The usage scope and technical features of tube-type tap-changer

    This is an new three- phase tube-type tap-changer,it is combined by the body of tap-changer and an operating turning framework, when the transformer is under non-energized state , we can turn over the tap position to change transformer ratio and stabilize output voltage,The single phase and “ 1+2” phase tube-type tap-changer are suitable for installation on vertical direction,but the three-phase tube-type product is suitable for vertical or horizontal installation .

    These series of products are specially designed for large or medium oil-immersed power transformer, full hermetically transformer or transformers for specially used , they are frequency normally on 50Hz or 60Hz, and suitable for flat type or bell-type oil tank , its Highest voltage for equipment is up to 252kV and below ,rated current up to 4000A and below. 

This product has many technical features and owned a certain of national patent right protection .

(1) Simple and lively appearance ,reliable structure equipped with solid construct pieces .

(2) Light moment , turn over tap position clearly . The product has technical design features as following : body pieces are restricted each other and functioned each other ,you can change the tap position freely and exactly ,compared with the same type of products , it has obvious superiority features.

(3) No conductors and switch cover being equipped on the outer body of product . This is a full hermetially outer insulation screen which can withstand high voltage impulse .so no puncture discharge will rise between the narrow gaps , even if the air gap of the tap-changer is very near the active body of the transformer.

(4) The inner structure of the tube- type tap-changer can be drawn out as a whole part , this helps to installation and maintenance.

WDG II 单相鼓形365bet足球
WDG II series de-energized drum-formed tap-changer

本开关由开关本体和操作机构组成,采用压缩弹簧、环形动触头,具有结构合理,操作简单,能自动定位,手感强,接触好等优点。适用于频率50Hz、60Hz,设备最高电压40.5kV、126kV、252 kV,额定电流200A~2500A的油浸式变压器,开关部份固定在器身或下部油箱箱沿.上,操作转动机构固定在箱盖上,在无励磁状态下分接调换。

This type of changer is comprised by tap-changer body and operating mechanism, Being adopted by crank principle ,compress spring and ring-type motive contact, They have the merits of reasonable in structure ,operating simply ,location automation,good in handing and contact reliable etc, It is suitable for oil-immersed transformer with frequency of 50 or 60Hz,highest voltage for equipment 40.5kV or 126kV and 252kV,rated current from 200 A to 2500A, The body of tap-changer is fixed on the tanking transformer or on the body of lower part of oil tank, The operating mechanism is located on the tank cover, they must be working under non-energized condition.

鼓形开关特点:

1、开关本体部分:
a、转动部位采用新结构,具有转动灵活,操作力矩小,使开关在干燥处理后(高温状态),也能正常操作;
b、增设了自动定位装置,动触头过“死点”后,能自动定位,消除了动触头偏位现象,具有操作手感强的特点;
C、增设了导向筒,使开关在二次装配时,操纵杆的插入准确,方便。
2、开关的操纵机构部分:
a、采用新的法兰压紧固定方式,机构的法兰可随开关本体档位角度任意转动,而不需调整档位指示角度;
b、只要把操纵杆按实际的长度进行有效的对接即可,使装配更为简化;
c、操作未到位时,手柄无法定位,使罩子无法戴.上,具有防止误操作功能。

New features of drum-formed tap-changer

1、The part of tap-changer body
a、The turning part of the tap-changer is made of new structure ,turning flexibly and small operating moment.It can work normally after the tap-changer is dried with high temperature.
b、The automatic orientation device is made in the switch,after the motive contact is passed through“ dead point', it can orientate by itself and eliminate the position excursion phenomena,This operation makes the tap-changer have strong handle feeling.
C、The direction guiding barrel is added in the switch,when the switch is assembled once again, the operating pole can be inset to the position exactly and conveniently.
2、The part of operating mechanism
a、The flange is fixed with new installation method, the flange on the operating mechanism can turn freely along with the turning angel of the tap-changer body. Adjustment the steps of tap-changer is not required.
b、Only connect rightly to the operating pole using its actual length, it makes assembly more easily.
C、When the tap-changer is turned to the end part of position, the handle pole can not be gone forward and the cover can' t be put on, this will prevent the tap-changer from any fault operation.
