Delixi E series inverter common fault analysis

Regulator problem 1: The regulator cannot be started Reason: Whether the phase sequence of the input power cord has been changed, and the air switch in the machine is not turned on or broken. Repair methods: 1. Swap the two power supply wires arbitrarily or check whether the power supply line is correct; 2. Close or replace the switch. Voltage Regulator ...

　　The principle and operation method of Delixi inverter: 1. No-load energizing test of inverter 1. Ground the grounding terminal of the inverter. 2. Pass the power input terminal of the inverter through the leakage maintenance switch.

1. Failure analysis. 1) Closing fuse, control fuse blowing or poor contact. 2) Poor contact of DC contactor or poor contact of control switch contact and auxiliary contact of circuit breaker. 3) The DC voltage is too low. 4) Closing and locking action. ...

1. The device of the inverter 1.1 The device environment requirements of the inverter Ambient temperature - 10 °C - 40 °C; Ambient humidity: The relative humidity does not exceed 90% (no condensation); Other occasions requiring no direct sunlight, no corrosive gas and flammable gas, less dust, ...

Delixi's control transformer is one of the products used in many equipment, the type of Delixi transformer is divided into: BK, JBK, BKC, JMB, BJZ, DG, BZ and other series of control lighting transformers, with excellent performance, reliable work, wide applicability and other characteristics, generally used in machine tools, mechanical ...

The switching voltage regulator is a different kind of regulated power supply from the linear voltage regulator, and its circuit types mainly include single-ended flyback, single-ended forward, half-bridge, push-pull and full-bridge. The difference between it and the linear power supply is that the transformer in the circuit does not work at the power frequency, but at the power frequency.

Delixi's three-phase circuit breaker is generally divided into three types, namely 3P, 3P+N and 4P. (1) Differences: 3P: Pure three-phase electrical equipment only uses three wirings, and in the case of no single-phase load, it trips when it is short circuited to ground or phase; Otherwise, when a one-phase N-line load is generated, the N-line is disconnected ...

1. Repair the damage of the inverter rectifier block The damage of the inverter rectifier bridge is also one of the common faults of the inverter, the inverter rectifier block produced in the early stage is mainly diode rectification, and now some rectifier blocks adopt the thyristor rectification method (voltage regulation and frequency modulation inverter). Middle...

Delixi general fan, pump, the requirements for the inverter are simple, only the inverter capacity is equal to the motor capacity. Roots blowers, deep-water pumps, sediment pumps, and fast-changing musical fountains are available in a larger capacity. Lifting...

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: ...

1. There is a problem with a frequency converter, it cannot operate and the LED shows "UV" (abbreviation of under voltage), which clarifies that the alarm in the book is DC bus undervoltage. Since the control loop power supply of this type of inverter is not taken from the DC bus, but from the communication input through the transformer alone...

1. Ability to adapt to the environment When the motor on the bus starts in a group, when the bus is the largest motor unit starts, the impact on the operation of the inverter, which is related to the input voltage fluctuation scale parameters promised by the inverter, for thermal power units should ensure that the bus voltage drops by 30% when the frequency conversion ...

Delixi Group focuses on low-voltage power distribution and industrial automation in the field of comprehensive solutions suppliers, founded in 1984, is a collection of industrial operations, brand operations, capital operations as one of the large enterprise groups, for 18 consecutive years ranked among the top 500 Chinese enterprises. Delixi rangefinder is designed for ...

Most modern LDOs and switching regulators operate reliably under no-load conditions, and some older power devices require a minimum load to ensure stability, because one of the electrodes that needs to be compensated is affected by the payload resistance. For example, the LM1117 requires a load current of at least 1.7 mA (most ...

Thermal relay is a maintenance appliance used for overload maintenance of electric motors or other electrical equipment and electrical lines. In the actual operation of the motor, if the machine is in abnormal condition or the circuit is abnormal, the motor will be overloaded, the motor ...

The essence of energy feedback is active inverter, and the energy feedback of the general inverter is completed by the reverse parallel three-phase inverter at the uncontrolled rectification of the pre-stage of the general inverter, and the regenerative energy is fed to the power grid. The main circuit of the energy feedback equipment is mainly composed of thyristors, IGBTs and IPM modules.

1. The output power of Delixi voltage regulator is the maximum power Basically, most of the nominal power of household appliances refers to active power, and the so-called refrigerators, air conditioners and those water pumps used in the home, etc., most of them are also rational loads that start instantaneous currents.

The primary effect of Delixi voltage regulator is, of course, to stabilize the voltage. When the grid voltage fluctuates instantaneously, the regulated power supply will compensate for the voltage amplitude with a response speed of 10-30ms 1. Stable voltage: Wangwen Shengyi, Delixi stabilizes ...

1. The quality of the socket is low First of all, we should check whether the socket is a miscellaneous defective product, the copper clamping force in the defective socket is not enough, resulting in a poor connection between the socket and the plug, and the socket and plug will heat up after a long time of electrical use. Therefore, you must not buy cheap miscellaneous electric ...
