Product category: Product Center switchgear Series Product Description: reasonable structure, safe and reliable, small volume, light weight, corrosion resistance and oxidation resistance, easy maintenance, intelligent control, safe and reliable performance features: kyn28-12kv switchgear is a distribution equipment with advanced technology, stable performance, reasonable structure, convenient use, safe and reliable. Safe and reliable The low-voltage chamber and high-voltage chamber are separated independently The bus is insulated with heat shrinkable material, which has high insulation performance Quick closing earthing switch is used for earthing and has the ability to close short circuit current The operation of all equipment, including the opening and closing of the circuit breaker, the pushing or moving out of the circuit breaker handcart, and the opening and closing of the grounding switch, can also be carried out when the door panel is closed With reliable locking device, it can effectively prevent misoperation Through the front and rear observation windows of the door panel, it is convenient to check the opening and closing status of the circuit breaker, the position of the handcart, the energy storage status of the mechanism, the opening and closing position of the grounding switch and the connection of the cable head The protection grade of the shell is IP4X, which can prevent dirt and small animals from entering The handcart is maintenance free, and its supporting operating mechanism only needs a little maintenance The handcart has good interchangeability and it is very convenient to replace the circuit breaker The secondary line is laid in the large-scale trunking, which is beautiful and easy to check, and has wide applicability It can be used in the way of cable and bus overhead Multiple parallel cables can be connected in parallel Service condition: normal service condition Ambient temperature: the maximum temperature is + 40 ℃, the minimum temperature is - 40 ℃, and the average value measured within 24 hours is not more than 35 ℃ The humidity conditions are as follows: —— The average value of daily relative humidity should not exceed 95%; The average value of monthly relative humidity is not more than 90%; —— The average value of daily steam pressure shall not exceed 2.2kpa; The average monthly water vapor pressure exceeds 1.8kpa; Condensation occasionally occurs under such conditions; If the altitude does not exceed 2000m, it must be explained in advance if it needs to exceed 2000m under special circumstances; The surrounding air is not obviously polluted by dust, smoke, corrosive and / or combustible gas, steam or salt spray; The vibration or ground motion from the outside of switchgear and control equipment can be ignored; The amplitude of electromagnetic interference induced in the secondary system shall not exceed 1.6kv under special service conditions When it is used under the normal environmental conditions beyond GB / t11022, the company and the user can negotiate and reach an agreement on the special operating conditions beyond the normal operating conditions. In order to prevent condensation, the switchgear is equipped with heater, which should be put into use when the switchgear is in standby state. The heater should also be put into operation during normal operation of switchgear. Scope of application: Kyn28-12kv indoor AC metal armored removable switchgear (hereinafter referred to as switchgear) is suitable for indoor three-phase 50 / 60Hz power system with rated voltage of 12kV. It is mainly used in power plants, substations, industrial and mining enterprises and high-rise buildings to receive and distribute electric energy and control, protect and monitor the circuit.
