Description

Technical Field

[0001] This utility model relates to the field of disconnect switches, specifically an insulating support structure for a disconnect switch. Background Technology

[0002] Disconnecting switches are an important type of switching equipment in power systems. They are used to isolate power sources and create a clear disconnection point to ensure the safety of maintenance personnel. They can also be used for switching operations and connecting or disconnecting low-current circuits. The insulating supports of disconnecting switches mainly serve to provide support and insulation.

[0003] Existing insulating support structures for disconnecting switches, such as the insulating support for a disconnecting switch proposed in patent application number "CN202420845931.0", include multiple insulating shells and an isolating blade disposed on the insulating shells. A connecting portion is provided between adjacent insulating shells, and an electrical connection end is provided on the side of the two outermost insulating shells away from the connecting portion. A second longitudinal insulating flange is provided on the outer side of the electrical connection end. This utility model uses the second longitudinal insulating flange to increase the creepage distance and avoid the creepage distance being too small due to dust, which would result in a large leakage current.

[0004] However, existing technologies have shortcomings. Disconnect switches can be installed outdoors or inside indoor power distribution equipment. When installed indoors, space is limited. Damage to the insulating support is difficult to repair due to space constraints, making the work of maintenance personnel more difficult and potentially causing safety problems. Therefore, an insulating support structure for disconnect switches is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an insulating support structure for a disconnecting switch to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An insulating support structure for a disconnecting switch includes a support body, a fixing seat fixedly connected to the lower end of the support body by bolts, a base fixedly connected to the lower end of the fixing seat, a mounting seat slidably connected to the outside of the base, the mounting seat being fixedly installed on the disconnecting switch, a connecting rod assembly rotatably installed at both ends of the base, a retaining frame fixedly connected to both ends of the mounting seat, both ends of the connecting rod assembly engaging with the retaining frame, and a sealing ring engaging between the lower end of the support body and the fixing seat.

[0008] Preferably, the linkage assembly includes a linkage that passes through and is rotatably connected to both ends of the base. Both ends of the linkage are fixedly connected to a locking plate, and both sets of locking plates are engaged with a locking frame. A protrusion for applying force is fixedly connected to one side of the locking plate.

[0009] Preferably, the mounting base has sliding grooves at both ends, the base is located between the two sets of sliding grooves, and sliders are threaded to both sides of the base. The sliders slide in the sliding grooves and are used to prevent the base from detaching from the mounting base.

[0010] Preferably, the fixing seat is inserted into the lower end of the support body, and an installation ring is installed on the inner wall of the lower end of the support body. A sealing ring is fixed to the lower end of the installation ring, one side of the sealing ring is in contact with the inner wall of the support body, and the lower end of the sealing gasket is pressed and in contact with the upper end of the fixing seat.

[0011] Preferably, a pressure ring is fixedly connected to the upper end of the fixed seat. The cross-sectional shape of the pressure ring is set as a right trapezoid, and the inclined surface of the pressure ring is squeezed and fitted with the inner ring of the sealing ring.

[0012] Preferably, a fixing plate is fixedly connected to the lower end of the support body, and an insertion port is opened in the middle of the fixing plate. A connecting plate is fixedly connected to the side wall of the fixing seat, and the connecting plate is inserted into the insertion port. The connecting plate and the fixing plate are fixedly connected by bolts.

[0013] The beneficial effects of this utility model are:

[0014] This utility model uses a fixed base, a base, and a mounting base at the bottom of the support body to install and fix it on the disconnect switch. When space is limited and maintenance is inconvenient, the connecting rod assembly is rotated to disengage the connecting rod assembly from the locking frame. Then, the connecting rod assembly is pulled out to remove the base, allowing the support body to move out of the power distribution equipment, increasing maintenance space and reducing the difficulty of maintenance work.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] An insulating support structure for a disconnecting switch, such as Figures 1-4 As shown, the support includes a support body 3. The lower end of the support body 3 is fixedly connected to a fixing seat 4 by bolts. The lower end of the fixing seat 4 is fixedly connected to a base 2. The base 2 is slidably connected to an mounting seat 1. The mounting seat 1 is fixedly installed on the disconnecting switch. Both ends of the base 2 are rotatably mounted with connecting rod assemblies. Both ends of the mounting seat 1 are fixedly connected with a retaining frame 13. Both ends of the connecting rod assembly are engaged with the retaining frame 13. A sealing ring 10 is engaged between the lower end of the support body 3 and the fixing seat 4.

[0024] The insulating support includes a support body 3, a fixing seat 4, a base 2, and a mounting seat 1. The insulating support is installed and fixed on the disconnecting switch through the fixing seat 4, base 2, and mounting seat 1 at the bottom of the support body 3. During installation, both ends of the connecting rod assembly are engaged in the frame 13, so that the base 2 is positioned on the mounting seat 1. When the insulating support is damaged and needs to be repaired, but the space is limited and repair is inconvenient, the connecting rod assembly is rotated to disengage from the frame 13. Then, the connecting rod assembly is pulled to remove the base 2, allowing the support body 3 to be moved out of the power distribution equipment, increasing the maintenance space and reducing the difficulty of maintenance.

[0025] like Figure 1 As shown, the linkage assembly includes a linkage that passes through and is rotatably connected to both ends of the base 2. Both ends of the linkage are fixedly connected to a locking plate 14. Both sets of locking plates 14 are engaged with the locking frame 13. A protrusion 15 for applying force is fixedly connected to one side of the locking plate 14.

[0026] The connecting rod can only rotate and cannot slide relative to the base 2. The number of locking frames 13 is set to twice the number of connecting rods, and they are located at both ends of the connecting rods respectively, so that each set of locking plates 14 is engaged with one of the sets of locking frames 13. After engagement, the connecting rod restricts the base 2 to the mounting seat 1. The mounting seat 1 is mounted on the disconnecting switch via the mounting plate 16. In order to facilitate the rotation of the connecting rod, a protrusion 15 is added to the side of the locking plate 14 to facilitate applying force to drive the connecting rod to rotate.

[0027] like Figure 1 As shown, the mounting base 1 has sliding grooves 11 at both ends, the base 2 is located between the two sets of sliding grooves 11, and the base 2 is threadedly connected to both sides of the base 2. The sliding sliders 12 slide in the sliding grooves 11 and are used to restrict the base 2 from detaching from the mounting base 1.

[0028] The slider 12 is threaded and detachable, which facilitates the separation of the base 2 and the mounting base 1, increases the sliding restriction between the base 2 and the mounting base 1, and prevents the base 2 from detaching from the upper end of the mounting base 1.

[0029] like Figures 1-4 As shown, the fixing seat 4 is inserted into the lower end of the support body 3. An installation ring 9 is installed on the inner wall of the lower end of the support body 3. A sealing ring 10 is fixed to the lower end of the installation ring 9. One side of the sealing ring 10 is in contact with the inner wall of the support body 3, and the lower end of the sealing gasket is pressed and in contact with the upper end of the fixing seat 4.

[0030] The insulating support adopts a split structure, which facilitates the replacement of damaged parts and reduces maintenance costs. The sealing ring 10 is squeezed to seal the connection between the support body 3 and the fixing seat 4, preventing moisture from entering the connection.

[0031] like Figure 3 As shown, a pressure ring 8 is fixedly connected to the upper end of the fixed base 4. The cross-sectional shape of the pressure ring 8 is set as a right trapezoid, and the inclined surface of the pressure ring 8 is squeezed and fitted with the inner ring of the sealing ring 10.

[0032] When the support body 3 is aligned and inserted with the fixing seat 4, the pressure ring 8 enters the support body 3 first. Since the outer ring at the upper end of the pressure ring 8 is small and the outer ring at the lower end is large, the pressure ring 8 can easily enter the sealing ring 10 and squeeze the sealing ring 10, thereby increasing the tightness and sealing of the sealing ring 10 to the connection part.

[0033] like Figures 1-4 As shown, a fixing plate 7 is fixedly connected to the lower end of the support body 3. An insertion port 6 is opened in the middle of the fixing plate 7. A connecting plate 5 is fixedly connected to the side wall of the fixing seat 4. The connecting plate 5 is inserted into the insertion port 6, and the connecting plate 5 and the fixing plate 7 are fixedly connected by bolts.

[0034] The support body 3 and the fixed base 4 are fixedly connected by the fixing plate 7, the connecting plate 5 and the bolts, ensuring stable installation.

[0035] The working principle of the insulating support structure of the disconnecting switch provided by this utility model is as follows:

[0036] The insulating support is installed and fixed on the disconnecting switch via the fixing seat 4, base 2 and mounting seat 1 at the bottom of the support body 3. During installation, both ends of the connecting rod assembly are engaged in the frame 13, so that the base 2 is positioned on the mounting seat 1. When the insulating support is damaged and needs to be repaired, but the space is limited and repair is inconvenient, the connecting rod assembly is rotated to disengage from the frame 13. Then the connecting rod assembly is pulled to remove the base 2, so that the support body 3 can be moved out of the power distribution equipment, increasing the maintenance space and reducing the difficulty of maintenance work.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
