Overview

HXGN□-24 ring main unit switchgear (hereinafter referred to as “switchgear”), for rated voltage In ring network power supply or radiation power supply systems with a rated current of 24kV and below 630A, it is especial-ly suitable for loading pre-installed substations The station is used as the control and protection of the power system. This product is equipped with an insulated shell of FLN36-24D type sulfur hexafluoride load opening Off or FLRN36-24D type load switch-fuse combination electrical appliance, with small size, light weight, easy operation, operation force Light, interlocking, reliable, and mainte-nance-free, it is a medium-voltage switchgear required for urban power grid transfor-mation and construction.

This product has a “combined one point and one grounding” three-station arc interrupter, equipped with a “five-proof” function (to prevent load separation
and main Switch; prevent accidental entry into the live interval; prevent acciden-tal opening and closing of the main switch; prevent live hanging of the ground wire: prevent the ground switch from being in the connected position Power transmission), reliable interlocking, high fracture insulation strength, large crawl distance design, pressure equalizing cover protection for the outlet end, special dynamic kiss seal And fixed seal design, coupled with advanced technical perfor-mance and lightweight and flexible assembly solutions, can fully meet the ev-er-changing market The requirements for modernization are a new generation of medium-voltage switchgear for equipping urban power grids.

This product conforms to: GB3906 “3~ 35kV AC metal enclosed switchgear”G-B/T11022 “High voltage switchgear and Common technical requirements for con-trol equipment standards “, IEC298” AC metal-enclosed switching devices with rated voltage of 1kV and below 50kV “Equipment and control equipment “, DL/T404” Indoor AC high voltage switchgear ordering technical conditions “standard.
