A kind of ZPS types phase-shifting rectifier transformer

Technical field

It the utility model is related to transformer technology field, more particularly to a kind of ZPS types phase-shifting rectifier transformer.

Background technology

Phase-shifting rectifier transformer is one kind of rectifier transformer, is both a kind of important factories and miness electrical equipment, also can conduct Measuring room and the precision instrument in laboratory.

Rectifier transformer is the power transformer of rectifying installation.The characteristics of rectifying installation is original side's input AC, and pair side By exporting direct current after rectifier element.Unsteady flow is rectification, the general name of three kinds of working methods of adverse current and frequency conversion, and rectification is wherein to apply It is widest a kind of.Transformer as fairing power supply is referred to as rectifier transformer.Industrial rectification DC power supply is big Part be all as AC network as obtained from rectifier transformer and rectifying installation.

Oil-filled transformer low pressure winding is in addition to low capacity uses copper conductor, typically all using copper foil around the drum type brake taken out Structure；High pressure winding uses multi-layer cylindrical structure, is allowed to the ampere-turn distribution equilibrium of winding, and leakage field is small, high mechanical strength, resists short Road ability is strong.Unshakable in one's determination and winding each employs the fastening part such as security measure, device height, low-voltage lead all band self-locking anti-loosing spiral shells Mother, employ and do not hang core structure, the top shake of transport can be born.Because corrugated plate instead of oil conservater, make transformer oil and the external world Isolation, thus effectively prevent oxygen, moisture entrance and cause the decline of insulating properties.According to above performance, ensure Oil-filled transformer need not change oil in normal operation, greatly reduce the maintenance cost of transformer, while extend change The service life of depressor.

At slack seasons, load electricity consumption is mainly electric consumption on lighting to the distribution transformer run at present, and power load is smaller, Main running status was accounted in 1 year；When returning to one's native place in busy farming season or the Spring Festival, transformer load can be significantly increased, even up to 1.5 times And above overload, easily there is situations such as transformer overload scaling loss, low voltage.Power network electricity consumption imbalance can have a strong impact on The load operation conditions of distribution transformer, when distribution transformer is chronically at light running, even overloaded in high capacity in short term During operation, grid power equipment is easily caused to damage or burn, with the development of country, power load sharply increases, particularly In the peak of power consumption period, often there is running overload in transformer, not only shortens the service life of transformer, more has and burns change Depressor causes bigger disaster hidden-trouble.If use Large Copacity transformation merely in order to meet short time running overload needs Device, disposable input cost is high, and operating cost is high, uneconomical, therefore it is required that distribution transformer has stronger overload capacity.

Such as Application No.：201520874064.4 Chinese patent disclose a kind of oil immersed type high overload distribution transformer Device, it includes casing, case lid and the winding being encapsulated in the casing, coolant, the winding is filled with the casing It is immersed in the coolant, it is characterised in that：The winding include radially being sleeved on successively low-voltage coil in iron core column and High-tension coil, pad is provided with and is dielectrically separated from cloth between the winding layer in the low-voltage coil per radially adjoining, in the high-tension coil Pad is dielectrically separated from paper between winding layer per radially adjoining, form the low-voltage coil and high-tension coil it is some around If radially uniform distribution is lined with dried layer insulating point gummed paper in layer, also fixation being lined between low-voltage coil and high-tension coil One layer of insulating point gummed paper, it is equally distributed on the insulating point gummed paper to be fixedly installed some insulation parallel with the iron core column Stay, the length of the insulating stay is not shorter than the width of the high-tension coil and low-voltage coil in the axial direction, described in every piece Surrounded out between every adjacent two insulating stays on insulating point gummed paper one axially through oil duct；Oil immersion disclosed in this application Formula high overload distribution transformer by select resistant to elevated temperatures insulating materials and high-flash transformer Cooling liquid, improve related elements and The heat resistance of insulating element, strengthen the resistant to elevated temperatures ability of transformer, reach and improve distribution transformer overload capacity, ensure base On the premise of this electricity capacity, both ensure the demand of the long-term electricity consumption of Smaller load, and take into account the demand of the short-term electricity consumption of overload again.
