equipment distribution box enclosure Introduction:
LWHG series distribution box is a kind of modularized apperance with small volume industrial electrical box. Based on the advantages of being easy to install, it has excellent strucure and higher performance,and it's widely applied in building electrical distribution system's installation, industrial
electrical circuit and house rebuild fitment etc.
1, equipment distribution box enclosure should be installed and consolidated, conducive to the actual operation and maintenance.
2. For the distribution box and switch box installed on the floor, the setting address should be flat and higher than the road surface, and the surrounding dirt should not be piled up.
3, three-phase five line port and group outlet should be built at the bottom or side of the box, the transformer grounding line of the switching power supply should be routed pipe and waterproof elbow pipe.
4. The transmission line in the box should be well insulated, orderly, fixed and consolidated, and the edge of the transmission line should be connected with screws or sockets.
5. The distribution box with 3 control loops shall be equipped with general switch and separate switch. Each branch knife switch should not be connected to two or more electrical equipment, should not be used for two or two operating groups.
6, lighting fixtures, driving force of the distribution box should be installed separately switch or other types of power switch.
7, distribution box, switch box installed in communication contacter, switch, power switch and other electrical equipment, should posture is convenient, good touch spectrum, circuit breaker has no more serious gap corrosion.
Equipment Distribution Box Enclosure manufacturers for distribution box moisture commonly used dehumidification methods have the following ways:
1. Electric heater is installed in the box to heat the inside of the equipment. After improving the temperature in the box, the relative humidity in the box is reduced.
2. The box is equipped with damp repellent, and the silica gel bag or other water absorbing material is hung in the box to absorb the moisture in the box.
3. The fan is installed outside the box to reduce the humidity in the electrical box by alternating with the dry air outside through the convection of the air.
4. Use cement to seal the gap between the inlet and outlet cables, and seal the cabinet door with sealing rubber strip.
Electric heater is used to heat the inside of the equipment to deal with the condensation phenomenon, but this method can not basically eliminate condensation, because this method only increases the unsaturated level of water vapor in the air, and does not discharge the water vapor in the box; With the flood agent, hanging silica gel bag in the box, or other water absorption material, but because of its water absorption effect is limited, and the absorption of water is difficult to discharge, so the effect is often not obvious, the maintenance workload increases; With the fan, through the convection of the air and the dry air outside to reduce the humidity in the electrical box, the environmental humidity is large, it does not work, it is easy to form the formation of dust, pollution into the damp proof purpose can not be completed.
Anti-condensation installation is based on the dehumidification management of long-term humid air in the power Equipment Distribution Box Enclosure, and according to the small volume, portable device design criteria, modular structure design. The dehumidification method adopts semiconductor refrigeration technology, and the relative humidity in the box is reduced under some manufacturing conditions of condensation, and the condensed water is directly discharged. The AC-DC wide - range switching power module is also used to supply power to ensure that the installation works properly at a lower ambient temperature. Device standard is ** insulation interval. Laying drainage pipe, all the dehumidification installation of condensate water can be gathered and discharged outside.
The top dehumidification is installed on the basis of the above technology, taking into account the distribution box equipment internal space compact, high environmental humidity, perfect interval and other factors and developed products. The shell is made of high-power and high-strength aviation aluminum. This installation is the top device, using ultrasonic atomization technology, forced atomization of condensed water isolation discharge.
