In the failure output circuit Connection Time relay of the primary transducer and standby variable frequency device, described time relay The reset terminal of double-throw switch described in device timing closing contact portion.
Described standby variable frequency device is provided with control knob and ammeter.
A kind of mutual standby control circuit of industrial furnace blower fan dual power supply converter of the present utility model, which is by dual-power transfer switch Converter mutually standby control circuit is applied to, mutually standby handover operation is simple for converter, and double-throw switch has electric interlock and mechanical interlocking, There is reliable electric interlock in loop, be not in maloperation, handover security reliability can put into standby variable frequency at short notice Device;The time delay reset of double-throw switch and time-delay conversion, it is ensured that switch extends switch without load switching and conversion times Service life;When automatic conversion goes wrong, switch can be got to manual operation;Convenient megameter trial inspection is measured Electrical machine insulation is time saving and energy saving.
The beneficial effect brought of technical scheme that this utility model is provided is:
1st, mutually standby control switching circuit is simple to operate for converter, can reduce equipment down time, it is to avoid cause system shutdown With big economic loss;
2nd, convenient megameter trial inspection measurement motor insulate, time saving and energy saving.
3rd, parking maintenance, maintainer is facilitated just to occur within 15 minutes in failure after possible motor reason is excluded Standby variable frequency device has been put into, if 1-2 hour or longer time are needed if converter is changed, ensure that system well The safe and stable operation of device.

Specific embodiment
It is to make the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing Type embodiment is described in further detail.
Embodiment one
The present embodiment is the control circuit under purely mechanic double-throw permutator state.
As shown in Figure 1, major loop:Choose suitable manual three double-throw switch QS, in primary transducer cabinet after Face, is continuously connected using flexible cord with converter.Control loop:Primary transducer U keeps original control mode constant;Standby variable frequency device UII carries out panel operation start and stop motor;The given 4-20ma signals of standby variable frequency device frequency also use double-throw knife switch control, are leading Control signal double-throw knife switch is above installed in frequency-charger cabinet and connects holding wire.Such as Fig. 2.When power failure or primary transducer failure When needing maintenance, standby variable frequency device can be put into manually.
Embodiment two
As shown in figs. 3-7, using PC levels ATSE, mutually standby formula is automatically controlled the present embodiment double-throw switch.
The selection of double-throw switch:Using PC level ATSE automatic change-overs, 3 poles, use classes select AC-33B infrequently to grasp Make motor type.Major function:Automatic/hand conversion, with " I " " 0 " " II " three settling positions, switching time preferably may be used Adjust, switch condition such as overvoltage parameter and under-voltage parameter can be as far as possible loose, it is not necessary to excessive defencive function, and electric current is according to certainly Bear load, it is not necessary to haul oneself willingly into runback function.Select the product through CQC certifications, ATSE controllers test by EMC, no Can be in misoperation under external electromagnetic interference.
Compared with embodiment one, the major loop mode of connection is constant, and control loop is changed on the basis of original loop.
Double-throw switch control power supply is coupled with converter upper end;Double-throw switch auxiliary is sealed in converter starting-up later time Point, it is therefore an objective to could start converter after input load, prevents double end switch on-load switching;Active and standby converter starts relay Device adds interlocking;Active and standby frequency converter failure output connects the time relay, and time relay timing closing contact connects double-throw switch and puts " 0 " terminal;Other wiring of double-throw switch are completed according to switching declaration book;The 4-20ma signals master control of two converters point Do not send;Standby variable frequency device adds control knob, ammeter, double-throw switch to have position instruction etc. in master control in master control, as desired Fixed, other control wiring can increase and decrease as needed.
