Abstract
The utility model relates to an emergency protective circuit device responding to over current, an alarm-type residual-current circuit breaker, especially relates to an alarm-type residual-current circuit breaker. The alarm type residual current circuit breaker includes a residual-current circuit breaker body, and a buzzer connected with the residual-current circuit breaker body. The alarm-type residual-current circuit breaker is characterized in that the residual-current circuit breaker body is also provided with a reset indicator light, and a reset switch used for selectively switching the operation of the buzzer and the reset indicator light. The alarm-type residual-current circuit breaker of the utility model is advantageous in that through setting the reset switch on the residual-current circuit breaker body, it is convenient for a user to press the reset switch in a period of handling an electric leakage accident, such that the reset indicator light can replace the buzzer to perform electric leakage indication, and therefore, sound and light alarm integration can be realized, and unnecessary noise pollution can be reduced.
Description
Technical field
The utility model relates to the emergency protection circuit device for electric to the overcurrent response, relates in particular to a kind of alarm type residual current circuit breaker.
Background technology
According to the latest edition standard GB/T 13955-2005 of the People's Republic of China (PRC) " aftercurrent action protecting equipment installation and operation " 4.6 clause regulations: " in case when the residual current overrate occuring cutting off the electricity supply; because of electric device and the place that power failure causes heavy economic losses and bad social influence, the alarm type Aftercurrent protecting equipment should be installed.As: a) emergency power supply of public place, pathway lighting; B) guarantee the equipment of public place safety; C) power supply of fire-fighting equipment is such as Fire lift, fire pump, fire fighting passageway illumination etc.; D) power supply of burglar alarm; D) other do not allow the special installation and the place that have a power failure ".
But, the present domestic professional factory that does not also produce this series products, this standard issue is existing more than 2 years, is not generally implemented yet.Although some dealers have developed the short-circuit protection system with warning function, mostly be directly to connect a buzzer in residual current circuit breaker.This directly residual current circuit breaker install buzzer structure so that: exceed standard in case leakage current occurs, buzzer will ring always and not stop, until the leak current fault eliminating; Noise pollution is serious.
Summary of the invention
For problems of the prior art, the purpose of this utility model is to develop a kind of band sound and light alarm and organically combines, the convenient alarm type residual current circuit breaker of switching.
For reaching above purpose, the utility model adopts following technical scheme.
The alarm type residual current circuit breaker, comprise: the residual current circuit breaker body, be connected buzzer with the residual current circuit breaker body, it is characterized in that, also be provided with homing light on the described residual current circuit breaker body, and be used for selecting to switch the reset switch of buzzer and homing light work.
As with improvement, also be provided with at least one normally opened contact and at least one normally-closed contact on the described residual current circuit breaker body.
As with improvement, described residual current circuit breaker body is provided with binding post, and described buzzer is connected with binding post by wire, and the length of this wire is less than or equal to 100 meters.
Compare with existing residual current circuit breaker, the beneficial effects of the utility model are: by at the residual current circuit breaker body reset switch being set, make things convenient for the user during processing leak current fault, press reset switch and replace the buzzer indication of leaking electricity with homing light, the realization sound and light alarm is integrated, reduces unnecessary noise pollution.
Description of drawings
Figure 1 shows that the alarm type residual current circuit breaker structured flowchart that the utility model provides;
Figure 2 shows that the alarm type residual current circuit breaker structural representation that the utility model provides.
Description of reference numerals:
1, residual current circuit breaker body 2, handle 3, buzzer 4, reset switch 5, homing light.
Embodiment
For further setting forth essence of the present utility model, by reference to the accompanying drawings embodiment of the present utility model is described as follows.
Such as Fig. 1, shown in Figure 2, the alarm type residual current circuit breaker that present embodiment provides comprises: residual current circuit breaker body 1, be arranged on the handle 2 on the residual current circuit breaker body, and be connected buzzer 3 with residual current circuit breaker body 1, it is characterized in that, also be provided with homing light 5 on the described residual current circuit breaker body 1, and be used for selecting to switch the reset switch 4 of buzzer 3 and homing light 5 work.
Wherein, described buzzer 3 is installed on the residual current circuit breaker body 1, and described reset switch 4 is with auto-lock function, namely press reset switch 4 after, the prompting of leaking electricity of buzzer 3 stop alarms, homing light 5.In other execution modes, described residual current circuit breaker body is provided with binding post, and buzzer is connected with binding post by wire, and the length of this wire is no more than 100 meters.
Further, for ensureing Electrical Safety, also be provided with at least one normally opened contact and at least one normally-closed contact on the described residual current circuit breaker body 1, make things convenient for the user to select according to actual conditions.
A kind of alarm type residual current circuit breaker that present embodiment provides by at the residual current circuit breaker body buzzer being set, is sent alarm sound immediately in case the generation leakage current exceeds standard, and prompting user is processed.Especially, by at the residual current circuit breaker body reset switch being set, make things convenient for the user during processing leak current fault, press reset switch and replace the buzzer indication of leaking electricity with homing light, the realization sound and light alarm is integrated, reduces unnecessary noise pollution.
Above embodiment has been described in detail essence of the present utility model, but can not come protection range of the present utility model is limited with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that these improvement and modification all drop within the claim protection range of the present utility model.
