Anti-overturning insulating ladder for substation maintenance operation

Abstract

The invention belongs to the field of substation maintenance, and particularly relates to an anti-overturning insulating ladder for substation maintenance operation. Aiming to solve the problem that the insulating ladder often overturns due to the action of the gravity of an overhaul worker and cannot meet the requirement during overhaul construction due to the fact that an overhaul site is oftenlocated on muddy land and geologies are different, the technical scheme is provided. The insulating ladder comprises an insulating ladder body; rotating grooves are symmetrically formed in the bottomend of the insulating ladder body; placing grooves are formed in the top ends of the rotating grooves; the placing grooves are formed in the insulating ladder body; clamping grooves are formed in theinner walls of the placing grooves; and a rotating shaft is movably arranged between the inner walls of the rotating grooves. The anti-overturning insulating ladder for substation maintenance operation is simple in structure and convenient to carry, and the insulating ladder body can be effectively prevented from turning over, so that normal and orderly operation of substation maintenance operation is guaranteed, and the use requirement is met.

Description

technical field [0001] The invention relates to the technical field of substation maintenance, in particular to an insulation ladder for preventing overturning during substation maintenance operations. Background technique [0002] Power transformation refers to the process of changing the voltage from low level to high level (boost) or from high level to low level (step down) through certain equipment in the power system. The rated voltage of the generator in the power system is generally below (15-20) kV. Commonly used transmission voltage levels are 765 kV, 500 kV, 220-110 kV, 35-60 kV, etc.; distribution voltage levels are 35-60 kV, 3-10 kV, etc.; Electrical appliances have high-voltage electrical equipment with a rated voltage of 3-15 kV and low-voltage electrical equipment such as 110 volts, 220 volts, and 380 volts. Therefore, the power system is to connect parts of different voltage levels through substation to form a whole. The place where the power transformatio...
