Structural components of busbar trunking equipment:
Insulation support - is a component of busbar trunking equipment used to support conductors in busbar trunking equipment.
Installation board - a board used to support various components and suitable for installation in complete sets of equipment.
Installation frame - a frame used to support various components and suitable for installation in a complete set of equipment.
Shell - A shell is a component that protects equipment from certain external factors and prevents direct access to the equipment in all directions. Its protection level is at least IP30.
Door - a hinged or sliding cover.
Cover plate refers to the upper and lower shell surfaces of the outer shell, usually a component on the bus duct equipment used to cover the opening on the outer shell. Fix it with screws or similar methods, and generally do not disassemble the equipment after it is put into operation.
Side panels are the left and right shell surfaces of the casing, usually referring to a component on busbar trunking equipment that is used to cover the openings on the casing. Fix it with screws or similar methods, and generally do not disassemble the equipment after it is put into operation.
Insulated partition - a component used to protect against direct contact from all directions at the entrance and arcs from switching devices and similar devices.
Live parts - Conductors or conductive components used to conduct electricity in normal use, including neutral conductors but excluding neutral protective conductors.
Bare conductive component - a touchable conductive component of electrical equipment that is typically not charged, but may become charged in the event of a malfunction.
Protective conductor - a conductor that is electrically connected to the following components to prevent the risk of electric shock.
——Exposed conductive components;
——External conductive components;
——Main grounding terminal;
——Grounding electrode;
——The grounding point or artificial neutral contact of the power supply.
Neutral conductor - a conductor that is connected to the neutral point of a system and capable of transmitting electrical energy.
Neutral protective conductor - a grounding conductor that serves as both a neutral conductor and a protective conductor.
Grounding fault current - the fault current flowing into the grounding point.
A type of protection against direct contact with current - preventing dangerous contact between the human body and exposed conductive parts.
Electrical clearance refers to the straight-line distance between two conductive components with different potentials.
Creepage distance - The shortest distance between two conductive components with different potentials along the surface of the insulating material.
Impulse withstand voltage - the highest peak value of an impulse voltage with a certain waveform and polarity, which will not cause breakdown under specified test conditions.
Power frequency withstand voltage - the root mean square value of the power frequency sine voltage that will not cause breakdown under specified test conditions.
Pollution refers to the condition of all external substances, such as solid, liquid, or gas, that can affect dielectric strength or surface resistivity.
Pollution level - a classification of environmental conditions based on the frequency of occurrences of conductive or hygroscopic dust, free gases or salts, and surface dielectric strength or resistivity decreases due to hygroscopicity or condensation.
The temperature rise is higher than the temperature value of electrical equipment at room temperature.
Spring support - overcomes the adverse effects caused by the self weight of the bus duct and releases tension.
Dust board - a connecting accessory that prevents dust from entering the bus duct equipment.
Joint cover plate - a type of connecting accessory used to connect the upper and lower parts of bus duct sections for the purpose of achieving dust tightness in electrical equipment.
Joint side panel - a connecting accessory used to connect the left and right sides of bus duct sections to achieve dust tightness of electrical equipment.
Copper braided tape - an installation accessory that solves the overall grounding of the shell.
Plug in box - an electrical distribution equipment that easily leads out branch lines, usually equipped with air switches for opening and closing.
