Description

Technical Field

[0001] The invention belongs to the field of insulating baffles, and in particular relates to an insulating baffle for a switch compartment in a switch cabinet. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The 10kV central switch cabinet of the substation consists of four parts: protection compartment, switch compartment, busbar compartment and cable compartment. When the switch compartment of the switch cabinet needs maintenance work, the trolley switch needs to be pulled to the maintenance position. At this time, the baffle isolating the live parts in the switch compartment is closed, but the static contact of the switch compartment is connected to the live busbar. When the maintenance personnel lean into the switch compartment for maintenance, there is a risk of electric shock if they accidentally touch the isolation baffle.

[0004] The existing method is to use an insulating rod to lift the rope loop above the square insulating baffle and extend it to the switch compartment, so that the insulating baffle stands obliquely against the switch compartment isolation baffle. After the maintenance is completed, the insulating baffle is picked out with the insulating rod. This method not only makes the insulating baffle unstable, but also makes it very inconvenient to place and take it out through the rope loop.

[0005] At the same time, due to the different uses of switch cabinets and different sizes of switch compartments, the sizes of the required insulating baffles are also different. Different switch cabinets need to be equipped with insulating baffles of different sizes, which increases the cost. Summary of the invention

[0006] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides an insulating baffle for a switch compartment in a switch cabinet. The height of the insulating baffle can be adjusted through the control of a controller, and the insulating baffle can be expanded to different areas through the extension and retraction of the telescopic structure, which can adapt to the requirements of different insulating baffle sizes.

[0010] Furthermore, the telescopic mechanism is a multi-section telescopic rod, and the telescopic rods are connected at an angle through an adjustment plate.

[0011] Furthermore, the multi-section telescopic rod is connected to the first section corresponding to the multi-section telescopic rod through a first insulating sheet group, and the multi-section telescopic rod is connected to the second section corresponding to the multi-section telescopic rod through a second insulating sheet group, and the first insulating sheet group and the second insulating sheet group are slidably connected between the upper and lower corresponding positions.

[0012] Furthermore, a driving module and a driving motor are provided on the multi-section telescopic rod, the driving module is used to control the driving motor, and the driving motor is used to control the extension and retraction of the multi-section telescopic rod.

[0013] Furthermore, a travel contact is provided at the top end of the multi-section telescopic rod, and the travel contact is connected to a controller.

[0026] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] It should be noted that the terms used herein are for describing specific embodiments only and are not intended to be limiting of exemplary embodiments according to the present invention.

[0028] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0029] Embodiment 1

[0030] The present embodiment discloses an insulating baffle for a switch compartment in a switch cabinet, comprising: an insulating baffle, a base, and a telescopic mechanism. The insulating baffle and the base are connected by a height adjustment mechanism. The telescopic mechanism is parallel to the diagonal of the insulating baffle and extends outward along the diagonal direction. An insulating sheet is arranged between the telescopic mechanism and the telescopic structure.

[0031] In this embodiment, the height adjustment mechanism includes a cross bar arranged in the middle position of the insulating baffle, and an automatic telescopic rod 2 is fixedly connected to the cross bar. The automatic telescopic rod includes a first automatic telescopic rod and a second automatic telescopic rod. The first automatic telescopic rod and the second automatic telescopic rod are fixedly connected to both ends of the cross bar respectively. The bottoms of the first automatic telescopic rod and the second automatic telescopic rod are fixedly connected to the base, and a travel limit mechanism is arranged on the base.

[0032] Specifically, the insulating baffle is vertical when in use, and a cross bar is fixedly provided in the middle position of the insulating baffle in parallel with the ground. The cross bar and the insulating baffle can be fixedly connected by welding or bonding. A first automatic telescopic rod and a second automatic telescopic rod are fixedly connected to both ends of the cross bar, respectively. The top end of the automatic telescopic rod and the cross bar can be fixedly connected by bonding or the like. Bases are respectively connected to the bottom ends of the first automatic telescopic rod and the second automatic telescopic rod, and a travel limit mechanism is provided on the base.

[0033] The travel limiting mechanism comprises a driving motor and a driving wheel, and a distance measuring sensor arranged on the same side of the first automatic telescopic rod and the second automatic telescopic rod, and the driving motor and the distance measuring sensor are respectively connected to the controller.

[0034] Specifically, a slot is formed by an upward depression on the bottom surface of the base, and the driving wheel is movably arranged in the slot. A turbine worm assembly for driving the driving wheel to rotate is arranged in the slot, and the axial direction of the worm is extended in the horizontal direction. The worm is drivenly connected to the worm, and the axial direction of the turbine is extended in the vertical direction and is perpendicular to the axial direction of the worm. A driven turntable meshing with the outer surface of the turbine is connected to the driving wheel, and the axial direction of the driven turntable extends in the horizontal direction. The driven turntable is connected to the driving wheel through a connecting assembly. The connecting rod assembly includes a base forming a placement cavity, and a driving motor is arranged in the base and connected to the driving wheel to drive the rotation of the driving wheel. The driving motor is connected to a controller, and the driving motor receives control instructions from the controller to realize the movement or stop of the driving wheel.

[0035] A distance measuring sensor is arranged on the same side of the first automatic telescopic rod and the second automatic telescopic rod, and is arranged in the direction toward the inner wall of the switch compartment. During the movement, the distance measuring sensor measures and sends the data to the controller. The controller determines whether it has moved to the appropriate position in the switch compartment according to the distance data measured by the distance measuring sensor. After moving to the appropriate position, the controller controls the phase of the drive motor to send an instruction to control the drive motor to stop working.

[0036] The control modules of the first automatic telescopic rod and the second automatic telescopic rod are connected to the controller, and the controller controls the telescopic movement of the first automatic telescopic rod and the second automatic telescopic rod.

[0037] It is understandable that the controller can determine whether the distance data measured by the distance measuring sensor exceeds a threshold value, and control the drive motor to stop controlling if the distance data exceeds the threshold value. The threshold value can be set according to actual conditions.

[0038] The telescopic mechanism is a multi-section telescopic rod 4, and the multi-section telescopic rod 4 is connected to the multi-section telescopic rod 4 at an angle through an adjustment plate.

[0039] Specifically, the first telescopic rod, the second telescopic rod, the third telescopic rod and the fourth telescopic rod are respectively fixedly connected to the adjustment plate by bonding, and the first telescopic rod, the second telescopic rod, the third telescopic rod and the fourth telescopic rod are arranged in a manner approximately parallel to the diagonal of the insulating baffle, and the first telescopic rod, the second telescopic rod, the third telescopic rod and the fourth telescopic rod extend outward along the diagonal direction. The adjustment plate is also arranged at the center of the insulating baffle, and the adjustment plate can be arranged between the cross bar and the insulating baffle, and the adjustment plate and the insulating baffle and the cross bar are fixedly connected by welding or bonding.

[0040] The multi-section telescopic rod 4 is connected to the first section corresponding to the multi-section telescopic rod 4 through a first insulating sheet group, and the multi-section telescopic rod 4 is connected to the second section corresponding to the multi-section telescopic rod 4 through a second insulating sheet group. The first insulating sheet group and the second insulating sheet group are slidably connected between the corresponding upper and lower positions.

[0041] Specifically, the multi-section telescopic rod 4 includes a sleeve, a rotating shaft and a threaded tube respectively accommodated in the sleeve, and a driving motor arranged at one end of the sleeve and used to drive the rotating shaft to rotate. When the driving motor drives the rotating shaft to rotate, the rotating shaft pushes the threaded tube to move in a direction away from the motor, or the rotating shaft drives the threaded tube to retract toward the motor. A driving module is also provided on the multi-section telescopic rod 4. The driving module is used to control the action of the driving motor. The driving module is connected to the controller, and the controller sends a control command to the driving module.

[0042] The first section of the first telescopic rod is connected to the first section of the second telescopic rod and / or the first section of the third telescopic rod through a first insulating sheet group, the first insulating sheet group includes n insulating sheets 3, n=1, 2, 3, ..., and the insulating sheets 3 are connected to each other through sliding grooves.

[0043] Specifically, a slide groove is arranged in the horizontal direction on the outer surface of the first insulating sheet, and a convex strip is arranged on the inner surface of the adjacent second insulating sheet opposite to the first insulating sheet. The convex strip is located in the slide groove and can move horizontally along the slide groove. Similarly, a slide groove is arranged on the outer surface of the second insulating sheet, and a protrusion is arranged on the inner surface of the third insulating sheet, and the corresponding arrangements are performed in sequence.

[0044] The insulating sheet 3 is fixedly connected to the multi-section telescopic rod 4, each section of the multi-section telescopic rod 4 is connected to the insulating sheet 3, and the insulating sheet 3 can overlap up and down. When each section of the multi-section telescopic rod 4 is extended, the insulating sheet 3 of the overlapping part can move relatively, ensuring that the insulating sheet 3 is still shielded between the multi-section telescopic rods 4 after extension.

[0045] It can be understood that the shape of each layer of the insulating sheets 3 can be adaptively selected according to the number of insulating sheets 3 in each layer used and the number of sections of the multi-section telescopic rod 4 .

[0046] A travel contact 1 is provided at the top end of the multi-section telescopic rod 4 , and the travel contact 1 is connected to a controller.

[0047] Specifically, a travel contact 1 is provided at the top of the multi-section telescopic rod 4, and the travel contact 1 is connected to the controller. When the travel contact 1 senses the inner wall of the door opening compartment, it can be sent to the controller, and the telescopic length of the multi-section telescopic rod 4 can be controlled by the controller.

[0048] In addition, the insulating sheet 3 is made of epoxy resin, and the base is made of channel steel or angle steel.
