Precautions for the selection of Schneider molded case circuit breaker

There are many novices who are not familiar with the fake load when repairing the inverter, and the repair of the inverter saves many of their modules with the false load, because the novice repairer generally does not know how to do this, and now the light is on to make it clear that the module is going to be broken. A false load is a resistor with a few hundred ohms ( ...

A frequency converter is a device that converts power to other frequencies of power supply. The power frequency of our country is 50Hz, in the field of motors, in order to change the speed of the motor, or other performance changes, many motors choose inverter power supply. The inverter is a supporting operation with the inverter motor.

First, calculate the value of the current of each branch (1) Purely resistive loads, such as bulbs, electric heaters, etc., are directly divided by the indicated power by voltage, that is, the formula I = power/220v; For example, a 20w bulb, branch current I=20W/220=0.09A electric air ...

When the inverter is used to form an automatic control system for control, in many cases, the PLC and the inverter are used together, and how to correctly connect the PLC and the inverter together has become the key to the success of the system. 1.PLC switch ...

a. Output frequency scale. The output frequency scale that can be controlled by the general inverter is generally 0.1Hz, and the highest frequency is different according to the functional indicators of the inverter, generally 400Hz, and some models are 650Hz. No matter how high the output frequency is, it belongs to the scale of high-frequency inverter. ...

The type of Schneider inverter generally reflects the rated voltage, rated power, and load requirements of the inverter (heavy or light load). Here are two examples: Example 1: Schneider Inverter Type: ATV71HD11N ...

1. Selection of detection diode Point-contact germanium diodes are generally used for detection diodes, such as 2AP series. When selecting, the detection diode with high operating frequency, small reverse current and large forward current should be selected according to the specific requirements of the circuit. Although the detection and rectification of ...

In appearance, mechanical ...

(1) Insulating pads should be arranged in the maintenance channel of the battery pack. (2) It is strictly forbidden to use batteries of different manufacturers, different capacities and different models in the same system. (3) VRLA batteries do not need to be charged for the first time before use, but should be recharged. Replenish the charge ...

1. Defective device If the lead wire of each pile head is not firmly connected and loosened for a long time, it will cause the pile to heat and oxidize, burn out the outer insulation of the wire, and announce sparks and burnt smell, resulting in undervoltage of the line and air switch action. 2. Leakage switch with ...

1. Insist that the air is moist or unclean, and the pipes are not clean, which may have the following consequences: (1) The wet gas is decomposed into mixed gases such as hydrogen and oxygen under the effect of arcing, destroying the insulation between the fractures after the main contact is broken, which is difficult to arc or arc re-ignition, and in severe cases, arc extinguishing will be formed.
