Taiwan Hui Electric Switch Factory sell writing | JCZ5-400/12KV | Vacuum Contactor | AC Contactor | Work 0577-62906996 18066307033 one, working conditions a height of not more than 2000 meters above sea level. 2 Ambient air temperature: -25 ~ +40 ℃. 3 air relative humidity: ambient air temperature of +25 ℃ less than 50%, at lower temperatures can have a higher relative humidity. Wet month average temperature of the is +25 ℃ O'clock, the monthly mean big relative humidity of was 90%. Four mounting surface and the vertical gradient does not exceed 15 °. Installation category is usually the type Ⅲ. 5 Environmental pollution degree 3. 6 vibration not more than 30 m / s field. Second, the main technical parameters control voltage: AC220V AC380V Rated current: 160A | 250A | 400A | 630A Rated voltage: 1140V | 6KV | 7.2KV | 10KV | 12KV poles: 3 poles | 4 pole | 5-pole three, structure and working principle contacts from the vacuum switch tube, insulated frame, boom, magnetic cage, electromagnetic operating mechanism and fairing components. Electromagnetic operating mechanism made of the core, the coil, the magnetic pole plate, the armature plate, shaft, arm and other components. Static conductive plate vacuum switch tube by screws fixed to the insulating frame, insulation around the frame and the support plate and support bracket with screws magnetic coupling. When the the coil is energized after the armature suck and shut, driven boom and movable lead rod, etc., so that the vacuum switch tube moving contact movement, associated with static contact contact, so contact device is in the closed state. When the coil power, under the action of the reaction force spring armature plate release, static and dynamic contact separation to make contacts in the switching status. Electromagnetic operating mechanism made of the core, the coil, the magnetic pole plate, the armature plate, shaft, arm and other components. Auxiliary contacts at one end of the armature plate, driven by the armature moves up and down movement of auxiliary contacts. Fourth, installation, adjustment and replacement of days off tube 1. ⑴ installation should be checked before installing the mounting surface, the mounting surface is not flat gaskets adjusted. ⑵ with screw and lock washer will contactor mounting plate. ⑶ connect the main circuit inlet and outlet, the AC power cord is connected to the control terminals and connect the ground wire. 2. Adjust When the contact parameters do not meet the requirements or needs replacing vacuum switch tube be adjusted as follows: ⑴ spherical joints loosen the lock nut. ⑵ rotating spherical surface Couplings Flange, causes the contacts to has just disconnect the (with a multimeter low-resistivity stalls measured) and repeatedly adjusted so that the three consistent. ⑶ clockwise spherical joints to the flange, so that open distance up to standard requirements. ⑷ Tighten flange nut moving. Since the structure size guarantees overtravel no longer adjusted. ⒊ replace the vacuum switch tube when the vacuum drop or other reasons, the need to replace damaged vacuum switch. ⑴ When the static and dynamic contact separated from state under the, with the 2500V megger measured static and dynamic contact of the interlayer insulating resistance is less than 60 megohms should be replaced with vacuum switch tube. ⑵ Loosen the main circuit cable screw connection and soft, soft disengaged join line. ⑶ Unscrew static conductive plate insulated box screws. ⑷ to move the pin end of the compression spring contacts turn 90 degrees. ⑸ Remove the vacuum switch tube assembly. ⑹ Removing the spherical surface fitting assembly, Remove switch tube. ⑺ will be for the vacuum switch tube attached to the above in reverse order on the contactor. Tighten locknut, be careful not to twist the bellows in the state. After replacing the switch to re-adjust the open distance. -------- The following are CKJ series vacuum contactors Model CKJ5-63 AC vacuum contactor CKJ5-80 AC vacuum contactor CKJ5-125 AC vacuum contactor CKJ5-160 AC vacuum contactor CKJ5-250 AC vacuum contact device CKJ5-400 AC vacuum contact device CKJ5-630 AC vacuum contact device CKJ5-800 AC vacuum contact device CKJ5-1000 AC vacuum contact device CKJ5-1250 AC vacuum contact device CKJ3-800 AC vacuum contact device CKJ3-1000 AC vacuum contactor device CKJ3-1250 AC vacuum contact device CKJ3-1600 AC vacuum contact device CKG3-160 AC vacuum contact device CKG3-400 AC vacuum contact device CKG3-250 AC vacuum contact device CKJ5-1600 AC vacuum contact device JCZ7-160 AC vacuum contact device JCZ7-250 AC vacuum contact device JCZ7-400 AC vacuum contact device JCZ7-630 AC vacuum contact device CKG4-160 AC vacuum contact device CKG4-250 AC vacuum contact device CKG4-400 AC vacuum contact device CKG4-630 AC vacuum contact device EVS -160 AC vacuum contactor EVS-250 AC vacuum contactor EVS-400 AC vacuum contactor EVS-630 AC vacuum contactor JCZ5-160 AC vacuum contactor JCZ5-250 AC vacuum contactor JCZ5-400 AC vacuum contactor JCZ5- 630 AC vacuum contact device CKJ5-63 AC vacuum contact device CKJ5-80 AC vacuum contact device CKJ5-125 AC vacuum contact device CKJ5-160 AC vacuum contact device CKJ5-250 AC vacuum contact device CKJ5-400 AC vacuum contact device CKJ5-630 AC vacuum contactor CKJ5-800 AC vacuum contactor CKJ5-1000 AC vacuum contactor CKJ5-1250 AC vacuum contactor CKJ3-800 AC vacuum contactor CKJ3-1000 AC vacuum contactor CKJ3-1250 AC vacuum contactor CKJ3-1600 AC Vacuum Contactor CKG3-160 AC vacuum contactor CKG3-400 AC vacuum contactor CKG3-250 AC vacuum contactor JCZ7-160 AC vacuum contactor JCZ7-250 AC vacuum contactor JCZ7-400 AC vacuum contactor JCZ7-630 AC vacuum contact device CKG4-160 AC vacuum contact device CKG4-250 AC vacuum contact device CKG4-400 AC vacuum contact device CKG4-630 AC vacuum contact device EVS-160 AC vacuum contact device EVS-250 AC vacuum contact device EVS-400 AC vacuum contactor device EVS-630 AC vacuum contactor JCZ5-160 AC vacuum contactor JCZ5-250 AC vacuum contactor JCZ5-400 AC vacuum contactor JCZ5-400 AC vacuum contactor vacuum contactor manufacturers, vacuum contactors prices, vacuum contactors Model , the vacuum contact device parameters I have company Province, three sales indicators: Anhui Province,: Anqing City,; Bengbu City; Bozhou City,; Chaohu City; Chizhou city; Chuzhou City; Fuyang City; Hefei City; declared the city; Huaibei City; Huainan City; Huangshan City; Lu'an City; Ma'anshan City; Suzhou City; Tongling City; Wuhu City; Gansu Province: Silver City; Dingxi City; Gannan Tibetan Autonomous Prefecture; Jiayuguan City; Jinchang City; Jiuquan City; Lanzhou City; Linxia Hui Autonomous Prefecture; Longnan City; Pingliang City; Qingyang City; Tianshui City; Wuwei City; Zhangye City;, Guangdong Province,: Dongguan, City,; Foshan City,; Guangzhou City,; Jiangmen City; Meizhou City,; Qingyuan City; Shenzhen City; Zhaoqing City; Guangxi: Chongzuo City; Fangchenggang City; Hezhou; Laibin; Liuzhou; Nanning City; Qinzhou City; Wuzhou City; Yulin City; Guizhou Province: Anshun City; Bijie area; Guiyang; Liupanshui City;; Tongren Prefecture; Zunyi City; Hebei: Baoding ; Cangzhou City; Chengde City; Handan City; Hengshui City; Langfang City,; Qinhuangdao City,; Shijiazhuang City; Tangshan City; Xingtai City; Zhangjiakou City;, Henan Province,: Anyang City; Hebi City,; Jiaozuo City; Kaifeng City; Luoyang City; Luohe City,; Nanyang City; Pingdingshan City; Puyang City; Sanmenxia City; Shangqiu City; Xinxiang City; Xinyang City; Xuchang City; Zhengzhou City,; Zhoukou City; Zhumadian City; Heilongjiang Province,: Daqing City; Harbin City; Hegang City; Heihe City ; Jixi City; Jiamusi City; Ezhou; Mudanjiang City; Qitaihe City; Qiqihar City; Shuangyashan City Suihua City; Yichun City; Jilin: White City; Hakusan City; Changchun City; Jilin; Liaoyuan City; Siping City ; Songyuan City; Tonghua City; Yanbian; JiuTaiShi; Jiangsu Province: Changzhou; Huai'an City; Nantong City; Suzhou City; Suqian City; Wuxi; Xuzhou City; Yangzhou City; Zhenjiang City; Shandong Province: Binzhou; Texas City; Dongying City; Heze City; Jinan City; Jining City; Laiwu City; Liaocheng; Linyi City; Qingdao City; Rizhao City; Tai'an City; Weihai City; Weifang City; Yantai City; Zaozhuang City; Zibo City, Shanxi Province: Changzhi City,; Datong City; Jincheng City; Jinzhong City; Linfen City; Luliang City; Shuozhou City; Taiyuan City; Xinzhou City; Yangquan City,; Yuncheng City Shaanxi Province: Ankang City,; Baoji City,; Hanzhong City,; Shangluo City; Tongchuan City ; Weinan City; Xi'an City; Xianyang City; Yan'an City; Yulin City
