Description

Technical Field

[0001] This utility model relates to the field of outdoor high-voltage circuit breaker technology, and in particular to a structure for preventing accidental contact in circuit breakers. Background Technology

[0002] Outdoor high-voltage circuit breakers are high-voltage electrical switching devices installed in outdoor environments, primarily used for connecting, disconnecting, and protecting circuits in power transmission and distribution systems. They can quickly interrupt or close high-voltage currents under normal operating and fault conditions to ensure the safe and stable operation of power systems and equipment. Because they are directly exposed to the natural environment, outdoor high-voltage circuit breakers typically possess environmental adaptability capabilities against wind, rain, snow, dust, moisture, and corrosion. Their casing and insulation structure design must ensure protection against flashover, ultraviolet radiation, and aging.

[0003] Outdoor high-voltage circuit breakers, as indispensable switching equipment in power systems, are widely used in transmission and distribution lines and their control applications. Their opening and closing actions are typically achieved through a tripping control handle. Currently, when existing outdoor high-voltage circuit breakers operate in open areas such as outdoors, the tripping control handles used for opening or closing operations are often exposed on the outside of the control box. Furthermore, these handles lack protective structures to prevent accidental contact, making them susceptible to external factors such as wind, rain, dust, icing, bird damage, and human interference. There is also a risk of accidental contact or operational errors by unauthorized personnel. In the event of accidental contact or misoperation, the energized circuit breaker may open or close unexpectedly, leading to power system interruptions, equipment damage, and even serious personal injury accidents. Therefore, there are certain limitations and safety hazards in their use.

[0004] Based on this, we propose an anti-accidental-touch structure for circuit breakers to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an anti-accidental contact structure for circuit breakers, which can solve the problem that the existing outdoor high voltage circuit breaker tripping control handle is exposed and lacks an anti-accidental contact protection structure, making it susceptible to interference from external factors and accidental tripping or closing by personnel.

[0007] To solve the above-mentioned technical problems, this utility model provides an anti-accidental contact structure for circuit breakers, adopting the following technical solution: It includes a circuit breaker body, an anti-accidental contact component installed on one side of the circuit breaker body, several sets of vacuum arc-extinguishing components connected to the top of the circuit breaker body, a tripping indicator component installed on one side of the circuit breaker body, and a tripping control handle also provided on the side of the circuit breaker body near the tripping indicator component. The anti-accidental contact component includes a connecting part, which is installed on the outside of the tripping control handle, and a safety protection component is also provided on one side of the connecting part.

[0008] Optionally, the connecting component includes a support base, and an adjusting guide is installed in the middle of the support base.

[0009] Optionally, a fixing plate is installed on both sides of the support base, and a first embedded slot is opened in the middle of the inner side of both sets of fixing plates. Several sets of first positioning holes are opened on the side of the fixing plate near the first embedded slot.

[0010] Optionally, the adjusting guide includes an arc-shaped baffle frame that matches the structure of the trip control handle. The arc-shaped baffle frame and the trip control handle are in a transition fit. A second embedded slot is provided on one side of the arc-shaped baffle frame. First embedded plates are connected to both sides of the arc-shaped baffle frame. The first embedded plates and the first embedded slots are in a snap-fit ​​fit. Several sets of second positioning holes are also provided in the middle of the two sets of first embedded plates. The second positioning holes match the structure of the first positioning holes.

[0011] Optionally, the safety protection component includes an acrylic protective cover, one side of which is connected to a second embedded plate. The second embedded plate is structurally matched with the first embedded plate, and the second embedded plate and the first embedded plate are in a snap-fit ​​engagement.

[0012] Optionally, the acrylic protective cover is equipped with side plates on both sides near the second embedded plate. Several sets of positioning pins are connected to one side of each of the two sets of side plates. The positioning pins are matched with the structure of the first positioning hole and the second positioning hole, and the positioning pins are engaged with the first positioning hole and the second positioning hole.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. The circuit breaker anti-misoperation structure designed in this scheme, through the cooperation of connecting components with the support base and adjusting guide, as well as the transition cooperation between the arc-shaped retaining frame and the tripping control handle, can form a physical shield on the top outer side of the tripping control handle, preventing external environmental factors such as wind, rain, dust, snow, and bird damage from directly affecting the handle. At the same time, it restricts the movement trajectory of the handle during operation, achieving precise guidance of the tripping action. Through the above structural design, this scheme can not only effectively avoid unexpected tripping or closing caused by operator misoperation or improper operation, but also ensure the safety and stability of the circuit breaker during energized operation.

[0014] 2. The circuit breaker anti-misoperation structure designed in this scheme uses a safety protection component added to the outside of the connecting parts. This safety protection component includes an acrylic protective cover, side plates, and positioning pins. By using the interlocking action of the second embedded plate and the first embedded plate, the acrylic protective cover can be securely installed on the outside of the arc-shaped retaining frame, forming a protective sleeve for the trip control handle. This prevents accidental contact or operational errors caused by the exposed handle. The use of the positioning pin in conjunction with the first and second positioning holes further improves the connection stability between the acrylic protective cover and the arc-shaped retaining frame, and strengthens the connection between the arc-shaped retaining frame and the support base. This achieves the overall reliability and operational safety of the circuit breaker anti-misoperation structure, while significantly reducing the risk of power system failures caused by environmental factors or human error.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Refer to Figures 1 to 6 This utility model provides an embodiment of an anti-misoperation structure for a circuit breaker, comprising a circuit breaker body 1, an anti-misoperation component 2 installed on one side of the circuit breaker body 1, several sets of vacuum arc-extinguishing components 3 connected to the top of the circuit breaker body 1, a tripping indicator component 4 installed on one side of the circuit breaker body 1, and a tripping control handle 5 also provided on the side of the circuit breaker body 1 near the tripping indicator component 4. The anti-misoperation component 2 includes a connecting part 6, which is installed on the outside of the tripping control handle 5. A safety protection component 7 is also provided on one side of the connecting part 6. This anti-misoperation structure for the circuit breaker, through the cooperation of the connecting part 6 with the support base 8 and the adjusting guide 9, and the transition cooperation between the arc-shaped baffle 13 and the tripping control handle 5, can provide shielding protection for the top outside of the tripping control handle 5. At the same time, it can also limit and guide the movement trajectory of the tripping control handle 5 during the adjustment process, thereby preventing the handle from being accidentally operated and unexpectedly tripping or closing, and improving the safety and reliability of the circuit breaker operation.

[0020] The connecting component 6 includes a support base 8, with an adjusting guide 9 installed in the middle of the support base 8. Through the cooperation between the support base 8 and the adjusting guide 9, the connecting component 6 provides stable support and precise movement guidance for the tripping control handle 5, achieving the limiting and guiding effect on the handle's movement trajectory during operation. Fixing plates 10 are installed on both sides of the support base 8. A first embedded slot 11 is provided in the middle of the inner side of each of the two sets of fixing plates 10. Several sets of first positioning holes 12 are provided on the side of the fixing plate 10 near the first embedded slot 11. The first embedded slot 11 in the middle of the inner side of the fixing plate 10 is used for the embedded connection between the support base 8 and the adjusting guide 9. The adjusting guide 9 includes an arc-shaped baffle. 13. The arc-shaped baffle 13 is structurally matched with the trip control handle 5. The arc-shaped baffle 13 and the trip control handle 5 are in transition fit. A second embedded slot 14 is provided on one side of the arc-shaped baffle 13. A first embedded plate 15 is connected to both sides of the arc-shaped baffle 13. The first embedded plate 15 is structurally matched with the first embedded slot 11. The first embedded plate 15 and the first embedded slot 11 are in snap-fit ​​fit. Several sets of second positioning holes 16 are also provided in the middle of the two sets of first embedded plates 15. The second positioning holes 16 are structurally matched with the first positioning holes 12. Through the snap-fit ​​fit structure between the first embedded plate 15 and the first embedded slot 11, the arc-shaped baffle 13 can be firmly snapped and fixed inside the support base 8.

[0021] The safety protection component 7 includes an acrylic protective cover 17. A second embedded retaining plate 18 is connected to one side of the acrylic protective cover 17. The second embedded retaining plate 18 is structurally matched with the first embedded retaining plate 15, and the two plates are engaged in a snap-fit ​​connection. This snap-fit ​​design allows the acrylic protective cover 17 to be securely installed on the outside of the arc-shaped retaining frame 13, providing protection for the circuit breaker control handle 5 and preventing accidental contact or misoperation due to exposure. This improves the safety and reliability of circuit breaker operation. The acrylic protective cover 17 has side plates 19 installed on both sides near the second embedded plate 18. Several sets of positioning pins 20 are connected to one side of each of the two sets of side plates 19. The positioning pins 20 are structurally matched with the first positioning hole 12 and the second positioning hole 16. The positioning pins 20 are engaged with the first positioning hole 12 and the second positioning hole 16. Through the structural design of the engagement between the positioning pins 20 and the first positioning hole 12 and the second positioning hole 16, the connection stability between the acrylic protective cover 17 and the arc-shaped baffle 13 can be improved, and the connection between the arc-shaped baffle 13 and the support base 8 can also be strengthened.

[0022] Working Principle: The circuit breaker anti-misoperation structure designed in this scheme mainly consists of a connecting component 6 and a safety protection component 7. The connecting component 6 includes a support base 8 and an adjusting guide 9. The support base 8 is fitted with a first embedded slot 11 opened in the fixing plate 10 and first embedded plates 15 installed on both sides of the arc-shaped retaining frame 13. Since the first embedded plates 15 and the first embedded slot 11 are structurally matched and are interlocked, the arc-shaped retaining frame 13 with a second embedded slot 14 on one side can be interlocked and connected inside the support base 8. The support base 8 is used with fasteners such as bolts through the fixing plate 10 to fit and fix it on the outside of the circuit breaker body 1 with the tripping control handle 5. Since the arc-shaped retaining frame 13 and the tripping control handle 5 are structurally matched and are interlocked, the connecting component 6 not only provides shielding protection to the top outside of the tripping control handle 5, but also limits and guides the movement trajectory of the tripping control handle 5 during adjustment.

[0023] The circuit breaker anti-misoperation structure designed in this scheme can further improve the protection function by adding a safety protection component 7 to one side of the connecting component 6. The safety protection component 7 is composed of an acrylic protective cover 17 and side plates 19. By adding a second embedded plate 18 to one side of the acrylic protective cover 17, since the structure of the second embedded plate 18 matches that of the first embedded plate 15 and the two are in a snap-fit ​​fit, the acrylic protective cover 17 with side plates 19 on both sides can be snap-fitted to the outside of the arc-shaped baffle 13. The acrylic protective cover 17 installed on the outside of the arc-shaped baffle 13 can play a protective role for the trip control handle 5, and can prevent the trip control handle 5 from being exposed and causing erroneous operation problems such as accidental contact.

[0024] The circuit breaker anti-misoperation structure designed in this scheme improves the stability of the connection between the acrylic protective cover 17 and the arc-shaped baffle 13 by adding positioning pins 20 to the second embedded plates 18 on both sides of the acrylic protective cover 17. Since the positioning pins 20 are structurally matched with the first positioning hole 12 and the second positioning hole 16, and the positioning pins 20 are engaged with the first positioning hole 12 and the second positioning hole 16, the connection between the positioning pins 20 and the first positioning hole 12 and the second positioning hole 16 can be improved. At the same time, it can also strengthen the connection between the arc-shaped baffle 13 and the support base 8.
