液压配件与维修

产品描述

交流接触器广泛用作电力的开断和控制电路。 交流接触器利用主接点来开闭电路，用辅助接点来执行控制指令。 主接点一般只有常开接点，而辅助接点常有两对具有常开和常闭功能的接点，小型的接触器也经常作为中间继电器配合主电路使用。 从而起到远程控制或弱电控制强电的功能. 交流接触器的接点，由银钨合金制成，具有良好的导电性和耐高温烧蚀性。  交流接触器又分永磁式交流接触器和电磁式交流接触器. 交流接触器的动作动力来源于交流电磁铁，电磁铁由两个“山”字形的幼硅钢片叠成，其中一个固定，在上面套上线圈，工作电压有多种供选择。为了使磁力稳定，铁芯的吸合面，加上短路环。交流接触器在失电后，依靠弹簧复位。 另一半是活动铁芯，构造和固定铁芯一样，用以带动主接点和辅助接点的开短。

AC contactors are widely used in power interruption and control circuits. The communication contactor uses the main contact to open and close the circuit, and uses auxiliary contacts to execute control instructions. The main contact usually only has a normally open contact, while the auxiliary contact often has two pairs of contacts with normally open and normally closed functions. Small contactors are also often used as intermediate relays in conjunction with the main circuit. Thus achieving the function of remote control or weak current control of strong current The contacts of the communication contactor are made of silver tungsten alloy, which has good conductivity and high temperature erosion resistance. AC contactors are divided into permanent magnet AC contactors and electromagnetic AC contactors The action power of the AC contactor comes from the AC electromagnet, which is composed of two "mountain" shaped young silicon steel sheets stacked together, one of which is fixed and a coil is placed on top. There are multiple working voltages to choose from. In order to stabilize the magnetic force, a short-circuit ring is added to the suction surface of the iron core. After losing power, the AC contactor relies on a spring to reset. The other half is a movable iron core, constructed similarly to a fixed iron core, used to drive the opening and closing of the main and auxiliary contacts.
