Model meaning

Functions and Features

The switchgear is designed according to the armored metal closed switchgear in the GB3906-91.The whole is composed of two parts: cabinet and mid-type extractable parts (i. e. trolley) (see figure).The cabinet is divided into four separate compartments with shell protection rating of IP4X and IP2 X for compartments and circuit breaker doors.With overhead entry and exit line, cable entry and exit line and other functional scheme, to form a complete distribution system device after arrangement and combination.This switchgear can be installed, debugged and maintained from the front, so it can be installed back to back, forming a double arrangement and wall installation, improving the safety, flexibility and reducing the footprint of the switchgear.

• Case and other

The main cabinet of switchgear is to apply aluminum zinc steel plate, processed by CNC machine tool, and adopts multiple fold edge process, make the whole cabinet not only has the advantages of high precision and strong corrosion resistance and oxidation effect, and due to the multiple fold edge technology makes the cabinet than other similar equipment cabinet overall weight, high mechanical strength and beautiful appearance.The cabinet is made of assembly structure, connected with riveting nut and high strength bolt, which makes a short processing cycle, strong universal parts, less area and easy for organization and production.

• Handcart

The trolley skeleton is assembled with thin steel sheet processed by CNC machine tool.Handcar and cabinet insulation cooperation, the mechanism interlocking is safe, reliable and flexible.According to the use, the hand car can be divided into circuit breaker car, voltage transformer car, metering car, isolation car and so on.All kinds of manual cars according to the module, building block type change, the same specification of manual cars can be 100% free exchange.The trolley has a disconnection position, test position, and working position in the cabinet. Each position is equipped with a positioning device to ensure reliable interlocking, which must be operated according to the interlocking error prevention operation procedures. All kinds of trolley use nuts and wire bars to advance and exit, and its operation is light and flexible and suitable for operation by duty personnel.When the trolley needs to remove the cabinet, with a special transfer car, it can be convenient to take out, various inspection, maintenance; and use the mid-set type, the whole trolley volume is small, inspection, maintenance is very convenient.
