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 isolating switch. Background Art

[0002] Outdoor high-voltage AC single-phase disconnector is an important device used to isolate power supply and change the operation mode in the power system. It plays a key role in the field of high-voltage power transmission and distribution. It is mainly used to disconnect or close high-voltage circuits in the absence of current to ensure the safety of maintenance personnel during equipment maintenance. It can also be used to switch circuits to meet the needs of different operating conditions. The outdoor high-voltage AC single-phase disconnector includes the following components: a contact system, a conductive rod, a support insulator, an insulating operating rod and a base, among which the conductive part and the insulating part are exposed; However, at present, in order to prevent the entry of sand and dust and affect the use of outdoor high-voltage AC single-phase disconnectors in windy and sandy environments, common methods include sealing design, protective coating, dust cover or protective net. Among them, the sealing design and protective coating methods will cause oxidation during long-term use, resulting in sand and dust adhering to the surface between the conductors connected to the composite insulators such as conductive poles or terminal blocks and the grounding body (or grounding components such as pole towers), forming a dirt layer. In rainy weather, the dirt layer will absorb moisture to form a conductive channel, causing the insulation resistance of the insulator to decrease and the leakage current to increase, thereby causing the insulator to have a flashover risk and accelerate the aging of the insulator, causing the switch to lose 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

[0020] Among them, an outgoing copper bar 11 is fixedly connected to the top of the left composite insulator 1, and an incoming 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 incoming copper bar 12. The outgoing copper bar 11 is movably connected to a moving blade 14 through an insertion shaft, and the moving blade 14 is in movably contact with the contact 13. The insertion shaft is movably sleeved with a first spring 15, and the first spring 15 is in fixed contact with the moving blade 14.

The isolation mechanism 2 includes an insulating pull rod 21, which is hingedly connected to the bottom of the moving blade 14. The inner walls on both sides of the base 16 are symmetrically provided with two slide grooves 22. The two slide grooves 22 are respectively slidably connected with waist-shaped sliders 23. 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. The first gear 25 is fixedly sleeved on the inserted rod on the transmission frame 24. The inner walls on both sides of the base 16 are movably connected with drive modules 26.

[0022] When in use, the first gear 25 meshes with the sector gear 261 for transmission, applying a thrust to the insulating pull rod 21, causing the insulating pull rod 21 to push the movable blade 14, so that the movable 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 movable blade 14 to separate from the contact 13.

[0023] The present invention sets an isolation mechanism 2, and when the driving module 26 rotates clockwise or counterclockwise, a thrust or torque force is applied to the first gear 25, causing the movable blade 14 to translate or rotate axially, thereby realizing translational or rotational gate opening, and scraping both sides of the movable blade 14 through the protective component, and through the vibration unit 4, not only scraping can be achieved, but also dust can be vibrated to remove the dead corners on the scraping component. When passing through the cleaning unit 5, the insulating pull rod 21 is compressed, causing the jet component to expand and perform gas dust removal on the surface of the surrounding components, so as to keep the switch clean and avoid dust accumulation. In a humid environment, a circuit channel is formed, which affects the opening and power-off effect of the switch. Example

[0024] like Figure 3 , Figure 5 and Fig.11As shown, in an embodiment of the present invention, the protective assembly 3 includes two protective shells 31, and the two protective shells 31 are respectively fixedly arranged on the top of the composite insulator 1, and two supporting plates 32 are commonly fixedly connected to the opposite sides of the two protective shells 31, and the movable blade 14 is arranged between the two supporting plates 32, and air bags 33 are arranged inside the two supporting plates 32, and a plurality of scrapers 34 are arranged in a linear array on the opposite sides of the two air bags 33, and the scrapers 34 are in active contact with the movable blade 14.

When in use, the airbag 33 expands, the scraper 34 contacts the moving blade 14, the airbag 33 is compressed, the scraper 34 separates from the moving blade 14, and the protective shell 31 is made of non-conductive material. Example

[0026] like Figure 5-6 and Fig.11 As shown, in an embodiment of the present invention, the vibration elimination unit 4 includes a rubber plate 41, which is fixedly connected to the inner wall of one side of the airbag 33, and a plurality of knocking plates 42 are arranged in a linear array on the inner wall of the other side of the airbag 33, and adjacent knocking plates 42 are hingedly connected, and a plurality of knocking plates 42 are stacked and distributed, and two support plates 43 are movably arranged inside the airbag 33, and an upper support plate 43 is provided with an air inlet hole 431, and a movable cylinder 44 is rotatably connected between the two support plates 43, and a transmission blade 45 is fixedly connected to the inside of the movable cylinder 44 in an annular array, and a plurality of knocking blocks 46 are hingedly connected to the side surface of the movable cylinder 44 in an annular array, and the knocking blocks 46 are respectively in contact with the rubber plate 41 and the knocking plate 42.

[0027] During use, when filling gas, several knocking blocks 46 rotate axially and contact through the rubber plate 41, increasing the friction force, causing them to move in the airbag 33, and when passing through the knocking plate 42, a vibration force is applied to it, thereby cleaning the dirt in the dead corners of the scraper 34, and when extracting gas, several knocking blocks 46 rotate axially in the opposite direction, move in the airbag 33 through the rubber plate 41, and clean the dirt in the dead corners of the scraper 34.

[0028] The present invention fills the movable cylinder 44 with gas through the air inlet hole 431. The gas passes through the transmission blade 45, so that the plurality of knocking blocks 46 move axially. When the knocking blocks 46 contact the rubber plate 41, they can drive them to move in the airbag 33. When they contact the knocking plate 42, vibration force is applied to the scraper 34 to remove dust in the dead corners of the scraper 34. In addition, the knocking plates 42 are arranged in a stacked manner, so that the moving parts can move in an orderly manner in the airbag 33, 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. Example

[0029] like Figure 8-10As shown, as another embodiment of the present invention, the cleaning unit 5 is arranged inside the insulating pull rod 21, and the cleaning unit 5 includes a through groove 51, which is opened on the side surface of the lower insulating pull rod 21, and the interior of the through groove 51 is a symmetrical structure with two movable blocks 52 movably connected by a latch, and the inner walls on both sides of the through groove 51 are symmetrically structured with two notches 511, and the inner wall on one side of each notch 511 is fixedly connected to a micro spring 53, and the micro spring 53 is in movably contact with the latch, 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 to the inside of the lower insulating pull rod 21, and two support plates 55 are hingedly connected to the bottom of the two sides of the support piece 54, and the two support plates 55 are both hingedly connected to the movable block 52.

[0030] Specifically, a semicircular inlet hole 521 is respectively opened on the opposite side of the two movable blocks 52 , and the two semicircular inlet holes 521 are combined to form a circular hole. An air outlet hole 522 is opened at the bottom of the two movable blocks 52 , and the air outlet hole 522 is connected to the semicircular inlet hole 521 .

[0031] When in use, when the two insulating rods 21 are compressed, the two movable blocks 52 are expanded through the support pieces 54 and the support plates 55, and the two air outlet holes 522 are connected with the internal flow space of the insulating rods 21 below, and the two air outlet holes 522 are circular, thereby cleaning the parts on the base 16.

[0032] The present invention sets a movable block 52. When the upper and lower insulating pull rods 21 are squeezed, the support sheet 54 cooperates with the support plate 55 to spread the two movable blocks 52 evenly, and the two semicircular inlet holes 521 are combined into a circular hole, so that gas can be ejected from the air outlet 522 to remove dust from the surrounding parts. When the upper and lower insulating pull rods 21 are stretched, the two movable blocks 52 gather together, so that the two movable blocks 52 and the movable blocks 52 are cylindrical, and the air outlet 522 is closed by fitting with the insulating pull rod 21 to avoid being affected by wind and sand, causing the air outlet 522 to be blocked and affecting its normal use.

[0033] Working principle: This embodiment provides an outdoor high-voltage AC single-phase isolating switch. When the outdoor high-voltage AC single-phase isolating switch is opened in a translational manner, the handle 27 is turned to rotate the driving module 26 clockwise, and the first gear 25 contacts the surface of the cam 262, causing the cam 262 to apply a thrust to the transmission frame 24, and a force to tilt the insulating pull rod 21 to the left, thereby causing the movable blade 14 to move to the left, and slide on the surface of the plug through the first waist hole 141, thereby separating the movable blade 14 from the contact 13, and realizing the translational opening, such as Fig.14As shown; when the rotary gate is opened, the handle 27 is used to rotate the drive module 26 counterclockwise, causing the sector gear 261 to mesh with the first gear 25 for transmission, applying an axial rotational force to the end of the insulating rod 21, so that the insulating rod 21 moves upward in an arc, causing the movable blade 14 to rotate axially and disconnect from the contact 13, thereby achieving a rotary gate opening effect, as shown in FIG. Fig.13 As shown; During the gate opening process, gas is applied through the air inlet 431 through the external pneumatic system. When the gas passes through the movable cylinder 44, it rotates through the transmission blade 45, and a plurality of knocking blocks 46 rotate with the movable cylinder 44 as the axis. The knocking blocks 46 are in active contact with the rubber plate 41 to increase the friction force, causing the support plate 43 to move inside the airbag 33, and the knocking blocks 46 generate a vibration force on the knocking plate 42, so that the dust in the dead corner of the scraper 34 is vibrated and removed. In this process, flexible vibration is applied to the airbag 33 to prevent To prevent the scraper 34 from vibrating too much and causing damage to the movable blade 14, after use, the external pneumatic system is used to cause the movable cylinder 44 to rotate in the opposite direction, and the support plate 43 moves in the opposite direction in the air bag 33, and the knocking plate 42 is stacked to provide space for the support plate 43 to move in the opposite direction, so as to avoid the space in the air bag 33 being restricted during use, resulting in the moving parts being unable to move normally, and applying vibration force to the scraper 34 when moving in the opposite direction, thereby removing the dust accumulated on its surface; When the gate is rotated to open, the lower insulating rod 21 applies a thrust to the upper insulating rod 21, and the bottom of the upper insulating rod 21 slides a short distance inside the lower insulating rod 21, so that the support piece 54 applies a force to the support plate 55, causing the support plate 55 to rotate axially, and the two movable blocks 52 are rotated through the latch, and the two movable blocks 52 are adjusted by the micro spring 53, so that the two movable blocks 52 move in a flat state, so that the two semicircular inlet holes 521 form a circular hole and are connected to the inside of the insulating rod 21, and then through the external pneumatic system, the gas passes through the lower insulating rod 21 and is ejected from the air outlet 522, so as to remove dust from the components above the base 16, thereby avoiding dust accumulation on the components above the base 16, and forming a circuit channel in a humid environment, affecting the breaking effect of the composite insulator 1.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
