The assembly standard of distribution equipment board (box) is: the distribution equipment board (box) is made of non flammable materials; Open distribution equipment boards can be assembled in manufacturing sites and company offices with small risk factors of electric shock accidents; The closed cabinet shall be connected in the production and processing workshop, casting, forging, heat treatment process, boiler room, carpenter's room and other places with large risk factors of electric shock accidents or poor working natural environment; In the hazardous operation site with conductive smoke and dust or with combustible and explosive waste gas, it is necessary to assemble enclosed or explosion-proof power equipment; All electrical components, instrument panels, power switches and routes of the distribution equipment board (box) shall be orderly, firmly assembled and convenient for practical operation. The bottom edge of floor mounted plate (box) shall be 5 ~ 10mm higher than the road surface; The relative height of the control rod core is generally 1.2-1.5m; There is no obstacle within 0.8-1.2m in front of the plate (box); Maintenance line connection is reliable; There shall be no bare transmission line exposed outside the board (box); The electrical components and parts placed on the outer surface of the board (box) or the distribution equipment board must have stable screen protection.
All electronic components and routes in the power distribution equipment board (box) shall have good touch and reliable connection; There shall be no serious burning and ablation. The door of distribution equipment board (box) shall be intact; Anti theft locks should be stored by full-time personnel.
The circuit schematic diagram of the distribution equipment board is divided into primary circuit schematic diagram and secondary circuit schematic diagram. The primary circuit schematic diagram is the main circuit design diagram. The secondary circuit schematic diagram is the circuit schematic diagram of the control circuit.
For the current situation that the power distribution equipment in the main engine room is very easy to cause server downtime, it integrates the excellent scientific and technological achievements and hardware and software development of Z. Focusing on the construction and supervision of power distribution equipment in the main engine room, it has a brand-new upgrading feeling. It is mainly used in the financial industry, telecom network, companies, government departments and other big data centers and main engine rooms. The volume range is 30kva-160kva. All power distribution systems are designed with standardized server cabinets and modular design, equipped with sufficient spare parts, which can be customized for customers according to the real needs of the data center.
The intelligent distribution box real-time monitors the current quantity of each lead-in and can set the pre alarm value of each lead-in current quantity. For example, if the 16A power switch is set with the alarm value of 14a, the alarm will be given when the load exceeds 14a. Common faults or hidden dangers of manual actual operation can be found in advance, so as to prevent the power switch from disconnecting the switch power supply when the load is on, resulting in the shutdown of all server cabinet machines and equipment. In addition, the hot plug disconnector is adopted for the lead-in separation, which has the ability to adjust the phase difference of power supply. It can easily adjust the three-phase imbalance. It can also lift the lead-in separation online and carry out the power switch replacement under the condition of continuous power supply.
