Overview
KYN28A-12/24KV High Voltage Withdrawable Switchgear (hereinafter referred to as “switchgear”) is suitable for three-phase AC 50Hz power system, used for accepting and distributing electric energy and controlling, protecting and monitoring the circuit.
It is a newly introduced and developed high-current, high-break switchgear, which can also be used as a high-voltage generator outlet.
This product conforms to the standards: GB3906 “3-35kV AC metal-enclosed switchgear”, GB/T11022 “Common Technical Requirements for High-voltage Parallel Switchgear and Controlgear Standards”, IEC298 “AC Metal-enclosed Switchgear and Controlgear with Rated Voltage of 1 kV or more than 52kV and below”.
Product Features
- Metal armor closure effectively prevents the spread of accidents;
- Complete isolation of high and low voltage rooms;
- Adopting a double-sided maintenance design, compact structure and convenient maintenance;
- The circuit breaker adopts a modular design, with a simple and reliable structure and long service life;
- Complete five protection interlock functions to prevent misoperation and achieve door closing operation;
- Fully resistant to internal fault arc design, up to 40kA/1S;
- Various main switches can be selected, such as VCB, vacuum contactors, and load switch handcarts;
- It can be equipped with an electric operation module to achieve remote driving of circuit breakers and grounding switches;
- Intelligent components can be configured to achieve real-time monitoring functions such as circuit breaker mechanical characteristics, one click sequential control, visual operation, temperature, partial discharge, etc. At the same time, it can obtain comprehensive data from automatic collection, storage, and analysis equipment for power monitoring, energy consumption management, and health status assessment, comprehensively improving the full lifecycle management capability of switchgear.
Working Conditions
- Ambient temperature：-30℃ ~ +50℃；
- Altitude: Not exceed 2500m above sea level；
- Ambient humidity: Daily average RH ≤ 95%;
- Monthly average: RH ≤ 90%
- Water vapor pressure: Daily average RH ≤ 2.2kPa;
