Functional design:
The size of the rationalization and internal layout.
Reduce cover an area of an area.
Simple main circuit and auxiliary circuit connection.
Easy to install, upgrade costs under control.
In line with international standards:IEC60439-1.IEC60529 and IEC 60947.
Feature:
The basic framework of the basic framework, BLOKEST medallion ark by standard prefabricated components assembled. These artifacts have a variety of specifications, can be assembled into the framework of different sizes. Switch cabinet is composed of four different areas, respectively is:
1 main room, 2 components, 3 wire cable room, 4 auxiliary chamber.
Three kinds of depth of 3 kinds of width: BLokset series framework by combining the basic framework and the expansion of the switch cabinet, can constitute a variety of depth and width of the switchgear. There are three basic framework can be depth: 400 mm and 600 mm / 1000 mm; By a 400 mm and a basic framework of the 600 mm deep. There are three basic framework can be width: 700 mm, 900 mm (Mw), 1200 mm (used for MasterpactMT40b MT50 or MT63). According to the need, can be in 700 mm on both sides of the basic frame of increasing expansion tank (200 mm or 200 mm). Shell according to the required level of protection can be divided into IP20, IP31, IP42, IP54, framework can install different cover plate.
Switchgear arrangement
Blokset modular design can make the arrangement and electrical switchgear of the configuration of the match.
Switch cabinet can be side by side or back-to-back placed behind: according to the indoor space can be determined, back-to-back installation can make cut by half the total length of switchgear.
From the front or back into the switch cabinet wiring area: if the terminal is located in the switch cabinet in the lateral compartment, can from the front, so I can let the switch cabinet against the wall.
If the terminal is located in the back of the switch cabinet, entering from behind.
Into the line or wire cable can enter: from the top or bottom of the switchgear if switch cabinet is installed on the secondary floor or in cable trench, cable from the bottom into the best.
You can enter the thread slot by the switchgear at the top of the power supply
Internal equipment
Functional units in IEC60439-1 standard definition for all electrical equipment and machinery parts of the same function form part of a low voltage switch device and control device. The height of the functional unit dominated by its 50 mm module to determine the number of a switch cabinet can contain 40 module, each module high 50 mm.
Circuit breaker, contactor, thermal relay, inverter and soft starter is installed on the vertical mounting plate. Vertical installation of circuit breaker can have three types: fixed, plug-in, drawer.
Composition of switchgear switch element is installed in the switch cabinet of a drawer, can ensure reliable delivery of maintenance and repair. A switch cabinet can be equipped with 12 drawer, each with three 50 mm high modulus, level of the main line to occupy four modules. Larger components can be installed in a deeper 6, 9, 12 or 15 high modulus, in the drawer of the motor installed in the drawer cannot exceed 250 kv feeder circuit devices.
