PGL AC low-voltage distribution panel (hereinafter referred to as the power distribution panel), as AC 50Hz, rated voltage 380V and below the low-voltage power distribution systems, power distribution, lighting purposes for power plants, substations, industrial enterprises. The power distribution panel indoor installation, low voltage distribution equipment for the open-sided maintenance. Product distribution panel edit basic structure of the present section with sheet steel and angle iron welded combination. Front screen door. Screen surface side instrument panel, the door can be opened, can be installed indicating instrument, easy maintenance. A combination of parallel assembly of screen, add a separator between the screen and reduce the possibility of the expansion of the accident. After the main bus mounted above the screen, and a bus shield to prevent falling over the metal and cause a short circuit the main bus. Distribution panel has a good grounding protection system, the main access point for welding in the skeleton underneath, instrument door is also interconnected with the housing ground. Neutral bus device in the bottom of the screen on the insulator. Company Website: http: //www.henanluoxin.com multi-screen when side by side, the left and right ends of the screen and start a terminal screen, the installation shield. 400,600,800mm size distribution panel screen width and 1000mm of four, each screen can be used as a stand-alone unit and can screen for the unit composed of a variety of different programs. ◆ Category Edit this paragraph are generally divided into low voltage distribution panel, high voltage power distribution panel and DC power distribution panel, AC distribution panel. Low-voltage distribution cabinet Product Category GCS type low voltage distribution cabinet is designed according to the two joint design team the majority of electricity users and design units to develop products in line with national conditions, with high technical performance, able to adapt to the development needs of the electricity market. Low-voltage power distribution equipment for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries, as the transmission, distribution and conversion of electric energy use. Products comply with IEC439-1, GB7251.1-1997 "Low-voltage switchgear" of standards. Low-voltage distribution cabinet adopted the national 3C certification. Distribution screen distribution panel ◆ GCS type low voltage distribution panel GCK (L) low voltage distribution cabinet application Edit this paragraph GCS type low voltage distribution panel are two joint design team, according to industry authorities, the majority of electricity users and the design requirements for unit design developed in line with national conditions, with high technical performance, able to adapt to the development needs of the electricity market and introduce products to compete with existing low voltage distribution panel. The low-voltage power distribution panel has been widely electricity users to choose. Low-voltage distribution panel for power plants, petroleum, chemical, metallurgy, textile, high-rise construction industry distribution system. High degree of automation in large-scale power plants, petrochemical systems, computer interface requirements and place, as a three-phase AC frequency of 50 (60) Hz, rated voltage of 380V (400), (660), rated current 4000A and below hair, power distribution systems, motor centralized control, low voltage power distribution equipment used for reactive power compensation. Low-voltage distribution panel is designed to meet the following standards IEC439-1 "Low-voltage switchgear and control equipment" GB7251 "Low-voltage switchgear" JB / T9661 "Low-voltage withdrawable switchgear" Second, the model and the meaning Third, the use of environmental conditions surrounding air temperature not higher than + 40 ℃, not lower than -5 ℃. 24-hour average temperature not higher than + 35 ℃. More than is required to run the actual situation derating. Indoor use, place of use Altitude should not exceed 2000m. Ambient air relative humidity at the highest temperature is + 40 ℃ not more than 50%, at a low temperature allows a greater relative humidity: As at + 20 ℃ 90%, should take into account changes in temperature may occasionally produce condensate Lu impact. Low-voltage distribution panel installation and the vertical gradient of not more than 5 °, and the entire group is relatively flat cabinet column (in line with GBJ232-82 standard). Low voltage distribution panel should be installed in the absence of severe vibration and shock, and enough to make electrical components should not be corrosion sites. Users have special requirements, can be resolved through consultation with the manufacturer. Fourth, the main technical parameters of the basic technical parameters of five, low-voltage distribution panel characteristics increase the heat capacity of the adapter, a more substantial reduction in temperature rise due to the additional adapter to the connector, cable head, spacer plate brought . Between the functional units, the partition between the compartments clear, reliable, due to failure of a unit without affecting the other units of work, limited to a minimum so that fault. Bus flat-mounted arrangement enables the dynamic low voltage distribution panel, good thermal stability, can withstand 80 / 176kA short circuit current impact. Number of single cabinet MCC cabinet circuit 22 times more to take full account of the large stand-alone capacity power generation, petrochemical and other industries automation electric gate (machine) group needs. Low-voltage distribution panel and external connection cables in the cable compartment is completed, the cable can be up and down and out. Zero sequence current transformer set cable compartment makes installation and maintenance. The same power distribution system, it can match by limiting short-circuit current limiting reactors, bus voltage stable at a certain value, but also reduce the component parts of the short-circuit strength requirements. Drawer unit has a sufficient number of secondary connectors (1 unit and up to 32 pairs, Unit 20 in.) To meet the computer interface and automatic control loop requirements on the number of contacts. Sixth, the use of low-voltage distribution panel precautions not to wall installation, front operation, maintenance of low-voltage distribution cabinet duplex. Cabinet and maintenance access doors, the assessment must be qualified professionals to enter or open operation, inspection and maintenance. Air circuit breakers, molded case circuit breaker after several hours together, especially after short-circuit, after closing, will contact local burn and produce carbon-based material, the contact resistance increases, should breaker Instructions for maintenance and repair. After installation and maintenance, must be strictly checking between each compartment, segregation between functional units, in order to ensure that the low-voltage distribution panel good functional compartmentalization to prevent the failure to expand. Seven, after product installation inspection and test and inspect the cabinet paint or other covering material before operation (such as spray) for damage, whether inside dry and clean. Electrical components of the operating mechanism is flexible, there should Jamming phenomenon of excessive force or operation. Major appliances off the main and auxiliary contact is reliable and accurate. Drawer pull or draw-out mechanism should be flexible, lightweight, no jamming and collision phenomenon. Fixed drawer or out of structure, the center line of static contact should be consistent, should contact contacting tight. Primary and secondary contact insertion depth should meet the requirements. Mechanical interlocking or electrical interlocks action should be correct, lock or unlock should be reliable. The same size drawer can easily be interchanged without jamming and collision phenomenon. Ground contact between the drawer and the cabinet should be in close contact, when the drawer is pushed, the drawer ground contacts after the main contacts first contact with the ground contact than after the main contacts to open when pulled. Instrument calibration tuning, transformer turns ratio and polarity should be correct. Fuse fuse specifications should meet the engineering requirements. Protection rating and setting should be correct and reliable operation. 1000 Megohmmeter measure the insulation resistance of not less than 1mΩ. Connecting the bus should be well insulated supports, installation pieces and other accessories installation should be strong and reliable.
