(1) Tripping
LS electric molded case circuit breaker basically involves the tripping unit in the process of practical application, and the tripping is generally a thermomagnetic tripping or electronic tripping, and we must also understand this different tripping method in advance.
In the process of practical application, if there are requirements for the capacity of LS electric molded case circuit breakers, you can choose some special molded case circuit breaker types, Let's also understand the price of molded case circuit breakers, because of the molded case circuit breaker if it chooses different tripping methods, its price will be very different, we must understand at the time of acquisition, manufacturers in terms of detailed price rules, in addition to understanding the practical working conditions of molded case circuit breakers, Due to the practical application of the molded case circuit breaker, it will also have certain requirements for the ambient air temperature.
(2) Temperature
If the temperature is too high or too low, it may have a bad impact on the molded case circuit breaker, Now, the working conditions of the molded case circuit breaker generally require that the high temperature cannot exceed 40 degrees, and the low temperature cannot be lower than minus 5 degrees.
We must consult the manufacturer about the upper and lower limits of the temperature of the molded case circuit breaker in the practical application process, some times the price of the product supplied by a manufacturer may be relatively low, we will feel that this thing is very cost-effective, but if you deepen your understanding, you will find that its practical application process on the working conditions of the requirements are more stringent, so this will also affect the later use, we should also be particularly aware of this problem in the process of use

Servo drives and servo motors – LS produces electricity
Driver: Under the premise of carrying out frequency conversion skills, the servo drive has carried out more advanced control skills and algorithm operations than general frequency conversion in the current ring, speed ring and azimuth ring inside the drive (the frequency converter does not have this ring), and it is much stronger than the traditional servo in terms of function.

The matrix alternating control mode of the inverter - LS power generation
VVVF frequency conversion, vector control frequency conversion, and direct torque control frequency conversion are all one of the AC-DC-AC frequency conversion. One of the disadvantages is that the input power factor is low, the harmonic current is large, the DC circuit needs a large energy storage capacitor, and the regenerative energy cannot be reflected back to the grid, that is, it cannot carry out four-quadrant operation.

The difference between input reactor and output reactor – LS produces electricity
The rectifier part of the general inverter selects the diode uncontrollable bridge rectifier circuit, and the middle filter part selects the large capacitor as the filter, so the input current of the rectifier is actually the charging current of the capacitor, and the harmonic component is relatively steep and steep.

Inverter switching power supply circuit vein - LS power generation
1. Vibration circuit: the drainage-source and R4 of the main winding N1 and Q1 of the switching transformer are the channels for the working current of the power supply; R1 provides the starting current; The self-powered windings N2, D1, and C1 constitute the power supply voltage of the vibrating chip. The normal operation of these three links is the prerequisite for the power supply to vibrate.
