A live lubrication device for an isolating switch

Abstract

The invention discloses an electrified lubricating device for an isolating switch. The electrified lubricating deice comprises an oil pump system, a first oil tube, a second oil tube, an insulating tube and an oil nozzle, wherein the oil pump system comprises an oil storage pot and an oil pump, and the oil storage pot is connected with an oil inlet of the oil pump by virtue of the first oil tube; and the oil nozzle is connected with one end of the insulating tube, one end of the second oil tube is connected with an oil outlet of the oil pump, and the other end of the second oil tube extends into the insulating tube and is connected with the oil nozzle. The electrified lubricating device disclosed by the invention can be used for adding a lubricant to a transmission part of the isolating switch in an electrified manner, and by virtue of periodical lubrication, the problems that unsmooth blockage caused by the reason that the isolating switch is not operated and overhauled for a long time is generated, and the isolating switch and a ground switch cannot be connected and disconnected in place and cannot be connected and disconnected are greatly eliminated, so that the running reliability and power supply reliability of the isolating switch are improved, and the economic benefit of an enterprise is improved; and by using the electrified lubricating device disclosed by the invention, climbing operations of maintenance personnel can be avoided, and thus the safety risk of the maintenance personnel can be reduced.

Description

technical field [0001] The invention relates to an electric power tool, in particular to a live lubricating device for an isolating switch. Background technique [0002] High-voltage isolating switch is the most widely used high-voltage switchgear in the power system. Since the installation and operating environment of the high-voltage isolation switch are relatively harsh, and it operates in the open air without shelter, it is most directly affected by the environment and climate. The state maintenance system and the maintenance cycle of the main equipment are gradually prolonging. The operation is caused by the jamming of the transmission parts due to the long-term failure of the isolating switch, which causes the opening and closing of the isolating switch to be in place; the grounding switch cannot be opened and other power outage accidents continue to occur. And it is on the rise, which directly affects the reliability and security of the power supply of the system. N...

Problems solved by technology

[0003] However, since the transmission part of the isolating switch is at the lower part of the isolating switch porcelain bottle, the height of a section of the porcelain bottle is about 1.1 to 1.2 meters, and the distance from the live part is less than 3.0 meters and 1.5 meters stipulated in the safety regulations. Therefore, if the isolating switch needs to be lubricated, it must be Power failure will cause losses to users and the company, and also increase the working pressure of maintenance personnel: during single-interval maintenance work, it is necessary to close the grounding switch of the isolating switch on the bus side, but because the grounding switch on the bus side has not been maintained for a long time, it is easy As a result, the grounding switch cannot be opened after the grounding switch is closed. At this time, the entire busbar needs to be powered off, and the isolating switch on the busside side is out of power, so that the grounding switch can be processed.

It takes at least 2 hours to operate the entire section of the bus, and it takes 2 hours to restore the operation of the bus, which causes at least 4 hours of power waste; the installation position of the isolating switch is at least 2 meters above the ground, and it is a Working at heights increases the safety risk of falling from heights
