The key of the switchgear is divided into fixed and rubber wheel type, and its structure is divided into open type, semi closed type and closed type. In terms of the application of natural environment, there are indoor and outdoor, electromagnetic induction work organization, torsion spring work organization and manual work organization.

The following editor will introduce how to choose the switchgear?

When selecting switchgear, indoor design or outdoor models and specifications must be selected according to the impact of application conditions. Mobile or vehicle type switchgear must be selected according to the number and stability of switchgear. The switch cabinet is cost-effective, but it is not as convenient as the car type. For distribution stations with low stability requirements and few power switch electronic counters, mobile switch cabinets can be selected as far as possible to control costs.

The key design scheme of the switchgear should be defined according to the provisions of high wiring rate. Please refer to the relevant mechanical guidelines for the key design drawings of the switchgear. The customer must select or design the secondary route of the scheme according to the needs of manipulation, accurate measurement, maintenance and data signals. After selecting the switchgear, check whether the key components in the cabinet have common faults according to the application status and short-circuit fault status.

When selecting the actual operation organization, it should be clear according to the working capacity of the power supply system of the wind farm. If there is DC power supply, try the electromagnetic induction high-voltage circuit breaker. The manual actual operation organization applied in small and medium-sized distribution stations is relatively simple, but the disconnection working capacity of the switchgear will be poor.
