Embodiment Construction

[0019] Examples of high voltage switches, such as Figure 1-4 As shown, the high-voltage switch in this embodiment is a 126kV sulfur hexafluoride circuit breaker, which includes a bracket, an operating mechanism assembled on the bracket, a control box, a three-phase interrupter and an energy storage device.

[0020] The operating mechanism comprises a driving motor and a transmission main shaft, and the structure of the driving motor 10 is as follows: Figure 3-4 As shown, it includes a permanent magnet 1 , an armature winding 2 , a motor rotor 3 , a motor stator 4 , a base 5 and a motor shaft 6 . The driving motor 10 has stator teeth, and the number of the stator teeth is 12. The rotor has rotor teeth, and the number of the rotor teeth is 10. The 12 permanent magnets 1 are respectively embedded in the stator teeth, providing a larger air force for the driving motor. The gap flux density makes the motor have large electromagnetic torque and good starting performance. Since t...

Abstract

The invention relates to the field of high-voltage switches, in particular to a high-voltage switch operation mechanism and a high-voltage switch using the high-voltage switch operation mechanism. The high-voltage switch operation mechanism comprises a driving motor, wherein the driving motor comprises a motor main shaft, a permanent magnet, a motor rotor and a motor stator, wherein the permanent magnet is fixedly arranged on the motor stator. The high-voltage switch operation mechanism has the advantages that the permanent magnet of the driving motor is fixedly arranged on the motor stator, so in the use process, the permanent magnet does not rotate along with the motor rotor, and the displacement and falling of the permanent caused by the emergency shutdown of the motor rotor because of inertia force are fundamentally avoided; the problem of easiness in fault of the existing high-voltage switch operation mechanism is solved.

Description

technical field [0001] The invention relates to the field of high-voltage switches, in particular to a high-voltage switch operating mechanism and a high-voltage switch using the mechanism. Background technique [0002] The high-voltage switch is one of the most critical components in the power transmission system. According to the current operating statistics of the high-voltage switch, more than half of the failures of the high-voltage switch are caused by the failure of the operating mechanism. In the operating mechanism driven by a motor, The vast majority of failures come from the failure of the drive motor. [0003] At present, the main components of a drive motor used in a high-voltage switch operating mechanism include a motor shaft, a permanent magnet, a motor rotor, a motor stator, and a rotary encoder. Wherein the motor rotor, the permanent magnet and the rotary encoder are all fixedly assembled on the motor shaft. When the high-voltage switch is opened and clo...
