ENVIRONMENTALLY FRIENDLY CIRCUIT BREAKER SWITCH

New Products / New Technology

The FCHBV(S)-12/T630-20 is an environmentally friendly gas-insulated disconnector and circuit breaker switch. Compared to SF6 gas-insulated switchgear (GIS), it has the advantage of not containing the greenhouse gas $\textSF_6$, thereby achieving energy conservation and environmental protection. The product complies with the technical requirements of GB1984-89 and GB/T 1984-2014 for AC high-voltage circuit breakers. The main circuit ratings are 630A20kA (4s) and 25kA (3s); mechanical life is 10,000 operations, disconnector operations 3,000 times, and earthing switch operations 3,000 times.

CIRCUIT BREAKER ELECTRIC OPERATING MECHANISM

New Products / New Technology

This series of circuit‑breaker operating mechanisms is designed as auxiliary equipment for the closing and opening operations of high‑voltage ring‑main unit circuit breakers. The mechanism employs a tension spring that passes through the midpoint to control the closing action, while the opening action is governed by a compression spring. The product features a reclosing function and, when used in conjunction with an interlocking mechanism, provides interlocking and five‑protection functions. It boasts high reliability, with a mechanical life exceeding 10,000 operations. Each unit undergoes full inspection before leaving the factory and complies with the relevant requirements of GB 3804‑2004 "High‑Voltage AC Load Switches, 3.6 kV–40.5 kV," GB 3906‑2006 "AC Metal‑Enclosed Switchgear and Control Equipment, 3.6–40.5 kV," and GB 16926‑2009 "High‑Voltage AC Load Switch‑Breaker Combination Apparatus."
