Description

The anti-incorrect manipulation deadlock structure of on-load switch
Technical field
The utility model belongs to the technical field of electric equipment, is specifically related to a kind of anti-incorrect manipulation deadlock structure of on-load switch.
Background technology
Electrical load switch is provided with operating axis, the opening and closing state of the rotation control overhead switch of operating axis, and namely after operating axis rotates clockwise certain angle arrival closing position from open position, on-load switch is just in "on" position; Otherwise after operating axis rotates counterclockwise certain angle arrival open position from closing position, on-load switch is just in gate-dividing state.In order to turn operating axis, also outside operating axis, be socketed with T-shaped operating grip, operating grip comprises longitudinal axle sleeve and transverse bar, and longitudinal axle sleeve is fixedly connected with transverse bar becomes T-shaped.Under normal circumstances, operating grip and operating axis depart from, and when needs turn operating axis, is enclosed within by longitudinal axle sleeve outside operating axis end, after turning, again extracted from operating axis end by longitudinal axle sleeve of operating grip.
On-load switch closes a floodgate or in separating brake process, if separating brake or closing speed too low, can electric arc be produced, shorten contact useful life, the accident such as contact burning, blast even occurs, therefore require to close a floodgate or separating brake is swift in motion simply.Be swift in motion simply to make divide-shut brake, people devise the spring assist jump mechanism shown in Fig. 1, Fig. 2, Fig. 3: operating axis 3 side is provided with swingable spring base 41, operating axis 3 is connected with the rotating disk 5 of synchronous axial system, the eccentric position of rotating disk 5 is provided with eccentric rod 6, eccentric rod 6 be axially parallel to operating axis 3, be provided with compression spring 4 between spring base 41 and eccentric rod 6; When operating axis 3 rotates counterclockwise the process of the gate-dividing state shown in Fig. 3 from the "on" position shown in Fig. 1, the intermediateness turned over shown in Fig. 2 must be needed, forwarding in the process of state shown in Fig. 2 counterclockwise from state shown in Fig. 1, spring 4 energy storage by compressing, and forwarding in the process of state shown in Fig. 3 counterclockwise from state shown in Fig. 2, spring releases energy and operating axis 3 is pushed rapidly to open position, realizes quick acting switching-off thus; Similar and the direction of rotation of the operating principle of rapid closing.Therefore, spring assist jump mechanism not only can realize quick divide-shut brake, also can increase contact laminate pressure.
But above-mentioned spring assist jump mechanism although solve can the problem of divide-shut brake fast, but also bring another problem: in supply line simultaneously, when electric equipment or on-load switch itself break down, need on-load switch can urgent automatic brake separating, and can not wait for and just utilize operating grip to carry out manual brake separating operation after operating personnel show up, but operating axis is rotating counterclockwise in the process of the intermediateness shown in Fig. 2 from the "on" position shown in Fig. 1, obviously need to overcome very large spring resistance, on the other hand, although on-load switch is when inartificial participation, certain automatic reaction action (elasticity thimble can be made after such as blown fuse to produce mobile) can be produced due to above-mentioned failure problems, but the strength of these automatic reaction actions is far not enough to overcome above-mentioned spring resistance.For this reason, people devise again following measures scheme: the intermediateness of on-load switch shown in Fig. 2 is provided with and makes operating axis suspend the locking mechanism rotated, when operating axis turns to the intermediateness shown in Fig. 2, because the central axis of spring and the central axis of operating axis are positioned at same plane, the moment that spring promotion operating axis rotates clockwise is zero, the moment that spring promotion operating axis rotates counterclockwise also is zero, namely balance is reached, therefore the card power very little (just can keep operating axis suspend) of locking needed for mechanism, when needs operating axis rotates, the power overcome needed for locking mechanism resistance is also very little.Owing to there being said mechanism, after operating axis rotates clockwise closing position, operating axis is rotated counterclockwise the intermediateness shown in Fig. 2 by operating personnel again, then operating grip is departed from, operating axis locking mechanism the effect of slight card power under, just rest on the middle shape position shown in Fig. 2, due to operating axis turn to this position time, operating axis stores comparatively macro-energy, because being just just called " energy storage position " this position in this journey; When needing emergency opening when meeting accident, the automatic reaction action that on-load switch produces due to failure problems slightly will promote rotating disk (comprising operating axis) and rotate counterclockwise, above-mentioned balance is broken, once balance broken a little after, spring rotates counterclockwise promoting rapidly operating axis, realize thus on-load switch can promptly automatically, quick acting switching-off.
But, applicant finds through practice, in use, after operating personnel's clockwise turning operation axle closes a floodgate, often forget and carry out reverse energy pre-storage operation (namely operating axis being rotated counterclockwise energy storage position from closing position), therefore, when on-load switch operating axis is in closing position, when if supply line, electric equipment or on-load switch itself break down, even if on-load switch self can produce the automatic reaction action of a series of generation, but still operating axis can not be made to rotate counterclockwise separating brake, therefore can lead to more major break down.
