Description

Technical Field

[0001] The utility model relates to the technical field of frames, in particular to a frame of a vacuum electromagnetic starter for mining. Background Art

[0002] The explosion-proof vacuum electromagnetic starter for mining is mainly used to control the direct start, stop and forward and reverse operation of mining induction motors, and can protect the motors from overload and phase failure. It adopts a quick-opening door structure, which is simple and reasonable, easy to operate, and the body adopts a vertical plate type, using a simple control circuit for easy maintenance. The starter starts and stops the load at a long distance, and has protection functions such as overload, phase failure, short circuit, and leakage lock detection.

[0003] At present, the frame of the vacuum electromagnetic starter for mining in the prior art is usually used to support the starter and separate it from the ground. When in use, since the starter is used in a mine and the connecting wire connected to it is protected by a pipe on the outside, the height of the frame cannot be adjusted, and it is not convenient to connect the connection of the starter with the pipe of the connecting wire, which makes it more troublesome to connect the starter with the connecting wire. There is a problem that the height of the frame cannot be adjusted. In addition, when in use, the inside of the starter is in a vacuum state, and there is no protective structure outside the starter. If the starter is hit, it is easy to cause a gap in the starter, allowing air to enter the inside of the starter, and there is a problem that the starter cannot be protected. Utility Model Content
