Factors affecting the normal operation of Ready Board With Wiring and Bulkhead

After the failure of the Ready Board With Wiring and Bulkhead, it will cause unnecessary trouble for users. According to the staff, the main causes of the failure of the Ready Board With Wiring and Bulkhead are caused by factors such as the environment and the improper selection of electrical appliances. The following Ready Board With Wiring and Bulkhead manufacturers will introduce in detail the causes of the failure of the Ready Board With Wiring and Bulkhead equipment.

The fault caused by the influence of ambient temperature on low-voltage electrical appliances. The low-voltage electrical appliances in the Ready Board With Wiring and Bulkhead are composed of leakage protection circuit breakers, miniature circuit breakers, sockets and switches. These low-voltage electrical appliances are designed and manufactured in accordance with IEC basic standard for low voltage electrical appliances, and their normal working conditions are specified accordingly: the upper limit of ambient air temperature does not exceed 40 ℃; The average value of ambient air temperature in 24h shall not exceed 35 ℃; The lower limit of ambient air temperature shall not be lower than -5 ℃ or -25 ℃.

For the fault caused by the improper selection of electrical appliances in the Ready Board With Wiring and Bulkhead, due to the improper selection of the current of the miniature circuit breaker during manufacturing, the circuit breaker with the same capacity is installed for different outgoing circuits, and the imbalance of three-phase load is not taken into account, so the current level of some outgoing circuit breakers cannot be increased by one current level on the basis of the normal selection model, As a result, some Ready Board With Wiring and Bulkheads are burnt out during the operation of Ready Board With Wiring and Bulkheads in high temperature seasons in summer.
