【正文】 a thermal element. 熱脫扣保護 器 ：由 流過熱元件的 電流產(chǎn)生的熱量使電路斷開 。 SUPPLEMENTARY PROTECTOR － A manually resettable device designed to open the circuit automatically on a predetermined value of time versus current or voltage within an appliance or other electrical equipment. It may also be provided with manual means for opening or closing the circuit. 輔助保護 器 ： 用在 電器或其他電力設(shè)施 中，當電流或電壓 設(shè)施 ,在電流或電壓達到設(shè)定值時 間 斷開電路 ，并 手 動復(fù)位 的 裝置。 SHUNT TRIP PROTECTOR － A protector with a trip mechanism energized by a separate source of voltage or current that may be derived from the main contact circuit or from an independent source. The trip mechanism may be either of the overcurrent type or the voltage actuated type. 分勵脫扣保護 器 ： 由另一 電流或電壓 觸動從而 脫扣的保護器，該電流或電壓 可以來自主接觸電路或獨立來源。 OVERCURRENTTRIP PROTECTOR － A thermal or magic trip protector intended to trip the contact circuit when the current through the thermal element or trip coil, which is in series with contact circuit, exceeds a predetermined value. 過 電流 脫扣保護 器 ： 與主回路串連、當通過 熱元件或脫扣線圈的電 流超出 預(yù)期值時 脫扣的熱脫扣 或 磁脫扣保護器。 Automatic reset devices designed to open the circuit automatically on a predetermined value of time versus current or voltage within an appliance or other electrical equipment are covered by the Standard for SolidState Controls for Appliances,UL244A. 用于 電器或其他 電力設(shè)施 ，能根據(jù)電壓值在預(yù)定的時間自動斷開的自動復(fù)位裝置，使用 UL244A 2 Glossary 術(shù)語表 AUXILIARY SWITCH － A switch that is mechanically operated by the main contact switching mechanism. 輔助開關(guān)－由主觸頭開閉機械操作的開關(guān) FIELD WIRING TERMINALS － Any terminal to which a supply or other wire can be connected by an installer in the field, unless the wire is provided as part of the appliance or other electrical equipment and a pressure terminal connector, soldering lug, soldered loop, crimped eyelet, or other means for making the connection is factoryassembled to the wire. 現(xiàn)場接線：安裝者在現(xiàn)場連接的端子，除非接線為儀器或其它電氣設(shè)備的一部分，壓線接線器、焊接片、焊接環(huán)、起皺彎曲孔，或者其它方式來進行的工廠組裝接線。 This standard also covers accessory devices that may be installed in or on the protector to perform a secondary function. Examples of accessories are alarm and auxiliary switches. 本標準 也 涵蓋安裝在保護器內(nèi)外，實現(xiàn)附屬功能的附件裝置，如警報和輔助開關(guān)。 The acceptability of a protector in any particular application depends upon its ability to be used continuously under the conditions that prevail in actual service. Accordingly, for a particular application a protector may be affected by the requirements for the equipment it is used in, and it may be necessary to additionally evaluate features or performance characteristics that are not specified in this standard. 任意特定應(yīng)用下的保護器 的 可接受性取決于其 實際 使用狀況下持續(xù)工作 的能力 。Supplementary Protectors for Use in Electrical Equipment 設(shè)備用輔助電路保護器 CONTENTS 目錄 INTRODUCTION 導(dǎo)言 1 Scope 應(yīng)用范圍 .................................................. 5 2 Glossary 術(shù)語 ................................................... 5 3 Components .部件 ................................................ 5 4 Units of Measurement 度量單位 ................................... 6 5 References . 參考 ............................................... 6 CONSTRUCTION 結(jié)構(gòu) 6 General 總則 .................................................... 8 7 Corrosion Protection 防腐蝕 ..................................... 8 8 Insulating Materials 絕緣材料 ................................... 9 9 CurrentCarrying Parts 載流部件 ................................. 10 10 Wiring Terminals 接線端子 ...................................... 11 11 Pressure Wire Connectors壓線接線 ............................... 11 12 Wiring Leads 引線 .............................................. 11 13 WireBinding Screw Terminals 螺釘式接線端子 .................... 12 14 Mounting 安裝 .................................................. 12 15 Operating Mechanism 操作機構(gòu) ................................... 12 16 Spacings 間隙 .................................................. 13 17 Clearance and Creepage Distances 電氣間隙和爬電距離 ............ 14 PERFORMANCE 性能 18 General 總則 ................................................... 16 OVERCURRENT PROTECTORS 過電流保護器 19 Calibration 校準 ............................................... 18 20 Temperature 溫升 .............................................. 18B 21 Overload Test 過載 ..............................................21 22 Endurance 壽命 ................................................. 26 23 Dielectric VoltageWithstand 介電 .............................. 27 23A Dielectric Strength and VoltageWithstand Tests 介電強度和耐壓試驗 .............................................27 Dielectric strength test 介電強度 ........................... 27 Voltagewithstand test 耐壓 ..................................27 Details 細則 ................................................ 28 24 Recalibration 再校準 ........................................... 28 25 Short Circuit 短路 ..............................................28 OTHER PROTECTORS 其它保護器 26 Auxiliary Switches 輔助開關(guān) .................................... 34 General 總則 ................................................. 34 Temperature 溫升 ............................................. 34 Overload 過載 ................................................ 34 Endurance 壽命 ............................................... 36 Dielectric voltagewithstand 介電 ............................ 37 27 OvervoltageTrip Appliance Protectors 過電壓保護器 ............. 37 General 總則 ................................................. 37 Temperature 溫升 ............................................. 37 Overvoltage 過電壓 ........................................... 37 Operation 操作 ............................................... 37 Overload 過載 ................................................ 37 Endurance 壽命 ............................................... 37 Dielectric voltagewithstand 耐壓 ............................ 38 28 UndervoltageTrip Protectors 欠電壓
