The insulation resistance of the submersible pump, the absolute resistance of the submersible pump i

What do you want to know?

Insulation resistance of submersible pumps: including the resistance to the ground of each phase of three phases, the normal is 300 megaohms to infinity. The phase-to-phase resistance of two pairs of three phases is normally 300 megaohms to infinity. Detect with a shake table.

The resistance of U, V, and W, the value of the three-phase resistance should be roughly equal, if the three-phase is unbalanced, it means that there is a problem with the motor. This is detected with a multimeter or digital bridge.

The insulation resistance of the submersible pump should be greater than 50 megaohms in the cold state.

Summary. How much is the absolute image resistance of the submersible pump to be considered normal, hello dear, the absolute image resistance of the submersible pump is greater than the normal insulation resistance is not less than. If it is a new installation or overhaul, the insulation resistance of the low-pressure water pump should not be lower, and the operating one should not be less than 1000 per volt; If it is a high-pressure water pump, its insulation resistance should not be less than 1m per kilovolt operation

The insulation resistance of the submersible pump plays a role in protecting the motor for the submersible pump, which is to test the insulation between the motor rotor and the motor shell, if the insulation is unqualified, the motor is easy to enter the water, leakage, and cause damage to the motor: the wire is short-circuited, the motor can not work, so that the submersible pump can not run, and it is easy to cause injury to people. The structure of the motor part of the submersible pump has an effect on the insulation.

The sealing situation has an impact on the working efficiency of the submersible pump. The insulation resistance of the submersible pump is the withstand voltage level of the magnet wire, and the commonly used ones are 750V, 1000V, 4000V, 6000V, and 10KV. The test standards for insulation resistance values are as follows:

1. The insulation resistance of low-voltage electrical equipment after new installation or overhaul should not be less than. 2. The requirements of the line in operation can be reduced to no less than 1000 per volt. 3. The insulation resistance of the three-phase squirrel cage asynchronous motor shall not be less than the stator insulation resistance value of the three-phase wound asynchronous motor, the hot state shall be greater than that of the cold state, and the rotor insulation resistance value shall be greater than that of the cold state.

Summary. 380v submersible pump resistance how much pro, hello, glad your question. 1. Description of the resistance value of the submersible pump coil:

The resistance value of the pump coil of the same power is not the same according to other parameters, so this can not be confirmed, and it needs to be measured according to the actual situation, generally the following points affect the type of pump coil resistance pump, such as sewage pump, submersible pump, vertical or horizontal booster pump, etc.; The power supply voltage of the water pump, such as single-phase or three-phase water pump, 220V, 380V and 440V and other factors; The rated speed of the same power water pump, the rated speed of the water pump is different, then the coil resistance value is also different; The material of the pump coil, such as aluminum coil or copper coil, is different, and the resistance value will definitely not be the same. Second, the coil resistance calculation also depends on the voltage of the pump, if the voltage of the pump is three-phase 380V, the formula: p=u r, then r=u p=380 4000=ohms.

Second, the coil resistance meter wheel is delayed to see the voltage of the pump, if the voltage of the pump is three-phase 380V, the formula: P=U R, then R=U P=380 4000=Ohm.

Yes, dear. Why don't you go back.

Dear, yes. Are the three-phase resistance values all positive length motors?

The relative ground resistance of 380V three-phase motor is generally not less than megaohm, and the relative ground resistance of 6kV three-phase motor is not less than 6 megaohm. For the rated voltage of 380V motor, use 500V or 1000V shake meter (megohmmeter) to measure to the ground, greater than is considered normal (the bigger the better). The insulation resistance of the 6kV motor should be measured by 1000V-2500V shake meter, and its value should not be less than 6m.

380V electric or clever or motive use a 500V shake meter to measure the insulation resistance, and its value should not be lower.

The resistance value measured by the multimeter is all.

Dear, it's okay, it's normal.

Hello, I am glad to serve you and give you the following answers: large submersible pumps can have thermal resistance, which is mainly used to protect the operating state of the motor and submersible pump and prevent burnout and damage caused by excessive load. When the submersible pump fails, the thermal resistance will play a certain protective role, which can quickly disconnect the power supply of the submersible pump and prevent overload from burning out the motor.

Workaround:1Check whether the power supply voltage is normal, if the voltage is too low, it may cause the motor to be overloaded and malfunction, and measures should be taken to adjust the power supply voltage; 2.

Check whether the submersible pump has carbon deposits, and if so, it should be cleaned in time; 3.Check whether the thermal resistance is faulty, and if there is a fault, it should be replaced in time; 4.Check whether the motor of the submersible pump is faulty, and if there is a fault, the finger should be replaced in time.

Related knowledge: RTD is an electronic component, its function is to change the resistance value to the current value within a certain temperature range, so as to control the load of the motor and prevent overload from burning out the motor. It is divided into horizontal RTD and vertical RTD, and their main difference is that the resistance value of horizontal RTD changes with the change of temperature, while the resistance value of the vertical RTD does not change with the change of temperature.
