Description

Technical Field

[0001] This utility model relates to the field of current transformers, and more particularly to the housing of a CT current transformer. Background Technology

[0002] Current transformers, often simply called CT transformers, are widely used measurement and protection devices in power systems. These devices operate based on the principle of electromagnetic induction, and their main function is to convert the current in a high-current system into a low-current system according to a certain ratio. Through this conversion, current measurement, protection, and control equipment can be easily connected, thereby ensuring the safe and stable operation of the power system.

[0003] There is currently a Chinese patent document CN202323099586.5 describing a current transformer housing and a current transformer, including a mounting plate. A receiving box is fixedly mounted on the top of the mounting plate, and a housing is provided on the receiving box. The housing is covered with a cover, and a limiting structure is provided inside the housing to fix the position of the housing. By setting the limiting structure, the housing can be installed or disassembled quickly and effectively, facilitating timely maintenance of the internal equipment by the staff. In use, the staff presses two fixed blocks, and two connecting rods move closer to each other. The movable block at the bottom of the connecting rod slides inside the slide groove. By setting the movable block, the connecting rod can be guided and supported. The two connecting rods push the guide rod to rotate, and the guide rod tends to be perpendicular to the guide rail. At the same time, the fixed rod slides into the fixed cylinder, and the return spring inside the fixed cylinder deforms to generate elastic potential energy. Then the housing is placed on the receiving box, and the pressure on the fixed blocks is released.

[0004] However, the above-mentioned patent has certain defects in use. Since the position of the current transformer housing cannot be adjusted when it is installed with external equipment, it can only be fixed through the mounting holes, resulting in insufficient installation flexibility and difficulty in adapting to the installation needs of different equipment.

[0005] To address these issues, a CT transformer housing is proposed here. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a CT transformer housing.

When installing the ring, simply align the first mounting groove on the ring with the first positioning hole of the positioning component and gently push it in. When the first positioning block reaches the end of the first mounting groove, it then slides into the first sliding groove to achieve precise positioning. Installation can be completed without additional tools, simplifying the operation process and improving work efficiency.

[0019] 3. When installing the cover plate, the second positioning block is precisely aligned with multiple second mounting slots on the inner wall of the housing. When the second positioning block reaches the end of the second mounting slot, it slides into the second sliding groove to quickly lock the cover plate. Then, the bolts are tightly screwed into the threaded post to ensure that the cover plate is stable and not loose. Attached Figure Description
