Structural features
The switch cabinet structure is designed according to the standard of armored metal enclosed switchgear in GB3906-2006 and lEC298. The whole is composed of cabinet body and withdrawable part(handcart). The cabinet structure is assembled, bolted and combined. The interi or of the switch cabinet is divided into circuit breaker room, main bus room, cable room and relay instrument room with metal partition. The enclosure protection grade shall reach IP3X, the protection grade between compartments shall be lP2X, and all metal structural parts shall be reliably grounded. There shall be an independent exhaust pressure release channel between compartments of the main circuit system.
Handcarts can be divided into circuit breaker handcarts, voltage transformer handcarts, star counting handcarts, isolation handcarts, etc. the overall dimensions of all kinds of handcarts are the same, and handcarts for the same purpose have good interchangeability; The handcart has test / isolation position and working position in the cabinet, and each position is equipped with interlocking device to ensure that the handcart cannot move freely when it is in the above two positions.
