Background technology
Domestic large-scale power-supply device transformer outlet terminal all exists the bad problem of heat radiation in various degree, and method commonly used is that as schematically shown in Figure 1, but distinguished and admirable heat of cooling exchange efficiency is very undesirable with the axial flow blower cooling.
The secondary outlet terminal temperature height of 10000 kilovolt-amperes of rectifying and pressure-regulating transformers of mountain converting plant of rubber group is up to 55 degree, and traditional method is with axial flow blower 2 coolings, has used two axial flow blowers, to 1 cooling of six roots of sensation outlet terminal.
This apparatus features is:
1, the outlet terminal part of this device adopts two axial flow blower coolings, and the blower fan total capacity is 10 kilowatts, noise is very big, some are with corrosive gas also to be blown to simultaneously on the secondary terminal, and are very harmful to equipment, operator on duty's operate as normal around noise has directly influenced.;
2, this apparatus control portion is divided morely, contactor is arranged, air switch, intellective protector, load cable, signal lamp, distribution box, control circuit etc.;
3, converting plant direct current cabinet can empty silicon cell be non-cophase counter parallel connection, rectifying and pressure-regulating becomes the secondary outlet terminal and is 6, totally 12 brachium pontis owing to secondary outlet terminal heat, pass on the controllable silicon through brachium pontis at last, though controllable silicon has the water jacket cooling, but increased hot transmission again to silicon cell again from the terminal to the compensator, this device is main by the axial flow blower cooling, and seldom a part is air cooling, therefore motor tripping operation in a single day, secondary outlet terminal temperature is increased to 55 degree rapidly;
4, this device is in running, the six phase outlet terminal contacts area of finding it are little, cause the heating of compensation bus, seriously, particularly summer the ambient temperature height, it is more serious to generate heat, long-term operation can damage terminal and insulating case, influence exerting oneself of voltage regulating rectifier change, cause the contact-making surface oxidation, increase loss.The final voltage regulating rectifier transformer that damages; reduce its life-span; because the electrolysis process of chlor-alkali subsidiary factory is the core of whole chemical system; in case becoming meeting out of joint, voltage regulating rectifier causes whole chemical system paralysis; cause heavy losses to Chemical Manufacture, inflammable gas and the pernicious gas crisis person and device security that electrolysis simultaneously produces.
In present domestic device for high-power power electronic, also there is the water-cooled mode of application to lower the temperature to equipment, the secondary outlet terminal cooling how could give transformer with running water, this is the general technical issues that need to address of domestic each large and medium-sized enterprise.
Summary of the invention
The utility model utilizes distinguished and admirable heat abstractor effect bad for the terminal that solves existing volt-ampere voltage regulating rectifier transformer, the problem that noise is excessive, and a kind of water-cooling apparatus that is applied to voltage regulating rectifier transformer secondary outlet terminal is provided.
The utility model realized by following technical scheme, a kind of water-cooling apparatus that is applied to voltage regulating rectifier transformer secondary outlet terminal, and structure comprises and is installed in secondary outlet terminal both sides
The radiating tube of the structure of sinusoidal wave formula.Described radiating tube structure comprises between plurality of U-shaped copper pipe, the U-shaped copper pipe and being connected by aqueduct, and the valve at two ends and turnover pipe valve, and aqueduct connects into the U-shaped copper pipe a kind of structure of sinusoidal wave formula.
Described aqueduct is the PVC water pipe, and aqueduct is connected with the copper water nozzle with U type copper pipe joint, and U type copper pipe device is fixed on voltage regulating rectifier change secondary outlet terminal both sides by the CARBURIZING FURNACE FOR STAINLESS FASTENER nut and has constituted the complete water system cooling chain of a cover.
Its installation process that is used for the terminal cooling is: at first 12 cover U-shaped copper pipe cooling devices are separately fixed at the outlet terminal both sides, then on the U-shaped copper pipe water inlet copper mouth on the pvc water inlet pipe link terminal at one end, again the water outlet copper mouth of this side is connected with the PVC water pipe with the water inlet copper mouth of the U-shaped device of opposite side, be connected with cooling device on the adjacent terminal afterwards, order has connected six cooling devices on the terminal respectively like this.During this device work, cooling water flows to from the terminal of an end, advances 6 terminals and flows out from the faucet of the other end at last, enters next workshop and carries out 2 utilizations.
Also comprise the fixedly U-shaped copper coin of U-shaped copper pipe, and the CARBURIZING FURNACE FOR STAINLESS FASTENER nut.Its effect is welded on the copper soleplate for the U-shaped copper pipe is connect technology by brazing exactly, does not produce eddy current and does not generate heat with the CARBURIZING FURNACE FOR STAINLESS FASTENER nut is fixing.
This overlaps sine-shaped copper pipe cooling device and has set up the water route circulation of oneself separately, tap water pressure is 0.1 MPa, satisfied and cooled off the required water yield, the armrest movable valve is once adjusted to the right place on the flow of regulating water, and the running water after cooling is used flows to the reprocessing recycling.
Installation of the present utility model and using method and operation principle:
The U-shaped copper pipe is separately fixed at voltage regulating rectifier with CARBURIZING FURNACE FOR STAINLESS FASTENER becomes secondary outlet terminal both sides, connect with the PVC aqueduct between the U-shaped copper pipe, connect running water Inlet and outlet water pipe valve then.Because metallic copper has good heat transfer effect, the specific heat 0.39 * 10 of copper
3J/ (kg. ℃), it can fully absorb the heat of secondary outlet terminal, this device is exactly to utilize running water as heat-absorbing medium, remove to cool off voltage regulating rectifier and become the secondary outlet terminal, keep rectification to become the normal working temperature of secondary outlet terminal, water-cooled effective, the thermal transmission coefficient of water is 24 times of wind, and coefficient of heat transfer is 900 times of wind, and cooling evenly, noiseless, water was taken away the heat of terminal in the very first time through device, do not have scale problems, though summer the terminal temperature also 28 the degree below, original half fallen in temperature, and this kind scheme can be fit to solve the terminal heating problem of all 10,000 kilovolt-amperes of voltage regulating rectifier transformers.
The beneficial effects of the utility model: this device is efficient, environmental protection, noiseless, has simplified cooling process in the past, and control is convenient, and is simple to operate, avoided the outlet terminal heating problem, reduced the generation of electric accident, improved on-the-spot operating environment.Prolonged the useful life of transformer.Range of application: in the voltage regulating rectifier transformer that electrolysis process is used.
