Product Introduction

As society evolves, the demand for safe and reliable electricity usage grows. High-voltage circuit breakers play a dual role of control and protection in the power system, with their performance directly impacting the safe operation of the power system. Mechanical characteristic parameters are one of the key parameters for evaluating circuit breaker performance.

To meet the diverse needs of users for mechanical characteristic testing of various circuit breakers, Longdian Electric has meticulously developed a brand new circuit breaker mechanical characteristic tester. The GKC-HBS two-terminal grounded circuit breaker mechanical characteristic tester can accurately measure the mechanical dynamic characteristics parameters of various high-voltage circuit breakers with low oil, high oil, vacuum, SF6, and special types, featuring easy operation, precise data, strong anti-interference ability, compact size, and exquisite appearance. In addition to meeting the dynamic characteristic testing requirements of general high-voltage switches on the market, it also satisfies the testing of closing resistance and six-way two-terminal grounding, enabling the tester to effectively conduct mechanical characteristic testing on circuit breakers.
