Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a current transmitter suitable for high voltage. Background Art

[0002] Power engineering usually refers to engineering related to the production, transmission and distribution of electric energy, and also includes the application of electric energy in various fields. Among them, current transmitter is a commonly used device used to convert current signals into standard signals for long-distance transmission and processing.

[0003] After searching, the patent number is CN218675124U, and the name is a utility model of a current transmitter suitable for high voltage, which includes a placement tube with an opening at one end. Through research and analysis, it is found that although the design of through holes, vias and semi-permeable membranes can ensure ventilation to a certain extent, the following disadvantages still exist to a certain extent.

[0004] For example, in actual applications, current transmitters often need to be assembled and installed with multiple cables for connection with other electrical equipment. This device only stores and positions the current transmitter, which cannot meet the cable installation requirements. In addition, due to the uncertain storage quantity, the actual installation quantity of cables also varies, which has certain limitations. In order to solve the above technical problems, we have designed a current transmitter suitable for high voltage. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model has the advantage of flexible assembly by arranging a wire sealing mechanism. In a number of current transmitter installation states, the angle of the damping rotating ring can be changed, and the number of overlaps between the second sealing hole and the first sealing hole can be adjusted, thereby meeting the external space requirements for different numbers of cables.

[0019] See also Figure 1-Figure 4, a current transmitter suitable for high voltage, including a rear storage tube 1 and a front storage tube 3. By setting the rear storage tube 1 and the front storage tube 3, it can meet the storage and installation requirements of multiple current transmitters in a docking installation state, and ensure the overall sealing and moisture-proof performance. A mounting bracket 6 is fixedly installed on the rear side of the inner cavity of the rear storage tube 1. By setting the mounting bracket 6, it can meet the installation requirements of multiple current transmitters. The top and bottom of the rear storage tube 1 and the front storage tube 3 are fixedly connected with a mounting seat 5. The surface of the mounting seat 5 is penetrated and installed with a mounting member 2. By setting the mounting member 2 and the mounting seat 5, the rear storage tube 1 and the front storage tube 3 can be stably installed in the installation state. The left and right sides of the rear storage tube 1 are fixedly installed with a wire sealing mechanism 4. The tops of the rear storage tube 1 and the front storage tube 3 are fixedly inlaid with a sealing strip 7. By setting the sealing strip 7, the installation sealing between the rear storage tube 1 and the front storage tube 3 can be ensured in the installation state.

[0020] See also Figure 3 and Figure 4 The wire sealing mechanism 4 includes a fixing plate 401, a breathable mesh plate 403 is fixedly connected to the surface of the fixing plate 401 and is located in the inner cavity of the rear storage cylinder 1, and the inner cavity of the breathable mesh plate 403 is filled with a desiccant 408. By arranging the breathable mesh plate 403 and the desiccant 408, the breathable mesh plate 403 can store the desiccant 408, and then the desiccant 408 can absorb moisture in the rear storage cylinder 1 and the front storage cylinder 3;

[0021] See also Figure 3 and Figure 4 A first sealing hole 404 is formed through the surface of the fixed plate 401, and a convex plate 402 is fixedly connected to one side of the fixed plate 401 away from the breathable mesh plate 403. By providing the convex plate 402, the space requirement for the T-shaped ring groove 410 can be met;

[0022] See also Figure 3 and Figure 4 The outer ring and the inner ring of the convex plate 402 are both provided with a T-shaped ring groove 410, and a rotation groove 409 is provided between two adjacent T-shaped ring grooves 410. By providing the rotation groove 409, the installation space requirement of the damping rotation ring 407 can be met;

[0023] See also Figure 3 and Figure 4 The inner cavity of the rotating groove 409 is rotatably mounted with a damping rotating ring 407, and the outer ring of the damping rotating ring 407 is fixedly connected with a T-block 406, and the T-block 406 is adapted to the T-ring groove 410. By setting the T-block 406 and the T-ring groove 410, a positioning and guiding function can be played, and the rotation stability of the damping rotating ring 407 can be effectively improved, and the damping rotating ring 407 can be prevented from being displaced and separated from the convex plate 402;

[0024] See also Figure 3 and Figure 4 A second sealing hole 405 is formed through the surface of the damping rotating ring 407, and the second sealing hole 405 is matched with the first sealing hole 404. By providing the first sealing hole 404 and the second sealing hole 405, the cable penetration installation space requirement can be met in an aligned state;

[0025] The mounting member 2 includes a sealing bolt and a sealing nut. The sealing bolt passes through the mounting seat 5 and is threadedly connected to the sealing nut. A sealing ring is embedded and installed between the front and rear mounting seats 5.

[0026] The fixing plate 401 and the rear storage tube 1, as well as the fixing plate 401 and the front storage tube 3 are fixedly connected by detachable bolts and sealed;

[0027] The first sealing hole 404 and the second sealing hole 405 are both composed of a through hole and a rubber ring. The rubber ring is fixedly installed in the through hole to ensure the sealing performance when the cable is installed, and to prevent external moisture or impurities from entering the rear storage tube 1 and the mounting member 2. At the same time, the rubber ring is made of elastic material and can be suitable for the installation requirements of cables of different thicknesses within a certain range, and ensure installation stability.

[0028] When in use, all components are in the initial state. First, multiple current transmitters are fixedly installed on the mounting frame 6 with bolts. Then, according to the actual wiring requirements, the damping rotating ring 407 at the corresponding position is selected, and the damping rotating ring 407 is driven to rotate so that the first sealing hole 404 is aligned with the second sealing hole 405. At this time, the cable penetration installation space requirements can be met for the installation of multiple cables. Then, the front storage cylinder 3 is docked with the rear storage cylinder 1, and fixed with the mounting member 2 and the mounting seat 5. Then, the fixing plate 401 is fixedly installed on the rear storage cylinder 1 and the front storage cylinder 3. The breathable mesh plate 403 and the desiccant 408 are located in the rear storage cylinder 1 and the front storage cylinder 3 to ensure that the internal environment of the rear storage cylinder 1 and the front storage cylinder 3 is dry. Since the rear storage cylinder 1 and the front storage cylinder 3 are split designs, it is greatly convenient to assemble multiple current transmitters, and it is also convenient to install the cables through the wire sealing mechanism 4.

[0029] In summary: the current transmitter suitable for high voltage, by setting the wire sealing mechanism 4, solves the problem that the device only stores and positions the current transmitter and cannot meet the cable installation requirements well, and because the storage quantity is uncertain, the actual installation quantity of cables also varies, which has certain limitations.
