1. product description
(1) summery
KYN61-40.5 (Z) type key mounted open AC metal closed switchgear (hereinafter referred to as the "switchgear") it is applicable to the three-phase AC 50Hz power system, used for the power distribution rooms of power plants, substations and industrial and mining enterprises to accept and distribute electricity, and to control, protect and monitor the circuit.
This product meets the standard: GB3906<3-35kV AC Metal Closed Switchgear>, GB / T11022 <Standard Common Technical Requirements for HP Switchgear and Control Equipment>, IEC60298 <Rated voltage above 1kV and below 50kV AC is all closed switchgear and control equipment>.
(2)Conditions of use
1.Ambient air temperature: maximum temperature +40ºC. Minimum temperature -10ºC;
2. Altitude: <1000m;
3. Surrounding relative humidity: daily average <95%, monthly average < 90%:
4. Ambient air: not suitable for degree, serious pollution, flammable gas and violent vibration places;
5.If there is an earthquake, the earthquake intensity should not exceed 8.
(3)Structural characteristics
Switch cabinet structure GB3906-2006 and IEC298 pin installed metal closed switch equipment standard and design, the whole by the cabinet body and can be drawn out of the part (handcart) two grades. Cabinet structure is assembled type, bolted combination forming, with complete partition board will switch cabinet inside part of the circuit breaker room, main bus room, cable room and relay instrument room. The outer hulk protection grade is IP3X, and the protection grade of each compartment is IP2X. All structural components are reliably grounded. The compartment of the main loop system has an independent exhaust pressure release channel.
According to the use of handcart can be divided into circuit breaker handcart, voltage transformer handcart, measuring handcart, isolation handcart, etc., all kinds of handcart the same size, the same use of handcart has good interchangeability; The handcart has a test/isolation position and a working position in the cabinet, and each position is equipped with an interlocking device to ensure that the handcart cannot move freely when it is in the above two positions.
