LQHV-410 HV Switch Operating Power Supply – Reliable Testing for High-Voltage Circuit Breakers

The LQHV-410 HV Switch Operating Power Supply is a dedicated power source designed for inspecting and maintaining high-voltage circuit breakers and their operating mechanisms. It eliminates risks associated with traditional testing methods while offering portability, precision, and safety.

Technical Parameters

Why Choose the LQHV-410 for High-Voltage Testing?

Traditional methods for high-voltage switch testing (low-voltage tests) pose significant risks:

1. Using Field DC Systems (Control Cabinet)

• Risk of Short Circuits: May cause DC system failure or equipment damage.

• Safety Hazard: Direct grounding can collapse the entire DC system.

2. AC Power with Basic Rectification

• Heavy & Bulky: Voltage regulators are inconvenient for field use.

• High Ripple Output: Unstable DC affects test accuracy.

• No Isolation: Exposed casing risks electric shock.

Key Features of the LQHV-410 Power Supply

• Stable & Isolated Output: Fully isolated input/output for operator safety.

• Low Ripple Factor: Ensures precise DC output for accurate testing.

• Overcurrent & Overvoltage Protection: Safeguards equipment during operation.

• Lightweight & Portable: Easy to carry for field maintenance.

• Simple Operation: Minimal wiring, user-friendly design.

Applications in Power System Maintenance

The LQHV-410 is ideal for:

• High-Voltage Circuit Breaker Testing: Ensures reliable opening/closing operations.

• Preventive Electrical Tests: Verifies switchgear performance without risking DC systems.

• Field Maintenance: Compact design suits on-site inspections.

Technical Advantages Over Conventional Methods

By replacing outdated testing approaches, the LQHV-410 enhances safety and efficiency in high-voltage switch maintenance while complying with industry standards.
