  一、电控柜内接线端子排的安装,应该合下列要求:

  The installation of terminal block in electric control cabinet shall meet the following requirements:

  (一)端子排无损坏,固定牢固,绝缘良好。

  The terminal block has no damage, is fixed firmly and has good insulation.

  (二)端子应有序号,端子排应便于更换且接线方便。

  The terminal shall have serial number, and the terminal block shall be easy to replace and connect.

  (三)回路电压超过400V都,端子板应有足够的绝缘并涂以红色标志。

  When the circuit voltage exceeds 400V, the terminal board shall be adequately insulated and painted with red mark.

  (四)强,弱电端子宜分开布置;应有明显标志并设空端子隔开或设加强绝缘的隔板。

  The strong and weak current terminals should be arranged separately; there should be obvious signs and the empty terminals should be separated or the partition board with strengthened insulation should be set.

  (五)正,负电源之间以及经常带电的正电源与合闸或跳闸回路之间,宜以一个空端子隔开。

  An empty terminal should be used to separate the positive and negative power sources as well as between the frequently charged positive power supply and the closing or tripping circuit.

  (六)电流回路应经过试验端子,其它需断开的回路宜经特殊端子或试验端子。试验端子应接触良好。

  The current circuit shall pass through the test terminal, and other circuits to be disconnected shall pass through the special terminal or test terminal. The test terminals should be in good contact.

  (七)潮湿环境宜采用防潮端子。

  Moisture proof terminals should be used in humid environment.

  (八)接线端子应与导线截面匹配,不应使用小端子配大截面导线。

  The connection terminal shall match the conductor cross section, and the small terminal shall not be used with the large cross-section conductor.

  (九)连接件均应采用铜质制品,绝缘件应采用自熄性阻燃材料。

  The connectors shall be made of copper products, and the insulating parts shall be made of self extinguishing flame retardant materials.

  (十)各电器,端子牌等应有尽标明编号,名称,用途及操作位置,其标明的字迹应清晰,工整,且不易脱色。

  The number, name, purpose and operation position of each electrical appliance and terminal plate shall be clearly marked, neat and not easy to be discolored.

  二、电控柜内电路接线配线,应该合下列要求:

  The circuit wiring in the electric control cabinet shall meet the following requirements:

  (一)按图施工,接线正确。

  The construction shall be carried out according to the drawing and the wiring shall be correct.

  (二)导线与电气元件间采用螺栓连接、插接、或压接线等到,均应牢固可靠。

  Bolt connection, plug connection, or crimping connection shall be adopted between the conductor and electrical components, which hall be firm and reliable.

  (三)电控柜内的导线不应有接头,导线芯线应无破损伤。

  There should be no joint for the conductor in the electric control cabinet, and the core wire of the conductor should be free from damage.

  用于连接门的电位器、控制台板等

  Potentiometer, console board, etc. for connecting doors

接线端子配线安装

  (四)电缆芯线和所配导线的端部均应标明其回路编号,编号应正确,字迹清晰且不易脱色。

  The end of the cable core and the conductor shall be marked with its loop number, which shall be correct, clear and not easy to decolorize.

  (五)配线应整齐、清晰、美观、导线绝缘应良好,无损伤。

  The wiring shall be neat, clear and beautiful, and the conductor insulation shall be good without damage.

  (六)每个接线端子的每侧接线宜为1根,得超过2根。对于插接式端子,不同截面的两根导线不得接在同一端子上;对于螺栓连接端子,当接两根导线时,中间应加平垫片。

  Each side of each terminal should be connected with 1 wire or more than 2 wires. For plug-in terminals, two conductors with different cross sections shall not be connected to the same terminal; for bolted terminals, when connecting two conductors, flat gasket shall be added in the middle.

  (七)电路接地应设专用螺栓。

  Special bolts shall be set for circuit grounding.

  (八)动力配线电路采用电压不低于500V的铜芯绝缘导线,在满足载流量和电压降及有足够机械强度的情况下,可采用不小于0。5m㎡截面的绝缘导线。

  The power distribution circuit adopts copper core insulated conductor with voltage not less than 500V. Under the condition of meeting the current carrying capacity, voltage drop and sufficient mechanical strength, the power distribution circuit can adopt no less than 0. Insulated conductor with a cross-section of 5mm2.
