Abstract
The utility model discloses a manual pressure compensating device for an electric power breaker hydraulic mechanism, which comprises a gear plate arranged on an output shaft of a motor, wherein the side surface of the gear plate is provided with a base matched with the gear plate, the base is provided with two brackets, the two brackets are provided with a lever through a hinge pin, and the front end of the lever is provided with a rack. When the motor is de-energized or breaks down and cannot operate normally, the lever is pressed in a reciprocating mode, the circular arc-shaped rack drives the gear plate to rotate, no manner whether the lever moves upward or downward, the circular arc-shaped gear at the front end of the lever drives the gear plate, and the gear plate drives an oil pump output shaft to enable an oil pump to operate, thereby completing pressure compensation for the breaker hydraulic mechanism, ensuring the breaker hydraulic mechanism to always stay at nominal pressure, ensuring normal operation of a breaker, and enabling an electric power system to operate safely and stably. The circular arc-shaped rack enables all teeth on the rack to be contacted with the gear plate, the lever moves in a reciprocating mode, and an effect that the gear plate is driven to rotate is good.
Description
Technical field
The utility model relates to a kind of circuit breaker compensation device technical field, particularly the manual compensation device of a kind of power circuit breaker hydraulic mechanism.
Background technology
Traditional circuit breaker compensation device, after charged by motor, drive oil pump running by output shaft, low pressure oil is converted to hydraulic oil and be stored in accumulator, for the breaking-closing operating of circuit breaker provides power, the output shaft between motor and oil pump is connected by shaft coupling at any time.When motor dead electricity or break down can not run well time, if now Hydraulic Mechanism of Circuit-breaker pressure is lower than rated value, be badly in need of ftercompction, obviously traditional structural configuration cannot meet the demands, circuit breaker, also by forced outage, directly has influence on the safe and stable operation of electric power system.
Utility model content
The utility model is exactly for the problems referred to above, provides a kind of power circuit breaker hydraulic mechanism manual compensation device, when motor dead electricity or break down can not run well time, still can ensure hydraulic mechanism normal fuel injection, ensures the safe and stable operation of electric power system.
For achieving the above object, the utility model adopts following technical scheme, the manual compensation device of a kind of power circuit breaker hydraulic mechanism, comprise the toothed disc being arranged on motor output shaft, the side of described toothed disc arranges the base matching with toothed disc, two supports are set on this base, between two supports, by bearing pin, lever are installed, lever front end arranges tooth bar.
Described tooth bar adopts the arc-shaped rack matching with toothed disc.
The center of circle of described arc-shaped rack is positioned at bearing pin place.
The utility model in use, when motor dead electricity or break down can not run well time, now reciprocal presses lever, arc-shaped rack driven gear dish rotates, no matter lever is up or down, lever nose circle arc gear wheel driven gear dish, toothed disc drives again oil pump output shaft to make oil pump running, thereby complete the ftercompction work of Hydraulic Mechanism of Circuit-breaker, to guarantee that Hydraulic Mechanism of Circuit-breaker is all the time in rated pressure.Ensure normal operation of circuit breaker, make power system safety and stability operation.Arc-shaped rack makes the tooth on tooth bar can contact with toothed disc, lever reciprocating motion, and driven gear dish rotating effect is good.
Brief description of the drawings
