[0002] The most important function of high-voltage isolating switches in power grids is to establish a reliable insulation gap, separating the equipment or lines that need to be repaired from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment. Therefore, whether the opening and closing of the high-voltage isolating switch is in place plays a decisive role in whether the insulation gap it establishes is reliable.

[0003] When the existing angular displacement detection devices are in use, most of them use pointers to display the angular displacement, so that the angular displacement detection devices do not have the function of automatically alarming when the displacement angle does not meet the standard. Workers are required to judge whether the opening and closing of the switch are qualified through observation, which makes the detection results prone to deviations, thereby reducing the practicality of the angular displacement detection device.

[0004] To this end, we propose a high-voltage disconnector angular displacement detection device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A high-voltage disconnector angular displacement detection device includes a connecting plate 1, a mounting plate 12 is provided on the back of the connecting plate 1, two sets of fixing bolts 13 are connected to the internal threads of the mounting plate 12, and one end of each fixing bolt 13 away from the connecting plate 1 passes through the mounting plate 12 and extends to the back of the mounting plate 12. The installation of the mounting plate 12 and the fixing bolts 13 can fix the device inside a cabinet where the high-voltage disconnector is placed, thereby avoiding the movement of the device as much as possible, thereby ensuring the stability of the device.

[0023] A controller 2, a buzzer 3 and an angular displacement sensor 4 are fixedly installed on the front of the connecting plate 1. The controller 2 is a PLC controller 2, the model of the buzzer 3 is PL-12C, and the model of the angular displacement sensor 4 is R30A. Two groups of cylinders 14 are fixedly installed on the front of the mounting plate 12. The telescopic ends of each cylinder 14 are fixedly connected to the back of the connecting plate 1. The power provided by the cylinder 14 is used to drive the connecting plate 1 to move, thereby adjusting the distance between the connecting plate 1 and the mounting plate 12, thereby facilitating the angular displacement detection of high-voltage disconnectors with different lengths from the cabinet.

[0024] A connecting gear 5 is fixedly installed on the detection end of the angular displacement sensor 4, and a rotating gear 6 is rotatably connected to the front side of the connecting plate 1. The outer surface of the rotating gear 6 is meshed with the outer surface of the connecting gear 5. A connecting bearing 20 is fixedly installed on the back side of the rotating gear 6. The back side of the inner ring of the connecting bearing 20 is fixedly connected to the front side of the connecting plate 1. The installation of the connecting bearing 20 stabilizes the rotating gear 6, thereby minimizing the shaking of the rotating gear 6 during rotation, thereby ensuring the stability of the rotating gear 6.

[0025] A connecting pipe 7 is fixedly installed on the front of the rotating gear 6, a rubber sleeve 8 is fixedly installed on the inner wall of the connecting pipe 7, a wireless transmission module 15 is fixedly installed on the front of the connecting plate 1, the wireless transmission module 15 is electrically connected to the controller 2 through a wire, the model of the wireless transmission module 15 is DTD435M, and the use of the wireless transmission module 15 allows workers to remotely send instructions to the controller 2 through the terminal, thereby eliminating the need for workers to go to the site to set the alarm angle, thereby increasing the practicality of the device.

[0026] Two hydraulic rods 9 are fixedly installed on the inner wall of the connecting pipe 7, a protective shell 16 is fixedly installed on the front of the connecting plate 1, and a protective glass 17 is fixedly installed on the inner wall of the protective shell 16. The installation of the protective shell 16 plays a role in protecting the electronic components of the device, thereby avoiding the electronic components from external collisions as much as possible. The installation of the protective glass 17 makes it convenient for workers to observe the operating status of the internal electronic components.

[0027] Two expansion pieces 10 are arranged inside the rubber sleeve 8, and the ends of the two hydraulic rods 9 that are away from each other are fixedly connected to the side surfaces of the two expansion pieces 10 that are close to each other. Two sets of heat dissipation ports 18 are opened on the upper surface of the protective shell 16, and a dustproof net 19 is fixedly installed on the upper surface of the protective shell 16. The opening of the heat dissipation ports 18 increases the air flow inside the protective shell 16, thereby achieving a certain heat dissipation effect. The installation of the dustproof net 19 can prevent dust from entering the interior of the protective shell 16 as much as possible, thereby reducing the influence of dust on the operating state of electronic components.

[0028] Two sets of connecting springs 11 are fixedly installed on the side where the two expansion pieces 10 are close to each other. A telescopic rod 21 is sleeved inside each connecting spring 11. The end of each telescopic rod 21 that is away from each other is fixedly connected to the side where the two expansion pieces 10 are close to each other. The installation of the telescopic rod 21 plays a role in limiting the movement trajectory of the expansion pieces 10, thereby minimizing the phenomenon of deviation of the expansion pieces 10 during relative movement, thereby ensuring the stability of the movement of the expansion pieces 10.

[0029] The working principle of the utility model is as follows: when in use, the worker first sets the connecting pipe 7 on the outer surface of the knife switch rotating shaft, and uses the power provided by the hydraulic rod 9 to drive the two expansion pieces 10 to move toward the side close to each other, so that the two expansion pieces 10 drive the rubber sleeve 8 to extend toward the inside of the connecting pipe 7, and then fix the connecting pipe 7 on the knife switch rotating shaft. After that, the worker opens the cylinder 14, and uses the power provided by the cylinder 14 to drive the mounting plate 12 to move toward the side away from the connecting plate 1, so that the mounting plate 12 contacts the cabinet body with the high-voltage disconnector, and uses the fixing bolts 13 to fix the mounting plate 12 to the cabinet body, thereby completing the diagonal displacement detection device. During the installation process, the worker sets the angular displacement threshold of the opening and closing of the gate through the terminal, so that the terminal sends the signal to the controller 2 through the wireless transmission module 15. When the worker is opening and closing the gate, the knife rotating shaft will cooperate with the connecting pipe 7 to drive the rotating gear 6 to rotate, so that the rotating gear 6 drives the connecting gear 5 to rotate, and then the angular displacement of the opening and closing of the gate is transmitted to the controller 2 through the angular displacement sensor 4, so that the controller 2 compares the actual angular displacement data with the set threshold. When the data comparison does not meet the standard, the controller 2 controls the buzzer 3 to sound an alarm, thereby reminding the on-site workers that the opening and closing of the gate does not meet the standard, so as to facilitate the workers to respond in time.
