Structural characteristics of

The structure of the switch cabinet is designed according to the standards of gb3906-2006 and IEC298 for armored metal closed switch equipment. The whole self-cabinet body and the uranium output part (handcart) are composed of two grades.

The cabinet body structure is modular, bolted and combined to form, and the inside part of the switch cabinet is divided into circuit breaker room, main bus room, cable room and relay instrument room by metal partition.

The external protection grade is up to IP3X, and the protection grade of each isolation chamber is IP2X, and all metal structures are reliably grounded. There is a pressure release channel for independent exhaust between the compartments of the main loop system.

Handcart according to use can be divided into the circuit breaker handcart, voltage transformer handcart, handcart metering handcart, isolation, etc., all kinds of handcart appearance is the same size, same purpose handcart with good compatibility;

The handcart has test/isolation room and working position in the cabinet. Interlock device is installed at each position to ensure that the handcart cannot move freely when it is in the above two positions.
