10KV line automatic voltage regulatorsurvey:

10KV line automatic voltage regulatorSVR-10 series line regulatorThe entire coil is divided into three parts: series excitation coil, parallel excitation coil, and control coil. Among them, the series excitation coil is a winding with multiple taps, which are connected in series between the input and output through different contacts of the on load tap changer. By changing the tap position, the transformation ratio of the autotransformer can be changed to achieve the purpose of adjusting the voltage; The three-phase parallel excitation coil is the common winding of the autotransformer, generating a magnetic field for transmitting energy; The control coil provides working power and sampling signals for the controller.

A three-phase on load tap changer is a switch that can switch contacts under load. In an automatic voltage regulator, the taps of the series winding are connected to different contacts of the tap changer, and the output voltage can be changed by adjusting the transformer ratio through the switching contacts. Considering the lifespan of the tap changer and the precision requirements of user voltage regulation, the commonly used on load tap changers have two gears, 7 and 9.

10KV distribution line regulator: a device that tracks changes in line voltage and automatically adjusts the device's body ratio to ensure stable output voltage. It can automatically adjust the input voltage within a range of 30%, especially suitable for lines with large voltage fluctuations or drops. Connect this type of voltage regulator in series at the middle and rear ends of 6kV, 10kV, and 35kV lines to adjust the line voltage within a certain range, ensuring a stable supply voltage for users and reducing line losses; In addition, the SVR feeder automatic voltage regulator is also suitable for substations where the main transformer does not have voltage regulation capability. This type of voltage regulator is connected in series on the outgoing side of the substation transformer to ensure that the voltage on the outgoing side is qualified.

Analysis of SVR High Voltage Feedline Automatic Voltage Regulator:

In rural power grids, especially in some remote areas, there are a certain number of long-distance lines with power supply radii exceeding the prescribed limits. Considering the cost of the lines, it is not possible to solve the problem by deploying a large number of high-voltage distribution points, which leads to difficulty in ensuring the terminal voltage, failure to meet power factor requirements, and high line losses. Therefore, voltage regulators need to be used to increase the voltage.

Similarly, fields with high requirements for power quality such as oil fields, hospitals, coal, metallurgy, and chemical industries also require the use of voltage regulators.

Product function:

Power system: Low voltage can affect the output of power generation and supply equipment, reduce power supply reliability, and also affect the economic benefits of power enterprises themselves. When the voltage drop is particularly severe, accidents such as voltage collapse, frequency drop, and large-scale power outages may even occur.

When the voltage is 10% lower than the rated voltage, the flux of the incandescent lamp decreases by 30%. When the voltage is 10% higher than the rated voltage, the lifespan of the bulb is reduced by half.

Low voltage can also affect a series of issues such as air conditioning operation, mobile phone charging, and TV signal reception capability.

System loss: When the transmission power is constant, the system loss is inversely proportional to the square of the operating voltage. If the voltage decreases, the current and loss increase accordingly.

The benefits of SVR high-voltage feeder automatic voltage regulator:

a. Comparison of voltage improvement schemes for power lines

In order to improve the voltage level of the power line and ensure the quality of power supply, effective measures must be taken to regulate the voltage of lines with severe voltage drops. At present, there are several ways to regulate line voltage:

1. Constructing small substations (disadvantages: large investment, long cycle)

2. Replace the wiring (Disadvantages: high investment, long cycle)

3. Change transformer tap (disadvantage: small adjustment range)

4. Install compensating capacitors (disadvantage: small adjustment range)

5. Installation of voltage regulator for distribution lines (advantages: low cost, quick effect)

The first two options have high investment and long cycle, and are not very economical choices for lines with dispersed loads. Changing the splitter can generally only be adjusted by ± 5% and requires the installation of a load switch. Install compensation capacitors, and the compensation amplitude is generally only 3%. So installing a line regulator is an economical, convenient, maintenance free, and fully automatic solution.

b. Comparison with on load transformer

1. From a cost perspective, a line regulator is an autotransformer that has a lower cost compared to an on load regulator transformer.

2. Users using on load transformers can only change the voltage of a single user, while line regulators can adjust the voltage of the entire user group, greatly reducing costs.

3. Voltage regulation can also be achieved using ordinary on load transformers, but on load voltage regulation transformers have high impedance, generally reaching 4% -6% or more, and have a large voltage drop on the line. The impedance of the distribution line voltage regulator developed by our company is less than 1%, which has a very small voltage drop on the line.

4. In terms of service life, our independently developed tap changer also has a lifespan of one million cycles.

The intelligent trend of SVR high-voltage feeder automatic voltage regulator:

In response to the requirements of intelligent power grid, our technical team has carried out multiple technical upgrades to the controller of the distribution line regulator to adapt to the needs of the power grid in the new situation.

1. The controller has wireless communication function and can observe the operation or setting parameters of the regulator in a timely manner through monitoring; GPRS/CDMA remote communication can also be optional, allowing users to monitor the operation of the voltage regulator in real-time without leaving their homes;

2. Display and record output terminal voltage, current, daily action times, total action times, current gear, with gear and * * * gear indication

3. The controller adopts high-speed digital processing chips, with high signal detection accuracy, fast processing speed, strong anti-interference ability, special lightning protection measures, and can adapt to harsh outdoor environments;

4. This product has bidirectional power flow recognition function and can be applied to feeder lines with small hydropower generation, stabilizing the line voltage during wet and dry seasons.
