Three-phase resin-insulated dry-type power regulator, voltage input terminal and output terminal are all 10KV class. On the primary winding of the dry voltage regulator, the on-load tap changer is connected by tapping, and the dry voltage regulator is continuously powered. In the case of the case, the voltage conversion is automatically performed. The main feature of the dry regulator is its automatic voltage conversion function, which also maintains voltage stability and ensures voltage quality.

★ With automatic voltage conversion function, it also has the characteristics of maintaining voltage stability and ensuring voltage quality.

★ Reliable uninterruptible power supply is more important to users, and the application of dry regulators is more extensive.

★ Integrated design of dry regulator, compact structure, small footprint and easy installation.

Conditions of Use

1. The altitude is not more than 1000m (special design is required when it is greater than 1000m).

2. Ambient temperature: the highest temperature +40 ° C, the hottest month average temperature +30 ° C, the highest annual average temperature +20 ° C;

Minimum temperature -25 ° C (for outdoor dry regulators)

Minimum temperature -5 ° C (for indoor dry regulator)

3. The waveform of the power supply voltage is approximately sinusoidal; the three-phase supply voltage is approximately symmetrical.

4. The protection grades are IP00, IP20, IP30, etc.; the cooling methods are air self-cooling (AN) and forced air cooling (AF). Both cooling methods need to ensure that the regulator has good ventilation conditions. The pressure device is installed in the basement or other poorly ventilated environment, and additional heat dissipation ventilation is required.

Product use and characteristics

SCBZG10 series three-phase resin insulated dry voltage regulator is suitable for three-phase 10kV voltage level power supply system, which is mainly used in 10kV power distribution station along rail transit engineering. It plays the role of automatically stabilizing voltage quality, isolating grid power and power load, eliminating high harmonics and not polluting the grid power. The specific features are:

1. The isolation transformer core is a three-phase three-column type, and the upper and lower iron yokes are respectively tightened by clips. The upper and lower clamps of the core are connected to the iron yoke through six pull plates, and the iron core supports the coil through the insulating spacer. fixed.

2. Strengthen the insulation between the coil layers and the outer layer; casting with filled epoxy resin not only improves the heat dissipation capability of the coil, but also eliminates the internal stress of the insulation layer; the plate-shaped integral clamp member has a compact structure and good ventilation effect. Improve the electrical performance and mechanical strength of the product and improve working conditions.

3. The core adopts high magnetic permeability and low loss cold-rolled grain oriented silicon steel sheet, 45° full oblique joint, step laminated structure, and high-strength polyester belt tying structure, which makes the core processing technology simple and quality. reliable. The core clamp is a flat clamp. Low noise, low no-load loss, and good heat dissipation.

4. The elastic nail structure is adopted between the coil and the iron core to ensure the integrity of the transformer under short-circuit shock and to ensure low noise during normal operation.

5. High and low voltage coils are wound by round, flat copper wire or copper foil according to the capacity. They are filled with epoxy resin insulation system with filler, glass fiber reinforced, thin insulation, cast under vacuum, and honeycomb cooling air passage. Low partial discharge, flame retardant, good heat dissipation, resistance to temperature changes, good crack resistance, high mechanical strength, short-circuit resistance, and good shock resistance.

6. The dry vacuum on-load tap-changer with high current technical level in China automatically adjusts the output voltage by adjusting the number of turns of the high-voltage coil, which is convenient for users. The on-load tap-changer of the dry regulator is fixed on a uniform base, and the connection between the switch and the transformer body is cabled.
