The cell-sensitive varistor of the Shanghai Linked Console is an unconfix electromagnetic element, which is equivalent to an equivalent impedance. The resistor is an important part of the Shanghai Linked Console. There are many kinds of resistors on the market. Because we don’t know the correct way to select the resistor, this has a certain difficulty in purchasing resistors.
1. The frequency-sensor start current is too large (greater than 2.5 times), the startup is too fast, the number of increases can be increased, and the tap is received to 100% turns, and the effect makes the start current decrease, the start torque is reduced.
2, the frequency-sensor start current is too small (less than 2 times) the starting force torque is not enough, the startup is too slow, the number of times can be reduced, the tap is received by 80%, the effect makes the start current increase, the start torque increases .
3. If the machine is restarted after a while, when there is a mechanical load, it is difficult to start again, and the motor can be used for a few times, so that the mechanical rotation will be used normally.
Understanding the restrictions of the frequency-sensitive varistor startup, there are special circumstances to ensure the qualification rate of our products.
The resistor of the Shanghai Linked Console is a current limiting element that will limit the electrical blocking in the circuit, which can limit the current size of the branch it. Today, let’s take a look at whether the resistors of the linkage console are damaged.
If a resistor has an infinite or large resistance, the loop of the resistor can be viewed as an open circuit, and the current is zero. The resistor commonly used in the industry is between two extreme conditions, which has a certain resistance, which can be largely used by a certain current, but the current is not as large as a short circuit. Restricted limiting effects of resistors are similar to the active flow of small diameter tubes between two large diameter pipes.
The linear resistance of the linkage console is generally used as a large current limit, and the resistance is not large. When the cylindrical wire is burned down from the electric resistance, there will be black or surface burst, cracks, and some have no traces.
The resistor of the linkage console is a current limiting element, and it can limit the current size of the branches through the electrically blocking the circuit. If the resistance value of a resistor is close to zero ohm, the resistor does not hinder the current, and the circuit of this resistor is short-circuited, and the current is infinite.
If a resistor has an infinite or large resistance, the loop of the resistor can be viewed as an open circuit, and the current is zero. The resistor commonly used in the industry is between two extreme conditions, which has a certain resistance, which can be largely used by a certain current, but the current is not as large as a short circuit. Restricted limiting effects of resistors are similar to the active flow of small diameter tubes between two large diameter pipes.
So how is the linkage console resistor to limit the limit, and the partial pressure effectively reduces the input voltage of the electrical appliance, R2 is a current limit, according to the size of the R2, can control the current of the electrical appliance, and the partial pressure is to be connected in series, limited to the target device. The flow is to go parallel with the target device.
