| description | The invention discloses a water-cooling frequency converter emergency protection device of a vacuum pump, belongs to the technical field of vacuum pumps, and aims to solve the unsafe problems that when a frequency converter shell leaks water under the action of external force or aging, cooling water leaks, and when the cooling water immerses into a frequency converter, namely other electrical equipment, a short circuit is extremely easy to generate and the like. The frequency converter comprises a frequency converter shell and installation plates fixedly installed on the outer walls of one sides of the two ends of the frequency converter shell respectively, an emergency push-up installation plate is installed on the bottom face of an inner cavity of the frequency converter shell, and plugging door plates are movably installed at the two ends of an opening in the top face of the frequency converter shell respectively. One side of one end of the bottom face of the frequency converter shell is fixedly provided w |
