![]() ![]() Jcz5-12kv Vacuum Contactor AC High Voltage Vacuum Contactor The factory is located in Yueqing, the famous town for all types of low and high voltage electrical parts.It occupies square more than 10000m2, and has developed several international production l Zhejiang Volcano Electrical is a professional factory for prodcuing 10-40.5kV electrical equipments for power transmission, including all types of indoor&outdoor vacuum circuit breakers, automatic current recloser, SF6&vacuum load break switch, isolating switch, earthing switch, air&gas insulated switchgear, vacuum interrupters, fuse cutouts and lightning arresters. Earthquake intensity: ≤8 degree (as per terms UBN-97: Zone 1)ħ. Wind pressure: ≤700Pa (equals to wind speed 37.5m/s)ĥ. The index is better than similar products.Ĥ.The mechanical retaining device is self-contained, with reasonable structure and more reliable use.Ģ. At the same time, the auxiliary switch head also uses buffer to reduce the action impact force and improve the reliability of the auxiliary switch.ġ.The flexible support of the rotating shaft, no clamping force and small axial movement improve the action performance and consistency.Ģ.The reasonable action mechanism ensures the axial movement coaxiality of the vacuum tube moving conducting rod, and improves the performance and reliability of the contactor.ģ.The contact pressure of the main contact is enhanced to improve the electrical performance and action characteristics. Mature technology, reliable quality and good market reputation.ģ.The 630A current level adopts double moving end connection of end face and conductive clamp, which makes it more reliable with low resistance and low temperature rise.Ĥ.The conducting bar is beautiful and durable, and the upper end has two modes of horizontal connection or vertical connection, which is convenient for users.ġ.The unique built-in large capacity sealed auxiliary switch in similar products greatly improves the reliability and safety of auxiliary switch.Ģ.It adopts double coil electromagnetic system, and the matching characteristic with action force is better than that of single coil.ģ.The operation structure is optimized to reduce the starting power and holding power of the coil, so the temperature rise is low, the service life is long and the reliability is more.Ĥ.The limiting buffer is set at the opening limit position of the movable armature to eliminate the hidden trouble caused by the excessive rebound amplitude of the opening. The contactor complies with GB/T 14808,IEC 60470 and JB/T 7122 standard,the main performance indicators have reached the international level.ġ.The integral frame structure is adopted to ensure the insulation and provide sufficient mechanical strength at the same time.Ģ.Vacuum switch tube is made by domestic famous manufacturers. also widely used in high-voltage capacitor reactive power compensation devices. JCZ5 series is a three-phase AC 50Hz indoor high-voltage switch control equipment, suitable for rated voltage up to and including 12kV voltage grade, rated current 630A power system,to control high-voltage electrical equipment and frequent operation.often with F-C ark. The "HY5WR" type can be selected.Jcz5-12kv Vacuum Contactor AC High Voltage Vacuum Contactor ![]() The "HY2.5WD" or "Y2.5WD" type can be selected.Ĭapacitor type: Suppresses the overvoltage generated by the vacuum circuit breaker or the oil-less circuit breaker operating capacitor bank, and protects the capacitor bank from the operating overvoltage. Motor type: limit the overvoltage generated when the vacuum circuit breaker or the oil-less circuit breaker is switched to rotate the motor, and protect the rotating motor from the overvoltage of the operation. Power station type: Protect AC electrical equipment in power plants and substations from atmospheric overvoltage and operating overvoltage. The "HY5WS" metal oxide arrester should be selected. Power distribution type: The switchgear, transformer, box type, cable head and other related power distribution equipments are protected from atmospheric and operational overvoltage damage. The problem that the arrester should pay attention to when selecting the typeįirst of all, you should pay attention to the location of use, the location is different, the model of the arrester is also different. ![]()
