Circuit Structural Features
The circuit breaker is composed of an operating mechanism, a conductive circuit, an insulation system, a seal and a shell. The overall structure is a three-phase box type. The operating mechanism can be equipped with a manual or electric spring operating mechanism. The break is in the arc extinguishing chamber. It has a long service life and a large breaking capacity. The circuit breaker has a built-in multi-tap current transformer for overcurrent protection. The internal and external insulation of the circuit breaker is composite insulated box with dry air inside. It has the characteristics of small size, light weight, beautiful appearance, easy operation and maintenance. On the basis of the circuit breaker body, the isolating switch body and isolation are installed into an assembled structure. The circuit breaker-isolating switch combination electrical appliance has reliable interlocking and an obvious and safe break when sectionalizing the switch. Installing a power transformer and centralized controller on this product can realize automation of power distribution protection.
After unpacking, check whether the insulation cover of the pole-mounted circuit breaker is damaged or not, 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 mechanism's closing and opening methods to conduct trial operations to check whether all indicators are correct.
Transportation, acceptance and storage
, 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 perform the following tasks
, check whether the packaging is damaged
, check whether the documents are complete and whether the accessories and spare parts are complete according to the product packing list complete.
Check whether the technical parameters and product certificate on the nameplate of the pole-mounted circuit breaker meet the order requirements.
Storage
This pole-mounted circuit breaker should be stored indoors 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 compliance.
