Sweeping device of power distribution panels, boxes and cabinets of 750 kilovolt transformer substation

Abstract

The invention discloses a sweeping device of power distribution panels, boxes and cabinets of a 750 kilovolt transformer substation. The sweeping device comprises a device body, a dust suction pipe interface for being connected with one end of a dust suction pipe is formed in the device body, and the other end of the dust suction pipe is connected with a dust suction pipe clamping port of a sweeping control handle. The device body comprises a bottom box body and a device top cover which are connected through a box body buckle. An infrared receiving device is arranged on the outer surface of the top of the device top cover, the device body further comprises a dust suction / blowing module, a mode switching module and a power source module. The dust suction / blowing module comprises a draught fan driven by a variable frequency motor which can rotate forwards and backwards, and an air duct of the draught fan communicates with the dust suction pipe interface of the device body. A sweepinghead connection port is connected with a sweeping head clamping port of a sweeping connection head. The sweeping connection head comprises a shell, one end of the shell of the sweeping connection head is the sweeping head clamping port, and the other end of the sweeping connection head is a telescopic sweeping head. The shell further comprises a deformation bend with the angle being adjustable.

Description

technical field [0001] The invention relates to a substation cleaning device, which is specifically used for daily operation and maintenance cleaning of three boxes of screen cabinets in a 750 kV substation. Background technique [0002] The three boxes of substation equipment screen cabinets can be divided into outdoor type and indoor type according to the placement location. Equipment protection screen cabinets are generally installed indoors, with less dust than outdoors, but there is also the phenomenon of dust accumulation and heat generation. The equipment mechanism box and intelligent central control cabinet are installed in the outdoor environment. Most of the substations are located in harsh environments and climate-changing areas or adjacent to large-scale heavily polluted factories. Dust, pollution and sand particles generated by heavy pollution are easy to accumulate in The smart electronic device plug-in, circuit board, connection lead terminal block, and cable ...

AI Technical Summary

Problems solved by technology

750 kV Class I and II large-scale substations each have hundreds of screen cabinets and three boxes, the cleaning task is heavy and the cleaning effect is poor

After the three boxes of the screen cabinet have been running for a long time, dust that is not easy to clean will accumulate on the intelligent electronic equipment, terminal blocks, cables and components in the box, which will reduce the electrical insulation level. Failure, affecting the safe and stable operation of the equipment

[0005] Due to environmental pollution, sand and dust climate and other factors in substation indoor protective screen cabinets, outdoor intelligent central control cabinets, and circuit breaker mechanism boxes, if the three boxes of screen cabinets are not promptly and thoroughly cleaned of dirt and dust, the three boxes of screen cabinets will be damaged. The safe operation of internal intelligent electronic devices and connected components poses a great threat

[0006] To sum up, in the cleaning process of the existing operation and maintenance work, it is difficult to guarantee the effect by manual methods (hand-held improved brooms, brushes and other tools), and the efficiency is very low; there are potential safety hazards
