Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical field, in particular to a current transformer track mounting structure and switch cabinet. BACKGROUND

[0002] At present, the installation mode of the switch cabinet mutual inductor is to install the mutual inductor on the mounting plate of the rear door. Because the mutual inductor is relatively heavy, when power failure maintenance or mutual inductor replacement is needed, the rear lower door is opened, the human being drills into the cable chamber to loosen the mutual inductor mounting plate screw, and then the mutual inductor is removed to complete the replacement process, which brings great trouble to the on-site construction personnel. At the same time, the bottom space is limited when installing and constructing the cable, and other obstacles will affect the construction progress of the cable, which is not conducive to installation.

[0003] For this, the utility model patent No. 2024204647645 discloses a current transformer with quick disassembly and assembly structure, which installs the current transformer through the track, so as to facilitate the quick installation and disassembly of the current transformer.

[0004] But its fixed structure is fixed by aligning the limiting hole and the sliding hole and inserting or pulling out the sliding rod. But when installing, the limiting hole and the sliding hole need to be aligned for a long time adjustment, and when disassembling, the sliding rod needs to be pulled out to overcome the spring resistance, and when it is fixed in the deep position inside the switch cabinet structure, it will be difficult for the staff to exert force.

[0005] Here, the current transformer is heavy, so when pulling out along the slide rail after disassembly, the main force is the weight of the mutual inductor, and when the mutual inductor is separated from the slide rail, the staff will suddenly need to bear the whole weight of the current transformer. At this time, it is easy to cause the staff to not exert force in time due to the sudden increase in weight, resulting in the current transformer falling to the ground and causing damage or injury to the staff, so improvement is needed.

[0020] Figure 2 It is the cross section structure schematic view of the connecting rod of the first limiting connecting plate in the embodiment 2.

[0021] Figure 3 It is the structure schematic view of the first guide slide plate. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will be further explained in detail by combining with the drawings and examples.

[0023] Embodiment 1

[0024] As Figure 1 shown in the utility model discloses a current transformer track installation structure, including first adapter plate 1, current transformer 2, second adapter plate 3, first side plate 4, first guide slide plate 5, second side plate 6, second guide slide plate 7, first limiting connecting plate 8, connecting rod 81, limiting plate 82, second limiting connecting plate 9 and limiting waist hole 91.

[0025] Among them, the first adapter plate 1 four corners form bolt hole and are fixed in switch cabinet by bolt. The second adapter plate 3 four corners form bolt hole, and are fixedly connected by bolt on the top of current transformer 2.

[0026] The first adapter plate 1 both sides are fixed with first side plate 4, and the first side plate 4 outer side is fixed with horizontally arranged first guide slide plate 5, and the corresponding second adapter plate 3 both sides are fixed with second side plate 6, and the second side plate 6 inner side is fixed with second guide slide plate 7 matched with first guide slide plate 5.

[0027] In this way, the second guide slide plate 7 of second adapter plate 3 is above first guide slide plate 5, so that current transformer 2 is directly pushed into switch cabinet.

[0028] In order to facilitate quick fixing, the second adapter plate 3 front end is fixed with second limiting connecting plate 9, and the second limiting connecting plate 9 both sides form limiting waist hole 91;The first adapter plate 1 front end is fixed with first limiting connecting plate 8, and the first limiting connecting plate 8 is rotatably connected with connecting rod 81 through bearing, and the connecting rod 81 is connected with limiting plate 82 matched with limiting waist hole 91.

[0029] In this way, the limiting plate 82 is rotated to align with the limiting waist hole 91, the current transformer 2 is pushed to the bottom, so that the limiting plate 82 passes through the limiting waist hole 91, and then the limiting plate 82 is rotated to be clamped in the limiting waist hole 91, so that the fixing of the current transformer is realized.

[0030] A first grounding wire hole 87 is formed in the middle of the first limiting connecting plate 8 , and a second grounding wire hole 92 corresponding to the first grounding wire hole 87 is formed on the second limiting connecting plate 9 , thereby facilitating electrical connection of the current transformer to the ground wire.

[0031] Example 2

[0032] On the basis of embodiment 1, in order to prevent the limiting plate 82 from rotating arbitrarily and facilitate its rapid alignment with the limiting waist hole 91, as shown in FIG. Figure 2 As shown, four spherical grooves 83 are evenly formed along the circumferential direction in the middle of the connecting rod 81, and balls 84 are installed in the spherical grooves 83. A cylindrical groove 85 that cooperates with the spherical groove 83 is formed on the first limiting connecting plate 8, and a spring 86 is installed in the cylindrical groove 85.

[0033] When the limit plate 82 is twisted in this way, the spherical groove 83 presses the ball 84 into the cylindrical groove 85 until it is rotated 90 degrees and then the ball 84 rebounds back into the next spherical groove 83 under the pressure of the spring. In this way, the spherical groove 83 prevents the limit plate 82 from rotating freely. When the limit plate 82 is rotated 90 degrees, it is vertical and aligned with the limit waist hole 91. When it is rotated another 90 degrees, it is horizontal, forming a locking position, thereby preventing the current transformer 2 from sliding out.

[0034] Example 3

[0035] Furthermore, based on Example 1, the front portion of the first side plate 4 is bent obliquely to form a bent portion 41, and the bent portion 41 is connected to a flat portion 42. In this way, when the current transformer 2 is pulled outward and reaches the bent portion 41, the inner end of the current transformer 2 slides downward along the bent portion 41 until it reaches the flat portion 42, giving the worker a vibration reminder: the current transformer 2 must be pulled out completely, thereby reminding the worker to firmly support the current transformer to prevent the current transformer from suddenly falling and causing the worker to fail to react in time and drop it.

[0036] Chamfers 71 are formed at both ends of the second guide slide 7 to facilitate quick insertion.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
