Switchgear KYN28A-12/24

Description
As is a reliable switchgear supplier, Minde provides various switchgears to you, satisfying your specific requirements. The KYN 28A-12/24 air-insulated metal-clad enclosed switchgear is a reliable power distribution equipment that operates at the rate voltage of 12kVor 24KV and a rated current of 3-phase AC 50Hz or 60Hz in the single busbar sectional power system. It is wildly applied in the power generator, substation, factories and tall buildings to receive and distribute electrical power. Meanwhile, this air insulated enclosed switchgear is used to control and monitor the circuit. Of a highly reliable quality, it meets such authoritative standards as the GB3906 standard and the DL/T404 standard.

12kV/24kV Metal Clad Switchgear

Design features of the Switchgear KYN28A-12/24
1. To get more about its structure, please resort to the following figure;
2. Entirely metal-clad, this electrical switchgear enjoys a brilliant assembly structure and a wide range of assembly methods;
3. The cabinet is made of aluminized and galvanized sheets which, imported from foreign markets, are processed by the CNC machine tool with some advanced flanging techniques. Connected with the quality nuts and bolts, this cabinet enjoys a highly precise workmanship, sound anticorrosion property, lighter weight, and high intensity. Additionally, its components are interchangeable with those of other switches.
4. The switchgear could be easily refitted to the domestic ZN63A circuit breaker or the imported vacuum circuit breakers. The converted switch could still enjoy rich applications, high reliability, free maintenance and long mechanical endurance;
5. Operation and testing positions will be established for the handcart of this air-insulated switch, both of which are equipped with safe and reliable positioning devices and display devices.

Product Features
1. Completely metal-clad and enclosed, this air-insulated metal-clad enclosed switchgear could effectively prevent accidental spreading. Besides, its low voltage section and the high voltage section are separate from each other;
2. When its door is closed, this electrical switch gear's protection class could be up to IP4X. This essential door could ensure the operators' safety by preventing objects outside from approaching to the live parts and withdrawable parts of the switchgear;
3. The cable compartment, of enough space, makes it easier to install and maintain the equipment;
4. The interlock it is equipped with, simple and reliable, could effectively prevent mis-operations;
5. Equipped with an advanced relay-protecting device, this metal-clad enclosed switchgear can control the power system automatically;
6. It enjoys an attractive appearance and highly precise workmanship;
7. If this air-insulated is installed against wall, you can maintain it from the front part. Besides, the double-side maintenance which is convenient and reliable is also available for you;
8. The pressure relief passages in the trolley compartment, busbar compartment and cable compartment of this switchgear could ensure the safety of operators and the equipment by preventing accidental spreading caused by certain electrical faults.

Ambient Conditions
1. Ambient air temperature: -15℃ to 40 ℃;
2. Relative humidity: under 95%(daily average), 90%(month average);
Vapor pressure: under 2.2Kpa (daily average), 1.8Kpa(month average);
3. Altitude: under 3000m;
4. Earthquake intensity: Lower than magnitude 8;
5. No corrosive or combustible gas, vapor, etc.;
6. No frequent excessive vibrations;
7. Contact our engineering staff before you apply this metal-clod enclosed electrical controller in a working place where conditions are not consistent with the prescribed ones in GB3906.

Structure of the Switchgear
This KYN28 air-insulated metal-clad enclosed switchgear consists of two major parts, namely the cabinet and the handcart. The cabinet is divided by metal sheets into several separate compartments, such as the busbar chamber, circuit breaker room, cable room and relay instrument room.
As for the handcart, there are following types of handcarts available for you: vacuum circuit breaker handcart, vacuum contactor handcart, voltage transformer handcart, arrester handcart, isolating handcart, transformer and fuse handcart.

1. busbar chamber;
2. circuit breaker room;
3. cable room;
4. relay instrument room.
