Abstract
The utility model discloses an unusual alarm device of electromagnetic contactor for system control heats, including electromagnetic contactor, with the auxiliary relay that electromagnetic contactor links to each other, link to each other with auxiliary relay OUT the contact, locate auxiliary relay and OUT auxiliary relay normally open contact between the contact, electromagnetic contactor, auxiliary relay, OUT contact, auxiliary relay normally open contact form the first loop, auxiliary relay normally open contact's one end is connected with auxiliary relay normally closed contact, auxiliary relay normally closed contact's the other end links respectively has supplementary normally open contact of electromagnetic contactor and siren, the other end and the electromagnetic contactor of siren link to each other, electromagnetic contactor, auxiliary relay normally open contact, auxiliary relay normally closed contact, the supplementary normally open contact of electromagnetic contactor and siren formation second return circuit. The utility model discloses a heating, the unusual work of electromagnetic contactor provides an alarm device for the system control, can guarantee heating system safety, the steady operation.
Description
Technical field
The utility model relates to a kind of abnormality alarm device, especially relates to a kind of heating system control electromagnetic contactor abnormality alarm device.
Background technology
At present, for heating system control apparatus many employings electromagnetic contactor, because its use cost is lower, and easily change.But in its use procedure, there is no real-time abnormality alarm device, user of service need be relied on to make regular check on.This kind of drawback likely can cause abnormal heating, there is hidden danger, and significant problem likely can be caused to occur.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is, provides a kind of heating system control electromagnetic contactor abnormality alarm device, changes and needs at present to rely on user of service to make the present situation made regular check on.
The technical solution of the utility model is: heating system control electromagnetic contactor abnormality alarm device, it is characterized in that: comprise electromagnetic contactor, the auxiliary reclay be connected with described electromagnetic contactor, the TC be connected with auxiliary reclay OUT contact, be located at described auxiliary reclay and TC auxiliary reclay normally opened contact between OUT contact, described electromagnetic contactor, auxiliary reclay, TC OUT contact, auxiliary reclay normally opened contact form the first loop; One end of described auxiliary reclay normally opened contact is connected with auxiliary reclay normally closed contact, the other end of described auxiliary reclay normally closed contact is connected with electromagnetic contactor respectively and assists normally opened contact and warning horn, the other end of described warning horn is connected with electromagnetic contactor, and described electromagnetic contactor, auxiliary reclay normally opened contact, auxiliary reclay normally closed contact, electromagnetic contactor assist normally opened contact and warning horn to form second servo loop.
The beneficial effect that the utility model reaches: for heating system control electromagnetic contactor abnormal work provides a kind of alarm device, heating system safety can be ensured, stable operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, heating system controls with electromagnetic contactor abnormality alarm device, comprise electromagnetic contactor 1, the auxiliary reclay 2 be connected with described electromagnetic contactor 1, the TC be connected with auxiliary reclay 2 OUT contact 3, be located at described auxiliary reclay 2 and TC auxiliary reclay normally opened contact 4 between OUT contact 3, described electromagnetic contactor 1, auxiliary reclay 2, TC OUT contact 3, auxiliary reclay normally opened contact 4 form the first loop; One end of described auxiliary reclay normally opened contact 4 is connected with auxiliary reclay normally closed contact 5, the other end of described auxiliary reclay normally closed contact 5 is connected with electromagnetic contactor respectively and assists normally opened contact 6 and warning horn 7, the other end of described alarm 7 device is connected with electromagnetic contactor 1, and described electromagnetic contactor 1, auxiliary reclay normally opened contact 4, auxiliary reclay normally closed contact 5, electromagnetic contactor assist normally opened contact 6 and warning horn 7 to form second servo loop.
First loop is provided with auxiliary reclay 2, and when needs heat, auxiliary reclay 2 obtains electric, its normally opened contact 4 conducting, and normally closed contact 5 disconnects, and electromagnetic contactor is started working; After the normally closed contact 5 of auxiliary reclay, be in series with the auxiliary normally opened contact 6 of electromagnetic contactor, control the action of warning horn 7.When heating signal does not exist, the normally closed contact 5 of auxiliary reclay is in conducting state, and it is often driven auxiliary contact 6 and is in conducting state when electromagnetic contactor abnormal work, and in such cases, warning horn exports and reports to the police.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
