Armored Movable Enclosed Switchgear KYN28A-12 type indoor AC metal-clad mid-mounted switchgear is suitable for three-phase AC systems with a rated voltage of 12kV and a rated frequency of 50Hz. It is used for receiving and distributing electrical energy and for controlling, protecting, and monitoring circuits. • The switchgear is designed according to GB3906-91 for armored metal-enclosed switchgear. It is mainly composed of a cabinet and mid-mounted drawable parts (i.e., trolleys). The cabinet is divided into four separate compartments, with an outer shell protection level of IP4X. The protection level between the compartments and when the circuit breaker chamber door is open is IP2X. • It provides overhead inlets and outlets, cable inlets and outlets, and other functional schemes. After being arranged and combined, it forms a complete power distribution system device. • Installation, debugging, and maintenance of this switchgear can be performed from the front. Therefore, it can be back-to-back, form double rows, and be installed against the wall, improving the safety and flexibility of the switchgear and reducing its footprint. • Ambient air temperature: Maximum temperature +40℃, minimum temperature -15℃ • Relative humidity: Daily average relative humidity: ≤95%; daily average water vapor pressure does not exceed 2.2KPa; monthly average relative humidity: <90%; monthly average water vapor pressure does not exceed 1.8KPa • Altitude: Below 1000m • Seismic intensity: Not exceeding 8 degrees • The surrounding air should not be significantly polluted by corrosive or flammable gases, water vapor, etc.
