You can not add each loop between the cabinet and isolation measures can also be used a grounded metal plate or insulating plate isolation. Usually the main door switch operation with a mechanical interlock. There are also shielded station switchgear (ie the console), the panel is equipped with control, measurement, signal and other electrical appliances. Protective switchgear is mainly used for craft-site power distribution equipment. (3) switch cabinet drawer. Such switch cabinet with sheet steel enclosure, inlet and outlet circuit electrical components are mounted on extractable drawer, constitute a class-powered task to complete functional unit. Between functional units and bus or a cable, use a grounded metal plate or plastic apart, forming the bus, functional units and three regional cable. There isolation between each functional unit. Switch cabinet drawer with high reliability, security and compatibility, is more advanced switchgear, switchgear current production, the majority of switch cabinet drawer. They are suitable for industrial and mining enterprises require high reliability of power supply, high-rise buildings, as centralized control of the distribution center. (4) power, lighting distribution control box. Mostly enclosed vertically. Due to the use of different occasions, shell protection grade is different. They are mainly used as industrial and mining production site power distribution unit power distribution panel (box) Install the power distribution panel (box) installation requirements are: distribution panel (box) Application of non-combustible material; shock hazard small production sites and offices, can be installed open style switchboard; in large shock hazard or poor operating environment processing plant, casting, forging, heat treatment, boiler room, woodworking room and other places, enclosed cabinet should be installed; in conductive dust or dangerous workplaces produce flammable gases, must be installed closed or explosion-proof electrical facilities; switchboard (box) All electrical components, instruments, switches and lines should be arranged in neat rows, installation firm, easy to operate. [1] [2] [3] [4]; cardboard (box) the bottom surface of the floor should be installed above ground 5 ~ 10 mm; operating handle center height is generally 1.2 ~ 1.5m; cardboard (box) in front of 0.8 ~ 1.2m no obstacle within range; reliable protection cable; other than cardboard (box) shall not have bare charged body exposed; it must be installed on the board (box) or the outer surface of the electrical components of the power distribution panel, must be a reliable screen protection. Power Distribution Board (box) runs a distribution panel (box) within each of the electrical components and wiring should be in good contact, reliable connection; not have serious fever, burning phenomenon. Power Distribution Board (box) of doors should be intact; locks should someone custody. A circuit diagram of a circuit diagram of the power distribution cabinet distribution board distribution board is divided into a diagram, the second a schematic diagram that is the main circuit diagram. The second is the principle of the schematic diagram of the control circuit intelligent integration of power distribution cabinet (Figure) relative to the previous distribution cabinet intelligent integration of these distribution cabinet made a big improvement! It is a technological innovation! In allusion to current distribution room prone to single point of failure, integration of today's most advanced techniques and hardware and software design in one. Distribution room dedicated to the construction and management to bring a new experience, mainly used in finance, telecommunications, business, government and other data center and computer room, in capacities ranging from 30KVA-160KVA. The whole distribution system uses a standard network cabinet and modular design, with a wealth of options, according to the actual needs of room for customized personalized high reliability products. Intelligent Power Distribution Cabinet real-time monitoring of each output current shunt, shunt current output can be set for each pre-warning of abnormal values, such as 16A switch, set the alarm value of 14A, 14A on the load exceeds the alarm can be pre-found fault or manual operation risks, to avoid overload, switch off the power, causing the entire cabinet units off. Also Output channel selection hot-swappable circuit breakers, have the ability to take power phase adjustment, easy 3-phase unbalanced flexibility to adjust, but also in the case of UPS, on-line to increase output shunt, switching replacement. Intelligent integration of power distribution equipment product also features prominent feature of large-screen LCD touch screen, voltage, current, frequency, useful power, useless power, energy, harmonics and other power quality and do all the monitoring. Users of the computer room power distribution system operation status at a glance, to facilitate early detection of safety problems, as soon as possible to avoid risks. In addition, users can also choose ATS, EPO, lightning protection, isolation transformers, UPS maintenance switch, the electricity output branch and other functions, to ensure the security and stability of the power distribution system of the engine room. First, the distribution cabinet distribution hub for the normal operation of the ship and eight production facilities, no unauthorized personnel can not flip the board switchgear cabinet rules. Second, the generators start, dynamic screen upshift switch manually should use slow acceleration, until the generator into the normal working state, the voltage and frequency reaches a predetermined value, before closing transmission. Third, the power distribution board into the distribution state, are not free to Stubbs dynamic screen upshift switch, air circuit breaker lockout switch may not be used for non-emergency situations. Fourth, the generators parallel operation in strict accordance with the provisions and requirements of vehicle operating conditions, should pay attention to when reverse power (counter) and vehicle failure and so on. Fifth, it should be shut off before the generator load and no-load stop, can not stop with a load directly. Sixth, when interleaved shore power, you should cut off the shore screen each power switch, then check the wiring and the correctness of the phase sequence to confirm correct, before the implementation of the ship shore power conversion, non-band responsible for the operation. Seven distribution cabinet should be cleaned regularly and maintenance work so that equipment is always in good working condition. Eight, a generator, switchboard staff during turbine operation, should focus thinking, exercise caution to prevent accidents, or they will be held personally responsible for the accident. Nine, charge and discharge board for the ship's emergency switchboard, duty engineer should always check the status of their work, at any time to ensure adequate low-voltage electricity, and grasp the instrument panel by magnetic saturation regulator working conditions. Ten, when the normal navigation, power switch should be in the on-board and the brightest to ensure that the generator can be activated at any time and should be supervised at all times be able to put to use.
