Description

Technical field:

[0001] The invention belongs to the field of compensation equipment, in particular to a highly intelligent harmonic elimination and filtering compensation equipment with multiple safety protections. Background technology:

[0002] The harmonic elimination device is a passive filter device specially used for harmonics of the 3rd, 5th, 7th, 11th, 13th and above in low-voltage power grids. It is suitable for medium-frequency smelting, frequency conversion, steel rolling, rectifier equipment and other environments. The device uses inductors and capacitors to form a series resonant absorption circuit to effectively absorb the harmonics generated by the load, thereby avoiding the return of harmonic current to the power transformer, greatly reducing the harmonic amount of the power grid, and at the same time is beneficial to the operation of the user's power transformer, reducing power consumption, and improving the reliability of equipment and other electrical components.

[0003] However, the existing detuning device is usually directly fixed inside the electric control box during assembly. Although the structure is relatively compact, the existing electric control box does not have a shock-absorbing function, and cannot protect the equipment well during use. In addition, there is no detection device inside the electric control box, and the user cannot monitor the equipment in real time, which increases the difficulty of use. When the existing electric control box is dissipating heat, a fixed fan is usually used to discharge the hot air inside the electric control box to the outside. This heat dissipation efficiency is relatively slow, and good heat dissipation cannot be performed, which has a certain impact on the service life of the equipment. Summary of the invention:

[0026] Among them, a protective pad 8 is fixedly connected to the inner wall of the installation box 1 and located just above the installation plate 5, so as to facilitate the protection of the filter capacitor 6 and the filter reactor 7.

[0027] Among them, a second slide groove 9 is opened on both sides of the inner wall of the installation box 1 and directly above the installation plate 5. The second slide groove 9 is slidably connected to a cable organizer 10, which can organize the wire harness inside the installation box 1, which is beneficial to keeping the interior of the installation box 1 tidy, and is convenient to move, thereby improving the flexibility of use.

At the same time, the indicator light 21 turns red, thereby prompting the staff to maintain the equipment. The inside of the installation box 1 can be dehumidified by the adsorption box 14 in combination with the medicine box 15. When the material inside the medicine box 15 needs to be replaced, the iron sheet 17 is separated from the magnet 16 by pulling the handle on the medicine box 15, and then the medicine box 15 is cleaned and filled with new dehumidifying materials. Then the medicine box 15 is inserted into the adsorption box 14 again, and the position of the medicine box 15 can be fixed by the cooperation of the magnet 16 and the iron sheet 17.
