Depression draws out style switch cabinet
Product Model: S-GCK
Product Name: Depression draws out style switch cabinet

Scope:
S-GCK family of low-voltage withdrawable switchgear (hereinafter referred to as "switching equipment") applies to rated voltage 380V, AC three-phase four-wire, three-phase five-wire system, electric power systems as power plants, substations, industrial and mining enterprises and high-rise buildings by electricity, feed, reactive power compensation, power metering, lighting and centralized control of motor used. Hop products meet GB7251 "Low-voltage switchgear and control equipment", JB/T9661 "low-voltage withdrawable switchgear", IEC60439.1 "Low-voltage switchgear and control equipment" standard.

Conditions of Use:
■ Altitude: not exceed 2000m
■ Humidity: -5 ℃ - +40 ℃, the daily average temperature is not higher than +35 ℃
■ Relative Humidity: +40 ℃ in temperature of less than 50%, at lower temperatures to allow a standard high relative humidity. For example, when 90% of +20 ℃.
■ there is no fire, explosion, heavy pollution, chemical corrosion and severe vibration place.
■ vertical tilt with no more than 5 ℃.
■ applies to the following temperature transport and storage, -25 ℃ - +55 ℃, in a short time (less than 24h) does not exceed +70 ℃.
■ If the use conditions are not met, should be the customer ordering the company to the proposed consultation.

Structural features:
S-GCK, S-GCL and assembled the basic framework for the structure, the framework of all the structures have been galvanized, spray, each connected through the screw fastening the basic framework, and then need to add doors, baffles, partitions , drawer, mounting bracket and the bus and the electrical components such as parts, assembled into a complete control center cabinet, the cabinet structure has the following features.


Frame
Framework assembled by C profiles of local, frame parts and special auxiliary parts by matching supply company, to ensure the accuracy and quality of the cabinet.
■ Parts of the forming size, hole size, equipment, implementation of modular intervals, (modulus E = 20mm, the same below)
■ internal structure of the parts are galvanized.
■ cabinet removable roof to be folded, removed top cover is easy to install standard bus, Roof of the four corners with rings, used for lifting and loading
■ External by phosphate treatment, and electrostatic epoxy powder coating.
■ frame into bus room, functional unit room, cable rooms isolated from each other interval of three to prevent proliferation and to facilitate live maintenance of the accident. Functional unit (drawer part)
■ functional unit, feed unit, motor unit, the common power supply unit.
■ drawer unit high modulus is 200, divided into 1 / 2 units, 1 unit, 1.5 unit, 2 unit, 3 unit cell size series of five circuit rated current 630A the following.
■ Each MCC cabinets can be installed up to a unit of the drawer 9 and 18 1 / 2 unit of the drawer.
■ compartment's door by the main switch of the operating mechanism and drawer mechanical linkage, the main switch in the closing position, the drawer can not be drawn.
■ the operation of the main switch body can be a locked padlock, or sub-gate closing position, can be safely carried out electrical equipment maintenance.
■ functional unit with the main circuit back into the outlet plug, plugs and grounding the second auxiliary circuit plug.
■ grounding plug connected to the drawer in the separation test location, to ensure the continuity of the circuit
■ functional unit compartment separated by metal partitions.
■ compartment of the valve, with the push and pull drawers open and close automatically, so that the compartment does not touch the vertical bus.
■ drawer unit is rotating forward body with three-position function, the operation simple and reliable.

■ Bus System
■ small range of vertical bus with polycarbonate plastic shell closed.
■ S-GCK, S-GCL bus system uses three-phase four-wire, three-phase five-wire system, the level of bus installed on the Roof, N line, PF line both the small Roof equipment, but also to install f nr cabinet bottom.
■ Three-phase horizontal bus copper bus bar, high mechanical strength, good heat dissipation. The level of copper busbar switchgear selection
