Abstract
The invention provides a radiator for a thyristor assembly of a converter valve. The radiator comprises radiator bodies, wherein a thyristor is arranged between every two adjacent radiator bodies; each radiator body comprises a shell body, the shell body is sequentially provided with an upper water nozzle, radiator shell body inner through holes for arranging damping resistors and a lower water nozzle from top to bottom, and further comprises a middle reserve zone positioned in the middle part of the shell body; the lower water nozzle of the Nth radiator body is communicated with the upper water nozzle of the N+2th radiator body through a pipeline, and N is greater than or equal to 1 and is an integer; the pipeline passes through the middle reserve zone of the N+1th radiator body; and the lower water nozzles of the rear-most two adjacent radiator bodies are communicated through a pipeline. The radiator reduces connectors of a cooling system, decreases the risk of leakage, improves operation reliability of the converter valve, does not need to disassemble the water pipes when overhauling the damping resistors, reduces overhaul difficulty of the thyristor assembly, and shortens the overhaul time.
Description
Technical field
The invention belongs to direct-current transmission converter valve field, particularly a kind of converter valve thyristor assembly radiating device.
Background technology
DC converter valve is the nucleus equipment of direct current transportation, converter valve is made up of multiple assembly usually, thyristor assembly, anode reactor is comprised in converter valve components, thyristor assembly also comprises thyristor, radiator, damping resistance, damping capacitor and the cooling system supporting with it, converter valve complex structure, part are various, can break down because of a variety of causes in running, fault needs the normal operation of carrying out in time overhauling to recover as early as possible converter valve after occurring, in the design process of converter valve, therefore need the convenience considering overhaul of the equipments in each link.
Current thyristor assembly internal damping resistance mainly contains two kinds of forms, the first: damping resistance is water resistance, damping resistance directly contacts with cooling water, independent heat radiation, with thyristor radiator and cooling water pipe non-interference, when cooling system normally runs, damping resistance can obtain good heat radiation, if but damping resistance is abnormal when needing maintenance, could starts service work after needing the cooling water in converter valve all to discharge, overhaul large, the consuming time length of difficulty; The second: damping resistance is excellent resistance, multiple excellent resistance is arranged in the through hole pre-set in thyristor radiator, damping resistance is dispelled the heat indirectly by thyristor radiator, decrease the joint in thyristor assembly, but there is the phenomenon of interfering in the cooling water pipe of the excellent resistance of part and thyristor radiator, maintenance and cooling water pipe have still to need the cooling water in converter valve all to discharge during the excellent resistance of interference after could dismantle cooling water pipe, overhaul difficult.
Summary of the invention
The object of this invention is to provide convenient, the efficient converter valve thyristor assembly radiating device of a kind of maintenance.
In order to reach above-mentioned purpose, solution of the present invention is: converter valve thyristor assembly radiating device, comprises radiator, for arranging thyristor between two adjacent radiators; Described radiator comprises housing, and described housing is provided with filling pipe end from top to bottom, successively for arranging the radiator casing inner via hole of damping resistance and the lower mouth of a river; Also comprise the trough, middle part being positioned at housing central section; The lower mouth of a river of described N number of radiator and the filling pipe end of N+2 radiator by pipeline communication, N >=1 and N is integer; Described pipeline passes from the trough, middle part of N+1 radiator; Pipeline communication is passed through between the lower mouth of a river of rearmost two adjacent radiators.
As further improved technical scheme of the present invention, described radiator casing inner via hole is at least two; Described radiator casing inner via hole is symmetrically distributed in the both sides of trough, middle part.
As further improved technical scheme of the present invention, the lower mouth of a river of described N number of radiator and the filling pipe end of N+2 radiator are by oblique pull cross current.
As further improved technical scheme of the present invention, by horizontal cross current between the lower mouth of a river of rearmost two adjacent radiators.
As further improved technical scheme of the present invention, by horizontal cross current between the lower mouth of a river of rearmost two adjacent radiators.
After adopting such scheme, the present invention has following beneficial effect:
1) damping resistance is arranged in thyristor radiator, reduces cooling system joint, reduces risk of leakage, improves converter valve operational reliability.
2) be arranged in damping resistance in thyristor radiator and radiator tube non-interference, do not need during overhaul damping resistance to dismantle water pipe, reduce the maintenance difficulty of thyristor assembly, reduce the repair time.
Accompanying drawing explanation
Fig. 1 is the structural representation of thyristor assembly radiator of the present invention.
Below in conjunction with the drawings and specific embodiments, the technical solution of the present invention is further elaborated.
