A new product designed and developed based on the standard KYN28-12 armored mid mounted metal enclosed switchgear, used for direct starting of medium and high voltage motors. Its products have the following obvious advantages:
1.１ The outer shell of the product is completely made of aluminum zinc coated steel plate processed by CNC machine with multiple bending and forming, and assembled with bolts. It has high mechanical strength, effectively ensuring the neatness and beauty of the product. The cabinet door is coated with spray coating, which has strong impact resistance and corrosion resistance. The product casing has a protection level of IP4X.
1.2 The main switch of this product is equipped with a handcart vacuum circuit breaker;
1.３Regardless of the type of circuit breaker used, the air insulation distance of the bare conductor can be guaranteed to be greater than 125mm, and the composite insulation can be greater than 60mm. Their circuit breakers have unique advantages such as long lifespan, high reliability, minimal maintenance, and small size.
Technical parameters:
1. Suitable for 10kV, 6kV, 3300V, 4160V, 50Hz/60Hz high-voltage synchronous and asynchronous motors;
2. Applicable motor power: Electric motors that can be directly started under grid conditions
3. Continuous startup times: can meet the requirements for starting the electric motor
4. Wiring method: Front end of motor;
5. Protection method: microcomputer protection;
6. Protection level: IP4X；
7. Protection method: microcomputer protection.
