380 with 0 5 kW motor jumps about 10 seconds after starting, what s going on?

The 380 kilowatt motor trips in about ten seconds after it starts, which means that the way it starts is not in accordance with the regulations, so its wattage is also not in accordance with the regulations.

The 380 volt motor with kilowatts starts, and the power jumps in about ten seconds, first check whether the line has a short circuit or grounding.

If this is often tripped, it may be overloaded, right? Or there is a short circuit.

Check whether the motor is overloaded, or the power switch and protection device are too small.

Check that the junction box, terminal block and load line are loose or the wire is broken, and the insulation is broken.

380 large. Kw. After the elevator starts.

Ten seconds or so. Trip. What's going on?

This is. Electricity. Ito-colored taste.

Technology. Failure issues. Inquiries are available.

Relate. Specialists and technicians in electrical appliances.

When the motor starts, jumping left and right must be out of phase, check if your power supply is out of phase? If you don't have a phase, you will have this kind of jitter.

About 10 seconds after starting, the jump cut means that the working state is still unstable. And the kilowatts may be lower.

For a kilowatt motor, its power is not large, but it can trip, which indicates that there is a short circuit to the ground inside the electrode.

How do you jump to two weeks of photos? When the money is in place, the power of the left and right is not the same, that is, the power is not equal.

What are the reasons why the motor trips after 10 seconds of starting? How to become a master of automation From my point of view, let's talk about domestic automation. Prospects for the integration of PLC and DCS systems Special Operations Operations in the People's Republic of China. Discuss.

The most fundamental reason for this situation may be that the rated voltage of the motor needs to be 220 volts, not 380 volts or 380 volts, which is not a stable voltage.

The 380 motor with kilowatts tripped about 10 seconds after starting, indicating that there was a short circuit inside.

kilowatts, the motor jumps about ten seconds after starting, which is not asked.

The 80 belt kilowatt motor tripped about ten seconds after starting, that is, the electric voltage was too small and overloaded.

Dear, hello, the 45 kilowatt group shirt motor Dafan to 80 or pure 85 jumped because the motor overload protection device played a role, and the motor was overloaded. Motor overload protection device is an important device to ensure the normal operation of the motor, when the motor is subjected to excessive load, the overload protection device will automatically trip to protect the motor from damage. In this case, it is necessary to check the load of the motor to see if the rated load of the motor is exceeded.

If the load condition is normal, then it is necessary to check the insulation of the motor, whether the power supply voltage is stable, etc., to determine the cause of tripping, and deal with it accordingly. The motor is an indispensable power source in modern industrial production, and its normal operation is of great significance to ensure production efficiency and quality. In the process of using the motor, it is necessary to pay attention to the load of the motor, maintain the insulation performance of the motor, ensure the stability of the power supply and other issues to ensure the normal operation of the motor.

At the same time, it is also necessary to regularly inspect and maintain the motor, eliminate faults in time, and ensure the long-term stable operation of the motor. I hope mine can help you, oh, and I wish you a happy life

Summary. 1. The main circuit or control circuit is not electric or the circuit is not connected. Workaround:

Check the line and troubleshoot. 2. Poor contact of auxiliary contact. Workaround:

Trim or replace the auxiliary contacts. 3. The power supply voltage is too low. Workaround:

Turn up the power supply voltage. 4. The setting value of the thermal overload relay is too small. Workaround:

Increase the setting value, and after normal operation, adjust the setting value to the rated value of the motor. 2. Fault phenomenon: the contactor contact burns out quickly.

1. The main circuit or the control orange preparation circuit has no electricity or the circular calling circuit is not passable. Solution: Check the line and troubleshoot.

2. Poor contact of auxiliary contact. Solution: Trim or replace the auxiliary contacts.

3. The power supply voltage is too low. Solution: Turn up the power supply voltage.

4. The setting value of the thermal overload relay is too small. Solution: Increase the setting value, and adjust the setting value to the rated value of the motor after normal operation.

2. Fault chain drying phenomenon: the contactor contact burns out quickly.

Analysis reasons: 1. The power supply voltage of the control sensitive head is low, and the contact runout causes burnout. Workaround:

Turn up the power supply voltage. 2. Short circuit on the load side. Workaround:

Check the line and troubleshoot. 3. The contact spring is annealed or damaged, and the contact overtravel is too small. Workaround:

Replace accessories or contactors. 3. Bridge number fault phenomenon: the hot overload relay does not operate after the overload is found

1. The setting value of the thermal overload relay is much greater than the rated value of the motor. Solution: Readjust the setting value of the thermal overload relay.

2. The thermal overload relay is damaged. Solution: Replace the thermal overload relay.
