Functions and features of 12KV 2000A Armored Removable Ac Metal Enclosed Switchgear

The 12KV 2000A  Armored Removable Ac Metal Enclosed Switchgear is crafted in accordance with the armored metal-enclosed switchgear standards outlined in GB3906-91. It comprises two main components: the cabinet and the central pull-out portion, also known as the handcart. The cabinet is segmented into four distinct compartments. The enclosure protection level is IP4X, while the doors of each small compartment and the circuit breaker room offer IP2X protection when open. The switchgear features overhead incoming and outgoing lines, cable incoming and outgoing lines, and various functional solutions. Once arranged and combined, it forms a comprehensive power distribution system device. Its front-accessible design enables installation, debugging, and maintenance from the front, allowing for back-to-back, double, or wall-mounted installation, which enhances safety, flexibility, and space efficiency.

If the starting current of the 3-10KV motor controlled by the circuit breaker is below 600A, a metal zinc oxide lightning arrester needs to be included. The user and our company will discuss the specific conditions, such as ensuring that the rated current of the capacitor in the circuit breaker does not exceed 80% of its rated current when disconnecting the capacitor bank.

Technical parameters of operating mechanism

The 12KV 2000A Armored Removable Ac Metal Enclosed Switchgear is created according to the armored metal confined switchgear in GB3906-91. The whole is composed of 2 mainparts: a cabinet and a main with drawable extra part (i.e. a handcart) (see Figure 1). The cabinet is separated into four separate compartments, with a room defense level of IP4X. When the doors of each area and breaker area are opened, the defense level is IP2X. Furnished with overhanging incoming and outward bound lines, cable incoming and outgoing lines, and various other practical plans, arranged and integrated to create a total set of power circulation system devices. This switchgear can be mounted, debugged, and kept from the front, so it can be back-to-back, set up in a double plan, and set up versus the wall surface, boosting the security, flexibility, and decreasing the footprint of the switchgear.

◆ Shell and others

The main framework of the switchgear is made from aluminum zinc slim steel plate, refined by CNC device tool, and takes on multiple folding process, which not just has the advantages of high precision, solid deterioration resistance and oxidation resistance, however also makes the closet lighter in weight, higher in mechanical stamina, and much more aesthetically pleasing in appearance compared to various other comparable equipment cupboards because of making use of several folding process. The cabinet adopts a constructed structure, linked by rivet nuts and high-strength bolts, which reduces the processing cycle, improves the universality of components, occupies less room, and is convenient for organizing production.

◆ Handcarf

The handcart structure is assembled from slim steel plates processed by CNC device tools. The handcart and cabinet are insulated and collaborated, and the interlacing system is safe, dependable, and adaptable. According to their use, handcart can be separated right into circuit breaker handcart, voltage transformer handcart, metering handcart, seclusion handcart, and various other sorts of handcart. According to module and block kind variations, handcart of the exact same specification can be freely traded 100%. The handcart has a disconnection position, a screening setting, and a working position inside the cabinet. Each placement is equipped with a placing device to guarantee reliable. interlocking. The procedure has to be performed according to the interlacing defense measures operation treatment. All handcart utilizes nuts and screws to move and exit, and its operation is light and flexible, appropriate for working personnel to operate. When the handcart demands to be moved away from the closet, a devoted transfer automobile can be easily taken out for numerous examinations and upkeep, And it embraces a mid installed design, with a little quantity for inspection, maintenance, and convenience.

◆ Compartment

The main electric elements of the switchgear have independent areas, namely: breaker handcart area, busbar space, cord space, relay tool room. The security degree in between each compartment reaches lP2x; Besides the relay, all various other 3 formats have their own stress relief networks. Because of making use of a main layout, the cable television area space is considerably increased, permitting the tools to connect several cables.

◆ Breaker Compartment

Tracks are mounted on both sides of the compartment for handcart 5 to relocate and glide from the disconnected setting and examination placement to the functioning position inside the cabinet. The partition 3 (shutoff) of the fixed call box 16 is installed behind the back wall surface of the handcart compartment. When the handcart moves from the disconnected placement examination setting to the working placement, the flaps on the top and lower fixed call boxes are related to the handcart and automatically open. When relocating the opposite instructions, the flaps automatically close until the handcart go back to a specific position and totally covers the fixed contact box, creating effective seclusion. As a result of the separate operation of the top and lower shutoffs, during upkeep, the valve on the online side can be secured to ensure that maintenance employees do not touch the real-time body. When the breaker area door is shut, the handcart can additionally be operated.

With the observation window of the middle door, the setting of the handcart being taken care of and closed in the area can be observed, and the energy storage space standing can be shown.

◆ Busbar Compartment

The main busbar 18 is a single device interlaced and attached to every various other, fixed by the primary busbar 20 and the static call box. The primary busbar and linking busbar are copper bars with rectangular cross-sections, utilized for high currents. When composite, double busbars are made use of to construct them. The branch busbar is linked to the fixed contact box 16 and the major busbar via bolts and does not need any other support. For unique requirements, the busbar can be covered with warmth diminish tubes, insulation sleeves with connecting screws, and finish caps. Nearby cupboard busbars are taken care of with sleeve 19, so that the air buffer retained between the linking busbars can avoid melting in case of interior mistake arcs. Sleeve 19 can efficiently restrict crashes to this cupboard and not spread to various other closets.

Schematic diagram of switchgear structure

◆ The adhering to diagram reveals the structural elements of the switchgear. All steel modular assembly framework, the closet body is made of imported aluminum zinc layered plate with strong anti-corrosion capability, without surface area therapy. It is refined by CNC high-precision devices and takes on innovative multiple folding process. The connection is connected with rivet nuts and high-strength bolts, with high accuracy, lightweight, and excellent toughness.

◆ The switchgear can be outfitted with our firm's VS1 series, VD4 collection, ZN65 series and other vacuum breaker, with vast applicability and strong interchangeability. The handcart is geared up with a working setting, a screening position, and positioning and screen tools at each position, guaranteeing security and dependability.

◆ The cable space can accommodate as much as 9 solitary core cable televisions, and the devices is furnished with trusted mechanical and electrical interlocking tools, totally meeting the "5 prevention" demands. Each space is equipped with stress alleviation channels to make certain personal safety and security throughout operation.
