Precautions for setting parameters of Schneider inverter

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 ( ...

1. Air conditioning: It is generally forbidden to use UPS power supply, because the air conditioning is very large and belongs to the rational load. Not suitable for belt loads 2. Motor: It is necessary to choose a large-capacity UPS power supply, because it is a rational load, and it is ...

The advantages of closed busbars over open busbars are: 1) Closing the bus duct can reduce the grounding fault, avoid the short circuit between phases, basically eliminate the grounding defect caused by external moisture, dust and foreign objects, and improve the continuity of generator operation. 2) Eliminate ...

Schneider PLC series mainly includes: Schneider NEZA PLC (Schneider TSX08 series); Schneider Quantum PLC (Schneider 140 series); Schneider Micro PLC (Schneider TSX37 series); Schneider Premium PLC (Schneider TSX...

(1) Evaluate the safety control level that the machinery and equipment need to reach (2) Confirm the type of input signal to be monitored and (3) the number of input signals that need to be monitored (4) The number and type of channels that the module needs to output (5) Whether it is necessary to control the output device (such as ...

Schneider Barrier Features: First of all, Schneider Barrier Switch can be used to block the power supply, it can disconnect the live equipment from the high-voltage maintenance equipment, and it can also see a significant disconnection point on it. The second is that Schneider Barrier Switches are able to work with circuit breakers to reach the point where the operation of the system is changed.

Rotary encoder to roll the output pulse, through the counting equipment to know its position (PLC) we usually use incremental encoders, the incremental encoder output pulse signal can be directly input to the PLC, the high-speed counter of the PLC to count its pulse signal, in order to obtain the ...

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. Despite the ...

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.

1. Determine the type and maintenance situation of Schneider circuit breaker according to the maintenance requirements of the line, and determine the selection of frame type, device type or current limiting type. Generally speaking, the short-circuit current breaking ability of Schneider frame circuit breaker is larger and larger than that of device type. Usually, the branch line chooses ...

In the process of controlling the motor, the motor variable-frequency drive (VFD) may still have a certain kinetic energy when the motor rotates intermittently due to factors such as the moment of inertia of the motor, and the braking resistor is required to interrupt the motor. Here's a ...

(1) The operation circuit compares the external speed, torque and other instructions with the current and voltage signals of the detection circuit to determine the output voltage and frequency of the inverter. (2) The voltage and current detection circuit are the same as the main loop potential ...

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.

Whenever the inverter is down due to a problem, a problem code will appear. The most common causes are overcurrent, overvoltage, inverter temperature, etc. It's a good idea to find an explanatory book with specific questions to be asked about. 1. Overload jump ...

With the development of the electric power industry, now the electricity has been accompanied by every detail of our days, so the maintenance of the electric power industry, began to get more and more attention from everyone, because the circuit in the daily operation side, very simple because of overvoltage or undervoltage and present a certain problem, which ...

After the maintenance function of the inverter is caused by the operation of the problem, it will trip immediately, and the fault code will be displayed together, and the tripping alarm indication circuit of the peripheral inverter will send out an audible and visual alarm to remind the operator to clean up the problem in time. Inverter hopping ...

The function of the thermal relay is mainly used to carry out overload maintenance on the asynchronous motor, and his operating principle is that after the overload current passes through the thermal element, the bimetal sheet is heated and twisted to advance the action organization to drive the contact action, so as to disconnect the motor control circuit to realize the motor power-off thermal relay ...

1. According to the requirements of measurement intention: It is required to select the unit with instantaneous flow rate or cumulative flow rate (cumulative flow), the unit of flow display, measurement accuracy, repeatability, linearity, flow scale and scale, measurement temperature, pressure loss, temperature and pressure compensation, output signal characteristics and echoes.

The Schneider NSX molded case circuit breaker has a double rotary contact construction for maintenance, and the high-end electronic trip unit allows for accurate measurement and easy communication.
