Description
Technical field
The invention belongs to direct-current transmission converter valve field, more particularly to a kind of converter valve thyristor assembly radiating device.
Background technology
DC converter valve is the nucleus equipment of direct current transportation, and converter valve is generally made up of multiple components, in converter valve components
Including IGCT component, anode reactor, IGCT component also include IGCT, radiator, damping resistance, damping capacitor and
The cooling system supporting with it, converter valve is complicated, part is various, can be broken down in the process of running because of a variety of causes,
Failure needs to be overhauled in time to recover the normal operation of converter valve as early as possible after occurring, therefore is needed in the design process of converter valve
The convenience of overhaul of the equipments is considered in each link.
IGCT component internal damping resistance mainly has two kinds of forms at present, the first：Damping resistance is water resistance, damping electricity
Resistance is directly contacted with cooling water, and independent radiating, non-interference with thyristor radiator and its cooling water pipe, cooling system is normally transported
During row, damping resistance can obtain good radiating, if but damping resistance need extremely maintenance when, it is necessary to will be cold in converter valve
But water could start service work after all discharging, and maintenance difficulty is big, time-consuming；Second：Damping resistance is rod resistance, multiple
Rod resistance is arranged in the through hole pre-set in thyristor radiator, and damping resistance is radiated indirectly by thyristor radiator,
Reduce the joint in IGCT component, but the phenomenon of interference be present in the cooling water pipe of part rod resistance and thyristor radiator,
Maintenance still needs to when having the rod resistance of interference with cooling water pipe could to dismantle after the cooling water in converter valve is all discharged cold
But water pipe, maintenance are difficult.
The content of the invention
It is an object of the invention to provide one kind to overhaul convenient, efficient converter valve thyristor assembly radiating device.
In order to reach above-mentioned purpose, solution of the invention is：Converter valve thyristor assembly radiating device, including radiating
Device, it is used between adjacent two radiators set IGCT；The radiator includes housing, and the housing is from top to bottom successively
Radiator casing inner via hole and collector nozzle provided with filling pipe end, for setting damping resistance；Also include being located in housing central section
Portion trough；The collector nozzle of the n-th radiator and the filling pipe end of the N+2 radiator pass through pipeline communication, N >=1 and N
For integer；The pipeline passes through from the middle part trough of the N+1 radiator；The lower water of rearmost two adjacent radiators
Pass through pipeline communication between mouthful.
As further improved technical scheme of the present invention, the radiator casing inner via hole at least two；It is described to dissipate
Hot device housing inner via hole is symmetrically distributed in the both sides of middle part trough.
As further improved technical scheme of the present invention, the collector nozzle and the N+2 radiator of the n-th radiator
Filling pipe end connected by oblique pull water pipe.
As further improved technical scheme of the present invention, lead between the collector nozzle of rearmost two adjacent radiators
Cross horizontal water pipe connection.
As further improved technical scheme of the present invention, lead between the collector nozzle of rearmost two adjacent radiators
Cross horizontal water pipe connection.
After such scheme, the invention has the advantages that：
1) damping resistance is arranged in thyristor radiator, reduces cooling system joint, reduces risk of leakage, improves the change of current
Valve operational reliability.
2) damping resistance and radiator tube being arranged in thyristor radiator are non-interference, during overhaul damping resistance not
Water pipe need to be dismantled, the maintenance difficulty of IGCT component is reduced, reduces the repair time.
