Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is a kind of a kind of converter inclining brake that specific implementation mode is provided control electricity of the present invention
The schematic diagram on road.
In a kind of specific implementation mode of the present invention, the embodiment of the present invention provides a kind of converter inclining brake control electricity
Road, including：The N number of switch being series in control circuit, wherein the N is the positive integer more than 1.It specifically, in the figure can be with
See there is N number of switch, the 1st switch 101, the series connection of the 2nd switch 102 ... N switches 103 are integrally formed converter inclining brake
Control circuit.The embodiment of the present invention is by the way of multiple switch of connecting, when being carried out to converter inclining device, if therein
One switch breaks down, and others switch remains able to control converter inclining brake, to avoid the hair of accident
It is raw, it can incline to avoid because the no normal reset of switch causes converter to continue to run with when carrying out shut-down operation to transcription
Tiltedly to 130 ° of angles.
For example, when N is equal to 2, then N number of switch is：First switch, second switch.If the event of a switch
Barrier rate is a ten thousandth, then two switch simultaneous faults can just cause converter inclining failure, and two switch simultaneous faults
Probability be hundred million points to one, greatly reduce converter accidents generation probability.Certainly, which is specifically being set, the
Two switches are, can be by the first switch, the second switch linked switch each other；The first switch, described second open
Guan Tongkai, it is arranged with pass.That is, in the concrete operations first switch and the second switch, the first switch, second are needed
Double-point double-throw switch specifically may be used with opening with closing in switch, while being opened and closed two switches.
Referring to FIG. 2, a kind of converter inclining brake control that Fig. 2 is provided for another specific implementation mode of the invention
The contactor schematic circuit diagram of circuit；Fig. 3 is that the secondary circuit of contactor shown in Fig. 2 controls the schematic circuit diagram of signal.
On the basis of above-mentioned specific implementation mode, the present embodiment further, using two switch in the case of,
Converter inclining brake control circuit, can be first contactor 201 by the first switch, and the second switch connects for second
Tentaculum 202.Whether there is or not to attract moving magnet core ribbon to move primary circuit by the magnetic force of secondary circuit control electromagnetic coil for contactor
Whether electrical contact is connected, primary circuit is controlled, can quickly cut off exchange and direct current major loop and can be frequently switched on and big electricity
The device of flow control (reaching 800A) circuit is done in order to control so often applying to motor to being set as ﹐ also is used as control factory
It can not only be switched on and off circuit for electrical loads, contactors such as the hot device ﹑ machine-tools of ﹑ electricity and various kinds electric power units, but also
With low-voltage release guard effect.Contactor control capability is big, is suitable for frequent operation and far distance controlled, is to automatically control
One of critical elements in system.
After first contactor 201, second contactor 202 are connected, to first fascinating circuit brake in circuit in parallel
203, second circuit brake 204, the third circuit brake the 205, the 4th that fascinates that fascinates fascinates the main circuit of circuit brake 206
Energization whether controlled, and then control converter and fascinate.
It is possible to further which the control signal of the control signal of the first contactor, the second contactor is arranged
It, in this way can be by first contactor second contactor synchronous control for same control signal.Two controls can certainly be used
Signal controls first contactor second contactor respectively, at this moment then needs to carry out first contactor, second contactor respectively
Control, needs to operate twice.
It please refers to Fig.4, Fig. 5, Fig. 4 is a kind of contactor signal electricity of converter inclining brake control circuit in the prior art
Lu Tu；Fig. 5 is that the secondary circuit of contactor shown in Fig. 4 controls the schematic circuit diagram of signal.
The cooperation control signal 501 of contactor 401 is used to carry out the control of converter inclining in the prior art, and the present invention is implemented
Mode is compared with technical solution in the prior art, and the embodiment of the present invention is by the way of multiple switch of connecting, when to converter
When the device that fascinates carries out, if one of switch breaks down, others switch remain able to converter inclining brake into
Row control can be when carrying out shut-down operation to avoid the generation of accident to transcription, can be to avoid because switching abnormal
Reset causes converter to continue to run with and tilts to 130 ° of angles.
It is of course also possible to the N is set as 3 in converter inclining brake control circuit, then N number of switch is：
First switch, second switch, third switch.Specifically, the first switch, the second switch, the third can be opened
Close the contactor of signal parallel connection in order to control.It is of course also possible to which the first switch, the second switch, the third are switched
It is set as opening, with the mechanical switch closed to be same, such as the mechanical switch that three knives three are thrown.
Can be the identical switch of model specification by the switch on the basis of above-mentioned specific implementation mode.For example, such as
Fruit converter inclining brake control circuit using contactor series control mode, then can be by the type of all contactors
Number it is set as identical.
In a kind of specific implementation mode of the present invention, the present embodiment provides a kind of converter inclining brakes, are equipped with above-mentioned
Any converter inclining brake control circuit.
Finally, it is to be noted that, herein, relational terms such as first and second and the like be used merely to by
One entity or operation are distinguished with another entity or operation, without necessarily requiring or implying these entities or operation
Between there are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant meaning
Covering non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only that
A little elements, but also include other elements that are not explicitly listed, or further include for this process, method, article or
The intrinsic element of equipment.In the absence of more restrictions, the element limited by sentence "including a ...", is not arranged
Except there is also other identical elements in the process, method, article or apparatus that includes the element.
