Delixi's three-phase circuit breaker is generally divided into three types, namely 3P, 3P+N and 4P. (1) Differences: 3P: Only three wirings are used for pure three-phase electrical equipment, which trips when there is no single-phase load to the ground or when there is a short circuit between phases; Otherwise, when a one-phase N-line load occurs, the N-line is disconnected ...

1. When using a multimeter ohm, remember not to measure with electricity. 2. When using the logic pen and oscilloscope to detect the signal, it is necessary to pay attention not to make the probe contact the two measurement pins together, because the essence of this situation is to constitute a short circuit in the case of power-on. 3. Detect filtering in the power supply ...

1. According to the load type, confirm the type of inverter: different load types, speed requirements and power size, and the need to choose different types of Delixi inverters. Therefore, it is necessary to understand in detail the type of motor load to be controlled to find the most suitable type. ...

Among the objects of circuit breaker maintenance, there are some electrical equipment that generate several times its rated current in a short period of time during the start-up process (1) The setting of the operating current of the instantaneous overcurrent tripper In the circuit breaker maintenance of ...

1. The inverter runs with the motor at no load 1. To set the power and number of poles of the motor, the operating current of the inverter should be considered. 2. Set the maximum output frequency, fundamental frequency, and torque characteristics of the inverter. The general-purpose inverter is equipped with a number of VPf curves for users to choose.

Delixi intelligent all-round circuit breaker CDW9 series, should be checked regularly every year, first open and close and long-distance equipment, successively use a variety of additives, test operation program column, control unit test using a small test suite; Every two years or when the control unit repair target reaches 100, it should be ...

Delixi Electric launched a new "product intelligence" series of products, with outstanding quality and higher cost performance of professional competitiveness, to meet the green consumption demand for low-voltage electrical appliances in the field of construction and real estate, and promote China's low-voltage electrical profession into a new green development era. This "product wisdom" ...

1. Upper frequency (high speed) SEt - HSP and lower limit frequency (low speed) SEt - LSP The upper frequency is the frequency corresponding to the *** large given, and the lower frequency is the frequency corresponding to the *** small given. The upper and lower limit frequencies are set to limit the speed of the motor, so as to satisfy the design.

1. Superior performance The new vector control algorithm is adopted, and the starting cabinet is large, the torque response is fast, and the control accuracy is high, which further improves the operation efficiency of the motor. 2. Powerful function and low cost of use Built-in large number of ...

Grounding current, also become quiescent current, load regulation (the smaller this value, the stronger the LDO can press the load) linear regulation (the smaller, the less influence of the input voltage on the output voltage, the better the LDO function) power supply ratio (PSSR), reflecting the Delixi LDO to the interference signal ...

In view of the regulation and control effect of the transformer in the power system, technicians need to choose the appropriate transformer finishing device operation, so as to play a normal effect. Winding data is the primary problem that transformer devices need to pay attention to, and the effects of devices of different materials are different. Concerning...

Application of air switches (circuit breakers). Delixi air switch, also known as circuit breaker. It is a switch that actively closes as soon as the current in the circuit exceeds the additional current. Air switch is a very important electrical appliance in the low-voltage distribution network and electric traction system.

1. Pay attention to the maximum value of output current: this is a very critical parameter, the current used exceeds the maximum output current of LDO, then the voltage is unstable, and the system will fail. LDO limit parameters: The output current is considered according to the 2/3 criterion. The cost of the whole system ...

1. Motor encoder alarm 1. The cause of the failure (1) Wrong wiring; (2) electromagnetic disturbance; (3) Encoder hardware damage caused by mechanical vibration; (4) Pollution caused by the on-site environment. 2 ...

The main circuit is the power conversion part that supplies the voltage regulation and frequency modulation power supply to the asynchronous motor, and the main circuit of the inverter can be roughly divided into two categories: the voltage type is the inverter that converts the DC of the voltage source into a communication inverter, and the filter of the DC loop is the capacitor. The current type is to convert the DC of the current source into a communication ...

Class I refers to the circuit breaker, which is only used for maintenance and not for normal operation; The other is that circuit breakers are required together for maintenance and infrequent operation. In the latter case, the operating conditions and electrical life should be taken into account. The selection principles for circuit breakers for motor maintenance are as follows: ...

Question: Delixi inverter control motor contactor does not start when there is no action? Solution: First check the output status of the controller reflected by the controller panel, and you can compare the 7 units on the panel described in the controller description book.

1. Voltage circuit breaker problem The contact is overheated, you can smell the power distribution control cabinet, by checking that the moving contact is not completely inserted into the static contact, and the contact pressure is not enough, resulting in a decrease in the switching capacity, causing the contact to overheat. At this moment, it is necessary to adjust the operating organization so that the moving contact is completely inserted into the static contact ...

Look at the quality of the surge protector, to see whether it can complete his basic specification, relative to the surge protector of the primary specification is whether the surge operating voltage can be constrained below the required value, the surge protector must discharge the lightning current when the mission is completed, this specification must be completely completed.
