Manual control type power transformation equipment high-voltage equipotential oil distribution gun with free suction pipe

Abstract

The invention provides a manual control type power transformation equipment high-voltage equipotential oil distribution gun with a free suction pipe. A purely-mechanical switch structure is adopted, and the oil spraying reliability is greatly improved. An oil suction hose and a gravity oil suction head are arranged at the lower portion of an oil chamber, when the oil chamber is vertically or obliquely placed, the hose arranged in the oil chamber is bent in the gravity direction under the gravity action of the gravity oil suction head, the tail end of the hose is constantly immersed in lubricating oil, lubricating oil in the oil chamber can be sufficiently sucked, accumulated oil in the oil chamber is effectively reduced, the lubricating oil utilization rate is greatly improved, and the oiladding frequency is reduced. The manual control type power transformation equipment high-voltage equipotential oil distribution gun is simple in structure and convenient to dismount and mount, the safety of the installing and using process of the whole device is high, time and labor are saved, great convenience is achieved, safety and reliability are achieved, and the work efficiency is greatly improved; and the manual control type power transformation equipment high-voltage equipotential oil distribution gun can be repeatedly utilized, and is economical, practical, flexible in usage, reasonable in design, compact in structure and suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of electric power system equipment, in particular to a high-voltage equipotential oil distribution gun for hand-controlled substation equipment with a free suction pipe. Background technique [0002] The isolating switch is a device with the largest number and types of substations. Most outdoor installations are greatly affected by environmental factors. After long-term operation, the lubricating oil in the rotating part of the transmission link of the disconnector and the contact part of the moving and static contacts dries up, and is affected by dirt and corrosion factors. Since the knife switch is electrified, it cannot be lubricated. Only the isolating switch is powered off for maintenance. Since the isolating switch is mostly connected to the busbar, once it is overhauled, the busbar needs to be powered off, requiring a lot of operations and the power outage range is large, which affects system safety ...

AI Technical Summary

Problems solved by technology

Most of the outdoor installations are greatly affected by environmental factors

After long-term operation, the lubricating oil on the rotating part of the transmission link of the disconnector and the contact part of the moving and static contacts is dry, and is affected by dirt and corrosion factors.

Since the knife switch is electrified, it cannot be lubricated. Only the disconnector is powered off for maintenance. Since the disconnector is mostly connected to the busbar, once it is repaired, the busbar needs to be powered off, requiring a large number of operations and the power outage range is large, which affects system safety and power supply reliability.
