Background technology
At present, along with being widely used of various electronic products, and raising medical, the food service industry production environment, the application of dust proof workshop is also more and more.In other toilets of various level, because the modular construction of blower fan filtering unit (FFU) is convenient to old factory rehabilitation, system simple in structure is one of equipment that use amount is maximum in the toilet.Aerodynamic force as the FFU product provides parts, and can blower fan normally move is crucial.In a lot of clean rooms, the use amount of FFU is very many, and quantity is from tens to up to ten thousand, so we must understand the real time execution situation of motor through certain method.
Motor operational monitoring in the market has several method; One is to use thermistor to come the air-flow that the impeller of adorning produces on the perception motor, if motor stops operating, the temperature on the thermistor raises; Resistance change shows that motor shuts down to a certain degree the time.This method requires the environment temperature around the thermistor to keep certain scope, but the difference of environment temperature can produce corresponding influence to the motor running condition monitoring.Second method is to adopt photo-sensitive cell, and the reflecting piece of adorning is monitored the rotation of motor on the monitoring motor blade.But this requires fixing reflecting piece on each motor blade, and blade must be dark opaque.The cost of photosensitive head is also higher in addition, is not suitable for high volume applications.More than two kinds of methods all need the radiator fan that carries by motor, the perhaps impeller of band in addition.Be difficult to install for the place of flowing at impeller air, perhaps do not have the motor of impeller, then be difficult to monitoring.The third method, when motor stopped operating, the temperature detect switch (TDS) that motor internal carries can break off when motor temperature rises to certain value, thereby cut off electric current.Supervising device is through detecting the whether conducting of the double-end lead of this temperature detect switch (TDS), thereby judges whether motor is moving.Do not draw lead when the temperature detect switch (TDS) of motor internal, in the time of perhaps can't drawing lead, this method just can not be used.
Therefore, a kind ofly can not limited by environment temperature, monitoring system easy to detect and lower-cost be demanded urgently occurring.
The utility model content
Limited by environment temperature for solving existing various motor operational monitoring method; Or because the structural limitations of electronics self; Can't or detect problems such as cost is higher to its detection; The utility model discloses a kind of motor operating state supervisory system, not limited by environment temperature and motor self structure, monitor lower-cost purpose.
The technical scheme of the utility model is following:
A kind of motor operating state supervisory system comprises control panel, is arranged at the inductance element of detection power lead through current conditions on the said motor power-supply wire; Be electrically connected the control element that the electric signal of said inductance element is handled with said inductance element, and the signal that control element is handled is shown the display element of output; Said display element is the signal lamp that is arranged on the said control panel, also is provided with dry contact on the said control panel, and said dry contact is electrically connected with said control element.
Preferably, said signal lamp comprises power lights and trouble light.
Preferably, said supervisory system also comprises the warning device that is electrically connected with said control element.
Preferably, said warning device is audible-visual annunciator and/or buzzer siren.
The disclosed motor operating state supervisory system of the utility model; Through making power lead pass inductance element, inductance element detects power lead internal current situation, and whether dry contact moves according to motor and carry out break-make simultaneously; Control element is through being electrically connected respectively with inductance element and dry contact; Can monitor motor operation whether normally, this monitoring system is not limited by ambient temperature and motor self structure, and the monitoring cost is lower.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the disclosed a kind of motor operating state supervisory system of the utility model.
The title of the numeral among the figure or the corresponding component of alphabetical representative:
1, control panel 2, inductance element 3, power lights 4, trouble light 5, dry contact 6, power lead.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of motor operating state supervisory system, not limited by environment temperature and motor self structure, monitor lower-cost purpose.
As shown in Figure 1, a kind of motor operating state supervisory system comprises control panel 1, is arranged at the inductance element 2 of detection power lead through current conditions on the motor power-supply wire, and power lead passes inductance element 2; Be electrically connected the control element (not shown) that the electric signal of inductance element 2 is handled with inductance element 2, and the signal that control element is handled is shown the display element of output; Display element is the signal lamp that is arranged on the control panel 1, also is provided with dry contact 5 on the control panel, and dry contact 5 is electrically connected with control element.
Whether this motor operating state supervisory system has electric current to pass through through the power lead of monitoring motor, thereby judges whether motor is in running status.
Signal lamp comprises power lights 3 and trouble light 4, and when power lead inside had electric current to pass through, power lights 3 bright trouble lights 4 put out, and dry contact 5 is a closure state; When motor broke down, trouble light 4 was bright, and dry contact breaks off, and motor internal heats up gradually, and the temperature detect switch (TDS) of motor internal breaks off, and does not have electric current in the motor power-supply wire, and power lights 3 extinguishes.
