China GDFQ-100 Electric Protection Sphere Gap Manufacture and Factory

GDFQ-100 Electric Protection Sphere Gap

Brief Description:

Discharge sphere gap consists of a pair of spherical electrodes of equal diameter. When integrated into a complete test system—comprising a high-voltage test transformer, control console, voltage regulator, and water resistor—it serves to measure high voltage and protect the test object during power-frequency high-voltage testing.

Features

• Intelligent Calibration: Features automatic calibration of the sphere gap distance, eliminating errors caused by mechanical loosening of the voltage-equalizing spheres during transport (requires 15mm and 30mm standard gauges).

• Multiple Adjustment Modes: Offers both manual and intelligent sphere gap adjustment to meet the diverse setup requirements of different customers.

• Flexible Operation: Supports both remote control and touch-button operation modes for greater ease and speed of use.

• Comprehensive Display: Includes a visual distance scale showing sphere movement, an intuitive smartphone-style battery level indicator, dynamic lift/lower status indicators, and more.

• High Safety: Allows sphere gap adjustment via remote control from outside the high-voltage test area, eliminating operational risks associated with manual adjustment.

• Intelligent Voltage Presetting: Calculates and displays the discharge protection voltage under reference conditions based on the sphere gap distance in real-time.

• Over-travel Protection: Provides limit protection and an audible alarm if the device exceeds mechanical movement limits, preventing instrument damage due to operator error.

• High Insulation Performance: Utilizes umbrella-shaped, high-strength nylon insulating rods to increase surface creepage distance and enhance longitudinal insulation.

• High Reliability: Insulating supports are evenly distributed horizontally at 120-degree intervals, enhancing structural stability and ensuring the voltage-equalizing spheres remain perfectly centered and level.

• High-Precision Data Acquisition: Uses dual high-precision A/D chips to simultaneously acquire distance and battery level data.

• License-Free Frequency Band: Operates on the 433MHz wireless frequency with a transmission range of 500m (under clear line-of-sight conditions).

• Strong Interference Immunity: The system is immune to system crashes or malfunctions caused by electromagnetic or impulse interference resulting from air-gap discharge and breakdown.•
