What Is The Place To Be Noticed In The Use Of Stainless Steel Optic Distribution Frame?

What is the place to be noticed in the use of stainless steel Optic Distribution Frame?
1, construction electricity distribution system should set the total Optic Distribution Frame, sub-Optic Distribution Frame, switch box, and in accordance with the total separation of the order as a set, and the formation of three power distribution mode.
2, the construction of the distribution system Optic Distribution Frame, switch box installation location should be reasonable. Total Optic Distribution Frame should be as close as possible to the outside of the transformer power supply, to facilitate the introduction of power. The distribution box should be installed as much as possible in the center of the electrical equipment or the relative concentration of the load to ensure that the three-phase load is flat. The location of the switch box should be set according to the situation and construction of the site.
3, to ensure that the temporary electricity distribution system three-phase load balance, the construction site of power and lighting power should be the formation of two electricity circuits, power Optic Distribution Frame and lighting Optic Distribution Frame were set.
4, the construction site of all electrical equipment must have their own dedicated switch box.
5, all levels of stainless steel Optic Distribution Frame of the box and the internal settings must meet the safety requirements, switching appliances to mark the use of the box to be unified number. Stop the use of stainless steel Optic Distribution Frame should be cut off the power, lock the door. Fixed Optic Distribution Frame To set up the fence, and have anti-rain anti-smashing measures.
6, stainless steel Optic Distribution Frame are generally used in the family, and distribution cabinets for centralized power supply, are generally industrial and construction electricity, stainless steel Optic Distribution Frame and distribution cabinets are all complete sets of equipment, stainless steel Optic Distribution Frame is a low-voltage complete sets of equipment, power distribution cabinets are high pressure low pressure.
The price of stainless steel Optic Distribution Frame is generally divided into two parts, part of the price is empty box, mainly based on personal use of a few road electricity, set the size after there will be a price. The other is inside the switch, protector and other prices, quality is also good or bad, so we need to buy stainless steel Optic Distribution Frame, you can go to the local hardware market to see, the general price of stainless Optic Distribution Frame are a few 100 yuan, and stainless steel Optic Distribution Frame is also divided into power Optic Distribution Frame and lighting Optic Distribution Frame two, is the final power distribution system equipment. Stainless Optic Distribution Frame Assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet according to the electrical wiring requirements.
Ambient temperature on the impact of low-voltage electrical equipment caused by the failure, Optic Distribution Frame in the low-voltage electrical appliances, by the fuse, AC contactor, residual current action protector, capacitors and meters and other components. These low-voltage electrical appliances are according to GB1497 "low-voltage electrical basic standards" for the design and manufacture, and their normal working conditions are specified: the ambient air temperature of the upper limit of not more than 40 ℃; ambient air temperature 24h average of not more than 35 ℃ ; The lower limit of the ambient air temperature is not lower than -5 ° C or -25 ° C. The Optic Distribution Frame, which is retrofitted by the rural power network, runs outdoors and is not only exposed to direct sunlight. At the same time, the heat will be generated during the operation. Therefore, during the hot summer season, the temperature inside the box will reach above 60 ℃. The temperature is much higher than the ambient temperature specified by these appliances, which will occur due to Optic Distribution Frame electrical components caused by overheating failure.
Product quality caused by failure in the rural power grid transformation at the time due to the demand for the Optic Distribution Frame large number of construction period is short, Optic Distribution Frame plant needs low-voltage electrical supply time and the number of urgent and quantity, resulting in the product quality requirements Strict phenomena, resulting in a number of products put into operation shortly after the failure. If some models AC contactor in the Optic Distribution Frame put into operation soon after, because the contactor closing coil burned, and can not run. The same time as
Optic Distribution Frame Improper selection of electrical appliances Due to improper selection of AC contactor capacity at the time of manufacture, an AC contactor with the same capacity is installed for different outlet circuits without taking into account the imbalance of the three-phase load. Can be part of the outlet contactor current rating in the normal selection model based on the increase in a current level selection, resulting in the summer hot season operation when the AC contactor burned out of the situation.
