Wind power integrated circuit breaker

Abstract

The invention discloses a wind power integrated circuit breaker, which relates to the technical field of circuit breakers, and comprises a frame, a solid-sealed polar pole, an isolation knife, a grounding knife, a wire inlet copper plate and a wire outlet copper plate, the solid-sealed polar pole is arranged at the upper part of the frame, the top of the isolation knife is arranged at one end of the solid-sealed polar pole, and the bottom of the isolation knife is connected with the wire inlet copper plate; the wire inlet copper plate is arranged on one side of the frame, and the wire outlet copper plate is arranged on the other side of the frame. The top of the grounding knife is arranged at the lower part of the frame; and the grounding knife is connected with the wire outlet copper plate. The wind power integrated circuit breaker is novel in appearance, compact in structure, safe, reliable, easy and convenient to operate and convenient to install and maintain, has an obvious isolation fracture, meets the five-prevention interlocking function, has enough dynamic stability and thermal stability, is safer, and better protects equipment, personnel and property, the problems of installation and maintenance can be better solved for customers, and the problems of disordered layout, many lap joint surfaces, high potential safety hazard, high cost and the like of electric appliance components in the high-voltage chamber are completely solved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a wind power integrated circuit breaker. Background technique [0002] In the protection configuration of the high-voltage side of transformers in terminal substations, box-type substations and ring network power supplies, new energy dedicated wind power integrated circuit breakers-combined electrical appliances are widely used to break rated currents, overload currents and short-circuit currents. The wind power integrated circuit breaker-combined electrical appliance has the function of protecting the transformer from overload and preventing the equipment from running without phase. It is especially suitable for the control and protection of the ring network power supply unit and the terminal transformer. It is the best choice for the transmission network equipment of the wind power generating set. [0003] Now some technical conditions have low safety factor, large pro...
