AB-3S-12 Xi'an 10KV permanent magnet vacuum circuit breaker

Xi'an permanent magnet vacuum circuit breaker
Overview
!-Permanent magnet vacuum circuit breaker adopts vacuum arc extinguishing principle, permanent magnet operating mechanism, and integrates microprocessing technology, modern network communication technology and new switch manufacturing materials. . The rated voltage is, three-phase AC outdoor power distribution equipment. This product is widely used as a disconnecting or contact switch in urban power grids, or as an outlet switch in outdoor substations in rural power distribution systems. It can effectively complete the dividing and closing of load currents and short-circuit currents.
!: Normal working conditions
! The upper limit value of the ambient air temperature does not exceed +, the lower limit value does not exceed -, and the hourly average temperature value does not exceed +3. The altitude of the installation site does not exceed meters.
!The relative humidity of the atmosphere does not exceed when the ambient air temperature is +, and there can be higher humidity at lower temperatures ***The monthly average of the wet month***When the lowest temperature is +, the average The relative humidity is , and takes into account the condensation that occurs on the surface of the product due to changes in humidity.
!The pollution level is level three.

!.... .....Installation, use and maintenance of three-phase permanent magnet vacuum circuit breaker.............
!
!:. After unpacking, check whether the insulation cover of the pole-mounted circuit breaker is damaged, and whether the product nameplate and certificate are consistent with the actual product.
!:. Before putting the pole-mounted circuit breaker into operation, you should carefully check whether the rated voltage and rated current of each operating component are consistent with the actual situation. And use the closing and opening methods of the mechanism to conduct trial operations to check whether all indicators are correct.
!:.3 The circuit breaker can be erected on a single pole or on double poles
!
!:. Due to its special design structure, this pole-mounted circuit breaker ensures that users can use it in the medium and long term. Maintenance free.
!:. Users are not allowed to replace or use electrical components that are inconsistent with the original model specifications.
!:. Operators should have a preliminary understanding of the performance of the mechanism and knowledge of installation, adjustment, and maintenance. Problems during operation should be recorded, and the manufacturer should be notified when necessary.
!
!.............Transportation, acceptance and storage of permanent magnet vacuum circuit breakers...... ..........
!
!.Transportation
!During transportation, the entire unit must be packed into a closed packaging box and fixed. It must not be turned over or tilted during transportation, and shockproof measures must be taken.
!.Acceptance
!After receiving the pole-mounted circuit breaker, the user should do the following:
!, Check whether the packaging is damaged
!, Check whether the documents are complete against the product packing list , accessories and spare parts are complete.
!: Check whether the technical parameters and product certificate on the nameplate of the pole-mounted circuit breaker meet the ordering requirements.
!.3 Storage
! This pole-mounted circuit breaker should be stored in a dry, ventilated, moisture-proof, shock-proof and harmful gas-proof room. For long-term storage, the environment should be checked regularly to see if it meets the requirements. Packing, unpacking and storage should be done in a dry room, and the products and components should be checked for completeness and consistency.
