Problems solved by technology

[0002] Overcurrent and grounding protection relay series cards are important cards for nuclear power plant circuit protection, mainly used in radial power grids with direct grounding, resistance grounding or impedance grounding in power systems, including power boards, main boards and relay boards, of which the main board and The relay board is equipped with components that play a major role in relay overcurrent protection, including sensitive components such as capacitors, relays, and current transformers. The existing sensitive component testing system for protective relays is used to roll the wires outside the device. When it is round, in order to tighten the coiled circle, semicircle or arc of any angle outside the device, it will use the downward guidance of the feeding rod to continuously intertwine to the outside of the device to change the diameter of the device itself, so that Adjacent wires overlap with each other, so that the tension strength is weak after the wires are rounded, causing the adjacent wires to be loose and messy, and even extend out of the equipment in a curled form, reducing the effect of wire rounding

Embodiment 1

[0026] Such as Figure 1-Figure 3 As shown, the present invention provides a sensitive component testing system of a protective relay, and its structure includes a motor 1, a clamping plate 2, a cover layer 3, a stopper 4, a feeding rod 5, and a lifting column 6. The motor 1 has two The side is hingedly connected with the clamping plate 2 by the lifting column 6, and the top is provided with a stopper 4, and the inner side of the clamping plate 2 is fixedly connected with a cover layer 3 and a blanking rod 5, and the stopper 4 includes a side bearing platform 41, Sliding plate 42, through groove 43, positioning claw 44, connecting plate 45, the bottom of the side platform 41 is slidably fitted on the motor 1 through the sliding plate 42, and the top is fixedly connected with connecting plate 45, and the connecting plate 45 is welded and connected with Through groove 43, described through groove 43 is provided with positioning claw 44, and described positioning claw 44 comprise...

Embodiment 2

[0028] Such as Figure 4-Figure 7 As shown, on the basis of Embodiment 1, the present invention combines the mutual cooperation of the following structural components. The carrying device 442 includes a final shaft 2a1, an insert sleeve 2a2, a top shoulder 2a3, a spacer hook 2a4, and a clamping rod 2a5. The final shaft 2a1 It is rotated and fitted between the clamping rods 2a5, and the clamping rods 2a5 are inserted and connected in the insertion sleeve 2a2. The insertion sleeve 2a2 is fixedly connected to the bottom of the spacer hook 2a4, and is indirectly fitted together with the top shoulder 2a3. The spacer hook 2a4 arc The two sides of the shape are transitionally fitted with the warhead 446, and the bend is socketed and connected to the back of the cover 444, which can effectively guide the rounded wire to be tightened and shaped, and restrict the traveling direction of the spacer hook 2a4. The top shoulder 2a3 includes Rubber ring a31, reinforcing groove a32, ball a33, ...
