[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0030] Combination Figures 1-3 A high-precision, wide-range current transformer with a busbar fixing mechanism includes a mounting base 1 and a transformer body 2 detachably mounted on the top of the mounting base 1. A connecting plate 111 is also detachably mounted on the top of the mounting base 1. The mounting base 1 is provided with a disassembly mechanism for maintenance operations on the transformer body 2 and the connecting plate 111. The disassembly mechanism includes a placement slot 11 on the top of the mounting base 1 and a second placement slot 12 on the top of the mounting base 1. A wiring slot 13 is provided on one side of the connecting plate 111. A baffle 131 is fixedly connected to one side of the connecting plate 111. A knob 21 is provided on one side of the transformer body 2, and multiple sets of knobs 21 are provided.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the problem that existing current transformers are often fixedly mounted on their connectors, making disassembly and subsequent maintenance difficult when the transformer is damaged, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, the connecting plate 111 slides into the placement groove 11. A threaded groove 112 is provided on one side of the connecting plate 111. A bolt 113 is threaded onto one side of the mounting base 1. Multiple sets of bolts 113 and threaded grooves 112 are provided, and bolts 113 and 112 are matched. The transformer body 2 slides into the placement groove 12. A bolt 221 is threaded onto the other end of the mounting base 1. A threaded groove 222 is provided on one side of the transformer body 2, and this groove matches bolt 221. During use, the cable can be connected to the electrical connection block 22 via the connecting mechanism. When the transformer body 2 is damaged, the bolt 221 located on one side of the mounting base 1 is rotated, causing the cable to rotate and thus... One end of bolt 121 is dislodged from the inside of the threaded groove 122 on the transformer body 2. At this time, the transformer body 2 can be removed from the mounting base 1. Bolt 113 located on the mounting base 1 can also be rotated. After bolt 113 is rotated, one end of it is dislodged from the inside of the threaded groove 112 on the connecting plate 111, and maintenance operations can be performed. When it is necessary to install the connecting plate 111 and the transformer body 2, the connecting plate 111 and the transformer body 2 are installed in the placement groove 11 and the placement groove 12 respectively. Then, bolt 113 and bolt 121 are rotated in the opposite direction to complete the installation operation of the transformer body 2. This realizes the function of making it convenient for the staff to remove the transformer body 2 separately for maintenance operations, thus improving the usage effect.

[0034] Example 2:

[0035] To address the problem that most existing current transformers have a simple structure, making it inconvenient to classify and connect busbars during use, thus affecting user efficiency, this embodiment discloses the following technical solution, specifically as follows: Figures 3-5As shown, a knob 132 is rotatably connected to one side of the connecting plate 111. Multiple knobs 132 are provided. One end of the knob 132 is fixedly connected to a lead screw 133. A sliding block 134 is threadedly connected to the outer side of the lead screw 133. The sliding block 134 is slidably connected inside the connecting plate 111. A clamping ring 135 is fixedly connected to one side of the sliding block 134. A lead screw 211 is threadedly connected to one side of the transformer body 2. The lead screw 211 is fixedly connected to the knob 21. A fixing block 212 is rotatably connected to one side of the lead screw 211. The fixing block 212 is slidably connected to the transformer body 2. An electrical connection block 22 is fixedly connected to the other side of the transformer body 2. When wiring is required, the cable to be connected can be inserted into the wiring slot 13 on the connecting plate 111, and... One end of the wire passes through the clamping ring 135 and is then connected to the fixing block 212. When the wire needs to be fixed, the knob 132 on the connecting plate 111 can be rotated. The knob 132 drives the lead screw 133 to rotate, which in turn moves the sliding block 134. The sliding block 134 drives the clamping ring 135 to move, which in turn moves the clamping ring 135 to the inside of the connecting plate 111, thereby fixing the wire externally. Then, the knob 21 is rotated, which drives the lead screw 211 to rotate, which in turn makes the fixing block 212 slide on one side of the transformer body 2. At this time, the fixing block 212 can tightly fit one end of the wire with the electrical connection block 22, preventing the wire end from falling off. This makes it easier to fix multiple sets of busbars and improves the efficiency of use.
