Functions and features of 3.6KV 2500A New Type Of Armored Removable Ac Metal Enclosed Switchgear

The 3.6KV 2500A  New Type Of Armored Removable Ac Metal Enclosed Switchgear is based on the design of armored metal-enclosed switchgear outlined in GB3906-91. It consists of two main components: the cabinet and the central pull-out part known as the handcart. The cabinet is divided into four separate compartments, offering IP4X protection. Opening the doors of the smaller compartments and the circuit breaker room results in IP2X protection. It accommodates overhead incoming and outgoing lines, cable connections, and various functional features, allowing for the creation of a complete power distribution system device through arrangement and combination. This switchgear supports front installation, debugging, and maintenance, enabling installation in various configurations such as back-to-back, in a double setup, or against a wall. These installation options enhance safety and flexibility while minimizing floor space requirements.

Main technical parameters of 3.6KV 2500A New Type Of Armored Removable Ac Metal Enclosed Switchgear

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 starting current falls below 600A. The specific requirements for this arrangement are determined through discussion between the user and our company, taking into account the capacitor bank's rated current, which should not surpass 80% of the circuit breaker's rated current.

Technical parameters of operating mechanism

The 3.6KV 2500A New Type Of Armored Removable Ac Metal Enclosed Switchgear is created according to the armored steel enclosed switchgear in GB3906-91. The entire is composed of two mainparts: a closet and a main with drawable extra component (i.e. a handcart) (see Number 1). The cabinet is divided right into 4 different areas, with an enclosure protection degree of IP4X. When the doors of each compartment and circuit breaker space are opened, the protection level is IP2X. Outfitted with overhead inbound and outgoing lines, cable television incoming and outward bound lines, and various other practical plans, set up and incorporated to develop a full collection of power circulation system devices. This switchgear can be installed, debugged, and kept from the front, so it can be back-to-back, arranged in a double setup, and set up versus the wall, improving the safety, adaptability, and decreasing the footprint of the switchgear.

◆ Covering and others

The primary framework of the switchgear is constructed from light weight aluminum zinc thin steel plate, processed by CNC device device, and embraces several folding process, which not just has the advantages of high accuracy, strong rust resistance and oxidation resistance, yet additionally makes the closet lighter in weight, higher in mechanical stamina, and extra visually pleasing in look contrasted to other similar tools closets due to the use of several folding process. The closet takes on an assembled framework, linked by rivet nuts and high-strength screws, which shortens the processing cycle, improves the universality of components, inhabits less room, and is convenient for organizing manufacturing.

◆ Handcarf

The handcart framework is put together from slim steel plates processed by CNC equipment tools. The handcart and closet are shielded and worked with, and the interlocking mechanism is safe, reliable, and adaptable. According to their usage, handcart can be split into circuit breaker handcart, voltage transformer handcart, metering handcart, isolation handcart, and various other kinds of handcart. According to module and block type variations, handcart of the exact same spec can be easily traded 100%. The handcart has an interference position, a screening setting, and a functioning setting inside the closet. Each position is furnished with a positioning device to ensure trustworthy interlocking. The procedure has to be performed according to the interlocking security measures operation treatment. All handcart uses nuts and screws to relocate and exit, and its procedure is light and versatile, suitable for working employees to run. When the handcart requirements to be moved away from the cabinet, a specialized transfer automobile can be quickly pulled out for numerous evaluations and maintenance, And it adopts a mid installed style, with a small quantity for assessment, maintenance, and convenience.

◆ Compartment

The major electrical components of the switchgear have independent areas, specifically: breaker handcart room, busbar area, cable room, relay tool room. The defense level between each compartment reaches lP2x; With the exception of the relay, all other 3 layouts have their own stress alleviation channels. Due to making use of a central layout, the cable television room area is significantly raised, permitting the equipment to connect numerous cables.

◆ Breaker Compartment

Tracks are mounted on both sides of the compartment for handcart 5 to relocate and glide from the disconnected position and test placement to the working position inside the closet. The partition 3 (valve) of the fixed get in touch with box 16 is mounted behind the back wall of the handcart compartment. When the handcart moves from the separated placement examination position to the working setting, the flaps on the top and lower static get in touch with boxes are linked with the handcart and automatically open. When moving in the contrary direction, the flaps immediately close up until the handcart go back to a certain setting and totally covers the fixed call box, developing reliable isolation. Because of the different procedure of the top and reduced valves, throughout maintenance, the shutoff on the real-time side can be locked to make certain that upkeep employees do not touch the online body. When the breaker area door is shut, the handcart can also be operated.

Via the monitoring home window of the middle door, the placement of the handcart being thrown away and enclosed the area can be observed, and the power storage standing can be displayed.

◆ Busbar Compartment

The major busbar 18 is a solitary device entwined and linked per other, repaired by the primary busbar 20 and the static get in touch with box. The primary busbar and connecting busbar are copper bars with rectangular cross-sections, utilized for high currents. When composite, double busbars are made use of to assemble them. The branch busbar is connected to the static call box 16 and the major busbar via screws and does not call for any other support. For special requirements, the busbar can be covered with heat shrink tubes, insulation sleeves with connecting bolts, and finish caps. Adjacent cabinet busbars are repaired with sleeve 19, to make sure that the air buffer retained in between the attaching busbars can stop melting in the event of interior mistake arcs. Sleeve 19 can efficiently limit mishaps to this cabinet and not spread to various other closets.

◆ The complying with layout shows the architectural elements of the switchgear. All steel modular assembly structure, the cupboard body is constructed from imported aluminum zinc layered plate with strong anti-corrosion capacity, without surface area therapy. It is processed by CNC high-precision tools and embraces sophisticated several folding procedure. The link is connected with rivet nuts and high-strength bolts, with high precision, light weight, and great strength.

◆ The switchgear can be furnished with our business's VS1 collection, VD4 collection, ZN65 collection and various other vacuum cleaner breaker, with broad applicability and strong interchangeability. The handcart is furnished with a working setting, a screening placement, and placing and screen gadgets at each setting, ensuring safety and security and reliability.

◆ The cable television room can suit up to 9 solitary core cords, and the devices is geared up with reputable mechanical and electric interlocking devices, totally fulfilling the "five avoidance" needs. Each area is outfitted with pressure alleviation networks to make sure individual safety during operation.
