Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage power transmission switches, and more specifically, to an outdoor high-voltage AC single-phase disconnector. Background Art

[0002] An outdoor high-voltage AC single-phase disconnector is an important device in the power system for isolating power sources and changing operating modes, playing a key role in high-voltage power transmission and distribution fields; it is mainly used to disconnect or close high-voltage circuits under no-load conditions to ensure the safety of maintenance personnel during equipment maintenance, and can also be used to switch circuits to meet the requirements of different operating conditions;

[0003] The outdoor high-voltage AC single-phase disconnector consists of the following components: a contact system, a conductive rod, a support insulator, an insulating operating rod, and a base, etc. Among them, components such as the conductive part and the insulating part are exposed.

[0004] However, currently, when used in a sandy environment, in order to prevent sand and dust from entering and affecting the use of the outdoor high-voltage AC single-phase disconnector, common methods include sealing design, protective coatings, dust covers, or protective nets, etc. Among them, in the case of long-term use of the sealing design and protective coating methods, due to oxidation, sand and dust will adhere to the surface between the conductive rod or the terminal block and the conductors and grounding bodies (or grounding components such as towers) connected to the composite insulator, forming a fouling layer. In rainy weather, the fouling layer will absorb moisture and form a conductive channel, resulting in a decrease in the insulation resistance of the insulator and an increase in the leakage current, thereby causing a risk of flashover of the insulator and accelerating the aging of the insulator, resulting in the switch losing its insulation ability and causing equipment damage; in view of this, we propose an outdoor high-voltage AC single-phase disconnector. Summary of the Invention

[0005] The purpose of the present invention is to provide an outdoor high-voltage AC single-phase disconnector to solve the technical problem that dust accumulates on the surface of the switch in a humid environment, forming a circuit channel and affecting the opening and power-off technology.

[0006] To solve the above technical problems, the present invention provides the following technical solution: an outdoor high-voltage AC single-phase disconnector, including two composite insulators, an isolation mechanism, a protection component, a vibration removal unit, and a cleaning unit. A moving blade is movably arranged at the top of the left composite insulator;

[0007] The isolation mechanism includes an insulating pull rod, which is hinged at the bottom of the moving blade. The insulating pull rod is composed of an upper insulating pull rod inserted into a lower insulating pull rod, and the lower insulating pull rod is in a hollow shape.

Semi-circular inlet holes are respectively formed on one side of the two movable blocks facing each other. The two semi-circular inlet holes are combined into a circular hole. Air outlet holes are formed at the bottoms of the two movable blocks, and the air outlet holes are communicated with the semi-circular inlet holes;

[0010] When gas is filled or extracted, it passes through the transmission blades and rotates clockwise and counterclockwise. The knocking blocks rotate axially to apply a flexible vibration to the scraper, so as to remove the dust at the dead corners of the scraper;

[0011] When the upper and lower insulating pull rods are compressed, the movable blocks are arranged flatly. The two semi-circular inlet holes form a circular hole and are communicated with the lower insulating pull rod. Gas blows out from the air outlet holes to remove the dust on the surfaces of other components. By setting the isolation mechanism in the present invention, when the driving module rotates clockwise and counterclockwise, a thrust or torque acting force is applied to the first gear, causing the moving blade to translate or rotate axially, thereby realizing a translational opening or a rotational opening of the gate. And through the protection component, the two sides of the moving blade are scraped. And through the vibration removal unit, not only scraping can be realized, but also the dust at the dead corners of the scraping components can be removed by vibration. When passing through the cleaning unit, the insulating pull rod is compressed, causing the jet component to unfold and perform gas dust removal on the surfaces of the surrounding components, so as to keep the switch clean, avoid sand accumulation, and form a circuit channel in a humid environment, affecting the gate opening and power-off effect of the switch.

[0012] Preferably, an outlet copper row is fixedly connected to the top of the left composite insulator, an inlet copper row is fixedly connected to the top of the right composite insulator, a contact is arranged on the top of the inlet copper row. The moving blade is movably connected to one side of the outlet copper row through a plug shaft, and the moving blade is in movable contact with the contact. A first waist-shaped hole is formed in the moving blade close to the left composite insulator. The plug shaft is movably sleeved with a first spring, and the first spring is fixedly in contact with the moving blade. The bottoms of the two composite insulators are fixedly provided with bases.

[0013] Preferably, the isolation mechanism further includes two chutes. The two chutes are symmetrically formed on the inner walls of both sides of the base. Waist-shaped sliders are respectively slidably connected inside the two chutes. A transmission frame is rotatably connected between the two waist-shaped sliders. The transmission frame is hinged to the bottom of the insulating pull rod. A first gear is fixedly sleeved on the plug rod of the transmission frame.

[0014] Preferably, drive modules are movably connected to the inner walls on both sides of the base. One end of each drive module is fixedly connected to a handle. First telescopic rods are fixedly connected to the inner walls on one side of each of the two chutes. A second spring is movably sleeved on the side surface of each first telescopic rod.

[0015] Preferably, the drive module is composed of a sector gear and a cam. The sector gear is meshed with the first gear, and the sector gear is also in movable contact with the cam.

[0016] Preferably, the protection assembly further includes two protective shells. The two protective shells are respectively fixedly arranged on the top of the composite insulator. Two support plates are fixedly connected to the opposite sides of the two protective shells. The moving blade is arranged between the two support plates, and the airbag is arranged inside the support plates.

[0017] Preferably, the vibration removal unit further includes a rubber plate. The rubber plate is fixedly connected to the inner wall on one side of the airbag. A plurality of knocking plates are linearly arranged on the inner wall on the other side of the airbag. Adjacent knocking plates are hinged, and the plurality of knocking plates are arranged in an overlapping distribution.

[0018] Preferably, two support discs are movably arranged inside the airbag. An air inlet hole is provided in the upper support disc. The knocking blocks are respectively in movable contact with the rubber plate and the knocking plates.

[0019] Preferably, the cleaning unit further includes a through groove. The through groove is opened on the side surface of the lower insulating pull rod. Two notches are symmetrically opened on the inner walls on both sides of the through groove.

[0020] Preferably, a micro spring is fixedly connected to the inner wall on one side of each notch. The micro spring is in movable contact with the pins on both sides of the movable block. A support piece is fixedly connected to the bottom of the upper insulating pull rod. The support piece is movably connected inside the lower insulating pull rod. Two support plates are hinged to the bottom on both sides of the support piece. Both support plates are hinged to the movable block.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By setting the isolation mechanism, when the drive module rotates clockwise and counterclockwise, a thrust or torque acting force is applied to the first gear, causing the moving blade to translate or rotate axially, thereby realizing translational opening or rotational opening of the gate. And through the protection assembly, the two sides of the moving blade are scraped. Through the vibration removal unit, not only scraping can be realized, but also dust vibration removal treatment can be carried out on the dead corners of the scraping parts. When passing through the cleaning unit, the insulating pull rod is compressed, causing the jet component to unfold to perform gas dust removal treatment on the surfaces of surrounding components, so as to keep the switch clean, avoid sand accumulation, and form a circuit channel in a humid environment, affecting the opening and power-off effect of the switch.

[0023] 2. The present invention fills the movable cylinder with gas through the air inlet hole. The gas passes through the transmission blade to make several knocking blocks move axially. When the knocking blocks contact the rubber plate, they can drive it to move in the airbag. When they contact the knocking plate, they apply vibration force to the scraper to remove dust in the dead corners of the scraper. In addition, by arranging several knocking plates in a stacked manner, the moving parts can move in the airbag in an orderly manner, avoiding the situation in which the moving space is affected by gas extraction during use, causing the moving parts to be unable to move normally.

[0024] 3. The present invention sets movable blocks. When the upper and lower insulating rods are squeezed, the two movable blocks are spread out and separated by the support sheet and the support plate, and the two semicircular inlet holes are combined into a circular hole, so that the gas can be ejected from the air outlet, and the surrounding parts are dust-removed. When the upper and lower insulating rods are stretched, the two movable blocks gather together, so that the two movable blocks and the movable blocks are cylindrical, and the air outlet is closed by fitting with the insulating rod to avoid being affected by wind and sand, which causes the air outlet to be blocked and affects its normal use.

[0040] As Figure 1-2 , Figure 4 , Figures 7-10 and Figures 12-14 shown, an outdoor high-voltage AC single-phase disconnector involved in the present invention includes two composite insulators 1, an isolation mechanism 2, a protection component 3, a vibration removal unit 4 and a cleaning unit 5; the isolation mechanism 2 is arranged between the two composite insulators 1, the protection component 3 is arranged on the tops of the two composite insulators 1, the vibration removal unit 4 is arranged inside the protection component 3, and the cleaning unit 5 is arranged inside the isolation mechanism 2.

[0041] Among them, an outlet copper bar 11 is fixedly connected to the top of the left composite insulator 1, an inlet copper bar 12 is fixedly connected to the top of the right composite insulator 1, a contact 13 is arranged on the top of the inlet copper bar 12, the outlet copper bar 11 is movably connected to a moving blade 14 through a plug shaft, and the moving blade 14 is in movable contact with the contact 13. The plug shaft is movably sleeved with a first spring 15, and the first spring 15 is fixedly in contact with the moving blade 14. The bottoms of the two composite insulators 1 are fixedly arranged with a base 16, and a first waist-shaped hole 141 is opened in the moving blade 14 close to the left composite insulator 1;

[0042] The isolation mechanism 2 includes an insulating pull rod 21, and the insulating pull rod 21 is hinged to the bottom of the moving blade 14. Two sliding grooves 22 are symmetrically formed on the inner walls of both sides of the base 16. Waist-shaped sliders 23 are respectively slidably connected inside the two sliding grooves 22. A transmission frame 24 is rotatably connected between the two waist-shaped sliders 23. The transmission frame 24 is hinged to the bottom of the insulating pull rod 21. A first gear 25 is fixedly sleeved on the insertion rod of the transmission frame 24. A driving module 26 is movably connected to the inner walls of both sides of the base 16. One end of the driving module 26 is fixedly connected with a handle 27. First telescopic rods 28 are respectively fixedly connected to the inner walls of one side of the two sliding grooves 22. A second spring 29 is movably sleeved on the side surface of each first telescopic rod 28.

[0043] Specifically, the insulating pull rod 21 is formed by inserting the upper insulating pull rod 21 into the lower insulating pull rod 21, and has a small range of stretching effect. The lower insulating pull rod 21 is in a hollow shape. The driving module 26 is composed of a sector gear 261 and a cam 262. The sector gear 261 is meshed and connected with the first gear 25, and the sector gear 261 is also in movable contact with the cam 262.

[0044] During use, the first gear 25 and the sector gear 261 are meshed and transmitted to apply a thrust to the insulating pull rod 21, causing the insulating pull rod 21 to push the moving blade 14, so that the moving blade 14 is separated from the contact 13; when the sector gear 261 contacts the inner groove on the cam 262, a thrust is applied to the transmission frame 24, and the transmission frame 24 translates, causing the moving blade 14 to be separated from the contact 13.

[0045] By setting the isolation mechanism 2 in the present invention, when the driving module 26 rotates clockwise and counterclockwise, a thrust or torque acting force is applied to the first gear 25, causing the moving blade 14 to translate or rotate axially, thereby realizing translational opening or rotational opening of the switch. And through the protection component, the two sides of the moving blade 14 are scraped, and through the vibration removal unit 4, not only scraping can be realized, but also the dust at the dead corners of the scraping components can be removed by vibration. When passing through the cleaning unit 5, the insulating pull rod 21 is compressed, causing the jet component to unfold and perform gas dust removal treatment on the surfaces of the surrounding components, so as to keep the switch clean, avoid sand accumulation, and form a circuit channel in a humid environment, affecting the switch opening and power-off effect. Embodiment

[0046] Such as Figure 3 、 Figure 5 And Figure 11As shown, in the embodiment of the present invention, the protection component 3 includes two protective shells 31, which are respectively fixedly arranged on the top of the composite insulator 1. On the opposite sides of the two protective shells 31, two support plates 32 are fixedly connected together. The moving blade 14 is arranged between the two support plates 32. Air bags 33 are arranged inside the two support plates 32. A number of scraping plates 34 are linearly arranged on the opposite sides of the two air bags 33, and the scraping plates 34 are in movable contact with the moving blade 14.

[0047] It should be noted that the scraping plates 34 are all made of rubber material. During use, when the air bag 33 expands, the scraping plates 34 come into contact with the moving blade 14, and when the air bag 33 compresses, the scraping plates 34 are separated from the moving blade 14. Also, the protective shells 31 are all made of non-conductive materials. Embodiment

[0048] As Figures 5-6 and Figure 11 As shown, in the embodiment of the present invention, the vibration removal unit 4 includes a rubber plate 41, which is fixedly connected to the inner wall of one side of the air bag 33. A number of knocking plates 42 are linearly arranged on the inner wall of the other side of the air bag 33, and adjacent knocking plates 42 are hinged. Also, a number of knocking plates 42 are arranged in a stacked distribution. Two support disks 43 are movably arranged inside the air bag 33, and an air inlet hole 431 is opened in the upper support disk 43. An activity cylinder 44 is rotatably connected between the two support disks 43. A number of transmission paddle blades 45 are fixedly connected in a circular array inside the activity cylinder 44. A number of knocking blocks 46 are hinged on the side surface of the activity cylinder 44 in a circular array, and the knocking blocks 46 are in movable contact with the rubber plate 41 and the knocking plates 42 respectively.

[0049] During use, when filling with gas, when a number of knocking blocks 46 make axial rotation, through contact with the rubber plate 41, the friction force is increased, causing it to move inside the air bag 33. And when passing through the knocking plates 42, a vibration force is applied to them, thereby cleaning the dirt in the dead corners on the scraping plates 34. Also, when extracting gas, a number of knocking blocks 46 make axial reverse rotation, move inside the air bag 33 through the rubber plate 41, and clean the dirt in the dead corners on the scraping plates 34.

[0050] In the present invention, gas is filled into the activity cylinder 44 through the air inlet hole 431. The gas passes through the transmission paddle blades 45, causing a number of knocking blocks 46 to move axially. When the knocking blocks 46 come into contact with the rubber plate 41, it can drive it to move inside the air bag 33. When coming into contact with the knocking plates 42, a vibration force is applied to the scraping plates 34 to solve the dust in the dead corners on the scraping plates 34. Also, due to the stacked arrangement of a number of knocking plates 42, the moving components can move orderly inside the air bag 33, avoiding the influence of the moving space due to gas extraction during use, resulting in the inability of the moving components to move normally. Embodiment

[0051] As Figures 8-10As shown, as another embodiment of the present invention, the cleaning unit 5 is arranged inside the insulating pull rod 21. The cleaning unit 5 includes a through groove 51. The through groove 51 is opened on the side surface of the lower insulating pull rod 21. Two movable blocks 52 are movably connected inside the through groove 51 in a symmetrical structure through pins. Two notch openings 511 are symmetrically opened on both inner walls of the through groove 51. A micro spring 53 is fixedly connected to the inner wall of one side of each notch opening 511, and the micro spring 53 is in movable contact with the pin. A support piece 54 is fixedly connected to the bottom of the upper insulating pull rod 21, and the support piece 54 is movably connected inside the lower insulating pull rod 21. Two support plates 55 are hingedly connected to the bottom of both sides of the support piece 54, and both support plates 55 are hingedly connected to the movable blocks 52.

[0052] Specifically, semi-circular inlet holes 521 are respectively opened on the opposite sides of the two movable blocks 52. The two semi-circular inlet holes 521 are combined into a circular hole. Air outlet holes 522 are opened at the bottoms of the two movable blocks 52, and the air outlet holes 522 are communicated with the semi-circular inlet holes 521.

[0053] During use, when the two insulating pull rods 21 are compressed, through the support piece 54 and the support plates 55, the two movable blocks 52 are caused to unfold. The two air outlet holes 522 are communicated with the internal flow space of the lower insulating pull rod 21, and the two air outlet holes 522 are circular in shape, thereby cleaning the components on the base 16.

[0054] In the present invention, by arranging the movable blocks 52, when the upper and lower insulating pull rods 21 are squeezed, through the cooperation of the support piece 54 and the support plates 55, the two movable blocks 52 are distributed flatly, and the two semi-circular inlet holes 521 are combined into a circular hole, so that gas can be ejected from the air outlet holes 522 to remove dust from the surrounding components. When the upper and lower insulating pull rods 21 are stretched, the two movable blocks 52 gather, causing the two movable blocks 52 to be in a cylindrical shape, and the air outlet holes 522 are closed by fitting with the insulating pull rod 21, avoiding being affected by wind and sand, resulting in the blockage of the air outlet holes 522 and affecting its normal use.

[0055] Working principle: This embodiment provides an outdoor high-voltage AC single-phase disconnector. When the outdoor high-voltage AC single-phase disconnector is opened in a translational manner, by rotating the handle 27, the driving module 26 rotates clockwise. The first gear 25 applies a thrust to the transmission frame 24 by contacting the surface of the cam 262, applying a force to the insulating pull rod 21 obliquely to the left, thereby causing the moving blade 14 to move to the left, and sliding through the first waist-shaped hole 141 on the insertion rod surface, thereby separating the moving blade 14 from the contact 13 to achieve translational opening, as Figure 14As shown in the figure; during rotary opening of the switch, by turning the handle 27, the driving module 26 rotates counterclockwise, causing the sector gear 261 to mesh with the first gear 25 for transmission, applying an axially rotating force to the end of the insulating pull rod 21, causing the insulating pull rod 21 to move upward in an arc, and causing the moving blade 14 to rotate axially to disconnect from the contact 13, thereby achieving the effect of rotary opening of the switch, as Figure 13 shown;

[0056] During the process of opening the switch, through an external pneumatic system, gas is applied through the air inlet hole 431. When the gas passes through the movable cylinder 44, it rotates through the transmission paddle 45. Several striking blocks 46 rotate around the movable cylinder 44. The striking blocks 46 are in movable contact with the rubber plate 41 to increase the friction force, causing the support plate 43 to move inside the airbag 33, and generating a vibration force on the striking plate 42 through the striking blocks 46 to remove the dust at the dead corners on the scraping plate 34. During this process, a flexible vibration is applied to the airbag 33 to prevent the scraping plate 34 from vibrating too much and damaging the moving blade 14 and other conditions. After use, through the external pneumatic system, the movable cylinder 44 rotates in the reverse direction, the support plate 43 moves in the reverse direction inside the airbag 33, and the striking plates 42 are arranged in a stacked manner to provide space for the support plate 43 to move in the reverse direction, avoiding the space inside the airbag 33 being restricted during use, resulting in the inability of the moving components to move normally, and applying a vibration force to the scraping plate 34 during the reverse movement to remove the dust accumulated on its surface;

[0057] During rotary opening of the switch, the lower insulating pull rod 21 applies a thrust to the upper insulating pull rod 21. The bottom of the upper insulating pull rod 21 slides a short distance inside the lower insulating pull rod 21, causing the support piece 54 to apply a force to the support plate 55, causing the support plate 55 to rotate axially, rotating the two movable blocks 52 through a pin, and adjusting the two movable blocks 52 through the micro spring 53, causing the two movable blocks 52 to move in a flat state, making the two semi-circular inlet holes 521 form a circular hole and communicate with the inside of the insulating pull rod 21. Then, through the external pneumatic system, gas is ejected from the air outlet hole 522 through the lower insulating pull rod 21 to perform a dust removal effect on the components above the base 16, avoiding dust accumulation on the components above the base 16, and in a humid environment, forming a circuit channel, affecting the switching off current breaking effect of the composite insulator 1.

[0058] The embodiments disclosed in the present invention are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes, but as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
