The utility model has the advantages that, in device for under-voltage releasing equipment, set up a sensitive switch, when its device for under-voltage releasing equipment is threaded off, one index signal is provided, the separating brake of the circuit breaker that makes the user in time learn under-voltage fault and cause, the faults such as dropout of device for under-voltage releasing equipment, to facilitate the user can carry out quickly analytical review and maintenance, thereby avoid loss to increase.
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and coordinate appended accompanying drawing to be described in detail below.
The accompanying drawing explanation
The schematic diagram that Fig. 1 is device for under-voltage releasing equipment of the present utility model under trip status not;
Fig. 2 is the schematic diagram of device for under-voltage releasing equipment of the present utility model under trip status;
Fig. 3 is that sensitive switch of the present utility model is arranged at the outer schematic diagram of device for under-voltage releasing equipment.
Embodiment
Please refer to Fig. 1,2, the utility model discloses a kind of device for under-voltage releasing equipment 1, is the control unit of a circuit breaker, when the system line internal cause fault at this device for under-voltage releasing equipment 1 place and when under-voltage, this device for under-voltage releasing equipment 1 is threaded off and makes breaker open operation.Wherein this device for under-voltage releasing equipment 1 comprises: sensitive switch 11 is positioned at the position that can link with this device for under-voltage releasing equipment 1 dropout action, to show the under-voltage condition of this system line.
This device for under-voltage releasing equipment 1 also comprises: carriage release lever 121, can between a dropout position (see figure 2) and a make position (see figure 1), move, during for dropout or closure, also control the switch motion of this sensitive switch 11, this sensitive switch 11 is fixed in the housing of this device for under-voltage releasing equipment 1, be positioned at the top end of this carriage release lever 121, for by this carriage release lever 121, being touched.This sensitive switch 11 also comprises: contact 111, while for this device for under-voltage releasing equipment 1, threading off, by this carriage release lever 121, do not touched.This sensitive switch 11 also comprises: indicating device 112 is electrically connected to this contact 111.This indicating device 112 is indicator light or/and buzzer, and wherein this indicator light is arranged at outside this device for under-voltage releasing equipment 1.
The utility model can be set up a sensitive switch 11(such as Fig. 1,2 on the basis of existing device for under-voltage releasing equipment).Existing device for under-voltage releasing equipment 1 mainly comprises: undervoltage trip coil 122, spring 123, mobile armature 124 and carriage release lever 121.This sensitive switch 11 of setting up comprises the electric loop that consists of contact 111, indicating device 112 etc.This indicating device 112 can be indicator light, and this indicator light is arranged at the outside of device for under-voltage releasing equipment 1, even extends Anywhere far, and namely the user can see and getting final product; This indicating device 112 can be also buzzer, is arranged at the position that the user is heard and gets final product.
when the system line at place is in normally (not under-voltage) state, this undervoltage trip coil 122 has electric current to flow through and produces electromagnetic force, with this mobile armature 124 of adhesive, and make this carriage release lever 121 be in a make position (see figure 1), at this moment spring 123 is compressive state and has a precompression, meanwhile, this carriage release lever 121 is under the effect of mobile armature 124 adhesives, the top of this carriage release lever 121 is resisted against these contact 111 places of this microswitch 11, at this moment, electric loop in this sensitive switch 11 is off-state, therefore this indicating device 112 electricity is connected and without demonstration.
when this system line breaks down while being in improper (under-voltage) state, these undervoltage trip coil 122 no currents are flowed through, the electromagnetic force that produces disappears, at this moment this mobile armature 124 is no longer by adhesive, this spring 123 discharges precompression, and this mobile armature 124 is moved, this carriage release lever 121 can move to a folding position (see figure 2) along with this movable moving of part 124 of rank, at this moment this contact 111 of this microswitch 11 is not touched on the top of this carriage release lever 121, and make the electric loop in this sensitive switch 11 become closure state, therefore these indicating device 112 electricity are connected and show or buzzing, realize thus the prompting of under-voltage fault.
As can be seen from the above, when the utility model breaks down at system line, can, by this microswitch 11 is touched and shows faulty indication when device for under-voltage releasing equipment is threaded off, in time inform thus the under-voltage fault of user.
In another embodiment, please refer to Fig. 3, this sensitive switch 11 also can be fixed in outside the housing of this device for under-voltage releasing equipment 1, and the top of this carriage release lever 121 is extended outside this housing, equally, the top of this carriage release lever 121 is for controlling this sensitive switch 11 actions, and its operation principle is with an above-mentioned embodiment.
In addition, this sensitive switch can be selected the plunger piston type sensitive switch, is snapped on this device for under-voltage releasing equipment 1; Can also by the fastening means of fixture such as a plurality of screws, this sensitive switch 11 be fixed on this device for under-voltage releasing equipment 1.
