KY28-12 type armored removable AC metal-enclosed switchgear
The KY28-12 type armored removable AC metal-enclosed switchgear (commonly referred to as KYN28-12 switch cabinet) is an important distribution device widely used in power plants, small and medium-sized generator power supply, industrial and mining enterprises distribution, and secondary substations in power systems. This equipment has become an indispensable part of modern power systems due to its excellent performance, high safety, and flexible operability.
1. Function
The KYN28-12 switch cabinet mainly has the following functions:
-
Power distribution and control: As a core component of the power system, this device can efficiently receive and distribute electrical energy while controlling and protecting the circuit. It precisely distributes electrical energy through internal components such as circuit breakers, current transformers, and voltage transformers, and performs flexible switching operations according to system requirements.
-
Protection function: The KYN28-12 switch cabinet has a complete protection mechanism that can quickly cut off the power supply in case of abnormal situations such as short circuits and overloads, protecting the equipment from damage and preventing accidents from escalating. At the same time, internal components such as fuses and surge protectors also play an important protective role.
-
Monitoring and measurement: The device is equipped with various instruments and sensors that can monitor parameters such as voltage and current in real-time, providing accurate data support for the operation of the power system. In addition, it can also achieve automatic fault detection and alarm through relay protection devices, improving the safety and reliability of the system.
-
Flexibility and expandability: The KYN28-12 switch cabinet can be configured and expanded according to actual needs, forming various distribution device schemes through different handcarts (such as circuit breaker handcarts, voltage transformer handcarts, etc.) and combinations to meet various complex power demands.
2. Installation method
The installation of the KYN28-12 switch cabinet is a complex and meticulous process that requires strict adherence to the steps outlined in the installation manual. The following are the general installation steps:
-
Unboxing inspection: After the equipment arrives on site, the first step is to check the integrity of the packaging to ensure that the equipment has not been damaged during transportation. At the same time, check whether the technical documents and accessories that come with the box are complete.
-
Foundation preparation: Choose a suitable location for installation based on the size and weight of the equipment. The installation foundation should be flat, stable, and meet design requirements. Mark the centerline and elevation line for equipment installation on the foundation for subsequent installation.
-
Equipment positioning: Use lifting equipment to hoist the switch cabinet into the designated position and perform initial fixing. During the hoisting process, care should be taken to keep the equipment stable to avoid collisions and scratches.
-
Adjustment and fixing: According to the design drawings and installation manual, make precise adjustments to the switch cabinet to ensure that its level and verticality meet the requirements. Then, use bolts to securely fix the equipment to the foundation.
-
Wiring and debugging: Perform wiring work according to the electrical schematic and equipment wiring diagram, ensuring that all connections are secure and reliable. After wiring is completed, conduct debugging and testing of the equipment, including main circuit resistance measurement, insulation resistance measurement, and circuit breaker operation tests, to ensure normal equipment performance.
-
Safety interlock inspection: Conduct a comprehensive inspection of the safety interlock devices of the equipment to ensure that they can operate correctly during operation, preventing accidents caused by misoperation. Special attention should be paid to checking the reliability of the interlock device between the handcart and the cabinet.
-
Acceptance and commissioning: After the equipment debugging is qualified, organize relevant departments for acceptance. After passing the acceptance, follow the operating procedures for commissioning and closely monitor the equipment's operating conditions to ensure stable and reliable operation.
Through the above steps, the KYN28-12 type armored removable AC metal-enclosed switchgear can be safely and stably installed in the power system and play its important role. During the installation process, strict adherence to safety operating procedures and the requirements of the installation manual is essential to ensure the quality of the installation and the safety of operation.
