Delixi inverter fault maintenance

1. Although the air switch is a type of circuit breaker, it is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. However, air switches are used in low-voltage distribution networks and electric traction systems, mostly on the low-voltage side. Widely used in the home, such as general household switches ...

S1 (Single-phase 110V, 50/60HZ) CDI-EM60G0R75S1 0.75KW CDI-EM60G1R5S1 1.5KW S2 (Single Phase 220V, 50/60HZ) CDI-EM60G0R4S2 (without built-in brake unit) 0.4KW CDI-EM60G0R4S2B (Built-in ...

1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the working current balance in the zero sequence current transformer and causes the leakage protector to malfunction. If you want to use the neutral line of the power branch line as the neutral line of the lighting branch line nearby, it will cause the leakage of the power branch line.

Typically, every electrical device or device is designed for a wide range of input voltages. Depending on the sensitivity, the operating scale of the device is constrained to a specific value, for example, some devices can tolerate ±10% of the additional voltage, while others can tolerate ±5% or less. ...

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...

1. Check and tighten all terminals to prevent serious heating caused by loosening. 2. Conduct a comprehensive view of the input (including output) terminal, rectifier module, inverter module, DC capacitor and fast-melting devices, and the parameters ...

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: ...

In most large electrical systems, generators and power transformers are the two most expensive pieces of equipment. In addition to the capital cost of purchase, the continuity and reliable operation of these two key equipment systems are also the most critical. For example, the test ...

CDB1 miniature circuit breaker is a current-limiting high-breaking miniature circuit breaker with overload and short-circuit two-layer maintenance, which is suitable for communicating 50Hz, additional voltage 400V and below, and additional current 63A and below circuits.

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 ...

The spring is a widely used component in the circuit breaker mechanism, and the critical spring has a great impact on the function of the circuit breaker. From the perspective of energy, combined with the installation space of the tension spring, the author uses the existing accounting formula of the tension spring to solve the unknown quantity from the known quantity to obtain the required tension spring parameters.

A four-quadrant power supply is a power supply capable of absorbing and supplying positive and negative currents and voltages. While a simple voltage converter is capable of generating a fixed output voltage from the input voltage, this feature is not sufficient in some applications. An example is the control of voltage nodes connected to capacitors that ...

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.

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

On January 27, the "4th China Electrical Appliance Culture Festival and World Electrical Products Expo" was grandly opened in Liushi, Wenzhou, the capital of China's electrical appliances. More than 500 companies from home and abroad showed their faces on more than 1,400 booths. The largest Delixi exhibition hall with a booth area of more than 1,800 square meters ...

The function of Delixi circuit breaker is to make the circuit breaker internal electromagnetic tripping when the electrical equipment produces short circuit, overload, etc., resulting in the circuit breaker disconnecting the power supply, and maintaining the safety of electrical equipment and personnel. When the electrical equipment is running, the circuit may produce abnormalities, which is the demand circuit breaker in the ...

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. ...

1. Check the time first, if the time of the week, hour and minute is correct, don't care. If it's not correct, you need to take care of it yourself. Conditioning is very simple, you just need to press the clock, and then adjust the week by week, the hour of conditioning, and the minutes of conditioning. ...

Thermal accounting requires information such as power loss, thermal resistance of the package, and ambient temperature. The power loss is calculated in the same way as the efficiency accounting, which is simply the value of the difference between the output input voltage and the input current. Thermal resistance should have a technical standard documented, and if it is not available, it is necessary to consult the manufacturer. Basically...

When the Delixi voltage regulator is turned on, the voltmeter does not indicate the problem phenomenon and cause analysis 1. The plug is not plugged in firmly, and there is no output voltage 2. The fuse is broken When the Delixi voltage regulator is turned on, the voltmeter does not indicate the problem is solved ...
