Description
Technical field
The utility model belongs to vacuum contactor structure-design technique field, is specifically related to a kind of quick box one pole vacuum contactor.
Background technology
In current electric power system, high, in, what lv contactor and circuit breaker used is all electromagnetic type divide-shut brake, the speed of electromagnetism divide-shut brake mainly leans on the volume size of coil and magnet to realize, because vacuum contact carrys out arc extinguishing by vacuum tube, vacuum tube presses bullet to form by self-closing power and contact, the vacuum contactor that conventional electric power uses, all press bullet and separating brake reaction spring for mentality of designing with contact in design, so design coil and magnet volume larger, vacuum tube could be shifted onto closing position, because the power promoted is greater than the self-closing power of vacuum tube, contact pressure elastic force also has reaction spring power summation.The larger closing time of coil is longer, and because electromagnet coil has the existence of inductance, the size of inductance concerns the speed of contact closing time.
The conventional contact of domestic market can not meet the new industries such as present photovoltaic solar, wind power generation.Because these emerging generatings are carried out under not power-off when being connected to the grid.Contactor is exactly its grid-connected key element, so require high to contactor closing time, must control at below 3m/s, conventional contact cannot realize.
Utility model content
The purpose of this utility model is to provide a kind of quick box one pole vacuum contactor of rapid closing.
The technical scheme realizing the utility model object is: a kind of quick box one pole vacuum contactor, comprise insulation shell, vacuum switch tube be in the housing set, two electrical terminals be connected respectively with vacuum switch tube two electrode be arranged on housing, arrange the insulated tension pole be connected with vacuum switch tube moving contact in the housing, for drive insulated tension pole carry out divide-shut brake action lever, for driving lever to carry out the brake separating mechanism of separating brake action, the switching-on mechanism for driving lever to carry out feed motion; Switching-on mechanism comprise rotate arrange in the housing for driving the driving lever of lever rotation and the combined floodgate drive link for driving driving lever to rotate, combined floodgate drive link stretches out housing as closing by hand button away from one end of driving lever; Brake separating mechanism comprise setting in the housing for driving the electromagnetic release mechanism of lever rotation and the separating brake drive link for triggering the action of electromagnetism uncoupling rigging, the outboard end of separating brake drive link stretches out housing as manual brake separating button.
In such scheme, lever is arranged on insulation shell inwall away from one end rotation of brake separating mechanism.
In such scheme, combined floodgate drive link and separating brake drive link be arranged in parallel.
In such scheme, be also provided with combined floodgate secondary spring in insulation shell, the two ends of combined floodgate secondary spring are connected on insulation shell inwall and lever respectively.
In such scheme, combined floodgate secondary spring is disc spring.
In such scheme, also comprise the adjustment screw for regulating combined floodgate secondary spring coefficient of elasticity.
The utility model has positive effect: (1) spring closing speed is fast, spring force is adjustable, add the negative pressure of vacuum tube, closing speed can reach below 1m/s and spring combined floodgate rear spring pressure is directly pressed on vacuum tube, and combined floodgate contact pressure is large, closes a floodgate without bounce time, and loop resistance is little, switching-in spring adopts butterfly spring, and pressure is more stable, easy to adjust.(2) separating brake manual brake separating is by arm of force ratio, makes hand point dynamics less, owing to keeping hook dynamics little, so electromagnet stroke is also little, as long as electromagnet promotes to keep hook to thread off just complete combined floodgate.Because electromagnet volume is little, coil turn is few, and inductance is also very little.We overcome the reverse electrodynamic type of electromagnet by inverse item Design Thinking, and electromagnet run duration is shortened.(3) method adopting insulation connecting lever and switching-on mechanism to separate, open position withstands switching-in spring by keeping hook, as long as make maintenance hook thread off during combined floodgate, vacuum tube just can under the effect of switching-in spring and vacuum tube negative pressure rapid closing, because the material amounts such as vacuum tube moved end connecting lever are less, so closing speed can reach maximum, whole closing time reaches below 3m/s, and without closing rebound.For solar energy, wind-electricity integration solve a great problem, also fill up this blank of China's power industry.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 is a kind of structural representation of the present utility model, shows a kind of embodiment of the present utility model.
The present embodiment is a kind of quick box one pole vacuum contactor, as shown in Figure 1, comprise insulation shell 1, vacuum switch tube 2 be in the housing set, two electrical terminals 3 be connected respectively with vacuum switch tube two electrode be arranged on housing, arrange the insulated tension pole 4 be connected with vacuum switch tube moving contact in the housing, for drive insulated tension pole carry out divide-shut brake action lever 5, for driving lever to carry out the brake separating mechanism 6 of separating brake action, the switching-on mechanism 7 for driving lever to carry out feed motion; Switching-on mechanism comprise rotate arrange in the housing for driving the driving lever 61 of lever rotation and the combined floodgate drive link 62 for driving driving lever to rotate, combined floodgate drive link stretches out housing as closing by hand button 63 away from one end of driving lever; Brake separating mechanism comprise setting in the housing for driving the electromagnetic release mechanism 71 of lever rotation and the separating brake drive link 72 for triggering the action of electromagnetism uncoupling rigging, the outboard end of separating brake drive link stretches out housing as manual brake separating button 73.
Lever is arranged on insulation shell inwall away from one end rotation of brake separating mechanism.Combined floodgate drive link and separating brake drive link be arranged in parallel.
Combined floodgate secondary spring 8 is also provided with and for regulating the adjustment screw 81 of combined floodgate secondary spring coefficient of elasticity, the two ends of combined floodgate secondary spring are connected on insulation shell inwall and lever respectively in insulation shell.Combined floodgate secondary spring preferably adopts disc spring.
The present embodiment has positive effect: (1) spring closing speed is fast, spring force is adjustable, add the negative pressure of vacuum tube, closing speed can reach below 1m/s and spring combined floodgate rear spring pressure is directly pressed on vacuum tube, and combined floodgate contact pressure is large, closes a floodgate without bounce time, and loop resistance is little, switching-in spring adopts butterfly spring, and pressure is more stable, easy to adjust.(2) separating brake manual brake separating is by arm of force ratio, makes hand point dynamics less, owing to keeping hook dynamics little, so electromagnet stroke is also little, as long as electromagnet promotes to keep hook to thread off just complete combined floodgate.Because electromagnet volume is little, coil turn is few, and inductance is also very little.We overcome the reverse electrodynamic type of electromagnet by inverse item Design Thinking, and electromagnet run duration is shortened.(3) method adopting insulation connecting lever and switching-on mechanism to separate, open position withstands switching-in spring by keeping hook, as long as make maintenance hook thread off during combined floodgate, vacuum tube just can under the effect of switching-in spring and vacuum tube negative pressure rapid closing, because the material amounts such as vacuum tube moved end connecting lever are less, so closing speed can reach maximum, whole closing time reaches below 3m/s, and without closing rebound.For solar energy, wind-electricity integration solve a great problem, also fill up this blank of China's power industry.
