Description

Technical Field

[0002] In the switch cabinet, 500V or less is low voltage, 3KV, 6KV, 10KV, 24KV, 35KV and 66KV are medium and high voltage. KYN28-12 and KYN61-40.5 are commonly used in high-voltage distribution cabinets. In the KYN28-12 removable AC metal distribution cabinet, the circuit breaker is set on a push-pull trolley, and the circuit breaker is moved by manual push-pull. In order to facilitate the use and operation, the push-pull trolley is replaced with a mobile module in some models, and the mobile module drives the circuit breaker to move forward and backward, saving working time during operation and improving efficiency.

[0003] However, in actual use, it was found that the screw module would make a lot of noise when working, affecting the working environment. In addition, the weight of the circuit breaker would press on the screw module, which would easily deform slightly after long-term use, causing the circuit breaker to be unable to enter the predetermined position when moving, and thus making the circuit breaker unable to enter the working state. In addition, the entire circuit breaker needs to be disassembled to repair the screw module, and the circuit breaker needs to be adjusted after replacement, which affects the use of the switch cabinet.

[0048] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0049] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0050] Reference Figure 1-6 A swing-in moving mechanism for a circuit breaker of a high-voltage switch cabinet in this embodiment is described.

[0051] The high-voltage switch cabinet is an intelligent KYN28-12 switch cabinet, including a cabinet body 1, which includes a top compartment, a middle compartment 3 and a bottom compartment. The middle compartment 3 and the bottom compartment are separated by a middle compartment bottom plate 4. A circuit breaker 2 is arranged on the middle compartment bottom plate 4. The circuit breaker is a solid-sealed pole type intelligent circuit breaker. A moving mechanism is installed on the middle compartment bottom plate 4, which drives the circuit breaker 2 to move forward and backward in the middle compartment 3; before the circuit breaker 3 is shaken in, the grounding knife is switched to the separated state.

[0052] In one embodiment, the moving mechanism includes a power mechanism 7 , a side rail 5 and a support rail 6 .

[0053] The side rail 5 is fixedly connected between the side of the circuit breaker 2 and the cabinet 1, so that the circuit breaker 2 moves in a straight line in the middle compartment 3; the side rail 5 is a ball guide rail, which provides precise linear guidance for the circuit breaker 2 when the circuit breaker 2 moves, so that the circuit breaker 2 can smoothly enter the working position.

[0054] In specific implementation, it can be selected whether to install the side rail 5 according to the distance between the circuit breaker 2 and the cabinet 1. When the side rail 5 is not used, the power mechanism 7 adopts a linear motor, which can easily provide accurate linear guidance for the circuit breaker 2, so that the circuit breaker 2 can smoothly enter the working position.

[0055] The support rail 6 is fixedly connected between the middle compartment bottom plate 4 and the circuit breaker 2 and is located on both sides of the power mechanism 7; the support rail 6 is a roller guide rail, which plays a major supporting role for the circuit breaker, reduces the pressure of the circuit breaker on the power mechanism 7, and improves the support for the circuit breaker 2. It avoids the deformation of the rail after long-term use, which causes the circuit breaker 2 to be offset or the moving position is inaccurate when the power mechanism 7 is driven, resulting in the switch cabinet being unable to enter the normal closing and power transmission operation.

[0056] The support track 6 includes a moving member 61 and a track frame 62;

[0057] The track frame 62 includes a first track 622 and a second track 624;

[0058] The moving member 61 includes a first connecting frame 612 and a second connecting frame 613. The first connecting frame 612 and the second connecting frame 613 are both rotatably connected with rolling members, and the rolling members include rollers 63. In one embodiment, the rollers 63 include a solid short and thick main shaft, bearings are sleeved at both ends of the main shaft, and a ring is sleeved on the outer ring of the bearing. This structure enables the rolling member to have a larger bearing capacity and avoid deformation after long-term use.

[0059] The two rolling members are rollingly connected to the first track 622 and the second track 624. A connecting platform 611 is arranged on the first connecting frame 612, and the connecting platform 611 is fixed on the circuit breaker 2.

[0060] The first track 622 and the second track 624 are both provided with a support structure, and the first track 622 and the second track 624 are located at different levels through the support structure to form a first moving track and a second moving track, and the two rolling elements move on the first moving track and the second moving track respectively. In this embodiment, the first moving track and the second moving track have the same moving direction.

[0061] The track frame 62 also includes a base 625, which is fixed on the middle warehouse bottom plate 4. The support structure is provided at both ends of the top of the base 625;

[0062] The first track 622 is formed on the top of the support structure, and the second track 624 is formed on the upper surface of the base 625 between the two support structures.

[0063] The second track 624 is provided with a reinforcing plate 626 fixedly connected to the base 625, and the bottom of the reinforcing plate 626 is a convex portion 627 protruding downward. The convex portion 626 is semi-elliptical, semi-circular or rectangular.

[0064] Specifically, the upper rolling member presses on the support structure when rotating on the first track 622, and the weight of the circuit breaker 2 brought by the rolling member is borne by the support structure. The lower rolling member presses on the reinforcing plate 626 when rotating on the second track 624, and the weight of the circuit breaker 2 brought by the rolling member is borne by the reinforcing plate 626.

[0065] The weight of the circuit breaker 2 is distributed by the rolling element on the second rail 624 and the two first rails 622, which reduces the weight pressure on a single rail and makes the support rail 6 more resistant.

[0066] The supporting structure is a plurality of vertical supporting beams 623, and the supporting beams 623 on the left and right sides enclose a first limiting cavity. A frame 621 is provided on the top side of the supporting beam 623, and the two frames 621 enclose a second limiting cavity.

[0067] When the two rolling elements move along the first moving track and the second moving track, they are limited in the first limiting cavity and the second limiting cavity;

[0068] In another embodiment, the power mechanism 7 is fixedly connected between the middle compartment bottom plate 4 and the circuit breaker 2 to drive the movement of the circuit breaker 2 .

[0069] In this embodiment, the power mechanism 7 includes a mounting table 77 and a linear motor 71 .

[0070] The assembly platform 77 is detachably connected to the middle warehouse bottom plate 4 ; the linear motor 71 is fixed on the assembly platform 77 by the clamping platform 73 .

[0071] Among them, strip holes 74 are opened on both sides of the assembly platform 77, the linear motor 71 has a movable end, and the movable end extends outward to form an extended connecting platform 72. The extended connecting platform 72 has bolt holes. The bolts pass through the bolt holes and are fixed to the circuit breaker 2 as a whole. The bolt holes and the strip holes 74 are located on the same axis.

[0072] The two sides of the assembly platform 77 are respectively provided with abutment platform 76 and overlap platform 75;

[0073] The abutment platform 76 is attached to the bottom surface of the middle warehouse bottom plate 44 and fixedly connected by bolts. The lap platform 75 is buckled on the top surface of the middle warehouse bottom plate 44 and fixedly connected by bolts.

[0074] During use, if the linear motor 71 fails, a tool can be used to extend the strip hole 74 deep into the bolt hole of the extended connecting platform 72, and the bolt connected to the circuit breaker 2 can be unscrewed to separate the linear motor 71 from the circuit breaker 2. Remove the bolts connecting the lap platform 75 and the middle warehouse bottom plate 44 in the bottom warehouse, and then remove the bolts on one side of the abutment platform 76. At this time, one side of the abutment platform 76 of the middle warehouse bottom plate 44 will fall freely, and the power mechanism 7 can be taken out at an angle. It can also be installed directly after maintenance or replacement. The quickness of disassembly and assembly of the power mechanism 7 is simplified, and it can be completed without disassembling the circuit breaker 2, which is efficient and fast.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
