Abstract
A three-phase oil immersion type non-excitation voltage regulation distribution transformer structurally comprises an oil tank, a high voltage porcelain bottle, a low voltage porcelain bottle, a non-excitation voltage regulation switch, a tank cover, a tank edge, a corrugated sheet, an oil discharging valve, a tank bottom, a tank bottom channel steel, an iron core, a clamping piece and a coil. The transformer can automatically convert voltage and can adjust high voltage to voltage grade utilized by residents. A non-excitation tap switch can adjust the voltage grade in absence of the excitation, and therefore stable voltage can be used by the residents.
Description
Technical field
The utility model belongs to field of electrical equipment.
Background technology
Transformer is the static electrical equipment that the AC energy of a certain voltage, electric current, the number of phases is transformed into the AC energy of another kind of voltage, electric current, the number of phases.
Nearly all be to use transformer at present in electric power, telecommunications, automation control system, along with the electrified development of industrial and mining enterprises, various industrial production mechanical electric equipment also often need to use transformer, according to different places, different environments for use, the transformer of various difference in functionalitys arises at the historic moment.
The primary structure of transformer is iron core and winding.How increasing new element in transformer, make it to have under no excitation condition, by changing the transformer high-voltage coil coil turn to reach the function of adjusting low voltage voltage, is characteristics of the present utility model.
Summary of the invention
The purpose of this utility model is to provide a kind of under no excitation condition according to actual needs, by changing the transformer primary winding number of turn reaching the function of adjusting secondary voltage, thus the transformer of stable electric energy transmitting.
The technical scheme that this product adopted is: through high-tension coil, be converted to magnetic energy by alternating current by the cable transmission high-tension electricity, magnetic energy is again by unshakable in one's determination, senses low-voltage coil and is converted to electric energy and exports from low-pressure side.
The structure of this product comprises: at the bottom of fuel tank, high-tension porcelain insulator, low pressure porcelain vase, non-excitation pressure adjustment switch, case lid, case edge, corrugated plate, oil discharging valve, the case, case kerve steel, iron core, folder, coil.
High-tension porcelain insulator (2) and low pressure porcelain vase (3) are by being bolted on the case lid (5), the lead-in wire that has conducting rod to be connected to coil (14) in the middle of the porcelain vase is lifted one's head, case is welded on the fuel tank (1) along (6), case along last perforate again with case lid (5) on several screws of hole, screw rod joins, thereby fuel tank (1) has been sealed, 4 sides of fuel tank difference weld side is to corrugated plate (7) and forward corrugated plate (8), the fuel tank bottom welds together with (10) at the bottom of the case, following welding case kerve steel (11) at the bottom of the case, oil discharging valve (9) is equipped with near the place at the bottom of the case in the bottom of fuel tank, fuel tank internal is made of device body and transformer oil, in the device body by unshakable in one's determination (12) as support, place coil (14) in the iron core, coil lead links to each other with off circuit tap changer (4), off circuit tap changer is installed in the middle part perforate of case lid (5), and upper and lower sides unshakable in one's determination passes through bolt by folder (13).
The beneficial effects of the utility model are: but the transformer automatically converting voltage, can be the electric pressure of high voltage adjusting to residential electricity consumption.Off circuit tap changer can be under the condition of no excitation the regulation voltage gear, thereby allow the resident use stable voltage.
