Description

Technical Field

[0001] The invention relates to the technical field of current transformers, in particular to a fixing device for a current transformer. Background Art

[0002] The current transformer is an instrument that converts the primary side large current into the secondary side small current for measurement based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. Its primary side winding has very few turns and is connected in series in the circuit of the current to be measured. Therefore, it often has the entire current of the circuit flowing through it. The secondary side winding has more turns and is connected in series in the measuring instrument and the protection circuit. When the current transformer is working, its secondary side circuit is always closed, so the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to short circuit. The current transformer converts the primary side large current into the secondary side small current for measurement, and the secondary side cannot be open circuit.

[0032] Embodiment 3 See also Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10On the basis of the first and second embodiments, it is further obtained that the tensioning mechanism 3 includes a regulating component 31, a tensioning component 32 and a stabilizing component 33.

The tensioning component 32 includes a threaded block 3201, which is threadedly connected to the outer ring of the double-axis threaded rod 3102 and is located at the upper and lower sides of the transmission chain 2302. The threaded block 3201 is threadedly connected to the outer ring of the double-axis threaded rod 3102. 01 is fixedly connected to the inner side with a connecting plate 3202, the inner side of the connecting plate 3202 is fixedly connected to a fixed shaft 3203, the outer ring of the fixed shaft 3203 is rotatably connected to a tensioning rod 3204, the outer ring of the tensioning rod 3204 fits with the outer ring of the transmission chain 2302, the stabilizing component 33 includes a lifting slide 3301, the lifting slide 3301 is fixedly connected to the inner side of the fixed shaft 3203, the inner ring of the lifting slide 3301 is slidably connected to a fixed slide rod 3302, the fixed slide rod 3302 is fixedly connected to the top of the fixed box 3101, and the fixed slide rod 3302 is fixedly connected to the top of the base 4.

[0034] Furthermore: the staff only needs to rotate the torsion disk 3103 on the left and right sides to drive the tensioning rods 3204 on the upper and lower sides to move inward or outward synchronously, so that when the device is in use, the staff can adjust the tension of the transmission chains 2302 on the left and right sides, so that when the device is in use, the transmission chain 2302 and the transmission gear 2301 will not be disconnected or loosened due to long-term use, thereby increasing the stability of the device when in use and improving the transmission efficiency of the double-axis threaded rod 2103 on the front and rear sides when the device is in use.

[0035] In actual operation, when the device is used, when the current transformer body 5 needs to be installed, the staff first places the current transformer body 5 on the top of the base 4, so that the bottom of the power connection gasket 51 fits with the top of the base 4, and then the staff moves the threaded slides 1102 on the left and right sides inward, so that the threaded slides 1102 on the left and right sides are clamped in the left and right sides of the power connection gasket 51, and then the staff clamps the panel 1201 in the top of the power connection gasket 51, and finally the staff inserts the bolt 1202 into the inner circle of the panel 1201 and rotates it, and the bolt 1202 rotates on the inner circle of the threaded slide 1102 and moves downward, and the bolt 1202 moves downward through the threaded slide 1102 and is clamped in the base 4, and the installation of the current transformer body 5 is completed at this time; When the bolt 1202 needs to be limited after the current transformer body 5 is installed, the staff only needs to rotate the rocker 2405. The rocker 2405 rotates through the turntable 2404 to drive the shaft 2403 to rotate. The shaft 2403 rotates through the bevel gear 2402 to drive the bevel gear 1 2401 to rotate. The bevel gear 1 2401 rotates to drive the front double-axis threaded rod 1 2103 to rotate. The front double-axis threaded rod 1 2103 rotates through the transmission gear 2301 and the transmission gear 2302. The chain 2302 drives the double-axis threaded rod 2103 on the rear side to rotate, and the double-axis threaded rods 2103 on the front and rear sides rotate synchronously to drive the fixed screw barrels 2102 on the left and right sides to move inward synchronously, and the inward movement of the fixed screw barrel 2102 drives the limit plate 2101 to move inward, and the limit plate 2101 moves inward to the top of the bolt 1202, and then the rocker 2405 stops rotating. At this time, the limit plate 2101 fits with the top of the bolt 1202 to complete the limit processing of the bolt 1202; When it is necessary to adjust the tension of the transmission chain 2302, the staff first rotates the torsion plate 3103. The rotation of the torsion plate 3103 drives the double-axis threaded rod 3102 to rotate. The rotation of the double-axis threaded rod 3102 drives the threaded blocks 3201 on the upper and lower sides to move inward or outward synchronously. The movement of the threaded block 3201 drives the fixed shaft 3203 to move through the connecting plate 3202. The movement of the fixed shaft 3203 drives the tensioning rod 3204 to move. When the threaded blocks 3201 on the upper and lower sides move inward, the tensioning rods 3204 on the upper and lower sides move inward to squeeze the transmission chain 2302 to shrink inward. At this time, the tension of the transmission chain 2302 is increased, and the outward movement of the threaded blocks 3201 on the upper and lower sides drives the tensioning rods 3204 on the upper and lower sides to move outward, thereby relieving the squeezing of the transmission chain 2302 and reducing the tension of the transmission chain 2302.
