IEC60884-1:2013中英文版对照-27 Creepage distances, clearances and distances through sealing compound 爬電距離、電氣間隙和透過密封膠的距離

27 Creepage distances, clearances and distances through sealing compound 爬電距離、電氣間隙和透過密封膠的距離

27.1 Creepage distances, clearances and distances through sealing compound shall be not less than the values shown in table 23. 
爬電距離、電氣間隙、和透過密封膠的距離應不小於表 23 所示的值。 
Compliance is checked by measurement. 
檢驗︰測量。 
For rewirable accessories, the measurements are made on the specimen fitted with conductors of the largest nominal cross-sectional area specified in table 3 and also without conductors. 
對於可拆線的插接裝置，要測量接上表 3 中規定最大截面積導線的試樣，還要測量不接導
線的試樣。 
The conductor shall be inserted into the terminal and connected in such a way that the core insulation touches the metal part of the clamping unit or, where the core insulation is prevented by construction from touching the metal part, the outside of the obstruction. 
將導線插入端子並連接使得導體絕緣觸及端子夾緊單元的金屬部件，或者如果導體絕緣的
架構尺寸阻礙與金屬部件接觸則觸及阻礙物的外緣。 
For non-rewirable accessories, the measurements are made on the specimen as delivered. 
對於不可拆線插接裝置，測量交貨狀態的試樣。 
Socket-outlets are checked when in engagement with a plug and also without a plug. 
插座要在插入插頭和不插插頭的兩種狀態下進行檢查。 
Distances through slots or openings in external parts of insulating material are measured using a metal foil in contact with the accessible surface other than the engagement face of plugs. The foil is pushed into corners and the like by means of the test probe 11 of IEC 61032, but is not pressed into openings. 
透過外部絕緣材料部件的槽或孔的距離，要對一種與可觸及表面（插頭的插合面除外）接觸的金屬箔進行測量，金屬箔要用 IEC 61032探棒 11的無節直線試驗指壓入凹角，但不壓入孔洞。 
For surface-type socket-outlets classified IP20 according to IEC 60529, the most unfavourable conduit or cable is introduced for a distance of 1 mm into the socket-outlet in accordance with 13.22. If the metal frame supporting the base of a flush-type socket-outlet is movable, this frame is placed in the most unfavourable position. 
對於根據 IEC 60529 的 IP20 明裝插座，要按 13.22 的規定將最不利的導管或導線插入插座內 1mm。如果支承暗裝插座的底座的金屬框架是可移動的話。則要將該框架放置在最不利位置。 
NOTE 1 The contribution to the creepage distance of any groove less than 1 mm wide is limited to its width. 
注 1︰寬度小於 1mm槽的爬電距離值，即為槽的寬度。 
NOTE 2 Any air-gap less than 1 mm wide is ignored in computing the total clearance. 
注 2︰計算總電氣間隙時，任何寬度不足 l mm的氣隙可忽略不計。 
NOTE 3 The surface on which the base of a socket-outlet for surface mounting is mounted includes any surface in contact with the base when the socket-outlet is installed. If the base is provided with a metal plate at the back, this plate is not regarded as the mounting surface. 
注 3︰明裝插座的基座的安裝表面包括安裝插座時與底座接觸的任何表面，如果底座的背面裝有金屬板，它不視作安裝表面。 
27.2 Insulating sealing compound shall not protrude above the edge of the cavity in which it is contained. 
絕緣密封膠不應凸出盛放該密封膠的腔穴的邊緣之外。 
27.3 Surface-type socket-outlets shall not have bare current-carrying strips at the back. 
明裝插座在背後不得有裸露的載流條。 
Compliance with the requirements of 27.2 and 27.3 is checked by inspection. 
27.2 條和 27.3 條的要求的檢驗︰觀察。
