Description

電気回路の接続および切断は、電気回路そのものと同じくらい古く、回路に接続された電気機器への電力を、「オン」の状態と「オフ」の状態との間で切替える方法としてよく用いられている。回路の接続および切断のために一般的に用いられる装置の一例は、接触器である。接触器は、１つ以上の装置または電源に電気的に接続される。接触器は、装置へ入力される、または装置から出力される電力を制御するために、回路を中断または完成できるように構成されている。従来型の接触器のひとつが、気密封止接触器である。 Connecting and disconnecting electrical circuits is as old as the electrical circuit itself and is often used as a method of switching power to electrical equipment connected to the circuit between an "on" state and an "off" state. there is One example of a device commonly used to connect and disconnect circuits is a contactor. A contactor is electrically connected to one or more devices or power sources. The contactor is configured to interrupt or complete a circuit to control power input to or output from the device. One conventional type of contactor is a hermetically sealed contactor.

本体１０２は、接触器装置１００の種々の内部部品を収容する本体１０２の内部空間が気密封止されるように構成され得る。この気密封止された構成は、電気的負性ガスの使用と併用すると、隣接する導電性要素間の電気アークの軽減または防止を促進することができ、いくつかの実施形態では、空間的に離間する接触子間の電気的分離を促進する。いくつかの実施形態では、本体１０２は真空状態であり得る。本体１０２は、電気機器を気密封止するあらゆる周知の方法を使って気密封止することができる。気密封止機器の例には、米国特許第７，３２１，２８１号、７，９４４，３３３号、８，４４６，２４０号、９，０１３，２５４号に記載のものを含み、これらの特許は全て本願の譲受人であるギガヴァックインコーポレーテッドに譲渡されたものであり、これらの特許の全内容は参照により本願に援用される。 Body 102 may be configured such that the interior space of body 102 that houses the various internal components of contactor device 100 is hermetically sealed . This hermetically sealed configuration, in conjunction with the use of an electrically negative gas, can help reduce or prevent electrical arcing between adjacent electrically conductive elements, and in some embodiments is spatially Promotes electrical isolation between spaced apart contacts. In some embodiments, body 102 may be under vacuum. The body 102 can be hermetically sealed using any known method of hermetically sealing electrical equipment. Examples of hermetically sealed devices include those described in U.S. Pat. All are assigned to Gigavac, Inc., the assignee of this application, and the entire contents of these patents are incorporated herein by reference.
