Abstract
The utility model relates to a voltage regulating with load combination transformer, which comprises of a primary high-tension coil and a secondary low-tension coil that are winded on an iron core. The transformer is characterized in that a leading-in terminal of the primary high-tension coil utilizes an elbow cable connector assembly, a high-tension oil immersed four-position load switch S, a back up protection fuse FI and a plug-in fuse FII are in turn connected in series between primary high-tension coil leading-in terminals of A1, A2, B1, B2, C1, C2 and the primary high-tension coil; a voltage regulating switch with load and an automatic controller are connected on the primary high-tension coil. The utility model provides a voltage regulating with load combination transformer, which is capable of achieving full automatically voltage regulating, achieving three patterns operation of ring net, terminal, two-supply switch, and with two fuses protection, and with low loss and low nose.
Description
Affiliated technical field
The utility model relates to a kind of on-load voltage regulation combined transformer, belongs to the power transformer technical field.
Background technology
Present box type transformer has satisfied country and has required high pressure directly to enter the city in the city net is built, and gos deep into load center, the requirement of arterial street cableization.And not only economy but also convenient material benefit.But big of existing product is a non-excitation pressure adjustment, can not guarantee reliably that power supply quality and energy resource consumption are bigger.
Summary of the invention
The purpose of this utility model provides a kind of full-automatic on-load voltage regulation, can realize looped network, terminal, duplicate supply switch that three kinds of modes are moved, the on-load voltage regulation combined transformer of two fuse protected, low-loss, low noise.
The technical solution of the utility model is: a kind of on-load voltage regulation combined transformer, it is wound on the iron core by former limit high-tension coil and secondary low-voltage coil and constitutes.Former limit high-tension coil input terminal adopts the elbow cable-to-cable connector.Order is connected with high voltage oil immersion formula four position on-load switch S, backup protection fuse FI, plug-in fuse FII successively between former limit high-tension coil input terminal A1, A2, B1, B2, C1, C2 and former limit high-tension coil.On the high-tension coil of former limit, be connected with on-load voltage regulating switch and automatic controller.
The utility model is installed high voltage oil immersion formula four position on-load switch S in the high pressure end of incoming cables can realize that looped network, terminal, duplicate supply switch three kinds of modes and move.Being connected in series in the high pressure end of incoming cables, that this transformer has been had is two fuse protected for backup protection fuse FI and plug-in fuse FII.Automatically align by on-load voltage regulating switch under the automatic control of coil turn that pressure regulation makes former limit winding carrying out with on-load voltage regulating switch and automatic controller on the high-tension coil, make the output of secondary low pressure be in stable state at automatic controller.In a word, provide a kind of full-automatic on-load voltage regulation, can realize that looped network, terminal, duplicate supply switch that three kinds of modes are moved, a kind of on-load voltage regulation combined transformer of two fuse protected, low-loss, low noise.
