Description

Technical Field

[0001] The utility model relates to the technical field of instrument transformer installation, in particular to an installation structure of an instrument transformer and an instrument transformer assembly. Background Technique

[0002] The instrument transformer for installation is also called an instrument transformer, which is a device that transforms voltage or current in proportion and is a general term for current transformers and voltage transformers. At the same time, the instrument transformer can also be used to isolate the high-voltage system to ensure the safety of personnel and equipment. The structure of the current transformer is relatively simple and consists of a primary winding, a secondary winding, an iron core, and a frame, a shell, a terminal, etc. that are insulated from each other. Its working principle is basically the same as that of a transformer.

[0003] Existing instrument transformers are generally fixed inside the power distribution cabinet by bolts, which is rather troublesome to disassemble and repair the instrument transformer subsequently. At the same time, if the bolts are lost, it will affect the subsequent installation operation. Content of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the above technical defects.

[0005] Therefore, an object of the utility model is to provide an installation structure of an instrument transformer and an instrument transformer assembly to solve the problems mentioned in the background technique and overcome the deficiencies existing in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the utility model provides an installation structure of an instrument transformer, including a first mounting seat and a second mounting seat connected to the instrument transformer. The first mounting seat is arranged on one side of the second mounting seat. Positioning plates are fixedly connected to both sides of the second mounting seat. A positioning groove penetrating one side of the positioning plate is arranged on the surface of the positioning plate. Two L-shaped moving frames are slidably connected inside the first mounting seat. One end of the L-shaped moving frame penetrates the first mounting seat. A limiting plate for limiting the positioning plate is fixedly connected to one end of the L-shaped moving frame. A lead screw is rotatably connected inside the first mounting seat, and one end of the lead screw penetrates the first mounting seat. A driving rod structure for driving the L-shaped moving frame to move is threadedly connected to the surface of the lead screw. The technical effect achieved by adopting the above scheme is that: by rotating and adjusting to make the lead screw rotate, then the rotation of the lead screw drives the threaded block threadedly connected to it to move. Then the movement of the threaded block makes the rod body rotate through the cooperation between the first hinge seat and the second hinge seat. Then the rotation of the rod body pulls the two L-shaped moving frames to move towards each other, so that the L-shaped moving frames are inserted into the positioning groove. At the same time, one side of the limiting plate contacts one side of the positioning plate. When moving to the corresponding distance, the position of the positioning plate is positioned, and the installation and disassembly operations can be carried out quickly, and at the same time, the inconvenience of subsequent operations caused by the loss of bolts can be avoided.

[0007] Preferably, any of the above schemes is that the driving rod structure includes a threaded block, the threaded block is threadedly connected to the screw rod, first hinged seats are fixedly installed on opposite sides of the threaded block, the middle part of the first hinged seat is rotatably connected to a rod body, one end of the rod body is rotatably connected to a second hinged seat, and the second hinged seat is fixedly installed on one side of the L-shaped movable frame. The technical effect achieved by adopting the above scheme is: the threaded block threadedly connected to it is driven to move by the rotation of the screw rod, and then the movement of the threaded block causes the rod body to rotate through the cooperation between the first hinged seat and the second hinged seat, and then the rotation of the rod body pulls the two L-shaped movable frames to move toward each other.

[0008] Preferably, any of the above schemes is that a groove is provided inside the first mounting seat, and a limiting slide groove longer than the positioning groove is provided on one side of the groove, and the L-shaped movable frame is located inside the limiting slide groove. The technical effect achieved by adopting the above scheme is: the L-shaped movable frame moves inside the limiting slide groove when moving, so that the L-shaped movable frame can be separated from the positioning groove, thereby relaxing the limitation of the positioning plate and facilitating the disassembly operation.

[0009] Preferably, any of the above schemes is that a bearing is fixedly installed on the inner wall of the groove, a screw rod is interference fit in the middle of the bearing, an adjusting handle is fixedly installed on one end of the screw rod, and a storage groove matched with the adjusting handle is provided on one side of the first mounting seat. The technical effect achieved by adopting the above scheme is: one end of the screw rod can be limited by the bearing, so that the screw rod can rotate more stably, and the adjusting handle can be stored by the storage groove, which can effectively reduce the volume of the first mounting seat.

[0010] Preferably, any of the above schemes is that a guide slot is provided on the inner wall of the groove, and a guide slider matched with the guide slot is fixedly installed on one side of the L-shaped movable frame, and the guide slot is slidably connected to the guide slider, and the shapes of the guide slot and the guide slider are both T-shaped. The technical effect achieved by adopting the above scheme is: when the L-shaped movable frame moves, the guide slider slides inside the guide slot, thereby guiding the movement of the L-shaped movable frame, and the movement of the L-shaped movable frame can be made more stable.

[0011] Preferably, any of the above schemes is that an auxiliary positioning plate is fixedly connected to one side of the first mounting seat, and the inner wall of the positioning groove is provided with an auxiliary positioning groove that is compatible with the auxiliary positioning plate. The technical effect achieved by adopting the above scheme is: by aligning the auxiliary positioning groove with the auxiliary positioning plate and inserting it, the lateral movement of the second mounting seat can be preliminarily positioned, so that the L-shaped movable frame can be more conveniently and accurately inserted into the interior of the positioning groove for positioning operations.

[0012] Preferably, according to any of the above solutions, mounting lugs are fixedly installed on both sides of the first mounting base. The inner walls of the two sides of the L-shaped moving frame tangent to the limit chute are arc-shaped. The technical effect achieved by adopting the above solution is that the position of the first mounting base can be fixed through the mounting lugs, and during the subsequent disassembly of the mutual inductor, only by operating the L-shaped moving frame to move can the installation and disassembly operations be completed.

[0013] To achieve the above object, an embodiment of one aspect of the present invention provides a mutual inductor assembly, including a mutual inductor disposed on the top of a second mounting base and an installation structure of the mutual inductor, wherein the installation structure is the mutual inductor installation structure described in any one of the foregoing.
