Description
Technical Field
[0001] The utility model relates to the field of electric high-voltage cabinets, in particular to a switch structure of an electric high-voltage cabinet. Background Art
[0002] Electric high-voltage cabinets are used for switching, controlling or protecting in the power generation, transmission, distribution, energy conversion and consumption of power systems. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry and occupies a very important position in the entire power industry.
[0003] Metal armored fixed high-voltage power cabinets can have better protection when used outdoors. The compartments are equipped with metal partitions, which can limit the fault arc to the compartment where it is generated. Once the arc touches the metal partition, it will be introduced into the ground. It has good safety and easy replacement of circuit breakers.
[0004] However, when the existing high-voltage power cabinet is in use, the switch structure of its external cabinet body often adopts door panel rotation, and then the two door panels are fixed with locks. In this type of fixing method, the fixing point is often located in the middle of the door panel. When encountering problems such as strong wind or vibration, the door panel as a whole only relies on the fixing point in the middle for stability. This leads to insufficient stability of the door panel in some cases, resulting in shaking, thereby reducing the service life of the switch structure, and the stability of the switch structure will continue to decrease. Utility Model Content

[0009] By adopting the above technical solution, by setting the socket and the plug block, the push rod can be fixed, so that the whole can be made more stable. By setting the fixing rod, the movement of the plug block is limited by the fixing rod, avoiding the problem that the plug block is offset during the movement, thereby preventing the push rod from being fixed.

[0013] By adopting the above technical solution and setting a pulley, the movement of the steel cable can be sufficiently stable and labor-saving, and the friction can be reduced. At the same time, the movement direction of the steel cable can be changed, making the overall operation more stable.
[0014] The utility model is further configured that rotating shafts are installed on both sides of the door panel, and the door panel is connected to the cabinet body through the rotating shaft, and a handle is fixedly installed on one side of the door panel.
[0015] By adopting the above technical solution and providing the handle, there are sufficient force points during the process of moving the door panel, which makes it more convenient to operate the movement of the door panel.
[0016] In summary, the utility model mainly has the following beneficial effects:

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0024] The following describes an embodiment of the utility model based on its overall structure.
[0025] A power high voltage cabinet switch structure, such as Figure 1-4 As shown, it includes a cabinet 1, a push rod 4 is movably installed on one side of the cabinet 1, and a connecting rod 5 is fixedly installed on one end of the push rod 4, steel cables 10 are installed on both sides of the connecting rod 5, and a second connecting plate 12 is arranged at one end of the connecting rod 5, and the connecting rod 5 is connected to the second connecting plate 12 through the steel cable 10, a first connecting plate 7 is movably installed on one end of the cabinet 1, and a first plugging plate 8 is fixedly installed on one end of the first connecting plate 7, and a second plugging plate 11 is fixedly installed on one end of the second connecting plate 12, a door panel 2 is movably installed on one side of the cabinet 1, and slots 17 are provided at both ends of the door panel 2, and the push rod 4 is pushed, and the push rod 4 is displaced at this time. When the push rod 4 is displaced, it drives the connecting rod 5 to be displaced, so that the connecting rod 5 pulls the steel cable 10. At this time, under the action of the pulley 9, one end of the steel cable 10 pulls the second connecting plate 12, so that the second connecting plate 12 moves up. When the second connecting plate 12 moves up, it drives the second plugging plate 11 to move up, so that the second plugging plate 11 enters the slot 17. When the push rod 4 is displaced, it drives the arc block 15 to be displaced. At this time, the arc block 15 contacts the first connecting plate 7. Under the action of the arc block 15, the first connecting plate 7 moves downward. When the first connecting plate 7 moves downward, it drives the first plugging plate 8 to move downward, so that the first plugging plate 8 enters the slot 17.
[0026] See also Figure 3An arc block 15 is fixedly installed at one end of the push rod 4, and a socket 16 is opened at one end of the arc block 15. A fixing rod 13 is fixedly installed at one end of the cabinet 1, and a plug block 14 is movably installed at one end of the fixing rod 13. A return spring is sleeved on the outer side of the fixing rod 13, and the plug block 14 cooperates with the socket 16. By setting the socket 16 and the plug block 14, the push rod 4 can be fixed, so that the whole can be made more stable. By setting the fixing rod 13, the movement of the plug block 14 is limited by the fixing rod 13, avoiding the offset of the plug block 14 during the movement, thereby preventing the push rod 4 from being fixed.
[0027] See also Figure 2 One side of the first connecting plate 7 is arranged in an arc shape, and reset springs are installed on both sides of the first connecting plate 7, and the first connecting plate 7 is connected to the cabinet 1 through the reset spring, and a spring 6 is installed on one side of the connecting rod 5. Through the reset springs arranged on both sides of the first connecting plate 7, the first connecting plate 7 has sufficient force to reset, so as to facilitate subsequent switch operations.
[0028] See also Figure 2 Pulleys 9 are movably installed on both sides of the cabinet 1, and empty grooves matching with the steel cables 10 are opened on the outer sides of the pulleys 9. There are multiple groups of pulleys 9. By setting the pulleys 9, the movement of the steel cables 10 is sufficiently stable and labor-saving, and the friction is reduced. At the same time, the movement direction of the steel cables 10 can be changed, making the overall operation more stable.
[0029] See also Figure 1 , rotating shafts are installed on both sides of the door panel 2, and the door panel 2 is connected to the cabinet 1 through the rotating shaft. A handle 3 is fixedly installed on one side of the door panel 2. Through the set handle 3, there are enough force points in the process of moving the door panel 2, which is more convenient to operate the movement of the door panel 2.
[0030] The working principle of the utility model is: when the door panel 2 needs to be closed, the door panel 2 is rotated, and the door panel 2 rotates under the action of the rotating shaft, and the door panel 2 is completely closed;
[0031] Furthermore, when the door panel 2 is completely closed, the push rod 4 is pushed, and the push rod 4 is displaced. When the push rod 4 is displaced, the connecting rod 5 is driven to be displaced, so that the connecting rod 5 pulls the steel cable 10. At this time, under the action of the pulley 9, one end of the steel cable 10 pulls the second connecting plate 12, so that the second connecting plate 12 moves up. When the second connecting plate 12 moves up, it drives the second plugging plate 11 to move up, so that the second plugging plate 11 enters the slot 17.
[0032] Furthermore, when the push rod 4 moves, the arc block 15 is driven to move, and at this time, the arc block 15 contacts the first connecting plate 7. Under the action of the arc block 15, the first connecting plate 7 moves downward, and when the first connecting plate 7 moves downward, the first plug plate 8 is driven to move downward, so that the first plug plate 8 enters the slot 17;
[0033] Furthermore, when the push rod 4 moves, the plug block 14 contacts the end of the push rod 4. When the push rod 4 moves to a certain position, the plug block 14 loses the obstruction of the push rod 4 and enters the socket 16 under the action of the return spring, so that the push rod 4 is fixed, thereby fixing the whole. At this time, the overall switch structure is more stable.
