Abstract
The utility model discloses an opening spring device for a circuit breaker. The opening spring device for a circuit breaker improves a present opening spring device for the circuit breaker, additionally provides a guide sleeve on a pad and a guide pin on an underpan. The utility model with above design, completely solves a problem of interference and collision during acceleration of the opening spring and closing a pull rod in the present opening spring device for the circuit breaker, thereby effectively ensuring the closing and opening speed and increase life time of the opening spring device for the circuit breaker.
Description
Technical field:
The utility model relates to a kind of circuit breaker energy-stored spring assembly tool is installed, and belongs to machine tool manufacturing technology field.
Background technology:
Existing circuit breaker mechanism tripping spring device mainly comprises chassis 1, housing 2, separating brake acceleration spring 3, tripping spring 4, backing plate 5, connecting lever 6, pin 7, pull bar 8, oscillating bearing 9, spacer 10, axle 11 as shown in Figure 1; Pull bar 8 is connected by oscillating bearing 9, spacer 10 and axle 11 with chassis 1, and a copper sliding sleeve respectively is equipped with at the two ends of axle 11, can slippage up and down in the groove of housing 2.Spacer 10 places oscillating bearing 9 both sides, and oscillating bearing 9 is played the axial location effect.Tripping spring 4 upper ends contact with backing plate 5, and the lower end is loaded on the step cylindrical on chassis 1.Separating brake acceleration spring 3 upper ends do not contact with backing plate 5, and the lower end is loaded on the end face on chassis 1.Two springs and chassis 1, backing plate 5 all place housing 2.Pull bar 8 is connected by a pin 7 with connecting lever 6.Pull bar 8 uppermost holes connect the three-phase moving contact of circuit breaker.When mechanism closes a floodgate, rely on the energy-stored spring energy to discharge, make connecting lever 6 be rotated counterclockwise certain angle around its center, by pin 7, mention pull bar 8, chassis 1 is put on together by oscillating bearing 9, axle 11, makes tripping spring 4 and separating brake acceleration spring 3 be in the energy storage state.When mechanism's separating brake, rely on the energy of tripping spring 4 and separating brake acceleration spring 3 to discharge, fast chassis 1 is depressed, be about to pull bar 8 and leave behind rapidly, the three-phase dynamic/static contact separates rapidly.Though this device structure is comparatively simple,, tend to produce the problem of following several respects owing to lack perfect spring guiding.(1) separating brake acceleration spring 3 and pull bar 8 can interference and collision, especially making processes in, when connecting lever 6 was rotated counterclockwise around its center, some swung pull bar 8 upper ends, easier both was interfered, and caused the loss of mechanism's combined floodgate merit, it is not in place that mechanism is closed a floodgate.(2) because the draw ratio of two springs is all bigger, be easy to generate unstability when length of spring compressed, make the energy of spring can not be used for separating brake fully, opening velocity is also unstable.(3) the spring upper end lacks guiding, also easily causes the knockdown of lower chassis 1, and chassis 1 and housing 2 inwalls are interfered, and influences mechanism's combined floodgate, opening velocity and useful life.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of simple and reasonable for structure, and combined floodgate and opening velocity are fast, and the breaker mechanism tripping spring device of long service life.
Breaker mechanism tripping spring device described in the utility model is that it is to have added fairlead on backing plate, and has added guide finger on the chassis to the improvement of existing circuit breaker mechanism tripping spring device and perfect.Through the utility model after the above-mentioned design, thoroughly solved the problem of existing circuit breaker mechanism tripping spring device interference and collision in separating brake acceleration spring and pull bar making process, guaranteed combined floodgate and opening velocity effectively, and improved the useful life of breaker mechanism tripping spring device.

Embodiment:
A kind of breaker mechanism tripping spring device comprises chassis 1, housing 2, separating brake acceleration spring 3, tripping spring 4, connecting lever 6, pin 7, pull bar 8, oscillating bearing 9, spacer 10, axle 11; Pull bar 8 is connected by oscillating bearing 9, spacer 10 and axle 11 with chassis 1, and a copper sliding sleeve respectively is equipped with at the two ends of axle 11, can slippage up and down in the groove of housing 2.Interior upper end at housing 2 is provided with fairlead 12, has established the second gear step on the fairlead 12, and the big step cylindrical of fairlead 12 matches with tripping spring 4 upper end endoporus, and the small stair cylindrical of fairlead 12 matches with separating brake acceleration spring 3 upper end endoporus; On the end face on chassis 1, be provided with four guide fingers 13 in addition; Four guide fingers 13 are used for the lower end endoporus guiding of separating brake acceleration spring 3 on same circumference, also available fairlead leads.
The utility model is owing to added fairlead and guide finger, so breaker mechanism tripping spring device is in separating brake acceleration spring and pull bar making process, the problem that mutual interference and collision can not occur, thereby guaranteed combined floodgate and opening velocity effectively, and improved the useful life of breaker mechanism tripping spring device.
