Abstract
The utility model discloses an alarm system for preventing secondary energy storage of a frame circuit breaker, comprising a main shaft, a handle, a first detecting element which can be triggered by the handle, a second detecting element which can be triggered by the main shaft, and a voice alarm. When the frame circuit breaker is in the closing state, the alarm system can give out a warning sound to remind that the manual energy storage operation can not be continued by a user if manual energy storage is used, thereby the burning loss of the circuit breaker can be avoided.
Description
Technical field
The utility model belongs to the breaker structure design field, especially a kind of warning device that prevents the frame circuit breaker secondary energy storage.
Background technology
Traditional frame-type circuit breaker, the shared same set of mechanism of their branch/switching-on mechanism and stored energy mechanism.When the contact of circuit breaker is when being in "on" position, if use manual energy storage, the situation that moving contact is slowly opened can take place, and generally be connected with hundreds of in the major loop of this moment even go up the electric current of kiloampere, along with slowly opening of moving contact will produce electric arc between dynamic and static contact, and this moment institute's electric arc that produces is owing to can not in time being extinguished, and because of the huge heat that electric arc produced is understood the scaling loss circuit breaker, thereby causes the generation of accident.The defective of such circuit breaker is that its branch/switching-on mechanism and stored energy mechanism are shared cover mechanisms, therefore on structure, are difficult to thoroughly avoid the generation of above-mentioned situation.
The utility model content
The purpose of this utility model provides a kind of when frame-type circuit breaker is in "on" position, if use manual energy storage, then sends the warning system that prevents the frame circuit breaker secondary energy storage of caution sound.
The technical scheme that realizes the utility model purpose is: a kind of warning system that prevents the frame circuit breaker secondary energy storage, comprise main shaft, handle, its design feature is: also comprise can by handle trigger first detecting element, second detecting element and the voice guard that can be triggered by main shaft.
Described handle is provided with the first triggering part that is used to trigger first detecting element, and described main shaft is provided with the second triggering part that is used to trigger second detecting element.
Described first detecting element and second detecting element are sensitive switches or near switch.
The utlity model has positive effect: the contact of (1) the utility model circuit breaker is when being in "on" position, if use manual energy storage, then when just pulling handle, first detecting element can be triggered by handle, second detecting element is also triggered by main shaft, pass through external control circuit, can remind the user can not proceed the operation of manual energy storage again, thereby can avoid circuit breaker generation burning damage accident by the voice guard sound that gives a warning.
Description of drawings
Fig. 1 is the structural representation of the utility model when being in gate-dividing state;
Fig. 2 is the structural representation of the warning device that prevents the frame circuit breaker secondary energy storage shown in Figure 1 when being in "on" position.
Be labeled as shown in the accompanying drawing: main shaft 1, handle 2, the first detecting elements 3, the second detecting elements 4.
Embodiment
(embodiment 1)
Fig. 1 to Fig. 2 has shown a kind of execution mode of the present utility model, and wherein Fig. 1 is the structural representation of the utility model when being in gate-dividing state; Fig. 2 is the structural representation of the warning device that prevents the frame circuit breaker secondary energy storage shown in Figure 1 when being in "on" position.
Present embodiment is a kind of warning system that prevents the frame circuit breaker secondary energy storage, comprise main shaft main shaft 1, handle 2, can by handle 2 trigger first detecting element 3, second detecting element 4 and the voice guard that can be triggered by main shaft 1.Described first detecting element 3 and second detecting element 4 are sensitive switches.
The course of work of present embodiment is as follows: when frame-type circuit breaker is under the gate-dividing state shown in Figure 1, this moment is if carry out closing by hand, in the closing by hand process, have only first detecting element 3 to be triggered by handle 2, second detecting element 4 can not be triggered by main shaft 1, this moment, voice guard did not send alarm sound under the control of external control circuit; When closing a floodgate fully, first detecting element 3 is triggered by handle 2, and second detecting element 4 is triggered by main shaft 1, and the two all is triggered, and this moment, voice guard did not send alarm sound yet under the control of external control circuit; When frame-type circuit breaker is under the "on" position shown in Figure 2, if carry out manual energy storage, 4 on handle can trigger first detecting element 3 once more, this moment is under the control of external control circuit, voice guard sends alarm sound, remind the user can not proceed the operation of manual energy storage again, thereby can avoid circuit breaker generation burning damage accident.
(embodiment 2)
Present embodiment is substantially the same manner as Example 1, and difference is: described handle 2 is provided with the first triggering part that is used to trigger first detecting element 3, and described main shaft 1 is provided with the second triggering part that is used to trigger second detecting element 4.In the present embodiment first triggers part and the second triggering part is the thrust that is separately positioned on handle 2 and the main shaft 1, but no matter the first triggering part and second triggers part is for which kind of concrete shape, and a needs can trigger first detecting element 3 exactly and second detecting element 4 gets final product.
Because the handle 2 in the frame-type circuit breaker and the position of main shaft 1 all are subjected to many-sided restriction, may make the installation of first detecting element 3 and second detecting element 4 also receive restriction, if trigger part so on handle 2, be provided for triggering first of first detecting element 3, be provided for triggering second of second detecting element 4 on the main shaft 1 and trigger part, then can make handle 2 and main shaft 1 trigger first detecting element 3 and second detecting element 4 more exactly, thereby make present embodiment have reliability and stability better.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection range of the present utility model.
