SMC inflating cabinet is a new generation of switch equipment, main switch can be permanent magnetic actuator of vacuum circuit breaker can also with spring mechanism of vacuum circuit breaker, the entire cabinet with air insulated and sulfur hexafluoride gas compartment combined, is compact and can be expanded for in distribution automation. Inflating cabinet has the characteristics of compact structure, flexible operation, reliable interlock etc., on various occasions, especially the harsh environment of the place), different user requirements can provide satisfactory solutions. The sensor technology and the latest protection relay, with the advanced technology and portable and flexible assembly plan, can meet the different needs of the user. Inflating cabinet used in power system small secondary substation, opening and closing, box type substation, residential, industrial and mining enterprises, large shopping malls, especially in airports, subways, railways and other occasions requiring higher power consumption.

use environmental conditions

a, ambient air temperature: the highest 40 DEG C (24-hour mean value does not exceed 35 degrees), a minimum of 25 DEG C;

b, altitude: not more than 3000m (more than 3000m and manufacturer coordination);

c, air humidity: Daily relative humidity average value not greater than 95%, monthly relative humidity average value not more than 90%;

d, in the secondary system in the magnitude of the induced electromagnetic interference does not exceed 1.6kv.

a, the cabinet body structure: inflatable compartment by 3 ~ 5mm thick stainless steel plate, the CNC machining after the welding robot and, welding deformation small, good air tightness, the rest of the compartment by high quality cold-rolled steel plate, CNC bending after welding, which has high precision, good strength characteristics; each functional unit are independent modules, assembly is convenient. All the sealing chamber is provided with a pressure relief channel, to maximize the protection of personal safety and equipment operation.

b, applicable standards: common specifications for GB/11022-1999 high-voltage switchgear and controlgear standards; GB/3906-1991 3 ~ 35kV AC metal closed switch equipment;

c, degree of protection, pneumatic isolation is IP67; low-voltage cabinet for IP4X.
