HV8 indoor AC high-voltage vacuum circuit breaker

Product Overview


HV8 is an outdoor high-voltage switchgear with rated voltage of 12KV and three-phase AC 50Hz. It is a product developed and manufactured by introducing the technology of ABB in Switzerland in combination with the development status and production capacity of the domestic industry. The overall structure of the product is in the form of integrated installation of switch body and operating mechanism. It adopts a composite insulation structure, which has no pollution, no explosion hazard and high insulation level. The operating mechanism of this series of products is spring energy storage type, which can be operated by AC or manual. The main electrical circuit adopts the solid-sealed pole, which is small in size, without explosion hazard, high in insulation level, and higher in maintenance-free level, and can effectively protect the vacuum arc extinguishing chamber from impact and collision; The mechanism adopts advanced surface treatment process and lubrication technology, which improves the anti-rust ability of the product, ensures the reliability of the product during the expected service life, and is suitable for hot and humid areas; The main circuit has strong adaptability to the environment, and the primary part is three-phase floor-type structure. The upper and lower outlet bases and arc extinguishing chambers are solidly sealed with epoxy resin APG process, so that there is no dust accumulation on the surface of the arc extinguishing chamber, and to prevent the vacuum arc extinguishing chamber from being damaged by external factors, so as to ensure that it can be used in humid, hot and polluted environments.
