Electrified lubricator of high voltage isolating switch

Abstract

The invention discloses a high voltage isolator electrified oil lubricator. The main body of the oil lubricator is an insulating box lubricator (1) with an insulating rod (2), an oil outlet nozzle (41) on the box lubricator (1) is connected with an oil outlet pipe (4) inside the box lubricator; the oil outlet pipe (4) is provided with a fixed piston (5) and a moveable cylinder body (6); the bottom surface of the moveable cylinder body (6) is provided with an oil inlet hole (61); an oil inlet spring (62) and an oil inlet steel ball (63) are arranged between the fixed piston (5) and the oil inlet hole (61); the piston (5) is provided with an oil outlet (51); an oil outlet spring (52) and an oil outlet steel ball (53) are arranged between the oil outlet hole (51) and the oil outlet pipe (4); a pull rod (7) arranged outside the moveable cylinder body (6) is connected with a lever (8); and the lever (8) is connected with an oiling handle (3) through an insulating pull rod (10). The oil lubricator completes oiling lubrication to a high voltage isolator under the electrified state, brings the convenience to state maintenance, and reduces abnormal power failure.

Description

technical field [0001] The invention relates to electric power maintenance equipment, in particular to a live oil injector for a high-voltage isolating switch. Background technique [0002] In the power system, the function of the high-voltage isolating switch is to cut off or close the high-voltage line no-load, load current and fault current, so as to ensure the safe operation of the system. In the operation mode, the switch operation is performed, and the maintenance personnel need to have an obvious disconnection point for the isolation voltage. Since 80% of the operating environment of the isolating switch is outdoors, it is greatly affected by the dust and air impurities in the external environment, which may easily cause corrosion of the exposed transmission parts, and the maintenance is only carried out once a year or two years, because regular lubrication cannot be carried out. , the transmission parts (bits) have less movement and cannot get good oiling and lubric...

AI Technical Summary

Problems solved by technology

Since 80% of the operating environment of the isolating switch is outdoors, it is greatly affected by the dust and air impurities in the external environment, which may easily cause corrosion of the exposed transmission parts, and the maintenance is only carried out once a year or two years, because regular lubrication cannot be carried out. , the transmission parts (bits) have less movement and cannot get good oiling and lubrication treatment, frequent operation difficulties, heavy pulling and closing, and, due to the corrosion between the transmission rod and the shaft, the deformation and damage of the transmission parts such as the connecting rod, Increase the labor intensity of the operator, increase the number of maintenance, and more importantly, often need to operate the upper level isolating switch to complete the power failure, which affects the economic benefits of the enterprise

[0003] At present, the oiling tool used for lubricating the high-voltage isolating switch is a commercially available metal oil pot for hand, and there is no insulating oiling tool used for conditional maintenance that can be completed in a charged state.
