If the zero line of Delixi's air switch is reversed to the front, there is not much obstacle to the 2P circuit breaker and 2P leakage circuit breaker. The only effect is that it looks irregular, and you need to find the zero line from scratch when repairing, which brings a little inconvenience.
When Delixi electric circuit breaker 1P+n circuit breaker and 1P leakage circuit breaker are disconnected, only the front can be disconnected - that is, the line connected to the unsigned terminal. If the neutral line is connected incorrectly, when the circuit breaker is disconnected, the neutral line is disconnected. Even though there is no current in the circuit at the moment, there is still voltage at the moment. If a person touches it, it will still be electrocuted.
The neutral line of the 1P circuit breaker is on the neutral line row, which is not easy to connect incorrectly. The result of the wrong connection of the 1P circuit breaker is the same as the result of the reverse connection of the zero line of the 1P+n circuit breaker.

The cause of the abnormality of the motor controlled by the inverter
The first method is that you can analyze what the cause is according to the condition displayed on the inverter, such as whether the faulty code appears normal, whether there is still running code or not, and still nothing appears (in the case of input power), which means that there is a rectification problem. If you're on standby...

The change of frequency conversion control mode - Delixi inverter
In the process of practical speed regulation, an ordinary frequency-adjustable communication power supply can not meet the requirements of speed regulation and control of asynchronous motors, and must also take into account the effective use of the motor magnetic field, the suppression of the starting current and the acquisition of the desired torque characteristics, such as low-frequency torque characteristics.

The reason for the whitening of the copper bar installed on the Delixi plastic case circuit breaker
In the project, because of the 630 A circuit breaker wiring bar in the 500 kVA box-type transformer, see the second circuit breaker and circuit breaker on the left in the figure. The temperature of this corresponding region is significantly higher than that of the other two corresponding regions, and the other two phases are also hot, and the copper bars of this phase have turned white. There is no induction Deli ...
