Power Distribution Cabinet Cgs Low Voltage Switchgear Assembly Waterproof Enclosured Power Distribution Box Power Supply Outside Switchgear Enclosure

Purpose
    GCS low voltage withdrawable switch cabinet is a modular distribution device. There are two types of structure. One is the outgoing switch installed in the drawer which can be drawn out and connected to the bus by plug-ins; the other is the insert plastic shell switch installed in the fixed interval where the front door can be opened. The withdrawable switch cabinet of two kinds of structures can be repaired under the condition of other electrified interval, and the same module can be exchanged. Operators and charged bodies strictly separated, high safety. Suitable for power plant, substation, petrochemical industry, factory and mining enterprises and high-rise building departments, as three-phase AC frequency of 50 (60) Hz rated working voltage to 380V power system power, power distribution and motor control center, capacitance compensation and other power conversion, distribution and control. Can also meet the needs of automatic user and computer interface.

Characteristic

• The cabinet body is made of 2.0mm galvanized steel plate, which is composed of modular steel frame and assembled without welding. The door and sealing plate are made of environmental protection plastic spraying technology without chemical treatment.
• The energy unit room, bus room and cable room are separated by steel plate, and the functional compartments are strictly separated.
• The horizontal bus is placed in the bus room on the top of the cabinet.
• Drawer and switch position and state are clearly marked, and each position can be locked.
• Single cabinet out of the circuit many, up to 22.
• Products comply with iec439-1, G7251, zbk36001-89 standards.

Installation and use
    After the device arrives at the receiving location, it should first check whether the packaging is intact. If problems are found, the relevant departments of the contract should be notified in time to make business records, analyze the reasons together, and make visas and aftercare.Products that are not installed immediately should be placed in an appropriate place in accordance with normal use conditions or electrical equipment storage regulations, and kept in a safe place.
    Generally, it is assembled by a single unit or 2-5 power distribution cabinets. The width of the parallel assembly unit is less than or equal to 3000mm, the depth is 840mm or 1040mm, and the height is 2300mm (excluding the outer packaging and outer dimensions.
    The installation should be carried out according to the schematic diagram (see FIG. 3). If the cable goes out, the external dimensions of the cable trench should be carried out according to FIG. 4.
     The installed foundation plane shall be flat, the horizontal error of the foundation channel steel shall be 1/1000, and the total length deviation shall be ±3mm.
     During installation, the main bus connection should be made according to the drawings, and the surface of the main bus should be cleaned, and then tightened with bolts, and cable or overhead wire wiring work
     When the rated current of the busbar bridge is 5002500A and the middle net span is greater than 2500mm, a sling shall be installed between the roofs of the power distribution room in the center of the bridge. See Figure5.

 

• The frame of the device is a combined structure, and the basic skeleton is assembled by a c-profile with a modulus of e=20, and is fastened by a self-tapping locking screw or a 8.8-level hex bolt to form a basic frame, and a door corresponding to the change of the scheme, The partition, the sealing plate, the mounting bracket and the busbar functional unit are assembled into a complete device, which has high mechanical strength, no deformation of the single cabinet, and an open shape of the profile steel, which easily achieves the purpose of pre-treatment.
• The cabinet is divided into three compartments, namely the horizontal busbar compartment (at the rear of the cabinet), the functional unit room (at the front of the cabinet), the cable compartment (in the lower part of the cabinet or the front of the cabinet), and the chamber and chamber supports are plated. The zinc plate or the high-strength flame-retardant plastic function board are separated from each other, and the functions of the respective chambers are relatively independent; the metal plates with ventilation holes between the upper and lower drawer functional units are isolated to effectively prevent the arcing of the electrical components from being short-circuited with the busbar or other lines due to malfunction. The accident caused.
• The horizontal busbar adopts the rear arrangement of the cabinet to increase the capacity of the busbar to resist electric power, so that the main circuit of the device has high short-circuit strength capability.
• Classification of incoming and outgoing lines: up and down, up and down, down and down, down and up.The cable compartment is designed to make it easy to access the cable up and down.
• The short-circuit strength value of the main structure reaches the rated short-time withstand current of 80ka and the rated peak withstand current of 176ka, which can match the current and future transformer capacity (2500kva).
• A large number of new and more reasonable structural parts and components have been used in large quantities, and special parts are mass-produced by dedicated factories to ensure quality and standardized production.
• In order to reduce the temperature rise of the connector, cable head and partition plate of the functional unit, the special adapter for the gcs cabinet is designed. Compared with similar products, the heat capacity is increased and the temperature rise is reduced.
• The device is designed according to three-phase five-wire system or three-phase four-wire system. The design department and users can conveniently select pe+n or pen mode.
