Overview of special booster regulators for tunnels and mines

TNSJA series single-phase oil-immersed inductive non-contact automatic booster voltage stabilizer is used for tunnels, mine roadways and other power lines that are too far away, resulting in too low voltage at the end of the power supply, causing various mining machines to fail to work normally. Even burn all kinds of electrical equipment. Weihao's power stabilizer cabinet can automatically stabilize the voltage in the range of input voltage (304-456V) at 400V output. Make all kinds of machines at the end work normally. This voltage stabilizer has the characteristics of strong overload capacity, moisture-proof and waterproof, non-contact, maintenance-free, overload protection, short-circuit protection, automatic adjustment and other functions. Tunnel construction booster, oil-immersed induction booster voltage stabilizer.

Suitable places for booster regulators for tunnels and mines:

1. Highways, mine tunnels: Conveyors, shotcrete machines, air compressors and other mechanical equipment to stabilize voltage;

2. Factory: large-scale machine tools, color printing machines, coating machines, SMT/CNC/spark machines and other high-precision equipment to stabilize voltage.

Features of booster voltage regulator for tunnel mine

1. Wide voltage regulation range: ultra-wide voltage regulation range, fast response speed and high precision;

2. No contact, never wear: The main interior is the induction voltage regulator IVR, there is no carbon brush, no mechanical chain, no spark and other contact wear parts, and the service life is more than 15 years;

3. Stepless voltage adjustment (brushless): Linear stability, stable output voltage without step change;

4. LED digital display: input, output voltage, load current and other electrical parameters are clear at a glance;

5. Strong preset function: output voltage, output accuracy and protection limit can be set arbitrarily;

6. Stepless voltage adjustment (carbon-free): linear stability, stable output voltage without step change;

7. Over-capacity and strong load capacity: This model can be loaded with 100% and can be used continuously.

Solutions for excessive voltage drop in long-distance transmission

  1. Use a 380v booster to increase the voltage compensation by 60-100v to a certain value (safety value). When the motor starts, the voltage of the contactor coil will not be the low-voltage trip value, so it can be started. After starting, the voltage Will drop to around 400v, and 380v after load.

  2. Adopt one 380v to 1200v booster and one 1200v to 400v transformer produced by our company. The 1200v voltage is transmitted through 95 square millimeters to 2000 meters, and then the step-down treatment is performed to change the 1200v to 400v, which reduces the current on the line and reduces the line loss. Make the end equipment operate normally. This requires the wire to be insulated.

  3. (Suitable for high equipment) Use one of our company's boosters to stabilize the voltage, increase the voltage to a value, the equipment starts to drop the voltage, we compensate the voltage drop, and compensate the voltage before the contactor trips. The device starts normally and the voltage returns to normal.
