Caractéristiques structurelles
Switchgear structure GB3906-2006 and IEC298 armored metal closed switchgear standard design, the whole by the cabinet and withdrawable part (handcar) of two levels. The structure of the cabinet is assembled, and the part of the switchgear body is separated into the circuit breaker room, the main bus room, the cable room and the relay instrument room with a metal partition. The protection level of the enclosure reaches IP3X, the protection level of the compartments is IP2X, and all metal structural parts are reliably grounded, and the compartments of the main circuit system have independent exhaust pressure relief channels.
According to the use of the handcart can be divided into circuit breaker handcart, voltage transformer handcart, measuring handcart, isolation handcart,etc., all kinds of handcart outline size is the same, the same purpose of the handcart has good interchangeability; The cart has a test/isolation position and a working position in the cabinet, and each position is equipped with an interlock device to ensure that the cart cannot move freely when it is in the above two positions.
