One locked motor unit, the control signal that it receives from described authentication processing unit makes described primary cut-out body produce self-locking or release action.
Design philosophy of the present invention is suitable for existing primary cut-out, as oil circuit breaker (bulk-oil circuit-breaker, oil-minimum breaker), sulfur hexafluoride breaker (SF6 circuit breaker), vacuum circuit-breaker, compressed-air circuit breaker etc.
Wherein, described primary cut-out body comprises: a housing 10, described housing 10 is provided with at least one insulation vacuum 2, because high-tension line is three-phase normally, therefore three insulation vacuum 2 are arranged usually, and the outer end of described insulation vacuum 2 is respectively equipped with a leading-out terminal 21 and an end of incoming cables 22 that is connected with the external power circuit; One disjunction mechanism, it is arranged in the described housing, and in order to realize the separation and the feed motion of primary cut-out, it comprises: a power unit and a motor unit, described housing 10 is provided with a user input unit 11, in order to input locked password and unlocking pin.Described user input unit 11 comprises keyboard, and described keyboard can also can be a touch keyboard for physical keyboard.
Consult shown in Figure 2ly, it has the structural principle cutaway view of insulation vacuum of the primary cut-out of auto-lock function for the present invention; Described leading-out terminal 21 and end of incoming cables 22 are at described insulation vacuum 2 inner a corresponding movable contact piece 24 and stationary contact pieces 23 respectively; Simultaneously the structure of insulation vacuum of the present invention can have concrete conversion according to actual conditions, is that movable contact piece 24 is with 23 contacts of stationary contact piece with separate the principle that realizes circuit on-off but can not break away from above-mentioned principle type structure.
Consult Fig. 3 and shown in Figure 4, it is respectively the cutaway view that the present invention has the disjunction mechanism of body in the primary cut-out of auto-lock function, and the present invention has the three-dimensional exploded view of the disjunction mechanism of body in the primary cut-out of auto-lock function; Wherein, triggered for the motor unit in the described disjunction mechanism, and then realize the feed motion or the disjunction action of described movable contact piece 24 and described stationary contact piece 23, final conducting or the off-state that realizes circuit, since high-tension line together with requiring to finish in moment with disjunction, therefore be need be very big energy and power; And described power unit is in order to provide the power of instantaneous disjunction and combined floodgate to described motor unit.
Described motor unit comprises:
A main gangbar 40, it vertically is arranged in the described housing 10, in order to can realize one along action longitudinally in the housing, is provided with one between itself and the housing bottom and supports sliding part; Divide STATEMENT OF FEDERALLY SPONSORED 41, in the present embodiment be three groups (corresponding three-phases) its be slidingly connected with described main gangbar 40 respectively, concrete execution mode can be that described minute STATEMENT OF FEDERALLY SPONSORED 41 is provided with arc chute, described main gangbar 40 is installed with slide bar, described slide bar 41 can slide in the arc chute of described minute STATEMENT OF FEDERALLY SPONSORED 41, thereby when described main gangbar 40 lengthwise movements, pushing tow STATEMENT OF FEDERALLY SPONSORED 41 swings in described minute, and then make main gangbar 40 parts that are positioned at insulation vacuum 2 inside or the parts that are attached thereto produce action up and down, combine or disjunction between the final described movable contact piece 24 of pushing tow and the described stationary contact piece 23.
Wherein, described power unit is an elastic energy storage mechanism, and it comprises:
One rocking handle is arranged at the outside of housing, and the staff realizes energy storage (referring to shown in Figure 1) by the described rocking handle of swing; The two-stage gear transmission structure, i.e. primary pinion 43 and secondary gears 42, described rocking handle combines with described primary pinion 43, by the swing of described rocking handle, described primary pinion 43 is rotated; One swinging block 44, it combines with described secondary gears 42, and the upper end is connected with described main gangbar 40, and the number of teeth of significant described secondary gears 42 is the numbers of teeth much larger than primary pinion 43; One cam 46, itself and described swinging block 44 are coupling; Along with the spring leaf (not shown) of swinging block 44 inside is wound, thereby rotate; One jacking block (not shown), pushing tow be at described swinging block 44 lateral margins, thereby make the described swinging block 44 can be owing to the effect of the elastic restoring force of spring leaf is rotated; At least one first back-moving spring 45 is an example with a spring here, and it is connected with described cam 46, is stretched along with the rotation of cam 46; At least one second back-moving spring 471,472, here be example with two springs, it is connected with an end of described housing 10 respectively, its other end is connected with described main gangbar 40 by connecting rod, and wherein the coefficient of elasticity of first back-moving spring 45 is greater than the coefficient of elasticity of second back-moving spring 471,472.The user wants to close a floodgate, then need to continue the described rocking handle of swing, thereby described first back-moving spring 45 is stretched, and the spring leaf in the described swinging block 44 is again in energy storage, therefore the described main gangbar 40 of described first back-moving spring 45 pullings produces vertically action (as to second side) when triggering switch knob, thereby described the generation from STATEMENT OF FEDERALLY SPONSORED 41 moved, finally realize the feed motion of primary cut-out.
See also shown in Figure 5ly, it sets locked motor unit cross-sectional schematic for the primary cut-out that the present invention has auto-lock function;
Described locked motor unit with primary cut-out of auto-lock function comprises: an electromagnet 51, and its armature end 511 is corresponding with a trigger end 441 of described jacking block; Described electromagnet can be the electromagnet for the magnetic freeze mode.At the armature end pushing tow of described electromagnet 51 during to described trigger end 441, described jacking block separates with described swinging block 44, thereby effect in the elastic restoring force of contained spring sheet, and under the effect of second back-moving spring 471,472 that is drawn high, described main gangbar 40 produces vertically action (as to first side), thereby described the generation from STATEMENT OF FEDERALLY SPONSORED 41 moved, finally realize the disjunction action of primary cut-out.
One control circuit, it receives described control signal, thereby controls the "on" position of described electromagnet coil.
Because described electromagnet is the electromagnet of magnetic freeze mode, so after action was opened circuit in generation, described armature 511 can not regained the pushing tow state that is in, so can't close a floodgate from the external world always.
Have locked motor unit described in the primary cut-out of auto-lock function for the present invention and adopt the electromagnet 51 of common non-magnetic freeze mode, then also need to increase a secondary self-locking mechanism, it is a very important structure under this situation, because his existence, when making owing to the maintenance circuit, described primary cut-out is disconnected, simultaneously the secondary self-locking mechanism is started, described primary cut-out can not close at once when general personnel closed a floodgate, must be by release could realize the action of combined floodgate to the secondary self-locking mechanism, so improved fail safe.
