FAQ
Q: What types of high voltage switches can HCB-15 test?
A: HCB-15 series is suitable for almost all types of high voltage switching equipment, including vacuum circuit breakers, SF6 circuit breakers, oil-less/multi-oil circuit breakers, GIS combined electrical appliances, load break switches and disconnectors of 10kV to 500kV voltage class. It is compatible with spring, hydraulic and electromagnetic operating mechanisms, and can meet the test requirements of most mainstream brands and models of switchgear.
Q: What is the function of the built-in operation power supply?
A: The traditional circuit breaker test requires an external DC control power supply to drive the opening and closing coils, which is inconvenient for on-site test. HCB-15 has a built-in 30V~300V adjustable DC power supply with 20A peak output, which can directly drive the circuit breaker operating mechanism without external power supply, greatly simplifying the on-site test wiring and improving work efficiency. It also supports programmable output time to meet different test sequence requirements.
Q: What is the significance of measuring contact bounce?
A: Excessive contact bounce will cause the contacts to arc for a long time, aggravate contact ablation, and even cause contact welding in severe cases, which seriously affects the electrical life and breaking reliability of the circuit breaker. HCB-15 can accurately measure the bounce time and bounce times of each phase contact, and evaluate the contact assembly quality and mechanism buffering performance, which is an important basis for judging whether the circuit breaker can be put into operation safely.
Q: Can it perform auto-reclosing sequence test?
A: Yes. HCB-15 supports multiple operation sequence tests including "close-open", "open-close-open" and "close-open-close", and the time interval between each action can be set freely. It can simulate the actual auto-reclosing action process of the power system, test the mechanical action reliability of the circuit breaker under continuous operation, and evaluate the mechanism's energy storage and action coordination performance.
