Description
Technical field
The utility model relates to a kind of loaded capacity-regulated power transformer, belongs to power transformer technical field.
Technical background
In vast rural power distribution and the power utilization network such as downtown, industrial area, due to seasonal, timeliness is strong, the peak-valley difference of power load alters a great deal, common distribution transformer can not adjust capacity according to this Variation Features, causes the waste of a large amount of electric power resource, power supply reliability and of poor quality, for a change this situation, can select capacitance-adjustable transformer, but the loaded capacity-regulated switch of current loaded capacity-regulated transformer adopts cylindrical structure, vertical installation, major defect has following:
1, loaded capacity-regulated switch is placed in transformer body fuel tank, and when making Large Copacity, low voltage three-phase D.C. resistance is difficult to balance, makes fuel tank volume comparatively large simultaneously, too increases the consumption of transformer oil.
2, because loaded capacity-regulated switch and transformer body share a fuel tank, make transformer body, loaded capacity-regulated switch all needs to be fixed on top cover, need install, assembly difficulty is large simultaneously; Make transformer body safeguard, loaded capacity-regulated switch safeguard very difficult, during the urgent suspended core of transformer need loaded capacity-regulated switch is also hung out together simultaneously; Loaded capacity-regulated switch directly can not observe grease chamber's carbon deposit and aging conditions, tap contact and abrasion condition.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of novel structure, volume little, convenient for installation and maintenance, the loaded capacity-regulated transformer that power supply reliability is high.
The technical scheme realizing above-mentioned purpose is:
A kind of loaded capacity-regulated transformer, comprise transformer body fuel tank, loaded capacity-regulated switch, loaded capacity regulating voltage regulating switch tank, switch intelligent controller, bushing, low-tension bushing, transformer body, low-voltage current mutual inductor, pipe type oil-level gauge etc., it is characterized in that the horizontal layout of loaded capacity-regulated switch, independent loaded capacity-regulated switch tank is set; Preferably be arranged in transformer body low-pressure side; Loaded capacity-regulated switch tank is set up collection carbon groove, is preferably funnel type; Be provided with the insulating supporting dividing plate of binding post and switch static contact; Low-voltage current mutual inductor and the one-body molded cast of low-tension bushing, and low-tension bushing is arranged on transformer body top of oil-tank; On-line automatic oil-filtering apparatus set up by loaded capacity-regulated switch; Temperature sensor is set up, the temperature of Real-Time Monitoring coil, transformer oil, environment in transformer body fuel tank.
The beneficial effects of the utility model are as follows: more traditional loaded capacity-regulated transformer can simplify installation procedure; Reduce transformer main fuel tank overall dimension, general with non-regulated transformer fuel tank; The materials such as free carbon, metal particle and oxide thereof can be collected, improve loaded capacity-regulated switch reliability; Eliminate the insulating concrete cylinder of loaded capacity-regulated switch, open the fuel tank cap of loaded capacity-regulated switch, without the need to the contact getting final product maintenance switch of loosing core, transformer installation and maintenance and loaded capacity-regulated switch installation and maintenance can be carried out respectively, be independent of each other; Product with compact structure, volume reduces, more safe and reliable, installs, Operation and Maintenance is simple and convenient, decrease recessive defect.
