Description
Technical field
The utility model relates to electric power system inversion transformation technique field, particularly a kind of in train, shock resistance and the good water-cooled anode reactor of insulating properties.
Background technology
In high pressure, high-power converter, the electric current rate of climb (di/dt) and higher surge current when anode reactor is mainly in order to suppress power device (as IGCT) to be opened, next suppresses power device blocking interval circuit to occur higher voltage build-up rate (dv/dt), the surge voltage of bearing to avoid Thyristor and opening by mistake of causing is logical.
At present, such reactor major part is the external ABB of import, Siemens, GE import or its Counterfeit Item.The Chinese patent being CN101013623A as publication number discloses a kind of water-cooled reactor for converting of integrated gate commutated thyristor, the coil of this reactor is hollow copper tube, it is all circular that hollow copper tube is processed into each circle, and helical ring is coiled into the reactor of a toroidal; Two ports of hollow copper tube are welded with water inlet and delivery port respectively; Two busbars are welded on the two ends of hollow copper tube abreast; The surrounding of the hollow copper tube of spiral surrounding becomes shell with poured with epoxy resin.This reactor volume is little, is suitable for IGCT power-phase module.But this reactor is deposited and is adopted epoxy resin as shell, and its corona-resistance property is not good, and between coil turn space more greatly, not antidetonation.
Publication number is that the patent application document of CN103474215A discloses a kind of novel water cooling reactor, disclosed in this reactor and CN101013623A patent document, reactor is similar to, its coil adopts hollow profiled aluminum pipe helical ring to be coiled into, it is characterized in that, the cross-over block being provided with isolation and supporting between the coil turn of annular, the coil of reactor additionally uses gold film half-stack package and haves mercy on.This reactor strengthens the stability between coil turn, makes reactor in vibration, avoid coil windings to produce position skew, also strengthens the insulating properties between coil turn simultaneously, avoid being short-circuited.
But the reactor of above-mentioned prior art is not all suitable for train current transformer, its reason is, the oscillation intensity in train operation is very large, longevity of service, and the shock resistance of its coil of reactor of prior art is not enough to the oscillation environment resisting long-time high strength; Moreover the reactor of the prior art the highest general class of insulation is F level, nargin is not enough, can show not Inverter fed motor, easily breakdown phenomenon in high voltage power transmission and transforming environment; 3rd, the reactor of prior art does not also possess lower temperature resistance, general poured with epoxy resin material temperature tolerance between-35 DEG C ~ 60 DEG C, if in extremely cold area, as northern China reaches the environment of-40 DEG C, then inequality of easily expanding with heat and contract with cold and ftractureing.
For the defect of above existing reactor, we devise the reactor described in the utility model, are particularly useful for crossing on the train in extremely cold area.

Further modified node method as the technical solution of the utility model:
Preferably, described corona-resistant insulation layer outwardly comprises 3 layers successively from nickel plating hollow copper tubing, i.e. polyimides fluorine 46 composite film layer of the polyimide film mica powder belt of half-stack package 2 times, half-stack package 2 times and half-stack package 1 alkali-free glass ribbon layer.Described polyimide film mica powder belt, polyimides fluorine 46 composite film layer and alkali-free glass ribbon layer are formed one corona-resistant insulation layer after stacked package again.Through repeated tests, above-mentioned 3 layers coated corona-resistant insulation layer have preferably effect.
Further, described coil is coiled into by the nickel plating hollow copper tubing after anti-corrosion treatment.
Further, described collets, upper clamping element, lower clamping element and screw rod are preferably made by low temperature material.The heat resistance of described low temperature material reaches less than-35 DEG C, guarantees that this reactor is applicable in the locomotive of pole low temperature ice box.
