Description

Technical Field

[0001] This application relates to the field of current transformer technology, and more specifically to an integrated transformer housing. Background Technology

[0002] The function of a current transformer is to convert a large primary current into a smaller secondary current through a certain transformation ratio, which is used for protection and measurement purposes. Different specifications of current transformers are available depending on the installation location and the object being installed. Current transformers are widely used due to their relatively simple structure.

[0003] Chinese patent document CN221101812U discloses a current transformer housing and a current transformer, and specifically discloses a mounting plate. A receiving box is fixedly installed on the top of the mounting plate, and a housing is provided on the receiving box. The housing is provided with a cover. A limiting structure is provided inside the housing, and the limiting structure is used to fix the position of the housing. By setting the limiting structure, the housing can be installed or disassembled quickly and effectively, which facilitates the timely maintenance of the equipment inside the housing by the staff.

[0004] However, in the aforementioned patent, the mounting plate is a flat structure, which has high requirements for the mounting surface. When the wiring inside the electrical cabinet is complex, the existing mounting plate is difficult to install stably and cannot adapt to complex site conditions. Utility Model Content

[0005] To overcome the problem that existing instrument transformer housings are difficult to adapt to complex installation environments, this application provides an integrated instrument transformer housing.

[0006] This application adopts the following technical solution: an integrated current transformer housing, including a main housing and a mounting plate. The main housing is annular, and a through hole is provided in the middle of the main housing. The line to be tested passes through the through hole, and the mounting plate is located at the bottom of the main housing.

[0007] Each of the two side walls of the mounting plate is provided with a first slot, and the bottom of the mounting plate is provided with a plurality of second slots. A movable strip can be inserted into any of the first slots or second slots. The movable strip is used to extend the length, width or thickness of the mounting plate.

[0008] Optionally, the main housing is further provided with wiring terminals, and the mounting plate is provided with mounting holes.

[0009] Optionally, one side of the movable strip is provided with an insert, and the other side of the movable strip is provided with a third slot. The first slot, the second slot, and the third slot are all dovetail-shaped, and the insert can be adapted to be inserted into the first slot, the second slot, or the third slot.

[0010] Optionally, the length of the movable strip is the same as the width of the mounting plate, and the thickness of the movable strip is the same as the thickness of the mounting plate.

[0011] Optionally, a pair of first slots provided on the side wall of the mounting plate extend along the width direction of the mounting plate;

[0012] A plurality of second slots located at the bottom of the mounting plate are spaced apart along the length of the mounting plate.

[0013] Optionally, the second slot is misaligned with the mounting hole.

[0014] Compared with existing technologies, this application ensures that the length, width, thickness and tilt angle of the mounting plate can be precisely and conveniently adjusted through the integrated and detachable assembly of several movable strips and the mounting plate, thus adapting to complex installation environments to the greatest extent.

[0020] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] like Figure 1-4As shown, the integrated current transformer housing includes a main housing 1 and a mounting plate 2. The main housing 1 is annular, with a through hole 11 in the middle. The circuit to be tested passes through the through hole 11. The mounting plate 2 is located at the bottom of the main housing 1. Each of the two side walls of the mounting plate 2 has a first slot 21, and the bottom of the mounting plate 2 has several second slots 22, which are offset from the mounting holes 23. A movable strip 3 can be inserted into any of the first slots 21 or second slots 22. The movable strip 3 is used to extend the length, width, or thickness of the mounting plate 2.

[0022] In the factory-shipped state, all the movable strips 3 can be placed on a pair of side walls of the mounting plate 2, so that the movable strips 3 are flush with the mounting plate 2, that is, the mounting plate 2 and the movable strips 3 form a flat plate with high flatness, which facilitates transportation and packaging. During the installation process, the movable strips 3 can be removed from the first slot 21 of the mounting plate 2 and then inserted into the second slot 22 of the mounting plate 2, thereby covering the height of the mounting plate 2. Furthermore, by selecting different second slots 22 to insert the movable strips 3, the tilt angle of the mounting plate 2 can be changed, thereby adapting to complex installation environments. That is to say, by inserting the movable strips 3 into different first slots 21 or second slots 22, the length, width, thickness and tilt angle of the mounting plate 2 can be changed, maximizing its adaptability to complex installation environments and ensuring that the main housing 1 is in a reliable installation state.

[0023] The main housing 1 is also equipped with a terminal block 12, and the mounting plate 2 is equipped with a mounting hole 23. The terminal block 12 can be used to connect components and measuring components inside the main housing 1, thereby realizing the current detection and monitoring of the circuit to be tested. By screwing bolts into the mounting holes 23, the mounting plate 2 can be fixed to the mounting position inside the electrical cabinet, thereby fixing the main housing 1. Furthermore, since the mounting holes 23 and the second slot 22 are staggered, interference between the bolts and the corresponding movable strips 3 can be effectively prevented.

[0024] One side of the movable strip 3 is provided with an insert 31, and the other side of the movable strip 3 is provided with a third slot 32. The first slot 21, the second slot 22, and the third slot 32 are all dovetail-shaped. The insert 31 can be adapted to be inserted into the first slot 21, the second slot 22, or the third slot 32. When the insert 31 is inserted axially into the first slot 21, the second slot 22, or the third slot 32, the movable strip 3 cannot fall radially out of the first slot 21, the second slot 22, or the third slot 32, thus improving the installation reliability of the movable strip 3. Furthermore, when two movable strips 3 need to be mated together, the insert 31 of one movable strip 3 can be inserted into the third slot 32 of the other movable strip 3. In this way, when one or more movable strips 3 are inserted on one side of the bottom of the mounting plate 2 and two or more movable strips 3 are inserted on the other side of the bottom of the mounting plate 2, the mounting plate 2 will be in an inclined state. When two movable strips 3 are inserted into the same second slot 22 at the bottom of the mounting plate 2, the overall width of the mounting plate 2 increases; when one movable strip 3 is inserted into the first slot 21, the length of the mounting plate 2 increases.

[0025] The length of the movable strip 3 is the same as the width of the mounting plate 2, and the thickness of the movable strip 3 is the same as the thickness of the mounting plate 2. A pair of first slots 21 located on the side wall of the mounting plate 2 extend along the width direction of the mounting plate 2, and several second slots 22 located at the bottom of the mounting plate 2 are spaced apart along the length direction of the mounting plate 2. This allows for more precise adjustment of the position of the movable strip 3, thereby improving the adaptability of the mounting plate 2 to different installation environments. Furthermore, the integrated design of the mounting plate 2 and the several movable strips 3 improves assembly reliability and prevents them from falling off during transportation.

[0026] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
