Basic terms breaker points by mode of operation: electric operations, storage operations and manual operation; by the structure: there are universal type and shell type; by using the category: selective and non-selective; divided by arc media : There are oil-immersed, Vacuum and air; by the movement speed points: a fast and Normal; divided by the number of poles: unipolar, two-pole, three-pole and four-pole, etc; according to the installation points: insert type, such as fixed and drawer. Xian Huayi power plant is the backbone of high-voltage electrical equipment companies Panzhihua Which high-voltage vacuum circuit breakers, leading products 6-110kV voltage vacuum circuit breaker, low voltage switch cabinet, box-type substation, power transformers, voltage and current transformers , high-voltage fuse, load switch, disconnecting switch, zinc oxide surge arresters, harmonic elimination, wall bushing, post insulators, high voltage SF6 circuit breakers, transformers neutral point discharge gap and spare parts, such as vacuum circuit breaker, breaker External accessory electric operation: This is an accessory for a remote automatic opening and closing of the circuit breaker operating mechanism has two electric motors and solenoids operating mechanism operating mechanism, motor operator for Molded Case breaker frame degree above the rated current 400A breaker, solenoid-operated mechanism and apply MCCB frame degree rated current 225A and below the circuit breaker, either solenoid or motor voltage vacuum circuit breaker Suining Which is good, they The pull and rotational direction is the same, only the internal position of the cam motor operating mechanism to achieve together, divide the circuit breaker when the electric mechanism operating between 85% -110% of the rated voltage of either control voltage, circuit breakers should be able to ensure a reliable closure. Turn the operating handle: for molded case circuit breakers in the breaker operating handle cover mounted rotating body. Long Handle: is an external extension handle, directly mounted on the handle of the circuit breaker. Suining high voltage vacuum circuit breakers, vacuum circuit breakers, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
