Description

Technical Field

[0001] This utility model relates to the field of power output and distribution technology, and more specifically, to a tooling for treating moisture absorption of common busbar insulation. Background Technology

[0002] A common-enclosure busbar refers to a conductor system within a substation consisting of several single-phase or multi-phase parallel conductors enclosed in the same metal casing, forming a closed busbar system. The conductors of the common-enclosure busbar are made of copper-aluminum or channel aluminum-channel copper, while the casing is made of aluminum plate. For high-current common-enclosure busbars, ventilation holes can be installed at appropriate locations. Flexible connections are used at the junctions of transformers, generators, and distribution cabinets with the common-enclosure busbar. Rubber pads are added between the casings to reduce vibration. In rainy weather, the common-enclosure busbar insulation of generator sets and transformers is prone to moisture absorption, which can affect the stable operation of the unit. Therefore, a tooling solution for treating moisture absorption in common-enclosure busbar insulation has been designed. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a tooling for treating moisture-induced insulation of common busbars, which has the advantages of heating and moisture prevention.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A fixture for treating moisture absorption of common busbar insulation, comprising a busbar shell, a heating tube fixedly connected to the bottom end of the busbar shell, a temperature sensor fixedly connected to the lower surface of the busbar shell near the end of the heating tube, a heating cavity fixedly connected to the bottom end of the heating tube, a plurality of heating elements fixedly connected around the inner wall of the heating cavity, an output pipe fixedly connected to the bottom end of the heating cavity, a blower fixedly connected to the bottom end of the output pipe, and a turbulence mechanism provided at the top end of the busbar shell, the turbulence mechanism being used to control airflow organization to enhance turbulent heat transfer.

[0005] Preferably, a flange is fixedly connected at the connection between the heating tube and the busbar housing, and a wire is fixedly connected to the inner wall of the busbar housing.

[0006] Preferably, the inner wall of the heating tube is connected to the inner wall of the busbar housing, the inner wall of the heating cavity is connected to the inner wall of the heating tube, and the bottom end of the heating cavity is connected to the inner wall of the output tube.

[0007] Preferably, the top of the busbar housing is provided with a flow guide window, and the turbulence mechanism includes a plurality of flow guide plates rotatably connected to the inner wall of the flow guide window, and the outer wall of the flow guide plates is symmetrically fixedly connected with a rotating shaft.

[0008] Preferably, one side of the rotating shaft is rotatably connected to the inner wall of the guide window, and the other side of the rotating shaft is fixedly connected to a gear.

[0009] Preferably, a guide rail frame is fixedly connected to the outer wall of the flow guide window, and a sliding toothed plate is slidably connected to the inner wall of the guide rail frame, with the bottom end of the sliding toothed plate meshing with the outer wall of the gear.

[0010] Preferably, a manual slider is fixedly connected to the top of the sliding toothed plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides heating equipment such as a heating chamber and a blower at the bottom of the busbar casing. When the insulation of the common busbar is damp, the operator can start the blower. When the blower starts, it delivers airflow to the inner wall of the output pipe. The airflow is heated by the heating chamber, and the heating plates on the inner wall of the heating chamber heat the delivered airflow. Finally, the airflow is delivered to the inner wall of the busbar casing through the heating pipe for heating and drying. The insulation is then dried by the airflow, which improves the insulation of the common busbar and ensures stable operation of the equipment.

[0013] 2. This utility model features a turbulence mechanism at the top of the busbar casing. Before the inner wall of the busbar casing is heated and dried by a blower, the operator can manually push open a manual slider. The manual slider drives a sliding toothed plate to slide on the inner wall of the guide rail frame. Then, the sliding toothed plate rotates through a meshing transmission gear. The gear drives the guide plate to rotate at an angle through a rotating shaft. During heating and drying, the airflow will generate shear layer instability at the edge of the guide plate, inducing turbulent vortices, thereby enhancing turbulent heat transfer, reducing the aging of the busbar conductor and insulation components, and delaying insulation aging.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6 As shown, this utility model provides a tooling for treating moisture absorption of common busbar insulation, including a busbar housing 1, a heating tube 2 fixedly connected to the bottom end of the busbar housing 1, a temperature sensor 202 fixedly connected to the lower surface of the busbar housing 1 and the end located near the heating tube 2, a heating chamber 3 fixedly connected to the bottom end of the heating tube 2, a plurality of heating plates 301 fixedly connected around the inner wall of the heating chamber 3, an output pipe 302 fixedly connected to the bottom end of the heating chamber 3, a blower 303 fixedly connected to the bottom end of the output pipe 302, and a turbulence mechanism 5 provided at the top end of the busbar housing 1. The turbulence mechanism 5 is used to control the airflow organization to enhance turbulent heat transfer.

[0023] A flange 201 is fixedly connected to the connection between the heating pipe 2 and the busbar housing 1. A wire 101 is fixedly connected to the inner wall of the busbar housing 1. A flange connection is also provided at the connection between the heating pipe 2 and the heating chamber 3 to ensure airtightness. A bracket for fixing to the ground is provided at the bottom of the blower 303. When the blower 303 is running, it delivers airflow to the output pipe 302. When the airflow reaches the interior of the heating chamber 3, the heating element 301 dries and heats the airflow. Then, the dried hot airflow is delivered to the inner wall of the busbar housing 1 through the heating pipe 2. Finally, the dried hot airflow is used to dry and heat the inner wall and insulation of the busbar housing 1.

[0024] It should be noted that busbar casing 1 is the common busbar for the 60MW generator set transformer, and heating pipe 2 is fixed to the bottom of busbar casing 1 via flange 201.

[0025] The inner wall of the heating tube 2 is connected to the inner wall of the busbar housing 1, the inner wall of the heating chamber 3 is connected to the inner wall of the heating tube 2, and the bottom end of the heating chamber 3 is connected to the inner wall of the output tube 302.

[0026] It should be noted that a flange connection is provided between the heating tube 2, the heating chamber 3 and the output tube 302 to ensure airtightness. A valve is provided at the middle of the heating tube 2, which can be opened according to the operation of the busbar casing 1.

[0027] The busbar housing 1 has a flow guide window 4 at its top end, and the turbulence mechanism 5 includes several flow guide plates 501 rotatably connected to the inner wall of the flow guide window 4. Rotating shafts 502 are symmetrically fixed to the outer wall of the flow guide plates 501.

[0028] One side of the rotating shaft 502 is rotatably connected to the inner wall of the guide window 4, and the other side of the rotating shaft 502 is fixedly connected to the gear 503.

[0029] It should be noted that rubber pads are provided at both ends of the guide plate 501. Multiple guide plates 501 can be flipped by rotating the rotating shaft 502. When multiple guide plates 501 are flipped to the horizontal position and closed, the two ends of multiple guide plates 501 will close together. The rubber pads can seal after multiple guide plates 501 are closed. At the same time, when the flip angle of the guide plate 501 is greater than 25 degrees, the airflow generates shear layer instability at the edge of the guide plate 501, inducing turbulent vortices and enhancing turbulent heat transfer.

[0030] The guide rail frame 401 is fixedly connected to the outer wall of the flow guide window 4, and a sliding toothed plate 504 is slidably connected to the inner wall of the guide rail frame 401. The bottom end of the sliding toothed plate 504 meshes with the outer wall of the gear 503. A manual slider 505 is fixedly connected to the top end of the sliding toothed plate 504.

[0031] It should be noted that the operator can rotate the guide plate 501 by sliding the manual slider 505. The manual slider 505 drives the sliding toothed plate 504 to slide on the inner wall of the guide rail frame 401. When sliding, the bottom end of the sliding toothed plate 504 will rotate through the meshing transmission gear 503. The gear 503 will drive the guide plate 501 to flip through the rotating shaft 502.

[0032] Working principle and usage process of this utility model:

[0033] The specific operation is as follows: when drying is required, the operator needs to start the blower 303. The blower 303 will draw in cold air and deliver airflow into the output pipe 302 through the output end. When the airflow reaches the inner wall of the heating chamber 3 through the output pipe 302, the airflow will be heated and dried by multiple heating plates 301 on the inner wall of the heating chamber 3, so that the airflow forms a dry hot airflow after passing through the heating chamber 3. The hot airflow is finally delivered to the inner wall of the busbar shell 1 through the heating pipe 2. The hot airflow will heat and dry the insulation and wires 101 on the inner wall of the heating pipe 2. During the drying process, the temperature sensor 202 will detect the temperature of the inner wall of the busbar shell 1.

[0034] The operator can enhance the control of airflow organization and turbulent heat transfer by sliding the manual slider 505. The manual slider 505 drives the sliding toothed plate 504 to slide on the inner wall of the guide rail frame 401. When sliding, the bottom end of the sliding toothed plate 504 will rotate through the meshing transmission gear 503. The gear 503 will drive the guide plate 501 to flip through the rotating shaft 502. The guide plate 501 will flip to a certain angle on the inner wall of the guide window 4. At this time, the airflow inside the busbar shell 1 will generate shear layer instability at the edge of the guide plate, inducing turbulent vortices, thereby enhancing turbulent heat transfer, which can reduce the aging of busbar conductors and insulation components and delay insulation aging.
