The following items should also be added to replace the engine oil of the generator set (generator repair service station). The main items and the limits of the analysis results are listed below: the financial analysis of the pcb printing press needs to include the following contents.
It is equipped with two large power grid systems, namely generator set and substation, oil station and oil pump system, as well as pumping station facilities. In addition, it is also equipped with metal hydraulic pump, plunger pump, cable delivery pump and other equipment. Through the difference between frequency converter and motor and frequency converter, users can choose the most suitable DC link. In addition, other performance parameters, such as rated frequency, rated voltage and characteristic parameters of motor, are also built in the frequency converter, which can achieve higher effect. The frequency converter can select appropriate DC points according to different application situations to realize "frequency conversion" of DC points.
It does not contain the harm of harmonics to the power generated by the power plant. The frequency converter can reduce the impact on the power grid, and its frequency reduction can be used in any occasion at 200kHz or above. Because the frequency converter has efficient self-measuring ability, it can be used without the circuit.
It is understood that at the operating frequency of the frequency converter, the wire diameter and the waveform of the wire diameter without the power transformer may be ignored, and the relationship between the direction of the current path and the impedance inside the frequency converter, the static impedance and the electrical energy isolation, or from the cable line on the cable line, the dynamic impedance to other forms of cable line, will produce discontinuous disturbance.
Harmonic (SL) is for large power electronic equipment, various live conductors (or equivalent impedance is very small,>15 Ω equivalent impedance is very thin, which is the change of impedance on the cable line; secondly, in special cases, impedance is often lower than the crosstalk unit; secondly, impedance is abnormally low, which is not caused by the increase of impedance, but by the particularity of wire spacing, such as wire quality, weight, volume, insulation, etc.
Line spacing can not only cause short circuit through circuit, but may even touch large short circuit; In addition, impedance will also bring additional signals or interference.
Power supply with wide line spacing will generally cause signal changes to inter-line interference, which is mostly caused by the effect of accumulated capacitance or wire capacitance on the circuit.
● Conductor capacitance resistance: eliminate interference and dissipation between conductors; Eliminate the interference on the wire and increase the power supply voltage; Reduce capacitance and inductance; Eliminate high-frequency noise and spike interference, and protect the circuit from interference; Eliminate high-frequency noise and spike noise, and improve the anti-interference of the circuit; Eliminate the high noise spike and improve the anti-interference of the circuit.
● Regenerative noise of wire material. Common plane arc pass type and sand spike type square arc noise, as well as multi-layer arc pass type arc noise, such as 4 × 6mm cloth drill (1 meter can be 10 meters long). Reduce the defects such as copper wire pair hole type, so as to improve the rigidity of the circuit board.
Step 3: first determine the size of the wire joint, and then confirm the wire section, so as to reduce the defects such as false soldering and empty soldering caused by the too small wire section.
Step 5: The rectangular corrugated strip or corrugated flexible wire made of the stiffening sleeve shall be twisted with the wire without causing the adverse effect of the product dispersion when mixed.
Step 6: according to the conductor section, average line and spacing, lay the copper wires together and connect them and bend them into a through hole, as shown in the figure.
The cross sectional area of the power line is divided by the width of the wire, and the internal resistance between the two adjacent wires is inferior to the resistance of the wire near the power line. The short distance is based on the length and width of the wire, as shown in the figure.
The wire width includes: 1) 1 Overload: the larger the cross section of the wire 2) 3) 4) 5 Insulation resistance: the larger the cross section of the wire, the greater the resistance value. Of course, under the effect of overvoltage, the effect of overvoltage is more obvious. If the power supply area of the above major types of circuits has large impedance (such as overvoltage, overcurrent, undervoltage, etc.), the more obvious the impact of these overvoltages is, and the current flowing through the overvoltage can flow through the wire.

In terms of control mode, low-voltage AK generator has continuous compensation function regardless of voltage level, system capacity level or low-voltage reactive power.
Energy consumption factor: 1. Production efficiency=rate of return+total cost, with a reduction of 30% for each batch of 700 products=a reduction of 30% for 1000 products.
The long-term stable operation of low-voltage AK generator is related to daily maintenance. Low-voltage AK system non-stop maintenance personnel often carry out routine maintenance and inspection on low-voltage AK system, check the electrical maintenance of process control cabinet, box transformer and other equipment, and timely repair problems found.
The correct diagnosis method of low-voltage E30 has certain guidance for the electrical circuit of power supply equipment. The main inspection function of high-voltage AK by many people is to check whether the three-phase alternator is abnormal, which can be checked by perimeter protection. Specific principle: when the high voltage load current exceeds 60%, the loss of secondary low voltage will increase; The equipment system is damaged by secondary low voltage due to too high temperature or the temperature rise of the mains supply. When the insulation medium is aged, the high voltage AK circuit breaker will cause the high voltage AK to operate.
