Embodiment Construction

[0019] The invention relates to a mechanical linkage mechanism for a double power supply switch and a double power supply switch containing the mechanism.

[0020] figure 1 A schematic diagram of a main shaft 1 and a trip bar 2 in a circuit breaker is shown. In the circuit breaker, the main shaft 1 of the circuit breaker is connected with its movable contact, driven by the circuit breaker mechanism, the main shaft 1 figure 1 The view shown in the figure rotates counterclockwise to drive the moving contact and the static contact to close, thereby realizing the "closing" operation of the circuit breaker; similarly, in the closing position, with figure 1 The clockwise rotation of the shown view drives the moving contact to separate from the static contact, thereby realizing the "opening" operation of the circuit breaker.

[0021] Combine below figure 1 Describe the trip lever 2 of the circuit breaker. When the trip lever 2 is turned to make it reach the trip position, the cir...

Abstract

A mechanical linkage mechanism and a dual power supply switch, the dual power supply switch has: a first power supply, a first main shaft and a first tripping lever, a second power supply, a second main shaft and a second tripping lever, and the mechanical linkage mechanism includes : a first linkage rod connected with the first main shaft and rotating together with the first main shaft, a first drive rod sliding along the first linkage rod, and a first return spring arranged between the first linkage rod and the first drive rod ; The second trip lever, which is connected to the rotation shaft of the second trip lever through the first torsion spring, and cooperates with the first linkage lever, the first drive lever and the first return spring to complete the linkage operation; connected with the second main shaft and a second linkage lever that rotates with the second spindle, a second drive lever that slides along the second linkage lever, and a second return spring; and a first trip lever that is connected to the first trip lever through a second torsion spring The rotating shaft of the rod, and cooperate with the second linkage rod, the second drive rod and the second return spring to complete the linkage operation.

Description

technical field [0001] The invention relates to a mechanical linkage mechanism for a double power supply switch and a double power supply switch containing the mechanism. Background technique [0002] The transition time of a dual power transfer switch (TSE) is a product performance parameter that many engineers in the industry are very concerned about. It is related to the nature of the load and its application. For some loads or important power consumption places, a short conversion time (such as less than 100ms) is necessary. [0003] Existing TSEs are divided into two categories, namely derived and original. The derivative type is a TSE composed of two existing low-voltage switch products (such as circuit breakers or isolating switches) through a mechanical operating device and other necessary accessories. It has the advantages of simple structure, stable performance (depending on the low-voltage switch product used), less investment, etc., but also has the disadvantag...
