MODULAR DESIGN CONCEPT
The SMP Switchgear system is a modular concept based on the "building blocks" principle, which means that cubicles are produced in series. As a result, the modular SMP concept meets the highest technical standards in a rational, economically sound way. The combination of cubicles is unlimited. Very complex diagrams of distribution and transformer switchgear can be compiled through this extensive spectrum of possibilities. The semi-compact cubicles are particularly beneficial if the available space should pose a problem or if economical factors play an important role. Compartments also contain all functional interlocks which allows for effortless application, according to all current standards, and which allows installation in consumer work spaces. As a result, capacity loss will be minimal. Additionally, the compartments have been fitted with a system for pressure release which shields the user from the consequences of an internal arc.
Typical application:1. Power generation, transmission and distribution • Utilities (National generation / transmission / distribution company) • Private generation / transmission company • EPC company and etc. • Power supply companies • Energy producers • System operators.2. Industrial plants and general industrial sectors • Construction, EPC • Industrial plants, petrochemicals, etc. • Buildings, landmark, hospital, etc.
Standards and SpecificationsThe switchgear complies with the standards of IEC60298,GB3906,DL404 etc. Enclosure protection degree of switchgear is IP4X, protection degree is IP2X when the door of VCB room is open and the truck is be drew out.During the installation and running of electric system, observe all the relevant information in the IEC and the safety regulations in GB or local electrical utility, and consider the relevant information provided by Guilin Sanhua Mechanical&Electronical Automation Engineering Co.,Ltd.Normal Service ConditionsNormal service conditions of switchgear following:Ambient temperature in room:Maximum +40°CMaximum 24 hour average +35°CMinimum (according to "minus 15 indoor class") -15°CAmbient humidity in room: 95% and lessDaily average relative humidity less than 95%Monthly average relative humidity less than 90%Height above sea level at site less than 1000mEarthquake intensity: less than 8 degreeThis product should not be used under conditions of fire, explosion,earthquake and chemical corrosion environments.2.

3.1 Basic structure(Figure3/1)The basic structure of switchgear panel comprises the panel itself a removing part. The panel and main components can see in figure 3/1.Incoming-line panel or outgoing-line panel are diagram of basic switchgear panel,there are other derivative diagram,for example ,contact panel or metering panel .in addition,There are so many diagram of the switchgear panel with stationary type load switch,(SF6)VCB truck,VC truck,Disconnect truck. The panel has two maintenance modes. That is single-face maintenance and double-face maintenance. The detail of structure and main components, can reference order document.

3.2 Enclosure and clapboardThe enclosure and clapboard of the switchgears is made up from high quality steel, have very strong function to resistant oxidation and corrosion, and its rigidity and mechanical robustness is higher than common low-carbon steel board. Main materials for cubicles use ≥2.0mm zinc-aluminum-magnesium steel sheet or aluminum-zinc coating steel sheet, and adopt double-bender technology with features of high strength, good anti-corrosion and good anti-oxygenic property. No need for surface treatment. Parts assembling uses high strength bolts or rivet connection with features of high precision and good rigidity for fitting, Have been installed release of pressure plate on the top of three high-pressure chambers. When appear internal fault electric arc, air pressure heightens in high-pressure chamber, because that the doors of switchgear is already airtight coating, the pressure gas will clash out the release of pressure plat. Adjacent switchgears are isolated by its self side board, after putting the switchgears together, air buffer layer exist yet, it may prevent the switchgears from pronging and melted by electric arc. Low-voltage vault D is separate room with high-pressure area. Clapboard space isolate the VCB vault B with cable vault C, even if VCB. truck is moved(here the valve is closed self-motion),can prevent the operator from touching the electrification parts of bus bar vault A and cable vault C. releasing the tighten bolt, the level clapboard is removed, convenient for installation of cable seal terminal.3.3 Compartments in switchgear3.3.1 VCB Compartment (figure 3/1,3/3,3/5,3/6 showing)The vacuum circuit breaker trolly is installed in the breaker compartment with guide rails and can be moved between two different positions of operation, test,isolation. While the trolly move from service position to test/ isolation position, The movable door automatically covers the stationary contacts and opens in the opposite direction. The trolly can be operated when the compartment door is closed. Through the observation window on the door, you can see the position of the trolley, the ON (breaker closed)/OFF (breaker open) button on the trolley, Closed and open status indicators and charged/discharged status indicators.VCB TrollyThe trolly can be moved by manual. The structure of the trolly is made of the steel, the VCB and other equipment are installed on top of it. The arm of spring bush is installed on the pillar of the VCB,acts as an electrical connection when the trolley is inserted into the operating position. Signal, protection and control lines between the trolley and the switchgear, connected with a plug. The trolly is fixed on the test position as soon as it is pushed into the switchgear, and be connection to tgrounding of the switchgear. The location of the trolley can be seen through the observation window or the trolley electrical position indicator mounted on the panel of the low voltage compartment.In addition to vacuum circuit breakers, the handcart can be equipped with vacuum contactors, isolation devices and metering equipment.With Schneider HVX vacuum circuit breakerBus bar compartmentThe busbars are connected from one switchgear to another and are secured by branch busbars and bushings. The rectangular branch busbar is directly bolted to the main busbar without any coupling clamps. All bus bars and branch bus bars are covered with heat shrink tubing. The bushing plate and bushing isolate the busbar between the cabinets and have a supporting function. This support is generally required for switchgear with high electrical stress.Cable compartment(drawing 3/1)Current transformers and earthing switches are installed at the rear of the cable compartment. Lightning arresters can also be installed in the cable compartment. When the cable compartment door is opened, there is enough space for construction personnel to enter the cabinet to install cables (up to 6 cables can be connected in parallel). The bottom plate covering the cable entrance can be made of non-magnetic stainless steel plate. Sewn, removable, easy on-site operation. The opening of the reducing sealing ring that passes through the primary and secondary cables in the bottom plate should be adapted to the installed cables to prevent small animals from entering. For cable trenches with high humidity, it is recommended to seal the switchgear with fireproof mud and epoxy resin.Current transformerLow-voltage compartment (figure 3/1,3/2)The secondary components of the switch cabinet are installed in the low-voltage room and on the door. The control wire trough has ample space and has a cover plate. The left wire trough is used to arrange the wires going in and out of the cabinet, and the right wire trough is used to lay the internal connection of the switch cabinet. There are control wire crossing holes on the side plate of the low-voltage room to control the connection of the power supply.Our project at site, PT.
