Functions and features of 3.6KV 1600A MV medium voltage electrica lswitchgear

The 3.6KV 1600A  MV medium voltage  electrical switchgear is based on the design of the armored metal-enclosed switchgear specified in GB3906-91. It consists of two main components: the cabinet and the central pull-out part, also known as the handcart. The cabinet is segmented into four compartments and has an IP4X protection level. Opening the doors of the smaller compartments and the circuit breaker room lowers the protection level to IP2X. This switchgear features various functional solutions for overhead incoming and outgoing lines, cable connections, and more. By arranging and combining these components, a complete power distribution system device is created. Its front-access design allows for easy installation, testing, and maintenance, enabling installation in various configurations such as back-to-back, double arrangement, or against a wall. These features enhance the safety, flexibility, and space efficiency of the switchgear.

Main technical parameters of 3.6KV 1600A MV medium voltage electrica lswitchgear

Main technical parameters of vacuum switchgear

When utilizing a circuit breaker to regulate a 3-10KV motor, the addition of a metal zinc oxide lightning arrester is necessary if the initial current demanded is below 600A. The particular requirements for this arrangement should be discussed and agreed upon between the user and our company. In the event the circuit breaker is employed to disconnect a capacitor bank, the capacitor's rated current must not surpass 80% of the circuit breaker's rated current.

Technical parameters of operating mechanism

The 3.6KV 1600A MV medium voltage electrica lswitchgear is made according to the armored steel confined switchgear in GB3906-91. The whole is made up of 2 mainparts: a closet and a main with drawable spare part (i.e. a handcart) (see Figure 1). The cabinet is separated right into 4 different areas, with an enclosure security level of IP4X. When the doors of each area and circuit breaker space are opened, the security level is IP2X. Outfitted with overhanging inbound and outbound lines, cable television incoming and outgoing lines, and other useful systems, set up and combined to create a complete set of power circulation system tools. This switchgear can be set up, debugged, and preserved from the front, so it can be back-to-back, set up in a double plan, and mounted against the wall surface, improving the security, flexibility, and reducing the footprint of the switchgear.

◆ Covering and others

The main structure of the switchgear is constructed from aluminum zinc slim steel plate, refined by CNC maker tool, and takes on several folding procedure, which not just has the advantages of high precision, solid rust resistance and oxidation resistance, but also makes the cabinet lighter in weight, greater in mechanical toughness, and a lot more visually pleasing in look compared to various other comparable equipment cupboards because of using numerous folding procedure. The cabinet takes on an assembled framework, linked by rivet nuts and high-strength bolts, which shortens the processing cycle, improves the universality of elements, occupies much less room, and is convenient for organizing production.

◆ Handcarf

The handcart frame is constructed from thin steel plates processed by CNC equipment devices. The handcart and cupboard are insulated and coordinated, and the interlocking mechanism is secure, reliable, and flexible. According to their usage, handcart can be divided right into circuit breaker handcart, voltage transformer handcart, metering handcart, isolation handcart, and various other types of handcart. According to module and block type variants, handcart of the same spec can be openly traded 100%. The handcart has an interference setting, a screening placement, and a functioning position inside the closet. Each setting is furnished with a placing device to make sure dependable interlocking. The procedure has to be performed according to the interlocking defense measures operation treatment. All handcart utilizes nuts and screws to relocate and exit, and its operation is light and versatile, suitable for on duty workers to operate. When the handcart requirements to be relocated far from the cabinet, a specialized transfer vehicle can be easily pulled out for various assessments and upkeep, And it embraces a mid installed design, with a little quantity for inspection, maintenance, and ease.

◆ Compartment

The primary electrical elements of the switchgear have independent compartments, particularly: breaker handcart room, busbar space, cable television space, relay instrument area. The defense level in between each area gets to lP2x; Except for the relay, all various other three formats have their own pressure relief networks. As a result of making use of a central format, the cord room space is substantially raised, permitting the tools to attach several cable televisions.

◆ Circuit breaker Compartment

Tracks are installed on both sides of the compartment for handcart 5 to move and glide from the separated setting and test placement to the working setting inside the closet. The partition 3 (shutoff) of the static get in touch with box 16 is set up behind the back wall of the handcart compartment. When the handcart relocates from the disconnected position test position to the working setting, the flaps on the upper and reduced fixed get in touch with boxes are related to the handcart and immediately open. When relocating the contrary direction, the flaps immediately close up until the handcart go back to a specific placement and completely covers the fixed contact box, developing effective seclusion. As a result of the different operation of the upper and lower valves, during upkeep, the valve on the real-time side can be locked to ensure that upkeep workers do not touch the real-time body. When the circuit breaker room door is closed, the handcart can also be run.

Via the observation home window of the center door, the placement of the handcart being gotten rid of and closed in the area can be observed, and the power storage space condition can be shown.

◆ Busbar Compartment

The primary busbar 18 is a single unit spliced and attached per other, repaired by the primary busbar 20 and the fixed call box. The primary busbar and connecting busbar are copper bars with rectangular cross-sections, utilized for high currents. When composite, dual busbars are made use of to construct them. The branch busbar is linked to the fixed get in touch with box 16 and the main busbar through screws and does not call for any other assistance. For unique requirements, the busbar can be covered with warm diminish tubes, insulation sleeves with connecting bolts, and end caps. Adjacent cabinet busbars are fixed with sleeve 19, to make sure that the air buffer preserved in between the attaching busbars can avoid melting in case of interior mistake arcs. Sleeve 19 can successfully restrict crashes to this cupboard and not spread to various other cabinets.

◆ The complying with layout shows the architectural components of the switchgear. All steel modular assembly structure, the closet body is made of imported light weight aluminum zinc layered plate with strong anti-corrosion ability, without surface treatment. It is processed by CNC high-precision tools and embraces innovative several folding procedure. The connection is gotten in touch with rivet nuts and high-strength screws, with high precision, light weight, and great stamina.

◆ The switchgear can be furnished with our company's VS1 collection, VD4 series, ZN65 collection and other vacuum cleaner circuit breakers, with large applicability and strong interchangeability. The handcart is outfitted with a working setting, a testing placement, and positioning and display screen devices at each placement, ensuring safety and security and reliability.

◆ The cable room can accommodate as much as 9 single core cables, and the equipment is equipped with trusted mechanical and electric interlocking devices, completely satisfying the "5 prevention" demands. Each area is outfitted with pressure relief channels to guarantee individual safety throughout operation.
