Abstract
The technical scheme of the invention provides a spring energy storage indicating device of an operation mechanism. The device is characterized by comprising a shaft, wherein the shaft is connected with the front end of a spring pull rod through a bearing and is fixed on an energy storage driving wheel; a stud is fixed on the shaft; and one end of a shift fork is connected with the stud and the other end of the shift fork is connected with an indicating arrow on an energy storage indicator board to make the indicating arrow rotated together with the shaft. The indicating device can reliably indicate the energy storage state of a brake closing spring, and cannot be bent or broken.
Description
Technical field
The present invention relates to a kind of high pressure equipment for power transmission and distribution breaker operation mechanism switching-in spring energy storage indicating device, major function is to solve the positive energy storage state that shows the switching-in spring of spring mechanism of circuit breaker.
Background technology
Circuit breaker is a switchgear important in the electric power system, undertaking the double action of control and protective circuit, and in circuit breaker, operating mechanism is its vitals again.In operating mechanism, give the switching-in spring energy storage by stored energy mechanism.When circuit breaker disconnected, switching-in spring is energy storage.During combined floodgate, switching-in spring releases energy.When switching-in spring had discharged energy, motor began to the switching-in spring energy storage.
Therefore, need an indicating device to indicate the energy storage state of switching-in spring, still, existing indicating device is unreliable, has more existing indication bending and phenomenon of rupture.
Summary of the invention
It is reliable to the purpose of this invention is to provide a kind of indication, is not prone to the indicating device of the switching-in spring energy storage state of indication bending and phenomenon of rupture.
In order to achieve the above object, technical scheme of the present invention has provided a kind of spring energy-storage indicating device of operating mechanism, it is characterized in that: comprise axle, axle links to each other by the front end of bearing with the spring pull bar, axle is fixed on the energy storage driving wheel, and double-screw bolt is fixed on the axle, and an end of fork links to each other with double-screw bolt, the other end connects the arrow on the energy storage direction board, makes arrow follow the axle rotation.
Further, an end of described fork links to each other with described double-screw bolt by kidney slot.
The invention provides a kind of indicating device of indicating reliable switching-in spring energy storage state, this indicating device can not bend and rupture.
Description of drawings
Fig. 1 is the spring energy-storage indicating device schematic diagram of a kind of operating mechanism provided by the invention.
Embodiment
For the present invention is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figure 1, the spring energy-storage indicating device of a kind of operating mechanism provided by the invention, comprise axle 8, axle 8 links to each other by the front end of bearing with spring pull bar 9, axle 8 is fixed on the energy storage driving wheel 4, and double-screw bolt 7 is fixed on the axle 8, and an end of fork 6 links to each other with double-screw bolt 7 by kidney slot, the other end connects the arrow on the energy storage direction board 2, makes arrow follow axle 8 rotations.
When 1 energising of mechanism's energy storage motor is rotated, pass through Bevel Gear Transmission, drive energy storage driving wheel 4 and rotate counterclockwise, axle 8 is fixed on the energy storage driving wheel 4, therefore, axle 8 rotates counterclockwise around energy storage driving shaft 4 centers, spring pull bar 9 is connected by bearing with axle 8, and spring pull bar 9 is to left movement, spring stop 12 and spring pull bar employing bolt, spring pull bar 9 drives spring stop 12 in the time of moving excessively and is moved to the left, thereby makes energy-stored spring 10 compressions carrying out energy storage action.
Double-screw bolt 7 is fixed on the axle 8, double-screw bolt 7 rotates counterclockwise around energy storage driving shaft 4 centers, fork 6 inserts in the double-screw bolt 7, when rotating fork 6 is rotated counterclockwise around energy storage driving wheel 4 centers, indicating arm 3 is one with fork 6 welderings, arrow on the energy storage direction board 2 is fixedlyed connected with indicating arm 3, thereby arrow is rotated counterclockwise, and realizes deixis.
Stop after spring energy-storage puts in place, finish energy storage state, energy storage direction board 2 upward arrow directions left.When spring energy release, motion conditions is opposite, gets back to initial condition.
Claims (2)
