The switch cabinet is mainly divided into fixed type and vehicle type, and its structure is divided into open type, semi closed type and closed type. In the aspect of application natural environment, there are indoor and outdoor, electromagnetic induction working mechanism, torsion spring working mechanism and manual working mechanism. So, how should we choose the necessary switchgear? Now let's talk about the selection of switch cabinet.
When selecting the switch cabinet, the indoor and outdoor models and specifications must be selected according to the natural environment of the application, and the fixed or automobile switch cabinet must be selected according to the total amount and safety regulations of the switch cabinet. The switch cabinet is cost-effective, but not as convenient as the car. For distribution stations with low stability regulations and few power switch counts, fixed fixed switch cabinets can be used as far as possible to control costs.
The specific design scheme of the switch cabinet shall be defined according to the provisions of high wiring rate. Refer to the relevant electrical equipment guide for the key design drawings of the switchgear. The customer must select or design the secondary route according to the regulations of manipulation, accurate measurement, maintenance and information. After selecting the switch cabinet, check whether the key components in the cabinet have common faults.
When selecting the actual operating mechanism, it shall be determined according to the distribution capacity of the distribution station. If there is DC power supply, try electromagnetic induction high-voltage circuit breaker. The actual manual operation mechanism of small and medium-sized distribution stations is relatively simple, but the disconnecting capacity of the switchgear is poor.
