Product Overview
KYN61-40.5(Z) refers to an armored, withdrawable, AC metal-enclosed switchgear (hereinafter referred to as the switchgear), which is a complete indoor power distribution device for three-phase AC systems with a frequency of 50 Hz and a rated voltage of 40.5 kV. It is used in power plants, substations, and industrial and mining enterprises for the reception and distribution of electrical energy, providing functions such as circuit control, protection, and monitoring, and is also suitable for applications involving frequent switching operations.
Scope of Application
The KYN61-40.5(Z) metal-clad, center-mounted switchgear is designed in accordance with the armored, metal-enclosed switchgear specified in GB 3906. It is suitable for three-phase AC power systems with a rated voltage of 40.5 kV and a rated frequency of 50 Hz, and is used for receiving and distributing electrical energy as well as for controlling, protecting, and monitoring circuits. In addition to widespread application in general power systems, it can also be employed in locations subject to frequent switching operations.
Applicable Environment
1. Maximum ambient air temperature: +40°C; minimum: -10°C; daily average temperature not exceeding 35°C.
2. Altitude does not exceed 1000 m
3. The daily average relative ambient humidity shall not exceed 95%, and the monthly average shall not exceed 90%.
4. Seismic intensity shall not exceed Grade 8.
5. The daily average water vapor pressure shall not exceed 2.2 kPa, and the monthly average shall not exceed 1.8 kPa.
6. Locations free from fire hazards, explosion risks, severe pollution, chemical corrosion, and violent vibrations
