Embodiment 1

[0044] A dust removal device for reducing the power failure rate of electric equipment maintenance, comprising a first dust removal mechanism, a power conversion mechanism connected to the first end of the first dust removal mechanism, and a first dust removal mechanism connected to the second end of the first dust removal mechanism. The regeneration mechanism, the settling mechanism connected with the energy conversion mechanism, the dust accumulation module arranged at the lower part of the settling mechanism, the absorbing mechanism arranged at the rear of the settling mechanism, and the discharge mechanism 11 arranged at the upper part of the absorbing mechanism , a circulation mechanism connected with the absorption mechanism, a discharge module arranged at the lower part of the absorption mechanism, and an adsorption filter mechanism 23 arranged between the absorption mechanism and the discharge mechanism;

[0045] The first dust removal mechanism includes a plurality of ...

Embodiment 2

[0056] Embodiment 2, which is different from Embodiment 1 in that: the regeneration pipeline 2, the regeneration discharge pipe 21, and the first air intake pipe 22 are all equipped with a detection module 19;

[0057] The detection module 19 includes a flow rate sensor 192 , a dust sensor 191 and a temperature sensor 193 .

[0058] The first regeneration mechanism adopted in this embodiment includes a regeneration pipeline communicated with the discharge mechanism, solenoid valves arranged at both ends of the regeneration pipeline, a regeneration supercharger arranged in the middle of the regeneration pipeline, and a The regeneration discharge pipe at the lower part of the dust collector; the airflow can be pressurized by the regeneration supercharger to ensure that there is a high-speed airflow to clean the dust collector during back-blowing and dust removal, which can greatly reduce the amount of back-blowing gas and ensure The effect of overall cleaning; the energy convers...

Embodiment 3

[0059] Embodiment 3: The difference between it and Embodiment 2 is that: the first dust removal mechanism, the energy conversion mechanism, the first regeneration mechanism, the sedimentation mechanism, the dust accumulation module, the absorption mechanism, the discharge mechanism, the circulation mechanism, and the unloading module are all compatible with The signal interconnection of the control modules arranged on the outer wall of the dust collector;

[0060] The control module is PLC or personal computer.

[0061] The adsorption turntable includes two ring-shaped sealing plates 231, a cylindrical channel 232 that is arranged between the two ring-shaped sealing plates 231 and matches the discharge pipe, and connects the mandrel 237 with the ring. A plurality of support arms 233 between the shaped sealing plates 231;

[0062] The adsorption module is arranged in the cylindrical channel 232, and the sealing ring 235 matched with the annular sealing plate 231 is arranged on...

Abstract

The invention discloses a working method capable of lowering outage rate during electrical equipment overhaul. The working method comprises a first dust removal mechanism, a transducing mechanism communicated with a first end of the first dust removal mechanism, a first regeneration mechanism communicated with a second end of the first dust removal mechanism, a settlement mechanism communicated with the transducing mechanism, a dust deposition module arranged at the lower part of the settlement mechanism, an absorption mechanism arranged at the rear part of the settlement mechanism, a discharge mechanism arranged at the upper part of the absorption mechanism, a circulating mechanism communicated with the absorption mechanism, a discharging module arranged at the lower part of the absorption mechanism and an adsorption filtration mechanism arranged between the absorption mechanism and the discharge mechanism. Under the synergistic interaction of all the modules, not only is waste gas efficiently recycled, but also substances in the waste gas can be recycled, so that pollution to the environment is avoided, and the phenomena that an existing dust removal system can not efficiently utilize waste and the waste gas enters into natural environment can be avoided.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance equipment, in particular to a working method for reducing the power failure rate of power equipment maintenance. Background technique [0002] According to incomplete statistics, at present, electrical equipment failures caused by external environment changes account for 62% of the overall equipment failures, design and device defects account for 18%, use and maintenance factors account for 11%, and other factors account for 9%. External environmental factors have become one of the important reasons affecting the stable operation of electrical equipment. [0003] Conductive dust (such as coal dust, metal dust, etc.) deposits on the conductor or enters the machine or instrument will cause safety hazards and affect the service life of the machine or instrument. The installation of ventilators is the main way to ventilate the substation indoors. At present, the filter screens of m...
