[0015] The present invention also discloses a line detection method for transformer substation relay protection, which specifically comprises the following steps: S1. After the storage assembly is moved to the substation line inspection point through the grip rod and the pulley, the second electric telescopic rod is started. The extended end of the second electric telescopic rod drives the reinforcement pad to move downward until the reinforcement pad is firmly in contact with the ground. The reinforcement pad descends and drives the toothed plate to descend. The toothed plate descends and meshes with the gear. The meshing of the gears synchronously drives the rotating shaft to rotate. The rotating shaft drives the pulley and the belt transmission to cooperate. The pulley and the gear transmission cooperate to synchronously drive the rotating rod to rotate. The rotating rod drives the protective cover to flip. When the reinforcement pad contacts the ground, the corresponding protective cover flips backward 180 degrees. S2. When the protective cover plate flips backward, it drives the auxiliary pressing plate to rotate synchronously. When the auxiliary pressing plate rotates 90 degrees, its inclined surface will contact the end of the vertical rod, and as the auxiliary pressing plate continues to flip backward, the auxiliary pressing plate will press down the vertical rod. The vertical rod descends and drives the U-shaped frame to move downward. The U-shaped frame drives the pressure rod to move downward. The downward movement of the pressure rod will press down the guide inclined plate. The guide inclined plate is forced to drive the anti-sway card frame to move forward. The anti-sway card frame moves forward and its inner cavity top retaining edge will separate from the multi-telescopic insulating sleeve rod and break away from the limit enclosure cooperation. S3, the anti-sway card frame moves forward and synchronously drives the trapezoidal inclined block to move. The inclined surface of the trapezoidal inclined block will be squeezed with the surface of the multi-telescopic insulating sleeve rod, causing the multi-telescopic insulating sleeve rod to start turning upward from left to right with the rotating axis as the rotation angle. As the trapezoidal inclined block moves by squeezing, the arc groove on the top of the trapezoidal inclined block is finally forced to fit with the drag reduction sleeve. At this time, the raised end of the corresponding multi-telescopic insulating sleeve rod is lifted to the top of the storage assembly; S4. The multi-telescopic insulating sleeve is flipped and drives the rotating shaft to rotate at the same time. After the multi-telescopic insulating sleeve is flipped to a certain angle, the corresponding rotating shaft stops rotating. At this time, the polygonal groove opened on the surface of the front rotating shaft is aligned with the polygonal plug-in shaft. Then, the first electric telescopic rod is started. The first electric telescopic rod is started and its extended end drives the L-shaped mounting plate and the driving motor to move backward. The driving motor moves backward and drives the polygonal plug-in shaft to fit with the polygonal groove. Then, the driving motor is started to drive the polygonal plug-in shaft and the rotating shaft to make the final adjustment to the electrical testing angle of the multi-telescopic insulating sleeve. After the angle adjustment is completed, the multi-section insulating sleeve rods inside the multi-telescopic insulating sleeve can be pulled out one by one.

[0016] As a preferred solution of the line detection method for relay protection of a substation of the present invention, wherein: a limiting slide groove which is slidably matched with the U-shaped frame is provided on the rear side of the storage component in S2 The beneficial effects of the present invention are as follows: (1) The line detection device and use method for remotely deployed relay protection of the substation, by rotating and setting the multi-telescopic insulating sleeve rod inside the storage component, and arranging the first electric telescopic rod, the driving motor, the polygonal plug shaft, the rotating shaft and the polygonal groove between the storage component and the multi-telescopic insulating sleeve rod, so that the rotation test support angle of the multi-telescopic insulating sleeve rod is easy to hold, thereby reducing the labor intensity; secondly, a stabilizing deployment component, a limit self-releasing component and a lifting component are arranged between the storage component and the multi-telescopic insulating sleeve rod, so that the device can automatically reinforce the device and automatically deploy the covering protection on the top of the multi-telescopic insulating sleeve rod through the coordinated cooperation of the stabilizing deployment component, the limit self-releasing component and the lifting component, and simultaneously and automatically release the anti-sway limit protection of the multi-telescopic insulating sleeve rod and simultaneously slightly lift the angle of the multi-telescopic insulating sleeve rod, so that the multi-telescopic insulating sleeve rod and the end of the tester are automatically lifted to the top of the storage component.

[0017] (2) The line detection device and use method for remotely deployed relay protection of the substation, by rotating and setting a drag reducing sleeve on the surface of a multi-telescopic insulating sleeve rod, can reduce the friction resistance between the trapezoidal inclined block and the multi-telescopic insulating sleeve rod by the rotation performance of the drag reducing sleeve when the trapezoidal inclined block and the multi-telescopic insulating sleeve rod are squeezed and matched.

[0018] (3) The substation remotely deployed relay protection line detection device and its use method, by arranging an auxiliary pressure plate on the top of the protective cover, so that when the protective cover is flipped and pressed with the vertical rod, the vertical rod can be pressed down by the inclined surface of the auxiliary pressure plate, making it easier for the protective cover to vertically press the vertical rod.

9. A method for a line detection device for relay protection of a substation according to claims 1 to 8, characterized in that: The specific steps include: S1. After the storage assembly (100) is moved to the substation line detection point by means of the gripping rod and the pulley, the second electric telescopic rod (201) is started, and the extension end of the second electric telescopic rod (201) drives the reinforcement pad (202) to move downward until the reinforcement pad (202) is firmly in contact with the ground, and the reinforcement pad (202) descends and drives the toothed plate (207) to descend, and the toothed plate (207) descends and meshes with the gear (206), and the meshing of the gear (206) synchronously drives the rotating shaft (203) to rotate, and the rotating shaft (203) drives the pulley (204) and the belt (205) to cooperate in transmission, and the pulley (204) and the gear (206) cooperate in transmission to synchronously drive the rotating rod (106) to rotate, and the rotating rod (106) drives the protective cover plate (107) to flip, and when the reinforcement pad plate (202) is in contact with the ground, the corresponding protective cover plate (107) flips backward 180 degrees; S2. During the backward flipping process of the protective cover plate (107), the auxiliary pressing plate (307) is synchronously driven to rotate. When the auxiliary pressing plate (307) rotates 90 degrees, its inclined surface will contact the end of the vertical rod (306), and as the auxiliary pressing plate (307) continues to flip backward, the auxiliary pressing plate (307) will press down the vertical rod (306). The vertical rod (306) will move downward and drive the U-shaped frame (303) to move downward. The U-shaped frame (303) drives the pressure rod (304) to move downward. The downward movement of the pressure rod (304) will press down the guide inclined plate (302). The guide inclined plate (302) is forced to drive the anti-sway card frame (301) to move forward. When the anti-sway card frame (301) moves forward, the top retaining edge of its inner cavity will separate from the multi-telescopic insulating sleeve rod (104) and break away from the limit enclosure cooperation; S3, the anti-sway card frame (301) moves forward and synchronously drives the trapezoidal inclined block (401) to move. The inclined surface of the trapezoidal inclined block (401) moves and squeezes the surface of the multi-telescopic insulating sleeve rod (104), prompting the multi-telescopic insulating sleeve rod (104) to start turning upward from left to right with the rotating shaft (103) as the rotation angle. As the trapezoidal inclined block (401) moves by squeezing, the arc-shaped groove (403) at the top of the trapezoidal inclined block (401) is finally forced to fit with the drag reduction sleeve (402). At this time, the raised end of the corresponding multi-telescopic insulating sleeve rod (104) is lifted to the top of the storage assembly (100); S4, the multi-telescopic insulating sleeve rod (104) flips and drives the rotating shaft (103) to rotate at the same time. After the multi-telescopic insulating sleeve rod (104) flips to a certain angle, the corresponding rotating shaft (103) stops rotating. At this time, the polygonal groove (108) provided on the surface of the front rotating shaft (103) is aligned with the polygonal plug shaft (112). Then, the first electric telescopic rod (109) is started. The first electric telescopic rod (109) starts its extended end to drive the L-shaped mounting plate (110) and the driving motor (111) to move backward. The driving motor (111) moves backward to drive the polygonal plug shaft (112) to fit with the polygonal groove (108). Then, the driving motor (111) is started to drive the polygonal plug shaft (112) and the rotating shaft (103) to finally adjust the electrical testing angle of the multi-telescopic insulating sleeve rod (104). After the angle adjustment is completed, the multiple insulating sleeve rods inside the multi-telescopic insulating sleeve rod (104) are pulled out in sequence.

10. A substation relay protection line detection method according to claim 9, characterized in that: The rear side of the storage assembly (100) in S2 is provided with a limiting sliding groove slidably matched with the U-shaped frame (303).
