Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to an electric power safety switch. Background Art

[0002] A power safety switch is a device used to protect circuits and electrical equipment. Its main function is to automatically or manually cut off the power supply when an electrical fault occurs to prevent electrical fires and equipment damage and ensure personal and property safety. Power safety switches are widely classified, among which high-voltage power isolation switches are used in substations, distribution networks, high-voltage lines and other occasions that require high-voltage power access or isolation.

[0003] High-voltage power isolating switches are mainly used to isolate power supplies to ensure the safety of circuits during maintenance or overhaul. Isolating switches are usually used in conjunction with protective equipment such as circuit breakers and fuses. They consist of a base, support insulators, conductive parts and operating mechanisms. When circuit isolation is required, first disconnect the circuit breaker or fuse, and then operate the isolating switch, which is generally equipped with a manual or electric operating mechanism. When the high-voltage power isolating switch disconnects the circuit, a brief arc will appear at its disconnection point when it is separated. Although the prior art has a variety of ways to extinguish the arc, if the high-voltage power isolating switch and power equipment are installed in outdoor areas, the cost of using arc extinguishing chambers and vacuum arc extinguishing methods is relatively high, and some areas have a lot of rain all year round. If the arc is often in contact with rainwater during isolation and disconnection, it will cause great safety hazards and seriously affect the overall stability of the power equipment.

[0035] See also Figure 1-9 .

[0036] The present invention provides a technical solution for an electric safety switch: an electric safety switch comprises a combined switch seat 1, comprising symmetrically arranged insulating pillars 101 and conductive strips 102 fixedly arranged at the upper ends of the insulating pillars 101, a base 103 fixedly arranged below the insulating pillars 101, and further comprising: a control component 2 arranged below the base 103, used for controlling the rotation of the insulating pillars 101; a driven component 3 arranged between the insulating pillars 101, used for following the control component 2 to control the mirror image rotation of the insulating pillars 101; and an arc extinguishing component 4 arranged on one side of the insulating pillars 101, used for cooperating with the control component 2 to achieve arc extinguishing.

[0037] By setting a combination switch seat 1, a control component 2, a driven component 3 and an arc extinguishing component 4, the cooperation between the control component 2 and the driven component 3 can make the insulating pillars 101 in the combination switch seat 1 rotate in opposite directions to separate the connected conductive bars 102. Compared with the prior art, the closing and opening operations of the conductive bars 102 on the insulating pillars 101 can be realized more labor-savingly. The rainwater is collected and filtered and purified by the arc extinguishing component 4. When the power safety switch needs to be opened, the water mist in the arc extinguishing component 4 is sprayed when the conductive bars 102 are rotated by the control component 2, and the arc generated between the conductive bars 102 is quickly cooled down, thereby eliminating the arc. In addition, the rainwater stored in the control component 2 can also absorb part of the heat generated by the combination switch seat 1 during operation, thereby reducing the risk of safety accidents caused by high temperature generated by the combination switch seat 1.

[0038] In one embodiment, the control assembly 2 includes a control box 201 and a control handle 202, one end of the control handle 202 passes through the side wall of the control box 201, the other end of the control handle 202 is fixedly provided with a rotating shaft 203, one end of the rotating shaft 203 is provided with a transmission belt 204, and the other end of the transmission belt 204 is provided with a gear 1 205;

[0039] A gear 2 206 is provided on one side of the gear 1 205, a gear 3 207 is fixedly provided above the gear 2 206 via a connecting shaft, a gear 4 208 is provided on one side of the gear 3 207, a transmission shaft 209 is fixedly provided on the upper end of the gear 4 208, the gear 1 205, the gear 2 206, the gear 3 207 and the gear 4 208 are all rotatably connected to the control box 201, wherein the gear 2 206 rotates coaxially with the gear 3 207, the gear 1 205 is meshed with the gear 2 206, and the gear 3 207 is meshed with the gear 4 208.

[0040] With this design, when the control handle 202 is rotated, the control handle 202 will drive the rotating shaft 203 to rotate, and the rotating shaft 203 will drive the gear 1 205 to rotate through the transmission belt 204. The rotation of gear 1 205 will drive the gear 2 206 meshing therewith to rotate, and the rotation of gear 2 206 will drive the gear 3 207 coaxially rotating therewith, and the rotation of gear 3 207 will drive the gear 4 208 to rotate, and the gear 4 208 will drive the transmission shaft 209 to rotate. By multiple the gear ratio of gear 3 207 and gear 4 208, the control handle 202 end can be rotated with less effort.

[0041] In one embodiment, the driven component 3 includes a connecting block 301, a connecting rod 1 302 and a connecting rod 2 303. The connecting block 301 is fixedly set at one end of the transmission shaft 209. The connecting block 301 is rotatably connected to the connecting rod 1 302. The other end of the connecting rod 1 302 is rotatably set at the bottom of an insulating support 101 at one end. The connecting rod 2 303 is rotatably set between the insulating supports 101.

[0042] With this design, when the transmission shaft 209 rotates, the connecting block 301 will drive the connecting rod 1 302 to move, and the movement of the connecting rod 1 302 will drive the insulating support 101 at one end to rotate. When the insulating support 101 on one side rotates slowly, the connecting rod 2 303 will drive the insulating support 101 at the other end to rotate in the opposite direction, so that the conductive strips 102 on the two insulating supports 101 can be disconnected.

[0043] In one embodiment, the arc extinguishing assembly 4 includes a collection box 401 and a fixed column 402 fixedly arranged at the bottom of the collection box 401. A filter plate 1 403 and a filter plate 2 404 are fixedly arranged inside the collection box 401. A sprayer 405 is fixedly arranged below the filter plate 2 404. One end of the sprayer 405 penetrates the side wall of the collection box 401. A partition plate 406 is slidably arranged inside the collection box 401. The partition plate 406 is arranged in an F shape between the filter plate 1 403 and the filter plate 2 404. A control key 4051 is arranged on one side of the sprayer 405. The sprayer 405 is a prior art. When the control key 4051 is pressed, water mist will be sprayed, and its upper end will pass through the collection box 40 1 collects rainwater into the cavity, which will not be described in detail here; the collection box 401 is internally rotatably provided with a connecting shaft 1 407 and a connecting shaft 2 408, and both ends of the connecting shaft 1 407 and the connecting shaft 2 408 are provided with a bevel gear set, one end of the connecting shaft 1 407 is rotatably connected to the transmission shaft 209 through the bevel gear set, and the other end of the connecting shaft 1 407 is also rotatably connected to the connecting shaft 2 408 through the bevel gear set, and the collection box 401 is internally rotatably provided with a threaded rod 409, one end of the threaded rod 409 is rotatably connected to the connecting shaft 2 408 through the bevel gear set, and the outer wall of the threaded rod 409 is provided with a threaded ring 410, and the threaded ring 410 is fixedly connected to the lower end of the partition 406.

[0044] With this design, when the power safety switch is in a rainy area for a long time, rainwater enters the internal space of the collection box 401 and the inside of the sprayer 405 through the filter plate 1 403 and the filter plate 2 404 in the collection box 401. The side wall of the collection box 401 is made of brass, which has excellent thermal conductivity. When overload heat is generated between the insulating support 101 and the conductive strip 102, the heat can be collected through the collection box 401 and the filtered rainwater therein. When the control handle 202 is turned to perform the opening operation, the transmission shaft 209 rotates and drives the connecting shaft 1 407 and the connecting shaft 2 408 to rotate through the bevel gear set, thereby driving the threaded rod 409 to rotate. When the threaded rod 409 rotates, the threaded ring 410 and the partition 406 thereon will be driven to move to one end, and the partition 406 will start to clean the filter plate 1 403 and the filter plate 2 404 in the collection box 401. When the partition 406 passes through the sprayer 4 05, when the control key 4051 on the sprayer 405 is pressed, the conductive strips 102 are about to separate, and an arc will appear between the conductive strips 102. The control key 4051 will control the sprayer 405 to spray water mist between the conductive strips 102, thereby quickly cooling down the arc and eliminating it. When the control handle 202 rotates in the opposite direction, the transmission shaft 209 rotates in the opposite direction accordingly. As mentioned above, the transmission components rotate in the opposite direction. When the conductive strips 102 are about to contact, an arc will appear between the conductive strips 102. At this time, the travel of the partition 406 is about to hit the control key 4051 on the sprayer 405. After the partition 406 hits the control key 4051, the sprayed water mist will quickly cool down and eliminate the arc between the conductive strips 102, thereby achieving safe elimination of the arc generated when the conductive strips 102 are separated and contacted. By automatically eliminating the arc when opening and closing the switch, the safety hazards of high-voltage power switches are greatly reduced.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
