断路器的接线方式有板前、板后、插入式、抽屉式,用户如无特殊要求,均按板前供货,板前接线是常见的接线方式。 The connection modes of circuit breakers are front board, back board, insert board and drawer board. If users have no special requirements, they supply the circuit breakers according to the front board. Front board connection is a common connection mode. 1、板后接线方式:板后接线最大特点是可以在更换或维修断路器,不必重新接线,只须将前级电源断开。由于该结构特殊,产品出厂时已按设计要求配置了专用安装板和安装螺钉及接线螺钉,需要特别注意的是由于大容量断路器接触的可靠性将直接影响断路器的正常使用,因此安装时必须引起重视,严格按制造厂要求进行安装。 1. Post-board wiring mode: The most important feature of post-board wiring is that circuit breakers can be replaced or repaired without rewiring, and only the front power supply must be disconnected. Because of the special structure, the special installation board, installation screw and connection screw fuzhou.89ix.comhaikou.89ix.com shanghai.89ix.comtianjin.89ix.comchongqing.89ix.comxin.75ix.comhave been equipped in accordance with the design requirements when the product leaves the factory. It should be noted that the reliability of the contact of large capacity circuit breakers will directly affect the normal use of circuit breakers. Therefore, attention must be paid to the installation, and the installation must be carried out strictly according to the requirements of the manufacturer. 2、插入式接线:在成套装置的安装板上,先安装一个断路器的安装座,安装座上6个插头,断路器的连接板上有6个插座。安装座的面上有连接板或安装座后有螺栓,安装座预先接上电源线和负载线。使用时,将断路器直接插进安装座。如果断路器坏了,只要拔出坏的,换上一只好的即可。它的更换时间比板前,板后接线要短,且方便。由于插、拔需要一定的人力。因此中国的插入式产品,其壳架电流限制在最大为400A。从而节省了维修和更换时间。插入式断路器在安装时应检查断路器的插头是否压紧,并应将断路器安全紧固,以减少接触电阻,提高可靠性。 2. Plug-in wiring: On the installation board of the complete set of devices, first install a circuit breaker installation seat, six plugs on the installation seat, and six sockets on the connection board of the circuit breaker. There is a connecting plate on the surface of the mounting seat or a bolt behind the mounting seat, and the mounting seat is pre-connected with the power supply line and the load line. When in use, the circuit breaker is inserted directly into the mounting seat. If the circuit breaker is broken, just pull out the broken one and replace it with a good one. Its replacement time is shorter and more convenient than before and after the board. Because inserting and pulling need a certain amount of manpower. Therefore, for Chinese plug-in products, the shelf current is limited to a maximum of 400 A. Consequently, maintenance and replacement time are saved. Insert circuit breaker should check whether the plug of the circuit breaker is tightened, and should tighten the circuit breaker safely to reduce contact resistance and improve reliability. 3、抽屉式接线:断路器的进出抽屉是由摇杆顺时针或逆时针转动的,在主回路和二次回路中均采用了 3. Drawer wiring: The drawer of circuit breaker is rotated clockwise or counterclockwise by rocker, which is used in both main and secondary circuits. 插入式结构,省略了固定式所必须的隔离器,做到一机二用,提高了使用的经济性,同时给操作与维护带来了很大的方便,增加了安全性、可靠性。特别是抽屉座的主回路触刀座,可与NT型熔断路器触刀座通用。 The insertion structure omits the fixed isolator, achieves one machine for two purposes, improves the economy of use, brings great convenience to operation and maintenance, and increases safety and reliability. Especially the main circuit contactor base of drawer seat can be used with NT type fuse circuit breaker contactor base. |
