Meter capacity increase from 220 volts to 380 volts Do you want any information?

If you are Guangdong Power Grid Company.

The information required for the meter capacity increase business is as follows:

1. For the customer's identity information, the identity information of the person in charge and the power of attorney must be provided if the customer is not handled by himself.

2. Proof of ownership of the property at the electricity address (if the capacity is increased within the scope of the original electricity consumption, if the electricity area and the nature of the electricity remain unchanged, and the original address building has no addition, reconstruction or reconstruction, it is not necessary to provide the property ownership certificate of the electricity address, and the specific situation shall be subject to the on-site investigation by the staff.) ）。

The required information shall be provided in the original, as well as 1 copy verified by the customer to be consistent with the original and signed, enterprises and institutions.

The client signs and affixes the official seal in the photocopy. When handling business, resident customers need to sign and confirm on the "electricity business bill", and enterprise and institution customers must affix the official seal on the "electricity business bill".

There are differences in the information in different cities, and the specific information should be subject to the information of the staff.

95598 "Public Platform My Electricity Business Handling Business Change Capacity Increase Click "Handle" and follow the prompts to fill in the basic information and submit.

You can pay attention to the "China Southern Power Grid 95598" public platform, click on the "" number in my personal center, and you can query the user number by binding the mobile phone number reserved by the power supply company or the ID number of the head of the electricity meter.

After completing the application for installation, the power supply department will arrange staff to make an appointment with you for on-site service, complete the on-site investigation and collect the information, and then you can install the meter and send electricity.

We hope you find ours helpful.

That's impossible. 380 voltage rewiring is required for installation.

Hello, dear. You can follow the process below: 1If the customer does not handle the personal information and the power of attorney, the personal certificate information and power of attorney must be provided; 2.

Proof of ownership of the property at the electricity address (if the capacity is increased within the original electricity consumption range, if the electricity consumption area and the nature of the electricity consumption remain unchanged, and there is no addition, reconstruction or reconstruction of the original address building, it is not necessary to provide the ownership certificate of the electricity address sock roll property 3The required information shall be provided in the original, as well as 1 copy verified by the customer to be consistent with the original and signed, and the enterprise and institution shall sign and affix the official seal of the customer in the copy.

Summary. After entering the subpayment, you can apply for activation according to the prompts on the page, and whether it can be activated is subject to the system review result.

Hello! Cronies are buried in the slippery ants, I'm glad for your question, what information is needed to increase the capacity of the 380 meter? Help you to inquire: customer identification information, if you do not handle it yourself, you must also provide the identity certificate information and power of attorney of the person handling the preparation;

The identity information of the customer must also provide the identity information of the person in charge and the power of attorney if the customer is not handled in person;

If the power consumption area and the nature of the electricity consumption remain unchanged, and the original address building has no addition, reconstruction or reconstruction, it is not necessary to provide the property ownership certificate information of the electricity address, and the specific situation needs to be returned to the staff for on-site investigation. ）

The required information shall be provided in the original, as well as 1 copy of the copy of the virtual fiber that has been verified by the customer to be consistent with the original and signed, and the customer of the enterprise and institution shall sign and affix the official seal in the photocopy. When handling business destruction and fuel services, resident customers need to sign on the "electricity business sheet" to confirm, and enterprise and institution customers must affix the official seal to the "electricity business bill".

After entering the subpayment, you can apply for activation according to the prompts on the page, and whether it can be activated is subject to the system review result.

The 30KW working current of single-phase electric heating (heating wire) equipment is I=P U=30000W, 220V=136A

The 30KW working current of the three-phase electric heating equipment is i=p (

Assuming that the power factor cos-p is last:

The 30KW working current of single-phase power (motor) equipment is: I=P (U*Cos-P)=30000 (220*, if the instantaneous current at start-up is considered, it is beneficial to select the current standard 200A.

The 30kw working current of the three-phase power equipment is: i=p (

When choosing an ammeter, consider that the instantaneous current that is 5 to 7 times the working current should be 350A direct ammeter (it is estimated that there is none, it is recommended to use a current transformer to read).

The direct ammeter is selected for electric heating equipment, and its range should be at least 10A higher than that of the electrical equipment when it is working normally.

Power equipment should consider the instantaneous current at the time of starting, especially the high-power, the start-up often requires low speed, high current, high torque, and the current passed through in the preliminary stage is about 5 7 times of normal operation), and the range selection of the direct ammeter should also be 5 7 times of the current during normal operation.
