The distribution box is a massive parameter on the data. It generally constitutes a low-voltage forest and is electrically connected. The switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are required to be assembled in a closed or semi-enclosed metal cabinet or on a screen, forming a low-voltage distribution system. box. During normal operation, the circuit can be switched on or off by means of a manual or automatic switch. Commonly used distribution boxes are made of wood and metal, because metal distribution boxes have higher protection levels, so they are still more used for metals. So, do you understand the working principle of the resident distribution box ? What are the specifications of the household distribution box ? If you are interested in this, you may wish to follow me to learn about it!
Household distribution box use
Reasonable distribution of electrical energy facilitates opening and closing of circuits. It has a high degree of safety protection and can intuitively display the conduction state of the circuit.
Household distribution box principle
The distribution box is to assemble the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in enclosed or semi-enclosed metal cabinets or screen panels according to the electrical wiring requirements to form a low-voltage distribution box. During normal operation, the circuit can be switched on or off by means of a manual or automatic switch. In the event of malfunction or abnormal operation, the circuit or alarm is cut off by means of a protective appliance. Measurement instruments can be used to display various parameters in operation, and certain electrical parameters can also be adjusted to indicate or signal deviations from normal operating conditions.
Household distribution box size
In general, the approximate size of the distribution box is specified in the design. When customized, the size of the distribution box may not be used. The dimensions provided by the design are for reference only. The dimensions of the box are also indicated on the drawings for reference only. According to different products and on-site construction needs to modify the size of the box, the design does not need to change. Although it is a reference size, designers should be aware of the size of the box. This can avoid too many boxes and design time differences during construction, causing unnecessary trouble.
The following is the method of estimating the box when I was doing the design. I can refer to the landlord for reference. The calculated size of this method will generally be larger than the actual size.
1. When the electrical box is only a light box or small power, when the incoming line is less than 10 squares, if the number of switch bits is less than 20, the switch width size adds up and then adds 20 MM to each side as the width of the electrical box, and the height is the switch height. Plus 40MM, the depth of the switch plus the maximum depth of 10MM.
2 When the electric box is only a lighted box or small power, when the incoming line is less than 10 squares, if the number of switch digits is greater than 20, then the electric box needs to be arranged as two rows of switches, and the switch width size adds up and then adds 40 MM to each side. For the width of the box, the height of the switch is 40 mm, and the depth is the maximum depth of the switch plus 10 mm.
3 When the electric box is only the lighting box or small power, when the incoming line is less than 10 square, if the incoming line switch needs a separate row, the width of the switch adds up and adds 20 MM on each side to the width of the electric box, and the height is the height of the switch. Plus line switch height plus 40MM, depth is the maximum depth of the switch plus 10MM.
4 When the electric box is a power box, or when the power is lighting the box, the algorithm is basically the same as the above, but when the incoming line is larger than 10 squares, the bending radius of the incoming line must be taken into account. Lines, when two rows of switches are arranged, the wiring of the switches should be considered.
Of course, the size of the electrical box is inconclusive. The actual installation must be considered. It depends on the actual wiring diagram and considering how to arrange the switch to route the primary switches.
If all miniature circuit breakers are determined based on the number of digits (each 18 mm), the PZ series distribution box has a fixed size, and the loop exceeds 80 digits. It can be identified on the drawings (Part 1). The equipment control box identification equipment comes with The line is larger than 185mm2, and the output is greater than 2 ways.

Ball lens are highly transparent spheres made of optical glasses.They are used as fiber interconnects in telecom and expanded beam connectors.Large ball lenses have been successfully used as collectors in LED lighting systems and medical devices.They have high coupling efficiency and should be much easier to align than traditional lenses due to its physical shape.Fused silica balls are ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Sapphire balls has superior optical transmission qualities. Ruby Balls are easier to see and therefore easier to handle for physical applications.
Half ball(hemispherical)lenses are ideal for applications such as fiber communication,endoscopy,microscopy,optical pick-up devices and laser interferometry and measurement.
