The Keane frame of GCK is a combined assembly structure. All structural parts of the frame are galvanized and sprayed with plastic. The basic frame is connected with each other through screw fastening, and assembled into a complete control center cabinet. The cabinet structure has the following characteristics:
The frame is assembled with C-type materials, and the frame parts and special supporting parts are supplied by the company to ensure the accuracy and quality of the cabinet.
◇ the molding size, opening size and equipment interval of parts shall be modularized (modulus E = 20mm, the same below).
The internal structural parts are treated with plating edge.
◆ the top cover of the cabinet is removable, and the four corners of the cabinet top are equipped with lifting rings for lifting and shipping
◆ the cabinet frame is divided into three mutually isolated sections: bus room, functional unit room and cable room, which can prevent the spread of accidents
◆ functional unit (pumping part)
◆ the height modulus of the bending unit is 200mm, which is divided into five size series: 1 / 2 unit, 1 unit, 15 unit, 2 unit and 3 unit. Rated current of unit circuit 630A and below (see the figure above for appearance)
◆ each MCC cabinet can be installed with a maximum of 9 1-unit crowns or 18 1 / 2-unit crowns.
◆ the operating mechanism is mechanically interlocked with the draw out. When the main switch is in the close position, the draw out crown cannot be drawn out.
◆ the operating mechanism of stretching can be locked in the closing or opening position with a padlock, which can safely carry out the maintenance of electrical equipment.
◆ the back of the functional unit is provided with the inlet and outlet plug of the main circuit and the secondary plug of the auxiliary circuit.
◆ functional unit compartments are separated by metal partitions.
◆ the crown extraction unit adopts rotary propulsion mechanism, which has three position function and simple and reliable operation.
◆ GCK crown pulling propulsion mechanism adopts the movement mode of spiral track along the positioning part to realize the propulsion and extraction of functional units. In the process of propulsion and extraction of functional units, it realizes three position display and mechanical interlocking, and is equipped with microswitch. Electrical interlocking can be carried out in the test position.
When ordering, the user shall provide
◆ main circuit distribution system diagram and layout plan, rated working voltage, rated working current, setting current of protection device and necessary technical parameters.
◆ indicate the specifications of incoming and outgoing cables
◆ model, specification and quantity of main electrical components in the switch cabinet
◆ if bus bridge or bus duct is required between switch cabinets or incoming cabinets, specific requirements such as span and height from the ground shall be indicated
◆ when the switch cabinet is used under special environmental conditions, it shall be explained in detail when ordering.
◆ surface color of switch cabinet and other specific requirements.
