Abstract
The utility model discloses a contactor state inspection device which comprises control equipment, a relay and a contractor. The output of the control equipment is connected with the input of the relay. The relay is connected with the contactor. The contactor comprises a main contact and an auxiliary contact. The control equipment drives the relay. The relay makes the contactor coil obtain electricity. The main contact of the contactor is closed to make load obtain electricity and operate. In the meantime, the auxiliary contact obtains electricity and is closed. The auxiliary contact sends a feedback signal to the control equipment, and the control equipment receives the signal and judges whether the state of the contactor is normal. When the contactor is not closed due to some reasons, the auxiliary contact doesn't send a feedback signal and the control equipment doesn't receive the feedback signal, so as to judge a failure of the contactor. The utility model has beneficial effects as follows: the state of the contactor can be monitored at real time and the failure contactor can be immediately detected and found; a failure contactor can be immediately found when a plurality of contactors are used; and manpower and time are saved, and equipment safety is increased.
Description
Technical field
The utility model relates to a kind of high-voltage detecting device, relates in particular to a kind of contactor condition checkout gear.
Background technology
Contactor is a kind of high-tension apparatus commonly used in the transformer station, and state and the electric power safety of contactor are closely related.Up to the present, can only carry out control operation to contactor in the transformer station, the practical operation situation of contactor is not detected in real time, and the electric power personnel can't judge the ruuning situation of contactor, only just overhaul when contactor goes wrong; When contactor is more, it is that problem has appearred in which contactor that the electric power personnel can not judge immediately, take a long time maintenance, therefore, contactor is carried out state-detection can allow the electric power personnel grasp in real time the running status of contactor, in case contactor goes wrong and can judge very soon is that problem has appearred in which contactor, has saved manpower and time.
The utility model content
The purpose of this utility model is to provide a kind of contactor pick-up unit, this device can detect the real time execution situation of contactor, by sending feedback signal by contactor to opertaing device, judge whether contactor works, overcome the deficiency that to judge the contactor duty in the conventional art, thereby realized the purpose of this utility model.
The technical matters that the utility model solves can realize by the following technical solutions:
A kind of contactor condition checkout gear, comprise opertaing device, contactor and be arranged at opertaing device and contactor between relay, opertaing device is passed to relay coil with signal, relay drives contactor and makes the action of contactor main contacts, wherein, contactor also is provided with auxiliary contact, and auxiliary contact are connected with opertaing device, be used for sending feeding back signal to opertaing device, opertaing device judges according to feedback signal whether contactor works.
The beneficial effects of the utility model are:
Can carry out Real-Time Monitoring to the contactor state, can detect immediately and find the fault contactor, when using a plurality of contactor, can find out immediately the fault contactor, save manpower and time, increase the security of equipment.
Description of drawings
Fig. 1 is the schematic diagram of contactor condition checkout gear described in the utility model.
Fig. 2 is contactor condition checkout gear described in the utility model circuit diagram in the specific implementation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, contactor condition checkout gear described in the utility model comprises opertaing device 100, relay 200 and contact unit 300, relay 200 connects the output terminal of opertaing device 100, contact unit 300 connects relay 200, contact unit 300 comprises main contacts 320 and auxiliary contact 330, and the feedback signal 331 of auxiliary contact 330 outputs is connected with opertaing device 100; Opertaing device 100 output high level make the coil 210 of relay 200 get electric, relay contact 220 closures are so that contactor coil 310 gets electric, main contacts 320 closures of contactor, make load 400 get electric work, simultaneously auxiliary contact 330 also electric closure, auxiliary contact 330 send a feedback signal 331 to opertaing device 100, when opertaing device 100 is received feedback signal 331, judge that the contactor state is normal; When contact unit 300 because of coil do not have that electricity, voltage are low, when machinery reason stuck or contact adhesion is not moved, auxiliary contact 330 can't be closed, do not send feedback signal 331, opertaing device 100 is not received feedback signal 331, namely judges contact unit 300 faults.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (1)
1. contactor condition checkout gear, comprise opertaing device, contactor and be arranged at opertaing device and contactor between relay, opertaing device is passed to relay coil with signal, relay drives contactor and makes the action of contactor main contacts, it is characterized in that described contactor also is provided with auxiliary contact, auxiliary contact are connected with opertaing device, be used for sending feeding back signal to opertaing device, opertaing device judges according to feedback signal whether contactor works.
