Specific implementation mode
Below in conjunction with the attached drawing of the utility model, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation describes.
A kind of anti-electromagnetic interference power distribution cabinet of secondary circuit, including cabinet 1 are divided into inside the cabinet 1：2 between inlet wire, break
3 between the device of road, 4 between outlet, 5 between secondary device：
Between the inlet wire between 2 and the breaker 3 be arranged side by side, 3 top is set between 2 and the breaker between the inlet wire
Have 5 between the secondary device, between the outlet 4 between the inlet wire between 2 and the breaker 3 the back side；
3 are being equipped with upper and lower perforative secondary line slot 6 close to the side of cabinet 1 between the breaker；The secondary line
Slot 6 is made of aluminium or copper or steel, and section is hollow structure, and 6 side of secondary line slot offers threading hole 7, described
Vertically-mounted breaker in 3 between breaker；
5 bottom is shielding partition panel 8 between the secondary device, and shielding partition panel 8 is made of aluminium or copper or steel, the screen
It covers partition panel 8 and is equipped with several ventilation holes 81, one metal wire layer 82 is covered on the ventilation hole 81.
Secondary device in power distribution cabinet is installed concentratedly 5 between the secondary device, and secondary line enters two by threading hole 7
In secondary line slot 6, secondary line slot 6 is passed through from inside, is then connect between the secondary device 5 secondary device.
Meanwhile between secondary device 5 and primary circuit where inlet wire between 2,3 between breaker, 4 are opened with the shielding partition of partition panel 8 between outlet.
Partition panel 8 and secondary line slot 6 are shielded by having the aluminium of prodigious reflection loss, copper or steel to be made to electromagnetic wave.
The heat dissipation that the ventilation hole 81 on partition panel 8 is convenient for primary circuit is shielded, in order to avoid these ventilation holes 81 become electricity
The approach of magnetic dispersion is covered in 82 net of wire on ventilation hole 81, can significantly increase shield effectiveness, and simple in structure,
It is of low cost.
