为什么会这样呢?其实就是接线不正确的原因,这种错误往往出现在三相四线配电系统当中。下面咱们就讲一下漏电保护器在三相四线系统中的接线方法和注意事项。三相四线即地线、零线合一。出现上述所说的跳闸情况时,往往是将设备电缆中的四根线直接接到漏电保护器下火。漏电保护器而电缆的另一端,设备操作箱内的地线接到了操作箱金属外壳接地端子上。而且操作箱内有220V的用电设备,比如接触器、指示灯、照明灯。这些220V用电设备的零线与接地端子相通。

Computer shielded cable; Purpose: high voltage insulation with small interface constant. Use to ground, and the screen, the total screen (or three quad twisted, group screening, group screen a total screen), such as structure form, with a small dielectric loss, the transmission ability is strong, resistant performance is good wait for a characteristic, can reliable transmission weak analog or digital, can be widely used in electricity, metallurgy, petroleum, chemical, textile sites detection and control of the door or by computer automation instrumentation, and general industrial computer. Relevant technical indicators: reference BS5308 IEC189 and British second, product code 1 and code the DJ - (series code) electronic computer shielded cable Y - (insulation code) high-pressure polyethylene F - (insulation code) fluoroplastic V - (sheath code) polyvinyl chloride (R - said many strands of soft wire core P - (block code) copper mesh shielding P1 tin plated copper mesh shielding P2 copper tape screened P3 aluminum-plastic composite membrane shielding for example 1:3, product specifications order 7 (14) to 1.0 was computer shielded cable can be represented as: (1) total shielding DJYVP7 * 2 * 1.0mm2 (2) partial shielding multiple strands of soft line DJYPVR7 * 2 * 1.0mm2 (3) total shielding type DJYPVP7 * 2 * 1.0mm2 Type (1) packet shielding DJYPV3 x 3 x 0.75 was (group 2) screen a total screen DJYPVP3 x 3 x 0.75 was three, model name and use range model name using range DJYVPDJYPVDJYPVP total shielding polyvinyl chloride polyethylene insulating sheath computer cable shielding polyvinyl chloride polyethylene insulation group sheathed electronic computer cable shielding total shielding polyvinyl chloride polyethylene insulation group sheathed electronic computer cable 1, fixed for laying indoors, in cable trench or pipe 2, cable long-term working temperature: - 20 ℃ + 65 ℃, the cable laying temperature is lower than 0 ℃, the bending radius should not less than 10 times of cable diameter DJYVPR DJYPVR DJYPVRP total shielding polyvinyl chloride polyethylene insulating sheath computer with a soft cable shielding polyvinyl chloride polyethylene insulation group sheathed computer with a soft cable shielding total shielding polyvinyl chloride polyethylene insulation group with a soft cable sheath computers shows that: (1) flame retardant cable (oxygen index greater than 30) need to add code "out" in front of the model. For example, zr-djypv zr-djypvp et al. (2) armored (steel belt armored) cables need to add code "22" in the lower right corner of the model, such as: DJYPV22 djypvpppvp22, etc. The cable is mainly used for ac or dc 300V or below and can work normally when 500V or below.
