[0001] The present application relates to the technical field of power systems, and more specifically, to an interlocking circuit breaker device. Background Art

[0002] Circuit breakers are usually used in power supply systems to cut off circuits to protect equipment in power supply systems. Circuit breakers can also be combined to form an interlocking circuit breaker device, including two circuit breakers and an interlocking device. The interlocking device can achieve mutual restriction and restraint between the two circuit breakers. The interlocking device of the related art usually includes a mechanical part and an electrical part. The mechanical part usually includes a gear, chain or slot block interlocking structure, which has a complex structure, high cost and poor reliability. Summary of the invention

[0003] An embodiment of the present application provides an interlocking circuit breaker device.

[0004] The interlocking circuit breaker device of the embodiment of the present application includes:

[0005] Two circuit breakers with fixed settings;

[0006] An interlocking link is rotatably arranged relative to the circuit breaker, and includes toggle sections at both ends. The interlocking link is configured to rotate when one of the toggle sections is pushed by the corresponding operating handle of the circuit breaker, so that the other toggle section toggles the corresponding operating handle of the circuit breaker in the opposite direction.

[0007] The interlocked circuit breaker device proposed in the present application is configured to rotate the interlocking link and enable the operating handle of the circuit breaker to push the interlocking link to rotate, so that when the operating handle of one circuit breaker is turned to push the interlocking link to rotate, the operating handle of the other circuit breaker will be turned in the opposite direction, thereby achieving the situation that the two circuit breakers cannot be closed or opened at the same time, thereby avoiding circuit failures or safety accidents in the power system caused by the simultaneous closing or opening of the two circuit breakers.

[0008] In certain embodiments, the interlocking link further comprises a rotating section, the rotating section is rotatably disposed between the two circuit breakers, and the two toggle sections are located at two ends of the rotating section.

[0009] In this way, when a toggle section is pushed by the operating handle, the turning force arm is the shortest, which is conducive to making the rotation more stable and allowing the toggle section to toggle the operating handle more effortlessly.

[0010] In some embodiments, the interlocked circuit breaker device includes a mounting base, which is arranged between the two circuit breakers and formed with a rotation groove, in which the rotation section is rotatably arranged, and the width of the rotation groove is substantially the same as the length of the rotation section and the distance between the two circuit breakers.

[0011] In this way, the length of the rotation groove can be maximized, making the rotation of the interlocking link more stable. At the same time, it can prevent the interlocking link from sliding along the rotation groove, causing the interlocking link to become stuck.

[0012] In certain embodiments, the interlock circuit breaker device further includes a limit pin, which is inserted into the mounting base to limit the rotating section within the rotating groove.

[0013] In this way, the limit pin is used to limit the interlocking link in the rotation groove to prevent the interlocking link from escaping from the rotation groove.

[0014] In some embodiments, the number of the limit pins is at least two, and the at least two limit pins are arranged along the length direction of the rotating section, and the length direction of the limit pins is substantially perpendicular to the length direction of the rotating section.

[0015] In this way, the two limit pins can prevent the interlocking link from tilting in the rotation groove.

[0016] In some embodiments, the axes of the two toggle sections and the rotating section are substantially located in the same plane and substantially parallel to each other, and the two toggle sections are located on both sides of the rotating section;

[0017] The operating handle includes a rotating column and a paddle extending radially outward from the rotating column, the rotating columns of the two operating handles are aligned, the axes of the two toggle sections are basically parallel to the rotating axes of the rotating column and are located on the same side of the two paddles, one of the toggle sections is located at the halfway point of the corresponding paddle stroke, and the other toggle section is located at the end of the stroke of the corresponding paddle.

[0018] In this way, when the operating handle is moved in a first direction, the paddle pushes the toggle section to rotate the interlocking link, and the other toggle section will toggle the corresponding paddle to move the operating handle in a second direction. The first direction and the second direction are opposite, so that the operating handles of the two circuit breakers cannot be moved to the same side.

[0019] In some embodiments, the interlocking link also includes a connecting section, which respectively connects the two ends of the rotating section with the corresponding toggle section, and the connecting section includes a straight sub-segment and two arc sub-segments, and the two arc sub-segments respectively connect the rotating section with the straight sub-segment, and the toggle section with the straight sub-segment.

[0020] In this way, the arc sub-segment can increase the strength of the interlocking link and make the interlocking link easier to demould.

[0021] In some embodiments, the operating length of the toggle section and the corresponding operating handle is greater than half the width of the operating handle.

[0022] In this way, the contact area between the toggle section and the operating handle can be increased, and the length of the lever arm can be increased, so that the toggle section can more easily toggle the operating handle.

[0023] In some embodiments, the interlocking link is made of high-hardness steel.

[0024] In this way, the interlocking link can toggle the operating handle of the circuit breaker more stably.

[0025] In certain embodiments, the interlock circuit breaker device further comprises a slide rail, and the two circuit breakers are slidably disposed on the slide rail.

[0026] In this way, it is convenient to disassemble the circuit breaker and adjust the distance between the circuit breakers.

[0040] Circuit breakers are usually used in power supply systems to cut off circuits to protect equipment in power supply systems. Circuit breakers can also be combined to form an interlocking circuit breaker device, including two circuit breakers and an interlocking device. The interlocking device can achieve mutual restriction and restraint between the two circuit breakers. The interlocking device of the related art usually includes a mechanical part and an electrical part. The mechanical part usually includes a gear, chain or slot block interlocking structure, which has a complex structure, high cost and poor reliability.

[0041] See also Figure 1 The interlocking circuit breaker device 100 of the embodiment of the present application includes two fixed circuit breakers 10 and an interlocking link 20. The interlocking link 20 is rotatably arranged relative to the circuit breaker 10. The interlocking link 20 includes toggle sections 21 located at both ends. The interlocking link 20 is configured to rotate when one of the toggle sections 21 is pushed by the operating handle 11 of the corresponding circuit breaker 10, so that the other toggle section 21 toggles the operating handle 11 of the corresponding circuit breaker 10 in the opposite direction.

[0042] The interlocked circuit breaker device 100 proposed in the present application is configured to rotate the interlocking link 20, and the operating handle 11 of the circuit breaker 10 can push the interlocking link 20 to rotate, so that when the operating handle 11 of one circuit breaker 10 is turned to push the interlocking link 20 to rotate, the operating handle 11 of the other circuit breaker 10 will be turned in the opposite direction, so that the two circuit breakers 10 cannot be closed or opened at the same time, thereby avoiding circuit failures or safety accidents in the power system caused by the simultaneous closing or opening of the two circuit breakers 10.

[0043] Specifically, the circuit breaker 10 refers to a switch device that can close, carry and disconnect current under normal circuit conditions, and can close, carry and disconnect current under abnormal circuit conditions within a specified time. It is an important control and protection device in the power system, which can ensure the safe operation of the power system and prevent equipment damage and electrical fires.

[0044] In the embodiment of the present application, when one of the circuit breakers 10 is closed, when the other circuit breaker 10 is performing a closing operation, its operating handle 11 will push the corresponding toggle section 21 to rotate the interlocking link 20, so that the other toggle section 21 toggles the operating handle 11 of the corresponding circuit breaker 10 in the opposite direction, and finally disconnects the originally closed circuit breaker 10, thereby achieving the goal that the two circuit breakers 10 cannot be closed at the same time.

[0045] In other embodiments, the interlocking link 20 may also be configured such that when one of the circuit breakers 10 is disconnected, the operating handle 11 of the circuit breaker 10 pushes a toggle section 21 to rotate the interlocking link 20, so that the other toggle section 21 toggles the operating handle 11 of the corresponding circuit breaker 10 in the opposite direction, and finally closes the other circuit breaker 10, thereby achieving the goal that the two circuit breakers 10 cannot be disconnected at the same time.

[0046] In some embodiments, the interlocking link 20 may also be provided with three toggle sections 21, and the three toggle sections 21 are corresponding to three circuit breakers 10. The interlocking link 20 is configured to rotate when one of the toggle sections 21 is pushed by the operating handle 11 of the corresponding circuit breaker 10, so that the remaining one or two toggle sections 21 toggle the operating handle 11 of the corresponding circuit breaker 10 in the opposite direction.

[0047] In some embodiments, the interlocking link 20 may also be provided with other numbers of toggle sections 21, and the same number of circuit breakers 10 may be provided corresponding to the number of toggle sections 21. The specific numbers of toggle sections 21 and circuit breakers 10 may be adjusted according to actual needs and will not be elaborated herein.

[0048] See also Figures 1 to 3 In some embodiments, the interlocking link 20 further includes a rotating section 22 , which is rotatably disposed between the two circuit breakers 10 , and the two toggle sections 21 are located at both ends of the rotating section 22 .

[0049] In this way, when a toggle section 21 is pushed by the operating handle 11 , the turning force arm is the shortest, which is conducive to making the rotation more stable, so that the toggle section 21 can toggle the operating handle 11 more effortlessly.

[0050] Specifically, in the embodiment of the present application, the two toggle sections 21 and the rotating section 22 are both cylindrical with the same diameter, the interlocking link 20 is symmetrical about the center, the two toggle sections 21 are arranged at both ends of the rotating end, and the two toggle sections 21 are located on different sides of the two rotating ends.

[0051] In some embodiments, two rotating sections 22 may be provided. In this case, the two toggle sections 21 are provided in the middle, and the two rotating sections 22 are provided at both ends of the two toggle sections 21 and outside the two circuit breakers 10 .

[0052] See also Figure 1 and Figure 2 In some embodiments, the interlocked circuit breaker device 100 includes a mounting base 30, which is disposed between the two circuit breakers 10 and is formed with a rotation groove 31, in which the rotation section 22 is rotatably disposed, and the width of the rotation groove 31 is substantially the same as the length of the rotation section 22 and the distance between the two circuit breakers 10.

[0053] In this way, the length of the rotation slot 31 can be maximized, making the rotation of the interlocking link 20 more stable. At the same time, it can prevent the interlocking link 20 from sliding along the rotation slot 31 and causing the interlocking link 20 to get stuck.

[0054] Specifically, in the embodiment of the present application, the mounting base 30 is disposed between the two circuit breakers 10 for rotatably fixing the interlocking link 20 , and at the same time, the two circuit breakers 10 can also be separated.

[0055] In some embodiments, two mounting bases 30 may be provided, and two circuit breakers 10 are provided on two mounting bases 30. In this case, the interlocking link 20 needs to be provided with two rotating sections 22, and the two rotating sections 22 are respectively provided at both ends of the interlocking link 20, and the two rotating sections 22 are respectively rotatably provided on the two mounting bases 30. Furthermore, the two mounting bases 30 are both provided with rotating grooves 31, and the two rotating sections 22 are respectively rotatably provided in the two rotating grooves 31.

[0056] In the embodiment of the present application, the cross-section of the rotating groove 31 is U-shaped, so that the contact area between the rotating end and the rotating groove 31 can be larger, which is beneficial to the dispersion of stress. Furthermore, the width of the rotating groove 31 is slightly larger than the diameter of the rotating section 22, so that the rotating section 22 can be prevented from shaking radially in the rotating groove 31.

[0057] It is easy to understand that the vertical distance between the bottom surface of the rotating groove 31 and the first surface 12 at the top of the circuit breaker 10 is greater than the vertical distance between the axes of the rotating section 22 and the toggle section 21. In this way, when the interlocking link 20 rotates, the toggle section 21 will not interfere with the first surface to form a jam, thereby hindering the rotation of the interlocking link 20.

[0058] See also Figure 2 In some embodiments, the interlock circuit breaker device 100 further includes a limit pin 40 , which is inserted into the mounting base 30 to limit the rotating section 22 in the rotating groove 31 .

[0059] In this way, the limiting pin 40 is used to limit the interlocking link 20 in the rotation groove 31 to prevent the interlocking link 20 from escaping from the rotation groove 31 .

[0060] Specifically, in the embodiment of the present application, the rotating groove 31 includes a first side wall 311 and a second side wall 312, and the first side wall 311 is provided with a first through hole 3111 at the edge of the opening of the rotating groove 31, and the second side wall 312 is provided with a second through hole 3121 corresponding to the first through hole 3111 at the edge of the opening of the rotating groove 31, and the limiting pin 40 passes through the first through hole 3111 and the second through hole 3121 and is inserted into the mounting base 30 to limit the rotating section 22 in the rotating groove 31.

[0061] In some embodiments, the limiting pin 40 may be a bolt, and the limiting pin 40 passes through the first through hole 3111 and the second through hole 3121 and is fixed in the first through hole 3111 and the second through hole 3121 by a nut.

[0062] In some embodiments, the limiting pin 40 may also be a rivet. After the limiting pin 40 passes through the first through hole 3111 and the second through hole 3121 , it is riveted to the first side wall 311 and the second side wall 312 .

[0063] In some embodiments, the limiting pin 40 may not be used, and the interlocking circuit breaker device 100 may further include a cover plate, which is used to cover the opening of the rotating groove 31 to limit the rotating section 22 in the rotating groove 31. It is easy to understand that the interlocking circuit breaker device 100 also includes a fastener, and the cover plate is detachably mounted on the opening of the rotating groove 31 through the fastener.

[0064] See also Figure 4In some embodiments, a closing structure may be formed at the opening of the rotation groove 31. Specifically, a first protrusion 3112 protruding toward the second side wall 312 is provided at the edge of the first side wall 311 near the opening of the rotation groove 31, and a second protrusion 3122 protruding toward the first side wall 311 is provided at the edge of the second side wall 312 near the opening of the rotation groove 31. The first protrusion 3112 and the second protrusion 3122 form a closing structure to restrict the rotation section 22 in the rotation groove 31. It should be noted that the protruding range of the first protrusion 3112 and the second protrusion 3122 should not be too large, otherwise it will increase the difficulty of installing the rotation section 22, and this structure is not suitable for the case where the toggle section 21 is subjected to a large thrust. When the toggle section 21 is subjected to a large thrust, if the closing structure cannot resist the excessive thrust, the rotation section 22 will be pressed out of the rotation groove 31.

[0065] See also Figure 2 In some embodiments, the number of the limit pins 40 is at least two, and at least two limit pins 40 are arranged along the length direction of the rotating section 22 , and the length direction of the limit pins 40 is substantially perpendicular to the length direction of the rotating section 22 .

[0066] In this way, the two limiting pins 40 can prevent the interlocking link 20 from tilting up in the rotation groove 31 .

[0067] Specifically, in the embodiment of the present application, the number of the limiting pins 40 is two, and the two limiting pins 40 are arranged at both ends of the rotating groove 31 along the length direction of the rotating section 22 .

[0068] In other embodiments, the limit pins 40 may be provided in other numbers or at other positions. The specific number and installation positions of the limit pins 40 may be selected according to actual needs and will not be elaborated herein.

[0069] See also Figure 1 and Figure 3 In some embodiments, the axes of the two toggle sections 21 and the rotating section 22 are substantially located in the same plane and substantially parallel to each other, and the two toggle sections 21 are located on both sides of the rotating section 22;

[0070] The operating handle 11 includes a rotating column 111 and a paddle 112 extending radially outward from the rotating column 111. The rotating columns 111 of the two operating handles 11 are aligned, and the axes of the two toggle sections 21 are basically parallel to the rotating axes of the rotating column 111 and are located on the same side of the two paddles 112. One of the toggle sections 21 is located at the halfway point of the stroke of the corresponding paddle 112, and the other toggle section 21 is located at the end of the stroke of the corresponding paddle 112.

[0071] In this way, when the operating handle 11 is moved along the first direction, the paddle 112 pushes the toggle section 21 to rotate the interlocking link 20, and the other toggle section 21 will toggle the corresponding paddle 112 to move the operating handle 11 in the second direction. The first direction and the second direction are opposite, so that the operating handles 11 of the two circuit breakers 10 cannot be moved to the same side.

[0072] Specifically, in the embodiment of the present application, the axes of the two toggle sections 21 and the rotating section 22 are located in the same plane and are substantially parallel to each other, and the vertical distances from the axis of the rotating section 22 to the axes of the two toggle sections 21 are the same.

[0073] Furthermore, when one of the toggle sections 21 is located at the end of the stroke of the corresponding paddle 112, the toggle section 21 is pressed by the operating handle 11 of the corresponding circuit breaker 10 and fixed between the paddle 112 and the top surface of the circuit breaker 10. In this way, when the operating handle 11 of another circuit breaker 10 pushes the corresponding toggle section 21, the toggle section 21 on this side can toggle the corresponding operating handle 11 more stably and accurately.

[0074] In the embodiment of the present application, when one of the toggle sections 21 is located at the end of the stroke of the corresponding paddle 112, the corresponding toggle section 21 is pushed to the end of the stroke of the corresponding paddle 112, and the interlocking link 20 rotates to rotate the other toggle section 21 to a position where the corresponding paddle 112 is halfway along its stroke, and pushes the corresponding paddle 112 to rotate around the axis of the rotating column 111 to exceed the upright position. According to the characteristics of the circuit breaker 10, at this time, the operating handle 11 of the circuit breaker 10 will automatically fall to one side of its rotation direction, thereby completing the control of the other circuit breaker 10.

[0075] See also Figure 3 In some embodiments, the interlocking link 20 also includes a connecting segment 23, which respectively connects the two ends of the rotating segment 22 and the corresponding toggle segment 21, and the connecting segment 23 includes a straight segment 231 and two arc segments 232, and the two arc segments 232 respectively connect the rotating segment 22 and the straight segment 231, and the toggle segment 21 and the straight segment 231.

[0076] In this way, the arc sub-segment 232 can increase the strength of the interlocking link 20 and make the interlocking link 20 easier to demold.

[0077] Specifically, in the embodiment of the present application, the interlocking link 20 is an integral structure that is integrally machined and formed. Furthermore, the cross-sections of the arc sub-segment 232 and the straight sub-segment 231 are both circular, and the cross-sectional diameter is equal to that of the rotating segment 22 and the toggle segment 21 .

[0078] In other embodiments, the connecting section 23, the rotating section 22 and the toggle section 21 may be processed in sections and connected.

[0079] See also Figure 1 In some embodiments, the operating length of the toggle section 21 and the corresponding operating handle 11 is greater than half the width of the operating handle 11.

[0080] In this way, the contact area between the toggle section 21 and the operating handle 11 can be increased, and the length of the lever arm can be increased, so that the toggle section 21 can more easily toggle the operating handle 11 .

[0081] Specifically, in the embodiment of the present application, the operating length of the toggle section 21 and the corresponding operating handle 11 is the length of the toggle section 21. It is easy to understand that, under the premise that the length of the toggle section 21 does not exceed the width of the operating handle 11, the longer the length of the toggle section 21, the larger the contact area between the toggle section 21 and the operating handle 11, and the more dispersed the stress between the toggle section 21 and the operating handle 11, so that the toggle section 21 can more easily toggle the operating handle 11, and the action is more stable, and at the same time, it is helpful to reduce the strength requirement of the toggle section 21.

[0082] In some embodiments, the interlocking link 20 is made of high-hardness steel.

[0083] In this way, the interlocking link 20 can move the operating handle 11 of the circuit breaker 10 more stably.

[0084] Specifically, the interlocking link 20 is an integral structure of high-hardness steel integrally injection molded. In other embodiments, the interlocking link 20 may also be made of other materials with sufficient strength. The specific material of the interlocking link 20 may be selected according to actual strength requirements and will not be elaborated herein.

[0085] See also Figure 5 In some embodiments, the interlock circuit breaker device 100 further includes a slide rail 50 , and the two circuit breakers 10 are slidably disposed on the slide rail 50 .

[0086] In this way, the circuit breakers 10 can be disassembled easily and the distance between the circuit breakers 10 can be adjusted easily.

[0087] Specifically, in the embodiment of the present application, the slide rail 50 refers to a universal slide rail 50 in a distribution box or other power system. The slide rail 50 is a mounting platform for electrical equipment in the power system. Electrical equipment such as circuit breakers 10, disconnectors, etc. can be conveniently mounted on the slide rail 50, making the installation process faster and more efficient. At the same time, the slide rail 50 can firmly fix the electrical equipment to prevent it from shaking or shifting during operation, thereby ensuring the stable operation of the electrical equipment.

[0088] For further information, see Figure 5 and Figure 6A dovetail groove 313 is provided at the bottom of the mounting base 30, and the mounting base 30 is also slidably set on the slide rail 50. The slide rail 50 has snap-in edges 51 on both sides, and the snap-in edges 51 are snapped into the dovetail groove 313, so that the mounting base 30 is slidably installed on the slide rail 50.

[0089] The slide rail 50 is usually made of high-quality materials such as aluminum alloy or cold-rolled steel plate. These materials not only have high strength and corrosion resistance, but also ensure that the slide rail 50 maintains stable performance during long-term use.

[0090] In some embodiments, the slide rail 50 can also be set to be adjustable, that is, the slide rail 50 can be adjusted according to circuit breakers 10 of different sizes or shapes to adapt to diverse installation requirements. In this way, the power system can accommodate more types of electrical equipment and improve space utilization.

[0091] In some embodiments, the interlocked circuit breaker device 100 may also include other fixings. In this case, the mounting base 30 and the two circuit breakers 10 may also be fixed to the fixings by fastening components to achieve the installation and fixation of the base and the two circuit breakers 10. The types of specific fixings and fastening components can be selected according to actual needs and will not be elaborated herein.
