"High-voltage vacuum circuit breaker characteristics: ① contact opening distance small, 10KV vacuum circuit breaker contact opening distance is only about 10mm, operating power operating mechanism is small, small mechanical part of the trip, its mechanical life is long ② arcing time. short, and has nothing to do with the switch current size, generally only half cycle after the contact gap ③ extinguishing media recovery faster, better off breaking performance near fault zone. ④ due to dredge at the breaking current small amount of wear, so long electrical life contact, full capacity breaking up 30-50 times the rated current of more than 5000 times breaking vacuum breaker accompany you through 2014, low noise suitable for frequent operation. ⑤ small size and light weight. ⑥ applicable in breaking the capacitive load current circuit breakers are welcome to inquire to buy an external accessory electric operation:! This is an accessory for a remote automatic opening and closing of the circuit breaker, electric operation and electric motor operating mechanism Two solenoid operating mechanism, motor operator for MCCB 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 solenoids or motors, they 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 at the rated voltage control 85% -110 either voltage% between breaker should be able to ensure reliable operation of the closing rotation handle: suitable for molded case circuit breakers, installed in the cover of the rotation mechanism of the circuit breaker operating handle, the handle shaft fitted with holes in its body the other end of the door opening, the shaft passing through the drawer cabinet, the rotary knob mounted on the handle of the exposed above the door sets of apparatus of the spindle head, the handle round or square base with screws in the door, such a mounting enables The operator at the door handle through the handle clockwise or counterclockwise rotation, to ensure that the closing or opening of the circuit breaker while turning the handle to ensure that when the circuit breaker is a vacuum circuit breaker closing, the door can not be opened; only turn the handle in the opening or re-buckle, switch board doors to open. In case of emergency, the circuit breaker in the "closing" and need to open the door vacuum circuit breaker with you forever, you can press the red release button on the handle to rotate the seat edge . Long Handle: is an external extension handle, directly mounted on the handle of the circuit breaker, generally used on 600A and above high-capacity circuit breaker operating handle to manually open and close the locking device: the handle is mounted on the frame vacuum breaker purchase cards, punched the handle and then locked up with a padlock is mainly used in the closing circuit breaker when working condition, do not allow other people opening and cause blackouts, or load side of the circuit breaker needs to be repaired or When electricity is not allowed, to avoid being accidentally closing the circuit breaker to protect the safety of maintenance personnel and reliable use of electrical equipment or vacuum breaker buy, Hanzhong vacuum circuit breakers, Huayi Huayi electricity from the power plant in Xi'an provided Xi'an 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!
