Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Embodiments of the present invention relate to permanent magnetism in a kind of outdoor three-phase column vacuum breaker and spring dual operation mechanisms, as shown in Figure 1, comprise vacuum circuit-breaker 1, permanent magnet mechanism 5, spring mechanism 8 and casing 2, described vacuum circuit-breaker 1 is arranged on above casing 2, and described permanent magnet mechanism 5 and described spring mechanism 8 are independently arranged in described casing 2; Described permanent magnet mechanism 5 performs electronic separating brake and electric switch-on operational order, and described spring mechanism 8 performs closing by hand operational order; The described outside side of casing 2 is provided with the switch lever 9 for energy storage and combined floodgate, and its installation site as shown in Figure 2.Wherein, described permanent magnet mechanism 5 is connected on drive link 3 by yoke plate 4, relies on DC power supply to provide energy; Described drive link 3 completes the motion process driving described vacuum circuit-breaker 1 on/off switch.Described spring mechanism 8 connecting lever 6 is connected on drive link 3, relies on and manually makes described switching-in spring 7 lay in and release energy; When switch lever 9 come and go downwards pull time, described switching-in spring 7 crosses summit, and energy abrupt release, realizes described vacuum circuit-breaker 1 rapid closing.
As shown in Figure 3, described spring mechanism 8 comprises switching-in spring 7 and ratchet 10, and described switching-in spring 7 is connected with ratchet 10, and described ratchet 10 is provided with holds up son 11 for what locate; Described ratchet 10 is provided with cam 12, described cam 12 and connecting lever 6 tangent; Described switch lever 9 is connected with the rotating shaft of ratchet 10.Pumped by switch lever 9, ratchet 10 is made to drive switching-in spring 7 stored energy, when switching-in spring 7 often draws high one section, all by sincere sub 11 location on ratchet 10, when switching-in spring 7 is progressively elongated and moves to vertex position, energy discharges at once, under the driving of cam 12, overcome the confining force of sluice separating spring by drive link and compress excess of stroke spring simultaneously, auxiliary switch switches, and now whether permanent magnet coil is charged can keep closing position, completes the making process of circuit breaker.For the permanent magnet mechanism of 20kA circuit breaker, switching-in spring, except the 800N that sluice separating spring will be stretched, also will provide and be enough to make three-phase overtravel spring compress the 3000N put in place.Therefore two power together should be counted during switching-in spring design, simultaneously in order to take into account closing speed, so after the redesign by exporting usefulness and transformational structure to mechanism, switching-in spring summit pulling force fixes on 2600N, is defined as 4200N after considering rich degree.Wherein, the rotating shaft of the ratchet of energy storage is extended to the correct position outside casing, install a switch lever for energy storage, its stored energy operation power is less than 50N, just can carry out manual operation easily.
The present invention the described vacuum circuit-breaker by described permanent magnet mechanism actuating keep original function, do not change described box sizes prerequisite under, design a set of described spring mechanism in addition and provide a kind of manual rapid closing function for it: described spring mechanism, connecting lever, drive rod are connected, described switch lever comes and goes downwards and pulls, when switching-in spring crosses summit, energy abrupt release, realizes described vacuum circuit-breaker rapid closing.The switching force of described spring mechanism is greater than and sluice separating spring is drawn high two of putting and compressing three-phase overtravel spring in place and make a concerted effort.The closing speed of described dual operation mechanisms can reach 0.6 ± 0.2m/s respectively, within the closing rebound of described dual operation mechanisms can reach 2ms respectively, meets the requirement that it cut-offs short circuit current 20kA.
Be not difficult to find, dual operation machine mentality of designing of the present invention makes every effort to simple, with clearly defined objective: small-sized reliable, the structural module of its man-operating mechanism, decreases many loaded down with trivial details links and parts, such as in mechanism design, do not consider the part etc. installing separating brake and reclosing system; Pull handle just can realize manual rapid closing; Under the prerequisite not changing original box sizes, utilize remaining space to be in place easily, do not hinder again assembling and the debugging of switch simultaneously; Dual-mechanism block combiner separately i.e. independent but also interdependence, non-interference during operation.It is every electrically and the technical requirement of mechanical parameter that dual operation machine design meets vacuum circuit-breaker completely, reaches expection object.
