Detailed description of the invention
The utility model is elaborated below in conjunction with the accompanying drawings and by specific embodiment, and following example are to explanation of the present utility model, and this utility model is not limited to implementation below.
If Fig. 1 is to shown in 2; a kind of frequency conversion motor of this utility model offer and the interlocking protection device of ventilation motor; including A.C. contactor, thermal overload relay and complement wiring terminal; the hook of described thermal overload relay is linked into A.C. contactor groove, and the conducting rod of described thermal overload relay inserts in A.C. contactor respective terminal;Described complement wiring terminal right-to-left is 1-6 binding post, described 1, No. 2 binding posts connect A1, A2 terminal of ac contactor coil respectively, described 3, No. 4 binding posts connect normally opened contact F98, F97 of thermal overload relay respectively, and described 5, No. 6 binding posts connect normally-closed contact F95, F96 of thermal overload relay respectively;Described 2, No. 5 binding posts pass through wire short circuit, frequency conversion multi-functional output contact B10 and No. 1 binding post of described frequency conversion motor connect, institute's frequency conversion multi-functional output contact B9 connects control power supply one end of ac contactor coil, and the other end A7 controlling power supply and No. 6 binding posts of described ac contactor coil connect;Normally opened contact F98, F97 of described thermal overload relay is connected with frequency conversion motor external fault contact point B3, B11 respectively.
In the present embodiment, three phase mains used by frequency conversion motor is accessed in the upside of described interlocking protection device.
In the present embodiment, the downside of described interlocking protection device connects the load line of ventilation motor.
In the present embodiment, described A.C. contactor and thermal overload relay are all supporting with ventilation motor.This utility model can apply to various model and specification frequency conversion motor, the control of ventilation motor and protection, can select, according to the power of ventilation motor, the control element matched therewith.
In the present embodiment, described binding post is all installed by screw fastening.
The control of ventilation motor realizes in the following way: ac contactor coil connects frequency conversion multi-functional output contact B9, B10(of thermal overload relay normally-closed contact F95, F96 and frequency conversion motor as a example by YD300 simultaneously), two terminations of its control line control power supply, and the voltage controlling power supply should be consistent with the mark voltage of coil.When the converter of frequency conversion motor puts into operation, frequency conversion multi-functional output contact B9, B10 are closed by normally opened contact, and the coil of the A.C. contactor action controlling ventilation motor obtains electric, and ac contactor coil adhesive, ventilation motor powers up operation.
The protection of frequency conversion motor is to be accomplished in that when ventilation motor breaks down; (its normally-closed contact F95, F96 disconnection that the appearance of its fault is necessarily caused by thermal overload relay action; causing ac contactor coil dead electricity, A.C. contactor disconnects, ventilation motor dead electricity).Thermal overload relay action also causes its normally opened contact F98, F97 to close simultaneously, the signal of its Guan Bi and converter external fault contact B3, B11(of frequency conversion motor are as a example by YD300) it is in parallel, i.e. creating fault-signal, the converter of frequency conversion motor stops because of fault-signal.
A kind of frequency conversion motor of this utility model offer and the interlocking protection device of ventilation motor; not only solve the control mode problem of frequency conversion motor ventilation motor; and the state of energy real-time tracking frequency conversion motor carries out on off control; consumption and the ventilation motor of saving the energy run the time; greatly reduce the fault rate of ventilation motor and frequency conversion motor, substantially prolongs the service life of equipment;When ventilation motor breaks down, its fault-signal produced causes the converter action of frequency conversion motor immediately, thus automatically disconnects frequency conversion motor, protects frequency conversion motor, greatly reduces the scope of fault, saves maintenance and the maintenance of cost of overhaul use, more conducively equipment.
The above; it it is only preferred embodiment of the present utility model; not this utility model is done any pro forma restriction, all within spirit of the present utility model and principle, is made any amendment, equivalent and improvement etc., within should be included in protection domain of the present utility model.
