Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically to a winding installation structure for a dry-type transformer. Background Technology

[0002] A dry-type transformer is a power device that uses air or other solid insulating materials as the cooling and insulating medium. It is widely used in power systems, industry, construction, new energy and transportation. The winding of a dry-type transformer is the core component that enables power transmission and voltage transformation.

[0003] In existing dry-type transformer installations, the windings are mounted on a base and connected to the base using bolts. To improve safety, insulating pads are often placed under the windings during installation. However, this method involves placing the insulating pads on the base and then placing the windings on top. This method suffers from poor stability when the pads are on the base, leading to the pads easily falling off and requiring repeated, cumbersome, and inconvenient positioning of the insulating pads. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a winding installation structure for a dry-type transformer to solve the technical problem that the current pads are prone to falling off and it is not convenient to position and install the insulating pads.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a winding installation structure for a dry transformer, including: a base, the number of the bases being two, the two bases being symmetrically arranged, and a plurality of evenly distributed connecting plates being fixedly installed between the two bases, with connecting holes provided on both sides of the top of the connecting plates; It also includes: an insulating pad assembly, wherein there are multiple insulating pad assemblies, which are evenly distributed at both ends of multiple connecting plates. Each insulating pad assembly includes a fixed shell, an insulating component is inserted into the inner cavity of the fixed shell, a limit block is fixedly connected to one side of the bottom of the fixed shell, and limit slots are opened on both sides of the top of the connecting plates, and the limit block is inserted into the limit slot.

[0006] Specifically, the limiting block is inserted into the limiting slot, so that the insulating pad assembly can be stably placed on the top of the connecting plate. The insulating pad assembly is located on the top of the base to ensure the stability of the support. Then, the connecting feet at the bottom of the winding are aligned with the connecting holes on the connecting plate. Then, the winding is installed by connecting the connecting holes and the connecting feet at the bottom of the winding with bolts. The winding can be placed on the insulating pad assembly, thereby using the insulating pad assembly to achieve stable support for the winding.

[0007] Preferably, the insulating pad assembly includes a fixed shell, the bottom of the fixed shell and the limiting insert are fixedly connected, a screw is rotatably installed on the lower side of the inner cavity of the fixed shell, a matching threaded slider is fitted on the outer wall of the screw, an inclined surface is opened on one side of the top of the threaded slider, and a wedge plate is fixedly connected to the bottom of the insulating assembly, the wedge plate is attached to the inclined surface at the top of the threaded slider.

[0008] Specifically, when the winding is placed on the insulating pad assembly, the rotating screw can drive the threaded slider to move, thereby creating a thrust on the wedge plate, which in turn moves the wedge plate upward, pushing the insulating assembly upward, so that it can fit against the winding, improving the fit and thus helping to improve the stability of the insulating assembly's support for the winding.

[0009] Preferably, one end of the screw movably passes through the fixed shell and is fixedly connected to a rotating block. The rotating block facilitates the rotation of the screw, thus improving operational convenience.

[0010] Preferably, the insulating assembly includes a carrier plate, with insulating positioning rods fixed on both sides of the top of the carrier plate, and multiple stacked insulating pads provided on the top of the carrier plate. The insulating pads are movably fitted onto the insulating positioning rods, and the bottom of the carrier plate is fixedly connected to a wedge plate.

[0011] Specifically, multiple insulating pads are stacked to form an insulating block. When the insulating pads are damaged after long-term use, the carrier plate and the insulating pads can be lowered by a certain distance, creating space under the winding. This allows the insulating pads to be removed one by one for easy replacement without disassembling the winding, thus improving operational convenience.

[0012] Preferably, limit strips are fixed on the lower sides of both sides of the inner cavity of the fixed shell. The limit strips provide support for the carrier plate, thereby achieving initial positioning of the carrier plate.

[0013] Preferably, notches are provided on both sides of the fixing shell. The notches allow the insulating pad to be removed by fingers through the notches, thereby further improving the ease of operation.

[0014] Preferably, mounting holes are provided on both sides of the bottom of the base, which facilitates the installation and fixing of the entire device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model has a positioning plug connected to one side of the bottom of the insulating pad assembly, and a positioning slot is provided on the connecting plate. When installing the insulating pad assembly, the positioning plug is inserted into the positioning slot for positioning and installation, which helps to improve the stability of the pad during installation and avoids the pad from falling off and causing operational trouble.

[0016] 2. This utility model uses a rotating screw to drive a threaded slider to move, and the inclined surface on the threaded slider can push the wedge plate to move upward, thereby moving the insulation component upward, thus adjusting the height of the insulation component, which helps to improve the fit between the insulation component and the winding, and thus helps to improve the stability of the support. The insulation assembly consists of multiple insulating sheets, a carrier plate, and an insulating positioning rod. When the insulating pads wear out after long-term use, the insulation assembly can be lowered by a certain distance, and then the insulating pads can be removed one by one. This eliminates the need to disassemble the winding to replace the pads, thus improving the convenience of replacement. Attached Figure Description

[0021] It should be understood that in actual use, the limiting plug 15 is inserted into the limiting slot 14, so that the insulating pad assembly can be stably placed on the top of the connecting plate 11 and the insulating pad assembly is located on the top of the base 1 to ensure the stability of the support. Then, the connecting feet at the bottom of the winding are aligned with the connecting holes 12 on the connecting plate 11, and the winding is installed by connecting the connecting holes 12 and the connecting feet at the bottom of the winding with bolts. The winding can be placed on the insulating pad assembly, thereby using the insulating pad assembly to achieve stable support for the winding.
