E3S-GS3E4 / / Bao Tong Electric Co., Ltd. is located in the "China Electric Capital" -,, Yueqing City,, Zhejiang Province,, Liushi Town,. Founded in 2012, the company specializes in producing agent sales famous industrial electrical brands: ABB, Siemens, Schneider, Shanghai People's Republic of Korea LS, Omron, Changshu switch, Shihlin mechanical and electrical. The main products are: contactors, miniature circuit breakers, relays, sensors, photoelectric switches, transformers, inverter, soft start, complete product specifications, price, After several years of hard work, the production adds advanced equipment and technical staff, has accumulated a certain amount of capital and production terminal design and manufacturing experience. The low-voltage contactors mainly by the electromagnetic system, contact system, arc system and other parts. ① electromagnetic system: electromagnetic system includes a solenoid coil and the core, is an important part of the low voltage contactor, and rely on it to drive the contacts closed and disconnected. (2) Contact System: Contact the operative part of the low-voltage contactors, including the main contacts and auxiliary contacts. The role of the main contacts is making and breaking the main circuit to control a larger current, auxiliary contacts in the control loop, in order to meet the requirements of the various control mode. ③ interrupter system: arc extinguishing means used to ensure that the contacts when the circuit is disconnected, reliably extinguish the arc generated, to reduce the damage of the arc contacts. To quickly extinguish the arc when disconnected, usually low-voltage contactors with interrupter device, generally use the the half sealed longitudinal seam clay interrupter cover, and equipped with a magnetic arc blow circuit. ④ Other parts: insulating shell, spring, short-circuit ring, transmission mechanism. Low-voltage series LC1-D series AC low voltage contactor works: When the low-voltage contactor solenoid is not energized, the spring reaction force and the armature weight of the main contacts remain off position. When the solenoid is turned on by the control circuit to control the voltage (the ships rated voltage), the electromagnetic force to overcome the reaction force of the spring and the armature is attracted to the static core, driven by the main contact is closed, on the consequent action of the circuit, the auxiliary contacts. Technical parameters 1. Products comply with IEC60947, BS5424 and GB14048.4-2003, and other standards. Main performance are shown in Table 23. Life are shown in Table 24. Auxiliary contact technical parameters are shown in Table 15. Contactor rated control supply voltage Us standard value of exchange 50Hz36V, 127V, 220V, 380V contactor rated supply voltage range of 85% -110% of the thermal state can be reliably pull, release voltage in the range of 20% -75% of Beijing, Tianjin, Shanghai, Chongqing.
