Sensitive component test system of protection relay

Abstract

The invention discloses a sensitive component test system of a protection relay. The structure of the system comprises a motor, a holding plate, a holding layer, a stop block, a blanking rod and a lifting column, wherein the two sides of the motor are connected with the holding plate through the lifting column, the holding plate is provided with the stop block, the holding plate is connected with the holding layer and the blanking rod, the stop block comprises a side bearing platform, a sliding plate, a through groove, a positioning claw and a connecting plate, the bottom of the side bearing platform is in sliding fit with the motor through a sliding plate and is connected with a connecting plate, the connecting plate is connected with a through groove, a positioning claw is arranged in the through groove, a carrying device and a pressure rotating structure are arranged on the positioning claw, the carrying device and the pressure rotating structure are matched with a covering cover, when downward guiding wires of the blanking rod is constantly intermingled outside device, the wires can be tensioned and dragged in the same direction along the edge of the carrying device and then are turned and gathered side by side through a turning and pressing structure, so that the edge rolling effect of the wires is guaranteed.

Description

technical field [0001] The invention relates to the field of sensitive components, in particular to a sensitive component testing system for a protective relay. Background technique [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...

[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
