Description
Technical field
The invention belongs to electric power low-pressure complete sets of electric switchgears and control devices apparatus field, the A.C. contactor that a kind of tape jam shows.
Background technology
Along with quickly propelling of China's economic technology, the infrastructure such as building construction, fire-fighting system has comprehensively development, and demand rises year by year.Low-voltage complete switch equipment play a part in low-voltage power supply and distribution system electric energy control, protect, measure conversion and distribution.Along with distribution technique, low-voltage component technology and the development of automatic technology, switchgear assembly also from traditional distribution to intelligent development, enter brand-new developing stage.
The A.C. contactor currently commonly used is usually opaque or transparency is bad, observation internal structure is inconvenient, after breaking down in contact, it is difficult to find trouble point by naked-eye observation, need to detect by equipment such as universal meters, maintenance inconvenience, makes repair time cost be greatly increased, is unfavorable for using manpower and material resources sparingly.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the A.C. contactor that a kind of tape jam shows.
The technical solution used in the present invention is:
The A.C. contactor that a kind of tape jam shows, including A.C. contactor body, controller, indicator lamp；The output of the main contacts of described A.C. contactor, auxiliary contact and contactor coil is connected respectively and is connected the input of controller after a protective resistance；The output of described controller connects indicator lamp；Described indicator lamp and the main contacts of A.C. contactor, auxiliary contact and contactor coil one_to_one corresponding；Described controller is also connected with a power supply；When contactor coil has pulse signal to input controller, and when contact does not has pulse signal input controller, the indicator lamp corresponding with this contact lighted by controller, breaks down in the contact of instruction correspondence；When contactor coil has pulse signal to input controller, and when also there is pulse signal input controller contact, the indicator lamp corresponding with this contact do not lighted by controller, and corresponding contact is working properly simultaneously.
Described controller is single-chip microcomputer.
Described indicator lamp is light emitting diode.
Described power supply is the end of incoming cables power supply of A.C. contactor 5V power supply after Transformer Rectifier is changed.
The present invention uses above technical scheme, utilizes the pulse signal that controller produces when gathering a contact power on/off, according to pulse signal, controller judges whether each contact breaks down, and according to judged result, controls whether indicator lamp indicates the fault of each contact.Present configuration is simple, and staff can judge the contact broken down intuitively, is greatly saved failure detection time, has saved manpower and materials.

Detailed description of the invention
The A.C. contactor that a kind of tape jam of the present invention shows as shown in Figure 1, including A.C. contactor body 1, controller 2, indicator lamp 3；
As in figure 2 it is shown, the internal circuit of A.C. contactor body 1 in the embodiment of the present invention, ac contactor coil is energized, and electromagnetic actuation drives the main contact linked therewith and auxiliary contact Guan Bi by spring；
As shown in Figures 3 and 4, the single-chip microcomputer as controller 2 connects has the normal necessary basic circuit that works, including crystal oscillating circuit and reset circuit；The main contacts of A.C. contactor, auxiliary contact and contactor coil output are connected respectively and are connected to the input of single-chip microcomputer after protective resistance R2 simultaneously；The output of single-chip microcomputer connects the multiple light emitting diodes as indicator lamp 3；
Described single-chip microcomputer is also associated with power circuit, as it is shown in figure 5, the power supply that the embodiment of the present invention uses is that contactor end of incoming cables power supply is passed through Transformer Rectifier circuit conversion for+5V power supply.
In the present embodiment, the surface-mounted integrated circuit with single chip machine controlling circuit being arranged on A.C. contactor side, when distribution box power supply is energized, contactor is energized, and single-chip microcomputer is also energized, and single-chip microcomputer enters duty.Contactor main contacts and auxiliary contact are connected with single-chip microcomputer composition button inputting circuits；Can form pulse signal and be sent to single-chip microcomputer during the work of contact, single-chip microcomputer combines the pulse signal of contactor coil and judges each contact whether fault.Single-chip microcomputer controls respectively further according to judged result and the lighting and extinguish of each contact light emitting diode one to one.
The concrete deterministic process of the present embodiment is as follows:
When distribution box power supply is energized, contactor is energized, and single-chip microcomputer is also energized, and single-chip microcomputer enters duty, extinguishes after Single-chip Controlling is all lighted three seconds as the light emitting diode of indicator lamp 3 simultaneously, to detect indicator lamp quality.Then single-chip microcomputer starts to detect the input signal of its input.
When contactor coil is connected and had pulse signal input single-chip microcomputer, contact coil does not has pulse signal to input, and single-chip microcomputer judges this contact fault, and single-chip microcomputer is lighted the light emitting diode corresponding with this contact and sent fault cues；When contactor coil is connected and had pulse signal input single-chip microcomputer, contact coil also has pulse signal to input, and single-chip microcomputer judges that this contact is working properly, and single-chip microcomputer keeps the OFF state of the light emitting diode corresponding with this contact.Whether staff can light according to respective leds quickly judges to break down in which contact, thus quickly keeps in repair the most accordingly, it is ensured that the normal work of equipment.
In sum, it is only the one of embodiments of the invention, not being used for limiting the scope that the present invention implements, all equalizations done according to the shape described in scope of the invention as claimed, structure, feature and spirit change and modify, all should be included in scope of the presently claimed invention.
