Electric Control Panel KYN28-12 Series High/medium/low Voltage Switchgear

Electric control panel KYN28-12 series high/medium/low voltage switchgear

 

 

 

1. Switch cabinet (also known as complete switch or complete distribution device): It is an electrical equipment mainly composed of circuit breakers; It refers to that the manufacturer assembles relevant high and low voltage electrical appliances (including control appliances, protection appliances, measuring appliances), buses, current carrying conductors, insulators, etc. in closed or open metal cabinets according to the requirements of the electrical primary main wiring diagram, as devices for receiving and distributing electric energy in the power system.

2. High voltage switchgear: A general term for high-voltage switches mainly used for power generation, transmission, distribution, and energy conversion, as well as control, measurement, protection devices, electrical connections (busbars), enclosures, support components, etc.

3. The "five preventions" in the protection requirements of switchgear: preventing accidental opening and closing of circuit breakers, preventing live opening and closing of isolation switches, preventing live closing of grounding switches, preventing grounding of circuit breakers, and preventing accidental entry into live compartments.

4. Corresponding relationship between the position and phase sequence of the busbar:

5. Protection level: The degree of protection provided by the shell, partition, and other parts to prevent the human body from approaching live parts and touching moving parts, as well as to prevent external objects from invading internal equipment.

 

Definition of protection level abbreviation

IP1X prevents objects with a diameter greater than 50mm from following

1. Prevent solids with a diameter greater than 50mm from entering the shell;

2. Prevent a large area of the human body (such as hands) from accidentally touching live parts or moving parts inside the shell

IP2X prevents objects with a diameter greater than 12.5mm

1. Prevent solids with a diameter greater than 12.5mm from entering the shell;

2. Prevent hands from touching live parts or moving parts inside the shell

IP3X prevents objects with a diameter greater than 2.5mm

1. Prevent solids with a diameter greater than 2.5mm from entering the shell;

2. Prevent tools or metal wires with a thickness (diameter) greater than 2.5mm from touching live or moving parts inside the cabinet

IP4X prevents objects with a diameter greater than 1mm

1. Prevent solids with a diameter greater than 1mm from entering the shell;

2. Prevent tools or metal wires with a thickness (diameter) greater than 1mm from touching live or moving parts inside the cabinet

IP5X dustproof

1. It can prevent dust from entering to the extent that it affects the product;

2. Completely prevent contact with live parts or moving parts inside the cabinet

IP6X dust density

1. Completely prevent dust from entering the shell;

2. Completely prevent contact with live parts or moving parts inside the cabinet
