About Xi'an VS1-12 hand cart type vacuum circuit breaker of the products is the high-pressure switch apparatus of indoor, suitable for the nominal voltage 12kV, three-phase electric system of the frequency 50Hz, serve as protection and control circuit apparatus, because the special superiority of the vacuum circuit breaker, the place that is especially suitable for frequently operating. Have high reliability, safety, has long performance life, low propulsion power, higher technological characteristic of cost performance simple in construction, can meet the requirement for safe stable operation of electric wire netting. Type and meaningXi'an VS1-12 hand cart type vacuum circuit breaker service conditions ambient temperature is not higher than +40 ¡æ, not lower than & mdash; 15 ¡æ(allow the warehousing and transportation in - 30 ¡æ) ; The height above sea level is less than 1000m; Relative temperature: Japan's mean value is not greater than 95%, monthly mean value is not greater than 90%, the mean value on day of the saturated vapor pressure is not greater than 2.2& times; 10 Mpa, mean value is not greater than 1.8& times; 10 Mpa; The heat degree of the earthquake does not exceed 8 degrees; Without fire, explosion hazard, filthy seriously, chemical corrosion and place shaken vigorously. Main technical parameterMatched middle sealing-in type pottery or vaccum arc chute of glass of circuit breaker of overall structure of Xi'an VS1-12 hand cart type vacuum circuit breaker, adopt the copper-chromium contact material, the stylus structure of the cup-like vertical magnetic field, the electricity in its stylus abrades the low speed, the electricity is longe-lived, the withstand voltage of the stylus is competent, the medium insulating strength is steady, resume fast after arc, dam the horizontal bottom, the ability of gap is strong. Form in which the overall structure of the circuit breaker assigns in front and at the back of adopting operating mechanism and arc chute, the electric loop part of leading factor is the three-phase console model structure, the vaccum arc chute is installed in a tubular insulating cylinder longitudinally, the insulating cylinder is adopted APG craft to pour by the epoxy resin, therefore it especially resisted the creepage. This kind of constructional design reduces the dust to build up on the surface of arc chute greatly, not merely can prevent the vaccum arc chute from being damaged by the external factor, and can guarantee even can also demonstrate the high impedance state to voltage effect under the damp and hot and serious filthy environment.
The main loop current route when being in the position of switching-in of circuit breaker: On that wire base is fix on arc chute without being appeared get by arc chute fixed contacts internals vaccum upper bracket 27, the electric conduction by moving contact and connection is inserted, flexible joint, to the lower carriage, play the wire base out. Kept in touch by manipulation motion and maintenance stylus that the insulating draw bar finish the circuit breaker through the connecting rod system of circuit breaker with the internal dished spring 33.
Every electric current grade contains the dustproof insulating barrel cover, needn't remove when the rated current 1250A and the following grade in in-service use runs when the circuit breaker is dispatched from the factory, the rated current 1600A and the runtime of the above grade must be removed.
