Description

Technical Field

[0001] This utility model relates to the field of current transformer technology, and in particular to a current transformer with a fixed wire mechanism. Background Technology

[0002] In the existing technology, current transformers are divided into current transformers (CTs) and voltage transformers (PTs). Their core function is to convert the high voltage or large current on the primary side into a standard low voltage (such as 100V) or small current (such as 5A / 1A) on the secondary side through the principle of electromagnetic induction, so as to adapt to the input requirements of measuring instruments, relay protection and other equipment. In the existing technology, current transformers have low stability and weak control over the coil, which is not conducive to their use.

[0003] Therefore, this application proposes a current transformer with a fixed-wire mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing current transformers, such as low stability and weak control over the coil, which are detrimental to their use. This invention proposes a current transformer with a fixed wire mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A current transformer with a fixed wire mechanism includes a base and a current transformer;

[0007] The connecting base is fixedly connected to the bottom of the current transformer;

[0008] Two hollow movable plates are symmetrically and slidably connected to the top of the base, and vertical plates are slidably connected inside the movable plates;

[0009] A fixed-line ring, which is slidably connected inside the current transformer;

[0010] The control panel is hollow inside and is slidably connected to the top of the base. A pressure plate is slidably connected inside the control panel. The top of the base is provided with a through hole, and the pressure plate is movably connected to the through hole.

[0011] The base is equipped with a positioning mechanism on its top, and the current transformer is equipped with a wire fixing mechanism.

[0012] As a preferred embodiment of this utility model, the positioning mechanism includes two sliding plates, two springs, and two pull plates. The sliding plates are symmetrically slidably connected to the top of the base. The ends of the two springs that are far apart from each other are fixedly connected to the sides of the two sliding plates that are close to each other, and the ends of the two springs that are close to each other are both fixedly connected to the top of the base. The pull plates are rotatably connected to the top of the sliding plates, and the rear side of the pull plates is rotatably connected to the bottom of the adjacent movable plates.

[0013] As a preferred embodiment of this utility model, the top of the control plate is symmetrically rotatably connected to two push plates, and the ends of the two push plates that are far apart from each other are rotatably connected to the top of the adjacent sliding plate.

[0014] As a preferred embodiment of this utility model, the wire fixing mechanism includes two extension plates, two hollow plates, and two locking plates. The extension plates are fixedly connected to the rear side of the wire fixing ring, and the rear side of the extension plates passes through the current transformer. The hollow plates are symmetrically fixedly connected to the rear side of the current transformer, and the hollow plates are provided with multiple locking holes. The locking plates are fixedly connected to the rear side of the extension plates, and the rear side of the locking plates is inclined. The locking plates are movably connected to the locking holes of adjacent hollow plates.

[0016] As a preferred embodiment of this utility model, the locking plate is made of PP plastic with resilience properties.

[0017] Beneficial effects:

[0018] 1. By inserting the connector with the current transformer into the base, the control board can be moved by pushing it. The control board can also push the push plate to move synchronously. When the push plate moves, it pushes the two sliding plates away from each other. At this time, the movement of the sliding plates can pull the pull plate to move.

[0019] 2. As the pull plate moves, it can pull the two movable plates forward. At this time, the movement of the movable plates can synchronously control the movement of the vertical plate. When the vertical plate is matched with the vertical groove of the connecting seat, the vertical plate descends and connects with the vertical groove, thereby restricting the movement of the connecting seat. At the same time, the control plate drives the pressure plate to connect with the through hole, locking the entire device and realizing the rapid installation of the current transformer, thereby ensuring stability.

[0020] 3. After the current transformer is wired, the wire fixing ring is pushed backward to make contact with the coil. At the same time, the locking plate is connected to the hollow plate through the inclined surface to achieve the effect of fixing the coil wire, which is convenient to use.

[0021] In this invention: by inserting the connector with the current transformer into the base, and by pushing the control board to move it, the control board can assist the vertical plate in connecting with the vertical slot, thereby fixing the connector and locking the entire device, realizing the quick installation of the current transformer and ensuring stability. At the same time, by pushing the wire-fixing ring to move it, the wire-fixing ring contacts the coil. Meanwhile, the locking plate is connected to the hollow plate through the inclined surface, achieving the effect of fixing the coil wire, which is convenient to use. Attached Figure Description
