[0002] High-voltage power supply refers to the safe, reliable, continuous and qualified sale of electric energy to the majority of power customers through high-voltage transmission and distribution equipment. Relay protection is a relay protection composed of microcomputers or microprocessors. The stable operation of the power system is a prerequisite for ensuring the continuous and reliable supply of electric energy. Relay protection equipment is needed to ensure that the fault is cut off in time or effectively controlled in the shortest time and smallest area. Most of the current relay protection equipment is placed in the working area. However, when encountering rainy weather at work, dust in the air and rainwater are easy to accumulate on the surface of the display screen, and long-term operation is easy to cause damage to the relay protection equipment. Utility Model Content

[0007] As a further solution of the utility model: a guide rod is connected inside the connecting plate, and the clamping plate is rotatably connected outside the guide rod.
[0008] As a further solution of the utility model: a coil spring is connected to the outer shell of the guide rod, and the clamping plate is connected to the guide rod through the coil spring.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. The relay protection device of the high-voltage power supply system places the shell in an appropriate position by arranging a table, a connecting plate, a device body, a card plate, a protrusion, a fixing rod and a slot. When the turntable is driven by a motor to rotate, the protrusion will contact the contact plate, and the connecting plate will drive the table to move in the shell. When the connecting plate moves to the appropriate position, the card plate will overlap in the slot through the action of a coil spring, and then the device body is placed in the groove. When the turntable rotates, the fixing rod on the surface contacts the L-shaped plate, and the connecting plate will drive the table to recover. The relay protection device can achieve the function of height adjustment in the shell through the cooperation between the turntable, the card plate and the slot, so as to avoid dust and rainwater in the air from accumulating on the surface of the display screen, prevent the relay protection device from being damaged, and the table and the shell can form a simple workbench after being fitted.
[0011] 2. The relay protection device of the high-voltage power supply system is provided with a guide rod and a coil spring. When the card plate moves on the side of the sleeve plate, the card plate will rotate with the guide rod as the center, and the card plate will drive the coil spring to deform, so that the guide rod and the coil spring play a certain limiting role for the card plate, thereby avoiding the phenomenon of the card plate getting stuck when rotating.
[0012] 3. The relay protection device of the high-voltage power supply system is provided with a sleeve plate. When the surface protrusion of the turntable contacts the contact plate when the turntable rotates, the contact plate drives the connecting plate to slide in the sleeve plate, so that the sleeve plate plays a certain guiding role for the connecting plate, thereby avoiding the phenomenon of dislocation of the connecting plate when moving.

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0019] like Figure 1-4 As shown, the utility model provides a technical solution: a relay protection device of a high-voltage power supply system, comprising a shell 1, a table 3 is slidably connected in the shell 1, sleeve plates 2 are connected on both sides of the shell 1, a connecting plate 4 is slidably connected in the sleeve plate 2, a groove 5 is provided in the table 3, a device body 6 is overlapped in the groove 5, a rotating rod 7 is rotatably connected in the shell 1, the connecting plate 4 is connected to the table 3, and a motor 9 is connected to one end of the rotating rod 7. By setting the table 3, when the device body 6 is placed in the table 3, the table 3 will be hidden in the sleeve plate 2, and the table 3 and the shell 1 can form a simple workbench after being fitted, which effectively ensures the flexibility of the relay protection device;
[0020] One end of the rotating rod 7 is connected to a rotating disk 8, a card slot 17 is provided in the sleeve plate 2, a card plate 12 is rotatably connected to the side of the connecting plate 4, one side of the connecting plate 4 is connected to a contact plate 14, and the contact plate 14 is overlapped outside the rotating disk 8. By setting the card plate 12 and the card slot 17, when the connecting plate 4 is moved to an appropriate position, the card plate 12 will be clamped in the card slot 17, so as to play a certain positioning role for the table plate 3 after the movement, and prevent the table plate 3 from falling off after the movement;
[0021] The card plate 12 is connected to an L-shaped plate 13 on the outside, the turntable 8 is connected to a protrusion 10 on the outside, and a fixing rod 11 is connected to one side of the turntable 8. By setting the sleeve plate 2, when the turntable 8 rotates, the surface protrusion 10 contacts the contact plate 14, and the contact plate 14 drives the connecting plate 4 to slide in the sleeve plate 2, so that the sleeve plate 2 plays a certain guiding role for the connecting plate 4, avoiding the phenomenon of dislocation of the connecting plate 4 when moving;
[0022] A guide rod 15 is connected inside the connecting plate 4, and the card plate 12 is rotatably connected to the outside of the guide rod 15. A coil spring 16 is connected to the outer sleeve of the guide rod 15. The card plate 12 is connected to the guide rod 15 through the coil spring 16. By setting the guide rod 15 and the coil spring 16, when the card plate 12 moves on the side of the sleeve plate 2, the card plate 12 will rotate around the guide rod 15, and the card plate 12 will drive the coil spring 16 to deform, so that the guide rod 15 and the coil spring 16 play a certain limiting role on the card plate 12, thereby avoiding the phenomenon of the card plate 12 getting stuck when rotating.
[0023] The working principle of the utility model is:
[0024] When the relay protection device needs to be placed in the working area, the shell 1 can be placed in the appropriate position first, and then the motor 9 can be used to drive the rotating rod 7 to rotate. When the turntable 8 rotates, the protrusion 10 on the surface will contact the contact plate 14, and the contact plate 14 will drive the connecting plate 4 to slide in the sleeve plate 2, and the connecting plate 4 will drive the table plate 3 to move in the shell 1, and the clamping plate 12 will also move on the surface of the sleeve plate 2. When the connecting plate 4 moves to the appropriate position, the clamping plate 12 will overlap in the clamping groove 17 through the action of the coil spring 16, and the connecting plate 4 will drive the table plate 3 to move to a certain position, and then the device body 6 is placed in the groove 5. When the turntable 8 rotates, the fixed rod 11 on the surface contacts the L-shaped plate 13, the clamping plate 12 will be separated from the clamping groove 17, and then the connecting plate 4 will drive the table plate 3 to recover.
