Description

Technical Field

[0001] The utility model belongs to the field of current transformer installation, and particularly relates to a current transformer installation structure. Background Art

[0002] The current transformer is an instrument that converts the large current on the primary side into a small current on the secondary side for measurement based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. Its primary winding has very few turns and is connected in series in the circuit of the current to be measured.

[0003] At present, the Chinese utility model with the announcement number: CN 211479808 U discloses a mounting structure of a current transformer, which belongs to the technical field of current transformer installation equipment. A mounting structure of a current transformer includes a fixed lower slot block, wherein a fixed slot is provided inside the fixed lower slot block, and a current transformer is inserted inside the fixed slot. The mounting structure of the current transformer is arranged such that when installing the current transformer, the upper and lower ends of the current transformer are firstly sleeved in the fixed upper slot block and the fixed lower slot block to complete preliminary fixation, and the reinforcing screw and the second reinforcing screw are connected inside the reinforcing opening and the second reinforcing opening, so that the reinforcing screw and the second reinforcing screw are pressed against the current transformer to strengthen the fixation thereof, and the fixed connection block strengthens the connection between the fixed upper slot block and the fixed lower slot block through the third fixing screw, thereby strengthening the fixation of the current transformer, thereby achieving the purpose of better fixation of the current transformer by the mounting structure.

[0004] The installation structure has a strong wrapping effect on the current transformer during use, which has a certain impact on the heat dissipation effect of the current transformer. It is not highly compatible with current transformers of different sizes. It is also not convenient to adjust the installation angle of the current transformer according to usage requirements, which has limitations in use. Utility Model Content

[0005] The purpose of the utility model is to provide an installation structure for a current transformer, which has the advantages of being easy to install current transformers of different sizes, increasing usage compatibility, and facilitating improving the flexibility of the current transformer in the installation scenario.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a mounting structure of a current transformer, comprising a base, a movable plate is provided on the top of the base, extension plates are provided at both ends of the bottom of the movable plate, a mounting block located at one end of the movable plate is fixedly installed on one end of the extension plate, a bolt 1 penetrating to the top of the movable plate is fixedly installed on the top of the extension plate, a rod body is fixedly installed on the bottom of the movable plate, the rod body penetrates into the interior of the base and is rotatably connected with the base, bolt 2 and bolt 3 are respectively provided on one side and surface of the base, knob 2 and knob 3 are respectively fixedly installed on one end of the bolt 2 and bolt 3, and an inner cavity for accommodating the rod body is opened inside the base.

[0007] Adopting the above technical scheme: when installing the current transformer, the distance between the two mounting blocks can be adjusted according to the mounting hole position of the current transformer. The operator preferentially turns the knob 1 so that the knob 1 moves on the surface of the bolt 1. After the knob 1 cancels the contact with the top of the shift plate, the position of the moving extension plate at the bottom of the shift plate can be moved, wherein the sliding connection of the slider and the slide groove cooperates with the extension plate to move and guide at the bottom of the shift plate, and the bolt 1 also moves inside the through groove. After the two mounting blocks are moved to the appropriate required position, the knob 1 is rotated in the opposite direction so that the knob 1 contacts the shift plate during the movement, thereby realizing the limit fixation of the position between the shift plate and the extension plate. Through this setting, it is convenient to install current transformers of different sizes, increase the compatibility of the use of the mounting structure, improve the scope of application of the current transformer, and the structure does not occupy too much space on both sides in actual use. When installing the current transformer, the mounting structure will preferentially be installed through the mounting hole 2 in conjunction with the external bolt and the required mounting position, and the embedded groove cooperates with the external bolt to accommodate and embed. When the installation angle of the current transformer needs to be adjusted, knob two and knob three can be turned first. At this time, the threaded connection will enable the rotation of bolt two and bolt three to achieve progressive movement inside the base. The movement of bolt two and bolt three will drive the contact block to make synchronous contact. After the two contact blocks are no longer in contact with the rod body, the rod body and the shift plate can be rotated on the top of the base. After the current transformer is adjusted to an appropriate angle, if one of knob two or knob three is blocked by the extension plate, knob three or knob two, which is easier to adjust at the moment, can be selected for rotation. After the contact block contacts the rod body again, the rod body can be limited, thereby achieving the angle limit of the extension plate and the current transformer. This setting facilitates improving the flexibility of the current transformer installation scenario.

[0008] The utility model is further configured that both ends of the interior of the mounting block are provided with mounting holes 1.

[0009] The above technical solution is adopted: the external bolts are matched with the current transformer through the installation hole to fasten the installation.

[0010] The utility model is further configured that both ends of the shift plate are provided with through grooves for fitting bolts to pass through.

[0011] By adopting the above technical solution, the matching bolt 1 is passed through the shifting plate through the through groove, and at the same time, the bolt 1 is moved inside the shifting plate.

[0012] The utility model is further configured that the surface of the bolt 1 is threadedly connected with a knob 1 located on the top of the shifting plate.

[0013] By adopting the above technical solution, the rotation of the knob 1 will drive the bolt 1 to rotate.

[0014] The utility model is further configured that sliding blocks are fixedly installed on both sides of the top of the extension plate, and sliding grooves for cooperating with the sliding blocks are opened on both sides of the bottom of the shift plate.

[0015] The above technical solution is adopted: the sliding connection between the slider and the slide groove is used to cooperate with the extension plate to guide the movement at the bottom of the moving plate.

[0016] The utility model is further configured such that one end of the second bolt and the third bolt both penetrate into the inner cavity and are fixedly provided with a contact block in contact with the rod body.

[0017] By adopting the above technical solution, the movement of the second bolt and the third bolt will drive the contact block to contact the rod body, and during the contact between the rod body and the contact block, friction limiting between the contact block and the rod body will be achieved.

[0018] The utility model is further configured such that the second bolt and the third bolt are threadedly connected to the base, and balls are rotatably connected to the top of the base and located on both sides of the rod body.

[0019] The above technical solution is adopted: the rotation of bolts 2 and 3 is realized through threaded connection to achieve progressive movement inside the base, and the ball bearing reduces the friction between the base and the shifting plate.

[0020] The utility model is further configured that embedding grooves are provided on both sides of both ends of the base, and a second mounting hole located at the bottom of the embedding groove is provided inside the base.

[0021] The above technical solution is adopted: the embedding groove is used to accommodate and embed the external bolts, and the second mounting hole is used to install and penetrate the external bolts.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. When installing a current transformer, the utility model can preferentially adjust the distance between the two mounting blocks according to the mounting hole position of the current transformer. The operator preferentially turns knob one to move knob one on the surface of bolt one, and after knob one cancels contact with the top of the shift plate, the position of the extension plate at the bottom of the shift plate can be moved. After the two mounting blocks are moved to the appropriate desired positions, turn knob one in the opposite direction to limit and fix the position between the shift plate and the extension plate. This setting can facilitate the installation of current transformers of different sizes, increase the compatibility of the installation structure, improve the scope of application of the current transformer, and the structure does not take up too much space on both sides in actual use;

[0024] 2. When the utility model is installing the current transformer and needs to adjust the installation angle of the current transformer, knob two and knob three can be rotated first. At this time, the threaded connection will enable the rotation of bolt two and bolt three to achieve progressive movement inside the base. After the two contact blocks are no longer in contact with the rod body, the rod body and the shift plate can be rotated on the top of the base. After the current transformer is adjusted to an appropriate angle, knob three or knob two, which is easier to adjust at the moment, can be selected for rotation. After the contact block contacts the rod body again, the rod body can be limited, thereby achieving the angle limitation of the extension plate and the current transformer. This setting facilitates improving the flexibility of the current transformer installation scenario. BRIEF DESCRIPTION OF THE DRAWINGS

After the knob 8 cancels the contact with the top of the shift plate 2, the position of the extension plate 3 at the bottom of the shift plate 2 can be moved. After the two mounting blocks 4 are moved to the appropriate required position, the knob 8 is turned in the opposite direction, so as to realize the limit fixation of the position between the shift plate 2 and the extension plate 3. Through this setting, it is convenient to install current transformers of different sizes, increase the compatibility of the installation structure, and improve the application range of the current transformer. In actual use, the structure does not occupy too much space on both sides.

[0034] refer to Figure 2 Both ends of the moving plate 2 are provided with through grooves 7 for the matching bolts 6 to pass through. When the matching bolts 6 pass through the through grooves 7 to pass through the moving plate 2, the bolts 6 can be moved inside the moving plate 2.

[0035] refer to Figure 1 The surface of the bolt 6 is threadedly connected with a knob 8 located at the top of the shift plate 2, and the rotation of the knob 8 will drive the bolt 6 to rotate.

[0037] Brief description of the use process: When installing the current transformer, the distance between the two mounting blocks 4 can be adjusted according to the mounting hole position of the current transformer. The operator first turns the knob 8 so that the knob 8 moves on the surface of the bolt 6.

When the current transformer is installed, when the installation angle of the current transformer needs to be adjusted, the knob 2 14 and the knob 3 16 can be rotated first. At this time, the threaded connection will enable the rotation of the bolt 2 13 and the bolt 3 15 to realize progressive movement inside the base 1. After the two contact blocks 19 are no longer in contact with the rod body 11, the rotation of the rod body 11 and the shift plate 2 at the top of the base 1 can be realized, and then after the current transformer is adjusted to an appropriate angle, the knob 3 16 or the knob 2 14 that is easier to adjust at the moment can be selected for rotation. After the contact block 19 contacts the rod body 11 again, the rod body 11 can be limited, thereby achieving the angle limitation of the extension plate 3 and the current transformer. This setting facilitates improving the flexibility of the current transformer installation scenario.

[0040] refer to Figure 4 One end of the second bolt 13 and the third bolt 15 penetrates into the inner cavity 12 and is fixedly installed with a contact block 19 that contacts the rod body 11. The movement of the second bolt 13 and the third bolt 15 will drive the contact block 19 to contact the rod body 11. During the contact between the rod body 11 and the contact block 19, friction limiting between the contact block 19 and the rod body 11 will be achieved.

[0041] refer to Figure 4 Bolt 2 13 and bolt 3 15 are threadedly connected to the base 1. Balls 20 are rotatably connected to the top of the base 1 and both sides of the rod body 11. The threaded connection enables the rotation of bolt 2 13 and bolt 3 15 to achieve progressive movement inside the base 1. The ball 20 reduces the friction between the base 1 and the shift plate 2.

The embedding groove 17 is used to accommodate and embed the external bolts, and the second mounting hole 18 is used to install and penetrate the external bolts.

[0043] Brief description of the use process: When installing the current transformer, the installation structure will be installed and used through the installation hole 2 18 in conjunction with the external bolts and the required installation position, and the embedded groove 17 will be used to accommodate the external bolts. When the installation angle of the current transformer needs to be adjusted, the knob 2 14 and the knob 3 16 can be rotated first. At this time, the threaded connection will enable the rotation of the bolt 2 13 and the bolt 3 15 to achieve progressive movement inside the base 1. The movement of the bolt 2 13 and the bolt 3 15 will drive the contact block 19 to make synchronous contact. After the two contact blocks 19 are no longer in contact with the rod body 11, the rod body 11 and the shift plate 2 can be rotated on the top of the base 1. Then, after the current transformer is adjusted to an appropriate angle, if one of the knobs 2 14 or the knobs 3 16 is blocked by the extension plate 3, the knob 3 16 or the knob 2 14, which is easier to adjust at the moment, can be selected for rotation. After the contact block 19 contacts the rod body 11 again, the rod body 11 can be limited, thereby achieving the angle limitation of the extension plate 3 and the current transformer. This setting facilitates improving the flexibility of the current transformer installation scenario.
