Description
Technical field
This invention relates generally to a kind of electrical apparatus release of breaker, in particular to a kind of electrical apparatus release with overload-alarm function.
Background technology
Breaker is the common components of electric field, for connection and breaking current, and provides protection to circuit in the case of overload or short circuit.Breaker generally has electrical apparatus release, disconnect breaker.
Fig. 1 show the schematic diagram of existing electrical apparatus release, and the electrical apparatus release includes housing 1, switching switch 2, bimetal piece 3, trace 4 and armature 5.Under normal condition, switching switch 2 is connected with the trigger unit 6 on trace 4, and trace 4 is maintained at the position by the spring of inside so that loop keeps connection.When overload situations occur, bimetal piece 3 temperature distortion corresponding with overload loop, and promote the contact site 7 on trace 4; so that trace 4 rotates, by one section of deformation time, the trigger unit 6 and switching switch 2 for forcing trace 4 depart from; so as to cut-off loop, overload protective function is played.When short-circuit conditions occur for any one loop in loop or more than one loop, the armature 5 corresponding with the loop of short circuit rotates, and promotes trace 4 so that the trigger unit 6 of trace 4 departs from switching switch 2, so as to cut-off loop.
That is, when overload or short-circuit conditions occur, existing electrical apparatus release is the direct cut-off loop in the case where confirming without staff.However, in some cases, when occurring to overload phenomenon, adverse effect can be brought by directly sudden shutting off loop, for example, in special occasions and the Important building such as fire-fighting power supply and medical treatment power supply, automatic cut-off loop can result in greater loss after there is overload.
Therefore, it is necessary to a kind of electrical apparatus release and breaker of more hommization so that when occurring to overload phenomenon, judgement that can be artificial and cut-off loop is chosen whether, to avoid causing heavy losses as far as possible.
Above- mentioned information is only used for strengthening the understanding of the background to the present invention disclosed in the background section, therefore it can include not forming the information to prior art known to persons of ordinary skill in the art.
The content of the invention
A primary object of the present invention is at least one defect for overcoming above-mentioned prior art, there is provided a kind of electrical apparatus release and breaker so that when occurring to overload phenomenon, judgement that can be artificial and cut-off loop is chosen whether, to avoid causing heavy losses as far as possible.
For achieving the above object, the present invention adopts the following technical scheme that:
According to an aspect of the present invention; provide a kind of overload-alarm electrical apparatus release; for being overloaded to loop and short-circuit protection, it includes housing, switching switch, at least one overload trigger unit, at least one short-circuit trigger unit, the first trace, the second trace and overload alarming mechanism.
Switching switch is mobilizable to be arranged on housing.At least one overload trigger unit is located in housing, and corresponding with loop.At least one short-circuit trigger unit is located in housing, and corresponding with loop.First trace is rotatably arranged on housing, and the first trace has first body of rod and the first trigger unit on first body of rod and at least one first contact site, and the first contact site is correspondingly arranged with overload trigger unit.Second trace is rotatably arranged on housing, and second trigger unit and at least one second contact site, second contact site of second trace with second body of rod and on second body of rod are correspondingly arranged with short-circuit trigger unit.Overload alarming mechanism is located in the rotating range of the first trigger unit.
Wherein, when overloading or being short-circuit do not occur in each loop, switching switch contacts with the second trigger unit, and each loop is in the conduction state.
When any loop is overloaded, overload trigger unit corresponding to the loop overloaded promotes the first corresponding contact site, so that the first trace rotates relative to housing, in the first trace rotary course, first trigger unit triggers overload alarming mechanism, it is set to send overload signal, switching switch keeps contacting with the second trigger unit, and each loop is still in conducting state.
When any loop occurs short-circuit, the short-circuit trigger unit rotation corresponding to the loop of short circuit occurs, and promotes the second corresponding contact site, drives the second trace to be rotated relative to housing so that the second trigger unit separates with switching switch, so as to which each loop is cut off.
According to another aspect of the present invention, there is provided a kind of breaker, it includes above-mentioned overload-alarm electrical apparatus release.
The advantageous effects of the present invention are:When any loop is overloaded, overload-alarm electrical apparatus release of the invention sends overload signal in the case where keeping the conducting of each loop, and staff, which receives the report for police service, can judge after signal according to actual conditions and choose whether cut-off loop.For example, in special occasions and the Important building such as fire-fighting power supply and medical treatment power supply, other emergency modes in addition to cut-off loop can be used.Compared to existing electrical apparatus release, overload-alarm electrical apparatus release of the invention is not the automatic cut-off loop after occurring overloading, and is to provide staff and judges and select, so as to avoid thus heavy losses directly caused by open circuit.
