Type AC low-voltage distribution cabinet
One purpose
Type AC low-voltage distribution cabinet is suitable for power plant substations The AC rated working voltage rating of factories and mines
The power distribution system with working current up to 100% is used as the power conversion, distribution and control of power lighting and distribution equipment
The AC low-voltage distribution cabinet is based on the Ministry of Energy’s General Electric Power The requirements of users and the design department are based on the principles of safety, economy and reasonableness
The new low-voltage distribution cabinet products designed on the principle of reliability have high breaking capacity, high dynamic and thermal stability, and electrical solutions are flexible and convenient to combine
Series and strong practical structure The novel features of high protection level can be used as a replacement product for low-voltage complete sets of switchgear
The AC low-voltage distribution cabinet complies with the standards for low-voltage complete sets of switchgear and control equipment, low-voltage complete sets of switchgear and control equipment
Two product models And meaning
~_
Three conditions of use
The ambient air temperature shall not be higher than + and not lower than the average temperature within the room shall not be higher than +
The altitude of the indoor installation and use location It shall not exceed
The relative humidity of the surrounding air shall not exceed when the highest temperature is +. A larger relative humidity is allowed at lower temperatures
For example, when +, it should be considered that accidental occurrences may occur due to temperature changes. Effects of condensation
Pollution level
When installing the equipment, the inclination with the vertical plane should not exceed br/> When users have special requirements, they can negotiate with the manufacturer
Four electrical properties
~_
Main circuit plan
The main circuit of the cabinet is designed with different plans and different specifications. Including functional changes of auxiliary circuits and changes in control voltage
Derived plans and specifications
Among them, medium-sized plans and specifications
Type plans and specifications
Type plans and specifications
/> The main circuit scheme was selected after soliciting the opinions of the majority of design and application departments. The scheme required by the power plant was increased and the rated current was increased
to suit the selection of distribution transformers up to and below
In addition, in order to adapt to reactive power compensation The capacitor compensation cabinet is designed according to the needs of the main circuit scheme and has a total of specifications
Auxiliary circuit scheme
The design of the auxiliary circuit is divided into two parts: the power supply scheme and the power plant scheme. There is enough space in the cabinet to install both Secondary components
Main busbar
The overlapping surfaces of the copper busbars are treated with tin enameling process
Selection of electrical components
The cabinet mainly uses more advanced electrical appliances that can be mass-produced in China Components such as
and
type rotary operating knife switches are special components designed to meet the needs of the unique structure of the cabinet. It changes
the mechanical operation method and retains the advantages of the old product. A utility model of electrical components
If the design department selects new electrical components with better performance and more advanced technology according to user needs, the cabinet has good installation flexibility and generally will not be caused by updating the electrical components. Difficulties in manufacturing and installation
In order to further improve the dynamic stability of the main circuit, a cabinet-specific combined busbar clamp and insulating support piece are used
The busbar clamp is made of high-strength and flame-retardant alloy thermoplastic The molded insulation has high strength and good self-extinguishing performance. The structure is unique and only needs to be adjusted
The building blocks can be easily combined into single or double busbar clamps. The insulation support is a sleeve-type molded structure with low cost and high strength
It solves the defect of insufficient creepage distance of old products
Five structural features
The cabinet body of the AC low-voltage distribution cabinet adopts the form of a general cabinet and is constructed by partially welding and assembling cold-formed steel
Frame parts and special supporting parts are supplied by the designated steel production factory to ensure the accuracy and quality of the cabinet
The parts of the general cabinet are designed according to the modular principle and have molded mounting holes with a high universal coefficient, which allows the factory to achieve pre-production It not only shortens the production and manufacturing cycle but also improves work efficiency
When designing the cabinet, the heat dissipation problem during the operation of the cabinet is fully considered. There are different numbers of heat dissipation slots at the upper and lower ends of the cabinet
When the electrical components in the cabinet heat up, the heat rises and is discharged through the upper slot, while the cold air is continuously replenished from the lower slot into the cabinet to make the sealed cabinet form a natural ventilation channel from bottom to top to achieve the purpose of heat dissipation
The cabinet adopts the method of golden ratio to design the shape of the cabinet and the division of each part in accordance with the requirements of modern industrial product design.
The division size makes the overall appearance beautiful and new.
The cabinet door is connected to the frame with a rotating shaft-type movable hinge. It is easy to install and disassemble. A mountain-shaped rubber plastic strip is embedded in the folded edge of the door to close the door. When the door is opened, the strip between the door and the frame has a certain compression stroke, which can prevent direct collision between the door and the cabinet and improve the protection of the door. Level
The instrument door equipped with electrical components is connected to the frame with multiple strands of soft copper wire. The installation parts in the cabinet are connected to the frame with knurled screws to connect the whole cabinet
The cabinet forms a complete grounding protection circuit
The topcoat of the cabinet has strong adhesion and good texture. The whole cabinet is in matte color to avoid the dazzling effect and create a more comfortable visual environment for the personnel on duty. The top cover of the cabinet can be removed when needed to facilitate the on-site operation. Assembling and adjusting the main busbar. The four corners of the cabinet top are equipped with lifting rings for lifting
and shipping
The protection level of the cabinet can be selected by the user according to the requirements of the use environment
