Changshu, Chint, West Germany XRM stainless steel distribution cabinet Henan Luo Xin Electric

A power distribution device, referred to as the power distribution center. They focused on companies installed in the substation, the distribution of electricity to lower distribution equipment in different locations. This level of equipment close to the step-down transformer, so the higher the electrical parameters required, the output circuit capacity as well. (2) secondary distribution equipment, power distribution cabinet is collectively and motor control centers. Power distribution cabinet use in load scattered, small loop occasions; motor control center for centralized load loop more occasions. They allocated on a circuit-level power distribution equipment to the nearest load. This level of equipment to deal with load protection, monitoring and control. (3) The final distribution equipment referred to lighting power distribution box. They are far from the power centers are scattered small-capacity power distribution equipment. By structural features and usage: (1) fixed panel switchgear, often called the switch board or power distribution panel. It is a kind of masking panel open switchgear, positive protective effect, back and side still touching the live, low degree of protection can only be used for power supply continuity and reliability requirements of low industrial and mining enterprises, as centralized power supply with a transformer room. (2) Protection of formula (ie, enclosed) switchgear, refer to the mounting surface in addition, all other sides are closed up in a low-voltage switchgear. Such a switch cabinet, protection and monitoring control and other electrical components are installed in a steel or enclosure made of insulating material, it can be installed against a wall or away from the wall. 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 field distribution equipment related installation edit this section switchboard (box) installation requirements are: distribution panel (box) Application of non-combustible material; shock hazard small production sites and offices, can be installed Open type switchboards; in big danger of electric shock 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 easily produced burning explosive gases hazardous workplace 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. ; Floor plate (box) should underside of 5 ~ 10 mm above ground installation; operating handle center height is generally 1.2 ~ 1.5m; cardboard (box) is no obstacle in front of the range of 0.8 to 1.2m; the protective conductor connection is reliable; cardboard (box) shall not have bare live outside the body exposed; it must be installed in the board (box) or the outer surface of the electrical components of the power distribution panel, must be a reliable screen protection. Here's a simple and tell you about some of the electrical components of the installation process. Component Installation 1 premise: All components installation conditions specified by the manufacturer shall be installed. Conditions: distance required extinguishing the arc chute removal space required, etc., for a manual switch installed, you must ensure arc switch operator is not dangerous. First look at next assembly of the first two drawings and technical requirements; 3 Check product model, component models, specifications, quantity and drawings are matched; 4 Check components for damage; Fig. 5 must be installed (if there are pictures); 6 yuan Device assembly sequence, as the front panel should be, from left to right, top to bottom; 7 of the same types of products should ensure consistency assembly; 8 panels, door panels centerline height element shall comply element name of the installation height (m); instructions instrumentation, electrical measuring instruments 0.6-1.8 0.6-2.0 lights control switches, buttons 0.6-2.0 0.8-1.6 emergency operation member assembly products should meet the following conditions: 1) easy to operate. Component In operation, should not be hinder space should not be possible to touch live parts. 2) ease of maintenance. Can more easily replace components and repair connections. 3) clearances of various electrical components and devices, creepage distances shall comply with the provisions of 4.4. 4) ensure the installation from the one or two lines. 9. The assembly of fasteners and metal parts used should have a protective layer on the screw through the hole, burrs and surface edges, spikes should be polished smooth before applying a conductive paste. 10. For the fastening bolts should select the appropriate tools, fasteners must not destroy the protective layer, and pay attention to the appropriate torque. 11. The main circuit above components, generally reactors, transformers need grounding, circuit breakers do not need to be grounded. Distribution cabinets from China trading network basically running Edit this paragraph switchboard (box) electric 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. Switchboard schematic circuit diagram of the power distribution board 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.
