Embodiment Construction

[0019] see Figure 1-Figure 6 , this specific embodiment adopts the following technical scheme: it comprises a large gear 1, a pinion 2, an energy storage shaft 3, a floating rack 4, a pin shaft 5 and a return spring 6, the pinion 2 is arranged on the energy storage shaft 3, The intermeshing part of the large gear 1 and the pinion 2 removes a part of the teeth of the large gear 1, and is processed into a groove shape inside the base without teeth, and a floating rack 4, a pin 5 and a return spring 6 are installed in the groove. The rack 4 has three teeth, and the parameters of the teeth are the same as those of the large gear 1 . The floating rack 4 rotates around the pin shaft 5 under the force of the return spring 6 .

[0020] One side of the energy storage shaft 3 is also provided with an overrunning clutch 7. During the energy storage process of the closing spring, the torque from the motor can be transmitted to the energy storage shaft 3 through the reduction gear, and du...

Abstract

The invention relates to a spring operating mechanism of a high-voltage circuit breaker. The spring operating mechanism consists of a rack wheel, a pinion, an energy storage shaft, a floating toothed bar, a pin shaft and a reset spring; the pinion is arranged at the energy storage shaft; parts of teeth of the rack wheel are removed at the mutual engagement portion of the rack wheel and the pinion; and the base body inside portion with no tooth is processed into the groove-shaped portion and the floating toothed bar, the pin shaft, and the reset spring are installed in the groove. The floating toothed bar has three teeth, wherein the parameters of the teeth are identical with that of the rack wheel. The floating toothed bar rotates around the pin shaft under the force of the reset spring. With the mechanism, all problems of opening and closing operations including closing spring energy storage and closing spring energy releasing can be solved, so that the energy storage-closing operation-opening operation process required by the spring operating mechanism of the circuit breaker can be executed correctly and reliably.

Description

Technical field: [0001] The invention relates to a high-voltage circuit breaker, in particular to a spring operating mechanism of the high-voltage circuit breaker. Background technique: [0002] The requirements of the circuit breaker operating mechanism are to perform opening and closing operations in accordance with the standard to complete the opening and closing of the power circuit. [0003] Opening operation process: Because the opening spring has the force, the arm has a clockwise torque around the output shaft. When the opening trigger coil is excited, it hits the opening release and rotates counterclockwise, and the lock bolt A is lifted by the pin A. At this time, the arm rotates clockwise, and the movable contact of the circuit breaker is driven by the connecting rod A to move to the opening position. [0004] The process of closing operation (that is, the release of closing spring energy, the same below): after the closing trigger coil is excited, the impact clo...
