cabinet.

[0040] In some embodiments, Figure 4 and Figure 5 As shown, each sealing mechanism 7 may include a sliding groove 71, a sealing plate 72 that is slidably connected to the sliding groove 71 and is arranged parallel to the outer wall of the receiving bin 3 where the sliding groove 71 is located, a meshing assembly 73 that is arranged on the sealing plate 72, and a transmission assembly 74 that is meshed and connected to the meshing assembly 73 and is rotatably connected to the moving rod 8. When the door leaf assembly 5 is opened or closed, the moving rod 8 is pulled or pushed to move horizontally, and the lateral displacement of the moving rod 8 causes the transmission assembly 74 to drive the meshing assembly 73 to move longitudinally, thereby driving the sealing plate 72 to move longitudinally on the sliding groove 71. Specifically, when the door leaf assembly 5 is opened, it will pull the moving rod 8 to move laterally in the opening direction of the receiving bin 3, causing the transmission assembly 74 to drive the sealing plate 72 to move longitudinally downward. When the door leaf assembly 5 is opened to a degree greater than a certain angle, the sealing plate 72 will completely close the ventilation hole 4. When the door leaf assembly 5 is closed, it will push the moving rod 8 to move laterally away from the opening direction of the receiving bin 3, causing the moving rod 8 and the sealing plate 72 to move longitudinally upward. After the degree is less than a certain angle, the ventilation hole 4 is fully opened.

[0041] In some embodiments, Figure 5 As shown, each engagement assembly 73 includes two tooth plates 731 respectively mounted on the two longitudinal side walls of the sealing plate 72. Specifically, the sealing plate 72 may be a rectangular parallelepiped structural plate, the two longitudinal side walls of the sealing plate 72 correspond to the two side walls perpendicular to the outer side wall of the receiving bin 3 and the bottom wall of the cabinet 1, and the tooth plates 731 are fixedly mounted one-to-one on the two longitudinal side walls of the sealing plate 72. Of course, the engagement assembly 73 may also be fixed on the side wall of the sealing plate 72 opposite to the outer side wall of the receiving bin 3, as long as it does not affect the sealing performance of the sealing plate 72 after closing the ventilation hole 4.

[0042] Accordingly, see Figure 5Each transmission assembly 74 may include a transmission member 741 fixed in the receiving bin 3 and rotatably connected to the moving rod 8, a linkage gear set 742 rotatably connected to the transmission member 741, two driving members 743 rotatably connected to the linkage gear set 742 through a transmission chain, and two driving gears 744 connected to the two driving members 743 in a one-to-one correspondence and meshed with the two tooth plates 731 in a one-to-one correspondence. When the moving rod 8 is displaced laterally, the linkage gear set 742 is driven to rotate by driving the transmission member 741, which drives the two driving members 743 to rotate in opposite directions, drives the driving gear 744 to rotate, and then drives the two tooth plates 731 to longitudinally displace in the same direction. Among them, the transmission chain can be a belt; and the linkage gear set 742 can be an existing planetary gear set, which can simultaneously drive the two groups of belts rotatably connected to the driving member 743 to rotate in opposite directions when rotating.

[0043] In some embodiments, Figure 5 and Figure 6 As shown, each transmission member 741 may include a sliding guide rail 7411, a mounting block 7412 that is slidably connected to the sliding guide rail 7411 and is rotatably connected to the pin of the moving rod 8, a driving tooth plate 7413 connected to the mounting block 7412, a driving gear 7414 that is rotatably connected to the sliding guide rail 7411 and meshed with the driving tooth plate 7413, and a transmission gear 7415 that meshes with the driving gear 7414 and is rigidly connected to the linkage gear set 742. When the moving rod 8 is displaced laterally, the mounting block 7412 is driven to slide laterally on the sliding guide rail 7411, thereby pulling or pushing the driving tooth plate 7413 to slide laterally on the sliding guide rail 7411 along with the mounting block 7412. Since the driving tooth plate 7413 meshes with the driving gear 7414, it will drive the driving gear 7414 to rotate, and the rotation of the driving gear 7414 will drive the transmission gear 7415 to rotate in the opposite direction, thereby driving the linkage gear set 742 to rotate.

[0044] In some embodiments, each transmission member 741 may also include a rigid transmission gear 7416 rigidly connected to the driving gear 7414. The rigid transmission gear 7416 is meshingly connected to the transmission gear 7415. When the driving gear 7414 rotates, it will drive the rigid transmission gear 7416 to rotate, thereby driving the transmission gear 7415 to rotate.

[0045] In some embodiments, Figure 5As shown, each sliding guide rail 7411 may include a fixed plate 7410 fixed on the outer side wall of the receiving bin 3, and the two lateral end faces of the fixed plate 7410 extend the first extension plate 7420 and the second delay plate 7430 respectively in the direction away from the first side wall 102 of the cabinet 1, and the longitudinal end face away from the opening of the receiving bin 3 extends the third extension plate 7440 connected with the first extension plate 7420 and the second delay plate 7430 to form an inner cavity, wherein the third extension plate 7440 plays a reinforcing role. The driving gear 7414 is arranged in the inner cavity and is rotatably connected to the fixed plate 7410, and the transmission gear 7415 is rigidly connected to the linkage gear set 742 and then passes through the fixed plate 7410 and is rotatably connected to the fixed plate 7410, wherein the transmission gear 7415 is located in the inner cavity and the linkage gear set 742 is located outside the inner cavity.

[0046] In some embodiments, Figure 3 As shown, the complete set of devices also includes a transverse partition plate 70 disposed in the cavity and close to the top wall 101 of the cabinet 1, so as to define each receiving compartment 3 as a top compartment 31 for receiving a terminal box 20 that can be connected to the power distribution monitoring system and a bottom compartment 32 for receiving an arc extinguishing coil 40 or a transformer 50. A through groove is further provided at the junction of the transverse partition plate 70 and the two first side walls 102, through which the sealing plate 72 can pass.

[0047] It should be noted that the advantage of the turn-adjustable arc-extinguishing coil is that the arc-extinguishing effect can be adjusted by adjusting the number of turns of the arc-extinguishing coil, so that a good arc-extinguishing effect can be obtained under different ground faults. The function of the terminal box 20 is to enable the equipment in the cabinet to be connected to the power distribution monitoring system to obtain the ground fault situation in real time, such as the ground fault current, the ground fault voltage, etc., so as to achieve turn adjustment based on the ground fault current and the ground fault voltage.

[0048] In some embodiments, Figure 2 As shown, each door leaf assembly 5 may include a first door leaf 51 and a second door leaf 52 that can be opened and closed on the top chamber 31 and the bottom chamber 32 of the receiving bin 3 connected thereto, respectively, so that the staff can open the first door leaf 51 or the second door leaf 52 separately according to the needs, thereby reducing the risk of pollution from external conductive dust and water vapor. At least one heat dissipation hole 53 is provided on each first door leaf 51 and each second door leaf 52 to increase the heat dissipation effect. An observation window 54 is also provided on each second door leaf 52 to facilitate the staff to observe the situation of the bottom chamber 32 without opening the second door leaf 52. It should be noted that the moving rod 8 is rotatably connected between the second door leaf 52 and the mounting block 7412 in the sealing mechanism 7.

[0049] In some embodiments, Figure 1As shown, each heat dissipation assembly 6 may include a fan 61 disposed on the second door leaf 52, and the fan 61 is started when the door leaf assembly 5 is closed or the temperature in the bin is greater than the set temperature. Accordingly, each heat dissipation assembly 6 may also include a temperature sensor capable of measuring the temperature of the bottom bin 32 (i.e., the temperature in the bin) and a driver electrically connected to the temperature sensor and the fan 61, and the driver is used to control the fan 61 to start when the temperature in the bin is greater than the set temperature.

[0050] In some embodiments, Figure 2 As shown, the complete set of equipment also includes a plurality of grounding members 9 disposed on the bottom wall of the cabinet 1 for grounding, and a lighting assembly 10 disposed on the top wall 101 of the cabinet 1 for illuminating each storage bin 3 .

[0051] It should be noted that in the present invention, the rotational connection can be achieved through existing bearings.

[0052] It can be understood that the technical solution of the present invention cooperates with the door leaf assembly, the movable rod and the sealing mechanism to close the ventilation holes through the sealing mechanism when the door leaf assembly is opened, so as to avoid air convection between the ventilation holes and the door leaf assembly after the door leaf assembly is opened, so as to prevent the external air from quickly entering the cabinet body, and to prevent dust and water vapor in the air from entering the cabinet body, thereby avoiding affecting the performance of the equipment in the cabinet. The ventilation holes are also opened when the door leaf assembly is closed, so as to ensure the heat dissipation effect and avoid overheating and damage of the cabinet equipment.

[0053] The present invention further provides a turn-adjustable arc-extinguishing coil device, comprising an arc-extinguishing coil 40, a transformer 50 and a complete set of the turn-adjustable arc-extinguishing coil provided in an embodiment of the present invention.

[0054] In some embodiments, Figure 3 As shown, the turn-adjustable arc extinguishing coil device may also include a terminal box 20 disposed in the receiving chamber 3 and a lightning arrester 30 and an arc extinguishing assembly 60 disposed in the receiving chamber 3 where the arc extinguishing coil 40 is located. The functions of the arc extinguishing coil 40, the transformer 50, the lightning arrester 30 and the arc extinguishing assembly 60 can refer to the working principle of the existing turn-adjustable arc extinguishing coil, which will not be repeated here.

[0055] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
