Abstract
The invention relates to a spring mechanism connectionless switching-on driving structure for a high voltage vacuum circuit breaker, which comprises a spring mechanism and a circuit breaker spindle. A pawl is sleeved on an output shaft of the spring mechanism; a crank arm is sleeved on the circuit breaker spindle; on end of the crank arm is provided with a roller; the other end of the crank arm is connected with a switching-on mechanism of the circuit breaker; and when a switching-on spring of the spring mechanism releases energy, the output shaft of the spring mechanism rotates to drive the pawl to collide the roller so as to ensure the circuit breaker spindle to rotate to implement switching-on. According to the invention, the connection link is structurally abolished, so that not only are parts reduced, but also the space is saved.
Description
Technical field
The present invention relates to high-pressure vacuum breaker spring mechanism technical field, particularly relate to a kind of spring mechanism for high-pressure vacuum breaker without connecting the combined floodgate Drive Structure.
Background technology
Existing circuit breaker has become the large branch of one in the outdoor switch device, and wherein vacuum circuit-breaker accounts for more than 90%, because its unique superiority is accepted extensively by the user.Outdoor vacuum circuit breaker product type class is numerous, and is domestic mainly take ZW8-12, ZW20-12, ZW32-12 etc. as main.Its actuating mode of opinion roughly can be summarized as spring mechanism, permanent magnet mechanism and man-operating mechanism etc., and wherein the application of spring mechanism is the most general, accounts for more than 80% in the 10kV outdoor vacuum circuit breaker.
The combined floodgate mode of conventional spring mechanism all adopts connecting rod to drive bar none, and namely when operating mechanism received reclosing command, energy-stored spring released energy and drive link at once, promotes main shaft and makes breaker closing.As shown in Figure 1, after spring mechanism 1 is received reclosing command, the combined floodgate spring of spring mechanism 1 releases energy, counterclockwise motion of cam 9, push roller 6 and drive driving connecting lever 10 and move clockwise, breaker main shaft 3 drives driver plate 11 again under the ordering about of connecting lever 10, driver plate 11 moves upward, and just can make circuit breaker 8 finish the combined floodgate program.Intrinsic its advantage of this traditional type of drive, but also have obvious weak point, for example: behind the necessary installing connecting rods, circuit breaker could move, and is not suitable with the development trend of current circuit breaker design modularized design; The connecting rod cracking phenomenon happens occasionally, and brings hidden danger to safe operation; The use of connecting rod strengthens space hold, the workload when having increased simultaneously the circuit breaker debugging; Part is many, and mechanism's dismounting is loaded down with trivial details, the field service difficulty.
Summary of the invention
Technical problem to be solved by this invention provides a kind of spring mechanism for high-pressure vacuum breaker without connecting the combined floodgate Drive Structure, can reduce part and save the space.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of spring mechanism for high-pressure vacuum breaker without connecting the combined floodgate Drive Structure, comprise spring mechanism and breaker main shaft, cover has sincere son on the output shaft of described spring mechanism; Cover has connecting lever on the described breaker main shaft, and an end of described connecting lever is provided with roller, and the other end links to each other with the switching-on mechanism of circuit breaker; When the combined floodgate spring of described spring mechanism released energy, the output shaft of spring mechanism rotarily drove the sincere son described roller of bump so that the breaker main shaft rotation realizes closing a floodgate.
Described sincere attached bag is drawn together sleeve, the first arm and the second arm, and described the first arm and the second arm are positioned at the both sides of sleeve.
Angle between described the first arm and the second arm is the 100-120 degree.
Angle between described the first arm and the second arm is 107 degree.
Wherein, making process directly clashes into main shaft B phase roller by the sincere son of mechanism's main shaft to be finished, and after spring mechanism released energy, output shaft was rotated in a clockwise direction 107 degree.
Beneficial effect
Owing to having adopted above-mentioned technical scheme, the present invention compared with prior art, have following advantage and good effect: the present invention has structurally cancelled connecting link, namely reduce part and saved again the space, it is reasonable in design, succinct, volume compact directly perceived, without governing loop, greatly improve the reliability of mechanism, reduced part, can save material, reduce processing cost; The present invention realizes separating of circuit breaker and spring mechanism, becomes separately two large standalone modules, becomes again integrated module after fitting together.Adopt modularized design, can optimize assembly technology, enhance productivity.
Description of drawings
Fig. 1 is spring mechanism combined floodgate driving mechanism schematic diagram of the prior art;
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiments of the present invention relate to a kind of spring mechanism for high-pressure vacuum breaker without connecting the combined floodgate Drive Structure, as shown in Figure 2, comprise spring mechanism 1 and breaker main shaft 3, and cover has sincere sub 4 on the output shaft 2 of described spring mechanism 1; Cover has connecting lever 5 on the described breaker main shaft 3, and an end of described connecting lever 5 is provided with roller 6, and the other end links to each other with the switching-on mechanism 7 of circuit breaker 8; When the combined floodgate spring of described spring mechanism 1 released energy, the output shaft 2 of spring mechanism 1 rotarily drove the sincere sub 4 described rollers 6 of bump so that breaker main shaft 3 rotations realize closing a floodgate.Wherein, described sincere sub 4 comprise sleeve, the first arm and the second arm, and described the first arm and the second arm are positioned at the both sides of sleeve, and the angle between described the first arm and the second arm is the 100-120 degree, are preferably 107 degree.
After spring mechanism is received reclosing command, the combined floodgate spring of spring mechanism releases energy, after the output shaft that orders about spring mechanism is rotated in a clockwise direction 107 degree, sincere son strikes the roller on the breaker main shaft B phase connecting lever, so that breaker main shaft counterclockwise rotates, finish the combined floodgate program thereby drive connecting lever driving switching-on mechanism.
Be not difficult to find, the present invention has structurally cancelled connecting link, has namely reduced part and has saved again the space, it is reasonable in design, succinct, volume compact directly perceived, without governing loop, greatly improve the reliability of mechanism, reduced part, can save material, reduce processing cost; The present invention realizes separating of circuit breaker and spring mechanism, and two large parts separate fully, become separately two large standalone modules, become again integrated module after fitting together.Adopt modularized design, can optimize assembly technology, enhance productivity.
