Background technology:
Valve base electronic device of direct current converter valve (being called for short VBE) is the interface equipment of control protection system and converter valve, is mainly used in triggering, supervision and the protection of finishing valve.When the control protection system issued the trigger command of valve, VBE was just according to this command triggers converter valve.In traditional design; to VBE, therefore, 12 valves need 12 optical fiber to finish the transmission of trigger command to the trigger command of each valve at least by an Optical Fiber Transmission; if whether the order of wanting verification VBE to receive is correct, then also need other 12 optical fiber with the anti-control protection system of sending back to of check information.This just needs 24 optical fiber to finish the transmission of trigger command, coffret mode complexity; And the control protection system trigger command signal that VBE needs special interface unit to receive usually distributes in inside, makes trigger command complicated in the transmission course of VBE inside, has increased design difficulty and R﹠D costs.
The utility model content:
The utility model purpose is to solve in the traditional design a little less than the antijamming capability, problems such as transmission course complexity, the valve base electronic device of direct current converter valve that a kind of logical antijamming capability is strong, communication interface is simple in structure, transmission contains much information is provided, reach the reduced data transmission course, improve the effect of efficiency of transmission.
For achieving the above object, the utility model provides a kind of valve base electronic device of direct current converter valve, this equipment comprises rack, power supply cabinet and light-operated cabinet, and described power supply cabinet and light-operated cabinet place in the rack, and its improvement is: adopt chain structure to connect between the described light-operated cabinet.
An optimal technical scheme of the present utility model is: the improvement of described a kind of valve base electronic device of direct current converter valve is, be provided with trigger command latch, thyristor junction temperature latch in the described light-operated cabinet, trigger code generator, return inspection coded buffer and valve condition handler, described trigger command latch is connected the triggering code generator with thyristor junction temperature latch, described time the inspection coded buffer connects the valve condition handler, and described triggering code generator is connected the gate pole electronic unit with time inspection coded buffer.
Of the present utility model one more preferably technical scheme be: the improvement of described a kind of valve base electronic device of direct current converter valve is, only needs 1 light-operated cabinet carry out transfer of data by 2 optical fiber and DC converter valve protection system in the described light-operated cabinet.
Of the present utility model another more preferably technical scheme be: the improvement of described a kind of valve base electronic device of direct current converter valve is that described light-operated cabinet can be provided with 12 at most.
Another optimal technical scheme of the present utility model is: the improvement of described a kind of valve base electronic device of direct current converter valve is that described power machine case comprises 6U power supply cabinet and 3U power supply cabinet.
The beneficial effects of the utility model: the utility model adopts trigger command coding and the thyristor junction temperature coding of chain structure in VBE internal transmission control protection system; omit special-purpose interface equipment between VBE and the control protection system, simplified the structure of communication interface.Reduced number of fibers, increased simple optical fiber information transmitted amount between control protection system and the VBE, improved data transmission efficiency, and had very strong antijamming capability.

Embodiment:
As shown in Figure 1, the utility model provides a kind of valve base electronic device of direct current converter valve, this equipment comprises rack 1, power supply cabinet and light-operated cabinet 3, power supply cabinet and light-operated cabinet 3 place in the rack 1, the power supply cabinet is used to a whole set of VBE equipment that work energy is provided, and it comprises 6U power supply cabinet 21 and 3U power supply cabinet 22.As shown in Figure 3, be provided with trigger command latch 31, thyristor junction temperature latch 32 in the light-operated cabinet 3, trigger code generator 33, return inspection coded buffer 34 and valve condition handler 35, trigger command latch 31 is connected triggering code generator 33 with thyristor junction temperature latch 32, return inspection coded buffer 34 and connect valve condition handler 35, trigger code generator 33 and be connected the gate pole electronic unit with time inspection coded buffer 35.As shown in Figure 4; the trigger command and the thyristor junction temperature that adopt chain structure transmission control protection system to assign between the light-operated cabinet 3; as long as this information that just makes the control protection system send is delivered to a photocontrol cabinet 3; just can be used by other light-operated cabinet 3 simultaneously, simplify trigger command and thyristor junction temperature transmission course in VBE inside.How much can changing of light-operated cabinet 3 numbers according to the size of thyristor valve scale, configurable 12 at most.Owing to adopt the asynchronous serial coding techniques; making only needs 1 light-operated cabinet 3 carry out transfer of data by 2 optical fiber and control protection system in the light-operated cabinet 3 of VBE; significantly reduce number of fibers, increased simple optical fiber information transmitted amount between control protection system and the VBE.
As Fig. 2, shown in Figure 3, the concrete course of work of VBE is as follows:
1) the control protection system sends trigger command and thyristor junction temperature to VBE; after VBE receives trigger command and junction temperature, produce the triggering coding that is sent to the gate pole electronic unit on the valve by the trigger command latch 31 in the light-operated cabinet 3, thyristor junction temperature latch 32 and triggering code generator 33.
2) in the light-operated cabinet 3 return inspection coded buffer 34 and valve condition handlers 35 are handled the inspection information of returning that the gate pole electronic units report, the whole monitor message of valve is returned to the control protection system.
Return inspection coded buffer 34 and receive time inspection coding that each gate pole unit reports, and deposit it in inner memory cell; Valve condition handler 35 reads back each memory cell of inspection coded buffer 34, adds up inspection information every time.If find that abnormal conditions appear in certain valve, then send the protectiveness trigger request to triggering code generator 33, require 33 pairs of these valves of triggering code generator to implement protectiveness and trigger, if necessary, send tripping operation to the control protection system and ask.In addition, valve condition handler 35 also gathers every information of valve the back and is sent to the control protection system by fieldbus.
Should be noted that at last; above embodiment is only in order to explanation the technical solution of the utility model but not it is limited; although the utility model is had been described in detail with reference to the foregoing description; described art is to be understood that: still can make amendment or be equal to replacement embodiment of the present utility model, and not break away from all should being encompassed in of the utility model spirit and scope claim protection range of the present utility model.
