35kV vacuum circuit breaker in the following system of high voltage circuit breaker applications are power plants, substations and distribution equipment important electrical equipment, which bears the control and protection of the task. Normal and turned off by it to the load circuit, by its failure to cut fault circuit to limit the scope of the accident, to ensure safe operation. Therefore Yiyang vacuum circuit breakers, high voltage circuit breakers select appropriate or not directly related to the power system security, supply Changsha vacuum circuit breaker that is related to our national economic production ...... welcome to inquire to buy! Common electrical and mechanical aspects of the breaker failure were: electrical faults aspects: protection malfunction or improper setting value, or current, voltage transformer circuit failure; adverse secondary circuit breaker vacuum insulation Ganzhou, DC phylogenetic points ground, the DC positive and negative power supply is turned on, which is equivalent to relay action, a signal caused by tripping. Mechanical faults: tripping tripping mechanism untenable; positioning screw to adjust properly, so crank arm three high; trailers spring deformation, lack of elasticity; wheel damage; trailers slope, errors or wheel to drag the shelves contact little face. Nanchang vacuum circuit breakers, Huayi Electric Power (certified), vacuum circuit breaker provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
