摘要： A switch for use in transformer tap changing is modular in design, having standardized fixed contact units mounted in alignment on a base. Each contact unit has an electrical contact embedded in an insulating body, with a hollow bore formed through the insulating body and the embedded electrical contact. A cylindrical movable contactor having spaced contact bands is mounted on a shaft to be driven through the hollow bores of the fixed contact units between positions at which its contact bands engage the electrical contacts within adjacent fixed contact units. The electrical contacts of the fixed contact units are connected to different taps of the transformer to allow the transformer turns ratio to be adjusted by changing the position of the movable contactor. The drive shaft is connected by a mechanism to a handle mounted outside the tank of the transformer that can be operated to move the movable contact a selected distance to change the tap connections to the transformer.
摘要翻译：用于变压器抽头变换的开关是模块化的设计，具有在基座上对准安装的标准化固定接触单元。每个接触单元具有嵌入在绝缘体中的电触点，其中形成有穿过绝缘体和嵌入式电接触的中空孔。具有间隔开的接触带的圆柱形活动接触器安装在轴上，以通过固定接触单元的中空孔在其接触带接合相邻固定接触单元内的电触头的位置之间被驱动。固定接触单元的电触头连接到变压器的不同抽头，以通过改变活动接触器的位置来调整变压器匝数比。驱动轴通过机构连接到安装在变压器箱外部的手柄上，该手柄可以被操作以将可动触点移动到选定距离以改变到变压器的抽头连接。

摘要： A bus bar connector of fewer parts to be easily assembled where plural grooves are formed in the outer periphery of a guide plate so as to position and to prevent plural contact plates from inclining, and a supporting arm is provided at a part of the outer periphery of the guide plate whereby the shield is securely supported by fitting the supporting arm into an annular groove or an engaging hole formed in the inner wall of the shield. Also a half of the shield is integrally formed with the guide plate and coupled with the remaining half of the shield whereby the shield is fixedly supported as the guide plate is fixed to the conductive unit.
摘要翻译：一种用于容易组装的少量零件的母线连接器，其中在引导板的外周形成有多个槽以便定位和防止多个接触板倾斜，并且在外周的一部分设置有支撑臂，由此通过将支撑臂装配到形成在屏蔽件的内壁中的环形槽或接合孔中，屏蔽件被可靠地支撑。屏蔽体的一半也与引导板一体地形成并与屏蔽的其余一半结合，由此当导板固定到导电单元时，屏蔽件被固定地支撑。

摘要： A switching device having an open-ended hollow cylindrical housing with a number of slots in the sidewall. An insulative piston is slidably movable along the housing longitudinal axis and has a threaded central opening receiving a similarly threaded axle. A receptacle switch part fits onto a housing end and includes a central opening through which an unthreaded portion of the axle extends. Openings in the receptacle switch part each have a sleeve contact with outwardly extending tabs for electrical connection to cable wires, or the like. The piston has a plurality of pin contacts fixedly mounted thereto with portions extending from both sides of the piston for electrical connection to cable wires, for example, and which respectively align with a sleeve contact in the switch part. A further receptacle switch part is affixed to the housing other end. Rotative power drives the piston along the housing to effect connection between the contacts.

摘要： A plug-in type contact arrangement for high power electrical apparatus such as switch gear, wherein a fixed contact member carries a plurality of contact fingers having roller contacts mounted at one end thereof for reliably contacting a movable contact member when such movable contact member is forced into a contacting relationship with the fixed contact member and entering the cage-like receptacle formed by the circularly arranged contact fingers, and wherein the contact fingers are crimped at a predetermined point forming a first longitudinal portion and a second longitudinal portion arranged in different axial planes and connected by the crimping region, thereby transforming the contact pressure formed between the movable contact member and the roller contacts into a torsional load exerted on the contact fingers.
