Abstract
The utility model relates to a spring mechanism coupling-free closing drive structure applied to a high-voltage vacuum circuit breaker. The spring mechanism coupling-free closing drive structure applied to the high-voltage vacuum circuit breaker comprises a spring mechanism and a circuit breaker main shaft. The output shaft of the spring mechanism is sleeved with a pawl. The circuit breaker main shaft is sleeved with a crank arm. One end of the crank arm is provided with a roller, and the other end is connected with a closing mechanism of the circuit breaker. When a closing spring of the spring mechanism releases energy, the output shaft of the spring mechanism rotates to drive the pawl to strike the roller, thus the circuit breaker main shaft rotates and closing is realized. According to the utility model, a coupling link is cancelled in structure, which reduces parts and saves space.
Description
Technical field
The utility model relates to high-pressure vacuum breaker spring mechanism technical field, particularly relates 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 in the utility model 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 scheme that its technical problem that solves the utility model adopts 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 adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model has structurally been 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 utility model realization circuit breaker separates with 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 utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Execution mode of the present utility model relates to a kind of spring mechanism for high-pressure vacuum breaker without connecting the combined floodgate Drive Structure, as shown in Figure 2, comprises 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 that the utility model has structurally been 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 utility model realization circuit breaker separates with 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.
